Embodiment 1

[0018] A feed additive for regulating intestinal physiology of piglets, the main components are 350 parts of calcium sulfate dihydrate, 40 parts of plant extract preparations, 10 parts of glutamic acid, 20 parts of aspartic acid, 30 parts of L-lysine, and 50 parts of carrier share. A total of 72 21-day-old piglets with good body condition and similar body weight were selected and divided into 2 treatments, each treatment had 6 replicates, and each replicate had 6 piglets. The control group was fed the basal ration, and the basal ration of the test group was added with 0.1% of the piglet feed additive of the present invention. Feeding management and immunization procedures were carried out in accordance with routine, and the test period was 14 days. The test results are as follows:

Embodiment 2

[0024] A feed additive for regulating the intestinal physiology of piglets. After mixing 40 parts of plant extract preparations with 40 parts of carriers, they are evenly stirred with 20 parts of glutamic acid, 20 parts of aspartic acid and 40 parts of L-lysine, and then It is prepared by thoroughly mixing with 300 parts of calcium sulfate dihydrate and 40 parts of carrier. The test selected 72 “Du×Chang×Da” three-way hybrid piglets weaned at about 28 days of age, and randomly divided them into 4 treatments according to the principle of similarity in weight, sex and genetic basis. Each treatment had 3 pens, and each treatment had 6 piglets. (3 males and 3 females). Add 0%, 0.05%, 0.10%, and 0.20% feed additives for intestinal physiology of piglets in the basal diets of the four treatments, respectively. The test pigs were raised in high beds, free to eat and drink, and the immunization and disinfection procedures were carried out according to the routine of the pig farm. The ...

Embodiment 3

[0030] Example 3 Weigh a certain weight of full-price compound rations for weaned piglets, and then weigh feed additives that regulate the intestinal physiology of piglets according to the weight ratio, and add them to the full-price compound rations for weaned piglets according to the ratio of 0.05% WT%. , fed directly or made into pellet feed after fully stirring evenly.

Abstract

The present invention discloses a piglet intestinal physiology regulating feed additive added into piglet daily diet and a use method thereof. The feed additive includes the following main ingredients: 300-370 parts of calcium sulfate dihydrate, 20-40 parts of plant extracts, 10-20 parts of glutamic acid, 10-20 parts of aspartic acid, 20-30 parts of L-lysine and 40-100 parts of a carrier. The provided feed additive is mainly used in the weaned piglet daily diet at a ratio of 0.05-0.5 wt%. A feeding experiment proves that the additive can improve the granulation effect of a feed, and has very significant effects in regulating the intestinal pH value of the piglets, improving the absorption efficiencies of the piglets for calcium and other nutrients in daily diet, and promoting the growth of the piglets. The features of the invention are as follows: the feed additive can regulate intestinal acid-base balance, promote intestinal tract absorptions of the calcium and other nutrients, reduce diarrhea incidence, and promote animal growth, and is a safe, non-toxic, free of side effects, free of drug residues, and green feed additive.

Description

technical field [0001] The invention relates to a feed additive for regulating intestinal physiology of piglets, and belongs to the technical field of feed additives. Background technique [0002] Piglet health is the key to pig production, and intestinal health is the core of piglet growth and development and the basis for rapid growth. Especially when piglets are weaned, piglets will face a lot of physiological stress such as dietary changes, separation of mother and piglets, environmental changes, etc., which will lead to histological and physiological changes in the intestines of piglets, causing indigestion and decreased absorption function of piglets, and even The immune function is reduced, resulting in diarrhea, growth retardation, etc., and reducing the performance of piglets. Therefore, adjusting the intestinal acid-base balance of piglets and maintaining intestinal health is the key to ensuring the growth of piglets, which is of great significance to the entire p...
