Abstract
   In order to determine the effect of conducting the process of body growth and development on the Karakul of Botoșani breed lambs, two lots were organized, in which the experimental treatment was represented by the fact that only one lot benefited from improved feeding and maintenance conditions, the other lot being maintained throughout the lactation period together with the mother sheep.
   The statistical processing of data obtained from the weightings performed in the lots that have benefited from different experimental treatments during nursing period shows a more intense rate of body mass accumulations in the lot that benefited from a directed growth realized in a separate space in which they received additional food resources. At the age of 60 days in the group that benefited from an improvement of the comfort conditions but also from an additional feed, the average body weight was 18.970 ± 0.106 kg while in the group of females kept in common compartments with the mother sheep this parameter was smaller, namely 15.710 ± 0.160 kg. The difference in body mass between the average values determined for the two groups based on the live weight determined at the age of 60 days was 3.26 kg and had a high statistical significance level for P <0.05.
   At the time of weaning, near the age of 90 days, the same aspect is observed, meaning that the weight had higher average values also in the lambs who benefited from an improvement of the maintenance technology, the difference between lots being +2.44 kg and was significant for P <0.05.
   All the data obtained as well as the statistical significance of the differences between lots confirms that the extension of this practice can have favorable effects on the degree of body development, the increase of precocity and on the significant improvement of the main indices of reproduction.
