The demographic explosion recorded worldwide in the last century and also the increasing level of living had as result the constantly increasing of the meat requirements.The researches were made in a company from the city of Vaslui, on two groups of half-breed lambs obtained from the crossing of females of Merinos de Palas with males of Ile de France.At the first group the supplementary feeding started when the lambs were 10 days old, when in their food it was provided, in specially arranged places, high quality hayand concentrated forage made in the farm, containing 50 % corn, 40 % oat and 10 % pea, ad libitum.The second group was fed supplementary starting at the age of 10 days, when the lams food was provided, in specially arranged places, high quality hay and compound grain forage for lambs given on discretion. In the period of 10-40 days in the lambs food it was administrated compound grain forage “starter” which provides a level of the protein of 16 % and a minimum level of phosphorus of 0, 45 % and in the period of 40-60 days it was administrated in the lambs food compound grain forage “grower” which provides a level of the protein of 15,8 % and a minimum level of phosphorus of 0,40 %. At the age of 30 days as well at the age of 60 days the lambs from the second group had accomplished body weights higher than the lambs from the first group. The average gain in weight made by the lambs in the second group was higher than the average gain in weight of the lambs in the first group. The lambs in the second group had record in the first 30 days of life average gain of 362 g/day while the lambs in the first group recorded a average gain of 224 g/day. In the period of 30-60 days, the lambs in the second group realized an average gain of 322 g/day while the lambs in the first group realized an average gain of 202 g/day. On the whole period of lactation, 60 days, the lambs in the second group realized and average gain of 322 g/day while the lambs in the first group realized an average gain of 213 g/day.
