Genetic Improvement of Fat and Proteins Production in Select Herds of the Slovak Spotted Breed

Jozef Bujko, Jozef Pjontek, Cyril Hrnčár

Abstract


The aim this work was to estimate the genetics improvement in selected herds of the Slovak spotted breed. The genetics gain for fat and proteins production in kg was calculated by different methods. Genetics gain was between 3.91 - 5.79 kg for fat production and 3.35 - 4.71 kg for proteins production. Increase of inbreeding was estimated to be 0.867 - 1.098 - 1.987 % behind generation. Prediction genetic gain by "Truncation" selection was 0.327 to 1.038 kg for fat, 0.710 to 1.127 kg for proteins in fathers of daughter and 0.476 to 1.184 kg for fat, 1.007 to 1.452 kg for proteins in mothers of daughter.
