Efficiency of pig production depends on the reproductive performance of sows and growth rate of piglets, which in turn is indicative of their genetic potentiality. Though, there is a vast population of indigenous pigs in India, their productive and reproductive potentials are low. To augment the production levels of indigenous pigs, crossbreeding with exotic breeds has been initiated under the aegis of All India Coordinated Research Project on Pigs for last more than 2 decades. Introduction of exotic inheritance in to desi pigs improved the performance of pigs markedly. Performance of these crossbreds is likely to differ in different agroclimatic conditions. Body weight and body conformation also have considerable importance to decide the selection criterion for improving the overall productivity of pigs. The book "Genetic study of economic traits in crossbred pigs in India" deals with evaluation of the performance and genetic parameters of 50% and 75% Large White Yorkshire crossbred pigs with respect to various productive and reproductive traits.
