There is an old adage among livestock raisers that holds that blue ribbon-winning animals seldom make good parents, but generally make crackerjack grandparents. The one word answer for why this happens is, I believe, adaptation. A top Texas-bred bull, boar or ram whisked away to our Northern Missouri climes or someone else’s Maine environment is going to struggle to adapt and must go through a time of transition.
This is especially true if the move is made in a time of temperature and weather extremes. The changes an animal can face when moved from point to point on the map are many and varied, and some are too often overlooked in that flurry of activity.
The differences between a Northern Missouri and a Southern Texas winter are quite obvious, but there are also differences in soil types, water composition, ration mixtures and forms, owner temperaments and skill sets, differences in facilities, differences between gene pools, new parasite and disease challenges, different pasture varieties and a great many more.
Quite often, the animals being moved are young, inexperienced and lacking in natural immunities for their new environments. The more artifice and “push” that went into creating that animal the harder it will be for that animal to make the needed changes.
Altitude, for example is a real factor in how beef cattle perform with some lines clearly denoted as “high altitude” cattle. An old and very much kept off the books rule of thumb for swine breeders held that for every young boar going through a test station, a full or half sib should be retained at home to replace it should it fail to perform for the new owner.
The boar grown out in a very small group, fed a very complex and costly ration to accelerate growth in a limited space, living in such a stifling environment, may hang up some real performance figures but then fall apart quickly in the real world of the breeding pen.
In founding a new herd or flock or upgrading or replenishing an existing one it is necessary to look to outside sources for the needed genetic material, the genetic pieces to make corrections and accomplish desired goals. Continue Reading →
