Problems solved by technology

[0002] Lactating sows refer to pregnant sows that are in the lactation period after giving birth. If the supply of nutrients is slightly insufficient during the lactation period, it will not have a significant impact on lactation, but the sows must use weight loss to compensate, and the lactation sows lose weight It is a normal phenomenon, but if the weight loss is too large, it will affect the sow's next reproduction. Under normal feeding and management conditions, the weight loss of lactating sows generally does not exceed 15% of the sow's postpartum body weight. It will seriously affect estrus, ovulation and conception after weaning, and lead to a decrease in the survival rate of embryos in the next pregnancy

Embodiment 1

[0013] 65% of the total amount of high-quality corn, 15% of soybeans, 10% of rice, and 5% of barley are sent to a grinder to be pulverized into powder to obtain a mixed feed; 3% of the total amount of fish meal, Calcium carbonate with an amount of 1%, iodized salt that accounts for 0.5% of the total amount, multivitamins that account for 0.5% of the total amount, and the mixed feed are sent to the blender to mix evenly and then sent to the granulator for direct granulation, and then Send it to a dryer for drying. After drying, the feed for lactating sows is obtained. The particle weight is generally about 3 grams;

Abstract

The invention discloses a preparation method of feed for lactating sows, and belongs to the field of animal feed; and a formula used in the invention includes the following raw materials calculated inpercentages by weight: 65%-67% of high-quality corn, 13%-15% of soybeans, 10% of rice, 5% of barley, 3% of fish meal, 1% of calcium carbonate, 0. 5% of iodized salt and 0.5% of multi-vitamins. The feed for lactating sows is prepared by subjecting the raw materials to crushing, mixing, granulating. The feed for lactating sows is rich in nutrients, good in mouthfeel, capable of fully meeting the nutrition and lactation needs of the lactating sows and high in safety.

Description

technical field [0001] The invention belongs to the field of feed processing, in particular to a method for preparing feed for lactating sows. Background technique [0002] Lactating sows refer to pregnant sows that are in the lactation period after giving birth. If the supply of nutrients is slightly insufficient during the lactation period, it will not have a significant impact on lactation, but the sows must use weight loss to compensate, and the lactation sows lose weight It is a normal phenomenon, but if the weight loss is too large, it will affect the sow's next reproduction. Under normal feeding and management conditions, the weight loss of lactating sows generally does not exceed 15% of the sow's postpartum body weight. It will seriously affect estrus, ovulation and conception after weaning, and lead to a decrease in the survival rate of embryos in the next pregnancy. In order to reduce the weight loss of lactating sows, maintain a good body condition, produce more ...
