Authors: Chen Mei-Lun , Lou Shi-Jer , Tsai Wei-Fang , Tsai Chih-Cheng
Published: September 2021

This study adopts both quantitative and qualitative methods. There are 23 subjects in the experimental group and the control group. The experimental group received the “Green Giant Growth Group” test once a week for a total of 7 times. The measurement tools were scale of self-concept, Chinese well-being and horticultural effectiveness. With respect to data analysis, the researcher adopted descriptive statistics and analysis of covariance. Feedback and interviews were included in the qualitative analysis. According to the findings of this study, horticultural activities can enhance students’ self-concept, sense of control, self-satisfaction, sense of achievement and social skills. Based on the results of interviews, by participating in horticultural activities, students increase their interpersonal relationship skills. Their behaviors match social norms, and they are more responsible, open-minded and peaceful. In line with previous research findings, this study proposes suggestions for future researchers to apply horticultural activities in education or guidance.

FOSTERING STUDENT’S CREATIVE AND PROBLEM-SOLVING SKILLS THROUGH A HANDS-ON ACTIVITY
Authors: Shieh Ruey-Shyy , Chang Wheijen
Published: September 2021

The purpose of this study is to investigate how a group of junior-high school pupils created a functional boat from scratch and resolved the problems encountered in a scientific project. The study was conducted using a qualitatively exploratory method. Data sources consist of artefacts, interviews, observations, and self-reflection reports. The study results reveal that the hands-on, trial-and-error experiential learning not only helped the pupils enhance their creative skills and problem-solving abilities, but also helped them realize the value of collaboration. Nevertheless, although they were able to make various shapes of boats using different materials, only half of the boats created were able to successfully complete the established course. It discloses that turning a model work into a functional piece demands a certain extent of scientific knowledge and skills associated with the tasks, in addition to creative skills. The students’ anticipation of the teacher’s scaffolding to achieve the project goal was found to vary greatly among teams, indicating a dilemma of the teachers’ role in an open-form scientific project. How the created products were ranked in the project also raises concerns regarding setting up criteria to assess scientific artefacts. Suggestions for enhancing future implementations are provided.
Key words: boat creation, collaborative learning, hands-on skills, problem solving skills.

Published: September 2021

The aim of this study is to reveal teacher educators’ views of model and also to determine their mental models about it. Phenomenographic research design has been carried out in this study. The sample of study consists of 14 teacher educators from education faculties of different universities in Turkey. Semi-structured interviews that consisted of 7 questions were used to collect data. Besides, sample was asked draw a concept map on “model” in the last interview question. Results have shown that teacher educators give similar responses including unqualified explanations to the interview questions related to the definition of model, characteristics of them, and the objectives of using models. It can also be asserted, that teacher educators do not have scientific understanding on the modeling process. The analyses of their responses to the interview questions and their concept maps have shown that most of the teacher educators in the sample have proximate or goal oriented mental models of the “model”. Considering the results, it is suggested that teacher educators should not only follow the new theories, methods, or the applications in related literature theoretically, but also employ different theories, methods, or applications such as models and modeling in their courses. Key words: model, modeling, teacher educators, mental model.
CONCEPTS OF VEGETABLE AND FRUIT IN PRESCHOOL AND ELEMENTARY EDUCATION
Authors: Eş Hüseyin
Published: September 2021

The purpose of this study was to investigate the way the concepts of fruit and vegetable are presented in teaching materials, used in pre-school education and in the textbooks of life sciences and science and technology courses in elementary education, in addition to the students and teachers’ knowledge and opinions related to these concepts. Qualitative research techniques were used in this study. The sample of the study comprises the students receiving education in pre-school and elementary education and the teachers serving at these levels. 258 students and 83 teachers took part in this study. A survey, which was developed by the researcher, including two forms, was administered. Teaching materials in pre-school education and course books in elementary education were also used as data sources. When the research findings are considered, it stands out that these concepts have different definitions in different fields and thus, they have no common definitions. This situation seems to have been reflected in the teaching materials used both in pre-school and elementary education. Also, it is seen that there are important differences between teachers’ opinions about these concepts.

