Effect of dietary copper sulphate on the performance of growing Japanese quail

SUMMARYThe effect of 200, 400 and 600 mg dietary copper sulphate/kg was studied in 64 Japanese quail (Coturnix coturnix japonica) in 1987. The results indicated that addition of 200 or 400 mg/kg to conventional diets of quail 7–42 days old significantly increased (P < 0·05) body weight gain and significantly decreased (P < 0·05) feed intake. There were significant (P < 0·05) increases in carcass, breast and leg weights in some cases; the first two characters had the highest values in the quail fed the diet containing 200 mg Cu/kg. The addition of 600 mg Cu/kg to the diet had an adverse effect on liver weight compared with the addition of 200 and 400 mg/kg. Copper concentration in the liver was not influenced by any rate of copper supplementation.

Abstract. The objective of this study was to investigate the effect of sex of Japanese quails (Coturnix coturnix Japonica) on fattening performance and carcass characteristics. The quail chicks were divided into three groups, made up of 96 males or 92 females or 36 individuals of each sex, resulting in a total of 256 chicks. The chicks in the groups were raised using the same feeding regime (24% CP, 2900 kcal/kg ME) and housing conditions for 42 days. There were significant (P<0.01) differences between male and female groups in weekly live body weight (lbw) gain values on day 35, in average live body weight gain on days 35 and 42, and in lbw gain values between days 14 and 42. Slaughter weight and liver weight were significantly different between groups (P<0.01). The differences between the two sex in mixed group in average body weight gain, average lbw on days 35 and 42, average lbw gain, lbw gain between days 14 and 42, slaughter weight, hot carcass yield, and liver weight were found significant (P<0.01). Lbw, lbw gain, feed consumption, slaughter weight, hot carcass yield, weights of heart, liver and giblets were higher in female quails while feed conversion rate was lower. As a result, these data suggest that separate raising of male and female Japnese quails might be more advantageous.

The aim of the study was to evaluate the influence of different light sources on organ characteristics, bone development, chemical body composition and hepatic function of female Japanese quail (Coturnix coturnix japonica) in different reproductive ages. In total, 210 female 1-day-old birds were housed in a brick shed, which was divided into six rooms during 12 weeks. Each room was equipped with a different type of light bulb (incandescent; compact fluorescent; and white, blue, red and green light-emitting diodes (LEDs)) and contained seven cages with five birds in each. The light intensity was 15 lx and the photoperiod was 23 h light and 1 h dark (23L:1D) during the first week, 10 L:14D from the second to the fifth week, and 17L:7D until the end of the experiment. The experimental design was completely randomised, with six treatments and seven replicates of each bird. The morphophysiological conditions of the birds were evaluated at the beginning (8 weeks) and during peak production (12 weeks). At 8 weeks, a higher intestine weight and length and liver weight were observed in birds maintained in white LED (P < 0.05). Lower breast weight (P < 0.01) was also observed with this type of lamp. White and red LEDs decreased (P < 0.05) the percentage of ash in the tibia, but this reduction did not affect (P > 0.05) bone resistance. At 12 weeks, higher bone resistance was obtained (P < 0.01) with white LED and higher eye diameter was observed (P < 0.05) with incandescent and white LED lamps. There was no influence (P > 0.05) of light sources on the circulating levels of aspartate aminotransferase and alanine aminotransferase. Fluorescent bulbs resulted in the highest (P < 0.05) level of γ-glutamyltransferase, while blue LED resulted in the lowest level. There was no influence (P > 0.05) of light sources on chemical body composition in any of the evaluated ages. It was concluded that the photostimulation of Japanese quail with white LED is more efficient to stimulate their organ development, especially the intestine, until 8 weeks of life, resulting in birds with better bone development during peak production.
