The influence of increased feeding on the susceptibility of sheep to infection with Haemonchus contortus
(1999-10)
Previous research has shown that supplementing the diet of growing lambs with urea enhances their ability to withstand gastrointestinal infection with the nematode Haemonchus contortus. This study compared lambs given two ...
Pharmacokinetics of enrofloxacin and danofloxacin in plasma, inflammatory exudate, and bronchial secretions of calves following subcutaneous administration
(1999-08)
Enrofloxacin (2.5 mg/kg of body weight) and danofloxacin (1.25 mg/kg) were administered subcutaneously to ruminating calves (n = 8) fitted with subcutaneous tissue cages. Concentrations of enrofloxacin, its metabolite ...
The relationship between the number and size of nematodes in the abomasum and the concentration of pepsinogen in ovine plasma
(1999-08)
Six-month-old lambs that had been naturally infected with predominantlyTeladorsagia (Ostertagia) circumcinctawere tested for plasma pepsinogen concentrations because pepsinogen concentrations may reflect the extent of ...
The distribution of pepsinogen within the abomasa of cattle and sheep infected with Ostertagia spp. and sheep infected with Haemonchus contortus
(1999-03-31)
The effect of nematode infections on the production of pepsinogen by ruminants was investigated immunohistochemically and biochemically. Abomasal tissues were collected from parasite-naive cattle and sheep, from sheep ...
Antibiotics and resistance in farm animals
(1999)
Antibiotics are used in animals to cure disease and prevent suffering. Bacterial populations in animals which are exposed to these antibiotics may be selected for resistance. There is a concern that spread of these bacteria ...
