Canine behaviours that are both desirable and undesirable to owners have a demonstrable genetic component. Some behaviours are breed-specific, such as the livestock guarding by maremmas and flank sucking seen in Dobermanns. While the identification of genes responsible for common canine diseases is rapidly advancing, those genes underlying behaviours remain elusive. The challenges of accurately defining and measuring behavioural phenotypes remain an obstacle, and the use of variable phenotyping methods has prevented meta-analysis of behavioural studies. International standardised testing protocols and terminology in canine behavioural evaluations should facilitate selection against behavioural disorders in the modern dog and optimise breeding success …

The objective of this study was to evaluate the genetic and phenotypic parameters for daily milk yield (DMY) in Black Bengal does. Genetic parameters were estimated using a residual maximum likelihood procedure, fitting an animal model while ignoring maternal genetic or permanent environmental effects. The least squares mean for DMY was 354.76 g. DMY was significantly (P < 0.01) affected by parity, litter size, and season of kidding. The heritability of DMY was low (0.15) and the fact that the trait can only be measured in females suggests that progeny testing may be the best sire selection method for this trait.
