The objective of this study was to evaluate the characteristics of carcass and weight of the commercial meat cuts from carcass of Red Norte and Nellore young bulls finished in feedlot. Forty four animals – 22 Red Norte with initial average weight of 367±30 kg and 22 Nellore at initial average weight of 361±30 kg – were used. The animals received feed ad libitum with concentrate:roughage ratio of 50:50 during 112 days, from which 28 days were for adaptation. Red […]

This experiment evaluated carcass traits and yields of comercial cuts and tissue evaluation of 20 Morada Nova lambs fed diets with fruit-refuse of melon replacing 0, 30, 60 or 100% of ground corn. The animals with 15 kg of initial body weight and at 6 six months of age were kept confined in individual pens and slaughtered with 26 kg of weight. It was used a completely randomized experimental design, with four treatments (levels of ground corn replaced by melon […]

The objective of this study was to evaluate the effect of supplementation on the carcass characteristics of crossbred Boer goats finished on native pasture. Twenty-four Boer crossbreed goats were used, 120 days old and with an initial 15.52 kg BW. The supplemental feeding was randomly assigned to the animals according to a completely randomized design with 4 supplementation levels (0.0, 0.5, 1.0 and 1.5%) and six replications (goats). The animals had access to the pasture from 7:30 a.m. until 4 […]

This experiment aimed to simulate thermal-stress-environment conditions in climatic chamber during the transportation of birds to slaughterhouse to evaluate the influence of these conditions on physiological parameters and carcass conformation in broiler chickens. Thirty chicks with 42 days old were weighted and distributed to transportation crates (10 chicks by crate), and submitted to high stress conditions (35ºC and 85% RH) to simulate the transport to the slaughterhouse. At each time of exposition to the stress conditions (0, 30, 60, 90 […]

The study aimed to evaluate the performance and carcass yield of four quail genetic groups male and females. The birds were grown until 42 days old. A thousand and two hundred day old quails were distributed in a completely randomized design with four treatments (A, B, C and D) and five replicates of 60 birds each. The birds were weighed once a week in order to evaluate weight gain and feed consumption. Mortalities were recorded daily. At 42 days, ten […]
