Abstract
This study was undertaken to study morphometric analysis of udders and teats' relationships to milk production of Crossbred cows during the lactation stage. The research was carried out on 28 crossbred dairy cows under Sudanese conditions at the farm of the University of Khartoum, Sudan. The udders were studied by udder-shaped and teat-shaped. In addition to udder measurements of udder length, width, and depth, and teat measurements of teat length, width, and distance between teats, milk yield is also measured. The results indicated that the globular udder was the most common type (44%), followed by the bowl (39.33%), pendulous (10.66%), and goaty (6%). Similarly, cylindrical teats were more common (35.66%), followed by teats shaped as bottles (28.33%) and pears (20%), and funnel-shaped (12%) teats were the least common.
Additionally, the pear-shaped teats represented the highest length (6.92 cm), and the funnel-shaped teats represented the lowest length (6.18 cm). In cows with primiparous parity, the frequency of bowl-shaped and goaty-shaped udders was high (38.47%) and (30.76%). while, in multiparous cows, the frequency was lower (26.66% and 6.66%), respectively. Moreover, the pendulous-shaped and globular udders demonstrated a rise in udder frequency in the primiparous (15.38%) and (15.38%) cows and increased advancement in multiparous (40.02%) and (26.66%) cows, respectively. The average milk yield/day recorded was 9.13 ± 0.22 L) per cow, higher milk yields were observed in the bowl-shaped udder (10.57 ± 0.46) and cylindrical-shaped teat (9.59 ± 0.17). Therefore, the udder- and teat-shaped measurements and the selection of the udder and teat shape could be used as important criteria in selecting high-quality cows for milk production.
