Effects of different levels of copper sulfate on performance in Japanese quail (Coturnix coturnix japonica)

Abstract

The main purpose of the current study was to investigate possible Effects of different levels of copper sulfate on performance in Japanese quail. Four hundred, day old male Japanese quail were randomly allocated into 5 treatment groups and 4 replicates (each treatment included 20 replicate). All birds received basal diet until 7 days of old. Birds were received experimental diets from day 8 to 42 of the study. Group A (control) received no supplemented diet, whereas B, C, D and E groups were received basal diet supplemented by 50, 100, 150 and 200 mg copper sulfate, respectively. Body weight (gr), Body weight Gain (BWG) (gr), Food intake (gr) and Food Conversation Ration (FCR) were determined in three phases: phase one from days 0-7, phase two 7-21 and phase three 21-42 of the study. Carcass characteristics (Brest, Drumstick, Gizzard percent and total Intestine length (Cm) were determined at the end of the study. According to the results, there was no significant results on performance in birds fed supplemented diets with different levels of copper sulfate (50, 100, 150 and 200 mg) at any stage of the study (p>0.05). Furthermore, no significant results was observed on performance in Japanese quail fed diets supplemented with copper sulfate (50, 100, 150 and 200 mg) at day 42 (p>0.05).
