Although many studies of Drosophila melanogaster report an effect of diet upon lifespan, it is assumed rather than know that adults maintained on restricted diet acquire fewer nutrients. Diet is restricted in practice by feeding flies a medium where nutrients are diluted and some early reports suggest that flies on diluted medium compensate with increased food intake to consume equal calories o...

Juvenile Chinese three-keeled pond turtles (Chinemys reevesii) were subjected to one of four different feeding regimens: ad libitum (AL), restricted (R), ad libitum-restricted (AL-R), or restricted-ad libitum (R-AL) for 13 weeks, to assess the compensatory growth (CG) response to food restriction and subsequent re-alimentation. After switching to ad libitum feeding, the turtles in R-AL group at...

Feed restriction may be a strategy used by farmers to limit digestive disorders after weaning. The objective of this study was to evaluate the effect of feed restriction applied 1 wk after weaning on growth performance and health of pigs reared in 2 different sanitary conditions (Good vs. Poor; managed in opposite ways with respect to cleaning, animal density, and preventive antibiotic use) and...

BACKGROUND: The use of antibiotics as feed additive in animal feeds due to the appearance of residues in milk and meat and their effects on human health has restricted. Two of essential oils with high potential for use in ruminant diet are Mentha piperita (peppermint) and Mentha pulegium (pennyroyal) essential oil. OBJECTIVE: This study was conducted to investigate the effects of essential oils...

OF THESIS CENTRAL AND PERIPHERAL REGULATION OF CIRCADIAN GASTROINTESTINAL RHYTHMS Circadian clocks are responsible for daily rhythms in gastrointestinal function which are vital for normal digestive rhythms and health. The present study examines the roles of the circadian pacemaker, the suprachiasmatic nuclei (SCN), and the sympathetic nervous system in regulation of circadian gastrointestinal ...

Feeding restriction, as a trigger for compensatory growth, might be considered an alternative viable strategy for minimizing waste as well as production costs. The study assessed whether juvenile redclaw crayfish Cherax quadricarinatus (initial weight 0.99 ± 0.03 g) was able to compensate for feeding restriction at different temperatures (23 ± 1, 27 ± 1 and 31 ± 1 ° C). Hyperphagia, food utiliz...
