Short-Term Exposure of Laying Hens to High Dietary Sodium Chloride Levels

Toxicity of high dietary levels of DDT in laying hens.

White Leghorn hens were fed diets containing 0, 300, 600, or 1200 ppm technical grade DDT for three 28-day periods. The 1200 ppm diet caused tremors and 33% mortality in the final period, but no gross toxicity symptoms were seen in birds fed the other diets. Egg production was decreased during the third period by 600 or 1200 ppm. Egg weight was decreased during the third period by 600 or 1200 p...

Short-term exposure to high levels of natural external gamma radiation does not induce survival adaptive response

Background: In some areas of Ramsar, a city in northern Iran, residents receive a much higher annual radiation exposure than is permitted for radiation workers. Induction of adaptive response in residents of Ramsar has been reported previously. In this study induction of such a response in short term exposure to high background levels of gamma radiation is investigated. Materials and M...

Effects of sodium bicarbonate, potassium chloride and sodium chloride supplementation on some blood biochemical parameters in laying hens

*Corresponding author: [email protected] ___________________________________________________________________________ This research was carried out to determine the effect of supplementation of sodium bicarbonate (% 0.38, % 1.5), potassium chloride (% 0.7) and sodium chloride (% 0.25) at different levels in diets of 480, 25-week old laying hens on blood plasma Ca, Pi, Mg, CI, Na, K, total ...
