Embodiment 1

[0043] 1 test material

[0044] The amino acid additive is composed of the following components in various mass percentages:

[0045] Threonine 20%; Leucine 25%; Arginine 25%; Isoleucine 20%; Glutamine 10%.

[0046] 2 Experimental Design and Animals

[0047] In this experiment, 20 28-day-old healthy “Du × Chang × Da” three-way hybrid piglets weaned were randomly divided into two groups according to the principle of similar body weight, namely the control group and the additive group:

[0048] Control group:

[0049] Feeding the basal diet shown in Table 1;

[0050] Additive group:

[0051] Feed the following diet: the cornstarch that accounts for 0.5% of the total weight of the diet in the basal diet shown in Table 1 is replaced by the diet obtained after the amino acid additive obtained in the embodiment;

[0052] Each group had 10 replicates, and each replicate had 1 piglet. The test period is 10 days.

Abstract

The invention discloses an amino acid additive capable of improving the growth capacity and intestinal health of a weaned pig. The effective constituents of the amino acid additive include threonine, leucine, arginine, isoleucine and glutamine. By adding 0.5-1.0% of amino acid additive to the basic ration of the piglet, the intestinal structure of the piglet can be improved, synthesis of intestinal mucous protein is promoted, the immunity of the intestinal tract is improved, in this way, the intestinal health of the piglet is improved, the diarrhea rate is the piglet is lowered, and the growth capacity of the piglet is improved.

Description

technical field [0001] The invention relates to an amino acid additive for improving growth performance and intestinal health of weaned piglets. Background technique [0002] In modern pig farming, early weaning of piglets is a technical measure to increase the annual productivity of sows and reduce the spread of diseases in sows and piglets. However, weaning stress leads to early weaning syndrome in piglets, which leads to impaired intestinal barrier function in piglets, manifested as changes in the morphology and structure of the intestinal mucosa, increased permeability of the intestinal epithelial barrier, immunosuppression, and imbalance of intestinal microbial flora etc., which in turn lead to intestinal damage in piglets. Therefore, research on intestinal injury repair and its nutritional regulation has attracted increasing attention. Contents of the invention [0003] The purpose of the present invention is to provide an amino acid additive for improving growth p...
