Inceptisols merupakan ordo tanah yang tersebar luas di Indonesia. Lahan Inceptisols menjadi pilihan yang potensial untuk kegiatan pertanian karena luasan totalnya yang cukup besar. Salah satu kendala dalam pemanfaatan tanah Inceptisols ialah sifatnya yang kurang subur dengan kandungan nitrogen (N) yang rendah. Solusi dari permasalahan tersebut salah satunya ialah pengaplikasian bakteri endofitik penambat N. Penelitian ini dilakukan dengan tujuan untuk menganalisis pengaruh inokulasi tiga jenis bakteri endofitik penambat nitrogen (Gluconacetobacter diazotrophicus corrig (GD1), G. diazotrophicus VTH-Ai80 (GD2), dan Paraburkholderia, sp.) dengan tiga teknik aplikasi yang berbeda (perendaman benih, penyiraman tanah, dan kombinasinya) terhadap pertumbuhan tanaman, populasi bakteri endofitik, dan bobot kering tanaman tomat pada tanah Inceptisols asal Jatinangor. Penelitian dilaksanakan di Rumah Kaca Percobaan Bale Tatanen dan Laboratorium Biologi Tanah Departemen Ilmu Tanah dan Sumber Daya Lahan, Fakultas Pertanian, Universitas Padjadjaran Jatinangor, Kabupaten Sumedang, Jawa Barat pada bulan Oktober s.d. Desember 2023. Rancangan percobaan yang digunakan yaitu Rancangan Acak Kelompok (RAK) yang terdiri 10 kombinasi perlakuan dengan 3 ulangan dan 3 subsampel. Hasil penelitian menunjukkan bahwa pemberian bakteri endofitik penambat N dengan teknik aplikasinya berpengaruh nyata pada tinggi tanaman 1 MST dan bakteri endofitik bagian akar, tetapi tidak berpengaruh nyata pada pengamatan lainnya. Perlakuan G. diazotrophicus VTH-Ai80 + Perendaman Benih + Penyiraman Tanah merupakan perlakuan yang lebih baik dalam meningkatkan tinggi tanaman 1 MST. Perlakuan G. diazotrophicus corrig + Penyiraman Tanah merupakan perlakuan yang lebih baik dalam meningkatkan populasi bakteri endofitik pada bagian akar tanaman tomat.

Purpose: to study the effect of vitamin C and MEK Feedbest®VGPro when introduced into the compound feed of broiler chickens with excessive background of heavy metals on the indices of meat productivity, food and biological value, ecological safety of their meat.Materials and methods. The objects of the study were meat chickens of the ROSS-508 cross. At the age of one day, 4 groups of 100 birds each were formed from them in accordance with the principle of analog groups. In the composition of the used recipes of complete compound feed in all three age periods of growing, the main grain and protein ingredients were represented by locally produced feed: corn, wheat, peas and rapeseed meal. Growing of experimental broilers for meat was completed at the age of 42 days and their control slaughter was carried out, for which 5 birds were selected from each group. The concentration of salts of heavy metals was determined in the samples of feed and meat of the experimental birds.Results. The experiment substantiated the feasibility of combined introduction of MEC Feedbest®VGPro at a rate of 100 g/t of feed and vitamin C at a rate of 500 g/t of feed into diets with excessive content of heavy metal salts. Compared to the control analogues, broilers of the 3rd experimental group showed a reliable (p<0,05) decrease in fat by 0,26 % and a simultaneous increase in dry matter, protein and the value of the protein-quality indicator in the pectoral muscle samples. Combined additions of the tested preparations contributed to a decrease in the concentration of zinc by 63,17 % (p<0,05), cadmium by 61,11 % (p<0,05) and lead by 62,34 % (p<0,05) in poultry meat samples from the 3rd experimental group, compared to the control. Moreover, in the meat samples of broilers of the 3rd experimental group, the maximum permissible concentrations of none of these elements were exceeded.

Purpose: to evaluate the effect of a vitamin-mineral complex with a probiotic on the histological structure of the gastrointestinal tract tissues of budgerigars in dynamics.Materials and methods. The object of the study were budgerigars aged from 60 to 180 days. According to the principle of pairs-analogues, 3 experimental and a control group of 20 birds each were formed from clinically healthy budgerigars. For the purpose of the experiment, complete granules were created containing a basic grain-seed diet and a complex consisting of a probiotic, vitamins and minerals. Bacillus Subtillis 5 mg per 100 g of live weight was used as a probiotic. For histological and histochemical studies, tissue pieces measuring 0.5 x 0.5 x 0.5 cm were selected. In each section, an assessment of at least 10 fields of vision was given.Results. As a result of the experiment, lasting 45 days, a gradual increase in the probiotic mass was noted in the gastrointestinal tract of budgerigars on the 15th and 30th day. Complete release of the body from the probiotic was observed on the 30th day after stopping the administration of the granulated complex. No changes in the histological structure of the liver were revealed. Positive changes in the intestine and stomach were noted, such as an increase in the density of villi and the height of the epithelium, folds, crypts and tubular glands. These changes are reversible, due to the temporary effect of the vitamin and mineral complex with a probiotic.

