Problems solved by technology

At present, a large number of domestic researches mainly focus on the nutritional physiological effects of amino acids in low-protein diets and the nutritional metabolism of diets with different protein levels under the ideal protein amino acid model, while ignoring the nutritional and metabolic effects of feed protein itself.

Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with specific embodiments.

[0011] Select 36 healthy 21±1d weaned DLY (Duroc×Landrace×Yorkshire) piglets (average body weight 6.14±0.50kg), adopt a single factor complete experimental design, according to the principle of equal body weight, half male and female, randomly distribute the test pigs Up to 6 treatments, each with 1 replicate, 1 replicate with 1 pig. The treatment groups are: casein source group, soybean protein source group, grain protein source group, soybean protein: corn protein: animal protein weight ratio group is 7:3:1. This experiment was carried out in the experimental field of Animal Nutrition Research Institute of Sichuan Agricultural University, and the feeding and management were carried out according to the conventional feeding and management of weaned piglets.

[0012] result:

Abstract

The invention discloses a dietary protein source combination capable of improving intestinal health of a piglet, wherein the weight ratio of soy protein, cereal protein and animal protein is 7:3:1. The weight ratio of soy protein, cereal protein and animal protein weight ratio is 7:3:1, the protein source can significantly improve the production performance of weaned pigs, improve metabolism, improve the level of piglet body synthetic hormone insulin, has certain effect on the jejunal mucosal nutrient digestive enzyme activity of the weaned pig so as to maintain the normal level and function of the piglet. The dietary protein source combination in which the weight ratio of soy protein, cereal protein and animal protein is 7:3:1 can be used as daily ration protein source, can be more beneficial to the intestinal health of the weaned piglet and facilitates the development of piglet production performance.

Description

technical field [0001] The invention relates to a dietary protein source combination capable of improving intestinal health of piglets. Background technique [0002] For a long time, protein (amino acid) nutrition has been one of the focuses and hot spots in the field of human and animal nutrition research. In aquaculture production, one of the results of the application of ideal protein (IP) theory is to prepare low-protein rations by adding synthetic amino acids, which not only saves the cost of animal protein feed, but also reduces the pollution of the environment by excreting nitrogen. This practical advantage is in today’s The society that advocates energy conservation and emission reduction is particularly prominent. At present, a large number of researches in China mainly focus on the nutritional and physiological functions of amino acids in low-protein diets and the nutritional metabolism of diets with different protein levels under the ideal protein amino acid mode...
