Aim: The aim of this study was to determine body measurements, testicular characteristics and udder traits in Turkish Hair goat reared under the extensive conditions.

Materials and Methods: The data were collected from 17 different flocks. 17 body measurements, 11 udder and 6 testis traits were recorded from 675 females and 63 bucks.

Results: Live weight, withers height, chest girth, rump height, body length were detected as 51.2 kg, 74.8 cm, 86.8 cm, 75.8 cm and 80.6 cm, respectively in female Hair goats. Same measurements were determined to be 82.8 kg, 86.6 cm, 100.7 cm, 86.0 cm and 93.7 cm for males. Udder length, udder width, udder girth, udder depth, teat length, teat width and teat angle were detected as 7.5 cm, 10.1 cm, 36.1 cm, 18 cm, 5.8 cm, 2.6 cm and 49.3 grade, respectively. Scrotal circumference and scrotum length were determined as 29.9 cm and 20.5 cm respectively. The effects of area, flock and age were significant for all body measurements and udder traits (except sternum height and udder placement shape) for females (P<0.01-0.001). The highest phenotypic correlation was detected as 0.82 (female) and 0.87 (male) between live weight and chest girth (P<0.05).

Conclusions: Morphological characteristics and the relative production traits of these were investigated in a very large population of traditional reared mature Hair goats.
