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

The method of trial and error in feed formulation

FIELD

[0001] The present invention is a method of trial and error feed formulation, is a feed industry. Background technique

[0002] Currently, the design of feed formulation are: Diagonal, trial and error and a computer multiple regression and linear programming.

[0003] Diagonal is a traditional feed formulation method, the simple recipe designed for 4 to 5 kinds of raw materials, has been unable to apply formula needs checking, has been rarely used.

[0004] Computer multiple regression and linear programming method is to use the computer as a working platform, using its powerful computing capabilities recipe checking, we can calculate the relative nutrition of the whole, the price is relatively low feed formula. The disadvantage is the lack of flexibility formula, no recipe designed features.

[0005] The trial and error method is a practical method to feed formula, for people not studied feed formulation is easy to learn, and is not the type and amount of feed ingredients limiting nutrient indicators. In the case of manual calculation, such as the type of feed ingredients and more, consider more nutrition indicators, the design of the feed formula will be very time consuming. In the case of existing computer algorithms module case, and the main characteristics of the feed ingredients to understand the rational use of standard breeding, it can be formulated in a practical, inexpensive, feed formulation desired results in a short time. Gold feed formulation has a good recipe checking module can be used directly.

SUMMARY

Preparation method [0006] This Example describes impose a trial and error method peak material layers (egg> 80%).

[0007] The use of corn, soybean meal, fish meal, cottonseed meal, sunflower meal, rapeseed meal, powder, calcium hydrogen phosphate, sodium chloride, lysine, methionine, vitamin premix, design a trace element premix feed hens formula.

Detailed ways

[0008] The first step in preparing good nutrition target

[0009] can be used directly or nutritional needs feeding standards recommended indicators, it is best to raise standards or nutritional needs, we summarize a set of their own nutritional needs in production practice target. Nutrition target types and quantities according to their needs to determine the target value is not too little, not too much. To include exergy value under normal circumstances, crude protein, calcium, phosphorus and first and second limiting amino acid.

[0010] Step 2 Preparing the raw data

[0011] The nutritional parameters of various feed ingredients in the formulation to be used has summarized well. The kind of nutritional indicators of each ingredient and nutrition to the same target in. Nutrition indicators data nutrition indicators data feed ingredients should be kept as close to the actual content, by selection of raw materials nutrition indicators data feed raw data or local authority issued, may also be provided by the actual testing or inspection of factory raw material more nutrition indicators accurate. In general direct selection of data to "Chinese feed ingredients and nutritional value table" in.

[0012] The third step is to calculate nutrition indicators

[0013] The proposed formulation ratio of raw materials First, calculate the concentration of the formulation of each nutrient in the diet of nutrients. Method: calculated for each of a nutrient content of the feed raw material ratio X, and the calculated value of each ingredient is added in a concentration of certain nutrients acquired diets. In the same way to all kinds of nutrients indicators are all calculated.

[0014] Crude protein: corn meal 8. 2X60% + 62. 80X5% + ......... + methionine 58. 6X0% = 17. 3%

[0015] ME: corn meal 3. 28X60% + 2. 79X5% + ......... + methionine 5. 02X0% = 2. 76%

[0016] Lysine: corn meal 0. 29X60% + 2. 42X5% + ......... + methionine 0X0% = 0. 85%

[0017] The fourth step formula adjustment

[0018] Comparative Nutrition target nutrition indicators provided with the first step, such as metabolic energy is less, increase the proportion of corn; proteins such as insufficient increase fish meal, soybean meal ratio; I Hack insufficient, increasing the proportion of powder; phosphorus deficiency, increased phosphorylation calcium hydrogen ratio. A fourth calculation step is then repeated. By comparing the calculated results with the nutrition gap target value, adjusting the ratio of raw materials repeatedly, until other than lysine, egg + cystatin, other indicators are in line with the nutritional needs so far.
