Compound premix feed for lactating sows and preparation method thereof

Abstract

The invention discloses a compound premix feed for lactating sows and a preparation method of the compound premix feed. The compound premix feed is mainly prepared from the following raw materials inparts by weight, 25-30 parts of rice hull powder, 15-20 parts of peanut skin, 15-20 parts of brown sugar, 10-15 parts of calcium hydrophosphate, 8-10 parts of stone powder, 6-8 parts of zeolite powder, 0.4-0.8 part of compound vitamin, 1.5-2.5 parts of composite trace elements, 3-5 parts of an acidifying agent, 3-5 parts of edible salt, 1.5-2.5 parts of lysine, 0.5-1 part of choline chloride, 0.5-1 part of a composite microecological preparation, 0.4-0.6 part of a mould adsorbent, 0.2-0.4 part of an antioxidant, 0.2-0.4 part of soy isoflavone and 0.08-0.12 part of phytase. The invention also discloses a method for preparing the feed. The feed is good in blood enriching effect and capable of effectively promoting sow feeding, improving sow lactation performance and immunity, increasing milkyield, promoting piglet growth and preventing and treating sow anemia and piglet diarrhea.

Description

technical field [0001] The invention belongs to the technical field of pig feed, and in particular relates to a compound premixed feed for lactating sows and a preparation method thereof. Background technique [0002] Compound premixed feed refers to the uniformly stirred mixture of one or more additive raw materials and carrier or diluent, also known as additive premix or premix, the purpose is to facilitate the uniform dispersion of trace raw materials in a large amount of compound feed . At present, low feed utilization rate, anemia, constipation, postpartum fat loss in lactating sows, and diarrhea in piglets are common in pig production. From the day after farrowing to weaning, more than 80% of sows are anemic at different stages, especially sows after parity 2. Sows with severe anemia have thin body, pale skin, difficulty in estrus, and insufficient milk, which can easily lead to poor vitality, low survival rate, and low weaning weight of piglets. In addition to iron...

Problems solved by technology

Existing sow feed simply supplements inorganic iron to achieve blood enrichment for sows. The absorption and utilization rate is low, the palatability is poor, and the blood enrichment effect is poor. Adding antibiotics to improve the body's immunity is prone to drug resistance, resulting in antibiotic residues and environmental pollution.
