The Function Of The Oviduct In Relation To Sperm Transport And Capacitation In Swine, Paisan Tienthai Jun 2004

The Function Of The Oviduct In Relation To Sperm Transport And Capacitation In Swine, Paisan Tienthai

The Thai Journal of Veterinary Medicine

In the pig, sperm transport is regulated, to facilitate normal fertilization of the ovulated oocytes, by the oviduct which contains a particular segment, the sperm reservoir. The main function of the sperm reservoir is to ensure that stored spermatozoa have maintained viability and fertilizing capacity. The process of sperm capacitation is delayed in the sperm reservoir, during the lengthy pre-ovulatory estrus by interactions between the spermatozoa, the oviduct epithelium and secretion products. Sperm capacitation seems to be facilitated by the tubal fluid in the upper segment of the oviduct releasing sperm from the reservoir in relation to the time of …

Physiological Reactions Of Poultry To Heat Stress And Methods To Reduce Its Effects On Poultry Production, Narongsak Chaiyabutr Jun 2004

Physiological Reactions Of Poultry To Heat Stress And Methods To Reduce Its Effects On Poultry Production, Narongsak Chaiyabutr

The Thai Journal of Veterinary Medicine

Thermal environment is regarded as the prime factor governing the production because, both the feed consumption and heat production are related closely to the thermal environment. Therefore, heat stress is caused by a combination of environmental and animal factors that result in reduced performance as the animal attempts to cool itself. In this review, the physiological reactions of bodily functions during heat exposure in poultry are described. Thermal panting, the marked response of poultry to heat stress, is compensatory behavior to permit a high rate of evaporative cooling from the respiratory tract. Cardiorespiratory responses to thermal stress show different patterns …

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.
