Unsexed day old RIR chicks were uniformly brooded, vaccinated against Gumboro and Newcastle diseases. At the age of 14 days, 10 chicks were assigned to each of the 5 replicates of the 6 dietary groups, fed for 11 weeks and daily group feed intakes were recorded. The control diet (T 1 ) consisted of Maize (34.1%), wheat short+bran (21.0%), limestone (1.20%), salt (0.5%), premix (0.1%), lysine (0.05%), methioinine (0.05%), roasted soybean (27.0%) and noug cake (16.0%); the rest of the diets contained all ingredients in the control plus fishmeal at rates of 3.32% (T 2 ), 6.64% (T 3 ), 9.96% (T 4 ), 13.28% (T 5 ), and 16.6% (T 6 ) of the diet and had 19.76, 18.89, 19.82, 18.44, 18.96 and 19.20% cp, respectively. At the beginning of the feeding trial, 13 chicks representing initial body weight of those in the trial were stunned by dislocation of the neck. At the end, one male and one female chick from each of the 3 replicates of each of the 6 treatment groups were systematically selected, tagged, fasted for 12 hours, weighed, and stunned by dislocation of the neck. All carcasses were kept intact in deep freezer at -20°C and then cut into small pieces in freezing condition, minced and dried in an oven at 65°C for 80 hours, ground, homogenized and chemically analyzed. Chicks fed T 1 had significantly (p 0.001) lowest (68.5g dm, 13.3g cp, 0.54g Ca, 0.35g P and 231kcal me head -1 ) but those on T 6 had the highest daily nutrient intakes (77 g dm, 14.8 g cp, 1.81 g Ca, 0.58 g P and 243 kcal ME head -1 ). T 1 (2.28) of all and T 4 (2.65) among fishmeal groups viz T 2 (3.01), T 3 (2.92), T 5 (2.86) and T 6 (2.85) had the lowest (p -1 d -1 ) than female (2.62 g head -1 d -1 ). Energy retention of T 1 , T 2 , T 3 , T 4 , T 5 , T 6 were 21.6, 28.7, 29.1, 27.0, 25.9 and 28.1 kcal head -1 d -1 , respectively, with significant differences (p 1 and fishmeal groups. Sex had no influence on energy retention. Based on the results of the present study fishmeal can be incorporated up to 16.6% of the diet of rir chicks, however, best results of protein retention was obtained at 3.32%, and of energy retention at 6.64%.","PeriodicalId":245987,"journal":{"name":"Sinet, Ethiopian Journal of Science","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127042426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An experimental plot where neither carbofuran nor plant extracts was applied served as the control treatment. Both carbofuran and plant extracts significantly reduced the soil population of root-knot nematode and galling on the root of pepper, and also improved growth and yield of pepper. Pepper plants treated with carbofuran and 100% concentration of the plant extracts gave the best control of the root-knot nematode.","PeriodicalId":245987,"journal":{"name":"Sinet, Ethiopian Journal of Science","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122464375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 900 m 2 (30 m x 30 m) quadrat was laid following the homogeneity of vegetation in order to collect vegetation data. Investigation of the seedling density and regeneration of target species has been carried out using the same quadrat size. In each of these quadrats, the numbers of all seedlings that are up to the height of 150 cm were recorded. Individuals attaining 150 cm and above in height but less than 10 cm in diameter at breast height (dbh) were considered as sapling and counted. dbh and height of all woody species that are above 150 cm high and more than 10 cm thick were also recorded. Interviews were conducted to collect data on various human pressures exerted on different species. A total of 243 plant species belonging to 85 families were recorded from the Bonga Forest. Of these, 66 families were angiosperms, 2 gymnosperms and 17 monilophytes (ferns). Studies on the structure and regeneration of some woody species indicated that there are species that require urgent conservation measures. Sound management and monitoring, as well as maintenance of biodiversity, cultural and economic values of the forest require conservation activities that promote sustainable uses of the forest and its products.","PeriodicalId":245987,"journal":{"name":"Sinet, Ethiopian Journal of Science","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131679056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

IHAT was set-up in-house and used to test serum samples of cattle against sheep red blood cell (SRBC) coated with crude extracts of C. bovis cyst. Serum samples for screening were collected from Addis Ababa abattoir (n=522), a dairy farm from the suburbs of Addis Ababa (n=101), and a traditional extensive farm (n=109). Postmortem inspection was conducted on a total of 522 animals slaughtered in Addis Ababa Abattoir, out of which 39 (7.5%) were positive for C. bovis.  Thirty-seven of these had viable C. bovis cysts. IHAT titres were determined from serially diluted sera, with a cut-off value set at a titre of 1:64. Cross reaction with other helminths was either absent or very low.  Sensitivity and specificity of the IHAT were 100% and at least 90%, respectively. Based on this test, 149 cattle (28.5%) from the Abattoir, 33 cattle (30.3%) from the extensive farm and 8 cattle (7.9%) from the dairy farm were positive for C. bovis .

In Humera, farmers are largely dependent on this important cash crop for their living. The production rate is, however, lower than the national average. There could be many factors for its reduced productivity, but pests especially sesame seed bug is one of the reasons. In this study, sesame seed weight loss due to sesame seed bug was determined at field and laboratory conditions. At both conditions, there was significant seed weight loss when the packaging materials were unlined jute and unlined polythene bags, although the loss at field conditions was severe. In both setups, there was small seed weight loss when the packaging materials were lined. This could be due to moisture loss from the seeds because the bugs could not penetrate the lined bags. From these, farmers are advised to use lined bags for storage and transport the harvested seeds to their stores as soon as possible.","PeriodicalId":245987,"journal":{"name":"Sinet, Ethiopian Journal of Science","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123921466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
