| A redução da idade de abate e a utilização de cruzamentos tem sido fundamental na intensificação do sistema de produção de bovinos de corte (5). O cruzamento entre animais de raças europeias adaptadas e não adaptadas com raças zebuínas, permite o aproveitamento da complementaridade entre raças e da heterose, tanto materna quanto individual, incrementando assim, o desempenho dos animais nas fases pré e pós desmama (1) e favorecendo a melhoria da qualidade da carne obtida (4). Sendo assim, o objetivo deste estudo foi avaliar a influência dos grupos genéticos maternos e paternos e o desempenho de diferentes grupos genéticos quanto às variáveis de peso ao nascimento (PN), peso a desmama (P240) e peso ao sobreano (P550). |

| Crossbreeding represents an important technique to improve growth, beef quality and adaptability in beef production systems in tropical countries. The aim of this study was to evaluate sire and dam breed effects on performance and carcass traits of crossbred cattle produced in a tropical environment. Heifers and steers were evaluated during the pre-weaning, the post-weaning (n = 173) and the finishing phase (n = 123). Animals were produced by mating Nellore (N_N), Angus × Nellore (A_N) and Caracu × Nellore (C_N) dams with Braford, Charbray and Caracu sires. After weaning, animals were raised grazing on Marandu grass for 12 months; thereafter they were housed in individual pens and finished in a feedlot, receiving a total mixed ration. Ultrasound carcass... |

| The aim of this study was to evaluate the effect of sire breed on performance and feed efficiency in feedlot of crossbred cattle. Steers (n=74) and heifers (n=71) produced along two years by breeding Nellore, ½ Nellore x ½ Angus and ½ Nellore x ½ Caracu cows with Braford (BF), Charbray (CC) and Caracu (CR) sires were raised grazing tropical grasses until 20 months (mo) of age and then finished in feedlot for 4 mo. Animals were kept in individual pens allowing measuring of daily dry matter intake (DMI) during finishing phase in feedlot. Weight records were taken in the beginning (BBW) and in the end (EBW) of the feedlot as well as every 28 days to calculate average daily gain (ADG). Feed conversion rate (FCR) was used as a measure of feed efficiency. Data... |

| 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 |

| he aim of this study was to assess performance and carcass traits of crossbred cattle raised grazing tropical grasses, receiving supplement with or without virginiamycin (VM). Steers (n = 49) and heifers (n = 56) 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 ( Brachiaria brizantha cv. Marandu) from 9 to 20 mo of age. The animals were divided into eight paddocks of eight hectares each, with care to form groups containing individuals of all genetic groups and balanced in age and average body weight (BW). During the dry season (July to October) cattle received protein supplements containing (n = 52) or not VM (n = 53), formulated for intake of 1 g... |

| The aim of this study was to assess performance of crossbred steers surgically castrated or immunocastrated. Steers produced along two years from mating Nellore, ½ Nellore x½ Angus and ½ Nellore x ½ Caracu dams with Braford, Charbray and Caracu sires were raised grazing tropical grasses until 20 months of age (n = 80; 40 per treatment) and finished feedlot for 4 months (n = 64; 32 per treatment). The selection of animals that were finished feedlot was performed in order to remove those with more discrepant weights in relation to the mean at the end of backgrounding period, keeping balanced the number of individuals of each evaluated genetic group. Animals were kept in individual pens allowing measuring of daily dry matter intake (DMI) and weight records... |

| O objetivo deste trabalho foi avaliar o efeito de dietas suplementadas com monensina ou produtos à base de própolis, nas populações de protozoários ciliados no rúmen de bovinos (Bos taurus) e bubalinos (Bubalus bubalis). Quatro bovinos da raça Holandesa e quatro búfalos da raça Murrah adultos, fistulados no rúmen, foram distribuídos em delineamento quadrado latino (4x4). A dieta constituiu-se de 50% de silagem de milho e 50% de concentrado à base de milho em grãos e farelo de soja, com adição de monensina sódica ou aditivo à base de própolis LLOSA2 ou LLOSC1. As amostras do conteúdo ruminal foram coletadas duas horas após a alimentação. O gênero Entodinium foi o mais representativo em todos os tratamentos, para ambas as raças de ruminantes. Em búfalos, foi... |
