title: The Effect of Different Levels of Lentil by Product on Growth Performance, Carcass Traits and Egg Yield in Quail (Coturnix Coturnix Japonica)

description: ABSTRACT The subject of this study was to evaluate the effects of lentil byproduct (LP) on growth performance, carcass traits and egg yield of quail (Coturnix coturnix Japonica). To achieve this goal, a total of 600 0-day-old quail chicks were used. The birds were divided into 5 groups with 3 replicates. The 1st, 2nd, 3rd, 4th and 5th groups received 0, 5, 10, 15 and 20% lentil byproduct, respectively. All the diets were prepared as isonitrogenous and isocaloric. As a result of this study, the highest live body weights of quails as Laudadio mixed gender were observed in the 3rd (195.5 g) and 5th (195.3 g) groups at the end of the study, however the differences between the control and treatment groups were not significant (p&gt;0.05). Similar results were observed in the carcass traits, as well. The best feed conversion ratio (FCR) was noted in both the 2nd and 3rd groups as 3.04 and it was significantly (p&lt;0.05) different than in the control and other treatment groups. The least feed intake (FI) was observed in the 2nd group. The highest and the lowest egg yield percentages were in the 3rd (90.78 %) and 5th (66.57 %) groups, and differences were significant (p&lt;0.01). Linear increments were observed in the yolk color when LP increased in the diet. As a result, it could be concluded that lentil by product could be added into quail diets up to 15% with no negative effect on live body weight (BW) and carcass traits and to get better yolk color.

title: Protocol with nine days of progesterone for fixed-time artificial insemination in Bos taurus cows adapted to the tropical weather

description: ABSTRACT Three experiments were performed to adapt a synchronization protocol of estrus synchronization and ovulation to be used in fixed time artificial insemination programs (FTAI) in tropically adapted Bos taurus cows. In Exp. 1 (crossover) multiparous Curraleiro Pé-Duro cows (n= 12) received an intravaginal device containing 1g of P4 for 8 days and 2mg of EB at the time of device insertion (Day 0). On the P4 device removal (Day 8) females received 150g of D-cloprostenol Sodic and 300IU of equine chorionic gonadotropin (eCG). Then, they were randomly divided to receive 1mg of EB on Day 8 (EB8) or on Day 9 (EB9). EB9 delayed ovulation approximately 15 hours (P&lt;0.05). In Exp. 2, protocols using progesterone for eight (P4D8) or nine days (P4D9) were evaluated, resulting in similar parameters of folicular and luteal development (P&gt;0.05). In Exp. 3, EB8 and P4D9 protocols were used to evaluate the pregnancy rate, reaching 23% (10/43) and 20% (9/45), respectively (P&gt;0.05). Although P4D9 protocol has shown improvement in proportion of animals that responded to the protocol when compared to EB8 protocol, it was not able to improve pregnancy rate.

title: Identifying microorganisms related to copper bioleaching at 35 and 50°C

description: ABSTRACT Bioleaching is an alternative to pyrometallurgy for the production of metals from low-grade ores containing high level of impurities, once that live pyrometallurgical methods are economically unfeasible. The quantification and identification of those microorganisms related to bioleaching is an important strategy for process control and thus metal recovery. In this regard, molecular biology is one of the main techniques utilized for such objective. This study applied PCR, RFLP and PCR-DGGE techniques to show that the microbial diversity in copper bioleaching columns under investigation is low and the temperature is important to define the species found, with predominance of Acidithiobacillus ferroxidans, at 35°C and Sulfobacillus thermosulfidooxidans at 50°C.

title: Biofloc production in activated sludge system treating shrimp farming effluent

description: ABSTRACT The release of wastewater and the shrimp feed cost are the main challenges faced by the shrimp farming industry. An alternative solution to both problems is biofloc production in a unit external to the farm, in an activated sludge system for effluent treatment. The treatment system’s influent was composed of the shrimp farm wastewater supplemented with urea and sugarcane molasses. The results show that the average removal of chemical oxygen demand was 71% and the average biofloc production in the reactor was approximately 1.5g.L-1. Adding molasses to the influent contributed to the increase in the quantity and diversity of existing microorganisms that are beneficial to cultured shrimp. The mass balance of nitrogen compounds confirmed that nitrification occurred in the system. Therefore, the use of the activated sludge system is a viable and environmentally suitable alternative to produce bioflocs and shrimp farming effluent treatment.

title: SIMULATION OF SODIUM AND POTASSIUM DYNAMICS BY THE HYDRUS 2D MODEL IN A HAPLIC PLANOSOL VIA RESIDUE WATER

description: ABSTRACT The application of chemical substances to the soil together with little attention given to the possible environmental impacts, transformed the environment into a recipient of waste. The aim of this study was to simulate the movement of water and solutes (sodium and potassium together) using the STANMOD and HYDRUS-2D models in a typical Haplic Planosol under the application of wastewater via surface irrigation under different flow rates. The experiment was conducted in the laboratory by miscible displacement tests, first using columns with deformed soil under saturation and steady water flow conditions, at a rate of 11.7 cm3 min-1, to obtain transport parameters of sodium and potassium ions, and in the applied residual water, the values of 475 and 76.6 mg dm-3, respectively. The transport parameters were estimated from the numerical adjustment of effluent distribution curves, using the STANMOD model. In a second step, the HYDRUS-2D model was applied to simulate the volumetric soil moisture distribution profiles, as well as the ion concentrations in the wet bulb. Considering the results obtained, we can see that there was considerable interaction between the solutes and the soil. The value of the delay parameter was higher for the sodium when compared to the potassium, reflecting its greater adsorption and the processes of exchange between the solute and the soil. The results suggested the need for adequate soil management in order to avoid future soil sodification and, in view of the application of HYDRUS-2D, it was verified that the model presented a satisfactory performance in the simulation of the displacement of the ions, after 1, 5 and 10 hours of wastewater application.

