This study compares the prevalence of ixodid tick species on cattle and goats in Maputo Province. Adult ticks as well as the nymphs of three species, and only the adults of two species were collected from sets of five cattle at 21 localities throughout the province and compared with those collected from similar sets of goats at the same places. Amblyomma hebraeum adults and/or nymphs were prese...

Hematological and biochemical parameters were determined in 82 West African Dwarf goats with foreign body rumen impaction (FBR) and 40 normal WAD goats without foreign body rumen impaction (WFBR) in order to evaluate their influence on the etio-pathogenesis of rumen impaction. The mean PCV (26.22%), RBC (9.03 X 106/µL), Hb (8.38g/dl) and MCHC (32.20g/dl) were significantly lower in FBR than in ...

A serological survey in Mozambique to detect antibodies to Cowdria ruminantium, the etiologic agent of heartwater, revealed a seroprevalence of 8.1% (n = 332) for goats in the northern province of Tete and of 65.6% (n = 326) for goats in the southern provinces. Translocation of 10 serologically negative goats from Tete to farms in the south resulted in two clinical cases of heartwater that were...

A survey incorporating field and abattoir studies was carried out on the prevalence of Dicrocoelium dendriticum in sheep and goats in the Kangra valley of Himachal Pradesh (India). Coprological studies on these migratory animals revealed that 8.1% of sheep and 4.1% of goats were positive for dicrocoeliosis, with a mean number of eggs per gram of faeces (EPG) of 702.1 for sheep and 566.7 for goa...

A study of amoxicillin pharmacokinetics was conducted in healthy goats and goats with chronic lead intoxication. The intoxicated goats had increased serum concentrations of liver enzymes (alanine aminotransferase and γ-glutamyl transferase), blood urea nitrogen, and reactivated δ-aminolevulinic acid dehydratase compared to the controls. Following intravenous amoxicillin (10 mg/kg bw) in control...

The aim of this study was to assess the mechanisms of transmission of bluetongue virus serotype 26 (BTV-26) in goats. A previous study, which investigated the pathogenicity and infection kinetics of BTV-26 in goats, unexpectedly revealed that one control goat may have been infected through a direct contact transmission route. To investigate the transmission mechanisms of BTV-26 in more detail a...

Previously we showed that the primer pheromone responsible for the "male effect" was produced in specific skin regions of castrated male goats by androgen treatments. In the present study, we examined whether androgen can also induce production of the male effect pheromone in female goats. Capsules containing dihydrotestosterone (DHT) or testosterone (T) were subcutaneously implanted into six o...

The effect of fetal number (single or twin) on plasma concentrations of progesterone, estradiol 17β, cortisol, prolactin, growth hormone, triiodothyronine, thyroxine and insulin around parturition (periparturient period) were studied on ten Alpine × Beetle crossbred goats in their first to third lactation. The hormone profiles were studied on days -20, -15, -10, -5, -4, -3, -2, -1 prior to kidd...

This study was carried out from November 2007 to March 2008 to identify the species and to determine the burden of small intestinal helminth parasites of sheep and goats slaughtered in Hawassa, southern Ethiopia. Intestines of 116 sheep and 71 goats were examined using standard procedures. Three species of parasites namely Trichostrongylus colubriformis, Bunostomum trigonocephalum and Moniezia ...

Goats’ milk adulteration with cows’ milk is becoming a big problem. In the past, the urea-polyacrylamide gel electrophoresis assay with different motility of αS1-casein has been applied for the identification of cows’ milk adulteration. The detection sensitivity is 1.0%. The aim of this study was to develop a faster and more sensitive method to detect cows’ milk which may be present in adultera...
