Bu çalışma, Akkaraman kuzularının farklı entansif besi sürelerinde ultrasonik ölçümler ile karkas özellikleri arasındaki ilişkileri çok değişkenli bir korelasyonla (kanonik) tahmin etmek amacıyla yapılmıştır. Bu amaçla yaklaşık 2.5 aylık yaşta ortalama 20 kg canlı ağırlıkta 16 adet erkek Akkaraman kuzuları besiye alınmış, 10 günlük alıştırma periyodu ve 70 günlük entansif besi sonunda kesime gönderilmiştir. Hayvanlara besi süresince 150 g kuru yonca otu ve ad-libitum olarak kesif yem verilmiştir. Besi başı, ortası ve sonundaki ultrasonik ölçümler olarak göz kası derinliği, göz kası üstü yağ kalınlığı ile deri kalınlığı bağımsız değişken veri seti olarak alınırken, karkas özellikleri ise bağımlı değişken veri seti olarak alınmıştır. Sonuç olarak Akkaraman kuzularının besi başında kanonik korelasyon katsayıları 0.999, 0.977 ve 0.549 iken; besi ortasında 0.980, 0.931 ve 0.770, besi sonunda ise 0.999, 0.996 ve 0.814 olarak belirlenmiştir. Besi başında ilk kanonik korelasyon katsayıları ve besi sonunda birinci ve ikinci kanonik korelasyon katsayıları istatistik olarak önemli iken (P<0.05), besi ortasındaki kanonik korelasyon katsayıları istatistik olarak önemli olmadıkları saptanmıştır. Sonuç olarak, Akkaraman kuzularının besi süresince alınan ultrasonik ölçümlerinin karkas özelliklerinin tahmininde kullanılabileceği tespit edilmiştir.
This study was done with the aim of predicting the relationship between ultrasonic measurements and carcass characteristics in different entansif nutrition periods with a very varied correlation (canonic). For this purpose, about 2.5 months of age, an average of 20 kg of living weight, 16 male Akkaraman cows were fed, 10 days of exercise period and 70 days of entansif nutrition were sent to the end of the cutting. The animals were given 150 g of dried yellow grass and ad-libitum cutting food during their feeding. As ultrasound measurements in the head, middle and end of the iron, the eye muscle depth, the skin thickness and the eye muscle fat thickness are taken as an independent variable data set, while the cortex characteristics are taken as a dependent variable data set. As a result, the canonic correlation ratings at the food beginning of the Akkaraman cows were 0.999, 0.977 and 0.549; in the food middle 0.980, 0.931 and 0.770, and at the food end 0.999, 0.996 and 0.814. The first canonic correlation ratio at the beginning of the iron and the first and second canonic correlation ratio at the end of the food are statistically important (P<0.05), while the canonic correlation ratio at the middle of the food is not statistically important. As a result, it has been found that the ultrasound measurements taken during the nutrition of the Akkaraman pimples can be used in the prediction of the curcumin properties.
This study was conducted to estimate the relationships between the ultrasonic measurements and carcass characteristics of Akkaraman lambs at different intensive feeding periods with a multivariate correlation (canonical). For this purpose, 16 male Akkaraman lambs with an average of 20 kg live weight at the age of 2.5 months were fed and sent to slaughter after a 10-day training period and 70-day intensive feeding. The lambs were fed with 150 g of dry alfalfa and concentrated feed as ad-libitum during the fattening period. As the ultrasonic measurements were taken at the beginning, middle, and the end of the fattening, eye muscle depth, eye muscle fat thickness, and skin thickness were taken as independent variable data set, while carcass characteristics were taken as dependent variable data set. As a result, the canonical correlation coefficients of Akkaraman lambs were 0.999, 0.977, and 0.549 at the beginning of fattening; 0.980, 0.931, and 0.770 in the middle of the fattening and 0.999, 0.996 and 0.814 at the end of the fattening, respectively. While the first coefficient of canonical correlation at the beginning of the fattening and the first and second coefficient of canonical correlation at the end of the fattening was statistically significant (P<0.05), it was found that the coefficients of canonical correlation in the middle of the fattening were not statistically significant. As a result, it has been determined that the ultrasonic measurements taken during the fattening of Akkaraman lambs can be used to estimate the carcass characteristics.
