Abstract

The invention discloses a growth promoting agent for promoting the growth of a weaned pig and an application. The growth promoting agent consists of N-acetyl-L-cysteine and acetaminophen at a certain ratio, and is prepared according to the following steps: step A, proportionally weighing the N-acetyl-L-cysteine; step B, proportionally weighing the acetaminophen; step C, sequentially adding the weighed N-acetyl-L-cysteine and acetaminophen into a mixer and fully mixing to obtain the growth promoting agent applicable to the weaned pig. The invention also discloses the application of the growth promoting agent for the weaned pig to feeds for the weaned pig. The feed additive can be used for relieving weaning stress of the pig, increasing the average daily gain of the weaned pig by more than 230%, reducing the feed to gain ratio by more than 40%, reducing the incidence of diarrhea by more than 54% and remarkably improving the growth performance of the pig, causes no resistance to drugs, can be used for effectively replacing an antibiotic growth promoting agent and satisfies a healthy breeding development direction.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry or feed, and more specifically relates to a growth-promoting agent for weaned piglets, and also relates to an application of the growth-promoting agent for weaned piglets in weaned piglets. Background technique [0002] In the modern pig industry, early weaning of piglets has been widely promoted and applied due to its advantages of improving the production efficiency of sows, promoting early growth of piglets, and reducing feeding costs. However, early weaning stress in piglets can cause gastrointestinal dysfunction in piglets, induce early weaning syndrome in piglets, lead to slow growth or stagnation, and even death of piglets, which has brought huge negative effects on piglet growth and pig production. Modern studies have shown that the nutrition of piglets at weaning stage is the main aspect affecting weaning stress, and the nutritional components, raw material composition, grain siz...
