Research Note: Effect of Feed Restriction on Feed Efficiency and Incidence of Sudden Death Syndrome in Broiler Chickens

Feed 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...

Effect of Qualitative and Quantitative Feed Restriction on Growth Performance and Immune Function in Broiler Chickens*

The current study was conducted to investigate the effect of early feed restriction (FR, 8 to 14 d of age) on growth performance and immune function in broiler chickens. Birds were fed corresponding diets from 3 to 35 d of age, which consisted of three phases: starter (3 to 7 d of age), FR (8 to 14 d of age) and re-alimentation (15 to 35 d of age) phases. During the FR period, each group of bir...

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 ...

Effect of Malic Acid on Growth Performance, Carcass Characteristics, and Feed Efficiency in the Broiler Chickens

This study was performed with growing chicken (1 to 56 d of age) to evaluate the effects of malic acid on broiler chicken performance. Malic acid was added to the water and offered to chicken freely from first to end of experiment with constant concentration. The treatments were zero (as a control), 0.05, 0.10, and 0.15 percent of malic acid which dissolved in water and given to them in waterer...
