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 کاملEffect of restricted feeding and realimentation on feed performance and carcass characteristics of growing lambs1
Forty Najdi ram lambs weighing 26.6±0.3 kg were utilized in this experiment to determine the effects of feed restriction followed by realimentation and body weight at the onset of feed restriction (30 and 36 kg body weights) on performance and carcass characteristics; feeding and restriction levels were ad libitum, 0.75 and 0.60 of the ad libitum intake. All lambs were slaughtered after 14 week...
متن کاملEffects of restricted feeding of growing steers on performance, carcass characteristics, and composition.
Two experiments were conducted to determine the effects of restricted feeding on performance, carcass characteristics, and composition. In Trial 1, 36 individually penned steer calves (280 +/- 13 kg BW) were fed all-concentrate diets at intake levels of ad libitum and 90 and 80% of ad libitum. Trial 2 used 36 individually penned steer calves (298 +/- 14 kg BW) fed corn silage-based growing diet...
متن کاملFeeding weaned piglets and growing -
In 2000, EU regulations for organic animal production set new guidelines for organic pig feeding requiring that this be based on mainly home-grown organic feedstuffs. Doubts were however raised whether these feeding regimes can maintain good growth performance and carcass quality of pigs. Three experiments were carried out to study different organic feeding regimes in weaned piglets and fatteni...
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...
