The purpose of the experiment was to study the feeding value of micro storage and ammoniated corn stalks on Liaoning Cashmere goats. A total of 24 Liaoning Cashmere goats with an average weight of (24.14±1.02) kg were selected and randomly divided into three groups, with eight replicates in each group and one sheep in each replicate. Group I was control group, the roughage was corn stalks+peanut stalks+alfalfa hay, group II was micro storage corn stalks+peanut stalks+alfalfa hay, and group III was ammoniated corn stalks+peanut stalks+alfalfa hay. The formal trial period was 30 d, during which the metabolic test was conducted for 7 d. The results showed that the CP content of corn straw after micro storage and ammoniation treatment increased by 14.84% and 93.70% respectively, and the CP content of ammoniated straw was significantly higher than that of the other groups (P<0.05). The average daily gain of test sheep in group II and group III was significantly higher than that in control group (P<0.05), and the feed to gain ratio was significantly lower than that in control group (P<0.05). The apparent digestibility of CF, NDF and ADF in control group was significantly lower than that in test group (P<0.05). The study indicates that the micro storage and ammoniation can increase the content of CP, reduce the content of corn straw fiber, improve its quality, increase the digestibility of nutrients, improve the growth performance, and increase economic benefits. The micro storage treatment of corn straw has the best effect. [ABSTRACT FROM AUTHOR] |
