The objective of the present study was to evaluate/compare the sensory attributes of eggs and meat, egg qualities, proximate composition of eggs, and semen qualities of slow growing native (Miri and Mizo-local) and fast growing improved chicken varieties (Gramapriya and Vanaraja) under hill ecosystem of northeastern India. Significantly higher egg weight, egg volume, and albumen volume were observed in Gramapriya followed by Vanaraja, Mizo-local, and Miri chickens. However, yolk volume was significantly higher in Vanaraja and Gramapriya varieties as compared to native chickens. Yolk to albumen ratio was significantly lower in Gramapriya as compared to Vanaraja and Miri chicken. Consumer liking of eggs for aroma, flavor, and overall acceptability of Miri, Mizo-local, and Vanaraja were significantly higher than that of Gramapriya. Genetic groups did not differ significantly in appearance and proximate composition of eggs. No significant differences were observed between various genetic groups for sensory attributes of meat samples. Semen volume was significantly (p < or = 0.01) lower while sperm concentration was significantly (p < or = 0.01) higher in native chicken as compared to the improved chicken varieties. However, pH, mass activity, sperm motility, and livability did not differ significantly among genetic groups although Mizo-local had significantly higher abnormal sperm count. The study concluded that the genetic groups with different growth rate differed significantly for various egg quality parameters and semen characteristics but not for sensory attributes of meat and proximate composition of eggs.
