Hereditary laminitis in Jersey calves in Zimbabwe

Congenital cerebellar hypoplasia in jersey calves.

Congenital cerebellar hypoplasia and hydrocephalus is reported in 8 Jersey calves. The possible relationship between this entity and BVDMD virus is discussed.

A Proposed Selection Index for Jersey Cattle in Zimbabwe

A multitrait selection index (I T ) for Zimbabwean Jersey cattle was constructed. The breeding objective was defined in terms of production and functionality traits. The production component of the index included milk yield (M), butterfat yield (F), protein yield (P), butterfat percent (F%), and protein percent (P%), while the functional component included the somatic cell count (SCC). The inde...

Estimation of plasma volume in Holstein and Jersey calves.

The concentration of immunoglobulin (Ig) G in the blood of neonatal calves shortly after birth is a widely used criterion to determine the degree of acquisition of passive immunity. Another method used to determine the biological mechanisms of IgG absorption is calculation of the apparent efficiency of IgG absorption. Estimation of the efficiency of IgG absorption requires the estimation of pla...

Endocrinopathic Laminitis, Obesity-Associated Laminitis, and Pasture-Associated Laminitis

In a recent online survey, we asked equine practitioners to list the three most common causes of laminitis in horses seen within their practice. We expected veterinarians to list colitis, colic, and retained placenta as the primary causes of laminitis, but many respondents listed obesity, insulin resistance (IR), equine metabolic syndrome (EMS), pituitary pars intermedia dysfunction (PPID), and...
