The objective of this study was to evaluate the eating qualities of Arsi, Borana, and Harar Cattle breeds in Ethiopia. A total of 39 bulls with age categories of - 6, and 7 - 9 years were used for the study. The bulls were purchased from mixed crop-livestock systems (Arsi and Harar) and Ranch (Borana) and slaughtered to evaluate the eating quality. WBSF device was used to evaluate instrumental tenderness while sensory panel testing was used to evaluate sensory tenderness, juiciness and flavor. The color of the meat was evaluated using Hunter Lab Mini Scan EZ while water holding capacity was evaluated using filter papers. A complete randomized design was used for the study. Breed significantly affected (P 0.0001) instrumental tenderness with beef from Harar and Boran bulls were very tender (18.55 ± 5.34, 20.34 ± 4.06N, respectively) while beef from Arsi bulls intermediate in tenderness (40.60 ± 0.51N). Beef from all age group of Harar and Boran breeds were

美国环境保护局(EPA)正根据《安全饮用水法规》修订《一级和二级饮用水条例》。一级饮用水标准对每种污染物规定两个数值:一个是只考虑保障健康而制订的不能实施的“推荐最高污染物水平(RMCL)”,另一个是EPA将实施的“最高污染物水平(M... 详细信息

美国环境保护局(EPA)正根据《安全饮用水法规》修订《一级和二级饮用水条例》。一级饮用水标准对每种污染物规定两个数值:一个是只考虑保障健康而制订的不能实施的“推荐最高污染物水平(RMCL)”,另一个是EPA将实施的“最高污染物水平(MCL)”。在考虑可行性、费用以及保障健康的基础上,应使制订的MCL值尽可能接近RMCL值。危险度的考虑,在标准(包含饮用水标准)制订中日益起到作用。之所以采取这种步骤,理由之一是要使各种标准之间愈来愈协调一致。分析一下建议的各种标准,可发现尚未取

目的:检验应用新型连续型对称指数(CSI)检测健康青年女性矢状面下肢关节角度运动对称性的有效性。方法:选取22名健康青年女性随机先后于赤足(BF)或配穿普通运动鞋(NS)状态下以最适步行速度行三维步态测试,用CSI测定两种步行条件下矢状面双下肢髋、膝、踝关节角度及三关节角度的综合对称性情况。结果:22例受试者矢状面下肢关节角度CSI在两种步行条件下均升高,髋、膝关节独立CSI及三关节综合CSI两种状态间差异无显著统计学意义;而踝关节独立CSI(BF:7.6±3.5;NS:9.5±2.8)两种状态间的差异存在显著统计学意义(P=0.013)。结论:健康女性步行时矢状面下肢关节活动存在双侧不对称;CSI指数是步态对称性检测的有效方法。

Open Journal of Animal Sciences 2019年第3期9卷 367-383页

作者： Timketa Dagne Tefera Yesihak Yusuf Mummed Mohammed Yusuf Kurtu Mengistu Urge Letta travis G. O’Quine Jessie L. Vipham Department of Animal Science College of Agriculture Oda Bultum University Chiro Ethiopia School of Animal and Range Sciences College of Agriculture and Environmental Sciences Haramaya University Dire Dawa Ethiopia Department of Animal Sciences and Industry Kansas State University Manhattan USA

The objective of this study was to determine the effect of age and breed of cattle on carcass and meat characteristics in Ethiopia. A total of 39 (Arsi 11, Boran 14 and Harar 14) cattle breeds with age categories of <3, 4 - 6, and 7 - 9 years were used for the study. The bulls were purchased from their respective production system of mixed crop livestock system (Arsi and Harar) and Ranch (Boran). Parameters such as live and carcass weight, meat yield percent, fat characteristics, and primal beef cuts were evaluated. Complete randomized design was used for the study. The live weight of bulls at <3, 4 - 6 and 7 - 9 years ranged 135 - 183, 167 - 181, and 155 - 433 kg, respectively. The carcass weight, dressing percentage, meat yield percent, forequarter, hindquarter, rib eye area, and fat thickness ranged 57 - 209.73 kg, 41.8% - 51.6%, 32% - 58%, 11.7 - 56.42 kg, 14.04 - 45.34 kg, 4.78 - 10.25 square inches and 0.18 - 0.38 inches, respectively. At an early age category (<3 years) meat yield percentage of Arsi, Boran and Harar breeds were 50.86, 30 and 18.72, respectively, and as age category shifted from one age category to the next Harar increased by 13× and Boran by 2.9× and Arsi decreased by -0.93×. The mean rib percentage of Arsi, Boran and Harar were in the range of 7.98 - 9.57, 8.62 - 10.44 and 7.08 - 8.83, respectively. Breed and age of bulls had significantly affected primal meat cuts. Meat yield was predicted from live and hot carcass weight with coefficient determination (R2) of 70.66% and 74.75%, respectively. From the study, it was concluded that age and breeds of cattle had significantly influence on carcass and meat characteristics. Therefore, to determine whether variations were due to genetic or environmental cause’s evaluation of the three breeds under similar feeding condition was recommended.
