Pregnancy fodder for improving farrowing performance of sows and feeding management method

Abstract

The invention discloses pregnancy fodder for improving farrowing performance of sows and a feeding management method. The method comprises the steps that according to different nutritional requirements of all periods of the pregnant sows, regulation of embryo implantation, fetal development and fatness conditions of the sows is fully considered, the pregnancy period of the sows is divided into three periods, the fodder and feeding amount of each period are refined, and the farrowing performance of the sows is improved. The method specifically comprises the steps that pregnancy fodder fed in the early gestation stage, pregnancy fodder fed in the middle gestation stage and pregnancy fodder fed in the later gestation stage are different, and contain NCG; the overall fatness conditions of thesows, namely the back-fat thicknesses are controlled to be 12-17 mm and recorded, and the sows which are too fat and too slim are marked by a fatness adjusting clamp; according to the fatness conditions, the feeding amount of the sows is adjusted, the feeding amount for the sows which are too fat is reduced, and the feeding amount for the sows which are too slim is increased; after the fatness conditions are adjusted to reach the standard, the fatness adjusting clamp is timely removed, and feeding is conducted according to the normal fodder amount. By means of the feeding management method forthe pregnancy fodder, the uniformity of piglets can be improved, the still birth rate of the piglets is reduced, the litter size and the litter weight of the piglets are increased, the survival rateof the piglets is increased, and the growth vigor of the piglets in the later period is improved.

Description

technical field [0001] The invention belongs to the technical field of feed, and relates to a feed for sows during pregnancy (abbreviated as pregnancy feed) and a feeding management method thereof, in particular to a pregnancy feed and a feeding management method for improving the farrowing performance of sows. Background technique [0002] The breeding efficiency in my country is low. At present, the P SY (that is, the number of weaned piglets provided per sow) in my country's large-scale pig farms is generally 20-25, while developed countries such as Europe and the United States have more than 30. Compared with this, there are still A certain gap. With the introduction of foreign high-yielding breeds, traditional breeding methods and nutrition can no longer meet the needs of sows. To develop their genetic potential, how to increase the number of sows born and reduce the mortality of piglets has become the most urgent problem to be solved. [0003] Sows are the driving forc...

AI Technical Summary

Problems solved by technology

[0005] At present, in the market, the nutrition and management of pregnant sows have not been paid attention to by everyone. It is common that only one level of feed is fed throughout the pregnancy. There are no strict restrictions on the amount of feed, and no adjustments have been made to the regulation of sow body condition, resulting in low sow births and high piglet mortality

It can be seen that traditional feeding management methods and nutrition can no longer meet the needs of sows
