Inbreeding depression in Zebu cattle traits [PDF]
Journal of Animal Breeding and Genetics, 2016 SummaryThe productivity of herds may be negatively affected by inbreeding depression, and it is important to know how intense is this effect on the livestock performance. We performed a comprehensive analysis involving five Zebu breeds reared in Brazil to estimate inbreeding depression in productive and reproductive traits.
