Bu araştırma, enstitü ve yetiştirici elinde gen kaynağı olarak korunan Ankara keçilerinde 2011-2015 yılları arasında yürütülmüştür. Enstitü ve yetiştirici elinde (Ayaş ve Beypazarı) korunan Ankara keçilerinde doğum oranı sırasıyla % 92.8, 88.8 ve 82.5, bir doğumdaki oğlak sayısı 1.15, 1.15 ve 1.07, oğlaklarda 90. gün yaşama gücü % 92.4, 88.6 ve 82.7, 180. gün yaşama gücü % 87.8, 85.0 ve 79.5, doğum, 90. ve 180. gün canlı ağırlıkları 2.64±0.02, 2.40±0.01 ve 2.18±0.02 kg, 13.72±0.22, 12.80±0.10 ve 12.01±0.19 kg, 20.23±0.30, 19.20±0.13 ve 17.92±0.26 kg, keçilerde kırkım sonu canlı ağırlık 33.95±0.22, 32.46±0.11 ve 29.38±0.12 kg, tiftik verimi 2.26±0.03, 2.18±0.02 ve 1.81±0.01 kg tespit edilmiştir. Enstitü sürüsünde elyaf çapı 37.15±0.21 µm olup yaş ve yılın etkisi önemli (p bir değişiklik göstermediği görülmüştür.

Investigation of Various Production Traits of Angora Goat Herds Kept as Gene Source Both Ex Situ and In Situ Conditions

This study was carried out to investigate the various production traits of Angora goat herds kept as a gene source both ex situ and in situ in vivo conditions between 2011-2015 years. For this purpose, three herds, one of them from Lalahan Livestock Research Institute (Ex situ conserved) and two of them from private breeders in Ayas and Beypazarı districts in Ankara (In situ conserved) were included in the study. So, the herds were named as Institute, Ayas and Beypazarı. The least squares means of Institute, Ayas and Beypazarı herds were 92.8, 88.8 and 82.5% for birth rate; 1.15, 1.15 and 1.07 for litter size; 92.4; 88.6; 82.7% at 90th days survival rate of kids; 87.8, 85.0 and 79.5% at 180th days survival rate of kids; 2.64±0.02, 2.40±0.01 and 2.18±0.02 kg at birth, 13.72±0.22, 12.80±0.10 and 12.01±0.19 kg at 90th days and 20.23±0.30, 19.20±0.13 and 17.92±0.26 kg at 180th days for kids weights; 33.95±0.22, 32.46±0.11 and 29.38±0.12 kg for goat live weights after shearing; 2.26±0.03, 2.18±0.02 and 1.81±0.01 kg for mohair yield, respectively. The effect of age and year on fiber diameter (37.15±0.21 µm) in Institute herd were significant (p<0.001). Lactation milk yield and lactation duration in Ayas herd were determined as 85.21±3.57 kg and 175.13±3.18 days while udder width, udder depth and udder circumference were obtained as 11.72±0.22, 13.63±0.23 and 39.75±0.60 cm, respectively.As a result, fertility and survival rate traits Angora goats kept as gene resource were satisfactory level at Institute herd. Ayaş herd was partly similar, but Beypazarı herd was lower, compared with Institute herd in terms of production traits. It was also observed that no significant changes in body measurements over many years in Angora goats
