Piglet birth weight increasing feed for sows at gestation later stage

Abstract

The invention discloses a piglet birth weight increasing feed for sows at the gestation later stage. The piglet birth weight increasing feed comprises the following components in parts by weight: 45-50 parts of corn, 3-8 parts of wheat middlings, 8-15 parts of soybean meal, 3-8 parts of puffed soybeans, 8-15 parts of bran, 8-15 parts of beet pulp, 3-8 parts of bean cream skim, 1-3 parts of imported fish meal, 1-3 parts of soybean oil, 0.6-1.5 parts of dicalcium phosphate, 0.8-1.5 parts of stone powder, 0.2-0.5 part of sodium chloride, 1 part of a trace element vitamin premix, 0.1-0.3 part of lysine, 0.02-0.08 part of methionine, 0.05-0.12 part of threonine, 0.05-0.2 part of choline chloride, 0.01-0.03 part of vitamin E, 0.03-0.08 part of vitamin C, 0.05 part of beer yeast powder, 0.05 partof microzyme, 0.3 part of potassium chloride, 0.01 part of L carnitine and 0.2 part of saccharomyces cerevisiae cell walls. The piglet birth weight increasing feed disclosed by the invention can meetrequirements of foetuses for quick growth at the gestation later stage, and can also meet the requirements of the sows at the pregnancy later stage for mammary gland development.

Description

technical field [0001] The invention relates to the field of feed, in particular to a tire-tapping feed for late-gestation sows. Background technique [0002] China's pork consumption is more than half of the world's, but the level of pig breeding is far behind 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 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 period is divided into early pregnancy (empty pregnancy - 8...

AI Technical Summary

Problems solved by technology

[0005] Existing nutrition misunderstandings of pregnant sows: A. At present, gilt feed or feed for large pigs and lactating sows are used to feed sows in late pregnancy, which cannot meet the nutritional needs of sows in late pregnancy; B. Unreasonable feed preparation, such as fiber The level is too low; C. The recommended feeding program is not strictly implemented

[0006] The traditional gilt feed, large pig feed or lactating sow feed has the following hazards in feeding sows in late pregnancy: 1. High embryonic mortality and low litter size

2. Leading to overfeeding of pregnant sows, which affects the development of mammary gland cells in late pregnancy; affects the feed intake of sows after delivery and during lactation, thereby affecting milk; sows have a long labor process, increased incidence of dystocia, and stillbirth The number of sows increased; the ovaries of sows were severely fattened, and their development was hindered, which would affect the next estrus of sows
