The effects of feeding meals, in amounts equivalent to ad lib, intake or to 75% and 50% restriction by intubation, were studied in chicks. Growth estimated by body-weight gain and shank length was improved by tube feeding in the 50%-restricted chicks. Tube feeding increased energy retention at all feeding levels and nitrogen retention in the restricted chicks only. Body fat was increased in the...

The mammalian circadian system is composed of multiple peripheral clocks that are synchronized by a central pacemaker in the suprachiasmatic nuclei of the hypothalamus. This system keeps track of the external world rhythms through entrainment by various time cues, such as the light-dark cycle and the feeding schedule. Alterations of photoperiod and meal time modulate the phase coupling between ...

The gut microbiome and daily feeding/fasting cycle influence host metabolism and contribute to obesity and metabolic diseases. However, fundamental characteristics of this relationship between the feeding/fasting cycle and the gut microbiome are unknown. Our studies show that the gut microbiome is highly dynamic, exhibiting daily cyclical fluctuations in composition. Diet-induced obesity dampen...

Milk samples were taken from rats feeding ten pups and from both the suckled and non-suckled glands of rats feeding two pups. The lipid, protein and lactose concentrations were similar in the milks from the secreting glands, but the fluid from the non-suckled glands contained less lactose and lipid but significantly higher total protein and transferrin concentrations. The fatty acid composition...

To investigate the effects of feeding restricted on growth, carcass characteristics and plasma profiles in an attempt for optimum responses, a total of 108 cross-bred finishing barrows [(Landrace×Yorkshire)×Duroc]weighing an average of 46.88±0.52 kg were assigned in a randomized complete block (RCB) design to one of four treatments with three replicates and nine pigs per pen. Feeding regimens w...

forty-two weaned lori-bakhtiari lambs were taken in an investigation for the effects of two-nutritional management methods of restricted vs. re-alimentation feeding on intake, growth and as well on the cost benefit analysis. during the feed restriction period (frp), the control (c) animals were fed low-quality roughage ad libitum, plus mixed concentrate. the restricted animals (r) were fed only...
