Abstract
ABSTRACT Karan Fries (KF) cattle is India's newly developed dairy breed with high production potential. The present study was undertaken to evaluate 17 linear-type traits, behavioural and functional traits for estimating the genetic parameters and to find their association with production performance in KF cattle using a multi-trait Bayesian animal model. Among linear-type traits, stature, chest girth, body length and body depth had a high positive genetic and phenotypic correlation (ranging from 0.30 ± 0.01 to 0.74 ± 0.03) with production traits (total milk yield and 305 days milk yield). The majority of the linear-type traits, milking temperament and milking speed were moderately heritable (ranging from 0.25 ± 0.04 to 0.40 ± 0.03), while days open had low heritability (0.20 ± 0.25). This study showed the importance of reliable assessment of genetic parameters and incorporation of a few linear-type traits having high heritability and genetic correlation with production traits, can be utilized for future selection and breeding programmes in KF cattle.
