Summary: | The objective of this work was to evaluate the effect of using multiple supplements with different levels of cottonseed meal 38% on intake, total apparent digestibility of dietary components, efficiency of microbial synthesis and productive performance of beef heifers in Brachiaria decumbens pasture during the rainy season. It was used 25 Nellore heifers and 10 crossbred heifers with predominance of Zebu breed at 16 months of age and with 249.8 ± 0.6 kg of body weight. It was used a complete random experimental design with five treatments and seven replicates. Supplements contained approximately 30% of crude protein (CP) and soybean meal replaced by cottonseed meal 38% at the levels 0; 33; 67 and 100%, (CS0, CS33, CS67 and CS100, respectively) evaluated in relation to a control group, which received only mineral mixture (MM) ad libitum. Daily weight gain was 397, 546, 570, 525 and 542 g, respectively, for the groups MM, CS0, CS33, CS67 and CS100. There was no effect of the levels of cottonseed meal 38% on daily weight gain, which differed among animals fed supplement and control group, however. Intakes of crude protein and non-fibrous carbohydrates (NFC) in kg/day were greater in groups under supplementation. Coefficients of total apparent digestibility of CP and NFC were greater in animals fed supplements in relation to the control group. Increase on the replacement level of soybean meal by cottonseed meal had a positive linear effect on coefficients of total apparent digestibility of DM, organic matter and CP. There was no difference on microbial efficiency, expressed as g of crude protein per kg of TDN consumed by the animals under supplements and the ones of the control group, neither it was observed difference among levels of replacement of soybean meal by cottonseed meal. The use of cottonseed meal 38% replacing soybean meal in the diet does not harm performance of grazing beef heifers. |
