Efficacy of Routinely Used Anticoccidials Against Eimeria tenella Field Isolates in Chicken: Bangladesh Perspective

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
Among five experimental drugs, toltrazuril showed the highest effectiveness, whereas sulphaclozine was found to be resistant among all the isolates against caecal coccidiosis. The outcome recommends toltrazuril against chicken coccidiosis but highly suggests avoiding long‐term use to minimize drug resistance.

Effect of Lasalocid on Performance of Lactating Dairy Cows

Journal of Dairy Science, 1990
Thirty-two midlactation dairy cows were fed either a typical dairy diet or the same diet plus 340 mg lasalocid/d for 98 d. Diets were 65% forage (alfalfa and corn silage) and 35% concentrate (DM basis). Lasalocid did not affect production of milk (21 kg/d) or FCM (20 kg/d) or milk composition.

Maduramicin poisoning in prepartum dairy cows due to cross‐contamination of anionic salts

Veterinary Record Case Reports, Volume 13, Issue 3, September 2025.
Abstract Maduramicin is prohibited in ruminant feed due to its high toxicity. The aim of this study is to describe a case of maduramicin poisoning caused by industrial cross‐contamination of anionic salts in prepartum dairy cattle. The clinical signs observed included anorexia, depression, nasal discharge, salivation, reddish urine and haematochezia ...
