Efficiency of the oestrus synchronization with hand mating and artificial insemination on the reproductive performances of Woyto-Guji Goat under community-based breeding program

Abstract

The present study was designed to describe the efficiency of oestrus synchronization on Woyto-Guji goats under  community-based breeding program in Konso zone. Single and double injections of PGF2α followed by AI and single  injection followed by buck mating were the protocols applied. Percent responded, inseminated, conceived, delivered,  aborted, time of insemination, gestation length and litter size were data collected for the experiment. A total of 177 does  were used for oestrus synchronization by using PGF2α hormone. Overall, the findings revealed that about 88.14%  of the does expressed oestrus within 57.48±2.64 hours after hormone administration. The overall percent inseminated,  conceived, delivered and aborted and gestation length (day) were 91.67, 93.71, 72.03, 2.82%, and 152.48±2.34,  respectively. The overall percent of kid sex born was about 51% female and 49% male, and litter size was about 58%  single and 42% twin. The response rate was significantly affected by age (P<0.05). Percent inseminated, conceived, kid  delivered and time of insemination were significantly affected by protocol, parity and age (P<0.05). Buck mating on  hormone treated does was relatively easily applicable for increased conception rate under the community level.
