Abstract:
The study aimed to find the relationship among udder, teat type traits and milk production traits in Sahiwal cows. Hundred lactating cows from Livestock research farm in ICAR- NDRI, Karnal, India were chosen for the investigation. The value of the Pearson’s linear correlation coefficient defined by the Greek alphabet rho (Γ) determined the level of relationship between the traits achieved using the correlation procedure (PROC Corr) (SAS). High positive correlation (p <0.05, p<0.01) was found between Udder Length & Udder Depth (0.99), Udder Length & Udder Balance (0.99), Udder Depth & Udder Balance (0.99) and Teat Length & Teat Circumference (0.529). Moderate yet significant values of correlation were there between Udder Length & Central Ligament (0.373), Udder Length & Average Distance between teats (0.373), Udder Length & Shortest distance from teat ends to floor (0.34), Rear Udder Height & Udder Balance (0.43), Udder Width & Udder Circumference (0.44), Lifetime Milk yield & 305 Days Milk yield (0.44) and low correlation between 305 Days Milk Yield & Udder Length (0.28), Udder Width (0.323). On the other hand, significant negative correlation between, Fore Udder Attachment & Rear Udder Height (-0.33), Udder Width & Central Ligament (-0.23), Teat Diameter & Udder Depth (- 0.248) and 305 Days Milk Yield & Udder Depth (-0.43) was observed. The indirect selection of Sahiwal cows based on the findings of the study will facilitate the process of decision-making in selection for improved udder confirmation traits and milk production in cows.
