چکیده مقاله:

The objective of this study was to evaluate the morphometric and reproductive traits of indigenous dairy goat types. It was conducted in three districts (Ebnat, Gonji-kolela and Farta) based on the agro-ecological differences, goat population potentials and experience of the farmers using goat milk. Semi-structured questionnaires, field observations, morphological and reproductive trait measurements were used. The results revealed that the average age at sexual maturity of male in Farta district, (Mean±SE) was 7.04 ± 0.41 months. However, age at first service of male goats was longer in Gonji kolela (9.84±0.95) and Ebnat (11.54±1.28) districts. The average body length (BL) for dairy, dual and meat type goats were 59.65 ± 0.58, 54.87 ± 0.69 and 55.52 ± 0.74 cm. The mean rear udder length, udder circumference and teat length were 17.14 ± 0.28, 31.39 ± 0.59 and 3.71 ± 0.07 cm, 14.21 ± 0.48, 26.75 ± 1.01 and 3.41 ± 0.12 cm and 13.44 ± 0.38, 24.67 ± 0.81 and 3.01 ± 0.09 cm, respectively. Whereas, the mean rear udder diameter for dairy, dual and meat types for female goats were 10.04 ± 0.22, 8.66 ± 0.37 and 8.01 ± 0.30 cm, respectively. Dairy type female goats had significantly higher (P
