Comparison of Red Angus and Hereford primiparous cows based on the production parameters

The aim of the study was to compare RedAngus and Hereford primiparous cows based on the age at first calving and body weight as well as to compare some indices of fertility, lactation yield and selected zoometrical measurements. The research was conducted on the farm located in the West Pomerania Province. The age at first calving (AFC) and the variability of body weight were similar for both breeds. The primiparous Hereford cows were characterized by significantly (P ≤ 0.01) higher estimated lactation yield (2054.9 kg) compared with primiparous Angus cows (1992.8 kg) and significantly (P ≤ 0.01) higher values of zoometrical parameters: hip height (suitably: 135.5 cm i 132.5 cm) and chest girth (suitably: 197.0 cm and 191.6 cm).
