Abstract
This study was conducted in animal farm of college of Veterinary Medicine, Baghdad University, for 10 weeks (8/3/2010-22/5/2010). The trail was designed to find out the effect of adding two concentrations of Zingiber officinale (2.5 & 5 %) to the concentrate diet (400 gm/ animal/ day) on the number and the activity of the microorganisms and the ecological status of the rumen in Awassi non- pregnant ewes. Nine ewes aged 1.5 years were divided into three equal groups. Group A were given 10 gm, Zingiber officinale animal daily, ie. (2.5 % of diet), while group B were given 20 gm Zingiber officinale animal daily ie. (5% of diet), and the animals in group C was kept as a control group which were given the basal diet without any feed additive. Samples of rumen fluid were collected from all ewes in two periods, the first was after 8 weeks and the second was after 10 weeks from the beginning of the experiment. The results showed significant increase (P<0.05) in the total count of the bacteria of the rumen’s fluid in group A compare with other two groups (B and C), especially during the second period of the experiment. Also similar trend were showed in the protozoa activity, volatile fatty acids, ammonia nitrogen and decrease of the pH of rumen fluid, While there were no significant differences between group B and C during the two periods of the experiment, except that the level of ammonia nitrogen was increased significantly (P<0.05) in group B compare with the control group during the first period (2 hours after feeding).
