Cow liveweight has a strongly negative economic weight on farm profit because a high proportion of feed in dairy herds is required for maintenance (Vercesi Filho et al., 2000). Crossbreeding Bos taurus and Bos indicus is a generalised practice in Brazil (Madalena, 1998). Although Holstein and Gir are the most popular breeds, Jersey and Brown Swiss are also locally available and a trial was set up to find out whether crossing with Jersey or Brown Swiss could further improve performance over the HF/Gir crosses. This paper reports on the female liveweights of that trial.
