摘要：
The research was carried out on a population of Polwarth sheep, intensely inbred belonging to the Research and Development Institute for Sheep and Goats Breeding, Palas - Constanta. Morpho-productive indices, reproduction indices, current number compared to the one acquired in 1995, inbreeding depression, intergenerational depression, inbreeding population, body weight differentiation and quantity of wool in the year of acquisition compared to 2020 were determined. From the presented data it results that the reproduction of the sheep was not affected instead in rams the body weight and the amount of wool decreased. Surprisingly, instead of shrinking and disappearing over time, the herd has increased and continues to grow, contrary to what is known to date from the effect of intense inbreeding on a breed of sheep.
