Embodiment 1

[0023] Sixty Large White×Yorkshire (LY) hybrid sows in the late gestation period (85 days) were randomly divided into 4 treatment groups according to parity and similar production level: control group; isomaltose oligosaccharide group (feed Add 0.5% isomalto-oligosaccharide, IMO group); Isomalto-oligosaccharide-Bacillus subtilis compound group (add 0.5% isomalt-oligosaccharide-Bacillus subtilis compound in the feed, IMO+K group); Maltose-Bacillus licheniformis compound group (add 0.5% isomaltooligosaccharide-Bacillus licheniformis compound to the feed, IMO+D group). Each treatment group had 15 replicates, and each replicate had 1 pig. The experiment started from the 85th day of pregnancy to the weaning of piglets (18 days after delivery). On the day of farrowing (within 1 hour after farrowing) and the 18th day after farrowing, the mixed milk samples were collected from the teats of the front, middle and back three milking areas respectively, and normal milk and colostrum were...

Embodiment 2

[0032] Eighty large white×Yorkshire (LY) hybrid sows in the late pregnancy (85 days) were randomly divided into 4 treatment groups according to parity and similar production level: control group; isomaltose oligosaccharide group (feed Add 0.5% isomalto-oligosaccharide, IMO group); Isomalto-oligosaccharide-Bacillus subtilis compound group (add 0.5% isomalt-oligosaccharide-Bacillus subtilis compound in the feed, IMO+K group); Maltose-Bacillus licheniformis compound group (add 0.5% isomaltooligosaccharide-Bacillus licheniformis compound to the feed, IMO+D group). There were 20 replicates in each treatment group, and one pig per replicate. The experiment started from the 85th day of pregnancy to the weaning of piglets (18 days after delivery). On the day of farrowing (within 1 hour after farrowing) and the 18th day after farrowing, the mixed milk samples were collected from the teats of the front, middle and back three milking areas respectively, and normal milk and colostrum wer...

Embodiment 3

[0041]Seventy Large White×Yorkshire (LY) hybrid sows in the late gestation period (85 days) were randomly divided into 5 treatment groups according to parity and production level: control group; isomaltooligosaccharide group (feed Add 0.5% isomalto-oligosaccharide, IMO group); Isomalto-oligosaccharide-Bacillus subtilis compound group (add 0.5% isomalt-oligosaccharide-Bacillus subtilis compound in the feed, IMO+K group); Maltose-Bacillus licheniformis compound group (add 0.5% isomaltose-oligosaccharide-Bacillus licheniformis compound in the feed, IMO+D group); Isomaltooligosaccharide-Bacillus licheniformis-Bacillus subtilis complex, IMO+D+K group). There were 14 replicates in each treatment group, with 1 pig in each replicate. The experiment started from the 85th day of pregnancy to the weaning of piglets (18 days after delivery). On the day of farrowing (within 1 hour after farrowing) and the 18th day after farrowing, the mixed milk samples were collected from the teats of t...

Abstract

The invention relates to a feed additive capable of improving the milk secretion property and oxidation resistant capacity of sows. The feed additive comprises the following components in parts by weight of 30-50 parts of isomaltooligosaccharide and 1-5 parts of bacillus subtilis (bacillus subtilis). The invention further provides a preparation method of the feed additive capable of improving themilk secretion property and oxidation resistant capacity of sows. The preparation method comprises the following steps of enabling the isomaltooligosaccharide to dissolve in water, then adding the bacillus subtilis and bacillus licheniformis, enabling the bacillus subtilis and the bacillus licheniformis to dissolve, performing uniform mixing, and performing drying so as to obtain the feed additive. The feed additive disclosed by the invention is a brand-new combined additive product, the milk secretion property and the oxidation resistant capacity of the sows can be obviously improved, the action effect of the feed additive is significantly improved than that of previous products, and the feed additive is also safe, high-efficient and stable.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a feed additive for sows and a preparation method thereof. Background technique [0002] With the development of modern animal husbandry, large-scale, intensive and modern pig raising has become a trend of today's development. In pig production, the most important factor that determines the production level and economic benefits of a pig farm is the reproductive performance of sows. Due to continuous genetic selection, the litter size and birth weight of sows are increasing continuously, and the lactation performance is also significantly improved to ensure that sows have sufficient milk to meet the growth of piglets. Breast milk is an important source of nutrition for suckling piglets. Colostrum is rich in immunoglobulins, which can enable piglets to obtain passive immunity. The growth rate and survival rate of piglets are closely related to the lactation performance of sows. The...
