title: The Effects ofAgave fourcroydesPowder as a Dietary Supplement on Growth Performance, Gut Morphology, Concentration of IgG, and Hematology Parameters in Broiler Rabbits.
abstract: This study was conducted to determine the effects ofAgave fourcroydespowder as a dietary supplement on the growth performance, gut morphology, serum concentration of IgG, and the hematology parameters of broiler rabbits. A total of 32 rabbits [New Zealand × Californian] were weaned at 35 days. They were randomly selected for two dietary treatments (eight repetitions per treatment), which consisted of a basal diet and a basal diet supplemented with 1.5% dried-stem powder ofA. fourcroydes. On day 60 from the initiation of treatment, gut histomorphology (duodenum and cecum), serum concentration of IgG, and hematology parameters were all measured. The results showed thatA. fourcroydespowder supplementation improved (P< 0.05) the ADFI, ADG, and final BW. Correspondingly, this treatment increased (P< 0.05) the muscle and mucosa thickness and height and width of villi. However, duodenum crypts depth was lower (P< 0.05) when rabbits were fed with this natural product, compared with the basal diet treatment. Results also indicated that theA. fourcroydespowder increased (P< 0.05) the serum concentration of IgG but did not change the hematology parameters. This data indicates thatA. fourcroydespowder, as a supplement, had beneficial effects on increasing the growth performance and serum concentration of IgG, as well as improving the gut morphology without affecting the hematology parameters in broiler rabbits.
