Studies on genetic and phenotypic parameters of production and reproduction efficiency traits in crossbred dairy cattle



Studies on genetic and phenotypic parameters of production and reproduction efficiency traits in crossbred dairy cattle



Indian Journal of Animal Research 29(2): 75-78



Data were analysed on reproductive and dairy traits, recorded in 1975-84, on 244 crossbred cows with Friesian, Brown Swiss or Jersey sires and Hariana dams. The hsuperscript 2s of 2 breeding efficiency indices were 0.635+or-0.28 and 0.600+or-0.26. For 8 other traits characterizing dairy performance or reproduction, the standard errors were close to or larger than the hsuperscript 2s values.
