Quero to clarify Luis Maldonado that the NRC is not a formulation program, this it is the institute that is devoted to establish the requirements nutricinales for the different animal species, obsolete in it paginates it of the NRC ecuantras nutritional requerientos for pigs I finish it it is of the 1998, but won milkman stops and of meat you find those of 2005 2006, the same thing for cats, dogs and fish, formulation programs are Mixit - win3, Mixit-2 brile and other, to formulate at the minimum cost is made by means of the use of a formulation program or the use of a program of lineal programming for that I eat your you say serious to formulate hit or miss, without having encuenta the prices of the matters cousins, a food formulated hit or miss can leave you at the same cost one bought or maybe but expensive.
The step leaves to formulate they are the following ones:
So that species is the food
To establish the nutritional requirements (Already defined we won't invent them)
With which matters cousins prepare and prices put in the property
With the listing of nutritious and the listing of ingredients with their respective prices one runs the formulation, the program it throws me an it formulates that it fills me the nutritional requirement but at minimum cost.
It is necessary to observe here that if I don't have many matters cousins, I am not able to him exiguir to program that I am filled all the nutritional requerimentos of the animal, it should be prioritized, if single story with 4 matters cousins, alone I ask him me to be filled protein, energy, calcium and match, fiber maxino and etc, but if dispngo of synthetic amino acids, mineral vitamin premezclas, sources of protein of animal origin and vegetal,variedad of sources of energia.le can exiguir that mellene most of these.
You can formulate with matters you not prevail conventional, fresh banana, fresh yucca, cane juice, cane picada,lombrices, fly larvas, blood fresca,bore, chachafruto, pejibaye etc. If the formulador has these analyses complete proximales he/she can make it.
