The optimization of ginger and Zinc in feed to preventing heat stress at tropical in local duck

Abstract

This study aimed to determine the optimization ginger flour supplementation and zinc minerals in feed on the performance, carcass, abdominal fat and the weight of the physiological organs of local ducks that experience heat stress at tropical temperatures. This research method is an experimental with Randomized Block Design (RBD) 4 treatment with 5 groups of body weights as replications. Treatment in this study was A (feed + ginger flour 0% + zinc 0 ppm, as control), B (feed + ginger flour 1% + zinc 40 ppm), C (feed + ginger flour 3% + zinc 40 ppm), D (feed + ginger flour 5% + zinc 40 ppm). The results showed that supplementation of ginger flour and zinc minerals in the feed had a significant effect (P<0.05) on performance of body weight, conversion, percentage of carcass and abdominal fat, but had no significant effect (P>0.05) on the physiological weight of local ducks in heat stress at a temperature of 33-34°C. The results of this study concluded optimization of ginger flour and zinc mineral supplementation in the performance, carcass, abdominal fat and physiological organ weights in heat stress were obtained on feed by giving 3% ginger flour and 40 ppm zinc minerals.
