Abstract

The invention provides a method for improving poultry production efficiency by rapidly evaluating liver weight and liver-to-body ratio, which comprises the following steps: (1) acquiring total cholesterol content in blood of a plurality of poultry in a preset poultry species group, and weighing the weight and liver weight of the plurality of poultry in the preset poultry species group through a balance; (2) respectively carrying out curve fitting on the obtained total cholesterol content, the liver weight and the liver-to-body ratio, and establishing a regression equation; (3) obtaining the total cholesterol content of the blood of the poultry to be detected in the preset poultry species group; and (4) obtaining the liver weight and the liver-to-body ratio of the poultry to be detected according to the regression method.

Description

technical field

[0001] The invention relates to the technical field of poultry breeding, in particular to a method for improving poultry production efficiency by rapidly evaluating liver weight and liver-to-body ratio. Background technique

[0002] Animal liver has the functions of secreting bile, storing glycogen, regulating the metabolism of protein, fat and carbohydrate, as well as detoxification, hematopoiesis and coagulation. Since 95%-98% of poultry's lipid synthesis comes from the liver, the health of the poultry liver is even more important to maintain the body's functions. Under the intensive breeding mode, the liver of poultry will cause subclinical damage due to factors such as recessive infectious diseases, environmental stress, and the replacement of feeding processes, showing symptoms such as swelling, congestion, hemorrhage, fatty degeneration, and amyloidosis. Compared with the normal production state, there are no clear and perceptible clinical symptoms, bu...