Authors: Bakoev N. F. 
Published: November 2024

Purpose: to identify CNV regions (CNVRs) and identify potentially specific CNVs in Sal sheep.Materials and methods. The research was carried out on 48 Salsk breed sheep. Genotyping was performed using high-density microarrays Ovine SNP 600 K BeadChip array (Illumina, USA). DNA copy number variation (CNV) searches were performed using PennCNV software based on the Oar_v3.1 reference genome.Results. We identified 4585 autosomal CNVs in 48 Sal breed sheep. The average CNV length was 92,3 Kb. 21,1 % of the total number of CNVs are less than 50 Kb in size. On average, from 65 to 138 CNVs were identified per animal. 527 autosomal CNVRs were obtained, representing 54,77 Mb of the entire sheep genome. The proportion of chromosomes covered by CNVR varies by chromosome, from 0,5 % on OAR25 to 9 % on OAR24. Analysis of CNVR in the ENCEMBL system revealed 42 genes in which CNVRs are localized; the remaining CNVRs are located in intergenic regions. Comparison of the identified CNVRs with sheep QTLs from the Animal QTL database showed that 39,24 % of the genes were responsible for reproductive traits, and 20,25 % were responsible for wool-related traits.Conclusions. Functional annotation of CNVRs localized in genes and intergenic spaces was carried out and the total number of detected CNVRs in the QTL database was analyzed. The results showed that CNVs are localized in genes associated with selection-significant traits in sheep.

Authors: Elokhin E. , Turlova Yu. 
Published: November 2024

Providing the population with quality food products is currently relevant. High-tech production of meat and dairy products requires breeding animals with high genetic potential. The main role is given to bull sires, since they are responsible for the constant reproduction of the breeding stock, which depends on the non-stop renovation of the herd with high breeding value’s calves. Management of growing and breeding of young bulls can directly affect the reproductive function of sires and the physiological health. The article provides analytical data based on literary sources containing research by various authors on this topic, and reviews methods and technologies for keeping breeding bulls on various farms in the Russia and abroad. Currently, there is a many problems of getting high-quality breeding young bulls to an artificial insemination center. Currently, there are problems with obtaining high-quality breeding bulls of the enterprise. There are animals with abnormal development of the musculoskeletal system, joints, hooves, with signs of osteomalacia, etc. Such animals require additional costs for veterinary and breeding services. The quality of the sperm products they produce often does not comply with state normative. The reason is related either to the choice of maintenance technology or feeding technology. It is necessary to competently organize management, breeding and veterinary work in farms that are purposefully engaged in breeding young animals.

Purpose: zootechnical characteristics of the developing lines of Yakut breed stallions in the breeding farm "Agricultural production cooperative "Tonor" of the Oymyakon ulus of Yakutia.Materials and methods. The study of the exterior indicators of the stallions was carried out by taking body measurements according to the instructions of the All-Russian Research Institute of Horse Breeding. The use of genotypic assessment methods for animals along with classical zootechnical assessment methods for pedigree, productive traits (live weight and meat productivity of offspring, milk production, fertility of daughters) was supplemented by the use of the method of selecting offspring based on their adaptability to herd conditions.Results. Long-term selection work in the breeding farm of the Oymyakon ulus is completed by the formation of six lines of outstanding Yakut breed stallions. In terms of live weight, both stallions and mares of the Oymyakon horse surpass stallions and mares of the Yana, Kolyma and indigenous types. Oymyakon stallions (n=20) weighed on average 483,7±3,55 kg, while stallions of the indigenous types weighed 446,3±4,75 kg (n=34), Kolyma types 449,1±3,42 kg (n=87) and Yana types 469,4±3,27 kg (n=128). Oymyakon horse mares (n=165) also surpassed mares of the indigenous type (401,6±2,00 kg (n=341)), Kolyma type (432,2±1,13 kg (n=1063) and Yang type (431,0±1,16 kg (n=881)) in average live weight of 453,8±2,19 kg. According to measurements of head, neck, chest, croup, occiput and withers, chest and croup width and their indices, Oymyakon horse stallions and mares are practically no different from indigenous type horses. The founder of the line with the most numerous followers is the outstanding stallion Kyurzhet, born in 1946. He came from local Yakut horses of the former Bolshevik collective farm. His line continues on the Tonor farm through his two descendants: his grandson Chalay, born in 1981, live weight 515 kg, and his great-grandson Tenkelekh, born in 1992, live weight 490 kg. The farm produced Kyurzhet's great-great-great-grandson Chalay and 6 great-great-great-great-grandchildren, and now produces 11 continuers of the line (3 great-great-great-great-grandchildren and 8 great-great-great-great-great-grandchildren), a total of 18 continuers of his line have been and are being produced.

