Problems solved by technology

[0004] As the source of pig raising, sows are under tremendous production pressure and need to bear heavy loads such as pregnancy, childbirth, and lactation, which can easily cause potential physiological damage. The physical needs of sows are often unable to meet their physiological needs, which will have a very serious negative impact on the production potential of sows and the growth of subsequent suckling piglets

Embodiment 1

[0028] Intestinal regulation method of weaned piglets

[0029] As the matrix feed, the "Kesheng No. 1" piglet compound feed produced by Zhejiang Kesheng Feed Co., Ltd. is used, and the additive of the present invention is added to be formulated to contain: 1 gram of sodium butyrate, 0.5 gram of glutamine in every kilogram of compound feed gram. The compound feed contains 19.3% crude protein, 5.8% crude fat, 1.0% calcium, 0.5% available phosphorus, 1.5% lysine, and 0.9% methionine+cystine.

[0030] Application effect: taking no addition of sodium butyrate and glutamine as the basis control, after 28-day-old weaned piglets used the technical product of the present invention for 3 weeks, the diarrhea rate decreased by 41.7%; the number of E. coli in the jejunum was significantly reduced, and the number of lactobacillus Significantly elevated; plasma cell IgA in the jejunal mucosa + The content of duodenal content increased significantly; trypsin activity in duodenal content inc...

[0032] Intestinal regulation method of growing-finishing pigs

[0033] Use "Kesheng No. 3" growing-finishing pig compound feed produced by Zhejiang Kesheng Feed Co., Ltd. as matrix feed, and add the additive of the present invention, be mixed with in every kilogram of compound feed containing: sodium butyrate 1 gram, glutamic acid Amide 0.5 g. The compound feed contains 16.0% crude protein, 3400 kcal / kg digestible energy, 0.5% calcium, 0.2% available phosphorus, 1.0% lysine, and 0.4% methionine+cystine.

[0034] Application effect: with no addition of sodium butyrate and glutamine as the control, the 40kg three-way cross (Du × large × long) pigs used the technical product of the present invention for 2 months, the daily weight gain increased by 1.5%, and the feed-to-weight ratio The length of duodenal villi increased by 13.3%, the length of duodenal gland increased by 9.7%, and the rate of diarrhea decreased by 23%.

Embodiment 3

[0036] Sow intestinal regulation method

[0037] Use "Kesheng No. 6" sow compound feed produced by Zhejiang Kesheng Feed Co., Ltd. as the matrix feed, and add the additive of the present invention, be mixed with sow pregnancy feed, contain in every kilogram of pregnancy feed: sodium butyrate 1 grams, 0.5 grams of glutamine. The pellet feed contains 15.0% crude protein, 3400 kcal / kg digestible energy, 0.75% calcium, 0.35% available phosphorus, 0.75% lysine, and 0.40% methionine+cystine.

[0038]Use "Kesheng No. 8" sow compound feed produced by Zhejiang Kesheng Feed Co., Ltd. as matrix feed, and add the additive of the present invention, be mixed with sow feeding feed, contain in every kilogram of feeding feed: sodium butyrate 1 grams, 0.5 grams of glutamine. The compound feed contains 17.0% crude protein, 3400 kcal / kg digestible energy, 0.75% calcium, 0.35% available phosphorus, 0.9% lysine, and 0.45% methionine+cystine.

[0039] Application effect: Based on the control with...

Abstract

The invention discloses a feed additive, functional feed, and a preparation method and an application of the functional feed. The feed additive is composed of sodium butyrate and glutamine with the weight ratio of 2:1, and the feed additive is capable of adjusting balance of intestinal flora of pigs, improving intestinal morphology and enhancing intestinal canal immune functions; the functional feed is composed of matrix feed and the feed additive with the weight ratio of 1000:1.5; and the sodium butyrate and the glutamine are added into particle feed according to appropriate dosage, and the functional feed is fed to weaned pigs, growing-finishing pigs and sows so that health conditions of intestinal canals of the pigs can be obviously improved, diarrhea occurrence rates of piglets and the growing-finishing pigs are reduced, growing of the piglets and the growing-finishing pigs is promoted, and reproductive performances of the sows are improved.

Description

technical field [0001] The present invention relates to the field of regulating pig intestinal nutrient metabolism, specifically, the present invention relates to a feed additive for regulating the balance of pig intestinal flora, improving intestinal morphology, enhancing intestinal immune function, functional feed and its preparation method and application . Background technique [0002] Early weaning of piglets is one of the important means to improve the performance of sows in modern intensive pig production. Weaning at the age of 3 to 5 weeks is mostly adopted in China. Early weaning of piglets can shorten the lactation period of sows and reduce weight loss; after weaning, sows can be mated in time, thereby shortening the interval between litters and helping to improve the fertility of sows; in addition, early separation of sows can prevent sows from Pig crushed piglets and piglets infected by sow diseases are beneficial to improve the survival rate of piglets.
