Two hundred Cobb-500 one-day-old broilers used were randomly grouped into two treatments of five replicates and 20 birds per replicate in a deep litter system. The birds in the first group were fed with 2mm and 4mm die size pelletized feed at the starter and finisher phase respectively while commercial mash feed grade was applied at the starter and finisher phase for birds in the second group. The experiment lasted 7 weeks. On the last week of the experiment, 4 birds per replicate were separated into the metabolic compartment for the ilea digestibility trial and they were offered feed treated with chromic oxide at 200mg/kg diet for five days. On the 6th day, the birds were slaughtered and the ilea contents of the gut were collected for the proximate, energy, and chromic oxide content determination. Performance traits and morphometric measurement of the internal organs and intestinal components of the birds were taken with cut samples preserved in 10% formalin solution for histological assessment. The result showed a significant difference (p<0.05) in the performance parameters measured with the birds-fed pellet having higher feed intake, body weight gained, and better feed conversion ratio. There was no significant difference (p>0.05) in the length of the duodenum, jejunum, and ileum, including organ weights (heart and liver) between the two treatments while the gizzard weight was higher (P<0.05) in birds fed mash feed form. Ilea nutrient digestibility for ether extract was higher (p<0.05) in birds on pellet. It was deduced from the results that although mash feed form improved gizzard development, better feed conversion was observed in birds fed pellet feed form with significant positive influence on the gut morphometric and ilea nutrient digestibility.","PeriodicalId":325280,"journal":{"name":"ARC Journal of Animal and Veterinary Sciences","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121478895","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}

They multiply in blood stream, lymphatic vessels and tissue, including cardiac muscle and the central nervous system [1]. Trypanosomosis is transmitted by tsetse flies (Glossina species) and believed to be the most important infectious disease holding back development of livestock production in Africa [2]. Trypanosomosis is one of the major constraints on animal production in areas of Africa which have the greatest potential for significant increases in domestic livestock productivity [3]. Tsetse flies occur over some 10 million square kilometer of Africa [4] affecting a total of 38 countries. Currently, about 37% of the 147 million cattle in countries affected by tsetse are exposed to the disease. Africa produces 70 times less animal protein per unit area than Europe [5]. The disease in Africa costs livestock producers and consumers an estimated US$1340 million each year [6]. In Ethiopia above 14 million heads of cattle are exposed to the risk of trypanosomosis, 20,000 heads of which die every year. Annual estimated losses for Ethiopia as a result of trypanosomosis is roughly US$200 million, in terms of mortality and morbidity losses in livestock (excluding utilization of fertile land for crop and livestock production) and the costs included in controlling the disease. In the years 1978-1982 a total of 9,675,575 doses of trypanocidal drugs were purchased with 17,920,780.70 birr [7].","PeriodicalId":325280,"journal":{"name":"ARC Journal of Animal and Veterinary Sciences","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121189087","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}
