ABSTRACT

The aim of this study was to compare Limousin (195) and Simmental (326) primiparous cows based on the variability of age at first calving and body weight as well as to compare some fertility indices, lactation yield and selected zoometric measurements. The research was conducted on the farm located in the West Pomerania Province. Limousin primiparous cows had a significantly higher (P≤0.05) body weight than did Simmentals. Limousin individuals were characterized by an later age at first calving (P≤0.01). Calving interval (CI) was significantly (P≤0.01) shorter in Simmental females. Simmental animals were characterized by a significantly (P≤0.01) higher estimated lactation yield as well as significantly (P≤0.01) higher values of zoometric parameters (hip height and chest girth) compared with Limousin primiparous cows.

Key words: Limousin, Simmental, body weight, calving interval, age at first calving, zoometric measurements.
