Available online 22 June 2015 During fourmonths in the winter period of 2002–2003, a census of four species of hoofed animals (red deer, sika deer, roe deer, and musk deer) was conducted in the study areas of the Sikhote-Alin Reserve and the surrounding area, including the territory of the planned Reserve Tavayza. The census was conducted on a monthly basis at two sites in the pine and broadlea...
Digital dermatitis is a serious problem in dairy production in many countries. In many settings, it is important to evaluate the digital dermatitis status of individual cows or an entire dairy herd. Such an evaluation has traditionally been done in a hoof trimming chute. An evaluation in the milking parlor can take place without disturbing the cows to a large extent, it can be done using less l...
New-hoof growth is regarded as the most reliable metric for predicting age of newborn ungulates, but variation in estimated age among hoof-growth equations that have been developed may affect estimates of survival in staggered-entry models. We used known-age newborns to evaluate variation in age estimates among existing hoof-growth equations and to determine the consequences of that variation o...
Wounds of the horse’s foot are common, and many are simple and heal without untoward consequences. Unfortunately, others may cause lasting changes in hoof function, and sometimes even be life threatening. The term foot describes the hoof and all structures contained within it. It is part of the appendicular skeleton and as such most of the same elements, i.e. bones, joints, tendons and ligament...
Zinc has been discussed as a feed additive to improve hoof horn quality and skin diseases. Hooves of good quality contain more zinc than hooves of poor quality (1). Because zinc supplementation seems to increase the zinc content of the hoof (1), the bioavailability of different zinc compounds became potentially important. In the present investigation the serum response after oral supplementatio...
A novel keratinolytic actinobacterium, strain WCC-2265(T), was isolated from bovine hoof keratin 'baited' into composting bovine manure from southern Alberta, Canada, and subjected to phenotypic and genotypic characterization. Strain WCC-2265(T) produced well-developed, non-fragmenting and extensively branched hyphae within substrates and aerial hyphae, from which spherical spores possessing sp...
There is little empirical evidence to indicate that dairy cow live weight affects the extent of soil damage at the hoof-soil interface during grazing on poorly drained permanent grassland. In the present study the impact of Holstein-Friesian (HF) dairy cows with a mean (±standard deviation) live weight of 570 (±61) kg were compared with Jersey × Holstein-Friesian (JX) with a mean live weight of...
