Abstract

Body condition score (BCS) is a non-invasive visual estimate of the amount of subcutaneous fat deposition in dairy cows and is assessed independently of body weight and stature. Its main use is in managing the nutritional status of cows at calving, mating and drying off. BCS is considered as a useful tool in predicting the productive and reproductive performance of dairy cows (Wildman et al., 1982). The objectives of this study were: 1. Estimate genetic parameters for BCS and the genetic relationships between BCS and other traits of interest in New Zealand dairy cattle population, and  2. Investigate the use of random regression models to estimate genetic parameters in the first lactation
