LncRNAs are regarded as regulators in various animal reproductive physiological processes. However, the regulation of lncRNAs in the reproductive organ development of Hu sheep with different prolificacy remains unknown. Herein, numerous tissue-unique and -common differentially expressed lncRNAs (DELs) and differentially expressed genes (DEGs), and fecundity-unique DELs and DEGs were identified among different comparison groups at horizontal and vertical levels. Moreover, the tissue-unique and -common, and fecundity-unique female reproduction-associated DEGs and DELs were screened, and the interaction networks were constructed. Furthermore, MSTRG.43442.1 was mainly present in the cytoplasm of tested cells. The key genes ADAMTS1 and DCN were mainly localized in the granulosa cells, pituitary cells and/or endometrial epithelial cells of ovary, pituitary and/or uterus. Overall, this study identified large numbers of unique and common DELs and DEGs in the female reproductive organs of Hu sheep with different prolificacy and provided new insights into understanding the regulation of Hu sheep fecundity.

Tong sheep, known for their superior meat quality and disease resilience, face breeding challenges due to low prolificacy, unlike Hu sheep, which exhibit higher fertility and growth rates. This study identified over 700,000 genetic variants between these breeds through pooled whole-genome sequencing. Functional analysis reveals key differences in pathways related to fat metabolism, insulin signaling, and cell cycle regulation.

Article Synopsis
  • * A study using genotypes from 81 flocks found that nearly all genetic variation (99.9%) comes from a single ancestral population, suggesting a current population size of around 150, but the breed should actually target a reference population of 15,000 for better genomic prediction accuracy.
  • * The average inbreeding level was about 16.6%, with specific genomic regions linked to production traits showing high levels of shared genetic material; addressing these could help improve selection outcomes,

Article Synopsis
  • - The study analyzed 837 ewes from specific Iranian sheep breeds and one Greek breed to explore genetic factors related to prolificacy using OvineSNP50K arrays.
  • - Researchers applied statistical analyses to identify 19 genomic regions across various chromosomes that are under selection for prolificacy traits.
  • - Bioinformatic analysis indicated these regions contain candidate genes tied to prolificacy, milk yield, and body weight, suggesting opportunities for future research on genetic links to sheep prolificacy traits.

This study aimed to estimate genetic parameters, including heritability and repeatability, for milk yield and prolificacy in sheep. It included 3682 records from 1837 ewes across various breeds: Awassi, Assaf, and Awassi x Assaf crosses, two Awassi lines: Improved Awassi, AFEC Awassi. The study measured total milk yield (TMY), yield up to 120 days (TMY120), and yield up to 150 days (TMY150), alongside reproductive traits: litter size (LS), number of lambs born alive (NLBA), and lambing interval (LI).

Growth and reproductive performance traits are important economic indicators for analyzing the overall performance of breeding systems. This study aims to evaluate the comparative performance of two Algerian sheep (Rumbi and Hamra) in terms of growth and reproductive performance, and the effect of factors such as breed, season of birth, mode of birth and age of the mother on this performance in a semi-intensive breeding system. The reproductive performance of 577 Rumbi ewes and 1328 Hamra ewes bred at the Tiaret and Saïda experimental stations respectively, was analyzed using performance monitoring data.
