Post-conceptual-age fetus-growth feed for sows in late pregnancy and preparation method thereof

Abstract

The present invention provides a post-conceptual-age fetus-growth feed for sows in late pregnancy. The post-conceptual-age fetus-growth feed comprises the following components in parts by weight: 45.3parts of corn, 6 parts of wheat middling, 10 parts of soybean meal, 5 parts of expanded soybeans, 12.5 parts of bran, 10 parts of beet pulp, 4 parts of bean skin, 1.5 parts of imported fish meal, 1.5parts of soybean oil, 0.7 part of calcium hydrogen phosphate, 1.1 parts of calcium carbonate, 0.4 part of sodium chloride, 1 part of a trace element vitamin premix, 0.12 part of lysine, 0.02 part ofmethionine, 0.05 part of threonine, 0.15 part of choline chloride, 0.02 part of vitamin E, 0.06 part of vitamin C, 0.05 part of beer yeast powder, 0.05 part of yeast, 0.3 part of potassium chloride, 0.01 part of L-carnitine, and 0.2 part of saccharomyces cerevisiae cell wall. The present invention also provides a preparation method of the feed. The feed can meet rapid growth needs of fetuses in the late pregnancy and can also satisfy development of mammary gland in the late pregnancy.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a tire-tapping feed for late-pregnancy sows and a preparation method thereof. Background technique [0002] China's pork consumption exceeds one-half of the world's total, but the level of pig breeding is far behind that of developed countries in Europe and the United States. For example, in 2012, the average number of sows born alive in China was 14.5, while Denmark's was 28.8 in the same period. If it catches up with Denmark In terms of pig raising level, China can save 20 million sows every year. At present, the feed on the market only emphasizes the nutrition of piglets, ignoring the importance of sow nutrition. This fragmented nutrition supply mode restricts the realization and improvement of the overall production performance of pig farms. [0003] According to the growth and development characteristics of pregnant sows and the law of embryo deposition, the entire pregnancy p...

AI Technical Summary

Problems solved by technology

[0007] 1. High embryonic mortality of sows and low litter size

[0008] 2. Leading to overfeeding of pregnant sows, thus A. affecting the development of mammary gland cells of sows in late pregnancy; B. affecting the feed intake of sows after delivery and during lactation, thus affecting milk; C. long labor process of sows, The incidence of dystocia increases, and the number of stillbirths increases; D. The ovaries of sows are severely fattened, and their development is hindered, which will affect the next estrus of sows
