Öğe DETECTING THE RELATIONSHIP OF CALIFORNIA MASTITIS TEST (CMT) WITH ELECTRICAL CONDUCTIVITY, COMPOSITION AND QUALITY OF THE MILK IN HOLSTEIN-FRIESIAN AND BROWN SWISS CATTLE BREEDS USING CART ANALYSIS(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2018) Aytekin, Ibrahim; Eyduran, Ecevit; Keskin, IsmailThe aim of this study was to describe the relationship between mastitis and electrical conductivity, milk composition, milk quality in dairy cattle. California mastitis test (CMT) was used to make a diagnosis of mastitis in the cows, and considered as a binary response variable i.e. healthy and unhealthy. Conductivity, color measurement (L* and a*), milk fat, calving month and freezing point were considered as independent variables in the model. All the animals were classified with overall accuracy of 89.6 (%) or the error of 10.4 (%) in diagnosis of mastitis by using Classification and Regression Tree (CART) data mining algorithm. CART algorithm correctly classified unhealthy cows with an accuracy of 77.2%. The algorithm correctly classified healthy cows with a marvelous accuracy of 95.7% and a marvelous area value under ROC curve of 0.924, P=0.000). It was concluded that some measurements i.e. CMT, electrical conductivity, milk color values, milk composition and quality may be used to accurately detect mastitis together with the help of the CART algorithm.Öğe Fattening performance and carcass characteristics of Akkaraman lambs in different housing systems(AGRICULTURAL RESEARCH COMMUNICATION CENTRE, 2015) Karabacak, Ali; Aytekin, Ibrahim; Boztepe, SaimThis study was carried out to determine the fattening performance, body measurements, and slaughter and carcass characteristics of Akkaraman lambs fattened under indoor and outdoor housing systems. Fourteen Akkaraman lambs were used for the current study Lambs were less than 3 months of age having about 20 kg live weight, and fed concentrated feed ad libitum together with 150 g of dehydrated alfalfa per day for 8 weeks. The daily live weight gain of Akkaraman sheep in the indoor housing system was 313 g while this value was 277 g a day in the outdoor housing system (P<0.05). Also, the average total feed intakes (kg) and the feed conversion ratios of Akkaraman lambs in indoor and outdoor shelters were found to be 148.81 kg and 146.95 kg, and 4.10 and 4.49 (P>0.05), respectively. The differences between the housing systems in terms of total chest depth increase, chest depth and total body length increase were statistically significant (P<0.05). Moreover, the differences in dressing percentage (P<0.01), heart+lungs+liver weight (P<0.05), fore-ribs weight and proportion (P<0.05) from slaughter and carcass characteristics were statistically significant Also, the pH, hardness and color values as L*, a*, b*, H* and C* at 24 h after slaughter were determined.Öğe Fattening performance and carcass traits of Anatolian Merino lambs in indoor and outdoor sheepfolds(AGRICULTURAL RESEARCH COMMUNICATION CENTRE, 2015) Karabacak, Ali; Aytekin, Ibrahim; Boztepe, SaimThe objective of this study was to determine the fattening performance and carcass traits of Anatolian Merino lambs under different housing systems. Average daily live weight gains (DLW Gain, g), total feed intakes (Total FI, kg) for each stall and the feed conversion ratios (FCR) of Anatolian Merino lambs in indoor and outdoor sheepfolds were found to be 262 and 270 g, 125.2 and 128.8 kg, 4.63 and 4.76 (P>0.05), respectively. The differences between the groups in warm carcass weight (33.07 and 34.90 kg, respectively), cold carcass weight (15.65 and 17.65 kg, respectively), leg weight (2.64 and 2.98 kg, respectively) (P<0.05), dressing percentage (47.32 and 49.61 %, respectively) and M. Longissimus dorsi area (12.79 and 16.45 cm, respectively) were significant (P<0.01). Also, the pH (P<0.05), hardness (P<0.05) and the colour values (P>0.05) of the eye muscle area and subcutaneous fat were also determined.Öğe Fatty Acid Composition and Conjugated Linoleic Acid Content in Different Carcass parts of Daglic Lambs(HINDAWI PUBLISHING CORPORATION, 2014) Karabacak, Ali; Aytekin, Ibrahim; Boztepe, SaimThis study was conducted to compare fatty acid composition and content of conjugated linoleic acid (CLA) in different regions of sheep carcasses. Lambs of the Daglic, breed were used for this purpose. Subsequent to a 68-day period of intensive fattening, fatty acids were examined in samples taken from the legs, shoulders, breasts, and ribs of lamb carcasses. According to the analysis, in leg, shoulder, breast, and rib, respectively, total saturated fatty acids (SFA) were found to be 40.38, 42.69, 42.56, and 40.27%, unsaturated fatty acids (MUFA) were found to be 40.38, 44.17, 46.17, and 49.50%, polyunsaturated fatty acids (PUFA) were found to be 4.79, 4.29, 3.80, and 3.72%, and CLAs were found to be 1.49, 1.69, 1.53, and 1.59%.Öğe FATTY ACID COMPOSITION AND CONJUGATED LINOLEIC ACID CONTENT IN DIFFERENT CARCASS PARTS OF MALYA LAMBS IN INTENSIVE FATTENING(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2018) Aytekin, Ibrahim; Karabacak, AliThis study was conducted to determine the fatty acid composition in different carcass regions such as in the leg, shoulder, rib and breast regions of Malya lambs. Total saturated fatty acids (SFA), unsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), trans fatty acids (TFA) and conjugated linoleic acid (CLA) values were found as 43.48, 40.90, 5.08, 9.10 and 1.44 in leg region, respectively. These values were found to be 42.99, 42.76, 4.93, 7.97 and 1.35 in shoulder, 41.63, 45.44, 4.51, 7.09 and 1.33 in rib, and also 39.55, 50.18, 3.30, 5.83 and 1.14 in breast regions, respectively. When the results are examined, the region where the SFA and TFA values are lowest and the MUFA value is highest is the breast region. The region with the highest is the breast region. The region with the highest values of PUFA, TFA and CLA is the leg region.
