Embodiment Construction

[0008] The first step is to prepare the nutritional target value

[0009] You can directly use the indicators recommended by the feeding standards or nutritional needs. It is best to use the feeding standards or nutritional needs as the basis, and summarize a set of target values ​​for your own nutritional needs in production practice. The type and quantity of nutritional target values ​​can be determined according to one's own needs, and the target value should not be too little or too much. Under normal circumstances, it should include exergy value, crude protein, calcium, phosphorus and the first and second limiting amino acids.

[0010] The second step is to prepare raw material data

[0011] Organize and summarize the nutritional indicators of various feed ingredients to be used in the formula. The type of nutritional index of each raw material should be the same as that in the nutritional target value. The nutritional index data of feed raw materials should be as clos...

Abstract

The invention relates to a method for designing a feed formula based on a trial and error process, and belongs to the feed industry. The trial and error process is a practical feed formula process, so the trial and error process is easy to learn for people who have not learned the feed formula and is not limited by the type of feed raw materials and the number of nutritional indexes. Under the condition of manual calculation, in case of many types of the feed raw materials and more nutritional indexes taken into consideration, the design of the feed formula is time-consuming and laborious. However, under the condition of the ready-made computer operating module, the practical feed formula with low cost and ideal effect can be obtained within a short time so long as to understand the main characteristics of the feed raw materials and utilize the feeding standard reasonably. In a goldpoint feed formula, a formula checking module is ready-made, and can be used directly.

Description

technical field [0001] The invention relates to a trial and error feed formulation design method, which belongs to the feed industry. Background technique [0002] At present, the design methods of feed formula mainly include: diagonal method, trial and error method, computer multiple regression and linear programming method. [0003] Diagonal method is a traditional feed formula design method, which is suitable for simple formula design of 4 to 5 raw materials, but it cannot meet the needs of formula checking and calculation, and few people use it now. [0004] The computer multiple regression and linear programming methods use the computer as the working platform and use its powerful computing functions to check the formula, and can calculate the feed formula with the most complete nutrition and the lowest price. The disadvantage is that the formula lacks flexibility, and the designed formula has no characteristics. [0005] The trial and error method is a practical feed...
