Fundamental Aspects of Restricted Feeding of Growing Pullets on Performance in Lay
The paucity of information on reasons for the increased efficiency of egg production by pullets which have been restricted-fed during rearing is discussed. Preliminary results are presented which form part of a detailed research programme aimed at elucidating the mechanisms responsible. Production responses of hens which had been restricted fed during rearing were similar to those expected. Egg...
متن کاملMilk composition of rats feeding restricted litters.
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...
متن کاملAiidrojjen Inhibition of Atherogenesis in Pullets
THE higher incidence of coronary atherosclerosis in young male as compared with young female humans is well established as are similar sex differences in susceptibility in some other species. The administration of female sex hormones to cholesterol-fed cockerels has been reported to have beneficial prophylactic as well as therapeutic effects on coronary atherosclerosis. In one study reported by...
متن کاملMetabolic adaptations of liver mitochondria during restricted feeding schedules.
Food anticipatory activity (FAA) is an output of the food-entrained oscillator (FEO), a conspicuous biological clock that expresses when experimental animals are under a restricted food schedule (RFS). We have shown that the liver is entrained by RFS and exhibits an anticipatory response before meal time in its oxidative and energetic state. The present study was designed to determine the mitoc...
متن کاملAblation of AgRP neurons impairs adaption to restricted feeding
While the SCN controls the circadian clock, further evidence suggests the existence of a food-entrainable oscillator (FEO) that links behavior to changes in food availability such as during restricted feeding (RF). We found that the activity of AgRP/NPY neurons changed rhythmically during RF suggesting that these neurons are a component of the FEO. We next ablated AgRP/NPY neurons in neonates w...
