Growing pigs were placed on high, medium and low planes of dietary energy and were infected with a virulent strain of Trypanosoma brucei. During an 8-week period post-infection (p.i.), the respective liveweight gains by infected pigs on high, medium and low energy levels were 52.1, 21.2 and 38.5%, respectively, of the corresponding gains by non-infected(More)

Dilution procedures using tritiated water and Evans blue dye (T 1824) were applied to estimate total body water and plasma volume in small ruminants, pigs and cockerels during the two different seasons in Zimbabwe. The amounts of total body water (TBW) obtained were between 60% to 85% of the body weight in sheep and goats, 40% to 60% in pigs and 63% to 75%(More)
Morinda lucida extracts, the stem bark, the root bark and the leaves were screened for antimalarial activity in a "4-day schizontocidal test' against a chloroquine-sensitive strain of P. berghei berghei in mice. Each extract was administered as a single daily dose on days 0, 1, 2 and 3 to mice that had received an intraperitoneal inoculum of 1 X 10(7)(More)
The osmotic fragility of the erythrocytes was measured in blood samples collected from randomly selected healthy and infected dogs at a dogs' rescue shelter. The dogs were classified into six groups on the basis of the final diagnoses from clinical, post mortem and laboratory findings. The minimum (less than 5 per cent) and maximum (more than 90 per cent)(More)
The chemical properties of the African palm weevil, Rhychophorus phoenicis (F.) (Coleoptera: Curculionidae), larvae were evaluated using standard methodology. The chloroform-methanol extract yielded 37.12% on a dry basis. The oil was liquid at room temperature with a flash point of 36.0 °C. Analysis of the physical constants indicated values of 192.25 Wijs(More)
Ten male pigs (Large White x Landrace), 7 months old, were randomly allocated to two experimental groups. Five of them were castrated and the other five served as controls. Sera were collected on the day of castration and 1, 5, 6 and 7 weeks after castration for hormone assay. There was a significant rise in the splenic and pancreatic weights in the(More)
The biochemical and haematological profiles of 379 pigs with or without various gross pathological lesions in an abattoir in Zimbabwe were studied to see whether there were any differences between the levels of haematological and biochemical values, and health status (with and without pathological lesions). On the basis of observable gross pathology, 134(More)
The effect of alpha-trinositol (D-myo-inositol-1,2,6-trisphosphate) on cholera toxin-induced fluid accumulation (i.e., net fluid secretion) was studied in the pig jejunum in vivo. Cholera toxin caused a dose-dependent fluid accumulation in control experiments. Intravenous injection of alpha-trinositol produced a reduction of the response to cholera toxin(More)
