Poultry is a strategic branch of the animal husbandry sector with great possibilities for recovery in a short period of time. Feeding is responsible to the greatest extent for the growth and development of poultries, maintaining their health and achieving the purpose for which they are exploited, namely the achievement of meat production. A balanced diet provides essential nutrients for the development, growth and optimal func-tioning of the avian body. The studies were carried out at the company "Sum Agro Service", on hybrid broilers, raised in batteries ensuring microclimate conditions and with the feeding system according to the breeding guide. Ross 308 cross broiler chickens were used for the experiment. It was es-tablished that the growth of ROSS 308 broiler chicken hybrids raised according to the in-tensive system in accordance with the recommendations and the principles of the breeding guide for meat production is of zootechnical interest and depends on the genetic potential, which it was achieved only under the conditions of proper nutrition and knowledge of the particularities of growth.
