 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Study on the Chemical Composition, Intake and Digestibility of Maize Stover, Tef Straw and Haricot Bean Haulms in Adami Tulu District, Ethiopia) ผู้เขียน: Tesfaye Alemu Aredo, N. K.R. Musimba2 สื่อสิ่งพิมพ์:pdf AbstractA study was conducted at two agricultural development sites in Adami Tulu district of Ethiopia to investigate the chemical composition, intake and digestibility of the three major crop residues, namely, maize stover, tef straw and haricot bean haulms produced in the area. Intake and digestibility were determined using nine Borana bulls. Chemical analysis indicated that the by-products have low nitrogen content and are composed of cell wall components with little soluble cell contents. As a result their intake and digestibility were low. Therefore, training of farmers in the application of some crop residue treatment methods and in the use of supplementary feeds is highly recommended. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Production and Utilization of Crop Residues in Three Agro Ecological Zones of Eastern Shoa Zone, Ethiopia) ผู้เขียน:Tesfaye ALEMU,  ดร.พรศรี ชัยรัตนายุทธ์, รองศาสตราจารย์ , ดร.ประวีร์ วิชชุลตา, รองศาสตราจารย์ , ดร.สายัณห์ ทัดศรี, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractTo assess the production and utilization of crop residues in East Shoa Zone of Oromiya Regional State, Ethiopia, 3 Agro Ecological Zones (AEZs), namely, sub-moist (SM2), sub-humid (SH2) and semiarid (SA2) were chosen based on their large area coverage and, a total of 300 households were proportionally selected from these AEZs and interviewed using structured questionnaire. Even if the total annual crop residue produced per household was not statistically different, the contribution of each type of crop residue to the total annual crop residue production per household varied (p<0.05) among the AEZs. With regard to utilization, farmers in all the three AEZs used almost all types of their crop residues primarily for animal feeding. Alternative uses of crop residues were observed to vary more with the type of residue than with the AEZs. It could be concluded that with an annual average production of 0.67 to 1.01 tons per TLU of a household, crop residues contributed to 26 to 40% of the total annual maintenance feed requirement of ruminants. Through the use of improved seeds and other inputs that boosted both grain and residue yields, and by the application of better ways of collection and storage that minimized wastages, farmers could derive more benefits from these valuable feed resources. |
