The current study was aimed at evaluating the effect of heat stress (during the hot-dry period) on some physiological variables, haematology and erythrocyte osmotic fragility (EOF) in bucks, pregnant (single and twin) and lactating Red Sokoto (RS) goats. Forty apparently healthy adult goats were used for the study and were allotted to four groups [bucks (n(More)
The aim of the present study was to evaluate the effect of vitamin C on reproductive toxicity, induced by chronic chlorpyrifos (CPF) exposure in male Wistar rats. Twenty adult male Wistar rats were divided into 4 groups of 5 animals in each group. Group I received soya oil (2 ml/kg); group II was given vitamin C only (100 mg/kg); group III was administered(More)
The present study examined the changes in the fragility of camel and donkey erythrocytes caused by variations in temperature, pH and blood storage. Although the fragility did not differ between sexes in both species, camel erythrocytes were more osmotically resistant than donkey erythrocytes. At a constant pH of 7.4, the fragility decreased in the camel but(More)
The study was carried out to determine the effect of seasonal changes and oestrous cycle phase on serum progesterone (P4) and thyroxine (T4) profiles in Savanna Brown (SB) goats. Ten (n = 10) cycling SB goats with mean body weight and body mass index of 20.17 ± 0.2 kg and 6.2 ± 0.4, respectively were allotted to 2 groups of 5 animals each per season of(More)
This study was carried out to determine heart rate (HR) values, including diurnal, seasonal, and sex patterns, in the African giant rat (Cricetomys gambianus, Waterhouse). HR was measured using stethoscope in grip-restrained African giant rats of either sex (103 bucks and 98 does), live-trapped from a tropical Savannah, and caged individually in the(More)
Chlorpyrifos is a widely used organophosphate insecticide for domestic, agricultural and industrial purposes. Lead is a toxic heavy metal and it is used for domestic and industrial purposes. Taurine is a semi essential amino acid with bioprotective properties. The aim of this study was to investigate the effects of taurine on thyroid function in Wistar rats(More)
The study investigated concomitant effect of gestation and high ambient temperature under a tropical environment on rectal temperature (RT), respiratory rate (RR) and heart rate (HR) responses in Yankasa ewes. Twenty Yankasa ewes, consisting of ten pregnant and ten non-pregnant ewes, were used for the study. Ewes were synchronised and bred, such that each(More)
Haematological parameters and erythrocyte osmotic fragility (EOF) are commonly used as indicators of health status and erythrocyte membrane integrity. Variations in haematological parameters and EOF in late gestation and early lactation during the cold-dry (CDS), hot-dry (HDS) and rainy (RAS) seasons were studied in sixty (n = 60) Red Sokoto goats (20 goats(More)
