Evaluation of Reproduction Traits in Selected Breeding Herds of Slovak Simmental Dairy Cows by Breeding Type
Keywords:Slovak Simmental cattle, dairy cows, reproduction traits, breeding type, coefficients of determination, correlations
The aim this work was analyse reproduction traits in selected breeding herds Slovak Simmental dairy cows in the period 2012 to 2016 by breeding type (S0, S1, S2) the results for dairy cows: DFS, DO, NIC and CI. The basic statistical analysis were analysed using the SAS version 9.3 (TS1M2). For the actual computation a linear model with fixed effects was used: yijklm = μ + HYSi + bj + ck + eijkl, where: μ = mean value, HYSi, bj = sire, ck = effect of bull, eijkl = residual error. The basic traits of reproduction traits (DFS, DO, NIC, CI) in selected breeding herds Slovak Simmental dairy cows were 78.55 days, 120.83 days, 407.02 and 2.14 times for S0, 78.62 days, 124.82 days, 408.76 and 2.04 times for S1, and 80.99 days, 124.07 days, 410.90 and 2.20 times for S2. The linear model to represent coefficient determination R2 = 0.482750 % for DFS, R2 = 0.435010 % for DO, R2 = 0.345971 % NIC and R2 = 0.482750 % CI with all fixed effects. The analyses by the effect were the highest effect of HYS than effect of sire. These effects were statistically high significant (P<0.0001).
