| Summary: | Novelty of the research: 1. Using pure and cross breeding methods competitive genotype of Lithuanian White pig was formed. 2. Method of mixed linear model multivariate analysis was used and heritability of pig productive traits was evaluated in one farm conditions. 3. Genetic evaluation of Lithuanian White breed structure – boars’ lines and sows’ families- was performed as well as their productive traits correlations were determined for the first time in country. 4. For the first time in Lithuanian pig husbandry computerized method for determination of „muscle eye“ area was used. Practical meaning of the work: Using advantages of pure breeding and applying Large White breed „blood infusion“ was created consolidated meat genotype of Lithuanian White pig with high heritability of muscularity, which is used for genetic improvement in other Lithuanian White pig breed farms. At the moment 90 % of best BLUP method evaluated Lithuanian White pig breed boars and sows are kept in UAB „Berka“.
