استخدام فطر Trichoderma harzianum و خميرة Saccharomyces cerevisiae في تخمرات الحالة الصلبة لنخالة الحنطة سابقا حيويا للأداء الانتاجي لدجاج البيض

Abstract EN

This study included prebiotic production from wheat bran fermentation Trichoderma harzianum with Saccharomyces cerevisiae growth in culture medium of, and to know the effect of dietary supplementation this product on productive performance of layer hens.

Used 144 layer hens Lohmann Brown 47 weeks age, were distributed randomly to 12 land pines, each of which was 1.5 x 1.5 m with 12 chickens.

It was divided into four treatments with three replicates.

The treatments were as follows: The first treatment was fed to a standard diet without addition (control), the second, third and fourth treatment fed a standard diet plus prebiotic product of 5, 10, 15 g/ kg, respectively.

The addition of the prebiotic product with layer hen's diets improved production performance through a significant increase in egg weight and egg mass yield and improved feed conversion ratio compared with control treatment.

The improvement of the production performance of chicken eggs experiment was a reflection of the improvement of both intestinal micro flora and the properties of the gut tissue and immune response.AS the number of coliform bacteria decreased significantly, the number of lactic acid bacteria increased significantly, and the number of total bacteria in the intestine did not effect, and the immunity against Newcastle disease increased significantly.

As well as not affected by signs of health, the levels of uric acid and the aminotransferase (AST and ALT) were not affected in the serum of birds fed by adding prebiotic product compared to control birds.

In conclusion, in our study, prebiotic production from wheat bran ferment by fungi T.

harzianum with S.

cerevisiae, its use as promoters for the productive performance of layer hens, add it in diet level of 15 g/ kg.
