Applications of leucine in promotion of milk secretion and growth aspects of breeding pigeons

Abstract

The invention discloses applications of leucine in promotion of milk secretion, reproductive performance, and growth and slaughter performance aspects of breeding pigeons. Research found that by adding certain leucine in basic ration, the pigeon's milk protein synthesis can be regulated (reflected by young pigeon weight gain), the incubation period weight of the breeding pigeon can be increased, and the whole-phase weight loss can be reduced; the thickness and relative weight of crop of the breeding pigeon can be increased; the growth performance and slaughtering performance of the young pigeon can be improved, and the mortality rate of the young pigeon can be reduced. Therefore, the leucine has good applications on the aspects of feed additives of the breeding pigeons, especially the growth performance and slaughtering performance of the young pigeon.

Description

technical field [0001] The invention belongs to the technical field of breeding. More specifically, it relates to the application of leucine in promoting the milk secretion of breeding pigeons and the growth of pigeons, specifically in improving the reproductive performance of breeding pigeons, the production performance and slaughter performance of pigeons, and as a feed additive for breeding pigeons. Background technique [0002] With the improvement of residents' quality of life and consumption level, meat pigeons have become the fourth largest category of meat poultry after chickens, ducks and geese. Especially squab, the pigeon meat is delicious, tender and rich in nutrients such as crude protein and a small amount of inorganic salts. It has a strong nourishing effect and is a rare food delicacy. In recent years, the scale of its industry has developed rapidly, and meat pigeon breeding is gradually changing from free-range farming to large-scale farming. However, becau...

Problems solved by technology

In recent years, its industrial scale has developed rapidly, and meat pigeon breeding is gradually changing from free-range farming to large-scale farming. However, because the industry is still in its infancy and basic research is lacking, it has become a bottleneck restricting the development of the industry.
