It is characterized by the formation of granulomas in tissues and organs, more significantly in the lungs, lymph nodes, intestines, liver and kidneys (Shitaye et al. , 2007). Bovine TB is caused by a slowly growing bacillus which is a member of the Mycobacterium tuberculosis complex. Bovine TB is a great threat to both animal and human health in many countries and human tuberculosis of animal origin particularly that caused by Mycobacterium bovis, is becoming increasingly important especially in developing countries (Ameni et al. 2007). Over the years several reports have been made on the prevalence rate of this disease in Nigeria (Babalola and Van veen, 1997; Antia and Alonge ,1981; Nwosu 1987;Cadmus et al. , 2008). Cases of of Bovine Tuberculosis in both herd and Abattoirs have also been reported (Alhajin1976; Cadmus etal. , 1999 and 2003) Abattoir records give an insight into the level of health hazards consumers are exposed to, hence the need to review some of these figures.
Records of animals slaughtered within the state in all government approved slaughter slabs/abattoirs, disease were observed at post mortem examination by Veterinary officers between 2003 to 2010 were used. Postmortem findings were based on characteristic TB lesion on organs as earlier described (Blood and Radostitis,1989; Seifert, 1996; Gracey and Collins, 1992). Data were analyzed to show frequencies of cattle slaughtered and prevalence of the disease.
Result were analysed using Excel 2007 and Epi-info Version Data collected include total number of cattle brought for slaughter which passed through ante and postmortem examination, and the number slaughtered infected with bovine tuberculosis. A total sum of 73,761 cattle were slaughtered throughout the study period (2003-2010) out of which 2,498 (0. 34%) had evidence of TB lesion at postmortem.
The case findings based on the eighteen Local Government Areas of the state is shown in Table 1and 2 respectively and yearly cases and prevalence in table 4. The overall prevalence rate of 3. 4% recorded is higher when compared with 0. 41% recorded for TB in cattle slaughtered at Oko-oba Abattoir, Lagos State
For the past two years, Value Mobile has been working to improve the quality of its phones. Data for 2019 and 2020 follows (in thousands of phones):
Cell phones produced and shipped
Number of defective units shipped
Number of customer complaints
Units reworked before shipping
Manufacturing cycle time (days)
Average customer response time (days)
For each year, 2019 and 2020, calculate the following:
percentage of defective units shipped
customer complaints as a percentage of units shipped
percentage of units reworked during production
manufacturing cycle time as a percentage of total time from order to delivery
Follow the instructions you see on the Data tab of the worksheet (found in Module 5 or by clicking “Next” at the bottom of this page). Show all calculations within the cells of the Excel spreadsheet. This means that you must use formulas and links so that your thought process can be examined. There should be no hard coding of solutions.
