Effect of early feed restriction on metabolic programming and compensatory growth in broiler chickens.
The effect of early feed restriction on metabolic programming and compensatory growth was studied in broiler chickens. A total of 480 female 1-d-old broiler birds (Aconred) were randomly allocated to ad libitum and feed-restricted groups, each of which was replicated 6 times with 40 birds per replicate. Broilers were provided commercial diets. Feed-restricted broilers were deprived of feed for ...
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 کاملEffect of compensatory growth on feed intake and feed conversion efficiency of heavyweight steers
Compensatory growth is an integral part ofNew Zealand beef production systems (Nicol and Kitessa, 1997) with restricted winter nutrition followed by good spring and summer feeding enabling a better fit with seasonal pasture production. Purchasers of store cattle (including feedlotters) often prefer animals with a previous history of perturbed growth because they believe they can benefit from hi...
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...
متن کاملEffects of conjugated linoleic acid on growth performance, feed conversion efficiency, and subsequent carcass quality in broiler chickens.
The effect of dietary conjugated linoleic acid isomers (CLA) on growth performance, carcass composition, fatty acid composition of adipose and muscle tissues, and serum lipoproteins was investigated in broiler chickens. A total of 160 (eighty male and eighty female) chickens were allocated to four dietary treatments (0.0, 0.5, 1.0, and 1.5 % CLA) and fed a standard starter diet from 8 to 21 d, ...
