As poultry industries throughout the world increase in size, the importance of feed production also continues to increase. One of the main objectives of animal nutrition is to formulate diets that allow a predetermined rate of production to be achie- ved at least cost.
The supply of balanced nutrients in animal feed is one of the most critical requirements for achieving optimal growth. Protein, especially, is the major nutrient that determines the performance of animals, assuming that energy is non-limiting. It is also an expensive dietary constituent and
there is much concern about optimizing its dietary concent-
ration in commercial practice.
Dietary protein must be judged as a source of individual amino acids which are needed for synthesis of protein by the animal.
Just as for the other species, genetic progress, physiological stage of animal,, the age of the animal and your personal target has a considerable influence on dietary amino acid concentrations requirements.
Over the last 30 years, production to a constant age has increased by more than 30 %, while feed consumption has been reduced by about 10 %. An important consequence of this genetic progress has been a change in the daily amino acid requirements. It has also called into question the practice of using single feed for laying birds which is practice by some farmers. There are factors that determine the nutrient requirements of a laying birds which inturn form the basic for formulating diet using ROSTAGNO MODELLING EQUATION.
Some factors to consider are:
1). Age of the animal
2). Weight gain of the birds per day.
3). Percentage production
4). Weight of the egg
5). Egg Dough
6). Quantity of feed given to the animal.
Using of a single feed formular might be affecting the laying production over the time. For example, the layers having production of about 85% with 60 gram weight of egg the required nutrient will be different from the ones having 60% production and 45 gram of egg.
Don’t use single formular for the laying birds, always adjust the formula as the production increases.
