| RESUMO - A suplementação mineral faz-se necessária uma vez que a forragem não supre a exigência dos animais. O consumo diário do suplemento visa o atendimento do déficit necessário para o ganho de peso, podendo ser modificado pela palatabilidade mediante o teor de sódio da mistura e/ou a inclusão de aromatizantes. Objetivou-se avaliar dois níveis de concentração de aromatizante no suplemento mineral sobre o consumo do suplemento, comportamento de cocho e desempenho em bovinos de corte. Utilizou-se 80 garrotes Nelore (11 ± 2,5 meses), divididos em quatro lotes de 20 animais cada, alocados em pasto de Brachiaria brizantha cv. Marandu. Os tratamentos foram constituídos de suplementação mineral para recria (65 P), com aromatizante na concentração de 750... |

| Nitrogen (N) at 100, 200, 300, and 400 kg ha-1 was applied to Tanzania grass swards to evaluate the animal response and relationships between sward characteristics and the performance of young Nellore bulls (Bos indicus) under continuous stocking. A completely randomized experimental design was used with two replications between 11 November 2001 and 15 April 2002 when the sward heights were maintained at 60 cm by using different stocking rates. The average daily gain (ADG) (0.73 kg d-1) was not affected by N doses while the number of animal days ha-1 increased linearly from 515 to 1267. On the other hand, the linear increase in the animal yield was 399, 653, 755, and 895 kg ha-1 for N at 100, 200, 300, and 400 kg ha-1, respectively, while the ratio between... |

| Para que o produtor se adapte aos novos moldes de produção, um intenso controle sobre os dados do rebanho deve ser empregado nos sistemas de produção de leite. Além de produzir com eficiência, sustentabilidade ambiental, responsabilidade social e sem desperdícios é preciso desenvolver habilidades no gerenciamento e motivação de pessoas para comprar insumos, na venda da produção e na gestão adequada dos custos. Desta forma, há necessidade que o produtor desenvolva ferramentas e práticas de monitoramento de seus dados para processar, interpretar e transformá–los em informação. Vários fatores afetam o registro e gestão dos dados da fazenda. O efetivo uso de registros representa um “divisor de águas” na medicina moderna do gado de leite. A coleta de dados... |

| The objective of this study was to assess the bionutritional efficiency of crossbred F1 Red Angus × Nellore (½ RA ½ N) and F1 Blonde D'Aquitaine × Nellore (½ BA ½ N) young bulls finished on feedlot and slaughtered at 480, 520 and 560 kg body weight. A completely randomized experimental design in a 2 × 3 (genetic group × slaughter weight) factorial arrangement with six replicates was used. The ½ BA ½ N young bulls showed higher kidney, pelvic and inguinal fat (KPIF, kg and % BW) and lower multivariate biological nutritional index (MBNI) and residual feed intake than ½ RA ½ N young bulls. The young bulls slaughtered at heavier weight had larger ribeye area (cm²), fat thickness over the 12-13th rib, fat thickness over the rump, KPIF (kg and % BW), dry matter... |

| O híbrido BRS RB331 Ipyporã é resultado de um cruzamento entre B. ruziziensis e B. brizantha realizado em 1992, na Embrapa Gado de Corte e liberado pela Embrapa em 2017 em parceria com a UNIPASTO, após 13 anos intermitentes de avaliações. É uma planta de porte baixo, prostrado, com colmos delgados de bainhas muito pilosas e folhas pilosas em ambas as faces. As espiguetas são uniseriadas e com pouca ou nenhuma pilosidade. A BRS Ipyporã entra no mercado para suprir a demanda por uma cultivar de Brachiaria de boa produtividade e manejo relativamente fácil, como a cv. Marandu, porém com elevado grau de resistência à cigarrinha da cana do gênero Mahanarva, além de apresentar resistência às cigarrinhas típicas de pastagem dos gêneros Deois e Notozulia,... |

| ABSTRACT: This research aimed to assess Girolando calves’ concentrate intake and performance when placed in shelters with distinct roofing materials and programs of supplementary lighting during the milk-feeding stage. In order to so, we used a completely randomized design with a 3×3 factorial arrangement, with three replications. Females Girolando calves (n=27) were assigned in individual shelters at random with 3 different roofing materials (fiber cement tile, recycled tile and thatched roofs) and subjected to three lighting programs (12, 16 and 20 hours). No interaction was observed between roofing material and lighting programs, whilst no significant effect (P>0.05) was observed among the roofing materials. The supplementary lighting, by providing... |

| ABSTRACT Environmental temperatures currently considered within comfort zone for broiler rearing may be misleading or even obsolete from actual values. Some factors such as animal genetics, nutrition and poultry management, mainly acclimatization to tropical and subtropical conditions, influence in determining the comfort zone for birds. This study aimed to evaluate the effects of five different thermal environments on animal welfare and rearing performance of broiler chickens, setting an ideal temperature range (comfort zone) for each of the first three weeks of poultry breeding. The chicks (375) were randomly placed into five climatic chambers set to distinct thermal conditions, being: one as recommended by the literature, another as stated by Cassuce... |

| ABSTRACT The objective of this study was to evaluate the influence of a synthetic progesterone ear implant on the behavior, physiological responses, and number of carcass injuries of Nellore females. Twenty-eight Nellore heifers with an average initial weight of 240.89 kg were used in the experiment. All animals received the same dietary management, in an intensive rearing system with mineral salt and water ad libitum. Heifers were distributed in a completely randomized design with two treatments (with and without progesterone ear implant) and seven replications, in 14 stalls. Analyses of variance and correlation were performed. In the evaluation of the feeding, rumination, rest, sleeping, social, and body-care behaviors, no significant differences were... |

| This trial was conducted aiming to evaluate the effects of Brachiaria brizantha vegetative seed harvest residues hay treated with anhydrous ammonia (NH3) or urea, and protein sources on the steers performance, and carcass quality. Twenty-four male beef cattle were (12 F1 Nellore X Aberdeen Angus and 12 F1 Nellore X Red Angus), distributed in four treatments, with six replications. Animal crossbreed type and initial body weight were considered blocks. The diets were: Untreated hay supplemented with non-protein nitrogen (UHNPN); untreated hay supplemented with cottonseed meal (UHCM), hay treated with 5% urea (HTU), hay treated with 3% anhydrous ammonia (HTA) of DM%. Diets were formulated to be isoproteic and isoenergetic. The initial body weight (kg), daily... |

| The objective of this study was to evaluate the postweaning history of heifers kept on marandu grass pastures with three canopy heights, in a continuous-grazing system, during the rainy period, on feedlot- or pasture finishing. The effects of three canopy heights (15, 25 and 35 cm) associated with two supplements (mineral salt and protein-energy supplement) and two finishing systems in the dry period (feedlot and open pasture) were studied in the postweaning period during the rainy season. The adopted design was completely randomized, with seven replications (animals) in a 2 × 2 factorial arrangement. The animals which received protein-energy supplement reached the finishing period with greater body weight in relation to those fed mineral salt. In both... |

| The objective of this study was to verify the effect of low-intake supplementation on performance of Nellore young bulls kept on Marandu grass pasture. The experiment was divided in two periods: the dry and rainy seasons. Treatments during the dry period were composed of mineral salt with urea and mineral supplement enriched with true protein and additive. In the rainy period treatments were mineral salt and enriched mineral supplement only. Pastures were evaluated and animals were weighed in both evaluation phases. The variables studied were evaluated in a completely randomized design in a split-plot arrangement, where plots were treatments and subplots were the periods within each phase, considering the types of supplementation as treatments. During the... |
