Problems solved by technology

[0003] Nowadays, the evaluation of the metabolizable energy of goose oil in my country is facing two major technical problems: one is that oil is a high-energy feed, and it cannot be fed alone to determine its metabolizable energy value on geese; the other is that when measuring the metabolizable energy of lipid feed, often The measured metabolizable energy values ​​fluctuate due to differences in replacement ratios, methods used, and basal diets or carriers
[0004] At present, the research on the determination method of goose's lipid metabolism energy is still blank at home and abroad. Therefore, it is the basis to obtain the accurate metabolism energy value of goose oil and establish a standard measurement method.

Abstract

The invention relates to a method for determining a metabolic energy value of a goose on grease, namely, adding 10% of grease and 1% of microelements and vitamins to the basic ration of the goose to replace the basic ration to be fed so as to accurately determine the metabolic energy value of the goose on the grease. According to the method disclosed by the invention, 10% of grease is added to the basic ration to be fed to the goose so that the metabolic energy value is determined, thus the determined metabolic energy value of the grease is closer to the metabolic energy value under conventional daily ration feeding conditions, and difficulty on stress and excrete collection caused by single feeding is avoided. Through feeding the goose with nitrogen free diet to collect endogenous excreta, the energy value of endogenous excreta can be measured, the real metabolic energy value can be corrected, and a real metabolic energy value can be determined exactly. During the determination of the metabolic energy value of the goose on the grease, the metabolic energy value can be increased by adding quantitative microelements and vitamins, a variation coefficient of determined data is reduced, and the stability of the determination value is improved.

Description

technical field [0001] The invention belongs to the technical field of breeding poultry metabolism research, and in particular relates to a method for measuring the metabolic energy value of goose to oil. Background technique [0002] At present, the annual feeding capacity of meat geese in my country has reached 1 billion, and the utilization of oil in goose feed is gradually increasing. There are many reports on the metabolizable energy value and determination methods of chicken and duck fat at home and abroad, and relevant feeding standards have been formulated. However, there are few studies on the metabolizable energy value of geese, and some reported measurement methods and data are quite different, which cannot be used as the basis for formulating geese feeding standards and guiding ration formulation in feed production. Therefore, it is of great significance to determine the determination method of lipid metabolizable energy of goose to standardize the determination...
