Tegegne Journal of Animal and Plant Sciences JAPS 20142014/04/01 24 2 413-417 1018-7081 NA <p>This study was conducted to evaluate effects of non-genetic factors on litter size, age at first parturition (AFP), parturition interval (PI), seasonality of parturition, and pre-weaning mortality rate of sheep and goats flock with 587 kids and 467 lambs owned by 60 households. The litter size, AFP and PI (months) of lambs were 1.52<u>+</u>0.04, 12.43<u>+</u>0.1, 9.19<u>+</u>0.08, respectively, while the corresponding values were 1.47<u>+</u>0.04, 11.95<u>+</u>0.13 and 9.05<u>+</u>0.08 for kids. The average pre-weaning mortality rate was 14.84 and 12.59% for lambs and kids, respectively. Ewes of parity three had (p &lt;0.05) higher litter size than parity one. Does having parity four and five had (p &lt;0.05) higher litter size than parity three while does and ewes having parity three had (p &lt;0.05) higher litter size than parity one. Site and season influenced litter size (p &lt;0.5) and pre-weaning mortality of (p &lt;0.01) lambs and kids. Birth weight (p &lt;0.05) and parity influenced (p &lt;0.01) pre-weaning kid mortality. To exploit reproductive potential of dams and enhance rural income from small ruminants, improved management measures have to be warranted.</p> Litter size, Kids, Lambs, Non-genetic factors,Parturition, Southern Ethiopia Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=2014-JAPS-58
