Abstract: The study was conducted on 6 weeks age broilers at poultry unit of Livestock farm complex, College of Veterinary and Animal Science, Navania, Udaipur. The Significant effect (p≤0.05) of stocking densities on carcass traits viz., neck, back, dressing and drumstick percentage were observed. High estmean value of neck percentages were observed in D1 followed by D2 and D3 treatment groups respectively. Back weight percentage was also influenced by (p≤0.05) stocking densities and high estmean value was observed in D2 followed by D3) and D1. There was a highly (p≤0.01) significant impact of dressing percentage among all the three stocking densities. Birds reared at D2 control group stocking, density recorded the highest dressing percentage followed by D1 and D3 group respectively. Like wise significant (p≤0.05) influence of stocking density was observed on drumstick percentages. The highest percentage was found in D2 followed by D3 and lowest in D3 group respectively. However non-significant difference in thigh percentage between birds reared at D1, D2 and D3 stocking densities. Birds reared at the stocking densities of 8, 10 and 12 birds /m2did not differ in breast weight percentages, but had numerically higher value in D3 and D2 group followed by D1. Wing weight percentages was numerically higher in D2 followed by D1 and D3 though statistically insignificant. Gizzard, liver and heart (giblet) percentages were highly and significant (p≤0.01) influenced by stocking density, the high estmean gizzard weight percentages was observed in birds reared at D3 followed by control group D2 and D1 group densities. Whereas liver weight percentage was higher in D2 group followed by D3 and D1 respectively. However, in the present study, stocking density had no impact on the percentage of heart but the numerically higher value was seen in D3 group followed by D2 and D1 stocking densities.
