| Differences among dietary protein levels suggested in the literature point out to the need for better evaluation of protein requirements of growing lambs, raised in drylot on a high-concentrate diet. This study evaluates the influence of crude protein (CP) levels in high concentrate diets on performance and carcass traits of ram lambs, confined for 56 days. Forty eight (48) Santa Ines lambs (initial body weight 18.4 ± 0.4 kg; 86 ± 2 days old) were fed 4 experimental diets containing 14, 16, 18 or 20% CP, in a completely randomized block design. Diets consisted of 80% concentrate and 20% sugarcane bagasse. There were no differences in average daily gain: values of 228, 220, 230 and 231 g d-1 were obtained for diets containing 14, 16, 18 and 20% CP,... |

| ABSTRACT: Owing to the lack of information in the literature about the ideal feeding frequency adopted by feedlot systems, this study was designed to evaluate the effect of different feeding frequencies on performance, carcass traits, feeding behavior and rumen morphometrics of Nellore cattle. Forty-eight yearling bulls were housed in individual pens with an average initial body weight of 358.2 kg. The experiment was designed as a completely randomized block and the treatments were the feeding of cattle one, two, three, or four times daily (n = 12 per treatment). Orthogonal contrasts were used to assess linear, quadratic and cubic relationship between feeding frequency and the dependent variable. As feeding frequency increased, final body weight (p = 0.03)... |

| ABSTRACT: Growth hormone (GH), insulin-like growth factor 1 (IGF1), and leptin (LEP) can be candidate genes for association studies because they play vital roles in the metabolism process. Thus, this study aimed to identify variants in these genes associated with body traits in Santa Inês sheep. The following were recorded: body weight at 100 (BW100) and 240 days (BW240), average daily gain (ADG), withers (WH) and croup (CH) heights, body length (BL), thoracic (TG) and leg (LG) girths, thoracic (TW) and croup (CW) widths, body depth (BD), rib eye area (REA), fat thickness (FT), and carcass finishing score (CFS). Single-locus association analysis was performed with 11 variants in IGF1, 18 in LEP, and 16 in GH. Moreover, two haplotypes in IGF1 and one... |

| O presente trabalho objetivou avaliar o uso de ractopamina em diferentes níveis de inclusão na dieta para suínos em terminação. Foram utilizados 50 suínos híbridos comerciais com peso inicial de 74,08 (1,42) kg, aleatoriamente distribuídos em cinco blocos casualizados. Havia dois animais em cada parcela experimental, macho e fêmea, alimentados com dieta suplementada com ractopamina (0, 5, 10, 15 e 20 ppm) durante 28 dias. Foram avaliados desempenho e características de carcaça dos animais. A ractopamina melhorou o desempenho, espessura de toucinho, profundidade, área de olho de lombo e rendimento de carne na carcaça, porém sem influenciar no consumo de ração, rendimento de cortes e qualidade da barriga. Exceto a dose de 0 ppm, não houve diferença entre as... |

| Abstract The objective of this study was to estimate variance components for performance and carcass traits in a paternal broiler line. The (co)variance components were estimated by the restricted maximum likelihood method applied to the animal model, including the fixed effect of group (sex and hatch) and additive genetic and residual as random effects. Estimated heritability for performance traits ranged from 0.09 to 0.42. The genetic correlations between traits ranged from -0.50 to 0.97. The heritability estimates of feed intake, weight gain, and feed conversion from 35 to 41 days of age were of low magnitude. The genetic correlations among them were favorable to genetic selection. These results suggest that moderate genetic gain can be obtained to the... |

| The purpose of this study was to determine how feeding sheep coffee pulp affects carcass characteristics and what changes occur in physicochemical, antioxidant capacity and oxidation of the meat during refrigerated storage. The experiment was carried out in 15 Blackbelly lambs weighing an average 22.86±0.76kg. The animals were assigned to three treatments: T0=control diet, T1=diet with 8% coffee pulp, and T2=diet with 16% coffee pulp. After fattening for 56 days, the sheep were slaughtered and the carcasses assessed. The inclusion of 16% coffee pulp in the diet increased carcass dressing from 48.19 to 50.83% and decreased the amount of fat in rumen and intestines from 3.43 to 2.53% (P<0.05). The inclusion of coffee pulp in the diet did not alter the... |

