تقييم إحلال نسب مختلفة من فضلات فروج اللحم المربى في الأقفاص و الحاوي على يرقات الذباب المنزلي في عليقة فروج البط المحلي : بعض الصفات الفسلجية و قياسيات القناة الهضمية

Abstract EN

Experiment was carried at the water fowl farm , College of Agriculture , University of Basrah during the period from 27/12/2010 to 21/2/2011.

The aim was to determine evaluation of replacing four levels of dried broiler manure with the larvae of flies (Musca domestic) in some physiological characteristics and some measurements of the small intestine in local ducks.

At two week of age a total of 48 male and 36 female duckling were randomly treated to four groups in three replicated, with four male and three female duckling .

Chicks fed during the incubation period in a free commercial diet containing 22% crude protein and 2900 Kcal/Kg metabolic energy.

At fourteen days of age, chicks fed four experimental diets , the first diets was control ( basal diets) and replacing dried broiler manure containing housefly larvae instead of basal diet in the level of 7.5 , 15 , 22.5 % in treatment T2 , T3 and T 4 respectively.

The results showed Significant decreased (P<0.05) in cholesterol plasma levels compared with control treatment, while there were no significant differences observed in plasma glucose, total protein, albumin, globulin and uric acid among different treatment.

Also , there was no significant difference in weight and relative weight of duodenum and jejunum among the treatments.

A significant increase (P< 0∙05) recorded in size and percent of size of duodenum and jejunum among in replacing treatment as compared with control.

In ileum size and relative sizes there was significantly highest (P<0.05) in T3 and T4 in chicks received dried broiler manure with the larvae of flies than T1 and T2 .

A significantly improvement (P<0.05) in intestine length and size in replacing treatment than control.

The speed of the passage of food in small intestine did not show any significant 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) in apparent digestibility in T4 compared to the rest treatments .

On other hands first treatment achieved highest protein digestibility, either in protein efficiency ratio T2 and T3 was the best among others in this trails.
