| ABSTRACT: The use of lambs from crossing of local with specialized sheep breeds for meat production may lead to higher meat deposition and a smaller fat amount in the carcass, with a more adequate nutritional profile for human consumption. This study investigated the performance, carcass and meat characteristics of lambs from the Morada Nova and Santa Inês locally adapted hair breeds and crosses between Dorper × Morada Nova and Dorper × Santa Inês slaughtered at approximately 35 kg. Morada Nova lambs showed lower (p < 0.05) performance compared to the other genetic groups resulting in a higher age at slaughter (p < 0.05). Crossbred Dorper × Santa Inês and Dorper × Morada Nova lambs showed better characteristics for meat production with better (p <... |

| Objetivou-se neste estudo avaliar o efeito do fornecimento, sem prévia adaptação, durante curto tempo e em diferentes fases do ciclo estral, de dietas contendo nitrogênio não-proteico (NNP) na produção, na qualidade e no grau de desenvolvimento de embriões recuperados em fêmeas bovinas superovuladas. Sessenta e oito vacas Nelore foram distribuídas em três grupos: um controle e dois com fornecimento de ureia antes (UA = do dia -5 ao dia 0) e após (UD = dia 0 ao dia 5) a inseminação artificial. As vacas foram mantidas em pastagem e receberam concentrado (3,0 kg/animal/dia) durante 16 dias. Foram formulados dois concentrados, e as dietas totais (concentrado e consumo estimado de pastagem) apresentaram 12,0% (dieta controle) e 14,6% (dieta NNP) de proteína... |

| Abstract: The objective of this work was to estimate genetic parameters for traits related to resistance to endoparasites in Santa Inês sheep, for a possible inclusion in sheep breeding programs, as well as to evaluate the additive genetic pattern of the animals using cluster analyzes, in order to assess whether there are groups within the population that can be used as candidates for selection for resistance to endoparasites. The studied traits were: Famacha score, fecal egg counts (FEC), packed cell volume (PCV), total plasma protein (TPP), body condition score (BCS), and body weight (BW). Heritability estimates ranged from 0.17 (0.05) for TPP to 0.31 (0.07) for BCS. The cluster analyzes based on the breeding values identified four clusters. Famacha and... |

| The objective of this work was to evaluate the reproductive performance of Santa Inês ewes fed a diet supplemented with protected fat. Intervals from lambing to first clinical estrus and to conception, conception rate, prolificacy, live weight and body condition were determined. After lambing, 60 ewes and their offsprings were weighted and randomly assigned to three treatments, based on age, body weight and number of born lambs. Treatments consisted of: control diet, or control diet plus 30 g of protected fat, from lambing to day 25 of post-lambing (Sup25), or to day 60 of post-lambing (Sup60). Out of 60 evaluated ewes, 93.3% returned to estrus, and 74.5% got pregnant, with 73.53% lambing rate and 196.5 days lambing interval. The average periods from... |
