Comparative Gross Biometrical Parameters of Deep Pectoral Muscle of Kadaknath, Narmada Nidhi and Jabalpur Colorbirds

The experiment was conducted to investigate gross biometrical parameters of deep pectoral muscle of Kadaknath, Narmada Nidhi and Jabalpur Color birds at 6 and 10 weeks of age. The present experimental work was conducted on total 36 male birds of Kadaknath, Narmada Nidhi and Jabalpur color. The birds were categorized into two age groups: 6 weeks and 10 weeks of age of Kadaknath (G1 and G2), Narmada Nidhi (G3 and G4) and Jabalpur color (G5 and G6), respectively with six birds in each group. Birds were procured from All India Co-ordinated Research Project on Poultry (AICRP), Livestock Farm, Adhartal, NDVSU, Jabalpur (M.P.). Gross biometrical parameters i.e. length, width, thickness and cross-sectional area of deep pectoral muscle was measured. The intensity of color of deep pectoral muscle was increased at the age of 10 weeks. The gross biometrical parameters were maximum in Narmada nidhi birds at 6 weeks of age showing its initial growth while at 10 weeks it was maximum in Jabalpur color birds. Among all birds, the highest cross-sectional area was noted in Jabalpur color birds at 10 weeks. All parameters in Kadaknath fowl were significantly lower than in the other two breeds, indicating reduced growth during this age group.
