Embodiment 1

[0017] Example 1: Preparation of feed additive premix.

[0018] Weigh 25 parts of chitosan oligosaccharide, 200 parts of fructooligosaccharide, 400 parts of yeast cell wall, 20 parts of folic acid, 40 parts of vitamin E, 150 parts of 50% choline chloride, 165 parts of maltodextrin, and fully mixed to obtain feed additives premix. The chitosan oligosaccharide is obtained by hydrolysis of chitosan, the fructo-oligosaccharide is extracted from Jerusalem artichoke, the yeast cell wall is obtained by the yeast fermentation product, and 50% choline chloride is 50% corncob provided by Shandong Enbei Technology Co., Ltd. choline chloride.

Embodiment 2

[0019] Example 2: Effects of feed additive premix on sow milk quality and piglet growth performance.

[0020] The feed additive premix prepared in Example 1 was selected and added to the full-price feed in an amount of 2kg per ton of feed. Sows were fed feed containing this feed additive premix 28 days before farrowing. During gestation, according to the principle of weight control, the food intake was restricted, and the piglets were fed ad libitum during lactation until the piglets were weaned on the 21st day.

[0021] 40 sows with similar parity and body size were selected and randomly divided into two groups. The first group is the control group, with 20 sows, fed with common full-price feed; the second group is the experimental group, with 20 sows, fed with the full-price feed containing the premix described in Example 1.

[0022] The colostrum of the two groups of sows was collected for component analysis, and the routine milk analysis and the analysis of free sugar ch...

Abstract

The invention relates to a special feed additive premix for sows capable of improving sows' milk. Prepared by mixing cell wall (20%-40%), folic acid (2%-3%), vitamin E (3%-5%), 50% choline chloride (10%-15%) and carrier; The special feed additive premix for sows is added to the complete feed at a ratio of 0.1% to 0.5%. The active ingredients of the premix in the present invention are natural products or microbial products, and have the characteristics of high safety, no residue and no side effects. The special feed additive premix for sows can significantly increase the lactation volume of sows, improve the nutritional content of sow milk, thereby reducing the incidence of diarrhea in piglets, improving the survival rate and weaning weight of piglets; it can also improve constipation in sows, increase the Improve pig immunity and prolong the utilization period of sows.

Description

technical field [0001] The present invention relates to sow feed, in particular to a sow feed additive premix, in particular to a feed additive premix for improving milk oligosaccharide in sow milk and a method of using the same. Background technique [0002] At present, the vast majority of large-scale pig farms in my country are self-propagating and self-raising. The health level, survival rate and growth performance of piglets are one of the important factors limiting their production level. Lactation period is the peak period of piglet mortality. More than 90% of piglet deaths occur during lactation period, especially the increase in piglet mortality and physical decline caused by diarrhea is a serious problem. The health level and growth status of piglets during lactation directly affect the entire production process in the later period. If piglets show stunted growth, small size or diarrhea during lactation, they will show slow growth from weaning to slaughtering. The...
