    Genetic parameters for test-day model with random regressions for milk production traits of Czech Fleckvieh cattle

  • Original language description

    The multiple-lactation test-day model with random regressions specific to genetic effects of animal and to permanent environmental effect was applied to test-day milk yields records in the first 3 lactations of the Czech Fleckvieh cattle to estimate genetic (co)variances. The estimated heritabilities for milk yield were 0.26, 0.23 and 0.24, for protein yield 0.20, 0.21 and 0.24, for fat yield 0.21, 0.20 and 0.23 in the 1st, 2nd and 3rd lactation, respectively. The genetic correlations between lactationswere for milk yield 0.86, 0.76 and 0.89, for protein yield 0.83, 0.67 and 0.88, and for fat yield 0.84, 0.73 and 0.86 between 1st-2nd, 1st-3rd and 2nd-3rd lactation, respectively.

    Genetické parametry pro test-day model s náhodnou regresí pro znaky mléčné produkce u českého strakatého skotu

  • Czech description

    Třílaktačním test-day modelem s náhodnou regresí popisující genetický efekt jedince a efekt permanentního prostředí byly odhadnuty genetické variance a kovariance pro produkci mléka u prvních 3 laktací českého strakatého skotu. Odhadnuté dědivosti pro produkci mléka byly 0,26, 0,23 resp. 0,24, pro produkci bílkovin 0,20, 0,21 resp. 0,24 a pro produkci tuku 0,21, 0,20 resp. 0,23 u 1., 2. resp. 3. laktace. Genetické korelace mezi laktacemi byly pro produkci mléka 0,86, 0,76 resp. 0,89, pro produkci bílkovin 0,83, 0,67 resp. 0,88 a pro produkci tuku 0,84, 0,73 resp. 0,86 mezi 1.-2., 1.-3. resp. 2.-3. laktací.
