However, the method of reducing skatole in pigs by adjusting the composition and content of pig diets is too dependent on the composition and ratio of diets, and the storage period of food is short. impact on health, and the effect achieved is not obvious

Embodiment 1

[0021] Divide 80 castrated boars with a body weight of 60.0±1kg into 4 groups A, B, C and D, with 4 replicates (pens) in each group and 5 pigs in each replicate, where A, B, and C are In the experimental group, 0.5%, 1% and 1.5% isomaltooligosaccharides were added to the complete feed of pigs respectively, and group D was the control group. One pig was drawn for each replicate at slaughter. Each group used the same basal diet, the formula of complete feed: 65% corn, 20% soybean meal, 10% wheat bran, and 5% premix.

[0022] In addition, 80 castrated boars with a body weight of 60.0±1kg were divided into 4 groups A', B', C' and D', with 4 replicates (pens) in each group and 5 pigs in each replicate. ', B', and C' are experimental groups, and 0.5%, 1% and 1.5% isomaltooligosaccharides were added to the pig's complete feed respectively, and group D is the control group. Four groups of boars were injected with glutamine dipeptide every three days. One pig was drawn for each repl...

Embodiment 2

[0033] Divide 100 castrated boars with a body weight of 60.0±1kg into 5 groups A, B, C, D and E, with 4 replicates (circles) in each group, and 5 pigs in each replicate, wherein A, B, C is the experimental group, 0.5%, 1% and 2% of lactic acid bacteria were added to the complete feed of pigs respectively, and groups C and D were the control group, and 1.5% of isomaltooligosaccharides were added to each of A, B, C and D. One pig was drawn for each replicate at slaughter. Each group used the same basal diet, the formula of complete feed: 65% corn, 20% soybean meal, 10% wheat bran, and 5% premix.

[0034] Another 100 castrated boars with a body weight of 60.0±1kg were divided into 5 groups A', B', C', D' and E', with 4 replicates (pens) in each group and 5 pigs in each replicate , where A', B', C' are the experimental groups, 0.5%, 1% and 2% of lactic acid bacteria are added to the pig's full price feed respectively, C', D' are the control group, A', B', C ' and D' each added 1...

Abstract

The invention discloses a method for reducing skatole in a live pig. By injecting glutamine dipeptide into the vein of the pig, the intestinal permeability of the pig is reduced, the absorption of thepig intestine to skatole is reduced, and skatole is prevented from entering blood and fat through the intestinal wall of the pig. At the same time, by adding isomaltooligosaccharides, lactic acid bacteria and other additives in daily ration, the content and survival rate of lactic acid bacteria in the intestinal tract of the pig are increased, the intestinal digestion ability of the pig is enhanced, the organic acid secretion of the lactic acid bacteria is promoted, the pH value of the pig intestine is reduced, the skatole conversion rate of tryptophan is then reduced, and the skatole generation in the pig intestine is reduced. The skatole content in the live pig is significantly reduced, the quality of pork is improved, the taste of pork is improved, and bad odor is removed.

Description

technical field [0001] The invention belongs to the technical field of livestock breeding and relates to a method for reducing skatole in pigs. Background technique [0002] After the pig eats, the undigested protein in the small intestine is decomposed under the action of anaerobic microorganisms in the large intestine to produce tryptophan, which is further degraded to produce skatole, which is absorbed into the blood circulation system through the intestinal wall, and part of it is metabolized by the liver Excreted by urine, the other part is stored in fat and muscle tissue. High levels of skatole in these tissues can produce an unpleasant smell and taste in pork, affecting the texture and taste of pork. [0003] At present, castration of pigs is widely used in China to reduce the production of skatole in pigs. However, pig castration, as a stress technique, is not conducive to the growth of pigs. However, the method of reducing skatole in pigs by adjusting the composi...
