Resumo: | The objective with this work was evaluate the effect of level different of low intake supplements on body weight (BW) change, body condition score (BCS), intake, digestibility and protein microbial efficiency of non-pregnancy cow, crossbreed, with Nellore blood predominance and initial BW of 394.7±13.14 kg in Urochloa decumbens Stapf during dry season. Four treatments were evaluated: Control (without supplementation), T250, T500, and T750, corresponding 250, 500, and 750 g of supplement/animal/ day, respectively. The experiment was carried in a completely randomized experimental design. There was not effect of the level supplementation on final BW, average gain daily (AGD), and BCS, with average of 409.8 kg, 0.181 kg, and 4.85 point, respectively. There was increase (P<0.10) of the intake of crude protein (CP), non-fibrous carbohydrates, and ether extract (EE) with the level supplementation. The average total dry matter intake was 20.31 g/kg of BW. The digestibility coefficients dry matter, organic matter, neutral detergent fiber, and total digestible nutrients showed a quadratic response and a linear effect (P<0.10) on digestibility coefficients of the CP and EE according supplementation level. The supplementation level not influenced (P>0.10) the microbial protein synthesis. Concluded that level supplementation increased the nutrient amount, but not able to increase the performance the animals. |

Quatro tratamentos foram avaliados: Controle (somente mistura mineral), T250, T500 e T750, sendo 250, 500 e 750 g de suplemento/animal/dia, respectivamente. O experimento foi estruturado em delineamento inteiramente casualizado. Não houve efeito dos níveis de fornecimento de suplemento sobre o peso corporal final (PCF), ganho médio diário (GMD) e ECC final (ECCF), com médias de 409,8 kg, 0,181 kg e 4,85 pontos, respectivamente. Quanto ao consumo de nutrientes da dieta, observou-se que o consumo de proteína bruta (PB), carboidrato não-fibroso e extrato etéreo (EE) em kg/dia aumentaram à medida que aumentou-se os níveis de suplementação. O consumo de matéria seca (MS) médio foi 20,31 g/kg de peso corporal. Notou-se efeito quadrático (da suplementação sobre os coeficientes de digestibilidade da MS, matéria orgânica, fibra em detergente neutro corrigida para cinza e proteína e nutrientes digestíveis totais. Efeito linear foi observado para os coeficientes de digestibilidade da PB e EE. O fornecimento de diferentes níveis de suplemento não influenciou a eficiência de síntese de proteína microbiana. Conclui-se que a suplementação em baixos níveis promove maior aporte de nutrientes, mas não é efetiva em promover mudanças no peso corporal de vacas não-gestantes.UEL2014-08-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1348910.5433/1679-0359.2014v35n4p1999Semina: Ciências Agrárias; Vol. 35 No. 4 (2014); 1999-2010Semina: Ciências Agrárias; v. 35 n. 4 (2014); 1999-20101679-03591676-546Xreponame:Semina.
