effect of the feed deprivation periods on total immunuglobolins production and lymphocytes percentage in pullets and cockerels of broiler breeder

ABSTRACT

The aim of the present study was to compare different periods of feed deprivation [day number of starvation in four physical feed restriction programs] on total immunuglobulins and lymphocytes percentage in pullets and cockerels of broiler breeder. A 4X2 factorial experiment based on a completely random design. 160 pullets and 160 cockerels of broiler breeder. Feed intake content weekly was the same for all feed restriction programs and daily feed content according to feed restriction program. During 3 to 20 weeks, chicks were treated with feed restriction programs including daily [without starvation], five days a week, six days a week and skip-a-day. Total immunuglobolins content was determined in the 16
