Embodiment

[0023] 1. Formulated feed:

[0024] a. Preparation of feed for pregnant sows: 400kg of first-grade corn, 80kg of American ddgs, 112kg of bran, 190kg of Australian barley, 90kg of washed rice bran, 80kg of 43% soybean meal, 4.5kg of salt, 1kg of baking soda, 1.5kg of sodium bicarbonate, Stone powder 14kg, calcium hydrogen phosphate 8kg, glucose 10kg, 98.5% lysine 2.1kg, 50% choline chloride 1.3kg, 33% ethoxyquinoline 0.5kg, phytase 0.1kg and 0.5 pregnancy premixed feed 5kg Mix and set aside.

[0025] Pregnant sow feed: solve the problems of fetal nutrition, birth weight, and sow constipation. Targeted problems: feed nutrition, raw material structure, anti-constipation.

[0026] b. Prepare feed for lactating sows: take 465kg of first-grade corn, 30kg of bran, 96kg of Australian barley, 70kg of washed rice bran, 100kg of 43% soybean meal, 40kg of fermented soybean meal, 118kg of puffed soybean (full fat), 20kg of imported fish meal, sodium chloride 4kg, stone powder 12kg, calc...

Abstract

The invention relates to a feeding method for sows from pregnancy to parturition. The method comprises the following steps: preparing feed for sows from pregnancy to parturition and preparing nursing sow feed and restricting feed to pregnant sows; feeding in all following stages including weaning and breeding, feeding in a short term (estrualization), 7days after breeding, 7-100 days after breeding, 95 days after pregnancy to 112 days and sow delivery. The feeding method for sows from pregnancy to parturition has the following beneficial effects: by preparing dedicated feeds for pregnant sows and nursing sows, the sows are processed in different periods; special-purpose microecologics and preventative heat stress can effectively prevent constipation; feed with high content of energy, proteins and unsaturated fatty acid enable sow milk to be sufficient; full nutrition and reduction in weightlessness of a lactation period help promote oestrus of sows; by the method for feeding, a sow can deliver more than 10 piglets weighted average at 1.5 kilograms; after 28 days of weaning, the individual weight of each sow can be up to 8 kilograms; and estrus rate of the piglets within 5 days of sows is up to more than 90%.

Description

technical field [0001] The invention relates to a breeding method, in particular to a feeding method for sows from pregnancy to farrowing period which is improved by preparing special feed. Background technique [0002] In the process of pig farming, the feeding of sows is very important. High conception rate of sows, large litter size and high lactation survival rate are the key to improving the economic benefits of farms. In addition to being affected by the age and environmental conditions of the pigs, improper feeding will cause the sows to be too fat and often lead to infertility in breeding. If the sows are too thin, the sows will produce fewer mature eggs, resulting in irregular estrus. Specifically, the feeding before mating affects the development, quality and quantity of sow eggs, the feeding of sows in the early pregnancy after mating affects the number of embryos that survive in the early stage, and the feeding in the middle stage of mating affects the normal de...
