| The NAHMS Dairy '96 Study was designed to provide both participants and the industry with information on the nation's dairy animal population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid sample yielding 2,542 producers. Included in the study were 20 states that represented 83.1 percent of the U.S. milk cows as of January 1, 1996. Data on digital dermatitis were collected during the second phase as Federal or state Veterinary Medical Officers (VMO's) or Animal Health Technicians (AHT's) contacted producers from February 20 through May 24, 1996 to complete a questionnaire.

| Feet lesions and lameness prevalence were studied in Holstein dairy cows housed in free-stall and tie-stall systems in São Paulo state farms. In the free-stall system, digital dermatitis, flat sole and axial erosion were the prevailing lesions. However, in the tie-stall system the following lesions predominated: sole bleeding, white line disease, heel erosion, double sole, interdigital dermatitis, hoof cracks and long toellow heel. In both management systems a positive correlation was found between feet lesions and the number of parturitions. The cows' age and the number of parturitions in addition to the management system influenced feet lesions in dairy cows.. |

| ABSTRACT: The aim of this study was to confirm the possible consequences of prepartum lameness on subsequent lactation among Holstein cows. In this research, 27 multiparous cows, were monitored from the 30th to 63rd day, relative to calving. Thirty days prior to parturition, the animals were segregated into two groups based on the locomotion score (LS), where LS 1 is attributed to animals without claudication, LS 2 to those with suspected lameness and LS 3, 4 and 5 to those with mild, moderate and severe lameness, respectively; in the lame cows group (LC) (n=15), the animals displayed LS ≥ 3, whereas in the non-lame cows group (NLC) (n=12) they showed LS 1. Milk production, body condition score (BCS) and blood concentration levels of β-hydroxybutyrate... |