PRIMARY SCHOOL CHILDREN’S IDEAS OF MIXING AND OF HEAT AS EXPRESSED IN A CLASSROOM SETTING
Authors: Haglund Jesper , Jeppsson Fredrik , Andersson Johanna
Published: September 2021

This study investigates primary school children’s (7-8 year-old, N = 25) ideas of mixing of marbles and of heat, expressed in small-group predict-observe-explain exercises, and drawings representing the children’s own analogies in a classroom setting. The children were typically found to predict that marbles of two different colours would mix when rocked back and forth on a board. This idea of mixing is slightly more advanced than previously reported in the literature. The children’s ideas of heat included reference to warm objects, their own bodies when exercising, and the process of one warm solid object heating another object in direct contact. In addition, through scaffolding, some of the children expressed a substance view of heat. Finally, the potential and challenges in probing children’s ideas through a combination of data collection techniques in a classroom setting are reflected upon.

DEVELOPMENT AND EVALUATION OF A COMPETENCE-BASED TEACHING PROCESS FOR SCIENCE AND TECHNOLOGY EDUCATION
Authors: Pešaković Dragica , Flogie Andrej , Aberšek Boris
Published: September 2021

The quality of education is increasingly being measured less by the knowledge gained during schooling and more by the level of competence possessed by students at doing a particular job after completing their education. Target and process-planned curricula are being replaced more and more by competence-oriented curricula, especially in science and technology education, where competences, generally defined as the capability or the ability of an individual doing a job properly, are placed at the forefront.
If competence is the desired criterion for educational quality, it can be easily established that suitable instruments and methods of measurement are needed for this kind of quality evaluation, which, however, are not yet available. Suitable instrumentation was developed in this study. Its use was demonstrated in the example of elementary education in Slovenia.

PEER INSTRUCTION IN THE PHYSICS CLASSROOM: EFFECTS ON GENDER DIFFERENCE PERFORMANCE, CONCEPTUAL LEARNING, AND PROBLEM SOLVING
Authors: Gok Tolga
Published: September 2021

The purpose of this study was to examine the effects of peer instruction (PI) on performance, gender gap, conceptual learning and problem solving in physics. The students enrolled in two sections of a physics course were selected; one section was treatment group (TG) and the other section was control group (CG). 42 students in TG were instructed with PI whereas 56 students in CG were instructed with conventional instruction. Data were collected using Force Concept Inventory, final examination problems, and students’ opinions about the instruction. The results indicated that PI had more positive effect on students’ conceptual learning and problem solving than conventional instruction. The conceptual learning with PI did not show any statistically significant difference between female and male students in TG. However, the quantitative problem solving performance after PI revealed that male students performed better than female students. The female and male students’ conceptual learning and problem solving performance did not change noticeably in CG. The students in TG also changed their perspective on solving a problem and understanding a concept. They found the method helpful to connect the quantitative solution with related concepts. Key words: conceptual learning, gender gap, peer instruction, physics education, problem solving.
EVALUATING MEASUREMENT PROPERTIES OF ATTITUDINAL ITEMS RELATED TO LEARNING SCIENCE IN TAIWAN FROM TIMSS 2007
Authors: Liou Pey-Yan
Published: September 2021

In the recent empirical studies utilizing existing items and derived variables of international large-scale assessment (ILSA) data, the three major methodological deficiencies, including the use of a single item to define a construct, the statistical properties of ordinal data, and the fitness of the measurement structure for different scenarios, are examined. To overcome these issues, this study proposes an integrated approach to evaluating items and constructing derived variables in a given situation. Exploratory factor analysis, confirmatory factor analysis, and the item response model are utilized to evaluate student attitudinal items and derived variables from the Trends in International Mathematics and Science Study (TIMSS) 2007 Taiwanese data. The results suggest that the three-factor model composed of 12 items is optimal for the data, not the default factor structure in the database. The implications of evaluating items and creating derived variables from ILSA data for the education research community are also discussed. Key words: attitudinal items, factor analysis, Trends in International Mathematics and Science Study.

