Performance and ileal characteristics of finishing Broilers fed diets supplemented with prebiotics (Mannose and Lactose)
Journal of Animal Science and Veterinary Medicine
An experiment was conducted to evaluate the effect of prebiotics supplemented diets on performance characteristics and gut morphology of broiler chickens. The study involved 320 day-old Anak broiler chicks, used to assess the utilization of prebiotics [Mannose oligosaccharides (MOS) and Lactose oligosaccharides (LOS)] by broiler chicks. The chicks were alloted to eight treatment groups of 40 birds each and four replicates of 10 birds each in a 2 x 4 factorial arrangement. The additives (MOS and
... additives (MOS and LOS) were added to the diets at four levels (0, 250, 500 and 750 ppm) per additive. The birds were fed for 56 days, after which data on feed intake, body weight gain, feed conversion ratio and ileal morphology were collected. The data was subjected to analysis of variance and significant means were separated using Duncan's Multiple Range Test. Results showed that final weight values significantly (p<0.05) ranged from 1276.67 to 1503.38 g. The ileum morphology of the finishers broilers showed that villi height, lamina propria depth, basal width and apical width were significantly (p<0.05) influenced by prebiotic sources and levels. The villi height of 2250.00 µm was highest at 500 ppm MOS level of inclusion, while the least value of 538.30µm was obtained in birds fed 0ppm Lactose inclusion. It was therefore, concluded that, prebiotic MOS at 500ppm could be used in feed to obtain the better weight gain and FCR, with normal gut morphology of broiler chickens.
