Improving the efficiency of the sheep industry is based not only on additional investments, but also on the use of modern methods of breeding and selection. A significant role is given to modeling and forecasting processes in sheep breeding. The article is devoted to the development of a model for the growth and development of lambs in the first months of their post-embryonic period, which contains a system of equations describing the energy, protein and nutritional needs of animals. This model takes into account the influence of environmental factors on the growth and development of lambs and the features of the formation of future productivity.

Keywords: energy and protein requirements, growth and development, modeling, lamb, sheep
