Carcase weight and Dressing Percentage are increased using Australian Sheep Breeding Values for increased weight and muscling and reduced fat depth
Meat science, 2014Co-Authors: G E Gardner, A Williams, A J Ball, R H Jacob, G. Refshauge, J. E. Hocking Edwards, Ralph Behrendt, D W PethickAbstract:Abstract Pre-slaughter live weight, Dressing Percentage, and hot standard carcase weight (HCWT) from the 2007, 2008, 2009 and 2010 birth-years of the Information Nucleus Flock Lambs (n = 7325) were analysed using linear mixed effects models. Increasing the sire breeding value for post-weaning weight (PWWT), and c-site eye muscle depth (PEMD), and reducing the sire breeding value for fat depth (PFAT) all had positive impacts on HCWT. The magnitude of the PWWT effect was greater in pure bred Merinos compared to Maternal and Terminal sired progeny. The improved HCWT resulting from increased PEMD was entirely due to its impact on improving Dressing Percentage, given that it had no impact on pre-slaughter live weight. There were marked differences between sire types and dam breeds, with pure-bred Merinos having lower pre-slaughter weight, reduced Dressing Percentage, and lower HCWT than progeny from Terminal and Maternal sired lambs or progeny from Maternal (1st cross) dams.

selection for eye muscle depth breeding value increases Dressing Percentage in lambs
Gardner G.E. ORCID: 0000-0001-7499-9986 Williams A. Ball A.J. Jacob R.H. and Pethick D.W. ORCID: 0000-0002-3255-7677 (2013) Selection for eye muscle d, 2013Co-Authors: G E Gardner, A Williams, A J Ball, R H Jacob, D W PethickAbstract:Pre-slaughter live weight taken directly off pasture and hot standard carcase weight data was collected from 7,849 lambs produced at 8 sites across Australia over a 4 year period (2007-2010) as part of the Sheep Cooperative Research Centre’s information nucleus flock experiment. These lambs were the progeny of 363 Terminal, Maternal, and Merino sires divergent for post-weaning eye muscle depth breeding values (PEMD). Dressing Percentage was calculated by dividing hot standard carcase weight by pre-slaughter weight expressed as a Percentage, and all three of these terms were analysed using a linear mixed effects models. The base model included fixed effects for site, year of birth, kill group, sex, birth-rear type, sire type and dam breed, with sire and darn identification included as random terms. Sire post-weaning fat depth, weight, and PEMD breeding values were included as covariates. The PEMD breeding value was found to have no effect on pre-slaughter weight, however it did increase (P<0.01) hot standard carcase weight by 1 kg across the 7 unit PEMD range. This increase was attributable to the impact of sire PEMD on Dressing Percentage which increased (P<0.01) by 1.7 Dressing Percentage units across the PEMD range. This represents a clear production advantage for producers using high PEMD sires, the progeny of which will have a similar live weight to low PEMD sires, but will deliver heavier carcase weights on the basis of their improved Dressing Percentage. Although live growth rate does not appear to be impacted, the implications for feed efficiency due to reduced fat deposition are currently being explored.

Biotechnology in Animal Husbandry, 2007Co-Authors: D Ostojicandric, Vladan Bogdanovic, S Aleksic, M M Petrovic, B Miscevic, V Pantelic, S JosipovicAbstract:Differences in Dressing Percentage and content of different tissues in carcasses of Domestic Spotted breed and crosses F1 generation with Charolais and Limousine breed were investigated. Total of 30 carcass sides were dissected, 10 in each genetic group. Genotype exhibited very significant effect (p<0,01) on Dressing Percentage and content of tissues, except for connective tissue. The highest Dressing Percentage was determined in crosses with Charolais (59,92%) followed by crosses with Limousine (59,85%), with statistically significant difference (p<0,01) to Dressing Percentage established for heads of domestic Simmental breed (55,71%). Crosses with Charolais and Limousine realized considerably higher content of muscle tissue (81,5% and 80,7%) compared to heads of domestic Simmental breed (77,86%). Content of bone tissue of 16,45% in carcasses of domestic Simmental breed was considerably higher (p<0,01) compared to both groups of crosses, whereas the content of fat and connective tissue was considerably higher (p<0,05) only in relation to crosses with Limousine.

