OBJECTIVE To assess the efficacy of prophylactic hoof health examination and trimming during midlactation at reducing the incidence of lameness during late lactation in dairy cows. DESIGN Randomized field trial. ANIMALS 333 Holstein cows. PROCEDURES Cows without apparent lameness were randomly allocated into 1 of 2 groups approximately 204 days after calving. Cows allocated to the treatme...

Laminitis has been described in many species, but is most common in the equine and bovine. Although bovine laminitis is most common in lactating dairy cows, it has been reported in all ages and sexes. Laminitis is an inflammation of the laminar corium of the hoof wall, and also includes the sole corium in the bovine definition. In general, the term laminitis is used to describe a systemic disea...

Background: Horse hoof abnormalities are one of the most frequent disorders in horses and leading causes affecting productivity horses. Purpose: Explanation percentage Andalusian, Warmblood, Generasi Santosa Stable. Method: Qualitative methods this study used a qualitative research approach case study. Results: Hoof occurred 6 (1 stallion 1 Andalusian mare, Warmblood 2 G4 stallions, G3 horse). ...

UNLABELLED A lightweight bracelet that provides tactile stimulation to the horse's pastern and coronet induces a higher flight arc of the hoof. This study addresses the pattern of habituation to these devices. OBJECTIVE To evaluate short-term habituation to tactile stimulation of the pastern and coronet in trotting horses. METHODS Tactile stimulation was provided by a lightweight (55 g) dev...

A method for culturing explants of lamellar hoof was developed to investigate the process of lamellar separation that occurs in laminitis. Explants, consisting of hoof wall, dermal and epidermal lamellae and the adjacent sub-lamellar connective tissue remained intact when cultured in tissue culture medium for 2 days. However, when cultured in the presence of the matrix metalloproteinase (MMP) a...

Left-right symmetrical distal limb conformation can be an important prerequisite for a successful performance, and it is often hypothesized that asymmetric or uneven feet are important enhancing factors for the development of lameness. On a population level, it has been demonstrated that uneven footed horses are retiring earlier from elite level competition, but the biomechanical consequences a...

Because musculoskeletal injuries to racehorses are common, instrumentation for the study of factors (e.g. track surface), which affect the ground reaction loads in horses during racing conditions, would be useful. The objectives of the work reported by this paper were to (1) design and construct a novel dynamometric horseshoe that is capable of measuring the complete ground reaction loading dur...

Keratin from the hoof is a less explored source for making valuable products. In this paper we present the extraction of pure keratin from bovine hooves and characterized them to better address the possible exploitation of this bio-resource as an alternative material for tissue engineering applications. The keratin protein from the pulverized hooves was extracted by reduction, which was observe...

In the western United States, sugar beet processing for sugar recovery generates a lime-based waste product (∼250,000 Mg yr) that has little liming value in the region's calcareous soils. This area has recently experienced an increase in dairy production, with dairies using copper (Cu)-based hoof baths to prevent hoof diseases. A concern exists regarding soil Cu accumulation because spent hoof ...

BACKGROUND Soundness is important for welfare and utility of the riding horse. Musculoskeletal disorders are the most common causes of interruption in training and of culling. Despite great importance, heritability of a majority of health traits in horses has previously not been estimated. The objective was to perform genetic analyses of medical and orthopaedic health traits in young riding hor...
