Abstract

Linear type scoring is an important tool in herd decision-making, as it aids in selecting animals with superior productive potential based on body conformation. The present study was conducted on 150 lactating Sahiwal cattle, with measurements for linear type traits recorded before the evening milking at three different stages of lactation. The mean scores (±SE, cm) for objective linear type traits were as follows: stature 5.77±0.08; chest width 4.59±0.10; body depth 5.24±0.10; rump width 5.56±0.09; rump angle 4.48±0.08; rear legs sets 4.81±0.12; foot angle 4.84±0.10; fore udder attachment 4.85±0.11; rear udder height 5.52±0.10; udder depth 5.31±0.08; rear udder width 4.27±0.09; central ligament 4.01±0.09; fore teat length 3.49±0.10; rear teat length 3.94±0.09; teat circumference 4.20±0.11; teat diameter 4.16±0.10 and udder balance 5.25±0.11. For subjective linear type traits (1–9 scale), the mean scores were angularity 4.69±0.09; rear leg rear view 5.05±0.06; body condition score 6.53±0.08; locomotion 4.88±0.06; fore teat placement 4.41±0.07 and rear teat placement 6.28±0.08. Based on these findings, dairy cattle may be prioritized for selection with emphasis on improving rump height, body depth, chest width, rear udder width, fore udder attachment, and central ligament strength to enhance overall productivity and longevity.
