Embodiment 1

[0018] A total of 100 piglets weaned at the age of 21±1 days, Du×long×big piglets were selected and randomly divided into two treatment groups (control group and test group) according to the principle of similar body weight. There were 5 replicates (pens) for each treatment, and 10 piglets per pen. The control group was fed a corn-soybean meal-based diet, and the experimental group was fed a corn-soybean meal-based diet with the addition of 0.3% lactic acid butyrate of the total weight of the feed. After feeding for 28 days, the growth performance, intestinal mucosal morphology, and intestinal tract of weaned piglets were measured. Digestive pH and colonic microbial populations. The results are shown in Table 1, Table 2 and Table 3.

Embodiment 2

[0031] 200 1-day-old Cobb broilers were selected and randomly divided into two treatment groups (control group and test group) according to the principle of similar body weight. There were 5 replicates (columns) for each treatment, and 10 rats in each column (half male and half male). The control group was fed a corn-soybean meal-based diet, and the test group was fed a corn-soybean meal-based diet with the addition of 0.05% lactic acid butyric acid glyceride in the total weight of the feed. After feeding for 42 days, the growth performance, intestinal morphology and structure of the broiler chickens were measured microbial population. The results are shown in Table 4, Table 5 and Table 6.

Embodiment 3

[0042] 240 heterogeneous gibel crucian carp with a body weight of 5.35±0.02 g were selected, randomly distributed in 8 aquariums, and divided into 2 treatment groups, and different gradient levels of glyceryl lactate (0%, 0.1% ), 4 replicates per group, 30 fish per replicate. The 8-week growth test was used to evaluate the effect of glyceryl lactate on the growth performance of the heterogeneous gibel carp. The results are shown in Table 7.

[0043] Table 7 Growth performance of heterogeneous gibel carp during the test period

[0044]

[0045] The data in Table 7 show that adding 0.1% glyceryl lactate to the diet of heterogeneous gibel carp can increase the relative weight gain rate by 10.97% and the specific growth rate by 11.68% (P<0.05), and reduce the feed coefficient by 3.40% (P<0.05 ), which promoted the growth of heterogeneous gibel carp.

Abstract

The invention relates to application of butyrin lactate as a feed additive. The butyrin lactate conforms to the characteristics that the molecular formula is C13H22O8 and the molecular weight is 306.31. The application objects of the butyrin lactate as a feed additive include monogastric animals such as pigs, poultry and the like, ruminants such as cows, sheep and the like, herbivores such as horses, rabbits and the like and aquatic animals such as fishes, shrimps, crabs and the like. The application method comprises the following steps of: directly adding 0.05-0.5% of butyrin lactate into feed based on the total weight of the feed; or mixing the butyrin lactate with an adsorbent to obtain a premix; or mixing the butyrin lactate with other feed additives or feed raw materials to obtain a premix, a concentrate and the like to feed monogastric animals such as pigs, poultry and the like, ruminants such as cows, sheep and the like, herbivores such as horses, rabbits and the like and aquatic animals such as fishes, shrimps, crabs and the like. Through the invention, the butyrin lactate can be slowly decomposed in the gastrointestinal tracts of animals while releasing the characteristics of lactic acid and butyric acid, the pH value of the intestinal tract can be reduced, the intestinal microecology is improved, the growth of the intestinal mucosa can be promoted, the intestinal morphology is improved, and an effect of promoting the intestinal health of animals is realized so as to reduce diarrhea and improve the production performance of animals.

Description

technical field [0001] The present invention relates to the use of glyceryl lactate, in particular to the use in the field of animal feed additives. Background technique [0002] Under natural conditions, lactic acid and butyric acid in the digestive tract of animals are mainly produced by anaerobic fermentation of carbohydrates such as lactose and non-starch polysaccharides in the feed, which not only provide energy for the hindgut mucosa, but also inhibit Harmful bacteria such as Escherichia coli and Salmonella in the intestinal tract promote the growth of beneficial bacteria such as lactic acid bacteria and bifidobacteria. [0003] Lactic acid is often directly used as a feed acidifier. Lactic acid is a feed additive allowed by the state, and its main purpose is acidification. However, after lactic acid enters the digestive tract, it is mainly absorbed in the front part of the digestive tract, especially in the stomach, so it is difficult to play a role in the rear part ...
