Egg quality parameters of local chicken genotypes in crop and livestock-based diversifications

Abstract

A study was carried out to analyse the egg quality parameters of local chicken genotypes such as village chicken and naked-neck chicken under crop and livestock based diversification systems. The results of the study revealed that all selected egg quality parameters of both chicken population was significantly differed (P<0.05) in all diversification systems. Significantly better results found in crop based diversification system for both village and naked neck genotypes in egg weight (49.16±1.07 and 51.43±1.97 respectively), egg shape index (75.23±1.32 and 75.33±1.36 respectively), specific gravity of egg (1.15±0.01 and 1.18±0.001 respectively), egg hatchability (89.24±1.67 and 89.22±2.09 respectively), albumin weight (28.62±1.64 and 30.70±1.87 respectively), yolk weight (17.17±1.05 and 17.64±1.22 respectively) and egg shell weight (17.17±1.05 and 17.64±1.22 respectively). The egg fertility (80.11±2.73 and 75.74±2.13 respectively) and egg shell thickness (0.312±0.003 and 0.317±0.001) were significantly higher in the livestock based diversification system for both

village and naked neck genotypes. village chicken was significantly

The calculated yolk: albumen ratio for highest (0.62±0.01) (P>0.05) under

livestock-based diversification system while in naked-neck chicken it was significantly higher (0.57±0.02) in crop-based diversification system. From the results, it was concluded, both the population performed well in crop based diversification systems in terms major egg quality traits.
