The objective of this study was to compare the efficacy of human chorionic gonadotropin (hCG) for the stimulation of ovulation within 48 h after treatment in mares, which had a ≥35 mm follicle. A total of 41 oestrus cycles of 21 mares (9 Thoroughbred, 6 Dutch Warmblood, and 6 Friesian), between 7 and 12 years of age were used for this study. All the mares were intramuscularly treated with Hcg, at the dose of 3 000 IU when a follicle ≥35 mm was detected. They were examined daily by transrectal ultrasonography, until the ovulation was confirmed. It was found that the diameter of follicle before ovulation was more significant, and oestrus duration was longer in Friesian mares than those of Thoroughbred and Dutch Warmblood ones. Moreover, the percentage of mares ovulating within 48 h after hCG treatment was significantly lower in Friesian mares, when compared to that of the other breed mares. There was no significant difference in these parameters between Thoroughbred and Dutch Warmblood mares. In conclusion, the efficacy of hCG may be different among mares of different breeds. The percentage of ovulation within 48 h after hCG treatment was lower in Friesian mares when compared to the other breeds. Therefore, various strategies are needed for the stimulation of ovulation in Friesian mares.

The aim of the study was comparison of the milk performance of primiparous cows from 6 European countries with Polish Holstein-Friesians, as well as to demonstrate the differences within the different genetic groups. Material consisted of data contained in the dairy reports gathered from 26 farm “Healthy Cow” project. The analysis involved data including milk yield and its chemical composition, i.e.: fat, protein, lactose, solids, and urea somatic cells count in milk. On the basis of these results, it was found that the country of origin had significant impact on daily milk yield, % fat, % protein, % of lactose and also affected dry matter content, urea and somatic cells in the milk of lactating cows. Research reviled that there were not differences in milk performance between imported and native cows. However, the breed of cows had an strong impact on daily milk production, % protein, % lactose,% dry weight, as well as urea content and somatic cells count.

The investigations were aimed at the determination of genetic distance among eight lines of laying hens kept in Poland and belonging to the following breeds: GreenLeg ZKF and Z11, Leghorn H22 and G99, Rhode Island Red RD2, YellowLeg Ż33, Polbar (Pb) and Sussex (Sx). The phenotype frequencies of fastmigrating prealbumin (PaF), eggyolk transferrin and ovalbumin (OvA), ovoglobulins: G3, G4 and G2 and conalbumin were obtained from the electrophoregrams of horizontal polyacrylamide gel electrophoresis.
