Khvatova M. Pollialel crossing system efficiency in relation with determination combining ability in pigs

Object of study.Selection process, lines, family, hybrid and related forms, methods of complete and incomplete diallel hybridization, the model prediction of heterosis effect. Purpose of the study. Reproductive ability of sows with clean-bred breeding, fattening and meat quality in crossbred calves under various schemes of complete and incomplete diallel analysis. Methods. Zootechnical, population, genetic, statistical, mathematical, biometric, economic, retrospectively. Scientific novelty of the results. First theoretically grounded and put into practice methods of predicting the reproductive ability of Welsh females breed with clean-bred linear-related and fattening traits at industrial crossbreeding and hybridization of different species by using a mathematical model of the effects of general and specific combining ability set at full and incomplete diallel crossbreeding schemes.The practical significance of the results. Development and implementation method of estimation and prediction of productive features for hog mathematical models to include the effects of general and specific combining ability of lines and families makes it possible to identify the most heterosis combinations.
