不同精粗料组合对冬季舍饲羯滩羊的肥育效果
EFFECTS OF DIFFERENT DIET COMPOSITIONS ON THE FATTENING OF THE PEN FEEDING TAN—SHEEP DURING THE WINTER
【摘要】 本文以胡麻饼替代农户传统补饲用的碗豆,同时搭配丰裕的玉米秸,并对小麦秸进行氨化处理,寻求符合当地条件,饲喂效果较好的冬季舍饲滩羊的日粮组合。结果表明含15%胡麻饼的 A2配方+玉米秸(B1)日粮组合的采食量及日增重极显著高于 A1(碗豆)配方+玉米秸(B1)的日粮组合(P<0.01);屠宰率及纯收入亦较高。麦秸氨化后与 A2配方组台,饲喂效果和经济效益接近最好的 A2+B1日粮组合。
【Abstract】 Sixteen wethers were randomly selected and 2×2 Latin Square trial design was used in this study which aimed at choosing an optimized diet composition for the stall-fed Tan-sheep in winter.The volun- tary feed intake and the daily weight gain for A2×B1 ration(concentrate containing 15% flax meal plus corn stalk)were considerably higher than those of other three diet compositions(P<0.01);meanwhile, the slaughter rate and the economic benefit of A2×B1 ration were also better than those of other ra- tions.When the stall-feeding wethers were fed with the ammoniaed wheat straw plus A2 concentrate,same results to the A2×B1 ration were obtained.
