Abstract

This project has been conducted in New Zealand in 1999, as a requirement for feed production companies to control salmonella in feed by Ministry of Agriculture and Fisheries (MAF). Feed is the most important factor in poultry production enterprises because of its impact on cost and health. It takes the feed about two minutes to reach the 80 ºC. The feed could be recycled if didn’t reach the 82-83 ºC planned. Steam temperature was stable and around 130 ºC. This temperature could be optimized to reduce energy cost without affecting the pelleting process through tracing the feed in temperature (ingredients) one can say, that some of the steam is entering to the feed-in tube and raising the feed-in temperature to 46-50 ºC. The regular incoming feed temperature was between 20-25 ºC. The die temperature was 92 ºC, and cooler temperature for the feed out was 20 ºC

Abstract

The results of detecting fungi associated with nineteen poultry feed samples from different locations in Baghdad governorate revealed that the feed samples varied in type of isolating fungi, the percentage of occurrence, the frequency of isolation and total fungal load. The genus Aspergillus recorded the highest percentage of occurrence (100%) in samples B11, B13 and B17. Sample B19 recorded the highest total fungal load (1910 x 106 cfu) while sample B12 recorded the lowest total fungal load (0.04 x 106 cfu). The results of toxigenic activity showed that only 7 isolates among 19 isolates had toxigenic activity, and isolate B6 was the highest aflatoxin B1 production in comparison with other isolates.

أظهرت نتائج التحري عن الفطريات المرافقة لتسعة عشر عينة من أعلاف الدواجن المجموعة من مناطق مختلفة في محافظة بغداد تباين العينات من حيث أنواع الفطريات المعزولة وتكرار وجودها في العينات المدروسة والحمل الفطري الكلي للعينات. سجل الجنس Aspergillus أعلى نسبة مئوية للوجود وصلت 100% في العينات B11 ،B13 وB17 هذا من ناحية ومن ناحية اخرى سجلت العينة B19 أعلى قيمة للحمل الفطري الكلي التي بلغت (1910 ×106 cfu) في حين سجلت العينة B12 أقل حمل فطري والذي بلغ (0.04×106 cfu). أظهرت النتائج قابلية 7 عزلات من بين 17 عزلة على انتاج الافلاتوكسين B1 في حين كانت العزلة B6 أكثرها قدرة على انتاج هذا النوع من السم.