Authors: Bahcivan Eralp
Published: September 2021

This study was conducted to examine the relationships among pre-service science teachers’ (PSTs’) teaching and learning conceptions, scientific epistemological beliefs and science teaching efficacy beliefs. 310 Turkish PSTs from different regions of the country participated in the study. Three different instruments were validated by confirmatory factor analyses. Structural equation modeling analyses revealed that participants’ constructivist conceptions of teaching and learning promoted sophisticated science related epistemologies. Sophisticated epistemologies, to some extent, also contributed participants’ science teaching efficacy beliefs. Certain assumptions were not supported by the results which pointed out that curricular reform in teacher education system met expectations partly. Implications were presented considering the results.

The present study has been undertaken to assess the training needs of employer on cleaner production in SAF leather industry at Jashore district in Bangladesh. Using Borich Need Assessment Model for training needs. A total 60 employers were surveyed including 20 employers from each group and data were collected on socioeconomic condition of responders, management activities in leather processing and environment pollution related issues through the questionnaire. The importance level, competence needs were analyzed and ranked using weighted discrepancy scores (WDS). The study revealed that the highest WDS score (15.38) was found for Beam house worker that indicated the training is strongly needed for them on identification of harmful chemicals and environmental pollution. Crust and fishing unit worker needed high training (WDS score= 15.10) on understanding the types and quantities wastewater discharged from industry during leather processing and its management. The WDS score 14.78 was estimated for administrative employers where they needed high training on controlling odor problem from the industry. Although they have an average knowledge about the environmental pollution, they did not have qualified level of capabilities on understanding how to use some environmental tools e.g. social impact assessment and environmental auditing. Therefore, majority of the respondents preferred training for reduction of environmental pollution.

Discriminate and indiscriminate use of amoxicillin antibiotic and detection of its residue in poultry edible tissue by thin layer chromatography (TLC) method
Authors: Islam Md Shakil , Islam Md Zahorul , Islam Md Shafiqul
Published: September 2021

Antibiotic residue is a burning question in the present world. Antibiotic remain in edible tissues of poultry as a residue due to indiscriminate use in the veterinary field. Human health is at risk of antibiotics due to poultry edible tissues. In this study, we used broiler chicks as a laboratory animal to investigate the judicial use of amoxicillin antibiotic for human health concern. Chicks were reared accordingly and on day 14 the chicks were randomly divided into three groups (n=6) namely control (group A), discriminate (group B) and indiscriminate (group C). At the age of day 16, amoxicillin treatment was started and continued for seven days for discriminate group (Group B) and 15 days for indiscriminate group. In case of discriminate group, seven days withdrawal period was properly maintained, whereas, no withdrawal period was maintained in case of indiscriminate group. In control group, no positive samples were detected by thin layer chromatography (TLC) analysis, whereas, the amoxicillin intensity in liver, kidney, thigh muscle and breast muscle were positive by TLC as 57.82%, 52.30%, 45.18% and 49.96% respectively for indiscriminate group. Similarly 46.81% liver, 44.65% kidney, 29.27% thigh muscle and 32.73% breast muscle were the amoxicillin intensity in discriminate group. The level of amoxicillin were found significantly different between control & discriminate, control & indiscriminate and discriminate & indiscriminate groups by TLC analysis. Therefore, amoxicillin residue present in both discriminate and indiscriminate group but the intensity percentage (%) was highest in case of indiscriminate group indicates high residual concentration.

