2. EFFECTS OF THE DIETARY SUPPLEMENTATION WITH A MICROALGA EXTRACT ON BROILER PERFORMANCE AND FATTY-ACID MEAT PROFILE
ABSTRACT The present study was carried out in the poultry sector of UNOESC Xanxerê to evaluate the effect of various inclusion levels of seaweed (Schizotrichium ssp.) in the diet of broiler chickens in terms of performance, carcass yield, organ profiles and fatty acids levels in meat. We studied 480 one-day-old Cobb chicks, distributed in a completely rando

3. Factors Affecting Broiler Production: A Meta-Analysis
ABSTRACT The meta-analysis data were obtained from a survey of published articles over 15 years. The data were selected to classify the factors that impact broiler production and separated by influence aspects of animal production (thermal environment and other factors). The relevant data for each study were systematized, grouped and later tabulated and inse

4. Phenotypic correlation of characteristics in the gilt performance test with an average number of live-born piglets through all achieved births, during the reproductive exploitation
RESUMO A eficácia reprodutiva das porcas dita o nível de rentabilidade da própria produção, e o momento do teste e seleção de leitoas para reprodução (como os pais de uma geração futura) representa um momento muito importante. Dado o fato de que a seleção de leitoas para criação é parcialmente baseada no ganho de peso no teste, neste estudo e

6. Impact of reproductive and productive rates on levels of inbreeding and genetic gain of pigs through data simulation
ABSTRACT The objective of this study was to evaluate the impact of farrowing and mortality rates on inbreeding levels and genetic gain through data simulation. Data came from two real populations A and B, composed of Pietrain and Landrace breed pigs, respectively. To generate the simulated populations, a Fortran-language simulator was developed using the (co
