This experiment was conducted, during a seven-week period to investigate, the effects of using various levels of garlic cloves and turmeric rhizome powders, on laying hens’ performance, egg quality characteristics and cholesterol content in yolk. Two hundred and sixteen, 27-weeks old Novogen white laying hens were assigned randomly into nine treatments with eight replicates of three birds each....

this experiment carried out to evaluate replacing effects of oyster shell (os) with filter cake (fc) of sugar beet industry on performance and quantity and quality of egg in  laying hens .in this trial the filter cake in two physical forms of powder and pellet in  five levels of 0, 25, 50, 75, and 100% replaced for oyster shell. each treatment had 3 replications. the experiment lasted 3 periods...

background: use of hormone replacement therapy (hrt) may increase the risk of adult-onset asthma in women. various in vitro studies have reported that estradiol stimulates human mast cell lines causing release of allergic mediators which was not observed in estrogen receptor-alpha (er-alpha) knockout mice. thus, estrogen might be a key element in occurrence of asthma. in the present study, we p...

culture filtrates (cf) of two species of the nematophagous fungi, arthrobotrys oligospora and arthrobotrys conoidesat three concentrations (25%, 50% and 100%) of stock, were tested on the mortality of second stage juveniles (j2) and egg hatching rate of meloidogyne incognita and meloidogyne javanica. results showed that the percent juvenile mortality was directly proportional to concentration o...

The present study evaluated the effect of fluconazole on the heart, as well as and the toxic interactions between fluconazole and disopyramide in chick embryos. Chick embryos have been widely used in pharmacologic and toxicologic experiments for evaluating drug action. Fertilized eggs of White Leghorns were incubated and investigated. Fluconazole 0.4 mg/egg, 0.8 mg/egg, 1.2 mg/egg alone or diso...

The present research was aimed to study the effects of different sources of carotenoids and their varying concentrations on the reproductive functions of goldfish. The study was carried out in seven treatments with three replicates at the Bony Fish Hatchery Complex (Rasht, Iran) from December 2011 to May 2012. Experimental diets containing 50, 100, and 150 mg kg-1 astaxanthin and 50, 100, and 1...
