Effects of Post-Slaughter Carcass Handling on Meat Quality
F. Adzitey§ and N. Huda*
Pakistan Veterinary Journal , 2012,
Abstract: The quality of meat from the processing plant or as found on the market will have an influence on its processing properties and eating qualities. The processing properties and eating qualities will also influence consumers’ acceptability and profits to be realized by producers, processors and retailers. A number of factors including the genetics of the animal, production practices, age of the animal at slaughter and how live animals are handle prior to and during slaughter contribute significantly to meat quality. Apart from these, post-slaughter practices also influence meat quality to an appreciable extent. In recent times, various processing conditions and addition of ingredients/additives have been manipulated to improve upon the quality of processed meat products. This mini-review discusses the effects of post-slaughter practices on meat quality.

Pakistan Journal of Nutrition , 2012,
Abstract: Serunding (shredded meat) is one of the traditional meat based-product popular among Malaysians. Eight commercial serunding prepared using beef, chicken and fish as raw material were collected from markets and analyzed to determine their chemical composition, colour and sensory characteristics. The results showed that moisture, fat and protein contents were within the range of 8.60-13.56, 3.20-31.14 and 19.86-30.15%, respectively. Serunding ayam or shredded chicken was the lightest in colour followed by serunding daging or shredded meat and serunding ikan or shredded fish. Sensory evaluation showed that panelists preferred shredded fish with darker colour. However there was no significant difference between the overall acceptability for shredded meat and chicken.
Effect of whole cotton seed supplementation on the carcass and meat qualities of Djallonke sheep raised on-farm in Ghana
G. A. Teye,,F. Adzitey,,H. K. Dei,A. Kwarteng
Research Opinions in Animal & Veterinary Sciences , 2011,
Abstract: Twenty Djallonke sheep (ten ewes and ten rams) were evaluated for their carcass and meat quality after being fed with whole cotton seed as a supplement over a period of twelve months on-farm. Supplementation with the whole cotton seed had no adverse effect on carcass quality but significantly (P<0.001) improved juiciness. Tenderness, flavour and overall liking were also better in the supplemented group compared to the nonsupplemented group. The results suggest that whole cotton seed could be used as a supplementary feed to improve the productivity and meat quality of small ruminants at a cheaper cost in the study area
Genetic Diversity of Escherichia coli Isolated from Ducks and the Environment Using Enterobacterial Repetitive Intergenic Consensus
Frederick Adzitey
Pakistan Journal of Biological Sciences , 2013,
Abstract: Escherichia coli are mostly free living bacteria that harbour the gastrointestinal tract of poultry. Howbeit, pathogenic Escherichia coli are very important foodborne pathogens that can cause severe complications, illnesses and deaths in humans. The objective of this study was to determine the genetic diversity or relatedness of 62 Escherichia coli strains isolated from ducks and the environment using Enterobacterial Repetitive Intergenic Consensus (ERIC). The analysis of the Escherichia coli strains by ERIC produced DNA bands of different sizes for differentiation purposes and cluster analysis at a coefficient of 0.85 grouped the strains into different clusters and singletons. At this coefficient the Escherichia coli strains were grouped into thirteen clusters and eleven singletons with discriminatory index (D value) of 0.946. The ERIC PCR adapted in this study showed to be a useful genotyping tool for determining the genetic relatedness of the duck Escherichia coli strains. Comparison of the genetic relatedness among foodborne pathogens is important for foodborne diseases outbreak investigations.

Journal of Applied Sciences and Environmental Management , 2010,
Abstract: The microbial quality of 80 meat samples made up of 40 chevon and 40 mutton were collected from the Aboabo, Central-internal, Central-external, and Sakasaka meat shops in Tamale Metropolis and assessed in order to ascertain it safety. Chevon from Aboabo and mutton from the Central market-internal had the highest mean total aerobic bacterial count of 3.9 X 10 6 cfu/cm2 and 3.7 X 106 cfu/cm2 , respectively. The lowest total aerobic count in chevon was found in the Central-internal (6.0 X 105 cfu/cm2) and that of mutton was found in Sakasaka market meat shop (6.0 X 10 5 cfu/cm2). Bacteria isolated from the samples were Escherichia coli, Streptococcus species, Salmonella species , Enterococcus species, and Staphylococcus species, some of which harbor human pathogens of public health concern. The isolation of various bacteria in chevon and mutton sold in the Tamale Metropolis indicates that, lower standard of operating systems in the slaughtering, processing and sale of meats are adhered to. The Government of Ghana, Ministry of Health and Ministry of Food and Agriculture should enforce the laws that prohibit the illegal slaughtering of animals without veterinary inspection, unstandardized methods of handling animals, slaughtering and selling of meats on the open market. @JASEM J.

