Rumen protozoa in South African sheep with a summary of the worldwide distribution of sheep protozoa.
Protozoa species were identified in rumen contents of four domestic sheep (Ovis aries) from South Africa. All animals were fed a forage diet which consisted of 50% lucerne and 50% teff hay. Ten new host records were identified, bringing the total number of species and forms observed in sheep in South Africa to 30. The occurrence and geographic distribution of ciliate protozoa in both domest...

متن کاملEffect of Monensin on Ciliate Protozoa in Rumen of Sheep Fed an Oaten Chaff Diet
Field studies of grazing lambs without protozoa in the rumen indicated that live weight gains were 15% higher than in faunated lambs (Bird &nd Leng 1985). Poos et al. (1979) reported that monensin decreased protozoa1 populations in the rumen but Leng et al. (1984) found no effect of monensin on half life or growth rate of protozoa. However in previous studies (Habib, G. & Preston, T.R. 1984 unp...
متن کاملEffect of protozoa on rumen protein degradation in sheep.
We have studied the contribution of ciliate protozoa to the degradation of dietary protein, utilizing 5 defaunated and 6 faunated sheep. Rumen samples from these animals were used as inocular for in vitro determination of the degradability of different protein sources: lupine grain, peanut and soybean cake, and fish meal. We also applied the in sacco method to measure the digestibility of soybe...
متن کاملEpidemiology of gastrointestinal helminths infections in Dorper sheep in a semi-arid area of Kenya.
A survey on the prevalence and intensity of infection with gastrointestinal helminths of Dorper sheep in relation to age and weather factors was carried out on a ranch in Kajiado district, a semi-arid area of Kenya for a period of 13 months (May 1999 to May 2000). Faecal samples from lambs (3 months to 1 year), yearlings (1-2 years) and adult breeding ewes (2-4 years) were examined for helminth...
