Abstract

Feed is the single most important input in increasing chicken and fish culture production and profits. Feeds and feed stuffs are an excellent media for the growth of fungi. Fungi are major spoilage agents of foods and feedstuffs. During manufacturing, feeds can be contaminated with mould spores. The major causing sever feed deterioration (Aspergillus flavus Fungus) was isolated from chicken and fish feed contaminants. So that, the aim of this study was focuses on prevent growth of Aspergillus flavus fungus by using some physical and biological methods. The obtained data presented that, A. flavus was found to reduce significant (P<0.001 and P<0.05) protein and fibers contents and increase fats and moisture percent of contaminated fish feed sample. In in Vivo, data show that, sunlight was found to decrease significant (P<0.001 and P<0.05) the total fungal population (count) of tested chicken and fish feed samples association, as well as increase significantly (P<0.001 and P<0.05) the decreasing percent with increasing the time period to sunlight exposure. In in vitro, data indicated that, data indicated that, propolis extract was found to decrease significant (P<0.001) the linear growth of A. flavus fungus when cultured with 2, 5, 10 and 20% of propolis extract. Increase decreasing percent with increasing the concentration of propolis extract. It was found to effectively suppress mycelial dry weight, significantly (P<0.001) inhibited spore germination (viability) and effectively suppress morphological characteristics causing several changes and damages of mycelia.
