Claw Lesions Causing Clinical Lameness in Lactating Holstein Frisian Crossbred Cows

الملخص EN

The objective of this study was to identify claw lesions causing clinical lameness in lactating Holstein Frisian (HF) crossbred cows in dairy cattle.

Seventy dairy farmers were interviewed at the monthly meetings of Progressive Dairy Farmers Association of Ludhiana, Punjab, India.

Ten dairy farms were randomly selected as per probability proportional to size and a total of 450 lactating HF crossbred cows were taken into the study.

All the lactating cows were scored for locomotion and rear leg view index.

Trimming was done in all the clinically lame animals (animals with locomotion scores 2 and 3) and equal number of animals selected randomly from those with locomotion scores 0 and 1.

Various claw lesions were evaluated in both the groups.

There was a significant relationship between locomotion score and rear leg view index to identify lameness.

Sole ulcers and white line fissures were the lesions responsible for clinical lameness.

Other lesions did not cause clinical lameness but increased the asymmetry in lactating HF crossbred cows.

Both locomotion score and rear leg view index could be reliably used to identify clinical lameness in lactating cattle.
