Evaluation of replacing various levels of dried broiler manure reared in cages containing house fly larvae in diet of local ducks 2- some physiological characters and gut measurements

Abstract

Experiment was carried at the water fowl farm , College of Agriculture , University of Basrahduring the period from 27/12/2010 to 21/2/2011. The aim was to determine evaluation of replacing fourlevels of dried broiler manure with the larvae of flies (Musca domestic) in some physiological characteristicsand some measurements of the small intestine in local ducks. At two week of age a total of 48 male and 36female duckling were randomly treated to four groups in three replicated, with four male and three femaleduckling . Chicks fed during the incubation period in a free commercial diet containing 22% crude proteinand 2900 Kcal/Kg metabolic energy. At fourteen days of age, chicks fed four experimental diets , the firstdiets was control ( basal diets) and replacing dried broiler manure containing housefly larvae instead of basaldiet in the level of 7.5 , 15 , 22.5 % in treatment T2 , T3 and T 4 respectively. The results showed Significantdecreased (P<0.05) in cholesterol plasma levels compared with control treatment, while there were nosignificant differences observed in plasma glucose, total protein, albumin, globulin and uric acid amongdifferent treatment. Also , there was no significant difference in weight and relative weight of duodenum andjejunum among the treatments. A significant increase (P< 0∙05) recorded in size and percent of size ofduodenum and jejunum among in replacing treatment as compared with control. In ileum size and relativesizes there was significantly highest (P<0.05) in T3 and T4 in chicks received dried broiler manure with thelarvae of flies than T1 and T2 . A significantly improvement (P<0.05) in intestine length and size inreplacing treatment than control. The speed of the passage of food in small intestine did not show anysignificant differences between the treatment. While the percentage of passage speed of food decrease(P<0.05) for the replacing treatment as compared to control. There was significant decline (P< 0∙05) inapparent digestibility in T4 compared to the rest treatments . On other hands first treatment achieved highestprotein digestibility, either in protein efficiency ratio T2 and T3 was the best among others in this trails