Dressing Percentage of meat from crosses of Pirot pramenka and merino landshaf breed as indicator of meat production
Biotehnologija u stocarstvu, 2004Co-Authors: M. Zujovic, S Josipovic, Milos Lukic, P Zorica Tomic, Zlatica Pavlovski, Ivan Pavlović, S. IvanovicAbstract:Investigations were performed on lambs raised in cooperative farms and farm of ZZ STOCAR in Dimitrovgrad, immediately after the pasture fattening on Stara Planina Mountain in duration of 150 days. By random selection, 30 lambs of each sex were selected from male and female herds consisting of 300 and 200 lambs, respectively, in the second week of October, and were used for investigation of the Dressing Percentage. Fattening period lasted 240 days. The loss of live weight in transport to slaughterhouse was 8.24% in case of male lambs, and 8.33% in case of female lambs. Average body mass of male lambs was 32.07kg, and female lambs 27.70kg. Dressing Percentage of carcasses from male lambs was 48.18, and of females 48.15%. With high quality nutrition the mass of carcasses and Dressing Percentage in improved Pirot Pramenka breed are noticeable increased. Dressing Percentage of meat from lambs of improved Pirot Pramenka breed fattened on pasture can considerably be increased in relation to previous results obtained from non-fattened lambs. This fact indicates that the fattening is the best way to provide higher quantities of meat also of improved quality from lambs of Domestic Pramenka breed. It should also be pointed out that Dressing Percentage determined for lambs of improved Pirot Pramenka breed doesn't fully satisfy standards, however, the improvement can be achieved by modernization of the fattening technology and improved conditions of nutrition and care. This type of fattening complies with the standards of EU as ecologically produced food, that is meat.

investigation of factors affecting the results regarding the Dressing Percentage value of male young cattle of domestic simmental breed and crossbreds of domestic simmental and limousine breed
Biotechnology in Animal Husbandry, 2002Co-Authors: S Aleksic, B Miscevic, S Josipovic, M M Petrovic, Z Pavlovski, Dusica TomasevicAbstract:Carcass Dressing Percentage (Dressing Percentage of two carcass sides) or slaughter Dressing Percentage is proportional share of carcass, that is carcass sides, in relation to mass prior to slaughtering. Beef carcass consists of two carcass sides, regardless of the sex, on which, after bleeding, skin, head, lower leg parts (in carpal and tarsal joints), internal organs of the pectoral, abdominal and pelvic cavities, sexual organs, kidney and pelvic fat, diaphragm, tail and spinal cord were separated. In order to investigate factors significant for results related to slaughter Dressing Percentage, experiment with two trial groups of approximately same mass prior to slaughtering was carried out. First trial group consisted of young cattle of Domestic Simmental breed (DS, n=7) average mass of 592,7 kg, and the second group consisted of crossbreds of Domestic Simmental breed and Limousine (DSL, n-7) average mass of 589,9 kg. Mass of warm carcass sides with and without kidney fat, mass of internal organs (kidneys, liver, lungs, heart and spleen), mass of head, tongue, tail, skin and muscle cuts from diaphragm were measured. Based on obtained results it was established that male young cattle - crossbreds of Domestic Simmental breed and Limousine breed achieved better Dressing Percentage by 4,55% compared to young cattle of Domestic Simmental breed. In case of young cattle of Domestic Simmental breed, proportional share of skin mass was higher by 1,6% compared to crossbreds. Also mass of muscle cuts obtained from diaphragm was higher by 0,09% in case of Domestic Simmental cattle. For remaining investigated anatomical parts no significant differences were determined. Total mass of internal organs of young cattle of Domestic Simmental breed was higher by 0,36% compared to internal organs of crossbreds of Domestic Simmental and Limousine breed. The mass of spleen of young Domestic Simmental cattle was by 0,23% higher in relation to crossbred cattle.

Estimation of Dressing Percentage and carcass traits on slaughter weight in Sudanese zebu cattle
International Journal of Bioassays, 2015Co-Authors: M Lado Milton, Salah Khatir Jubarah, Erneo B. OchiAbstract:This Study was conducted at the Hilat Kuku Research Centre to determine the effect of slaughter weight on the slaughter traits and the whole sale cuts. A total of thirty-three bulls of the Western Sudan Baggara breeds were used. They were allocated purposively into three groups based on slaughter weights. Carcasses were measured and the slaughter traits determined statistically using ANOVA and Duncan Multiple Range Test. The results indicated that the external offal and viscera weights increased with an increase of slaughter weight. The Dressing Percentage on slaughter and empty body weight basis showed no significant difference (P> 0.05) due to differences in slaughter weight. Shrinkage Percentage declined from 3.0 to 1.9 as slaughter weight increases. Carcass length and chest width and leg circumference increased insignificantly with the increase of slaughter weight. While shin length and abdominal depth increased significantly (p

While shin length and abdominal depth increased significantly (p<0.05) with an increase of the slaughter weight. Whole sale cuts Percentage increased with an increase of slaughter weight. Some of the cuts decreased with an increase of slaughter weight. Most of the slaughter traits are influenced by slaughter weight. Hence, the thin flank could be utilized to predict the carcass weight. Further comparative study is needed with the South Sudanese Nilotic zebu bulls.