Published: November 2024

Purpose: determination of the adsorbent toxin and antioxidant vitamin C on the digestibility and assimilation of nutrients in the composition of compound feed for broiler chickens with a tolerant level of aflatoxin B1.Materials and methods. The objects of the study were broiler chickens of the KOBB-500 cross. When setting up the experiment, the duration of 42 days, 4 groups of 100 heads each were formed from day-old chickens according to the principle of analog groups. The experimental birds were fed complete compound feeds (CF) based on corn, sorghum and fodder beans. The samples of compound feeds have a high chemical composition and the presence of mycotoxins. Upper limits of permissible concentrations (ULC) for aflatoxin B1 were established in all three types of feed grain. Therefore, they were mixed with safe mycotoxin additives using dispensers in the feed shop of the poultry enterprise. In this way, tolerable levels (no more than 0,25 mg/kg of feed) of the content of this mycotoxin in the composition of the PK fed to the experimental birds were achieved. Against the background of the conducted scientific and production experiment with the use of chromium oxide in the composition of compound feed (as an inert indicator) on chickens (aged 35-42 days) of comparable groups (5 heads from each group), we conducted an exchange (physiological) experiment. Based on the results of chemical analysis of the fed compound feed and excrements in the droppings of the experimental birds, the level of digestibility and assimilation of nutrients in the diet was calculated.Results. During the experiment, the leadership of the combined introduction of the adsorbent toxfin in the amount of 1500 g/t and ingredient C in the amount of 500 g/t of feed into complete feeds for broiler chickens with a tolerant level of aflatoxin B1 was established. As a result, compared to the birds of the control group, the chickens of the 3rd experimental group had significantly (р<0,05) higher coefficients of digestibility of dry matter by 3,66%, organic matter by 3,90 %, crude protein by 3,63 %, fiber by 3.06% and NFE by 3,19 %, respectively. In terms of the degree of nitrogen assimilation (60,45 %), the result (51.45 %) and phosphorus (49,67 %) from the generally accepted amount with feed, the best indicators were also obtained in broilers of the 3rd experimental group, which reliably (р<0,05) outperformed their control indicators for these indicators by 3,74 %, 2,91 % and 2,45 %, respectively.
Personality Traits and Entrepreneurial Intention: A Study of Business Student Perspectives
Authors: Puskar Prasad Pokharel  
Published: November 2024

This study examines the key personality trait factors such as Need for Achievement, Innovativeness, Risk Tolerance and Self-efficacy have an influence on Entrepreneurial Intention among Management Students with moderating effect of entrepreneurship education. Data were collected from 410 MBS students of constituent colleges of TU; 4th semester students (with entrepreneurship course) and 1st semester students (without entrepreneurship course). The obtained data were analyzed using One-way ANOVA, Correlation Coefficient and Multiple Regression Analysis. The study revealed that the Need for Achievement and Self-efficacy has a significant positive relationship with entrepreneurial intention. Among the four personality trait factors (Need for Achievement, Innovativeness, Risk Tolerance and Self-efficacy), the study revealed that students risk taking propensity interacts with education. Therefore, the study depicted that entrepreneurship education does not have a positive moderating effect on other personality trait factors except risk tolerance. Similarly, the One-way ANOVA results depicted that gender, age group, colleges, entrepreneurship education (Semester) and Parent’s Profession has no statistically significant difference in terms of entrepreneurial intention. These findings suggest that MBS students of constituent colleges of TU have shown only two personality traits factors (need for achievement and self- efficacy) that have influence on entrepreneurial intention. The results of the study may have insightful implications for researchers, university educators and policy makers.

Authors: Indira Shrestha  
Published: November 2024

The dedication of employees to the organization is a significant component in determining its overall health. Additionally, the demographic makeup of the workforce influences the degree of commitment. So considering the situation the study examined the how demographic factors affect the level of commitment towards their organization. The population of the study was employees working in restaurant situated in Lalitpur district of Bagmati Zone. One hundred and fifty-four restaurant workforce were taken as the sample for the study. Convenience sampling was used to gather the information regarding organizational commitment from concerned respondents. Valid organization commitment questionnaire OCQ was employed to test the organizational commitment of restaurant workforce. The analytical research design was used to examine the influence of demographic factors. The statistical test used in the study were percentage frequency, independent sample t test and one-way ANOVA. The internal consistency of the OCQ was found reliable with Cronbach alpha (α = 9.33). The result revealed that only two demographic factors (income, job position) were found to be influencing factors for determining organizational commitment level. The remaining factors (like age, marital status, service years, education, gender) did not seem important factor to affect the organizational commitment. So the owner of the restaurants will get benefit form the result of the study and stay focused on the how income and their promotion can be important for getting committed employees in the organizations. Regarding limitation of the study, area coverage is small so future researcher is suggested to go beyond this area to make their result generalizable.
