Feed of replacement gilts during perinatal period

Abstract

The invention belongs to the field of pig feed and discloses feed of replacement gilts during the perinatal period. The feed is characterized by comprising the following components in parts by weight: 55-60 parts of corns, 20-24 parts of soybean meal, 5.5-6.9 parts of DDGS, 1.3-2.2 parts of wheat bran, 5-10 parts of full-fat rice bran, 0.7-1.2 parts of soybean oil, 1-1.3 parts of imported fish meal, 0.9-1.1 parts of calcium powder, 1.0-1.2 parts of calcium hydrogen phosphate, 0.2-0.5 part of lysine sulfate, 0.4-0.5 part of edible salt, 0.1-0.2 part of choline chloride, 0.2-0.3 part of a vitamin premix, 0.2-0.3 part of a microelement premix and 0.05-0.06 part of a mould inhibiter premix. The feed can be used for promoting physical growth of the replacement gilts, alleviating the primiparous stress of the replacement gilts, improving the food intake of the replacement gilts in the early stage of lactation period, and enhancing the disease resistance of the replacement gilts during the perinatal period.

Description

technical field [0001] The invention belongs to the field of pig feed, in particular to a perinatal feed for gilts. [0002] Background technique [0003] At present, my country's pig industry is transforming into large-scale, intensive, and specialized production methods. Sow feeding and management is a key link in pig production. Among them, the perinatal period (7 days before and after delivery, a total of 14 days) for gilts Feeding management is an important key point. The dietary nutrition level of gilts during the perinatal period not only directly affects the feed intake of gilts during lactation and the performance of suckling piglets; Sow update knocks out turnover rate. [0004] Gilts are fed differently than sows and their nutritional needs differ from sows. Gilts are usually mated at 200 days of age and weigh about 120kg. However, the body of the gilt is immature, the body reserve is limited, the stomach and intestines are small, it is impossible to eat enou...

Problems solved by technology

[0005] However, the research direction on sows at home and abroad is concentrated on the lactation period, gestation period, and empty conception period of sows, and there are few studies on sows' perinatal period, especially the feed nutritional requirements of gilts during perinatal period.

This leads to the phenomenon of high primiparous stress, low feed intake, and poor disease resistance in the gilts during the perinatal period, and the phenomenon of short service life and high elimination rate of the gilts.
