Nutrients requirements for growth of pigs

The nutrients needed by pigs are crude protein, carbohydrates, fat, vitamins, minerals (including macro and trace elements) and water. Under stocking conditions, pigs can obtain a small amount of minerals and vitamins by eating green fodder and mud, but in large-scale cement captivity, these nutrients must be obtained through feed except water. In compound feed, corn, soybean meal, bran and other grain are usually used.

Feed ingredients commonly used for pigs

1. Corn: Corn is the main energy supplement in feed industrial. When preparing pig feed, corn is used as the main body of the ratio, and a variety of nutritious feed balances mixture with it. Since corn contains more unsaturated fatty acids, the ground corn meal is prone to rancidity and deterioration, and is not suitable for long-term storage; newly marketed corn has high moisture content and is prone to mildew during storage, which should be storage perfectly.

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 excessive fat and constipation in middle pigs and pregnant mothers. The pig feed can account for about 20%, and the lactating sow's 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 and not more than 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.

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 finishing 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.
