THE EFFECT OF OIL AND RAPE OIL MEAL USED IN LAYING HENS NUTRITION

Abstract

The effect of using rape oil and meal in laying hens feeding was established on three groups of 27 laying hens from the Rosso SL hybrid each, with an initial age of 31 weeks, maintained in identical technological and microclimatic conditions and fed with isocaloric and isoproteic ratios. The difference in the forage structure consisted only in the substitution of sunflower oil with rape oil at the first experimental group and the sunflower meal with rape meal at the second experimental group. The productive effect of rape oil and rape meal was established on the basis of daily egg production and egg mass, egg size, the evolution of hen body weight. The nonsignificant and extremely reduced differences recorded for the control group show the high nutritional value of rape meal and oil meal, which can replace sunflower oil and meal in laying hens feeding.Â
