2. Wheat bran: Wheat bran has a laxative effect. It should be avoided in suckling pig diets. Piglets and medium and large pigs can use 5-15%. Wheat bran is a good raw material for controlling overweight and constipation in middle pigs and pregnant mothers. The pig feed can account for about 20%, and the lactating sow feed should not exceed about 20%, so as not to have too low energy and affect the condition of lactation.
3. Soybean meal: The use of soybean meal in suckling pig feed should be restricted, not exceeding 25%, because the soybean antigen in soybean meal can cause diarrhea in suckling pigs and weaned piglets, and the use of a part of extruded soybeans will achieve better effects.
4. Cotton meal: The gossypol contained in cotton meal has a certain toxic effect on pigs, so the use of cotton meal should be controlled. Under normal circumstances, cotton meal should not be used in the diet for suckling pigs, piglets and sows, and no more than 6% of the diet for growing pigs and fattening pigs.
5. Rapeseed: The bitterness and astringency of rapeseed meal will affect the palatability and protein utilization, and hinder the growth of pigs. Therefore, it is best not to use rapeseed meal for suckling pig and piglet feed. It is advisable to add 3-5% to the diet of growing pigs, fattening pigs and sows.
6. Peanut meal (cake): Peanut meal is a good source of protein in pig feed. Pigs like to eat, but should not be fed more, generally not more than 15%, otherwise the fat of the pig body will become soft and affect the quality of the carcass.
7. Fishmeal: Fishmeal is an excellent feed material for suckling pigs and piglets. However, due to the high price, some farmers and feed factories use less and less fishmeal. When the cost permits, use as much fish meal as possible, which will help the performance of pig production.
