Problems solved by technology

[0006] Therefore, in view of the technical problem that the nutritional balance of breeding sow feed cannot reach the ideal state in the prior art, thereby affecting the technical problems of sow litter size and piglet birth weight, we have developed sow feed formula and different formulations of feed for sows. In the study of the influence of reproductive ability, it was surprisingly found that the crude fiber content in the feed was limited to 5-6.5%, and the content and mutual ratio of lysine and threonine were set within a reasonable range, while The content of other amino acids meets the NRC2012 standard, and the nutritional balance of the feed is high, which can effectively improve the farrowing performance of sows, increase the number of live piglets, and increase the birth weight of piglets

Embodiment 1

[0052] Embodiment 1 Feeding of foreign binary (long × large) pigs

[0053] Select 46 foreign binary (long × large) pigs with similar gestational age and the same mating age (can be purchased from Shanghai Breeding Pig Farm or Shanghai Xiangxin Livestock and Poultry Co., Ltd.), and divide them into the experimental group (24 pigs) and the control group (22 heads), using the same feeding methods, disease prevention and control measures and other feeding and management measures when raising sows in the same conventional manner, using the feeds of the experimental group and the control group shown in Table 1 to raise respectively, from 5 days before mating to gestation Feed with pre-feeding for 89 days, and feed with post-feeding from 90 days of pregnancy to the end of lactation (25 days after delivery). Among them, the pre-feed and post-feed used in the experimental group are respectively the feed for sows in the early stage of reproduction and the feed for sows in the later stag...

Embodiment 2

[0064] The raising of embodiment 2 Shanghai white pigs

[0065] Select 42 Shanghai White pigs with similar gestational age and same mating age, and divide them into experimental group (21 pigs) and control group (21 pigs). Management measures, use the feed of the experimental group and control group shown in Table 1 to feed respectively, use the pre-feed from 5 days before mating to 89 days of pregnancy, and use the post-feed from 90 days of pregnancy to the end of lactation (postpartum 28 days). Among them, the pre-feed and post-feed used in the experimental group are respectively the feed for sows in the early stage of reproduction and the feed for sows in the later stage of reproduction prepared according to the mathematical model of the early stage and the later stage of the present invention. The pre- and late-stage feeds used in the control group were common original field feeds.

[0074] The raising of embodiment 3 Meishan pigs

[0075] Select 100 Meishan pigs with similar gestational age and same mating age, divide them into experimental group (50 heads) and control group (50 heads), adopt the same feeding methods, disease prevention and control measures and other feeding management as when sows are raised conventionally Measures, use the feed of the experimental group and control group shown in Table 1 to feed respectively, use the pre-feeding from 5 days before mating to 89 days of pregnancy, and use the post-feeding from 90 days of gestation to the end of lactation (postpartum 30 days). Among them, the pre-feed and post-feed used in the experimental group are respectively the feed for sows in the early stage of reproduction and the feed for sows in the later stage of reproduction prepared according to the mathematical model of the early stage and the later stage of the present invention. The pre- and late-stage feeds used in the control group were c...

Abstract

The present invention discloses a feed for sows in a pre-breeding period. The pre-breeding period is 5 days before hybridization to 89 days of pregnancy. The raw material ratios and nutrient levels of the feed for the sows in the pre-breeding period are in accordance with a pre-period mathematical model. The present invention also discloses a feed for the sows in a post-breeding period. The late-breeding period is 90 days of pregnancy to the end of lactation. The raw material ratios and nutrient levels of the feed for the sows in a late-breeding period are accordance with a post-period mathematical model. In the feed for the sows in the pre-breeding period and the feed for the sows in the post-breeding period, a crude fiber content is 5-6.5%. At the same time, the contents and ratios of lysine and threonine are set in a reasonable range. The feed can meet the requirement of the breeding sows for the crude fibers, at the same time avoids inadequate or uneven nutrition intake of the sows caused by too high crude fiber contents, and can effectively improve the breeding capacity of the sows and increase the number of live piglets and the birth weight of the piglets.

Description

technical field [0001] The invention belongs to the technical field of sow breeding, and in particular relates to a feed for sows in the early stage of reproduction and a feed for sows in the later stage of reproduction. Background technique [0002] In recent years, the effect of dietary fiber on sow fertility and health has received widespread attention. Dietary fiber refers to the combination of non-starch polysaccharides and lignin in plant foods that cannot be digested by digestive enzymes in the gastrointestinal tract, but can be partially fermented and utilized by certain microorganisms in the large intestine. Dietary fiber can be divided into soluble dietary fiber and insoluble dietary fiber according to solubility. Soluble dietary fiber refers to the part of fiber that is soluble in water and its aqueous solution can be reprecipitated by 4 times 95% ethanol, mainly storage substances and secretions in the cell wall, and also includes microbial polysaccharides and s...
