Effect of Different Factors on Mortality Rate of Arsi- Bale Kids in Mid Rift Valley of Ethiopia

摘要

The study was conducted in Anano Shisho and Edogojola of Adami Tulu Jido Kombolcha districtof East shawa zone during May 2009 to June 2010 to determine the effect of different factors on mortality rateof Arsi- Bale goats’ kids. Purposive and simple random sampling was employed as sampling technique toselect two PA and smallholder farmers. The study carried out in this study areas revealed that from a total of536 kids born during May 2009 to June 2010 22.4% (n=120) kids were died. A higher percent 16.4% ( n=88)kids were died in wet season followed by dry 4.5% ( n=24) season of the year. The cause of death for these kidsduring this time is probable due to parasitic diseases, infectious diseases and cold stress of the summerseason of the years. Kids weighing less than 2.9 kg birth weight had mortality rate of 20.7% (n=111) whichdecrease with the increase in kids birth weight. There was a general trend for decreasing in kids’ mortality ratewith increase in parity up to specific parity number. However, the highest kids’ mortality rate was recorded inthe first parity followed by the third parity. Litter size has a significant effect on kids mortality rate (P<0.0001)and female kids were more susceptible to diseases than male kids (67.5 and 32.5%, respectively. Age has asignificant effect on mortality rate Arsi-Bale goat’s kids. Pre- weaning kids mortality rate is higher 34.2% (n=40)than post weaning kid’s mortality rate up to yearling 26.7% ( n=32). In conclusion further detail investigationsof kids’ mortality including every component of reproductive wastage must be done at regional level withrepresenting different agro-ecological zones.