Carcase weight and Dressing Percentage are increased using Australian Sheep Breeding Values for increased weight and muscling and reduced fat depth
Meat science, 2014Co-Authors: G E Gardner, A Williams, A J Ball, R H Jacob, G. Refshauge, J. E. Hocking Edwards, Ralph Behrendt, D W PethickAbstract:Abstract Pre-slaughter live weight, Dressing Percentage, and hot standard carcase weight (HCWT) from the 2007, 2008, 2009 and 2010 birth-years of the Information Nucleus Flock Lambs (n = 7325) were analysed using linear mixed effects models. Increasing the sire breeding value for post-weaning weight (PWWT), and c-site eye muscle depth (PEMD), and reducing the sire breeding value for fat depth (PFAT) all had positive impacts on HCWT. The magnitude of the PWWT effect was greater in pure bred Merinos compared to Maternal and Terminal sired progeny. The improved HCWT resulting from increased PEMD was entirely due to its impact on improving Dressing Percentage, given that it had no impact on pre-slaughter live weight. There were marked differences between sire types and dam breeds, with pure-bred Merinos having lower pre-slaughter weight, reduced Dressing Percentage, and lower HCWT than progeny from Terminal and Maternal sired lambs or progeny from Maternal (1st cross) dams.

selection for eye muscle depth breeding value increases Dressing Percentage in lambs
Gardner G.E. ORCID: 0000-0001-7499-9986 Williams A. Ball A.J. Jacob R.H. and Pethick D.W. ORCID: 0000-0002-3255-7677 (2013) Selection for eye muscle d, 2013Co-Authors: G E Gardner, A Williams, A J Ball, R H Jacob, D W PethickAbstract:Pre-slaughter live weight taken directly off pasture and hot standard carcase weight data was collected from 7,849 lambs produced at 8 sites across Australia over a 4 year period (2007-2010) as part of the Sheep Cooperative Research Centre’s information nucleus flock experiment. These lambs were the progeny of 363 Terminal, Maternal, and Merino sires divergent for post-weaning eye muscle depth breeding values (PEMD). Dressing Percentage was calculated by dividing hot standard carcase weight by pre-slaughter weight expressed as a Percentage, and all three of these terms were analysed using a linear mixed effects models. The base model included fixed effects for site, year of birth, kill group, sex, birth-rear type, sire type and dam breed, with sire and darn identification included as random terms. Sire post-weaning fat depth, weight, and PEMD breeding values were included as covariates. The PEMD breeding value was found to have no effect on pre-slaughter weight, however it did increase (P<0.01) hot standard carcase weight by 1 kg across the 7 unit PEMD range. This increase was attributable to the impact of sire PEMD on Dressing Percentage which increased (P<0.01) by 1.7 Dressing Percentage units across the PEMD range. This represents a clear production advantage for producers using high PEMD sires, the progeny of which will have a similar live weight to low PEMD sires, but will deliver heavier carcase weights on the basis of their improved Dressing Percentage. Although live growth rate does not appear to be impacted, the implications for feed efficiency due to reduced fat deposition are currently being explored.

Carcass weight, meat yield and meat cuts from Arado, Boran, Barka, Raya cattle breeds in Ethiopia
Journal of Agricultural Science, 2019Co-Authors: Y. Y. Mummed, E.c. WebbAbstract:This study was conducted with the objective to evaluate carcass weight, meat yield and primal meat cuts of beef from Arado, Boran, Barka, Raya and nondescript cattle breeds slaughtered at export abattoirs in Ethiopia. Data was collected from Abergelle and Melgawendo export abattoirs in 2011. The result of the study revealed that the average live weight, warm carcass weight, cold carcass weight and warm Dressing Percentage of cattle slaughtered at the abattoirs studied were 241.41±0.37 kg, 106.93±0.21 kg, 101.19±0.18 kg and 44.21±0.05%, respectively. Live weight, carcass weight and Dressing Percentage were differ (P < 0.001) between abattoirs, seasons and breeds of cattle slaughtered. Average meat yield and yield Percentage of cattle slaughtered at Abergelle abattoir was 61.56±0.94 kg and 67.81±0.33%, respectively. Meat yield and weight of primal meat cuts were different (P < 0.001) between breeds of cattle. Yield Percentage was significantly (p < 0.05) different between seasons. Retailed meat yield was significantly predicted (R2 = 88.1%) from slaughter weights, Topside (R2 = 77.86), Silverside (75.64), Knuckle (R2 = 70.13), Striploin (R2 = 70.73), Tenderloin (R2 = 61.33), Shank (R2 = 64.55) and Rumpcap (R2 = 64.48). From the study it was concluded that Boran cattle was better in Dressing Percentage compared to most cattle breeds in Africa while the Dressing Percentage and meat yield of Arado, Barka and Raya breeds were less than the percent and yield reported for other zebu cattle in Africa. A strategy should be devised to improve the carcass weight, Dressing Percentage and retail able meat yield from local cattle in Ethiopia.
