Effects of organic and inorganic zinc supplementation in breeder hen rations on performance and egg quality

Abstract

In this study, the effects of two forms of zinc minerals (organic and inorganic) supplemented to rations for laying breeder hens were investigated relative to body weight, feed intake, feed conversion ratio, egg production, external and internal quality of eggs and egg weight. This 16-week study, which used 216 Barred Rock hens, was initiated when the hens were 48 weeks old. The animals were fed basal diet which is consist of 17% crude protein and 2800 kcal/kg metabolisable energy. The control rations were prepared using a zinc-free mineral mix. The other five treatments received 60 mg/kg of one of the following zinc supplements: Availa-Zn’, ZnSO4, Zinc RedoxMin, ZnO and ZnCl2. It is concluded that (1) Zn-Avila added to rations had negative effects on feed consumption, egg shape index and eggshell strength; (2) the ZnSO4 supplement had positive effects on egg shape index, albumen index and Haugh units; (3) the Zn-RedoxMin supplement had positive effects on egg weight and egg shape index but negatively affected albumen index and Haugh units; and (4) the ZnCl2 supplement had positive effects on feed conversion and eggshell strength, but it reduced the value of the index figure.
