“…With different breeding practices (season and type of control and food system), Ouled Djellal sheep presented different fertility and productivity results, as also observed in the Aragonesa breed in Spain (Abecia et al, 2006), and similar to those obtained for the same breed in the El Tarf region, Algeria (Mebirouk et al, 2019).…”

In this study, a database was created by monitoring 3000 Ouled Djellal ewes, belonging to ten breeding farms and representing two modes of reproduction management. The data collected make it possible to measure the reproductive performance of females and to determine the influence of non-genetic factors on different parameters. The Body Condition Score (BCS) was calculated to compare performance in relation with breeding conditions. The results showed that fertility and prolificacy accounted for 91.1±0.1% and 116.4±0.2% in the reproduction mode respectively based on one lambing/year with exclusive spring control, and of 53.5±0.2% and 101.2±0.1% respectively in the traditional lambing system spread overthe year (with the ram permanently present in the flock) (P<0.05). The BCS varied according to mating season and feeding system. Indeed, as the BCS at mating increased, fertility, prolificacy and productivity improved. Ewes whose BCS at mating was equal to or greater than 3 obtained the best performance, while those with a lower BCS were less fertile, less prolific, and less productive. The average productivity of Ouled Djellal sheep was 107.0±0.1%, and 54.8±0.3%, respectively, in the first and second mode of reproduction management (P<0.05). This study highlights the main sources of variations and their interactions.

Successful sheep farming requires hands-on management and a thorough understanding of the factors that influence it. This necessitates a practical, well-organized approach to ensure the flock's health, productivity, and profitability. Various factors, such as climate, available resources, and management strategies, play a crucial role in determining the success of sheep farming. This study, conducted in the Batna region of Algeria, aimed to assess sheep breeding practices and production performance through a questionnaire distributed to farmers and veterinarians. The study encompassed 14,124 sheep, including 9,435 ewes, from 33 Batna region farms to evaluate production and reproduction performance. The findings revealed that the Ouled Djellal breed is the most prevalent, comprising 61.02% of the sheep population. The results indicated that sheep farming in the region largely relies on traditional extensive grazing systems. It is worth noting that breeding practices have not consistently followed recommended guidelines, as evidenced by a suboptimal sex ratio of 36.28. Additionally, only 21.94% of breeders had employed heat synchronization methods, and artificial insemination was not utilized. The low adoption of artificial insemination is primarily attributed to factors, including a lack of knowledge regarding reproductive management, along with challenges related to illiteracy and limited access to essential resources. The analysis further demonstrated that all categories of sheep were profitable; however, profitability was influenced by factors, such as environmental conditions, feed availability, and the age of the animals. The study underscored significant findings, including the prevalence of the Ouled Djellal breed and the limited use of advanced breeding practices, such as artificial insemination, in the Batna region. The value of the current study lies in its comprehensive examination of traditional sheep farming practices and its recommendations for enhancing productivity. These include improving management practices, increasing access to resources, and promoting genetic improvement by adopting advanced breeding technologies.
