I have made it clear on many occasions that the selection criteria being used by the Bonsmara Society (in particular Phase C growth and FCE) and now being followed by other breeds is NEGATIVE:
- Growth and feed efficiency as measured in the Phase C test is negatively correlated to Inherent Body Condition.
- A major determinant of cow fertility is body condition. The ICP for the daughters of the “best” performing bulls (Gold Merit) is 19 days LONGER than those of the “poorest” (Sub-Merit) bulls. This a 5 pc difference in calving rate in favour of the worst performing bulls. We can only imagine how fertile the daughters of the slaughtered bulls could be.
- If fertility is the most important trait required by cattle, why entertain an expensive test that is, at the least, not conducive to higher fertility?
- The person who is going to address the issue of whether a Phace C test is appropriate is the same person who, with encouragement from Prof. Jan Bonsma, initiated the test. I quote him: “In order for cattle to compete with pigs and chickens in converting grain to meat we need to select for Phase C FCE”. In other words he is the mastermind in making an inefficient “pig” pit of a ruminant.
- The truth is very simple to understand UNLESS ignorance is fueled by arrogance in order to inflate “important” egos.
