Abstract

The present study was carried out to investigate the effects of different forms of zinc (no zinc, ZnO and Zn-Met) and Butyric acid on internal egg quality traits and Performance in Hy-Line W36 strain laying hens using 144 chickens from 74 to 83 weeks of age in the second phase of laying. A complete randomized block design with 3 × 2 factorial arrangement with six treatments, six replicates and four layers per replicate for nine weeks was used. Performance parameters were measured daily and quality traits were measured in three periods of age. The results of the experiment showed that the main effects of organic acid and three forms of zinc on egg production, defective eggs, egg weight, egg mass, feed conversion ratio and daily feed intake were not significant during the whole experiment. During the period of 74 to 77 weeks, feed conversion ratio for the treatment containing mineral zinc and organic acid was higher than other treatments (P<0. 05) except for treatment containing organic zinc without organic acid. During whole period, shell thickness was higher in treatments containing organic zinc and acid treatments containing mineral zinc without organic acid (P<0. 05). Crude ash content in treatments containing mineral as well as in the treatment without organic acid was higher than other treatments during the whole period (P<0. 05). Based on the findings of this study, it can be concluded that the use of organic acid and zinc resulted in higher shell eggs thickness.
