Researchers used a three-point locomotion-scoring system to evaluate 1,450 cows on 19 Dutch dairy farms. The results show these factors were correlated with increased lameness:
|A Dutch study shows that feeding corn silage to heifers was associated with an increased incidence of lameness.|
Presence of a hoof-trimming stall equipped with a foot-lifting apparatus, compared to one not equipped with foot-lifting gear.
Presence of a footbath at the parlor exit or other site on the farm, compared with not having a footbath. (Increased lameness may have been due to improper footbath use on these farms.)
Not providing supplemental vitamins and minerals to lactating cows, compared with supplementing animals.
Feeding corn silage to heifers, compared with not doing so. (Rapid fermentation of corn silage in the rumen may lead to metabolic disorders which reduce hoof-horn development.)
Study results appeared in the May Journal of Dairy Science.
