Compound feed for improving immunity of piglets

Abstract

The invention discloses a compound feed for improving immunity of piglets. The compound feed is prepared from the following raw materials in parts by weight: 40-50 parts of oat flour, 20-30 parts of shrimp head meal, 4-6 parts of soybean oil, 20-30 parts of abandoned bean sprouts, 8-16 parts of soybean powder, 10-20 parts of straw powder, 6-12 parts of brown rice flour, 10-20 parts of sweet sorghum, 15-25 parts of earthworms, 10-20 parts of semen euryales, 20-40 parts of a vegetable protein additive, 0.2-0.4 parts of zinc chloride, 0.1-0.2 parts of potassium chloride, 4-8 parts of an attractant, 0.2-0.4 of a pectinase preparation, 0.1-0.2 parts of a cellulase preparation, 0.3-0.5 parts of a phytase preparation and 6-10 parts of a coating agent, wherein the coating agent is prepared from cyclodextrin and modified fibroin in a weight ratio of (2-4):(4-6); modified fibroin is prepared with the following process: dissolving fibroin in a lithium thiocyanate solution, performing stirring, performing dialyzing to remove lithium thiocyanate, adding allyl polyethylene glycol ether, mixing the mixture uniformly, adding ethylene glycol and performing stirring to obtain the modified fibroin.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a compound feed for improving piglet immunity. Background technique [0002] Piglets refer to suckling pigs aged 10 to 70 days after weaning, and weaning is another stress for piglets after birth, and their eating and nutritional habits will change, and the physiological functions of piglets at this time are not fully developed At the same time, the body's immunity is not perfect, the digestion and absorption ability is poor, the resistance to germs and the adaptability to environmental changes are poor, and diarrhea and growth stagnation often occur during feeding. The traditional feed at this stage is generally premixed with protein material and additives. As a result, the palatability is poor, the feed intake of piglets is small, the weight gain of piglets is slow after eating, and the immunity is weak, so they cannot effectively resist germs.
