Sera from cattle of the Accra Plains in Ghana were screened for bovine type-4 herpesvirus (BHV-4) antibodies by an indirect immunofluorescence test. Among the 176 screened serums, 14% were found positive at a 1/100 dilution. Further studies are necessary for a better understanding of the relationships between BHV-4 or some other agents and necrotic vaginitis associated with poor fertility observed in cattle in this area.

The variability of the post-exercise values (PEV) of blood lactate and of some other blood constituents were studied in 8 healthy and fit jumpers through 5 national competitions of equal difficulty. The effects of factors such as the individual, performance and competition on these PEV were analysed. Venous blood was sampled immediately after the 5 show-jumping contests and was analysed for packed cell volume (PCV), blood lactate, blood glucose (GLU), total plasma protein (TPP), bicarbonate (HCO3-), sodium (Na+), potassium (K+), chloride (Cl-), calcium (Ca2+), serum activities of lactate dehydrogenase (LDH), creatine phosphokinase (CPK), glutamic-oxalacetic transminase (GOT) and gamma glutamyl transferase (gamma GT). PEV of these 13 blood parameters were analysed using a fixed linear model which included the effect of horse, score and competition and their respective interactions. The analysis of the influence of each of the 3 fixed variables showed that (1) there was no relationship between the PEV variations and the score; (2) there were significant (P less than 0.05) variations induced by the competition in Na+, Ca2+, TPP, LDH and GLU, and (3) there were significant interindividual variations as regards Ca2+, TPP, CPK, gamma GT and PCV with P less than 0.05, LDH with P less than 0.01 and blood lactate with P less than 0.001.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

An ornithine solution, corresonding to 36.1 g ornithine/d, or an equivalent blank solution were each continuously infused into the duodenum of two lactating cows of the Friesian breed. The cows were fed either on a high energy and high protein diet (110% of energy and protein requirements) or a low energy and low protein diet (75% of requirements). Milk composition and milk yield were recorded, and blood plasma contents of amino acids, glucose, growth hormone (GH) and insulin were analysed. The procedure was repeated 1 year later. Ornithine had no effect on milk yields or blood components when thehigh energy and high protein diets were given. On the contrary, it significantly increased milk, lactose, and fat production with the low energy and low protein diets, while milk protein secretion was slightly affected. The levels of nonessential and essential amino acids in blood plasma were enhanced, except for histidine and methionine. The latter amino acids likely were limiting for milk protein synthesis. An increase in glucose supply in the underfed animals likely occured after ornithine administration, since there was a significant increase of plasma glucose and protein levels and total lactose production. Ornithine infusion increased the GH secretion only when the low energy and low protein diets were given. It was concluded that infusion of the non-casein amino acid ornithine into the duodenum increases milk secretion in underfed cows, and that GH likely is involved in this phenomen. [less ▲]
