Abstract

The objective of this study was to assess both independent and combined effects of routine foot trimming of heifers at 3 weeks pre-calving and 100 days post calving on the first lactation lameness and lactation productivity. A total of 419 pre-calving dairy heifers were recruited from one heifer rearing operation over a 10-month period. Heifers were randomly allocated into one of four foot trimming regimens;pre-calving foot trim and post-calving lameness score (Group TL), pre-calving lameness score and postcalvingfoot trim (Group LT), pre-calving foot trim and post-calving foot trim (Group TT), and precalving lameness score and post-calving lameness score (Group LL, control group). All heifers were scoredfor lameness at 24 biweekly time points for 1 year following calving, and first lactation milk production data were collected.Following calving, 172/419 (41.1%) of heifers became lame during the study (period prevalence), withlameness prevalence at each time-point following calving ranging from 48/392 (12.2%) at 29–42 dayspost-calving to 4/379 (1.1%) between 295 and 383 days after calving. The effects of the four treatmentgroups were not significantly different from each other for overall lameness period prevalence, biweeklylameness point prevalence, time to first lameness event, type of foot lesion identified at dry off clawtrimming, or the 4% fat corrected 305-day milk yield. However, increased odds lameness was significantlyassociated with a pre-calving trim alone (P = 0.044) compared to the reference group LL. The oddsof heifer lameness were highest between 0 and 6 weeks post-partum, and heifer farm destination wassignificantly associated with lameness (OR 2.24), suggesting that even at high standard facilities, environmentand management systems have more effect on heifer foot health than trimming.© 2017 Elsevier Ltd.
