Strategic use of anthelmintics for parasitic nematodes in cattle and sheep
(1988-11)
Treatment regimes for the control of parasitic nematodes in cattle and sheep are reviewed. The advantages and disadvantages of each strategy are outlined and the veterinarian's judgement of the management and economic ...
The pharmacodynamics of ivermectin in sheep and cattle
(1988-09)
The concentrations of ivermectin in the gastrointestinal tract of sheep and cattle were determined after subcutaneous administration of ivermectin. Ivermectin was not detected (limit of detection 1 ng/ml) in abomasal and ...
Production of strains of the sheep parasite Ostertagia circumcincta by implantation of adult parasites into the abomasum of lambs
(1988-07)
The implantation of a single pair of adult parasites of Ostertagia circumcincta via the abomasa of four lambs resulted in the production of 19, 53, 393 and 425 viable larvae after faecal culture using faeces collected from ...
Efficacy of ivermectin against Cooperia curticei infection in sheep
(1988)
Lambs were inoculated with a single dose of Cooperia curticei. Subcutaneous administration of ivermectin at a dosage of 200 micrograms/kg of body weight resulted in 61.1% and 90.4% anthelmintic efficacy, when measured at ...
Forms of bovine pepsinogen in plasma from cattle with three different 'syndromes' of Ostertagia ostertagi infection
(1988-01)
Calves infected orally with third stage larvae of Ostertagia ostertagi or infected with adult O ostertagi by direct transplantation into the abomasum had raised plasma pepsinogen activity, as did four-year-old dairy cattle ...
Comparison of ivermectin, oxfendazole and levamisole for use as anthelmintics during the periparturient period in sheep
(1988)
Ewes synchronised with progestin impregnated sponges to reduce the spread of lambing were treated during the periparturient period with anthelmintic. The suppression of nematode egg output in faeces was measured in ewes ...
Multiple forms of bovine pepsinogen : isolation and identification in serum from calves with ostertagiasis
(1987-11)
By using fast protein liquid chromatography (FPLC) a new form of bovine pepsinogen has been identified. Compared with the previously isolated pepsinogen (PG I) the new pepsinogen (PG II) is less mobile on agarose ...
Penicillin therapy of spontaneous streptococcal meningitis in pigs
(1987-10)
Oral prophylactic medication with either procaine penicillin G or a mixture of chlortetracycline, sulphadimidine and procaine penicillin G reduced the incidence of streptococcal meningitis in a herd of pigs with a high ...
Effect of sodium cromoglycate on the response to Ostertagia circumcincta in adult sheep
(1987-09)
Serum pepsinogen concentrations rose more rapidly and to higher levels in adult sheep infected with Ostertagia circumcincta and treated orally with the mast cell stabilising agent sodium cromoglycate than they did in adult ...
