Success in lamb production depends on their body weight, and
in recent years there had been a growing interest in understanding the impact of
some factors such as parity on sheep productivity. Knowing the factors that affect
the development and growth of lambs can help make changes in breeding plans.
This paper was to detect important factors affecting lamb's birth weight which
usually are not taken to consideration and have substantial part planning
improvement in sheep production. Miss breed sheep were cross or pair with Ile de
France rams three times, with the following characteristics observed; Body weights
of lambs at birth, type of birth, number of lambs born per sheep per parity in the
periods from 2018 to 2020. The result of each lambing per parity of each ewe was
the basis of the study. The ANOVA, general linear model, univariate analysis of
variance, and descriptive statistics derived to assess the following effects: Effect of
parity on lambs’ birth weight; Effect... of parity on birth type, and lambs birth
weight; Interaction effect of different subject effects on birth weight; The
total marginal means of lambing rate per dam in three parities.
The result obtained showed a very significant influence of the indicated factors on
tested traits (P<0.01). Based on the results of our research, we can conclude that
parities have a very significant impact, so they need more attention in the future.
