Abstract
In this study, live weights after shearing, mohair weight and some mohair characteristics of Angora goats were obtained. Data were collected from Angora goat flock reared at Lalahan Livestock Research Institute. The research was conducted between 2001 and 2004 years. The effects of year and animal age on those of traits were estimated. Least squares means of 1, 2, 3, 4, 5, 6+ ages groups for body weights after shearing were 22.57±0.431, 31.90±0.478, 38.28±0.508, 40.62±0.524, 44.50±0.539, 46.12±0.577 kg, for mohair weight were 1704±86.8, 2434±61.8, 2873±63.8, 3013±68.9, 3216±80.3, 2974±89.1 g respectively (P<0.05). Least squares means for fibre diameter, length, resistance, elasticity were also estimated and results of same ages groups were 30.06±0.645, 33.48±0.436, 36.35±0.478, 35.47±0.536, 35.60±0.646, 36.86±0.671 µm for fibre diameter; 6.06±0.178, 6.23±0.126, 6.19±0.141, 6.27±0.154, 6.43±0.180, 6.70±0.196 cm for fibre length; 8.69±0.230, 9.46±0.232, 10.22±0.262, 11.21±0.268, 10.70±0.281, 10.66±0.303 g for fibre resistance; 36.30±0.642, 37.51±0.648, 40.31±0.730, 39.41±0.747, 41.45±0.780, 38.52±0.844% for elasticity respectively. The effect of age on body weight after shearing, mohair weight, fibre diameter, resistance, elasticity was statistically significant (P<0.001), but not significant on fibre length (P>0.05)
Özet
Bu çalışmada, Lalahan Hayvancılık Merkez Araştırma Enstitüsü’nde yetiştirilen Ankara keçisi sürüsünün 2001-2004 yılları arasındaki kayıtları kullanılarak; kırkım sonu canlı ağırlığı, tiftik verimi ve bazı tiftik özellikleri incelenmiştir. Üzerinde durulan özelliklere yıl ve yaşın etkisi En Küçük Kareler Yöntemi ile tahmin edilmiştir. Sürüde 1, 2, 3, 4, 5, 6+ yaş gruplarına ait en küçük kareler ortalamaları, kırkım sonu canlı ağırlığı için sırasıyla 22.57±0.431, 31.90±0.478, 38.28±0.508, 40.62±0.524, 44.50±0.539, 46.12±0.577 kg; tiftik ağırlığı için 1704±86.8, 2434±61.8, 2873±63.8, 3013±68.9, 3216±80.3, 2974±89.1 g olarak tespit edilmiştir. En küçük kareler ortalamaları, yaş sırasına göre elyaf çapı için 30.06±0.645, 33.48±0.436, 36.35±0.478, 35.47±0.536, 35.60±0.646, 36.86±0.671 µm; lüle uzunluğu için 6.06±0.178, 6.23±0.126, 6.19±0.141, 6.27±0.154, 6.43±0.180, 6.70±0.196 cm; mukavemet için 8.69±0.230, 9.46±0.232, 10.22±0.262, 11.21±0.268, 10.70±0.281, 10.66±0.303 g; elastikiyet için ise % 36.30±0.642, 37.51±0.648, 40.31±0.730, 39.41±0.747, 41.45±0.780, 38.52±0.844 olarak belirlenmiştir. Yaşın kırkım sonu canlı ağırlığı, elyaf çapı, mukavemet ve elastikiyet üzerine etkisi önemli (P0.05).
