Fifteen local isolates of Pseudomonas were obtained from several sources such as soil, water and some high-fat foods (Meat, olives, coconuts, etc.). The ability of isolates to produce lipase was measured by the size of clear zone on Tween 20 solid medium and by measuring the enzymatic activity and specific activity. Isolate M3 (as named in this study) was found to be the most efficient for the production of the lipase with enzymatic activity reached 56.6 U/ml and specific activity of 305.94 U/mg. This isolate was identified through genetic analysis of the 16S rRNA gene. and it was shown that the isolate M3 belongs to Pseudomonas aeruginosa with 99% similarity.&n

 Seventeen local isolates of Bacillus were isolated from soil to produce extracellular xylanase under submerged fermentation process by using xylan as carbon sole source. All isolates were subjected  to quantitative scanning to select the most efficient one. The highest activity of xylanase (2680u/ml) was obtained from isolate Bacillus sp RS1. The isolate identified by 16SrRNA gene sequence of Bacillus subtilis  ( accuracy of 99%)which was matched with sequence of Bacillus subtilis VBN25 that recorded in Genebank under the Accession Number of

This study was conducted to investigate the effects of birth number, pregnancy stage (pre- and post-pregnancy), and their interaction on selected blood parameters in local Awassi ewes under grazing conditions. The experiment involved 33 local Awassi ewes, divided equally into three groups: the first group consisted of ewe lambs, the second group included ewes with one previous birth, and the third group comprised ewes with multiple births (2–3). Birth number showed no significant effect on any of the blood parameters. However, mean corpuscular hemoglobin concentration (MCHC), hemoglobin (Hb), and packed cell volume (PCV) were significantly higher at mid-pregnancy (12th week) compared with the 4th and 20th weeks of pregnancy.
