Fungal And Trichothecenes (Tct) Contamination Of Poultry Feed From Duhok Province, Kurdistan Of Iraq, L. F. Hussei A. A. M. Saadullah

Al-Qadisiyah Journal of Pure Science

Fungi are capable of reducing the nutritional value of food for human and animals and producing many mycotoxins. Mycotoxins-contaminated animal feed has adverse effects on productivity and animal health. As well, mycotoxins may be carried over into meat and eggs when poultry are fed with contaminated feed. Data on the occurrence of T-2 and HT-2 toxins in poultry feed from Kurdistan region of Iraq are very limited. T-2 toxin is the most toxic type A trichothecene mycotoxin. It is the secondary metabolite of the Fusarium fungi, and is common in grains and animal feed. Toxic effects have been shown both …

Al-Qadisiyah Journal of Pure Science

In this paper, the continuous Boubaker scaling functions were constructed with the presentation on the interval [0,1], which obtained depending on Boubaker polynomials. In this current study the Boubaker scaling polynomial has been applied for solving the nth order integro–differential equations (IDE’s). The collocation method with the aid of Boubaker scaling functions together were utilized to transform the higher order integro–differential equations into a problem of linear system algebraic equations. Some numerical examples were added to show the simplicity and accuracy of the proposed technique. The results have been compared with the exact solution using Matlab and illustrated by graphs.
