Feed restriction significantly alters lipogenic gene expression in broiler breeder chickens.
Broiler breeder pullets were divided into two groups at 21 wk of age. One group was given free access to feed (ad libitum) and the other fed a limited amount of feed (restricted). At 22 wk, all birds were photostimulated and maintained throughout an egg-laying cycle ending at 36 wk. Samples of liver and abdominal fat pad were collected just before photostimulation (prelight), after photostimula...
متن کاملFeed Restriction in Broiler Chickens Production
The feed restriction program is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken. Quantities and qualitative feed restriction are procedures that can be used to manipulate the feeding strategies of poultry in order to decrease growth and metabolic rate to some extent and so alleviate the incidence of some metabolic diseases such as a...
متن کاملPharmacokinetics of levamisole in broiler breeder chickens.
The pharmacokinetics of levamisole was studied in 20 broiler breeder chickens (chickens that give eggs to breed broilers). A single dose of levamisole (40 mg/kg) was administered orally or intravenously to chickens before the onset of egg production, prelay (age = 22 weeks), and repeated at the peak of egg production (age = 32 weeks). A high-pressure liquid chromatographic with ultraviolet dete...
متن کاملFeed restriction inhibits early follicular development in young broiler-breeder hens
Ad libitum feeding causes excessive follicular development and is associated with extensive metabolic changes in broiler-breeder hens. Restricting feed intake reduces excessive follicular development, but the mechanisms mediating this response are unknown. In the present study, the effects of feeding on follicular development in immature broiler-breeder hens were examined. There was an increase...
متن کاملVariation in feed intake of broiler chickens
With many broiler diets, particularly wheat–based diets, rate of passage of digesta limits intake and growth. In many trials, the relationship between feed intake and apparent metabolizable energy (AME) was negative or insignificant. In some trials, the limitation to voluntary intake was so severe that negative relationships existed between it and FCR. This is a consequence of the diversion of ...
