تأثير استخدام معاملات كيميائية مختلفة في القيمة الغذائية و معامل الهضم المختبري لبعض الأعلاف الخشنة الرديئة النوعية

Abstract EN

These experiments were conducted to study the effect of the use of various chemical parameters of some poor quality coarse feed.

The chemical treatments were done for two incubation times, (30 days and 45 day).

The results showed that the chemical treatments were superior at (p < 0.01) with non-treatment in nutritional value and transactions digestion in general, and when a statement of the impact factor of type article forage noted high moral outweight (p< 0.01) for barley straw in the digestion of dry matter coefficient (45.737% ), the coefficient digestion of organic matter (47.490% ), the ration of fibre crude (32.183% ) and demodulator free of nitrogen (55.393% ) on the other feed materials.

When statement of the effect of chemical treatment observed high significant differences (p <0.01) for the treatment of sodium hydroxide in the digestion of dry matter coefficient (44.188% ), the coefficient digest organic matter (50.334% ), the proportion of crude fibre (30.977% ) and demodulator-free nitrogen (57.080) while there was significant deference at for coefficient of urea in crude protein content (11.518% ) and extract ether (2.239% ) as compared with control treatment results.

Which showed the effect of overlap between chemical treatment significant of barley straw in the digestion of dry matter coefficient (52.550% ), coefficient of digestion organic matter (54.040% ), the proportion of crude fiber (30.125% ) and demodulator-free nitrogen (60.989% ) compared to untreated, There was noted superior effect of treatment of wild reeds of urea in protein (15.18% ) and ether extract (3.84% ) compared to other treatment that used in the experiment.
