Problems solved by technology

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 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 and D are the experimental groups, and 0.5%, 1% and 1.5% of edible activated carbon are added to the pig's full-price feed respectively, and the E group is 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] Pigs were slaughtered when their weight reached 100kg, and the pork back fat was taken to detect the content of 3-methylindole (skatole). The results are shown in Table 1.

Embodiment 2

[0027] 120 castrated boars with a body weight of 60.0±1kg were divided into 6 groups A, B, C, D, E and F, with 4 replicates (pens) in each group and 5 pigs in each replicate, wherein A, B, C, and D are the experimental groups. Add 0.5g, 1g, 1.5g, and 2g of glutamine per kilogram to the full-price feed of pigs, and add 1.5% edible activated carbon to the groups A, B, C, D, and E. . Group F is 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.

Abstract

The invention discloses a feed additive for reducing scatol in bodies of live pigs and a preparation method of the feed additive. The method comprises the following steps of adding additives of glutamine, edible activated carbon, sodium humate and the like to a ratio of the pigs, wherein the glutamine can reduce the mucosa permeability of pig intestines, can reduce the absorption of the pig intestines to scatol, and can effectively prevent the scatol from entering blood and fat through the walls of the pig intestines. Besides, through absorption function of edible activated carbon, scatol generated in the pig intestines can be adsorbed, and the scatol is discharged outside the pigs along with excrement and urine; and after the sodium humate enters the pig intestines, residual humic acid molecules can absorb ammonia in the excrement and urine, and the malodour of the excrement and urine is reduced. The feed additive is added to the ration of the pigs, under the premise that sufficient nutrient absorption of the live pigs can be guaranteed, the content of the scatol in the bodies of the live pigs is notably reduced, the pork quality is improved, the mouth feel of the pork is improved, and bad smell is removed.

Description

technical field [0001] The invention belongs to the technical field of livestock breeding, and relates to a feed additive for reducing skatole in pigs and a preparation method thereof. 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...
