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
The present invention is a kind of method of try and error method feed formula design, belongs to feedstuff industry.
Background technology
At present, the method for designing of feed formula mainly contains: diagonal method, try and error method and computer multiple regression and linear programming technique.
Diagonal method is a kind of traditional feed formula method for designing, is applicable to the simple formulation design of 4～5 kinds of raw materials, can't be suitable for prescription checking computations needs, and few people use at present.
It is workbench that computer multiple regression and linear programming technique are to use computer, utilizes the checking computations of filling a prescription of its strong calculation function, can calculate the feed formula that nutrition is the most complete relatively, price is minimum relatively.Shortcoming is that prescription lacks flexibility, and the prescription that designs does not have characteristics.
Try and error method is a kind of feed formula method of practicality, is easy to study for the personnel that do not learn feed formula, and does not receive the restriction of feedstuff kind and nutritive index quantity.Under the situation of hand computation, nutritive index many like the feedstuff kind, that consider is many, and then designing feed formula can waste time and energy very much.Under the situation that ready-made computer computing module is arranged,, just can make practicality, cheapness, feed formula satisfactory for result at short notice as long as understand the feedstuff key property and rationally utilize feeding standard.The gold point feed formula has ready-made prescription checking computations module, can directly use.
Summary of the invention
Originally sentence try and error method and be example and tell about the compound method of laying hen peak material (lay eggs >=80%).
Use corn, dregs of beans, fish meal, cotton dregs, the certain herbaceous plants with big flowers dregs of rice, the dish dregs of rice, stone flour, calcium monohydrogen phosphate, salt, lysine, methionine, vitamin premix, layer chicken feed prescription of microelement pre-mix material design.
The specific embodiment
The first step is ready to the nutritional goals value
The index that can directly use feeding standard or nutritional need to recommend preferably is the basis with feeding standard or nutritional need, in production practices, sums up the nutritional need desired value of a cover oneself.Nutritional goals value kind and quantity can confirm according to the demand of oneself, and desired value can not be very little, can not be too many.To include efficiency value, crude protein, calcium, phosphorus and first, second limiting amino acid under the normal condition.
Second step was prepared the raw material data
Put the nutritive index of all feeds raw material that will use in the prescription, conclude in order.The nutritive index kind of every kind of raw material will with the nutritional goals value in identical.Each item nutritive index data of feedstuff will be as far as possible near actual content; Can be through selecting the feedstuff nutritive index data of local raw material data or authoritative institution issue for use, also can be through actual detected or the nutritive index data of consulting producer and providing make the raw material nutritive index more accurate.Generally directly select for use the data in " Chinese feed ingredient and nutritive value table " to get final product in China.
The 3rd step was calculated nutritive index
According to the proportioning raw materials of first plan prescription, calculate the nutrient concentration of every kind of nutrient in daily ration in the prescription respectively.Method: calculate certain nutrient content * proportioning raw materials of every kind of raw material, both got the concentration of certain nutrient in daily ration to the calculated value addition of every kind of raw material then.By all calculating the nutrient index of all kinds with quadrat method.
Crude protein: corn 8.2 * 60%+ fish meal 62.80 * 5%+ ... + methionine 58.6 * 0%=17.3%
Metabolizable energy: corn 3.28 * 60%+ fish meal 2.79 * 5%+ ... + methionine 5.02 * 0%=2.76%
Lysine: corn 0.29 * 60%+ fish meal 2.42 * 5%+ ... + methionine 0 * 0%=0.85%
The prescription adjustment of the 4th step
The nutritional goals value contrast that each item nutritive index and the first step are provided with, not enough like metabolizable energy, increase the corn ratio; Like protein deficient, increase fish meal, dregs of beans ratio; Hypocalcia increases the stone flour ratio; Phosphorus is not enough, increases the calcium monohydrogen phosphate ratio.Repeat the calculating in the 4th step then.Through the gap of result of calculation and nutritional goals value relatively, adjust proportioning raw materials repeatedly, up to except that lysine, egg+Guang, other index all meets till the nutritional need.
Claims (2)
1. the present invention is a kind of method of try and error method feed formula design, is characterised in that its prescription.
2. according to the method for right 1 described a kind of try and error method feed formula design, its prescription is: crude protein: corn 8.2 * 60%+ fish meal 62.80 * 5%+ ... + methionine 58.6 * 0%=17.3%
Metabolizable energy: corn 3.28 * 60%+ fish meal 2.79 * 5%+ ... + methionine 5.02 * 0%=2.76%
Lysine: corn 0.29 * 60%+ fish meal 2.42 * 5%+ ... + methionine 0 * 0%=0.85%.
