Feed formula applied to breeding boars at different propagation and growth phases

Abstract

The invention discloses a feed formula applied to breeding boars at different propagation and growth phases The feed formula comprises a piggy phase feed, a fattening phase feed and a sow feed, wherein the piggy phase feed comprises a child care early stage feed and a child care later stage feed; the fattening phase feed formula comprises a porket feed, a shoat feed, a hog I phase feed and a hog II phase feed; and the sow feed comprises a backup sow feed, a pregnant sow feed and a lactated sow feed. Through the adoption of the feed formula disclosed by the invention, piggies fed with piggy phase feed are red in skin, bright in hair, free from diarrhoea and high in growing speed, and the feed is good in palatability, and high in digestibility; the breeding boars fed with the fattening phasefeed are high in growing speed, low in feed conversion rate, and low in meat making cost; the backfat of sows fed with the backup sow feed and the pregnant sow feed can be well adjusted, so that thesows are free from astriction, fertilized eggs are high in implantation speed, and the number of differentiated ovarian follicles of the sows is large; and the postnatal sows fed with the lactated sowfeed is sufficient in milk, and high in seven-day estrus rate, and the food consumption of suckling pigs is high.

Description

technical field [0001] The invention belongs to the technical field of a breeding method for cultivating high-quality breeding pigs by using scientific methods, and in particular relates to a feed formula applied to different growth stages of breeding pigs. Background technique [0002] In the breeding and breeding process of breeding pigs, in the growth period, fattening period and sow stages of breeding pigs and different growth periods, their growth and development characteristics and nutritional needs are different, and the focus of attention and strengthening is also completely different. . For example, the growth period strengthens the development of growth potential, while the fattening period focuses on the quality and safety of meat. Sows need to consider nutrition during pregnancy and postpartum lactation. The selection is very different, and the feed in the prior art is difficult to achieve the stable transition of the quality of the products in each stage. [0...

For example, the growth period strengthens the development of growth potential, while the fattening period focuses on the quality and safety of meat. Sows need to consider nutrition during pregnancy and postpartum lactation. The selection is very different, and the feed in the prior art is difficult to achieve a stable transition of product quality in each stage

[0003] At present, most of the breeding enterprises in the existing technology are not clear about the selection of feed at di
