ABSTRACT The present study investigated the impacts of additional feeding (AF; containing 16% excess feed than control diet in the last two weeks of gestation) during late gestation period and different backfat thickness (BFT) including low (<20 mm) and high (≥20 mm) backfat on reproductive performance, litter size, blood metabolites, hormonal profiles, colostrum, and milk composition of sows from day 90 of gestation to farrowing, and from farrowing to weaning during summer (average 28.3 °C). Fifty-four crossbred sows (Yorkshire × Landrace) were allotted to one of four treatments according to a 2×2 factorial arrangement. There was no AF×BFT interaction for any of the measured variables. The body weight change of sows was decreased for <20 mm in BFT... |

ABSTRACT The objective of this study was to evaluate the effects of the addition of the prebiotic fructooligosaccharide and/or alfalfa hay to piglet diets on carcass traits and short-chain fatty acid profiles in the cecal digesta. Seventy-two commercial crossbred piglets of both sexes, with an average initial weight about 6 kg and age of approximately 21 days, were distributed in a randomized block design, using a factorial scheme, which consisted of three alfalfa hay levels (0, 5, and 10%) and two fructooligosaccharide levels (0 and 0.3%). Fiber addition in the presence of the prebiotic exerted an effect on cecal digesta short-chain fatty acid, increasing the acetic and reducing the butyric acid concentrations. The meat quality was also affected by the... |

Commercial cuts yield is an important trait for beef production, which affects the final value of the products, but its direct determination is a challenging procedure to be implemented in practice. The measurement of ribeye area (REA) and backfat thickness (BFT) can be used as indirect measures of meat yield. REA and BFT are important traits studied in beef cattle due to their strong implication in technological (carcass yield) and nutritional characteristics of meat products, like the degree of muscularity and total body fat. Thus, the aim of this work was to study the Longissimus dorsi muscle transcriptome of Nellore cattle, associated with REA and BFT, to find differentially expressed (DE) genes, metabolic pathways, and biological processes that may... |

There is a paucity of information in the literature on body composition changes in Nellore cattle and its crosses, mainly on heifers and intact males. Ultrasound is a useful, low cost tool to easily obtain this information, with minimal animal stress. Effects of sex and days on feed on live weight (LW) and ultrasound Longissimus muscle area (ULMA) and subcutaneous fat thickness (UFAT) measurements were evaluated in F1 Piedmont <FONT FACE=Symbol>´</FONT> Nelore, 27 heifers (HF) and 27 intact males (IM). HF and IM had an initial LW of 256 ± 5.6 and 265 ± 5.6 kg, respectively, and were fed a diet containing 77% TDN for 131 days. LW, ULMA, and UFAT were evaluated at 28-d intervals. Interactions between sex and days on feed were found for all traits... |

The aim of this study was to evaluate performance in feedlot and carcass traits at slaughter of crossbred cattle prior raised grazing tropical grasses and receiving supplement with or without virginiamycin (VM). Steers (n = 34) and heifers (n = 31) produced from matting Nellore, ½ Nellore x ½ Angus and ½ Nellore x ½ Caracu dams with Braford, Charbray and Caracu sires were raised grazing tropical grasses (dividedinto eight paddocks of eight hectares each, formed by Brachiaria brizantha cv. Marandu) and received protein and mineral supplementation with or without VM (included in the supplements to provide an intake of 45 mg 100 kg BW-1) on dry (July to October) and rainy seasons (November to June), respectively, from 9 to 20mo of age |

The selection and evaluation of breeds and purebred lines to be used as the parental stock is an important step for the success of any animal breeding program. In this study, the feed:gain ratio, backfat thickness corrected for 100 kg, age to 100 kg, average daily gain, and age of sow at first farrowing were used to evaluate the genetic trends for direct and maternal additive genetic values in Large White pigs. The total number of piglets born or born alive and the litter weight at birth were used as indicators of the genetic trends for the direct additive values. The genetic trends were calculated by regression of the average predicted genetic values per year for each trait versus the offspring's year of birth (for performance traits) or versus the dam... |

ABSTRACT Aiming at breeding heifers with 14-15 months of age, 100 Hereford calves were subjected to different feeding systems. Heifers grazed on a natural pasture in early winter, fed or not a supplement (14% crude protein; 72% total digestible nutrients), were transferred to a ryegrass pasture for 73 days, and then returned to a natural pasture for 15 days until the beginning of the breeding season. During the last 15 days on ryegrass pasture and the 15 days of the return to the natural pasture, half of the heifers of the two previous systems were offered the supplement, thereby establishing four feeding treatments. Heifers supplemented during the second period, independently of supplementation during the first grazing period, presented higher average... |

Benefits generated by the use of crossbreeding in beef cattle are related to heterosis and complementary effects, not only in the productive aspect, but also in the qualitative aspect of the carcass, mainly in tropical conditions. The aim of this study was to evaluate the effect of sire breed on beef quality of crossbred cattle. Steers (n=89) and heifers (n=104) were produced along two years from mating ½ Nellore + ½ Angus and ½ Nellore + ½ Caracu and Nellore dams with Guzerá, Caracu and Senepol. |

The main objectives of this study were to verify the relationship among body condition at parturition, decrease of backfat thickness and weight during the lactation and the interval from weaning to oestrus of sows. It was performed with 10 gilts and 10 fifth, sixth and seventh parity Camborough sows. The average breeding age and weight of the gilts were respectively 231 days and 149.5 kg. During lactation all females were fed a wet diet (3.34 Mcal/kg, 17% CP), ad libitum. The average daily food consumption was 5.233 for gilts and 5.721 kg for multiparous sows. Ultrasonic measurements of backfat at the P2 site were recorded on day 6 before and days 2, 7, 14, 21 and 25 after parturition. Body weight was recorded on the same dates, except the day before... |

Pesquisas apresentam a existência de variação individual em relação ao comportamento alimentar de bovinos confinados, mesmo estando na mesma baia de confinamento. Objetivou-se avaliar se a seletividade por tamanho de partícula no cocho tem relação com as características de carcaça de bovinos Nelore Mocho. O experimento foi realizado na área de confinamento de junho a novembro de 2012. Foram utilizados 18 animais, com idade e peso médio iniciais de 21 meses e 335 kg, respectivamente, provenientes do rebanho da marca OB. Os animais foram abatidos com idade e o peso médio de 23 meses e 535 kg, e espessura de gordura mínima de 5 mm. Foi mantido um registro diário do ofertado e das sobras recolhidas, por animal. Avaliou-se o tamanho médio de partículas... |

O objetivo deste trabalho foi avaliar o efeito da vitamina E sobre o desempenho, características de carcaça e qualidade do presunto. Noventa e seis suínos foram submetidos aos seguintes tratamentos: controle, 100, 200 e 400 mg de vitamina E por kg de ração, fornecidas a partir de 116 dias antes do abate. Após o abate, as carcaças foram avaliadas, resfriadas, desossadas e o pernil foi removido para fabricação de presunto cozido. Análises dos teores de vitamina E e ácido tiobarbitúrico (TBARS) foram realizadas em amostras de pernil e de presunto. A média do ganho de peso foi 789,81 g por dia, do consumo 2.418 g por dia e da conversão alimentar 3,06. Os animais apresentaram 113,57 kg de peso vivo; 85,90 kg de peso de carcaça; 75,62% de rendimento de carcaça;... |
