采光保温猪舍养猪效果的评价

EVALUATION ON EFFECT OF FEEDING FATTENING PIGS IN LIGHTING AND WARMING PIGSTY

在寒冷季节(12—4月份)进行试验,比较采光保温猪舍内外饲养条件下肥育猪的生长情况。结果表明:在采光保温猪舍内养猪具有耗料少、增重快的优点,在132天的试验期内,试验组比舍外环境中饲养的对照组平均多增重3.1kg(P>0.05),少耗料26.82kg,试验组的料肉比显著低于对照组(P<0.01)。并测得采光保温猪舍有较好的采暖和保温性能,舍内的温度(Y)随外环境温度(X)变化而改变的幅度较小,两者符合方程式Y=7.7135+0.2926X(r=0.8412;n=5;P<0.05),即舍内温度平均比舍外环境中高7.7℃。

The trial was Carried out during the cold months(December to next April) to determine the performances of fattening pigs in lighting and warming pigsty. The results showed that pigs raised in lighting and warming pigsty ate less and grew faster than those in exposure;body weight gain of pigs in warming pigsty was 3.1kg more than that of pigs in exposure pigsty and the accemulated food consumption was less 26.82kg in 132 days. The food conversion ratio in experimental group(4.47)was significant lower than that in control group(5.51). Changes of temperatures in The warming pigsty and in exposure were also determined. The warming pigsty had good heat preservation, the temperature of inside pigsty was less effected by the change of outside temperature two temperatures has linear corrlation,the regression equation was Y=7.7135+0.2926X,r=0.8412,n=5, P>0.05. This means that the average temperature in lighting and warming pigsty was 7.7135鈩?higher than that in exposure.
