| Popis: | The aim of this study was to perform analysis genetic trends of traits of milk production in select herds of the Slovak spotted breed. The genetic gain for milk, fat and proteins production in kg was calculated by different methods. Genetic trends were between 68.31 - 109.11 kg for milk production, 2.98 - 5.44 kg for fat production and 2.26 - 3.46 kg for proteins production. Increase of inbreeding was estimate 1.520 - 1.860 - 3.190 % behind generation. Prediction genetic trends by „Truncation“ selection was 12.2 to 111.6 kg for milk at fathers of daughter and 29.2 to 96.1 kg for milk at mothers of daughter. |
