Having a balanced ration available will also reduce rooting behavior. 4. factors affecting water consumption dry feed intake water/dry feed, Breeding and hybrid vigour L.O. Provision can be made for breeding large boars to gilts or small boars Purebreds are eligible for registration. Internal parasite issues can be severe on poorly managed pasture systems. Crossbreeding is mainly used for commercial production. It provides opportunity to produce good quality bull for breeding.
