Resumo: | This study aimed to evaluate the correlations of intake, digestibility and performance with the ingestive behavior of lambs fed diets containing ammoniated buffel grass hay. Buffel grass hay was treated with four levels of urea (0, 18, 36 and 54 g/kg DM basis) and eight repetitions. Thirty-two sheep with no defined breed and an average body weight of 17.7 ± 1.8 kg were distributed in a completely randomized design. It was observed positive correlations were found between the feeding time and the intake of dry matter (r = 0.3120), organic matter (r = 0.3242), neutral detergent fiber (r = 0.3800), total carbohydrates (r = 0.3343) and total digestible nutrients (r = 0.3233). Positive correlations (P < 0.05) were found among the rumination efficiencies, g of DM/h and g of NDF/h with nutrient intake variables, except for ether extract intake. Positive correlations were observed (P < 0.05) between both total weight gain (TWG) and average daily gain (ADG) and the rumination efficiency, g of DM/h (r = 0.3330) and g of NDF/h (r = 0.3304). The feeding and rumination efficiencies have a positive relationship with the total digestible nutrients. The correlation among intake, digestibility and performance variables with the ingestive behavior, it was important for the understanding of diet containing ammoniated buffel grass hay, in which the positive correlation of rumination efficiency with intake and weight gain explained the favorable effect on productive performance of feedlot sheep. |

Objetivou-se avaliar as correlações entre o consumo, digestibilidade e desempenho com o comportamento ingestivo de cordeiros confinados alimentados com dietas contendo feno de capim-buffel amonizado. Os tratamentos experimentais consistiram em quatro dietas contendo os fenos de capim-buffel amonizados com as diferentes concentrações de uréia (0, 18, 36 e 54 g/kg na MS) e oito repetições. Foram utilizados 32 ovinos sem padrão racial definido (SPRD), com peso vivo médio de 17,7 ± 1,8 kg, distribuídos em delineamento experimental inteiramente casualizado (DIC). Foram verificadas correlações positivas entre o tempo de alimentação e os consumos: de matéria seca (r=0,3120), matéria orgânica (0,3242), fibra em detergente neutro (r=0,3800), carboidratos totais (r=0,3343) e nutrientes digestíveis totais (r=0,3233). Correlações positivas (P < 0,05) foram encontradas entre as eficiências de ruminação, g MS/h e g FDN/h, com as variáveis de consumo de nutrientes, exceto para consumo de extrato etéreo. Indicando conformidade dos resultados com as variáveis de consumo, foram observadas correlações positivas (P < 0,05) encontradas para ganho de peso total e ganho médio diário entre as eficiências de ruminação, g MS/h (r=0,3330) e g FDN/h (r=0,3304). As eficiências de alimentação e ruminação apresentam relação positiva com os nutrientes digestíveis totais. O estudo da correlação entre as variáveis foi importante para o entendimento da dieta contendo feno de capim-buffel amonizado, onde a correlação positiva da eficiência de ruminação com consumo e ganho de peso explicaram o efeito favorável no desempenho produtivo de ovinos confinados.UEL2016-06-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2157210.5433/1679-0359.2016v37n3p1551Semina: Ciências Agrárias; Vol. 37 No. 3 (2016); 1551-1564Semina: Ciências Agrárias; v. 37 n. 3 (2016); 1551-15641679-03591676-546Xreponame:Semina.
