Document Summary
European union 21. 3: made up of 27 countries. Immature female pig: has not had first litter. Stag: male pigs that are castrated after sexual maturity. Purebred hogs are used to create better hybrids for pork production: a mix of a colored male and white female to have more piglets that will be larger and more muscular. A common practice for swine industry integrators. The farm purchases all breeding stock: maternal pigs: hybrid gilts, terminal pigs: hybrid boars. All offspring that go to market are three way crosses. Large integrators have herds that produce their own females: they have their own genetics. Make sure they are structurally sound and have the ability to walk: leg soundness scores are 50% heritable, confinement housing may intensify any problems. Mammary soundness: nipples evenly spaces, functional teats. Eliminate the pss stress gene: major cause of low quality pork, pse in the pork carcass. Select boars and gilts to best fit your production needs.
