Feeding method for dynamic supply of protein and amino acids in goose diets

Abstract

The invention relates to a feeding method for dynamic supply of protein and amino acid in goose diets. In every morning and night, the fodder comprises crude protein 12.8-14.4%, lysine 0.68-0.77%, methionine 0.36-0.41%, threonine 0.48-0.54%, tryptophan 0.20-0.23% and arginine 0.80-0.90%, the fodder at noon comprises crude protein 16%, lysine 0.85%, methionine 0.45%, threonine 0.60%, tryptophan 0.25% and arginine 1%, and the method adopts free food intake. This method reduces protein intake, does not affect the slaughter performance of geese, and reduces nitrogen emissions.

Description

technical field [0001] The invention belongs to the technical field of vertebrate breeding, and in particular relates to a feeding method for dynamic supply of goose dietary protein and amino acids. Background technique [0002] Studies have shown that there are differences in the metabolism and demands of animals at different time points. The physiological activities of the animal body in terms of digestion and metabolism of nutrients have a certain periodicity, which changes with the alternation of day and night, showing an inherent circadian rhythm phenomenon. At the same time, under the regulation of the biological clock, nutrients also affect the rhythmic metabolic activities of the body. Due to the lack of understanding of the real-time dynamic changes of the nutritional needs of livestock and poultry, as well as the accurate assessment of the real-time dynamic changes of feed raw materials nitrogen (amino acids) and carbohydrate titers and their requirements, for a l...

AI Technical Summary

Problems solved by technology

Appropriate protein levels in feed can promote the growth of livestock and poultry, while excessive protein levels will cause excess protein to be discharged into the environment in the form of nitrogen, which not only increases the cost of feeding, but also causes pollution to the environment
