The aim of this work is to study lamb births and mortalities in Algerian sheep Ouled Djellal breed distributed in different zones of Tébessa region, which is divided according to bioclimatic stage, staff in livestock and area agricultural vocation, into four distinct zones : northern (A, B), middle (C) and southern zone (D).
During two years 2015-2016, birth numbers (BN) and mortality rates (MR) of 355 sheep flocks were recorded using a questionnaire.
Concerning BN the total number was 21244 lambs representing a mean 59±31 per flock.
No significant differences between the birth means of C and D (75 ± 28 vs 83 ± 30) were registered.
Birth mean was significantly higher (P < 0,05) in B (40±17) than A (29 ± 10), when comparison with C and D, the births of A and B were highly significantly (P < 0,001).
According to (BN) the studied region were classified into 3 zone groups : (a) with high lambing rate (C, D); (b) with medium lambing rate (B); (c) with low lambing (A).
In regard to mortality rates, the total rate was 24 ± 6 %.
The (MR) in A (27 ± 5 %) was significantly higher (P<0,05) as compared to other zones (B) 24 ± 4 %, (C) 23 ± 7 % and (D) 22±4%.
However, no significant differences between B, C and D were revealed.
According to the results of (MR) the studied region was classified into two groups : (a) with low MR (C, D), (b) with high MR (A, B).
Our result showed that zones influence the (BN) and (MR) in Tébessa region, and southern zones especially D seems the appropriate to practice breeding of Ouled Djellal breed.
