Nursing sow high-efficiency feed and preparation method thereof

Abstract

The invention provides a nursing sow high-efficiency feed and a preparation method thereof. Raw materials such as corn, white sugar, wheat bran, fish meal, soya bean meal, puffed soybean, feather meal, blood globulin powder, distillers dried grains with soluble (DDGS), soybean oil, vitamine, trace elements, an ionic equilibrium agent, a physiological regulator and the like are adopted, and the nursing sow high-efficiency feed is prepared by performing smashing, mixing, tampering, pelletizing and other processing on the raw materials. In the invention, the newest theory of the existing animal nutrition and feeding is taken as a basis and production practice is combined, thus the defects of the prior art are overcome. The high-efficiency feed has the following advantages: the current cultivation situation in the southern part of China, market requirements and the newest sow nutrition theory are combined, and maximization of productive potential of a nursing sow is taken as an aim, especially amino acid balance is considered, so that branched chain amino acid nutrition is enriched, the sow antistress capability is improved, and the palatability of the feed is improved; and the ionic balance of the feed is considered, high-quality feed raw materials are selected, and strict scientific processing is carried out, thus the milk production performance of the nursing sow can be greatly improved, finally the weight of weaning litter of suckling pigs is improved, and the market requirement is met.

Description

technical field [0001] The invention relates to the field of high-efficiency feed, in particular to a high-efficiency feed capable of improving the lactation performance of lactating sows and a preparation method thereof. Background technique [0002] The modern pig industry has undergone considerable development and has made great progress. In the pig industry, usually 70% of the cost comes from feed, and most of the great progress of my country's pig industry comes from the progress of pig nutrition research and practical technology, and a small part of the contribution comes from breeding technology. Because most of the three-way hybrid pigs that are raised in the largest scale in my country currently contain the blood of foreign breeds, the breeding field in my country basically adopts the method of introduction and cultivation as a supplement. In the field of nutrition research and practice, suckling piglets and growing-finishing pigs are the most in-depth and systemat...

AI Technical Summary

Problems solved by technology

[0004] At present, the following problems generally exist in the feeding and nutrition of lactating sows in my country: first, the feed intake is generally low, and the maximum lactation potential of lactating sows cannot be exerted, and most of them have fat loss; In high temperature and high humidity climates, the stress is very serious; thirdly, low nutritional levels are common, especially for high-yielding lactating sows. Fourth, most lactating sows lack the guidance of amino acid balance theory in feed preparation, and lack awareness of branched-chain amino acid nutrition; fifth, they lack systematic thinking in feed preparation and do not comprehensively consider the latest sow nutritional developments The relationship between nutrition and environment, nutrition and stress, etc., cannot maximize the potential of sows
