A compound premixed feed for sows suitable for late pregnancy

Abstract

The invention discloses a sow compound premix feed suitable for sow in later stage of pregnancy. The sow compound premix feed is composed of the following components in parts by weight: 200-300 parts of expanded soybean meal, 80-200 parts of fish meal, 180-220 parts of bean pulp, 200-300 parts of beer yeast, 120-150 parts of calcium hydrogen phosphate, 100-200 parts of stone powder, 20-30 parts of lysine, 10-30 parts of methionine, 15-35 parts of threonine, 60-100 parts of compound trace elements, 12-20 parts of decavitamin, 100-150 parts of oligopeptide, 0.5-1 part of enzyme preparation, 1-2 parts of probiotics, 1-2 parts of feed preservative, 1-2 parts of magnesium sulfate, 4-5 parts of zinc methionine and 3-4 parts of chromium methionine. The sow compound premix feed suitable for sow in the later stage of pregnancy disclosed by the invention can be adapted to the metabolic mode of sow in the later stage of pregnancy, improve the sow endocrine, promote rise of blood sugar and ketone body levels and enhance the placental function to ensure that a fetus can obtain enough nutrients from the female parent so as to ensure the normal development of the fetus and promote the fetal growth.

Description

technical field [0001] The invention relates to a compound premixed feed suitable for sows in late pregnancy. Background technique [0002] At present, with the rapid development of the breeding industry in the direction of scale and standardization, the scale of sows raised by professional farmers is getting larger and larger, but the problem of raising pregnant sows has always been a problem that farmers do not pay much attention to. On the one hand, the majority of farmers clearly know the importance of pregnant sows, and know that the feeding level of pregnant sows determines the litter size and litter weight. On the other hand, they do not know how to raise sows, especially in the late stage of pregnancy. Sows at the first stage of life directly determine the weight of newborn piglets. However, traditional breeding always feeds traditional lactating sow feed in the later stage, without considering the difference in physiological characteristics between late pregnancy a...

AI Technical Summary

Problems solved by technology

However, traditional breeding always feeds traditional lactating sow feed in the later stage, without considering the difference in physiological characteristics between late pregnancy and lactation, and also does not consider the negative impact of lactation feed on the physiology and production of pigs in late pregnancy

In addition, most of the traditional full-price compound feeds are granular compound feeds, which are unreasonable in nutrition, inconvenient to use, and high in breeding costs.