Abstract: Salmonella species are important foodborne pathogens that can cause illness and death in humans. The objective of this study was to determine the genetic relatedness of 115 Salmonella strains isolated from ducks and their environment using random amplified polymorphic deoxyribonucleic acid (RAPD). The analysis of Salmonella strains by RAPD produced DNA fingerprints of different sizes for differentiation purposes, and cluster analysis at a coefficient of 0.85 grouped the Salmonella strains into various clusters and singletons. S. Typhimurium were grouped into nine clusters and ten singletons, S. Hadar were grouped into seven clusters and nine singletons, S. Enteritidis were grouped into four clusters and five singletons, S. Braenderup were grouped into five clusters and four singletons, S. Albany were grouped into two clusters and seven singletons, and S. Derby were grouped into two clusters and four singletons at a coefficient of 0.85 with discriminatory index (D) ranging from 0.879 to 0.957. With the exception of S. Typhimurium strains which were grouped into three major groups (genotypes) by RAPD analysis, the rest were grouped into two major genotypes. RAPD was a useful genotyping tool for determining the genetic relatedness of the duck Salmonella strains. Comparison of the genetic relatedness among foodborne pathogens and their sources of isolation are important to trace their source and possibly the source of human infection.

Journal of Financial Risk Management (JFRM) , 2018, DOI: 10.4236/jfrm.2018.74020
Abstract: In the repercussions of the latest financial crisis that have occurred on the years 2008-2009, to fortify the stability of the banking systems, policy makers, and the Basel Committee on Banking Supervision—BCBS, together with national regulators have built up a few safety measures, and structures to guarantee that banks establishments keep up adequate capital levels through using risk management tools, in specific the Internal Capital Adequacy Assessment Processes (ICAAP). They all have called for thorough evaluations and assessments for the structure and components of risk management frameworks, tools, and practices whether by banks, regulators, analysts and risk management experts consistently, to ascertain the adequacy of the banking systems, policies, arrangements and techniques for overseeing risks, and guaranteeing the sufficiency of holding appropriate capital levels for confronting normal, as well as adverse and unexpected situations or emergencies. The main objectives of this research study are to shed the light on the ICAAP as one of the main keys of risk management programs, a process by which banks can use to ensure that they operate with an appropriate level of capital, forward looking processes for capital planning covering a broad range of risks across banks, activities beyond simple capital management, and bring together risk and capital management activities in a form that can be used to support business decisions. The research study shall evaluate the significant relationship between the Banking System Stability (dependent variable) and the Internal Capital Adequacy Assessment Process (ICAAP—independent variable) with evidence from the Egyptian Banking Sector.
Creation and Analysis of Earth’s Surface Roughness Maps from Airborne LiDAR Measurements in Downtown Urban Landscape  [PDF]

Journal of Geographic Information System (JGIS) , 2019, DOI: 10.4236/jgis.2019.112015
Abstract: The Earth’s surface roughness constitutes an important parameter in terrain analysis for studying different environmental and engineering problems. Authors gave different definitions and measures for the earth’s surface roughness that usually depend on exploitation of digital elevation data for its reliable determination. This research aimed at exploring the different approaches for defining and extraction of the Earth’s surface roughness from Airborne LiDAR Measurements. It also aimed at evaluating the effects of the window size of the standard deviation filter on the created roughness maps in downtown landscapes using three known approaches namely; standard deviation filtering of the Digital Elevation Model (DEM), standard deviation filtering of the slope gradient model and standard deviation filtering of the profile curvature model. In this context, different roughness maps have been created from Airborne LiDAR measurements of the City of Toronto, Canada using the three filtering approaches with varying window sizes. Visual analysis has shown color tones of small roughness values with smooth textures dominate the roughness maps from small window sizes of the standard deviation filter, however, increasing the window sizes has produced wider variations of the color tones and rougher texture roughness maps. The standard deviations and ranges of the roughness maps from LiDAR DEM have increased due to increasing the filter window size while the skewness and kurtosis have decreased due to increasing the window size, indicating that the roughness maps from larger window sizes are statistically more symmetrical and more consistent. Thus, kurtosis has decreased by 53% and 82% due to increasing the window size to 7 × 7 and 15 × 15 respectively. The standard deviations of the roughness maps from the slope gradient model have increased due to increasing the window size till 15 × 15 while they have decreased with more increases. However, skewness has decreased due to increasing the window size till 15 × 15 and the kurtosis has decreased with higher rate till window size of 11 × 11. In the roughness maps from the profile curvature model, the ranges and skewness have decreased by 93.6% and 82.6% respectively due to increasing the window size to 15 × 15 while, kurtosis has decreased by 58.6%, 76.3% and 93.76% due to increases in the filter window size to 5 × 5, 7 × 7 and 15 × 15 respectively.
