ABSTRACT This study aimed to evaluate the effect of oregano extract added commercial diets on zootechnical performance parameters, carcass yield, immunological conditions, morphometry, and intestinal pH for free-range broiler chickens raised under sanitary challenge conditions. Three hundred chicks strain ‘Heavy red’ were used distributed in a completely randomized experimental design with five...

a total of 240 ross 308 day-old male broiler chicks within a completely randomized design were used in this experiment to evaluate the effects of dietary inclusion of turmeric powder and cinnamon powder on performance and some immune responses of broiler chickens. dietary treatments were as follow: a corn-soybean meal basal diet (control); basal diet + 10 ppm avilamycin; basal diet + 2.5 g/kg t...

Postnuclear supernates from homogenates of essentially pure rabbit heterophil leukocytes were fractionated by means of zonal differential centrifugation through a discontinuous sucrose gradient at various speeds. Three distinct groups of granules were characterized biochemically and morphologically. They were, in order of decreasing sedimentation coefficient: (a) Large, relatively dense granule...
