We studied the efficacy of water-soluble extracts from four Ajuga spp on the post-embryonic development of two exopterygota (sucking insect) species. To allow comparison between different Ajuga species, results are expressed in terms of quantity of plant extracted per litre of test solution. Crude methanolic extracts of all Ajuga plants tested, with the exception of A genevensis, showed conside...

The scope of this study was to determine the eff ect of gemfibrozil, l-carnitine and their combination on paraoxonase/arylesterase activity, oxidative/ anti-oxidative parameters and hepatosteatosis in rabbits on fat-rich diet. The study involved 35 New Zealand albino white rabbits. Animals were equally divided into 5 groups (n=7); group I: control (standard diet), group II: rabbits received onl...

This experiment had been done to evaluate the effects of different levels of essential oils (EOs) of wormwood (Artemisia absinthium) and cumin (Cuminum cyminum)on growth performance, carcass characteristics and immune system in broiler chicks. Three hundred ninety two Ross 308 male broiler chicks in a completely randomized design were divided into 7 experimental treatments. The experimental tre...

Two experiments were conducted to evaluate the effects of fusaric acid (FA) in broiler chicks (Exp. 1) and turkey poults (Exp. 2). In each experiment, 100 day-old birds were allotted randomly to dietary treatments containing 0, 100, 200, 300, or 400 mg FA/kg of feed. Each dietary treatment was fed to 4 pen replicates of 5 birds each for 21 days. Fusaric acid had no effect (P > 0.05) on feed int...

This experiment was conducted to determine the influences of supplementing different levels of an additive containing lutein in the diet of Chinese Holstein lactating cows on production performance, antioxidative plasma metabolites, and milk quality. This study was performed on 60 multiparous Holstein dairy cows in peak lactation. The cows were randomly allocated to 1 of 4 homogeneous treatment...

In order to study the effects of a small difference in starch and nitrogen availability on proteolysis, two different diets were supplied to four ewes fitted with rumen fistulae. They differed in the ratio of fermentable nitrogen over fermentable energy. with 144 g of fermentable nitrogen (FN) per kg of fermentable energy (FE) for diet I and 126 g FN x kg(-1) FE for diet II. The diets were cons...

We read with interest the article by Polonsky et al. (1) reporting that self-monitoring of blood glucose (SMBG) improves glycemic control in noninsulin-treated type 2 diabetes. In the U.K., SMBG is recommended for insulin-treated diabetes (2), and controversy exists in relation to treatment with lifestyle advice or oral hypoglycemic agents (OHAs). A Cochrane review concluded that there is insuf...
