The last question in the foregoing checklist is a very interesting one to ask.Salesmen may have instructed not to denigrated the opposition.If so,accept it as part of selling ethics.But you never know-by judicious questioning I have obtained some useful and important cross-confirmed data on various genetic lines which diplomatically I will not publish here,and there is no reason why you cannot do the same.
For example,data from 7 to 8 sources have revealed important advantages between various commercial blood lines in the areas of :
Meat per Ton of Food on the same carcase yield.
Leg strength and Appitite under hot conditions.
Feed Protein needs in the last month before slaughter.
Loading and haulage stress.
Docility.
Presence of marbling genes e.g. 0.7% marbling fat v 1.3%.
Killing out percentage e.g. +1% ~-1% under identical conditions
這是出處,研究一下吧 |
