PIC Symposium 2011 | Nashville, TN BIOLOGY of the ‘Very Plastic’ 350 lb-Pig Final Thoughts to Ponder Biological ‘Plasticity’ of the Pig Enables Altering Skeletal Muscle Growth Efficiency and Body/Carcass Composition Without Compromising the Animals’ Biological Viability at Heavy Weights. 2011 Results Clearly Indicate that PIC Full-Program Genetics is Already Economically Producing 350 lb. Commercial Pigs. Commercialization of Producing 350 lb. Pigs Will Require Concerted Efforts of Geneticists, Nutritionists, Production Specialists, Animal Behaviorists, Meat Scientists and Food Engineers to Insure its Success.
