Embodiment
The embodiment of the method for distributing rationally of feed formula of the present invention can further specify as follows:
At first measure a kind of animal under the Different Nutrition condition by raising experiment, the feed intake of different days, kind, parity, body weight, butterfat percnetage, temperature, environmental baseline and production performance, with these data as test figure.The data such as feed intake, forage standard, production performance, body weight of collect culturing animal different phase in the handbook in addition are as information data.And with above experimental data and information data establishment formation base data module.
Write a cover multiple regression program module with VB (Visual Basic programming language), and return out the relation curve module of the Different Nutrition composition demand of poultry, domestic animal and temperature, body weight, growth phase, feed intake, production performance with this multiple regression program module according to the data in the basic data module.
Growth phase, environment, body weight, temperature of importing animal then etc. influences the condition of nutritional need, calculates the best nutritional composition demand of poultry, domestic animal under this condition with the relation curve module.
At last make feed formula according to each nutrition demand of the best.
Illustrate as follows:
Age.The nutritional need of animal is a kind of mode of falling growth curve with the variation at age (specifically week age or age in days) to be changed, as shown in Figure 1.So when doing prescription to animal, should carry out according to the difference of animal age.
Body weight.The rate of change of the weight of animals has reflected the speed of weightening finish, and also keeping with the nutrition of animal need be relevant, therefore to a set fowl group, correspondingly design trophic level according to the variation of body weight.Fig. 2 has shown the relation of body weight and nutrient concentration.
Environment temperature.No matter nutrient concentration is high and low, and when variation of ambient temperature, the feed intake of animal can make corresponding changes, as shown in Figure 3.In critical valve, when temperature raise, feed intake can leniently reduce.Outside critical valve, variation of temperature can acutely influence feed intake, therefore in different seasons, correspondingly adjust nutrient concentration according to the variation of environment temperature.
Production performance.Animal under different production status to the nutritional need difference.In daily ration nutrient concentration not simultaneously, the production performance of animal also can make corresponding changes.Fig. 4 has shown the influence of different trophic level to laying hen laying rate and egg size with Fig. 5.It is relevant that nutrient concentration that different is and egg size almost are in line, and nutrient concentration and laying rate are a kind of to positive correlation.
Kind and strain.Fig. 6 has shown two different strains of same kind and but digestible lysine and egg has been added the change curve of cystine requirement.Not only different strain demands are widely different, and the variation pattern of different amino acid requirement amounts is also different.Fig. 7 has shown different cultivars and daily ration crude protein level not simultaneously to the variation of laying rate, the crude protein for 14.4% and 16.8%, and the different cultivars reflection is also different.
Other factor that influences the animal demand still has many, as the energy amino acid ratio, and the interaction between the health status of animal, hormone, enzyme preparation, microbiotic etc. and the nutritional labeling etc.
With influential Animal nutrition demand factor and at the production performance of each factor condition input computing machine, return mathematical model and represent each other relation.For example:
Laying rate and nutrient concentration can be expressed as: laying rate=aLnN-bN-c;
Egg size and nutrient concentration can be expressed as: egg size=a+bN;
Body weight and nutrient concentration can be expressed as: body weight=aLnN-bN-c;
Nutrition and feed intake can be expressed as: feed intake=a-bN
2+ c;
Above-mentioned various in, N is a nutrient concentration, a, b, c are respectively the coefficient of relationship of different production performances and energy concentration or concern constant.
By computer programming, above-mentioned mathematical model is applied to formula software then,, makes the preferred plan that satisfies the Animal nutrition needs by the unify application of mathematical model of department of computer science.
When practical application, the numerical value of all influence factors input computer, calculate nutritional need by computer software, make and satisfy the demand and the minimum prescription of cost.
The application of mathematical model can be satisfied the nutritional need of animal to greatest extent according to situations such as the growth of animal, productions.Also can adjust the production performance of animal by the change of trophic level, find out the optimum of a kind of feed input and the product price differential of selling, promptly obtain the equilibrium point of maximum economic benefit.When animal product price and feed price change, can by reduce or the concentration that has additional nutrients (promptly changing the input of feed) thus reduce or improve the purpose that product yield reaches maximum economic benefit.
