Cloacal reflexes and uptake of fluorescein-labeled polystyrene beads in broiler chickens

Localization and (semi-)quantification of fluorescent beads of 2 sizes in chickens over time after simultaneous intratracheal and cloacal administration.

Environmental particles enter the chicken via several routes. Entry via the respiratory and cloacal routes likely activates immune responses. We studied the localization of simultaneous intratracheally and cloacally applied beads of 2 sizes in the chicken body in time, and when possible, semiquantified the amount of beads. Ten broiler hens, 3.5 wk of age, received 1.25 × 10(9) 1.0-µm beads and ...

Ochratoxicosis in Broiler Chickens:

This experiment was conducted to evaluate the effects of ochratoxin A (OTA) on the function and histology of the liver, kidney and bursa of broiler chickens fed OTA contaminated rations. Two hundred forty one-day-old male Ross broiler chicks were used, they were randomly divided into 3 dietary experimental groups of 80 birds and given rations containing 0 (control), 400 or 800 μg OTA/Kg feed. T...

T-2 metabolites in the excreta of broiler chickens administered 3H-labeled T-2 toxin.

A method for the detection of T-2 metabolites was developed and applied to analysis of metabolites in excreta of broiler chickens administered 3H-labeled T-2 toxin. The method used acetonitrile extraction and partitioning with petroleum ether followed by chromatography on Amberlite XAD-2, Florisil, and Sep-Pak C18. The recovery of T-2 toxin added to the chicken excreta was 73% at a concentratio...

use of expanded polystyrene (eps) and shredded waste polystyrene (swap) beads for control of mosquitoes

background: mosquitoes transmit several diseases to human. there are several measures for control of larvae. as part of integrated vector management (ivm) program, the utility of floating layers of polystyrene beads (eps) is a po­ten­tial alternative in habitats of mosquito larva. eps beads prevent oviposition of mosquito as well as killing the im­ma­ture stages by forming a tick layer on the w...
