Vasoactive intestinal polypeptide inhibits electromyographic activity of the reticulo-omasal orifice in meal-fed sheep in warm and cold environments
(1995-09)
The effects of intragastric arterial infusions (1 mL min−1) of physiological saline, vasoactive intestinal polypeptide (VIP) or VIP-antagonist [4Cl-D-Phe6, Leu17] VIP (1 nmol mL−1) on electromyographic (EMG) activities of ...
Anthelmintic resistance amongst sheep and goats in Kenya
(University of Nairobi., 1996)
Faecal egg count reduction tests (FECRT) and larval cultures were used to assess the prevalence of anthelmintic resistance amongst sheep and goats on farms served by Kenya's five regional Veterinary Investigation Laboratories. ...
Renal excretion of urea and electrolytes in sheep and red deer.
(1969-11)
1. The effects of varying the intake of water and nitrogen on the renal excretion of urea and electrolytes has been studied in sheep and in red deer.2. The concentration of urea in the urine of both sheep and deer decreased ...
Feeding practices and effects of gastrointestinal parasite infections on live weight gain of small ruminants in smallholder mixed farms in Kenya
(2008-04)
The objective of this study was to quantify the effects of gastrointestinal nematodosis on live weight gain (LWG) of sheep and goats kept in smallholder farms in Kenya. A total of 307 sheep and goats from smallholder farms ...
Susceptibility to IVM in a field strain of Haemonchus contortus subjected to four treatments in a closed sheep–goat flock in Kenya
(2003)
Susceptibility to IVM (IVM) of “strain A” Haemonchus contortus which had been exposed to IVM four times over a 2-year period was compared to IVM susceptibility of “strain C” H. contortus which had no prior field exposure ...
Strategic control of gastrointestinal nematodes of sheep in the highlands of central Kenya
(University of Nairobi, 2002)
The effectiveness of anthelmintic treatments given 3 weeks after the onset of rains to control gastrointestinal
nematodes in sheep in the highlands of central Kenya was investigated. The study was
carried out on a farm ...
Suspected sheep-associated malignant catarrhal fever in a zero-grazed dairy herd in Kenya
(2000)
An outbreak of a disease characterised by very high mortality occurred in a group of nine calves (1-4 months old) in a zero-grazing unit 2-3 weeks after an introduction of an apparently healthy alien sheep into the calf ...
Anthelmintic resistance in nematode parasites of sheep in Denmark
(University of Nairobi., 1997)
The occurrence of anthelmintic resistance on sixteen sheep farms in Denmark was investigated using the faecal egg count reduction test (FECRT), the egg hatch assay (EHA) for thiabendazole (TBZ) and a microlarval development ...
Increasing accuracy in estimation of economic values for resistance to gastrointestinal helminths in meat sheep
(2010-03)
The impact of utilising different indices and numbers of index traits in estimation of economic values (EVs) for resistance to gastrointestinal (GI) helminths were investigated. Seven indices based on yearling weight (YW), ...
