Feed Restriction on Productive Performance of Layer Chickens: A Review

Feed restriction is method of feeding where time, duration and amount of feed are limited, and it has an impact on whether a bird is capable of achieving the same productive performance as unrestricted birds. Feed restriction included of quantitative and qualitative restriction that is in quantitative to limiting the amount of feed daily given to the animals whereas a qualitative restriction is related to nutrient dilution in the diet. Different research results indicated that restriction of feed on layers production have controversial effect on feed intake, feed conversion efficiency, body weight gain, egg weight and quality. Overall, the potential of feed restriction programs as a management’s tool is important to increasing the egg production, egg quality, reduce maintenance requirements and improvement of feed efficiency in layers chickens. Also can be lead to economical saving in cost of feeding in layers chicken, thus may be usefulness for commercial layers chicks production farms.
