摘  要:
在18头15~30 kg阶段生长育肥猪饲料中分别添加15%2、5%微贮玉米秸秆,研究微贮玉米秸秆对猪育肥效果及养分利用的影响.试验结果表明,在饲粮中分别添加15%和25%的微贮玉米秸秆,猪采食率下降了11.3%和18.9%;日增重下降了31.4%和42.4%;饲料转化率也随微贮玉米秸秆添加量增大而下降;同时饲粮添加微贮玉米秸秆还会影响生长猪对Ca、P的利用.据此认为在猪饲料中添加微贮玉米秸秆降低了猪的生长性能,不利于饲粮养分的利用.

摘  要:
Eighteen swines at 15 to 30 kg of weight were introduced to study the effect of microorganism fermentation of maize stalk on the growth performance and the nutrient utilization of finishing swine.The results indicated that added microorganism fermented maize stalk in the diet at 15 % and 25 % decreased the growth performance of the finishing swine,reduced the diet nutrient utilization.It is suggested that microorganism fermented maize stalk in the diet should be lower than 15%.
