Pregnant sow nursing feed and preparation method thereof

Abstract

The invention provides a pregnant sow nursing feed and a preparation method thereof, and relates to the technical field of feed processing. The nursing feed is prepared from the following raw materials in parts by weight: 20-40 parts of corns, 12-16 parts of pumpkin, 20-26 parts of wheat bran, 18-22 parts of soybeans, 4-6 parts of fish meal, 2-4 parts of garlic, 10-12 parts of a traditional Chinese medicine extracting solution, 1-3 parts of choline chloride, 3-4 parts of selenium-enriched yeast, 2-4 parts of a vitamin mixture, 2-3 parts of protease, 0.2-0.6 part of a trace element mixture, 4-6parts of oligosaccharide, 1-2 parts of sodium chloride and 0.8-1.2 parts of dibasic calcium phosphate. The defects in the prior art are overcome, various nutrient substances required by sows during pregnancy can be provided effectively, the immunity of the pregnant sows is enhanced, the abortion rate and the stillbirth rate of the sows are reduced, the survival rate of newborn piglets is high, the body weight of the piglets is increased quickly, and the breeding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a nursery feed for pregnant pigs and a preparation method thereof. Background technique [0002] Pork is the main non-staple food in people's daily life. It is sweet and flat in taste, rich in protein and fat, carbohydrates, calcium, iron, phosphorus and other ingredients. The meat fiber is soft, and the meat tastes delicious after cooking. [0003] With the continuous improvement of people's living standards, there are more and more requirements for the quantity of pork. In the pig industry, sow productivity is critical. However, at present, due to the limitation of feeding technology, the production capacity of sows is generally low. During pregnancy, the number of piglets born alive is low, and the birth weight of piglets is low, resulting in a small number of pigs in stock and slow production speed, which seriously limits the production capacity of sows. The develo...

AI Technical Summary

Problems solved by technology

[0004] Generally, pregnant pigs need to maintain phosphorus, calcium and protein intake during pregnancy, so most of the conventional pregnant pig feeds are supplemented with enough phosphorus, calcium and protein, but on this basis, although the development of piglets is guaranteed, it will greatly To a certain extent, the sows are too fat, which makes it difficult to give birth, and the survival rate of piglets cannot be guaranteed, and the infection rate of sows after pregnancy continues to increase
