Problems solved by technology

[0003] Reserve pigs are the basis for the renewal of breeding herds. The growth and development of reserve pigs has a certain impact on production performance. Although reserve pigs have many similar characteristics with growing and finishing pigs, they cannot adopt the same nutrient supply, feeding methods and management measures.

Embodiment Construction

[0020] The present invention will be described in further detail below by means of specific embodiments:

[0021] Experimental method: 450 Landrace sows of reproductive age with similar age and body weight were selected and randomly assigned to 9 groups with 50 sows in each group. Except that the feed is different in each group, other treatment conditions and management conditions are the same, which are traditional management conditions in the prior art. After feeding the sows for 3 months, these sows were subjected to simultaneous estrus technology and timed insemination technology, and after about 4 months, the number of litters in each group and the average weight of newborn piglets were counted.

[0022] The first control group: 3 months before pregnancy and 2 months after pregnancy, fed Urumqi Zhengda 156 pregnant sow concentrate; from 2 months of pregnancy until delivery, fed Urumqi Zhengda 157 lactating sow concentrate.

[0023] The feed formula of the second group an...

Abstract

The invention belongs to the field of livestock feed, and particularly discloses feed capable of increasing farrowing quantity of sows. The feed comprises, by weight, 34-40 parts of corn flour, 15-18 parts of wheat bran, 15-18 parts of soybean meal, 12-15 parts of bone powder, 5-8 parts of sterile fly maggot, 4-6 parts of barley pest, 15-18 parts of spinach, 8-12 parts of Cucurbita kangua, 3-5 parts of Fructus ziziphi jujubae, 2-4 parts of Japanese ginseng root and 2-4 parts of Stachys oblongifolia. By taking the feed, average farrowing quantity of multiparous landrace sows each birth can reach more than 13.

Description

technical field [0001] The invention relates to the field of livestock feed, in particular to a feed for improving the litter size of sows. Background technique [0002] The main purpose of raising breeding pigs is to breed piglets and provide pig sources. The annual productivity of sows refers to the number of weaned piglets provided by a sow within a year. There are many factors that restrict the annual productivity of sows, the most important being the number of litters per litter and the number of litters per year. [0003] Reserve pigs are the basis for the renewal of breeding herds. The growth and development of reserve pigs has a certain impact on production performance. Although reserve pigs have many similar characteristics with growing and finishing pigs, they cannot adopt the same nutrient supply, feeding methods and management measures. The nutritional level in the diet should vary according to the growth stage of the back-up pigs. Pay attention to the ratio of ...
