2010, 11 (2) p. 159-163
The analysis of Polish Primitive Horse reproduction, in the stable breeding in Dobrzyniewo, was carried out in the period 1993/1994 – 2003/2004. On the basis of the carried out analysis it is evident systematic increase (positive trend) of basic coefficients of reproduction (foaling, fertility, fecundity, birth) and a decrease of coefficients of infertility and abortions. On the other hand leading sires were stallions: Mikrus and Jehol, which were utilised in reproduction for the period of 11 years while mares covered by these stallions had relatively high coefficients of reproduction.
