Immunization protocols against Cryptosporidium parvum in ovines: protection in suckling lambs

Pharmacokinetics of doramectin in lactating dairy sheep and suckling lambs

Analytica Chimica Acta, 2005
Abstract The aim of the present study was to estimate permeation of doramectin (DOR) into sheep's milk by following its time course in blood plasma and milk. Six Istrian Pramenka sheep in the early lactation period, each having a suckling lamb, were administered DOR in a single subcutaneous dose of 0.2 mg kg −1 body weight.
