Field efficacy of two netobimin oral suspensions (5% and 15%) in sheep naturally infected with Dicrocoelium dendriticum

This studywas carried out to compare the efficacy of two suspensions (5% and 15%) of netobimin against Dicrocoelium dendriticum in naturally infected sheep. Fifteen Merino sheep, 4 to 7 years old, were used in this survey. Animals were divided into three equal groups each of five sheep on the basis of bodyweights and D. dendriticum egg counts in per gram faeces. Group A and group B sheep were treated orally with 5% and 15% suspension of netobimin, respectively; both at a dose rate of 20mgkg−1. Group C sheep were left untreated as controls. Twenty-one days post-treatment all sheep were slaughtered for post-mortem examination. All D. dendriticum from the liver and gall bladderwere recovered and counted. The results showed that the efficacy of 5% and 15% suspension of netobiminwas 90.80% and 91.50%, respectively, and the use of 15% suspension in sheep is discussed.
