Reduced test-day milk fat percentage in cows diagnosed with claw horn lesions during routine claw trimming.
The objective of this study was to investigate whether cows diagnosed with claw horn lesions during routine claw trimming had an altered milk fat percentage on test days preceding the diagnosis, compared with cows without such lesions. Data included date of trimming, cow number, type, and location of claw lesions recorded by a professional claw trimmer during routine trimming sessions on 11 com...
متن کاملEvaluation of treatments for claw horn lesions in dairy cows in a randomized controlled trial.
Lameness is one of the most significant endemic disease problems facing the dairy industry. Claw horn lesions (principally sole hemorrhage, sole ulcer, and white line disease) are some of the most prevalent conditions. Despite the fact that thousands of animals are treated for these conditions every year, experimental evidence is limited on the most effective treatment protocols. A randomized, ...
متن کاملRecovery of chronically lame dairy cows following treatment for claw horn lesions: a randomised controlled trial.
A positively controlled, randomised controlled trial (RCT) was undertaken to test recovery of cows with claw horn lesions resulting in lameness of greater than two weeks duration. Cows on seven commercial farms were mobility scored fortnightly and selected by lameness severity and chronicity. Study cows all received a therapeutic trim then random allocation of: no further treatment (trim only (...
متن کاملLiver fat content and lipid metabolism in dairy cows during early lactation and during a mid-lactation feed restriction.
During the transition period, the lipid metabolism of dairy cows is markedly affected by energy status. Fatty liver is one of the main health disorders after parturition. The aim of this study was to evaluate the effects of a negative energy balance (NEB) at 2 stages in lactation [NEB at the onset of lactation postpartum (p.p.) and a deliberately induced NEB by feed restriction near 100 d in mi...
متن کاملSYMPOSIUM: ENVIRONMENTAL RISK FACTORS FOR LAMINITIS Environmental Influences On Claw Horn Lesions Associated With Laminitis And Sub-acute Ruminal Acidosis (SARA) In Dairy Cows
A dairy cow’s environment may influence the onset of laminitis and associated claw horn lesions by exacerbating changes in the hoof triggered by events at parturition, onset of subacute ruminal acidosis, or claw horn growth and wear and ground reaction forces on different walking surfaces. Environmental risk factors for laminitis and associated claw horn lesions include feed bunk space and desi...
