Feed restriction of turkey breeder hens--a review.
Past research on feed restriction methods with turkey breeder hens has involved the feeding of 1) high-fiber or low-energy diets, 2) low dietary protein, 3) limited quantities of feed, 4) rations on a skip-a-day program, 5) distasteful compounds, or 6) combinations of these methods. In general, feed-restricted turkey breeder hens showed a reduction in BW and a delay in sexual maturity at time o...
متن کاملFeed 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 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 کاملInitiating egg production in turkey breeder hens: thyroid hormone involvement.
The role of thyroid hormones in the expression of photosensitivity-photorefractoriness in female turkeys was investigated through the use of an antithyroidal agent, 6-n-propyl-2-thiouracil (PTU). In experiment 1, females held continuously from hatch on long day lengths (16L:8D; LD) and fed 0.1% PTU from 0 to 16 wk, began laying eggs at 26 wk of age, peaking at 75% hen-day egg production by 29 w...
متن کاملEffects of Feed Restriction on Production Performance and Carcass Characteristics of Koekoek Chickens in Ethiopia
This study was conducted to examine the effects of feed restriction on production performance as well as traits relating to egg and carcass yield in Potchefstroom Koekoek dual purpose chicken bred under Ethiopian conditions. A total of 240 one-day-old dual purpose Koekoek chicks were randomly distributed into 12 experimental pens, representing 4 feeding treatments to evaluate the performance of...
