Using RNA sequencing (RNA-Seq), we analyzed lncRNA expression in the <i>Longissimus thoracis</i> muscle of kids born to goats submitted to two feeding diets: early gestation restriction (50% of maintenance from Day 8–84 of gestation, then 100% until parturition; RM, <i>n</i> = 6) and late gestation restriction (100% from Day 8–84, then 50% until parturition; MR, <i>n</i> = 8). RNA-Seq data underwent quality control, alignment, transcript assembly, and differential expression analysis using Cufflinks and FEELnc pipelines. Three differentially expressed (DE; FDR ≤ 0.05) lncRNAs were identified and classified based on genomic position and predicted regulatory potential. The upregulated <i>lncRNA_10996.1</i> in the RM group was linked to acyl-CoA dehydrogenase family member 10 and GTP-binding nuclear protein Ran-like genes.

In Landes geese aged 180 days (LD180), 624 differentially expressed genes (DEGs) were identified at 5 days post-plucking (481 upregulated and 143 downregulated), whereas 1851 DEGs were identified at 14 days (1350 upregulated and 501 downregulated).

These DEGs were significantly enriched in GO terms, KEGG pathways, and protein–protein interaction networks associated with inflammatory responses (e.g., leukocyte-mediated immunity), and feather regeneration (e.g., epidermis development). Notably, signatures of both innate and adaptive immunity were detected at the early post-plucking stage. Compared with younger geese, the LD180 group showed faster inflammatory resolution than the LD90 group, as demonstrated by a more pronounced decrease in proinflammatory gene expression levels in LD180. Comparative analysis revealed that mechanical damage (such as feather plucking) induces immediate inflammatory and anti-inflammatory responses. In conclusion, the mechanical damage caused by feather plucking triggers a renewed cycle of feather growth, which requires overcoming the harm inflicted by the subsequent inflammatory responses.

Genetic diversity in Belahi cattle has been preserved, likely due to weaker artificial selection and higher historical effective population sizes.