title: Climate Change in Layer Poultry Farming: Impact of Heat Waves in Region of Bastos, Brazil

description: ABSTRACT The region around the municipality of Bastos, state of São Paulo, accounted for about 7% of Brazilian egg production in 2015. In 2012, it experienced a heat wave that resulted in the death of approximately 500,000 hens, according to information released at the time. Considering the impact of heat waves on layer mortality, the objective of this study was to analyze how heat waves impact the layer farming in the region of Bastos, considering the climate change scenarios forecasted by the IPCC for the next years. This study was conducted in three stages: i) analysis of the IPCC reports to understand climate change scenarios; ii) analysis of historical temperature data in the region of Bastos; iii) analysis of how climate change, through heat waves, may impact layer mortality in this region. All the IPCC scenarios indicate that both average temperature and the number of extreme events, such as heat waves, are expected to increase. Historical data showed that since the mid-1980s, maximum temperature has increased, as well as the frequency, intensity and duration of heat waves. The association of layer mortality due to heat waves with the IPCC climate change forecasts for that region indicates a trend of increasing layer mortality in egg production operations which sheds are not equipped with air conditioning.

title: Slaughter and Carcass Traits of Geese with Different Feather Colour and Gender

description: ABSTRACT The aim of this study was to determine slaughter and carcass traits of geese with different feather colour and gender. The study was conducted with Turkish geese in free-range production conditions in Kars, Turkey. A total of 282 geese (251 females, 31 males) were grouped by feather colour as black (n=49), white (n=77), black pied (n=127), and brown and brown tawny (n=29). Geese were weighed before slaughter and then the slaughter and carcass traits were determined. Data were subjected to one-way ANOVA, and post-hoc Tukey HSD test was applied to compare feather-colour means and the independent sample t-test was used to compare gender means. Feather colour did not influence (p&gt;0.05) slaughter and carcass traits, except for hot carcass, feather and heart percentages (p&lt;0.05). Males showed statistically higher feet (p&lt;0.001), heart (p&lt;0.01), liver (p&lt;0.05) and gizzard (p&lt;0.01) weights compared with females, as well as significantly higher (p&lt;0.05) feet, heart, liver and gizzard yields. In conclusion, feather colour did not influence the evaluated slaughter and carcass characteristics of geese reared under semi-intensive conditions in the province of Kars, Turkey, and higher feet, heart, liver and gizzard weights and yields were obtained in males than in females.

title: Establishment of a Pathogenicity Index for Mice to Pasteurella multocida Strains Isolated from Poultry and Swine

description: ABSTRACT Fowl cholera is a contagious disease that results from infection by the bacterium Pasteurella multocida. This microorganism is extensively distributed among animal species, but little is known regarding it’s pathogenesis and specificity to various hosts. Many studies using pathogenicity evaluation methods are subjective and difficult to quantify because they are often only involved in the observation of the lethal capacity of the agent in experimental inoculation. Due to a lack of more consistent data, this study aimed to establish a classification model of P. multocida pathogenicity in mice using strains isolated from poultry and swine. A total of 94 strains of P. multocida isolated from clinical cases of FC and from lungs of swine were tested. A volume of 0.1 mL of bacterial suspension was obtained from the concentration of 106 CFU/mL and inoculated by an intraperitoneal route in five mice. The animals were observed every six hours over seven days. In addition to the mortality observed, the time of death and gross lesions were also analyzed. The Pathogenicity Indexes obtained showed significant differences (p&lt;0.05) according to the origin of the strains. Likewise, the number of gross lesions and isolation percentages were also varied (p&lt;0.05) among strains isolated from poultry and swine. From the observed ratios, the isolates were grouped into three pathogenicity classes: high, medium and low. This study proposed a consistent measurement and classification of P. multocida pathogenicity. The obtained results will be used to generate other adjusted models, as well as to form the basis for disease diagnosis.

title: Molecular Authentication of Meats from Three Terrestrial Birds Based on Pcr-Rflp Analysis of the Mitochondrial 12S rRNA Gene

description: ABSTRACT In this study, a method utilizing PCR-restriction fragment length polymorphism (PCR-RFLP) of a mitochondrial gene was developed for the identification of chicken (Gallus gallus), quail (Coturnix coturnix), and common pigeon (Columba livia) meat. PCR products of ~440 bp were obtained from the 12S rRNA gene of these three birds using a pair of universal primers. The three terrestrial birds can be distinguished using one restriction endonuclease, Alu I, which was selected based on species-specific variations in the mt 12S rRNA gene sequence using 9 newly-obtained and 44 published chicken, quail and pigeon sequences. This method was also successfully used to identify commercial quail and pigeon meat products, which were found to be adulterated with chicken meat. Additionally, our method had relatively high sensitivity for detecting a meat mixture. Ten percent of chicken meat in the mixed quail and pigeon sample was detectable. This assay can be useful for the accurate identification of meats from terrestrial birds, avoiding mislabeling or fraudulent species substitution in meat products.
