Concentrate feed capable of improving milkability of high-lean-meat hyperprolific sows and feeding method

Abstract

The invention relates to the technical field of animal feed, in particular to a concentrate feed capable of improving the milkability of high-lean-meat hyperprolific sows. The concentrate feed is prepared from, by mass, 35%-50% of emulsification cooperation fat, 1%-2% of brewer's yeast, 10%-20% of branched chain amino acid, 2%-5% of bioactive glycoside, 5%-10% of glucose, 5%-10% of potassium chloride, 1%-2% of vitamin C and 20%-40% of expanded corn flour. The concentrate feed can improve the milkability of the lean-meat hyperprolific sows, enable the sows to generate more high-quality milk and increase the weaning weight and survival rate of suckling pigs and has the better flexibility when the sows are additionally fed on the concentrate feed while feeding.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a concentrated feed and a feeding method for improving the lactation ability of lean-meat high-yielding sows. Background technique [0002] Modern lean high-yielding sows have more litters, but feed intake is often insufficient due to selection orientation. When the nutrient concentration of the feed is low, it is easy to cause insufficient nutrient supply and affect the lactation ability of the sow; when the nutrient concentration of the feed is high, it is difficult to balance some key nutritional factors at the same time due to the cost of the formula, which will also affect the lactation ability of the sow. The quality of sow milk during lactation directly determines the health, growth and development of piglets. Therefore, to improve the daily gain and survival rate of piglets during lactation, the key is to improve the lactation ability of sows. Studies have shown that...

Problems solved by technology

Branched-chain amino acids, especially valine, are very important for the growth and development of mammary glands. They are the limiting amino acids in high-protein diets for sows. However, due to cost considerations, branched-chain amino acids are not commonly used in production.
