Feeding to Achieve Genetic Potential

The choice of genetic lines is important since it sets the ‘ceiling’ or upper limitfor pig performance. It is well known that poor environment and impropermanagement lowers the operational ceiling for reproduction and growth. This isbest illustrated for growth but examples are emerging for the sow relative toNutrition and pig output. This paper is devoted to a discussion of how Nutritionconstrains the expression of Genetic potential for growth and reproduction.Brief mention is made of the impact of sub-clinical disease management sinceit, rather than Nutrition, is probably the first limit to expression of GeneticPotential for growth during grower and finish phases.
