This paper shows a bio-economic analysis model in Tetra H hybrid, raised in organic system, in line with the protein intake and of the body weight registered during the experimental period. The mathematic model y=a/(l+bx+cx2) allows the assessment of the expenses recorded with chicken feeding depending on crude protein intake. The model also validates the possibility to simplify the chickens' nutrition technology (starting from a triphase fodder feeding to a diphase fodder feeding) and at nutritional (protein) levels adapted to the desired body weight. The indices of correlation between the expenses registered with fodder feeding and crude protein intake show us that between them there is a strongly positive correlation, thus: 0.958 (in Tl), 0.980 (in T2) and 0.972 (in T3). The indices of determination (R2) corresponding to the three experimental variants are higher, with values over 0.963, and the error percentage of the mathematical model is reduced (below 6%). Based on the results obtained in Tetra H chickens, it may be recommended a diphase fodder feeding (with starter fodder between 1-21 days and grower-finisher fodder between 22-112 days) with concentrates mixtures (CM) by 22% and 17,5% CP and 2971 and 3160 kcal ME/kg.
