ABSTRACT: Seven male adult albino mice, each weighing 30-40g and 11months old were used to study the gastric mucosa of the mice. Cell types, their population and percentage densities in the entire gastric mucosa and in each region were determined microscopically. It was observed that mucous producing cells (mucous cells) had the highest population and percentage densities in the gastric mucosa. These were the dominant cell types in both cardiac and pyloric regions of the stomach. In contrast, the body of the stomach is dominated by zymogenic cells. These cells were second in abundance, followed by surface epithelial cells; and parietal cells. Although other cell types were also present in the gastric mucosa but the investigators could not identify them easily. Population and percentage densities of each cell type as calculated by the investigators were as follows: Surface epithelial cells = 99 ± 9.076/200,000cm3 (13%): Mucous cells = 340 ±4/200,000cm3 (45.39%): Parietal cells = 51 ± 42/200,000cm3 (6-8%): Zymogenic cells = 259 ± 17/200,000cm3 (34.60%).

ABSTRACT: This study was carried out to evaluate thequality and Shelf life of three marine fishes (Coral trout, Greasy grouper, and Red mouthed bream) based on total volatile nitrogen test (TVN). The studied fish was collected newly caught from commercial sale point at Khartoum center- Sudan, kept under -4 Co and immediately transferred to laboratory for further analysis. The total volatile basic nitrogen (TVB-N) test was performed to assess the shelf life period and quality status of product at intervals time of 5days extended for 40 days. The results revealed that the total volatile basic nitrogen (TVB-N) ratio in the first two species (coral trout and greasy grouper) reached the recommended limit (30mg/100g) at interval time of 25 days, while the third one (Red mouthed bream) reached the recommended limit in interval time of 20days as the limits of TVN for fishery products in Commission Regulation (EC) NO 2074/2005, which was ranged between 25 to 35 milligrams of nitrogen/ 100grams of fish flesh. It could be concluded that this result can comply with Europe Unite (EU) standard which was widely used in many world countries.
Key words:

Commercial Ostrich Farming in Botswana: A Case Study of Dibete Ostrich Multiplication Unit

Original Research, B37

Moreki J.C., Kebonye N.M., Tiroesele B.
J. Life Sci. Biomed.
, 2(5): 192-195, 2012.

ABSTRACT: Commercial ostrich population in Botswana has declined by about 74.36% from 7800 in 1996 to 2000 currently, indicating that the industry is performing poorly. A study was conducted to ascertain challenges faced by Dibete Ostrich Multiplication Unit (DOMU), a government owned and operated farm. Data were collected through oral interviews of DOMU staff, direct observation and by examining secondary sources of data such as monthly and annual reports from May to July 2011. The challenges faced by DOMU included inter alia high feed costs, poor quality feeds, inadequate extension service, prolonged closure of the ostrich abattoir and high bird mortality. It, however, appears that the prolonged closure of the abattoir is the main contributor to poor performance of the industry. The challenges in this study pointed to the poor performance of DOMU and the ostrich industry in its entirety.
Key words: quality, Shelf life, coral trout, greasy grouper, red mouthed bream, total volatile nitrogen test.

The recorded behavioral activities included: sleeping and rest, movement, clean other, eating, drinking, urination and gonad secretion. It was noticed that the most time consuming activities were sleeping and rest, movement, drinking, and urination. The longest period of the time budget was taken in sleeping and rest (6.7%), (11.15%) respectively in 12hours and 24 hours systems. The shortest fraction of the time budget was spent in gonad secretion maneuvers (0.22%), (0.29%) respectively in the two systems. The main objective of the study was to provide hyena breeders with useful information for better management.

Multiple regression tests have been used in order to test the hypotheses and examine the correlation between the variables. The obtained results indicated a direct correlation between intellectual capital and the efficiency of the capital employed and the firms’ operating profit. Furthermore, according to the results, firms that make more use of intellectual capital have higher net operating profits than firms which use less intellectual capital. The findings of the present research suggest that intellectual capital can be considered as an effective factor in the efficacy of venture units. This finding can come to the attention of the shareholders and managers of these units and encourage them to endeavor, by making managerial modifications, to take the existence of intellectual capitals into consideration and take measures toward using them correctly.

ABSTRACT: Fattening trial of draught oxen was conducted at two rural villages (Robit Bata and Sosetu Yenesa) in Bahir Dar Zuria district to evaluate the contribution of mixture of noug seed cake and wheat bran supplementation compared to farmers feeding practice on body weight changes and economic return. Final body weight and average daily gain (ADG) from 1-45 days were significantly (p< 0.05) higher for the concentrate supplemented oxen. Though body weight gain, ADG from 1-15 days & 1-75 days were higher for the supplemented oxen, the differences were not statistically significant. Economic analysis showed significantly (p< 0.05) higher gross and net return from supplemented oxen than non-supplemented oxen. Therefore, in areas where industrial by-products (noug seed cake and wheat bran) could be purchased in relatively low price, fattening of draught oxen through concentrate supplementation could generate better income from increased body weight and improved body condition of the animals.
