Effects of different proportions of forage triticale silage on the fattening effect of Pingliang red bull
In order to explore the effects of different supplemental proportions of forage triticale silage on the finishing effect of Pingliang red bull.Twenty Pingliang red bull with the same breed,month age and weight were selected and randomly divided into 5 groups,with 4 heads in each group.Beef in the control group were fed a basic diet,and those in the experimental groups were fed the basic diet supplemented with 30%,50%,70% and 100% Gannong 2 forage triticale silage instead of corn silage,respectively.The pre-experiment and formal experiment were respectively conducted 10 days and 90 days.The results showed that 30 days before fattening,the average daily gain of the test group was significantly lower than that of the control group by 23.48%,13.64%,21.21% and 27.27%(P<0.05),and the average daily feed intake was significantly lower than that of the control group by 4.10%,6.30%,5.87% and 10.28%(P<0.05),and the feed weight ratio was significantly higher than that of the control group(P<0.05).After 30~90 days of fattening,the average daily gain of the test group was significantly reduced by 6.11%,16.79%,29.01% and 16.03% compared with the control group(P<0.05).Compared with the control group,the average daily feed intake decreased by 4.63%,15.09%,4.86% and 21.14%respectively(P<0.05).Compared with the first 30 days,the average daily gain and average daily feed intake of group A increased by 21.78% and 6.44% respectively,and the feed weight ratio decreased by 3.19%.During the whole fattening period,the average daily food intake and the average daily weight gain in experiment groups were significantly lower than that in the control group(P<0.05).Group A had the lowest feed weight ratio and the highest net income.Considering the production performance and economic benefits,when 30% Gannong 2 triticale silage replaced the whole plant corn silage in the diet roughage,although the daily weight gain was reduced,the daily feed intake,feed weight ratio and breeding cost of the test cattle were the lowest,and the economic benefits were the highest.
