The aim of this study was to evaluate the effect on intake, apparent digestibility, and ruminal constituents of sheep in response to the addition of increasing levels of babassu mesocarp flour (BMF) to the diet. Twenty crossbred sheep (29.17 ± 2.23 kg) were used in a randomized complete block design. Lambs were confined for 21 days, with 16 days for diet adaptation and 5 days for data collection, in which they were fed an isonitrogenous diet (16.5 ± 0.2 CP, DM basis) containing 70% of concentrate and 30% (DM basis) of Tifton 85 hay. Increasing levels of BMF were 0, 10, 20, and 30% (DM basis). There was a quadratic effect ( < 0.05) on the DM intake, nutrients intake, and digestibility of CP and NFC. The digestibility of DM, OM, TC, and NDF decreased linearly, while EE digestibility increased linearly with increasing levels of BMF. The high NDF content presented in the chemical composition of the babassu mesocarp flour ranked the same as fibrous food, which can limit the inclusion in the diet of high production animals. So, babassu mesocarp flour is an alternative for energy source in lambs feed and can be added at levels up to 10%.
本研究的目的是评估在日粮中添加不同水平的巴巴苏中果皮粉(BMF)对绵羊采食量、表观消化率和瘤胃成分的影响。采用随机完全区组设计,选用20只杂交绵羊(体重29.17±2.23千克)。羔羊被圈养21天,其中16天用于日粮适应,5天用于数据收集,期间给它们饲喂一种等氮日粮(干物质基础上粗蛋白含量为16.5±0.2%),该日粮含有70%的精料和30%(干物质基础)的蒂夫顿85干草。BMF的添加水平分别为0、10、20和30%(干物质基础)。干物质采食量、养分采食量以及粗蛋白和非纤维性碳水化合物的消化率存在二次效应(P<0.05)。随着BMF添加水平的增加,干物质、有机物、总碳水化合物和中性洗涤纤维的消化率呈线性下降,而粗脂肪消化率呈线性增加。巴巴苏中果皮粉化学成分中高含量的中性洗涤纤维与纤维类饲料相当,这可能会限制其在高产动物日粮中的添加量。因此,巴巴苏中果皮粉可作为羔羊饲料中的能量来源替代品,添加水平可达10%。