Authors: Sahu Mayuri
Published: September 2021

Genetic architecture through variability parameters and association analysis for green forage yield and its characters in 78 germplasm lines including 3 checks (MFC-8-14, UPC-5286 and TSFC-12-15) was carried out during Rabi 2015-2016. All the fifteen studied characters exhibited existence of variability significantly. This indicated existence of sufficient variability among the genotypes for the mentioned characters and sufficient scope for development of new variety or genotypes. High genetic advances as percentage of mean were recorded for green forage yield (q/ha/day). High heritability estimates were recorded for 100-seed weight (g) and by green forage yield (q/ha). Correlation coefficient showed significant positive correlation with dependent character green forage yield with green forage yield per day at genotypic and phenotypic level. Maximum positive direct effect was obtained for green forage yield per day. These results indicate that green forage yield can be improved much better way by selection. Selection for these traits is likely to accumulate more additive genes leading to further improvement of performance of genotypes.

Authors: Hamayun Rahma , Iqbal Muhammad Shahid , Qadir Muhammad Imran
Published: September 2021

Analgesic, anti-inflammatory and anti-pyretic activities of n-hexane and aqueous ethanolic extracts of Malva neglecta in Swiss albino mice was evaluated. For each activity, the mice were divided into 4 groups: Group 1 served as control, Groups 2 and 3 were given n-hexane and aqueous ethanol extracts, respectively whereas Group 4 was treated with the standard drug. Analgesic activity was evaluated against acetic acid induced writhing, Eddy's hot plate method, and Formalin induced paw licking. Anti-inflammatory activity was evaluated by carrageenan-induced paw edema. The extracts were also examined for their anti-pyretic activities against yeast-induced pyrexia. Results showed that the n-hexane (p < 0.05) and aqueous ethanolic (p < 0.005) extracts of M. neglecta exhibited analgesic activity by reducing acetic acid-induced writhing, mean reaction time on hot plate model and formalin-induced paw licking in mice as compared to the control. The n-hexane extract (p < 0.05) as well as aqueous ethanolic (p < 0.005) extracts produced significant antiinflammatory activity as compared to the control. Both the n-hexane and aqueous ethanolic extracts revealed significant antipyretic activity (p < 0.005 and p < 0.05, respectively) in mice model. The results of the present study demonstrated that the n-hexane and aqueous ethanol extracts of M. neglecta possess analgesic, antiinflammatory and anti-pyretic activities.

Authors: Rani Neha , Prasad Nirala Ram Balak , Pal Awadhesh Kumar , Ranjan Tushar
Published: September 2021

Investigation was carried out to ascertain the genetic architecture for heat tolerance and yield components from diallel crosses in maize (Zea mays L.). The combining ability in both the normal and heat stress conditions revealed highly significant mean squares due to general combining ability (GCA) and specific combining ability (SCA) in both the direct and reciprocal crosses for all the characters except for anthesis-silking interval in normal condition of the reciprocal crosses. Estimate of components of variance for 13 characters revealed higher SCA variance than that of GCA and reciprocal crosses for all the characters. CML 411 was good general combiner for grain yield in both the conditions, whereas, CML 306 and CML 307 were good general combiners in heat stress condition, and CML 164, CML 304 and CML 305 were average general combiners in normal condition. On the basis of high yield, high SCA and at least high GCA of seed parent, the CML 411*CML 305 and CML 411*CML 307 were identified as promising hybrids for normal and heat stress conditions, respectively.

Authors: Md Kamrujjaman - , Keya Kamrun Nahar , Islam Md Shafiqul
Published: September 2021

The present study is connected to the analysis of a nonlinear system that covered a wide range of mathematical biology in terms of competition, cooperation, and symbiosis interactions between two species. We focus on how populations change their densities when two different species follow the non-symmetric logistic growth laws. We have investigated the stability of the corresponding densities of population, and to control the convergence of solutions by proper choice of interacting constant and periodic parameters. It shows the effect of crowding tolerance on both species. It will show that there exists an infinite number of coexistence solutions if the resource distributions are identical for both populations. If the carrying capacity of the first species exceeds the rest one, then eventually the second population drops down to extinction. The results are presented studying the Lyapunov functional, phase portraits, and in a series of numerical examples.

