Abstract

A 35-day experiment was conducted in broilers to study the effect of supplementation of sulphate or hydroxychloride forms of Zn and Cu at two supplemental Zn levels on growth performance, meat yield and tissue levels of Zn. On day zero, 900 male Ross 308 broiler chicks (45±1.10g) were allocated to 4 treatments in a randomized complete block design and 2×2 factorial arrangement of treatments. The factors were two sources (sulphate or hydroxychloride) of Zn and Cu and two levels (low or high) of Zn. The Zn sources were zinc sulphate monohydrate (ZSM) or hydroxychloride Zn. Copper sources were copper (II) sulphate pentahydrate or hydroxychloride Cu. Each of the 4 treatments had 15 replicates and 15 birds per replicate. Birds were weighed on days 0, 21 and 35 for growth performance. On day 35, left tibia bone, liver and blood were collected from four randomly selected birds per pen. In addition, seven birds per pen were used for carcass evaluation. There was no significant source × level interaction on any of the growth performance response. Broiler chickens receiving hydroxyl Zn and Cu had greater (P < 0.05) gain:feed whereas broiler chickens receiving lower Zn level had greater (P < 0.01) weight gain. There was no source × level interaction on meat yield. Broiler chickens receiving hydroxychloride Zn and Cu had greater (P < 0.05) % breast yield than those receiving sulphate Zn and Cu. Higher level of Zn, irrespective of source, produced greater (P < 0.01) tibia and plasma Zn levels whereas liver Cu was greater (P < 0.05) in broiler chickens receiving hydroxychloride Zn and Cu. It was concluded that hydroxychloride Zn and Cu were more efficacious than sulphate Zn and Cu in promoting growth performance and enhancing meat yield in the current study.
