This study was conducted to evaluate the effect of feed restriction on some biochemical parameters-related to growth in white Pekin duck. Therefore, fifty white Pekin ducks were allocated into two equal groups as ad libitum and feed restriction group, in which each one was arranged in five replicates. The birds were allowed to free feed access from 1 to 7 days and from 15 to 49 days of age and ...

Feed restriction strategies are proven to be effective in increasing the growth performance and carcass parameters of broiler chickens. The objective of the present experiment was to evaluate the effects of feedremoval for three hour time periodon growth performance and carcass parameters of relatively older male broiler chickens. Twenty days old male broiler chickens (n=80) were allocated into...

Leptin, a protein hormone secreted by adipocytes, plays an important role in energy homeostasis and regulation of body composition. We previously observed that acute feed restriction resulted in a rapid decline in concentrations of leptin in obese pony mares. This acute response prompted us to characterize the temporal changes in concentrations of leptin, GH, and insulin in obese pony mares dur...

Small size at birth has been associated with an increased risk of central obesity and reduced lean body mass in adult life. This study investigated the time of onset of prenatally induced obesity, which occurs after maternal feed restriction, in the guinea pig, a species that, like the human, develops substantial adipose tissue stores before birth. We examined the effect of maternal feed restri...

The effect of the timing of posthatch feed restriction on adipose deposition and adipogenic gene expression in the broiler pectoralis major muscle was studied by applying a 20% feed restriction either the first or second week after hatch. Broiler chicks at hatch were divided into a full-fed (control) group and a 20% feed restriction group. The expression of adipogenic genes, peroxisome prolifer...