Lagrangian Relaxation Method in Approximating the Pareto Front of Multiobjective Optimization Problems
Authors: Rizvi MM , Alam HS Faruque , Ray Ganesh Chandra
Published: September 2021

In this paper, we propose that the Lagrangian relaxation approach can be used to approximate the Pareto front of the multiobjective optimization problems. We introduce Lagrangian relaxation approach to solve scalarized subproblems. The scalarization is a technique employed to transform multiple objectives optimization problems into single-objective optimization problems so that existing optimization techniques are used to solve the problems. The relaxation approach exploits transformation and creates a Lagrangian problem in which some of the constraints are replaced from the original problem to make the problem easier to solve.  The method is very effective when the problem is large scale and difficult to solve; this means if the problem has nonconvex and nonsmooth structure, then our proposed method efficiently solves the problem. We succeed in establishing proper Karush Kuhn-Tucker type necessary conditions for our proposed approach. We establish the relation between our proposed approach and the well-known existing approach weighted-sum scalarization methods. We conduct extensive numerical experiments and demonstrated the advantages of the proposed method of adopting a test problem.

The Economic Order Quantity Repair and Waste Disposal Model: Solution Approaches
Authors: Billah Misha , Rizvia MM , Das Lipon Chandra
Published: September 2021

As an inventory management instrument, Economic Order Quantity (EOQ) is gaining increased attention. EOQ has become the focus point of everyone’s interest, especially scientists. There are inventory problems in the production and repair system where the used products are collected to repair, and after repairing, it is considered as a new product. A two-stage EOQ model for manufacturing, repairing and disposing of products is discussed in our analysis. The present model follows a former model introduced by Nahimas and Rivera, where the repair system is finite. We propose a new mathematical model in reverse logistics system where demand in production and repair items follows an exponential rate. Mathematical expressions for determining the production and repair quantities are also initiated here. In this model, it is assumed that the available space for supply and repair depots is limited, and we impose two constraints that turn the problem into a constrained optimization model. We also conduct extensive numerical experiments, and advantages are addressed.

Published: September 2021

O objetivo do presente estudo foi relatar um caso de lipoma diagnosticado em um paciente do sexo masculino, 56 anos de idade, melanoderma e que apresentou lesão nodular. Este processo patológico apresentava-se assintomático, bem delimitado, de consistência amolecida, recoberto por mucosa de superfície íntegra, com coloração amarelada e média, aproximadamente, 2,5 cm. Sua evolução era de aproximadamente 4 anos e estava localizado em fundo de vestíbulo inferior entre os dentes 32 e 34. Diante dos aspectos clínicos, levantou-se a hipótese diagnóstica de lipoma. Assim, foi realizada a biópsia excisional e, em junção ao exame histopatológico do espécime removido, pôde-se confirmar o diagnóstico clínico da lesão. O paciente encontra-se há 7 meses sem sinais de recidiva da mesma. Vale destacar a necessidade da realização de anamnese criteriosa, além do conhecimento acerca dos achados clínicos pelo Cirurgião-Dentista, o que capacita e, também, proporciona uma correta conduta terapêutica da referida lesão por estes profissionais.

O presente artigo aborda sobre a produção de resíduos durante o processo de construção da centralidade do Kilamba e os impactos provocados pelo lançamento dos mesmos no ecossistema urbano. Para responder às nossas questões de pesquisa, a estratégica metodológica utilizada foi à qualitativa através do estudo de caso. O objetivo foi identificar os impactos socioambientais no ecossistema urbano de Luanda provocado pela disposição de resíduos proveniente da construção da centralidade do Kilamba. A nossa compreensão sobre o estudo de caso se baseia na perspectiva socioambiental, destacando todos os fatores que afetam os ecossistemas, assim como: contaminação do solo e do ar; comprometimento do lençol freático, disseminação de doenças devido à proliferação de vetores; e avaliação do local. Através de levantamento bibliográfico, escolha e observações, foi possível identificar que houve produção de resíduos, muitos deles tóxicos, como por exemplo, sobras de madeira de diferentes origens, tábuas, tintas, solventes e cal e foram depositados, de forma adequada. Logo, o estudo, propõe a necessidade de adoção de políticas e gestão de resíduos na construção civil e a realização de estudos na perspectiva socioambiental.

