Susceptibilities of 5 different mice strains, including C3H/HeN, BALB/c, C57BL6, FvB and ICR, to Echinostoma hortense infection, was evaluated. The worm expulsion rate, worm size and egg production were observed from 1 to 8 weeks after infection with 30 metacercariae. C3H/HeN and ICR mice showed the highest worm maturation rates. The worm recovery rate and the number of eggs per gram (EPG) of f...

The effect of yeast culture (Saccharomyces cerevisiae) supplementation on laying hen diets was tested against flavomycin supplementation during 12 weeks, using 112 Brown Bovans laying hens, 52 week-old, divided into 7 equal groups fed on a basal diet containing 18.8% crude protein and 2810 kcal/kg ME (metabolizable energy) feed. Three groups were supplemented with 3 different levels of commerci...

Light intensity, spectrum and pattern may affect laying hen behaviors and production performance. However, requirements of these lighting parameters from the hens' standpoint are not fully understood. This study was conducted to investigate hens' needs for light intensity and circadian rhythm using a light tunnel with five identical compartments each at a different fluorescent light intensity o...

Individual-based models have gained popularity in ecology, and enable simultaneous incorporation of spatial explicitness and population dynamic processes to understand spatio-temporal patterns of populations. We introduce an individual-based model for understanding and predicting spatial hen harrier (Circus cyaneus) population dynamics in Great Britain. The model uses a landscape with habitat, ...

W hen Linda agreed to become nurse manager for the floor of a major teaching hospital, she had no illusions that turning around this " war zone, " as she describes it, would be easy. Nurses were using street language in front of patients. Staff members yelled at each other. Patients routinely wrote complaints about the staff. In other words, respect, teamwork, and accountability were scarce. Th...

the objective of this study was to evaluate the effect of cottonseed meal (csm) treated with sodium bentonite (sb) on laying hen profit and apparent digestibility of nutrients. a 3×3 factorial arrangement in a completely randomized design with 9 dietary treatments of 4 replicates consisting 3 levels of sb (0, 1 and 2%) and 3 levels of csm (0, 10 and 20%) were tested. nine mash diets were fed to...