| We evaluated the inclusion of peeled-mango waste meal as a source of carbohydrate in the protein:carbohydrate ratio (CP:CH) on performance and chemical composition of pacamã (Lophiosilurus alexandri) juveniles. One hundred and fifty fish (11.31±0.96g) were stocked in sixteen 500 L tanks, fed three times daily (10% of live weight), in a system with water recirculation with biofilter. The treatments consisted of four experimental diets with decreasing levels of the ratio between crude protein and carbohydrate (1.40, 0.94, 0.56 and 0.29), with four replications per treatment. At the end of 60 days, we evaluated animal performance (final average weight gain, specific growth rate, total apparent feed intake, carcass yield, survival) and physicochemical... |

| Abstract Fishburgers were made with washed mechanically separated meat (MSM) from carcass and filleting by-product (both washed and unwashed) of the Nile tilapia. The proximal composition of fishburgers was different and varied according to the raw material used, as well the color parameters. Fishburgers with MSM from filleting by-product had lower hardness and springiness, and fishburger with MSM from unwashed filleting by-product had higher yield and lower reduction in thickness. The fishburgers containing MSM from filleting by-product had better sensory acceptance, due to higher color intensities (sensory), fish odor, tenderness, succulence, cohesiveness and fish flavor. The fishburger with MSM from washed carcass was the least acceptable, because of... |

| The objective of this study was to determine the metabolizable energy (ME) requirement for starting barrow pigs. Forty-three animals, selected for their high lean gain, were allotted in a completely randomized block design, divided in four treatments with five blocks and two animals in each experimental unit. The diet in Treatment 1 consisted of 3,264 kcal of ME/kg containing 0.96% of digestible lysine, 0.55% of digestible methionine+cystine, 0.60% of digestible threonine, and 0.188% of digestible tryptophan reaching the ideal protein pattern. The diets in Treatments 2, 3, and 4 were similar to the diet in Treatment 1; nevertheless, the levels of ME in Treatments 2, 3, and 4 were 2, 4, and 6% higher than those in Treatment 1. The lysine:ME ratio, was... |

| Clostridium perfringens is an anaerobic Gram-positive bacterium known as common pathogen for humans, for domestic and wildlife animals. Although infections caused by C. perfringens type C and A in swine are well studied, just a few reports describe the genetic relationship among strains in the epidemiological chain of swine clostridioses, as well as the presence of the microorganism in the slaughterhouses. The aim of the present study was to isolate C. perfringens from feces and carcasses from swine slaughterhouses, characterize the strains in relation to the presence of enterotoxin, alpha, beta, epsilon, iota and beta-2 toxins genes, using polymerase chain reaction (PCR) and comparing strains by means of Pulsed field gel electrophoresis (PFGE).... |

| ABSTRACT: The purpose of this study was to evaluate net energy and dietary ractopamine levels for barrows weighing 70 to 100kg. The 150 pigs investigated (initial weight 70.80±3.84kg) were distributed in a randomized block design with a 5×3 factorial arrangement, comprising five levels of net energy (2,300; 2,425; 2,550; 2,675; and 2,800Kcal kg-1 of diet) and three levels of ractopamine (5, 10, and 20ppm kg-1 of diet), with five replicates, and two animals per experimental unit. No interaction (P>0.05) was observed between net energy and ractopamine levels. Increasing the dietary net energy levels led to a linear reduction in feed intake, with a linear improvement in feed conversion. Net energy levels had no observable effect (P>0.05) on weight gain,... |

| ABSTRACT: This study aimed to identify the principal components (PC) that explain the highest percentages of total variance and best characterize the in vivo and carcass morphologies of Anglo-Nubian crossbred goats. Nineteen carcass morphometric traits and six in vivo morphometric traits were measured in 28 kids at eight months of age. Principal component analysis indicated that five PC were able to explain 83.57% of the total variance in the 19 original carcass traits. Those components were termed PC1-Carcass Size, PC2 - Body Condition, PC3-Carcass Width, PC4-Chest Depth, and PC5 - Hindquarter. For in vivo morphometric traits, the first two principal components explained 78.86% of the total variance. These components were called PC1-In vivo Size and... |

| The experiment was conducted to evaluate five nutritional plans based on sequences of standardized ileal digestible lysine: 0.90-0.80-0.70, 1.00-0.90-0.80, 1.10-1.00-0.90, 1.20-1.10-1.00, and 1.30-1.20-1.10% fed to gilts from 60 to 99, 129 to 100, and 130 to 148 days of age, respectively. Eighty commercial hybrid gilts, selected for lean gain, with initial weight of 23.46±0.27kg were allotted in a randomized block design, with five treatments, eight replicates, and two pigs per experimental unit. No effect (P>0.05) of the nutritional plans was verified on daily feed intake, daily weight gain and feed conversion. The nutritional plans had no influence (P>0.05) on any of the carcass traits evaluated (carcass yield, meat amount, and meat yield). The... |
