7,8,9, Vitamins

It is well established that in commercial poultry operations today there are benefits from the routine use of higher levels of vitamins in feed than recommendations published in reviews such as NRC 1994. Today’s elevated levels not only help ensure simple deficiencies are rare, but also help the bird cope with the increased stress and disease challenge of commercial production. In addition, they also go someway towards allowing the bird to fully benefit from the significant changes in genetic potential management practice and in dietary ingredient usage following the challenges of consumer pressure. Recent data on vitamin requirements of the modern bird suggests that in some, particularly stress, situations there may be benefits of still higher levels of routine supplementation of certain vitamins.
