Increasing the production of mutton and goat meat is essential for the food security of the Russian Federation, therefore, studies on early mating of animals are relevant, since early mating allows more offspring to be produced at an earlier date. The aim of the study was to compare the reproductive qualities, growth and development characteristics of goatlings when they are mated at 7 months of age and at 18 months of age. It was found that an experimental group of two-years-old goatlings outperformed the controlled group of one-year-old ones in all the measurements, but significant differences were found in the oblique body length and chest width. Goatlings at two years of age compared to those at one year of age had a more compact and massive body with a broader chest. In the group of goatlings of 30 heads (n=30) born at seven months of age, 27 or 90% live kid goats were born. At the same time, the average live weight of goats at birth hatched at 18 months and 7 months differed insignificantly. Thus, early mating does not negatively effect on their growth and development, and allows additionally getting 90 kid goats per 100 goatlings.
