Sultan Qaboos University Journal For Science
A study was carried out to investigate the effects of feeding low quality non-conventional feeds (NCF) containing phenols and condensed tannins on health and performance characteristics in Omani sheep. Twelve Omani sheep were fed one of two base roughages, urea-treated palm frond (UTPF) or Rhodesgrass hay, (RGH) plus a commercial concentrate for 63 days. Haematological, serum biochemical and urine analyses were used to assess sheep health. Serum protein fractions were measured using electrophoresis. Urea-treated palm frond contained higher levels of polyphenols and condensed tannins and fiber than Rhodesgrass hay or concentrate feed. Animals fed UTPF had lower feed intake (P<0.05) and lower body gain (P<0.001) than those fed RGH. Rumen liquor of UTPF-fed animals had higher pH, ammonia-nitrogen and butyric fatty acid but lower acetic fatty acid (P<0.05). Animals fed UTPF had higher neutrophil (P<0.05) but lower lymphocyte (P<0.05) and monocyte (P<0.001) counts by the end of the trial than those fed RGH. There were no effects of diet on serum albumin or globulin fraction levels or albumin:globulin ratio. There were no major effects on urine analysis but there was a trend by control animals to have higher protein and specific gravity than treated ones. This study indicated that feeding low quality non-conventional feeds containing polyphenols or tannins would reduce body gain and may produce some effects on clinical parameters. Although tannins are known to influence protein digestion and absorption in ruminants, it did not significantly affect the serum protein picture in sheep.

The aim of this study is to investigate the role of plasma level parameters during nesting activity and provide data potentially useful to future studies on the dynamics of reproductive and stress hormones in the most endangered sea turtle species in the world. Plasma parameters in the sea turtles, olive ridley (Lipodochelys oliveacea) and hawksbill (Eretmochelys imbricata) from Masirah Island, Oman, were analyzed relative to nesting stress. To date, no study has been conducted on plasma parameter levels in sea turtles during nesting. Field observations were conducted under ideal temperature conditions. At the time of sampling, there was no significant …
Desert Nitrogen Cycles: Fecal Nitrogen From A Population Of The Sahelian Tree Locust In Oman, Michael D. Robinson
Desert Nitrogen Cycles: Fecal Nitrogen From A Population Of The Sahelian Tree Locust In Oman, Michael D. Robinson
Sultan Qaboos University Journal For Science
This research quantifies the amount of nitrogen deposited by the tree locust, Anacridium melanorhodon, during an irregular population outbreak in an Acacia tortilis woodland in Oman. The average standing crop of feces was 65.28g m-2. The mean fecal crude protein and nitrogen were respectively, 20.14 and 3.22 g/100 gash-free dry weight. A hectare of this woodland would contain approximately 1.1 kg of fecal nitrogen beneath the trees. This single contribution by the locusts equals about one-third of the total standing crop of detrital nitrogen under perennial vegetation in a hectare of the Mohave Desert of North America. This, and the …

Plasma composition which includes total protein, cholesterol, lactate, glucose, uric acid, urea, CO2, and electrolytes (Ca++, K+, Na+, Mg++, PO4-3, Cl-), and plasma osmolarity were analyzed in normal adult nesting green turtles Chelonia mydas. Blood samples were collected in June-October at the peak of the nesting season and in November-May during the non-peak period. Plasma electrolytes values, except for PO4-3 and Cl- were significant between the two periods. Values for total proteins and uric acid were significantly different during the two periods but urea values were insignificant. Osmolarity was unchanged during the two periods. During nesting the sea turtles undergo …

Determination Of Sugar And Mineral Contents In Some Omani Fruits, Salma M. Z.Al-Kindy, Abdulrahman O. Abdulnour, Maryam M. Al-Rasbi
Sultan Qaboos University Journal For Science
Omani fruits were analyzed for their reducing sugar, total sugar contents and some minerals. Among the minerals studied were Ca, Mg, Na, K and P. The amounts of total sugar and reducing sugar were within the range of values reported in the literature for the analysis of fruits conducted elsewhere. The amounts of the minerals differ from the reported literature values. This may be attributed to soil composition, climate and type of cultivar.

Ultrastructural Changes In The Epithelium Of The Stomach Of Aphanius Dispar (Cyprinodontidae), Due To Stress From Starvation, Taher A. Ba-Omar, Reginald Victor
Sultan Qaboos University Journal For Science
Ultrastructural changes in the epithelium of the stomach of Aphanius dispar, a cyprinodont fish, due to starvation have been described. The changes in the epithelium after 24, 48, 72, 96, and 120 hours have been discussed. The degeneration of the epithelial cells commenced after 24 hours and steadily progressed till 96 hours at which the maximum change was observed. Changes in response to starvation include the disappearance of lipid droplets, mitochondrial damage, goblet cells degeneration, morphological aberration of the nuclei and overall abnormalities in the structural integrity of the rugae. This study confirms that stress due to starvation causes significant …
