I. Reduced intake of energy or protein per se decreased riboflavin requirement of the chicks under restricted feeding regimens. 2. In severe riboflavin deficiency (2.26 mg/kg diet), efficiency of utilization of both energy and protein was decreased significantly under ad lib. conditions of feeding. 3. Efficiency of utilization of energy (but not protein) was decreased significantly in borderlin...

OBJECTIVE To evaluate the effects of physical training of mother rats during pregnancy associated with a low-protein diet offered during pregnancy and lactation on the development and growth of the femur of their offspring. METHODS Forty 90-day old male Wistar rats were divided into four groups: pups of sedentary nourished mothers, pups of sedentary malnourished mothers, pups of trained nouri...

Several dietary alternatives to feed withdrawal have been proposed to induce a molt in laying hens. This study compared the behavior of laying hens on an alfalfa crumble diet (ALC) to hens that were either on a conventional layer diet (FF) or hens that had feed withdrawn (FW) during a 9-d trial. Each treatment consisted of 24 hens (3 hens per battery cage), and treatment began after a 2-week ac...

A total of 108 day-old chicks of hilly chicken were randomly allocated to either pellet form of high protein-energy diet (PHPE) or mash form of low protein-energy diet (MLPE) dietary group having 3 replications in each group. Birds were reared in cages and studied upto 10 weeks of age to compare their growth, feed efficiency and meat production under two feeding regimens. Six birds from each fe...

Studies on rats maintained on low-protein-calorie diets during the lactation period show that food intake decreases. This process results in weight loss and a delay in litter development. The purpose of the present study was to determine the alterations in food intake, maternal weight and litter growth during lactation when dams were exposed to diets with different levels of protein and carbohy...

Two experiments were conducted to evaluate the effect of moderate feed restriction on productivity of lambs classified on the basis of phenotypic expression of residual feed intake (RFI). In Exp. 1, 58 fat-tailed Kurdi ram lambs (32.1 ± 4.2 kg BW) were individually fed, ad libitum, a pelleted diet (35% alfalfa hay and 65% concentrate). Feed intake and ADG were determined for a 6-wk period and 3...

The growth and development of pigs is determined by their genotype environmental conditions (primarily the level feeding), however, number works aimed at studying complex influence genetic non-genetic factors in interaction currently insufficient. purpose our work was to estimate effect MC4R genotype, feeding these on backfat thickness crossbred investigate possibility correcting melanocortin-4...

The master circadian clock located in the suprachiasmatic nuclei (SCN) is dominantly entrained by external light/dark cycle to run with a period of a solar day, that is, 24 h, and synchronizes various peripheral clocks located in the body's cells and tissues accordingly. A daily restricted normocaloric feeding regime synchronizes the peripheral clocks but has no effect on SCN rhythmicity. The a...

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...
