Updated vitamin, trace mineral specifications for broilers
The last publication on poultry nutrient requirements was released in 1994
I have recently seen updates on nutrient specifications for broilers from most major genetic houses. The same goes for some serious vitamin and, surprisingly, trace mineral suppliers. Apparently, broiler micronutrition (vitamins and trace minerals) remains a dynamic field, at least in the commercial world, with few notable exceptions when it comes to academic research. Here, it should be reminded that the last NRC publication on poultry nutrient requirements was released in 1994. Back then, broilers were marketed at 8 plus weeks of age, whereas, fast forward 30 years or so, broilers go to market at 5-6 weeks of age – an improvement of about a week per decade. So, why we still do not have a highly respected authority like NRC review current literature and come up with new recommendations for modern broilers?