A hanseníase é uma doença crônica, causada pelo Mycobacterium leprae, que acomete a pele causando lesões. No entanto, o agente infeccioso também possui predileção pelos nervos periféricos, ocasionando o comprometimento das funções motoras quando não tratada. O diagnóstico precoce é fundamental para controle e eliminação da doença. Desta forma para uma terapia medicamentosa adequada é necessário a orientação. A presente pesquisa teve como objetivo a análise do tratamento farmacológico e não farmacológico de indivíduos com hanseníase cadastrados em uma unidade básica de saúde (UBS) da Zona Sul da cidade de Teresina, no Piauí em um período de 10 anos (2011-2021) mediante avaliação de prontuários e, consequentemente, avaliação da sua qualidade de vida e forma de adesão a terapia. O estudo tratou-se de uma pesquisa transversal documental retrospectiva de caráter descritivo, com abordagem qualiquantitativa, nas quais os dados foram coletados por meio da avaliação dos prontuários de pacientes tratados no intervalo dos anos de 2011 à 2021. Mediante os resultados obtidos, evidenciou-se a ausência do serviço de atenção farmacêutica e a sua direta contribuição para a ineficácia do tratamento farmacológico e não farmacológico para hanseníase, somado ao desconhecimento dos pacientes acerca do real conhecimento sobre a patologia – o que corroborou para a dificuldade de adesão ao tratamento, somado aos efeitos adversos passíveis de prevenção causados pela poliquimioterapia, evidenciando assim mais uma vez a necessidade do profissional farmacêutico como o responsável em conjunto pela terapia medicamentosa do paciente em tratamento para hanseníase.

Objective: to accomplish a literature review to research the clinical characteristics of azythromycin, and its indications and associations for SARS-CoV-2 infections.  Methodology: Electronic searches were carried out on PUBMED Central, BVS/BIREME, Web of Science and The Cochrane Library with the aid of key-words. Results: Azithromycin is a secure antibiotic belonging to the macrolide class, effective for a vast number of infections, especially respiratory diseases. It seems to have viral indirect activity due to its being capable of altering the cell machinery, including mitochondrias, for changing the normal functioning of mitochondrial ribosomes. Conclusion: It is uncertain whether azithromycin is eligible for the treatment of virus infections in general and especially for COVID-19. Its combination with hydroxychloroquine, however, should be better researched in order to answer if it can be applied as a clinical approach for this matter.

A infecção pelo papilomavírus humano é a causa de diversas doenças em homens e mulheres. Mais de 100 tipos de HPV são conhecidos e cerca de 30 estão relacionados à infecção anogenital, sendo a infecção viral sexualmente transmissível mais prevalente em todo o mundo. Diante do proposto, o trabalho tem como objetivo realizar uma revisão sistemática sobre o diagnóstico do HPV em homens. O estudo trata-se de uma revisão sistemática com a questão de pesquisa ‘como é realizado o diagnóstico do HPV em homens?’ Para responder a essa pergunta, foram utilizados os descritores “HPV OR papillomavirus” AND “diagnostic” AND “man OR men”, nas bases de dados do PubMed, ScienceDirect e SciELO. Após a extração dos artigos das três bases de dados e aplicação dos critérios de inclusão e exclusão, se chegou ao final com um total de 26 artigos. Dentro da revisão, foram vistos os métodos mais utilizados para a triagem de HPV masculino, como: a peniscopia, avaliação citológica e histológica, ensaios sorológicos, imuno-histoquímica de p16 e os testes moleculares que possuem grande importância no diagnóstico conclusivo, sendo relatados em 14 artigos. O genótipo mais encontrado nos artigos foi o HPV 16, tipo de HPV de alto risco, sendo mencionado em 11 estudos.  Além disso, dez enfermidades foram associadas à infecção por HPV como: câncer ou displasia anal, câncer de cabeça e pescoço, câncer peniano, coinfecções com mais de um genótipo de HPV e com vírus de HIV. O estudo foi limitado por falta de padronização metodológica dos artigos utilizados. Embora a prevalência de infecção por HPV em homens seja alta não existe consenso de quais testes devem ser usados ​​para estabelecer um diagnóstico. As diversas metodologias possuem valores de sensibilidade e especificidade diferentes, dessa forma, o diagnóstico da infecção de HPV masculino tende a associar os métodos disponíveis.

