Resumo: | The objective of the study was to evaluate the effect of different proportions of high-level diets on finishing lambs in feedlot system on performance. However, there is no ingestive and physiological behavior, as well as carcass characteristics, quality physical and chemical characteristics of meat and production costs. For this purpose, whole corn grain associated with the protein-mineral-vitamin supplement was used in three proportions of concentrate: bulky (100%, 80:20 and 60:40%), a concentrated portion of the diet composed of 85 % of whole corn grain and 15% of supplement and bulky portion of Tifton hay). Twentyfour non-castrated males with no defined racial pattern were used with initial weight of 20.9 ± 1.0 kg at the age of 6 months. Weight gain was achieved in the three diets tested from 0.302g / day for 100% diet, 0.254g / day to 80:20 and 0.259g / day for 60:40 Minor rumination time (P≤0.05) in lambs of the treatment based on grain 100% when compared to the lambs of the other treatments. The 100% diet presented higher feed efficiency (EAL) and also more efficient rumination (ERU). Evaluating a temperature of the rumen region, it can be seen that the animals that received a 100% diet showed the variation of the temperature of the reen region, as 80:20 and 60: 40% diets affect nearby temperatures. As evaluated diets contributed to the performance with satisfactory gains, although preferences of use of diet of high grade, these guarantee like basic actions. There was a significant effect on carcass yield. A 100% concentrated diet showed a carcass yield of 47%, while for 80: 20% and 60: 40% diets obtained carcass yield values of 43.5% and 43.4%, respectively. The gastrointestinal content also had an effect, being lower in treatments 100% and 80: 20%. (P> 0.05) in the variables pH, temperature, color, water retention capacity and shear force. The 100% treatment presented a weight loss in cooking as well as superior thiobarbituric acid (TBARS) when compared with other diets. The 100% diet, when compared with other diets, obtained an additional carcass weight of 2.30 kg per animal. The use of the 100% concentrated diet in lamb termination systems is a more viable alternative from a productive and economical point of view |

Utilizou-se para tal, grão de milho inteiro associando ao suplemento protéico-mineral-vitamínico em três proporções de concentrado:volumoso, (100%, 80:20% e 60:40%), sendo a porção concentrada da dieta composta de 85% de grão de milho inteiro e 15% de suplemento e a porção volumosa de feno de Tifton). Foram utilizados 24 machos não castrados, sem padrão racial definido com peso inicial de 20,9 ± 1,0kg com idade de 6 meses. Conseguiu-se obter ganhos de peso nas três dietas testadas de 0,302g/dia para dieta 100%, 0,254 g/dia para 80:20 e 0,259 g/dia para 60:40 O tempo de ruminação foi menor (P≤0,05) nos cordeiros do tratamento à base de grão 100% quando comparados aos cordeiros dos demais tratamentos. A dieta 100% apresentou maior eficiência de alimentação (EAL) e também mais eficiente na ruminação (ERU). Avaliando a temperatura da região do rúmen percebe-se que os animais que receberam a dieta 100% apresentaram acentuada variação de temperatura da região do rémen, as dietas 80:20 e 60:40% apresentam alterações de temperaturas próximas. As dietas avaliadas contribuíram para o desempenho com ganhos satisfatórios, apesar de ocorrer alterações comportamentais com uso da dieta de alto grão, estas garantem as ações básicas necessária para manter a saúde ruminal adequada. Houve efeito significativo para rendimento de carcaça. A dieta 100% concentrado apresentou um rendimento de carcaça de 47%, enquanto as dietas 80:20% e 60:40% obtiveram valores para rendimento de carcaça de 43,5% e 43,4% respectivamente. O conteúdo gastrointestinal também apresentou efeito, sendo menor nos tratamentos 100% e 80:20%. Para os parâmetros físicos da carne, não foi observado diferenças significativa (P>0,05) nas variáveis pH, temperatura, cor, capacidade de retenção de água e força de cisalhamento. O tratamento 100% apresentou uma menor perda de peso na cocção assim como também apresentou ácido tiobarbitúrico (TBARS) superior quando comparado as demais dietas. A dieta 100%, quando comparado as demais dietas, obteve-se um peso adicional de carcaça de 2,30 Kg por animal. O uso da dieta 100% concentrado em sistemas de terminação de cordeiros é a alternativa mais viável do ponto de vista produtivo e econômicoCoordenação de Aperfeiçoamento de Pessoal de Nível SuperiorUniversidade Federal Rural do Semi-ÁridoBrasilUFERSAPrograma de Pós-Graduação em Ciência AnimalLima, Patrícia de Oliveira76517780491http://lattes.cnpq.br/549109503959862105004280428http://lattes.cnpq.br/8263319263884054Barreto, Hilton Felipe Marinho02824399430http://lattes.cnpq.br/5954383462758700Assis, Liz Carolina da Silva Lagos Cortes02544837470http://lattes.cnpq.br/7511383482412937Ricarte, Aracely Rafaelle Fernandes01059156458http://lattes.cnpq.br/4007401711771523Gonçalves, Josemir de Souza89882814387http://lattes.cnpq.br/4311361775779647Leite, Helia Maria de Souza2018-02-20T14:31:17Z2017-09-25info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfapplication/pdfLEITE, Helia Maria de Souza.
