the aim of this study was to evaluate the effect of dietary euphorbia hirta and an acidifier mixture supplementation on gut morphology and some blood parameters of broiler chickens.a total of 240 day old male broiler chicks were randomly assigned to one ofthe four dietary treatment groups including: (1) basal diet (control), (2) basal diet + 7.5 g/kg e. hirta (eh7.5), (3) basal diet + 1.5 g/kg ...

The trial was conducted to evaluate the effect of different levels of dried sweet orange (Citrus sinensis) peel on growth performance in broilers. A total of 400 male broiler chicks (Ross-308) were randomly allocated to treatments varying in supplemental DSOP. The dietary groups consisted of five diets fed for 42 days: control diet without feed additive, diet containing 1.5 % feed additive only...

in this study, the effect of maternal additive genetic and environment on body weight at 6 weeks (bwt6w), breast width (hbrs), carcass weight (carcwt), breast weight (brswt), blood hematocrit value (hem), residual feed intake (rfi), daily feed intake (dfi) and average daily gain (adg) were investigated in a commercial broiler dam line. with and without maternal effects, six different animal mod...
