Method for evaluating effective energy value of yellow-feathered broilers fast by utilizing chemical constituents of soybean meal

Abstract

The invention relates to a method for evaluating the effective energy value of yellow-feathered broilers fast by utilizing chemical constituents of soybean meal. The method comprises the following steps: testing the basic crude protein content CP of dry matters in the soybean meal, the basic crude fiber content CF of the dry matters; substituting CP values and CF values into a constructed mathematical model, so as to obtain the basic apparent metabolic energy of the dry matters in the soybean meal. The method is fast, dynamic and accurate; during feed formulation, the apparent metabolic energy value of each chemical constituent of the soybean meal can be calculated fast and dynamically; the method can be used for feed formulation of the yellow-feathered broilers directly; the apparent metabolic energy value obtained according to the method can be more accurate than the fixed apparent metabolic energy value of white-feathered broilers to the soybean meal in a database.

Description

technical field [0001] The invention belongs to the field of poultry feed, in particular to a method for quickly evaluating the effective energy value of yellow-feathered broiler chickens by using the chemical components of soybean meal. Background technique [0002] Soybean meal is the most commonly used protein source feed material in poultry farming. Its crude protein content, crude fiber, etc. have large differences due to different production processes, so there are large differences in its metabolizable energy value for broilers. [0003] At present, poultry feed basically adopts apparent metabolizable energy for feed preparation. Yellow-feathered broilers account for about half of the broiler chickens in my country, and there are very few studies on the apparent metabolic energy of yellow-feathered broilers to soybean meal. Accurate determination of apparent metabolizable energy of soybean meal is very important for formulating appropriate feed for yellow-feathered b...

Problems solved by technology

[0004] Therefore, the disadvantages of the method of measuring the apparent metabolizable energy of soybean meal by poultry by metabolic test include: ①The time required for the measurement is relatively long, generally about 20 weeks from the start of chick feeding, which is time-consuming and laborious

②Because it takes a long time to measure the apparent metabolizable energy of soybean meal, the results are difficult to use in the feed production of yellow-feathered broiler chickens. At the same time, there are few studies on the apparent metabolizable energy of soybean meal for yellow-feathered broiler chickens. Fixed value of apparent metabolizable energy value for soybean meal in white feather broiler chicken in database table

The main reasons for the above are: At present, there are few data on the determination of the apparent metabolizable energy of yellow-feathered broilers to soybean meal, and a reliable method for quickly and dynamically evaluating the apparent metabolizable energy of yellow-feathered broilers to soybean meal has not yet been established.