O objetivo do presente trabalho foi desenvolver e caracterizar diferentes formulações de hambúrguer vegano de grão de bico com adição de ora-pro-nóbis e verificar a aceitação dos produtos. Neste trabalho, foram desenvolvidas quatro formulações com diferentes proporções de grão de bico (Cicer arietinum L.) e ora-pro-nóbis (Pereskia aculeata Mill): Formulação 1 (100% grão de bico), Formulação 2 (95% grão de bico e 5% ora-pro-nóbis), Formulação 3 (90% grão de bico e 10% ora-pro-nóbis) e Formulação 4 (85% grão de bico e 15% ora-pro-nóbis). Foram realizadas as análises de composição proximal: umidade, proteínas, fibras, lipídeos, cinzas e carboidratos, valor energético, além das análises de atividade de água, acidez total titulável, pH e parâmetros de cor dos hambúrgueres crus e da folha de ora-pro-nóbis. Bem como análise sensorial, por meio do teste de aceitação e intenção de compra dos hambúrgueres. A adição de folhas de ora-pro-nóbis nas formulações acarretou no aumento do teor de umidade e Aw, não alterando a acidez e pH dos hamburgueres. Em relação a análise de cor, maiores porcentagens de ora-pro-nóbis nas formulações, reduziram a luminosidade dos hamburgueres (diminuição do L*), e as tonalidades vermelho (diminuição de a*) e amarelo (diminuição de b*). Em relação a analise sensorial verifica-se que as formulações com maiores notas para os atributos foram F1 e F3. Considerando os resultados, o hambúrguer com adição de 10% de folhas de ora-pro-nóbis foi o mais aceito, sugerindo maior potencial para a comercialização.

A utilização de aditivos fitogênicos na alimentação animal surgiu com a necessidade de substituição dos aditivos tradicionais e os promotores de crescimento, que foram proibidos para utilização pela União Europeia há alguns anos e no Brasil recentemente. Desde então, vários trabalhos foram realizados para diversas espécies da produção animal, de modo que atualmente os aditivos fitogênicos mais utilizados são os óleos essenciais, extratos, ervas, especiarias e frações vegetais que incluem cascas, folhas, raízes, sementes e outros. Estes aditivos são compostos por várias substâncias bioativas de natureza química variada, exercendo funções positivas sobre o organismo dos animais. Na cunicultura, são utilizadas principalmente para melhorar o funcionamento do sistema digestório, reduzir desafio sanitário e promover maior digestibilidade de nutrientes. Além de melhorar a nutrição, o consumo, estimular a digestão e o desempenho, o uso de substâncias bioativas reduz a incidência de doenças, melhora os parâmetros reprodutivos, atuam como antifúngicos, anti-helmínticos, antivirais, antimicrobianos, anticoccidianos e antioxidantes. Devido a esses benefícios, o objetivo desta revisão é abordar os diferentes tipos de compostos fitogênicos e substâncias bioativas utilizadas na produção de coelhos dando enfoque na reprodução, bem-estar e qualidade da carne.
