The effect of one-week intensive feed restriction on the carcass characteristics, meat tenderness, cooking loss, and muscle fibre characteristics of growing rabbits was evaluated. Weaned rabbits (35 days) were divided into three groups: rabbits fed ad libitum (ADL), rabbits fed 50 g (R50), and rabbits fed 65 g (R65) of feed per animal per day in days 42-49 of age. Dressing out percentage was lower (-1.3% and -2.3% for R50 and R65, respectively) in restricted rabbits (P ≤ 0.001) but increased with age (P ≤ 0.001). Cooking loss significantly increased in restricted rabbits. A significant interaction between feeding regime...

The pike-perch is among the economically most valuable fish species for both commercial and recreational fishermen. This could be seen as the main reason for its introductions into Western Europe (including France) and Tunisia. Knowledge of the genetic structure of the introduced populations is a prerequisite for their successful long-term management. The present study focuses on the genetic characterization of introduced Tunisian and French pike-perch populations using species-specific microsatellite loci and mitochondrial cytochrome b haplotypes in order to better understand their genetic relationships and to try to trace the origin of the...

Human scent is a complex combination of many chemical substances. Skin is supposed to be one of sources of scent traces. The values of the boiling points of human scent compounds were supposed to be lower than 300°C. The purpose of the study was to determine the temperature at which the human scent is degraded so that a dog would not be able to identify it. In contrast to expectations, eight dogs used in the experiment almost flawlessly identified human scents from five scent donors exposed to temperatures of 100°C, 200°C, 300°C, 400°C, 500°C, 600°C, 700°C, and 800°C. Only two of the dogs were able to identify 5 of 15 scent samples exposed to 900°C....

The effects of dehydroepiandrosterone (DHEA) on lipid metabolism and lipogenic gene mRNA expression in rats subjected to a high-fat diet were determined. Totally 75 rats were randomly divided into 5 groups: control group 1 fed a normal diet (NCG), and groups 2-5 fed a high-fat diet with 0 (HCG), 25 (HLG), 50 (HMG), 100 (HHG) mg DHEA per kg body weight via gavage once a day for 8 weeks, respectively. DHEA significantly decreased body weight in HMG group as compared with HCG group (P < 0.05). Hepatic triglyceride and total cholesterol contents were decreased in HMG and HHG groups (P < 0.05), and hepatic lipase activity in HMG...

The present experiment investigated the effects of conjugated linoleic acid (CLA) on the growth performance, oocyst shedding, duodenal mucosal immune response, and redox status of broiler chicks infected with Eimeria acervulina. Totally 144 birds were fed either the basal diet or 1.5% CLA diet for 21 days, and then half of them from each dietary treatment were inoculated with 10 000 Eimeria acervulina sporulated oocysts. Compared with the basal diet, the 1.5% CLA diet partially ameliorated the growth inhibition (P < 0.01) and decreased the oocyst shedding of broiler chicks at ca. 6-9 days post-inoculation (P <...

The present study was conducted to examine the effects of retinoic acid (RA) on the synthesis of selenoprotein and the antioxidative indices of bovine mammary epithelial cells (BMEC) in vitro and to explore the antioxidative mechanisms of RA in the BMEC. The subconfluenced BMEC were divided into six treatments with six replicates per treatment and cultured in a Dulbecco's Modified Eagle's Medium/F12 media (10% fetal bovine serum, 5 µg/ml ovine prolactin, 10 ng/ml epidermal growth factor, 1 g/ml hydrocortisone, 0.5% insulin-transferrin-selenium) containing different levels of RA (0 (control), 0.05, 0.1, 0.2, 1 or 2 mg/ml) for 24 h. Addition...
