Abstract

The invention discloses a compound premix for promoting the calcification of meat duck breastbone. The compound premix comprises the following constituents in parts by weight: 10-30 parts of bacilluslicheniformis, 5-15 parts of sodium borate, 15-30 parts of magnesium oxide, 5-15 parts of beta-cyclodextrin, 5-15 parts of protease, 5-15 parts of sodium butyrate and 15-30 parts of raw potato starch.The compound premix is added and used in fodder for meat ducks of 15-49 days old. 0.05% of the compound premix disclosed by the invention is added into the fodder for the meat ducks, the calcification of the meat duck breastbone can be remarkably promoted, the production performance of the meat ducks is improved, and the product quality of slaughtered meat ducks is increased.

Description

technical field [0001] The invention belongs to the technical field of poultry feeding, and in particular relates to a compound premix for promoting breastbone calcification of meat ducks. Background technique [0002] Breast muscle weight and breast muscle ratio are important economic traits in broiler poultry production. There is a relationship between the development of the pectoral muscle and the development of the sternum in birds, which is not only reflected in the attachment of the pectoral muscle to the sternum and the support of the sternum to the pectoral muscle, but also in the phenotypic and genetic positive correlation between the weight of the pectoral muscle and the length of the keel. Studies have shown that the process of bone calcification is the basis for bone maturation and morphogenesis. The sternum not only provides the fulcrum for the attachment of the pectoral muscles, but also affects the respiration of the bird by affecting the contraction of the a...
