The Thai Journal of Veterinary Medicine

Trifluralin, a herbicide, was observed for it's side effects when used, extralabel, as an ectoparasiticide in shrimp farming. Black tiger shrimp were exposed to trifluralin at a therapeutic level, commonly employed in shrimp farming, 0.1 or 0.2 ppm, for up to 96 hrs. Shrimp were examined 96 hrs after the primary dosage of trifluralin. The total haemocyte count in the exposed shrimp was not different from the control, unexposed shrimp. A significant reduction of muscle acetylcholinesterase was found in all exposed shrimp (p<0.05). Some of the exposed shrimp also demonstrated clinical signs of cholinergic overload characterized as abnormal movement. This study suggests sublethal effects when trifluralin is used for the treatment of shrimp ectoparasitic disease.

First Identification Of Neospora Caninum In Thailand, Than Kyaw, Prachin Virakul, Manop Muangyai, Wijit Banlunara

The Thai Journal of Veterinary Medicine

An immunohistochemical examination of aborted bovine tissues, collected from two dairy farms that had a high abortion rate (7%), detected the organism Neospora caninum (NC). Five out of 12 aborting cows (41.7%) were seropositive to NC using a competitive ELISA test. Neospora-tachyzoites were detected in the placenta of a seropositive aborting cow. Neither NC parasites nor cysts were detected in other fetal tissues. The identification of the Neospora-parasite and a high percentage of Neospora seropositive aborting cows, suggested NC as the possible cause of abortion. This is the first identification of the NC parasite in Thailand.

Exercise And Dehydration In The Horse, Prawit Butudom Dec 2003

Exercise And Dehydration In The Horse, Prawit Butudom

The Thai Journal of Veterinary Medicine

The intensity and duration of exercise has a major impact on fluid levels, electrolytes and acid-base balance in the horse. The changes range from rapid fluid and electrolyte shifts which accompany high-intensity exercise (VO2 max ≥ 100%) (i.e., racehorse) to substantial fluid and electrolyte depletion during Speed and Endurance Tests as seen at Three-day events. Depletion is also seen during prolonged endurance exercise, in which the horse performs a low-intensity form of exercise (30-60% VO2max). These fluctuations of fluid and electrolyte homeostasis have been implicated in the development of fatigue and can lead to medical problems when exercise is continued …
