Three trails were carried out at Salah-aldin governorate – Baiji which started at 23rd of October to the 10th of December of 2001. First trail aimed to study the effect of using industrial water, which is a waste water from northern company for fertilizer production substituted for normal water as a broilers drinking water. Second trail aimed to study the effect of using 5 or 10% of canola seed meal irrigated with industrial water or normal water. Third trail aimed to study the effect of adding 5% of canola seed oil irrigated with industrial or normal water compared with diet added 5% of sunflower oil on some microbial groups of marketed broiler intestine content included total bacterial count (TBC), coliform count (CC), fungi count (FC) and lactobacilli count (LC). The data obtained revealed the following results:
First trail: using industrial water from northern company for fertilizer in Baiji as a broiler drinking water substituted for normal water significantly (P<0.05) increased TBC and LC to 11.64 and 3.84 log No. / gm of broiler intestine content drank 100% industrial water respectively and decreased CC to 6.11 log No. / gm of broiler intestine content. No significant differences in FC were noticed , which ranged from 8.21 to 8.32 log No. / gm of broiler intestine content.
Second trail: results of using 5 or 10% of canola seed meal irrigated with industrial water and the same percentages from this meal irrigated with normal water compared with diet added 5% of soybean meal indicated no significant differences in the TBC, CC, FC and LC.
Third trail: no significant differences were appeared in the counts of the studied microbial groups due to canola seed oil from plants irrigated with industrial water compared with normal water. When as the differences between 5% sunflower oil added and 5% of canola seed oil increased TBC and LC and decreased CC and FC. Thus using industrial water from northern company for fertilizer production in Baiji as a drinking water substitute for normal water have positive effects to promote Lactobacilli and normal flora of broiler intestine content at marketed age.
