Resumo: The ovine production is an activity that has developed gradually in the country, and growing in areas where before the sheep industry was negligible, enabling livestock production systems in small, medium and large farms and becoming a more profitable alternative investment means in agriculture, when compared with other agricultural as for example, beef cattle. objective of this work was to evaluate the effect of inclusion of pearl millet grain replacing corn in the diet of feedlot ovine. SRD 32 lambs were used at 18 + / - 2 kg of body weight. The treatments consisted of four isoenergetic and isonitrogenous diets. The complete rations were fed daily at 8 and 16h and food was weighed individually calculated and remains not to exceed 10% of the total weight of the diet. The design was randomized blocks with four treatments and eight replicates consisting of four levels of millet grain and eight repetitions. The blocks were defined according to weight and age at the beginning of the experiment. There was no significant difference (P <0.05) for average daily weight gain of animals, but we observed a decrease in daily dry matter intake was higher the level of millet in the experimental diets, possibly due to higher content of NDF and ADF contained in these diets.There was no influence of diets (P> 0.05) for NDF, CFDA, and CNDT CPB, but there was a linear increase in intake of NDF and ADF intake which may justify a lower dry matter intake observed in diets with higher concentrations of millet. The fractions (from rapid degradation) and fraction B (potentially degradable) were not affected by replacement of corn by pearl millet grain, as well as the fraction c (hourly rate of degradation of the potentially degradable). Statistical analysis showed no differences (P> 0.05) between the nitrogen fractions as a function of increasing levels of pearl millet. There was no significant difference (P >0.05) for the characteristics of final live weight, hot carcass weight and cold carcass weight of slaughtered animals which can be, for carcass yield and loin eye area was no significant difference between treatment, because of the diets were isonitrogenous and the content of concentrate to be similar in all treatments. Total replacement of corn by pearl millet resulted in 32% reduction in the cost of the diet, totaling R $ 0.14 per kg.Diets T3 and T4 exhibited higher profitability that a diet that contained more corn in the formulation, this is a result of the lower cost of production observed in these diets due to lower price of millet for maize associated with similar performance of pigs fedthus reversing a diet of better pay

Objetivou-se com este trabalho avaliar o efeito da inclusão de milheto grão em substituição ao milho na dieta de ovinos confinados. Foram utilizados 32 cordeiros SRD, com 18 +/- 2 kg de peso corporal. Os tratamentos foram constituídos de quatro dietas isoprotéicas e isoenergéticas. As rações completas foram fornecidas diariamente às 8 e as 16h e os alimentos foram pesados individualmente e as sobras calculadas para não ultrapassar 10% do peso total da dieta. O delineamento foi de blocos casualizados, com quatro tratamentos e oito repetições composto de quatro níveis de milheto grão e oito repetições. Os blocos foram definidos de acordo com o peso e a idade dos animais no início do experimento. Não houve diferença significativa (P<0,05) para o ganho de peso médio diário dos animais, porém foi observada uma redução no consumo de matéria seca diária quanto maior foi o nível de milheto nas dietas experimentais, possivelmente pelo maior teor de FDN e FDA contido nessas dietas. Não houve influência das dietas (P>0,05) sobre o CFDN, CFDA, CPB e CNDT, porém foi observado um aumento linear no consumo de FDN e no consumo de FDA, o que pode justificar um menor consumo de matéria seca observado nas dietas com maiores teores de milheto. As frações a (de rápida degradação) e a fração b (potencialmente degradável) não foram influenciadas pela substituição do milho pelo milheto grão, assim como a fração c (taxa horária de degradação da fração potencialmente degradável). A análise estatística indicou que não houve diferenças (P>0,05) entre as frações nitrogenadas em função do aumento nos níveis de milheto. Não houve diferença significativa (P>0,05) para as características de peso vivo final, peso carcaça quente e peso de carcaça fria dos animais abatidos, para o rendimento carcaça e área de olho de lombo não houve diferença significativa entre os tratamentos, devido ao fato das dietas serem isoprotéicas e do teor de concentrado ser semelhante em todos os tratamentos. A substituição total do milho por milheto resultou em redução de 32% no custo da dieta, totalizando R$ 0,14 por kg de ração. As dietas T3 e T4 apresentaram lucratividade maior que a dieta 1 que continha mais milho na formulação, isso é resultado do menor custo de produção observado nessas dietas em função do menor preço do milheto em relação ao milho associado ao desempenho semelhante dos animais alimentados com a dieta T1 revertendo assim em melhor remuneração.
