The Effects of Early Castration on Slaughter and Carcass Characteristics of Norduz Male Kids
(2010) Resul Ciftci, M.; Kor, A.
This study examined the effects of early castration on slaughter and carcass characteristics of Norduz goat male kids. Animal material consisted of 25 male kids divided into two groups-an early castrated group (n = 13) and a control group (n = 12). All animals were weaned at 3 months and then subjected to an 85 days fattening period. Kids were fed with a ration of concentrate (16.6% crude protein and 10.6 MJ kg-1 DM ME) ad libitum +200 g sainfoin per kid twice daily. At the end of the fattening period, eight kids from each group were slaughtered to determine carcass characteristics. Significant differences (p<0.01) were found in the slaughter weights of castrated (24.84±0.465 kg) and intact (30.41±1.061 kg) kids. Cold carcass weights of castrated (9.40±0.230 kg) and intact (11.53±0.544 kg) kids also varied significantly (p<0.05). Muscle, bone, subcutaneous fat and intermuscular fat percentages in the chop region for intact and castrated groups were, respectively, 43.15±0.822 and 41.48±0.579%; 24.60± l .026 and 26.84±0.750%; 7.66±0.711 and 10.21±0.615%; 7.48±0.506 and 7.25±0.693%. It was concluded that early castration had no significant on the carcass characteristics of Norduz male kids. © Medwell Journals, 2010.
Evaluation of Sensory Characteristics of Sheep and Goat Meat by Procrustes Analysis
(Czech Academy Agricultural Sciences, 2012) Keskin, S.; Kor, A.; Karaca, S.
Relationships between sensory variables, species, feeding systems, and panelists were examined by Procrustes Analysis. Six meat groups considering species and feeding type combinations were evaluated by ten panelists for five sensory characteristics (colour, texture, odour, taste, and acceptability). These characteristics were assessed using a nine-point hedonic scale (9 = extremely enjoy, 1 = extremely dislike). Generalized Procrustes Analysis was performed and 61.11% of the total variability was explained by the first two dimensions that correspond to Factor 1 and Factor 2. The first one accounted for 33.99% and the second for 27.12%. Results showed that pasture conditions were reflected in all sensory characteristics of meat of Hair goat as well as Karakas sheep. This study concluded that meat of sheep and goats reared in pasture conditions was more preferable as concerns sensory characteristics than that of fattening animals or those reared in intensive conditions.
Phenotypic Correlations Among Fleece Traits in Norduz and Karakas Sheep
(2011) Kor, A.; Karakus, F.; Tuncer, S.; Yilmaz, A.; Bingol, M.; Cengiz, F.
In this research, it was aimed to determine the phenotypic correlations among some physical traits of Norduz and Karakas sheep. Animal material was consisted from 2-6 years of age of breeding flocks of 50 Norduz and 50 Karakas ewes. Traits measured were greasy fleece weight, fiber diameter, clean fleece percentage, staple length, single fiber actual length, single fiber natural length, breaking strength, elasticity and the number of crimp in 2.54 cm. There was a positive correlation between clean fleece percentage and fiber diameter, it was insignificant for both genotypes. The estimated phenotypic correlations between staple length and greasy fleece weight was 0.403 (p<0.01) and 0.445 (p<0.01) in Norduz and Karakas sheep, respectively. It was understood that traits like fiber diameter, length, fleece weight and the number of crimp should be evaluated together in breeding studies on fleece yield in Norduz and Karakas sheep. © Medwell Journals, 2011.
Quality and Sensory Evaluation for Goat Meat Using Generalized Procrustes Analysis
(2011) Kor, A.; Keskin, S.
The aim of this study was to examine relationships among experts, sex, genotypes and sensory variables by Procrustes analysis. About 10 meat samples involved different genotypes and sex were evaluated by 12 expert assessors for four sensory characteristics (color, texture, taste-odor and acceptability). The attributes were assessed using a nine-point (9: extremely enjoy, 1: extremely dislike) scale. The first two dimension of the analysis accounted for 63.19 and 21.11% of the consensus variance, respectively. As a result of evaluating 12 assessors, it may be concluded that meat of Angora goat has been reflected texture, acceptability and taste-odor of sensory characteristics while that of hair goats has color. © Medwell Journals, 2011.
Slaughter and Carcass Characteristics of Norduz Male Kids Raised in Either Intensive or Pasture Conditions
(2006) Daskiran, I.; Kor, A.; Bingol, M.
The aim of this study was to determine of the slaughter and carcass characteristics of Norduz male kids raised in either intensive or pasture conditions. Hot and chilled carcass dressing percentages in intensive and pasture groups were appeared to be 42.94±0.484% and 41.49±0.503%; 46.26±1.050% and 44.63±1.03%, respectively. In intensive and pasture groups, the omental fat and heart-lungs-liver proportions at slaughter weight of kids were determined as 1.18±0.209%, 0.29±0.065%; 4.75±0.107%, 4.08±0.134%, respectively. The kidney-knob and pelvic fat proportions at left half carcass weight were determined as 2.05±0.196% for kids raised in intensive conditions and 1.06±0.182% for kids raised in pasture conditions. In the rack joints, the lean portions of the intensive group and pasture group kids were 46.42±0.892% 50.50±1.990%, respectively. Total fat portions which contain subcutaneous fat and intermuscular fat were determined as 10.05±1.020% in intensive group and 4.16±0.477% in pasture group. In this study, it was concluded that; pasture group kids had similar slaughter and carcass characteristic values as intensively raised ones due to the special environmental condition and rich flora of the mentioned Norduz region of Van province. © Asian Network for Scientific Information, 2006.
