湿喂法在断奶仔猪生产中的应用

断奶仔猪采用湿喂法能提高仔猪的生产性能 ,改善其健康状况。一方面 ,液体日粮容易被仔猪接受 ,这样可以防止仔猪断奶后采食量的急速下降。另一方面 ,加水后成液态的饲料在自然条件下会发酵 ,这导致饲料中的乳酸菌数量增加、乳酸浓度上升、pH值下降。与喂干粉饲料相比 ,给断奶后仔猪喂液体日粮能够改善仔猪消化道的内环境 ,减少疾病 ,提高干物质采食量和日增重。

Liquid Feeding in the Weaned Piglet Prodlution

Liquid feeding can improve the performance and health of post weanling piglets.On the one hand,liquid diets are more likely to be accepted by piglets,which may prevent the sharp decling of food intake after early weanling.On the other hand,after fermented,wet feed is characterized by a high number of lactic acid bacteria,a high concentration of lactic acid and a low pH,Consequently,the milieu of digestive tract including GI structure,GI acidity,microbial activities and digestive enzyme activities can be affected by supplying piglets with wet diets.Compared with feeding dry feed,feeding liquid diets may increase DM intake and daily weight gain of young pigs.
