Genetic parameters for faecal egg count following mixed, natural, predominantly Ostertagia circumcinta infection and relationships with live weight in young lambs
Faecal egg counts and live weights were measured on approximately 200 predominantly twin-born Scottish Blackface lambs each year for 3 years, from 2 to 6 months of age. Measurements were made at 4-week intervals following ...

Interaction between fenbendazole and piperonyl butoxide : pharmacokinetic and pharmacodynamic implications
The effect of the cytochrome P450 inhibitor, piperonyl butoxide on the pharmacokinetics and anthelmintic efficacy of the benzimidazole compound fenbendazole was studied in sheep and goats. Pretreatment of goats with the ...
Comparative pharmacokinetics of paracetamol (acetaminophen) and its sulphate and glucuronide metabolites in desert camels and goats
Paracetamol was administered at dosages of 5 mg/kg to camels and 10 mg/kg to goats by the intravenous and intramuscular routes, Parent paracetamol had a significantly slower clearance (21.9 +/- 1.4 ml/mL . kg vs, 52.8 +/- ...
Pharmacokinetics and tolerance of florfenicol in Equidae
Florfenicol was administered to horses and ponies at a dose rate of 22 mg/kg bwt by i.v., i.m. and oral routes. Following i.v. administration it had an elimination half-life of 1.8 +/- 0.9 h, a body clearance of 0.4 +/- ...
An ovine lymphocyte antigen is associated with reduced faecal egg counts in four-month-old lambs following natural, predominantly Ostertagia circumcincta infection
Ten lymphocyte antigens were defined in a flock of Scottish Blackface sheep known to be naturally exposed to infection with Ostertagia circumcincta. Population and family studies suggested that the 10 antigens were products ...
Influence of soyabean meal supplementation on the resistance of Scottish Blackface lambs to haemonchosis
Protein supplementation improves the resistance of sheep to haemonchosis. This experiment investigated the Scottish blackface breed to establish whether dietary protein supplementation is still beneficial in a genetically ...
