Efficacy of phytase for increasing protein efficiency ration values of feed ingredients. Research at the University of Illinois evaluated the effects
of phytase on protein utilization in chicks. Several experiments were
conducted to determine whether phytase would improved the amino acid
digestibility of several feed ingredients including soybean meal, canola
meal, cottonseed meal, peanut meal, casein, wheat middling, wheat bran,
rice bran, defatted rice bran, meat and bone meal and corn gluten meal.
They found that the protein efficiency ration (PER) varied among ingredients,
however, phytase supplementation had no significant (P>0.10) effect
on protein utilization of the various feed ingredients in these chick
growth studies. |
