Ferula eleaochytris Powder Effect in Layer Diet on Feed Intake and Some Egg Parameters Using a Multivariate Analysis Method for Repeated Measures

Abstract

Sahinler, S., Sahin, A. and Gorgulu, O. 2005. Ferula eleaochytris powder effect in layer diet on feed intake and some egg parameters using a multivariate analysis method for repeated measures. J. Appl. Anim. Res., 28: 29–33.

A study was carried out to test the effect of Ferula eleaochytris root powder (FE) on feed intake and some egg parameters of laying hens by using the multivariate test for repeated measures. FE treatment affected fresh egg shell weight (P<0.05), dry egg shell weight (P<0.01) and consequently lowered shell thickness (P<0.01) even though FE2 treatment increased feed intake (P<0.05). Egg weight, egg albumen weight, egg yolk weight and egg production were not affected by FE treatment (P>0.05). FE appears to have a negative effect on calcium absorption from gastro-intestinal tract.
