摘要
本试验通过对生产的不同精粗比例TMR颗粒饲料外观、色泽、光滑度、味道、质地的观察分析;对其含粉率、粉化率、硬度、容重、密度、长度的测定分析;并进行饲养试验,测定肉羊采食量、日增重、计算其料重比,然后进行经济效益分析,最终确定最佳精粗比,玉米秸秆和苜蓿干草最佳配比TMR颗粒饲料。结果表明:在精粗比50:50,玉米秸秆与苜蓿干草比l:2时,颗粒饲料感官性状最好,物理性状最佳,肉羊平均日增重最高,料重比最低,净收入最高。
Through the observation and analysis of the appearance,color,smoothness,taste and texture of tpellet with different ratio of concentrate to coarse,the flour content,pulverization rate,hardness,bulk density,density and length of tpellet were measured and analyzed.The feed intake,daily gain,feed-to-weight ratio of mutton sheep were measured,and the economic benefit was analyzed.Finally,the best concentrate-to-roughage ratio,the best ratio of corn stalk and alfalfa Hay were determined.The results showed that the sensory and physical properties of pellet feed were the best when the ratio of concentrate to forage was 50:50 and the ratio of corn stalk to alfalfa hay was 1:2.The average daily gain of mutton sheep was highest,the ratio of forage to gain was lowest,net income was highest.
