<div>Background: The work was carried out to complementary contribution to the comprehensive study of the recently recognised promising Salem Black goat breed&rsquo;s meat quality raised under intensive and semi intensive systems at different age for both sexes. 
 
Methods: The study was conducted on sixty four, three months old Salem Black goat kids (32 males and 32 females) by allotting randomly as16 kids in each group in a 2 X 2 factorial design. 
 
Result: The pH value for meat was significantly (P&lt;0.05) higher at 9 months male animals. Meat redness (a*) value increased and the lightness (L*) and yellowness (b*) values significantly (P&lt;0.01) decreased with age. The shear force indicates that male had significantly (P&lt;0.01) higher value. Meat at 6 months had significantly (P&lt;0.01) higher sarcomere length. Hydroxyproline content was significantly (P&lt;0.01) higher with lower muscle fibre diameter in intensively reared male kids meat. Acid insoluble ash, ether extract and PUFA contents were significantly (P&lt;0.05) increased with age in meat. Intensively reared animals had significantly (P&lt;0.05) low level of SFA and high level of PUFA, MUFA and PUFA/SFA ratio than semi-intensively reared animals. The intensively reared animal shows better meat quality, more nutritious than semi intensively reared animal meat.&nbsp;</div>

Background: Varietal differences in metabolite composition play a crucial role in determining agronomic traits, nutritional quality and stress resilience in Solanum tuberosum.&nbsp; 
 
Methods: Three potatoes varieties; Longshu 7, Longshu 10 and Longshu 14 were selected and bred by the at the Potato Research Institute of Gansu Academy of Agricultural Sciences between December 2021 to December 2023. Thereafter, comparative metabolomics analysis of three new potato varieties (LS7, LS10 and LS14) was undertaken against the well-established Atlantic cultivar. We employed a bioinformatics-based experimental approach to analyze the metabolomic data obtained from the three new potato varieties (LS7, LS10 and LS14) and the Atlantic cultivar. Metabolite profiling was performed using high-throughput liquid chromatography-mass spectrometry (LC-MS) techniques. Differential metabolite analysis and pathway enrichment analysis were conducted to identify significant metabolic differences and enriched pathways among the varieties.&nbsp; 
 
Result: Results revealed substantial differences in metabolite composition and pathway enrichment between the new potato varieties and the Atlantic cultivar. Metabolites involved in diverse metabolic pathways, including glucoside and hydroxyproline in LS7, kaempferol and ascorbic acid in LS10 and phenyl-butyryl-glutamine and ascorbic acid in LS14, exhibited significant upregulation or downregulation compared to the Atlantic cultivar. Pathway enrichment analysis highlighted the prominence of ABC transporters across all comparisons, suggesting their universal role in mediating cellular processes and stress responses in potato varieties. In conclusion, these findings contribute to our understanding of potato metabolism and pave the way for the development of novel breeding approaches to meet the evolving demands of global agriculture and food security.
