Propolis has been considered a good candidate for health amelioration and disease prevention over a long period of time. Effect of feed supplementation with Chinese ether extract propolis was evaluated for the antibacterial action on (Ross 308) broiler chicks and their litter over 35 days. The addition of different levels of propolis (100, 250 and 750 mg/kg diet) on total aerobic and coliform bacteria as well as Lactobacillus spp. and bifidobacteria were determined. Supplementation of propolis significantly increased (p0.05) the desired stimulating effect of Lactobacillus spp. and Bifidobacteria in fecal samples of all treatment groups compared to control group. However, propolis did not have an impact to reduce the total aerobic and coliform bacteria compared to control group in both fecal and litter samples. In conclusion, Chinese propolis improved the beneficial normal gut microflora and had a limited effect on the total aerobic and coliform bacteria in broiler chicks and litter quality

The present work studied the prenatal development of the rabbit gallbladder. It was carried on 14 embryos. The collected material which covered most of the prenatal developmental stages ranged from 10 to 30 days. The gall bladder was observed for the first time as a solid mass at 13 embryo. In the advancing ages, the gall bladder was elongated pear-shaped consisting of neck, body and fundus and lied in a fossa on the visceral surface of the right lobe. Excavation of the gallbladder began at 14 day embryo from the neck towards the fundus, in the form of small vacuoles. Complete excavation was observed at 24 day embryo. At this time, the structure of the wall was well established consisting of tunica mucosa, tunica muscularis and tunica serosa or adventitia.
