| ABSTRACT In this study, the influence of carcass parts weights (thigh, breast, wing, back weight, gizzard, heart, and feet) on whole carcass weight of white turkeys (Big-6) was analyzed by regression analysis based on ridge regression and factor analysis scores. For this purpose, a total of 30 turkey carcasses of 15 males and 15 females with 17 weeks of age, were used. To determine the carcass weight (CW), thigh weight (TW), breast weight (BRW), wing weight (WW), back weight (BW), gizzard weight (GW), heart weight (HW), and feet weight (FW) were used. In the ridge regression model, since the Variance Inflation Factor (VIF) values of the variables were less than 10, the multicollinearity problem was eliminated. Furthermore, R2=0.988 was obtained in the... |

| Abstract: This study aimed to evaluate the production performance, quantitative carcass characteristics, andeconomic viability of lambs of genetic group Pantaneiro finished under four production systems:1) Stockpiled Brachiaria brizantha cv piatã pasture; 2) Consortium of sorghum intercropped with Brachiaria brizantha cv piatã; 3) Feedlot based on sorghum silage and 2% body weight energyprotein supplementation, 4) Feedlot based on sorghum silage and 4% body weight energy-protein supplementation. Were used one hundred Pantaneiro lambs with an average body weight of 17.85 ± 2.50 kg and at 70 ± 15 days of age, approximately. The average final body weight and total body weight gain of the animals finished on the consortium of sorghum intercropped with... |

| The aim of this study was to evaluate the effect of three different grazing systems: isolated, alternate and simultaneous, on feed intake, performance and carcass characteristics of sheep. About 5.2 ha area of Tanzania grass (Panicum maximun Jacq cultivate Tanzania) was divided into 13 paddocks. This area was used as a stocking rate of two animal units (AU) per ha for 7 days? occupation and 21 days rest. A total number of 58 animals were used consisting of 12 heifers and 30 Santa Ines lambs with the addition of 16 adult ewes that were used to stabilize grazing pressure in the isolated system. The sheep were fed on 200 g per head per day of concentrate and cattle 2 kg per head per day. The parameters determined were the following: weekly weight (WW), total... |

| Abstract: The objective of this study was to determine the energy value of pasta waste through a metabolism trial and determine the best level of its inclusion in broiler diets. In the metabolism trial, sixty 14-day-old birds were assigned to two treatments (control diet and a diet in which 30% was replaced by the byproduct) with six replicates and five birds per experimental unit. In the performance trial, 525 one-day-old chicks were assigned to treatments consisting of five levels of pasta waste (0, 100, 200, 300, and 400 g kg−1) in the diet, with seven replicates and 15 birds per experimental unit, in a completely randomized design. The phases of up to 7, 21, 35, and 42 days of age were evaluated. At the end, two broilers with average weight... |

| No Brasil, para atender as exigências nutricionais, as dietas para monogástricos são formuladas principalmente a base de milho e farelo de soja, entretanto estas matérias-primas apresentam alto valor no mercado, com isso, tem-se buscado alternativas para substitui-las nas dietas. Por outro lado, alimentos alternativos podem conter fatores antinutricionais, como por exemplo os fitatos que podem formar complexos insolúveis com proteínas e minerais ? reduzindo a disponibilidade destes nutrientes. O uso de enzimas exógenas nas dietas de frangos pode trazer alguns benefícios, tais como: redução na viscosidade da digesta, melhora da digestão e absorção de nutrientes, aumento no consumo alimentar, melhora ganho de peso e na conversão alimentar, diminuição do... |

| Abstract: The objective of this study was to evaluate the weight of non carcass components of lambs from genetic groups locally adapted to the Brazilian semiarid region submitted to diets with different voluminous: concentrate ratios. Twenty male lambs, not castrated, were used at approximately four months of age and average weight 18.8 ± 2.82 kg. The lambs were distributed in a completely randomized design, in a 2 x 2 factorial arrangement, composed of two genetic groups (Morada Nova and Santa Inês) and two voluminous ratios: concentrate (14.28: 85.72 and 54.96: 45, 04), making four treatments with five replications each. After skinning and evisceration, contents of gastrointestinal tract and non-carcass components (empty gastrointestinal tract, blood,... |

| Abstract: The objective of this work was to evaluate the performance of young Nellore bulls and of young dual-purpose dairy bulls fed proportions of 'Mulato II' grass silage (400 and 100 g kg-1), in diets with high levels of concentrate, as well as to evaluate the cost of this feed. Sixteen young Nellore bulls and 16 young dairy crossbred bulls were used, with initial average weight of 380.69±10.45 and 376.94±17.16 kg, respectively, and average initial age of 24 months. A completely randomized experimental design was carried out in a 2x2 factorial arrangement. The highest silage proportion caused a 13% increase in dry matter intake (percentage of body weight) and a 19.7% decrease in dry matter digestibility of the diet, but it did not alter the intake of... |

| ABSTRACT The objective of this study was to evaluate the production performance of feedlot cattle fed diets containing chopped sugarcane ratios (580 or 380 g/kg of diet dry matter) as roughage and levels of inclusion of babassu mesocarp bran (BMB; 420 to 620 g/kg of concentrate dry matter). Twenty-four young Nellore bulls with 321±23 kg initial body weight, at 22 months of age, were used in a completely randomized experimental design with treatments in a 2 × 2 factorial arrangement and six replicates. Dry matter intake (21.71 g/kg of body weight), average daily gain (1.46 kg/day), and cold carcass weight (232.59 kg) were not changed by proportion of sugarcane or BMB level. The proportions of sugarcane and BMB levels did not change the apparent... |
