The study was carried out with 1381 ewes from the two main breeding farms of the Pleven Black head breed (PBH) – the flock at the Institute of Forages – Pleven (IF) and the flock of the Agricultural cooperative (AC) in the village of Komarevo, Pleven district. The traits live weight (at weaning, at 18 months and at 1.5 years) and the prolificacy at the first and second lambing were studied. It was found that the live weight of the ewes at all ages in IF was higher compared to that in Komarevo. The live weight for the two flocks was respectively 26.360 and 23.615 кg at weaning, 59.031 and 57.566 kg for the hogs at 18 months of age and 63.553 and 61.161 kg for the ewes at 2.5 years. The prolificacy of the ewes of the studied flocks for the two consecutive lambings was relatively low, especially for the flock in Komarevo. The average values for this trait in the IF flock were respectively 1.25 and 1.30%, and for the flock in Komarevo - 1.18% for both lambings.
