Abstract
Individual interview, own-flock ranking and group animal ranking experiment were
implemented to define the breeding objective traits for indigenous goats in the study area. Two districts in Arsi Zone, namely, Honkolo Wabe and Lemu Bilbilo were selected
purposively. A pre-tested questionnaire was used for the individual interview with
randomly selected 120 goat producers, 60 from each district. Indices were calculated to
provide the ranking of the purpose of keeping, sources of feed, selection criteria, reasons
for culling and constraints of goat production. In the own-flock ranking experiment 60
households, 30 from each district and 340 goats were used. In the own-flock ranking
experiment, goat owners were asked to choose the first best, second best, third best and
inferior goats. Ten flocks in each district were selected based on the number of goats used
in the own-flock ranking. Top, middle and worst goats were selected from each of the 10
flocks which was allowed collecting 30 breeding females and breeding males were also
ranked. Goats are mainly reared for cash income, milk, meat, manure and saving with the
overall index values of 0.41, 0.15, 0.28, 0.07 and 0.09, respectively. The overall average
(±SE) composition of goat flock structure was 1.79±0.25, 3.90±0.17, 1.29±0.18, 2.18±0.28, 1.63±0.18, 8.39±0.70 and 0.90±0.21 for suckling male kids, suckling female
kids, weaned male kids less than one year, weaned female kids less than one year, matured male greater one year, matured female greater one year and castrated male goat, respectively. Large variation was observed between the first best and the last ranked does
in most of the traits, for example average (±SE) kidding interval 7.55±0.36 and
11.18±0.31 months for the first best and last ranked does, respectively and body weight
36.4±1.4 and 30.3±1.9kg for first best and last ranked does, respectively. From the study, it was concluded that farmers' preference of Arsi-Bale goat keepers through the
individual interview, own-flock ranking and group animal ranking methods were
consistent and comparable in their results. The overall methods indicated that breeding
objective traits identification tools were used to determine breeding objective and to
improve the income of the farmers, improving meat production potential of goats and
market values are important considerations that depend on improving Prolificacy, flock
size and growth rate. From the conclusion, it was recommended that the development of a
selection index for the Arsi-Bale goat breed need to consider the prolificacy, body size
and growth r
