Is ordinary soybean meal or puffed soybean meal better for pig feed?

Expanded soybean meal for piglets is good, easy to digest and has high utilization rate. Zhongda pig's joke system is developed, ordinary soybean meal can be used, and puffed material is of course better. Generally speaking, it is better to expand.

Application of expanded soybean meal in pig feed. Adding a certain amount of expanded soybean meal to the diet can promote the feed intake, daily gain and reduce the feed-meat ratio of pigs, and at the same time reduce the diarrhea rate of suckling pigs. In addition, expanded soybean meal can also be used as a substitute for fish meal in piglet feed. Sun Peixin et al. (2006) studied the effect of expanded soybean meal on the growth performance of piglets, and concluded that expanded soybean meal could increase the feed intake of piglets (P < 0.05), increase the daily gain by 5.65438 0% and reduce the diarrhea index by 365438 0.6%.

Effect of puffing on nutritional components of soybean meal Puffing has a certain effect on the chemical components of soybean meal, but the loss of nutritional components is small. Puffing can significantly improve its structure and make it easier to digest and absorb. The effect of puffing on nutritional components of soybean meal was studied. The results showed that the content of crude protein decreased slightly and some amino acids were lost before and after puffing, but the digestibility of crude protein increased obviously.
