Saline pasture improve meat quality in Qinghai Tibetan sheep through changes in the rumen microbiota

Project description:<p>Introduction: This study aimed to investigate the effects of natural forage from different regions (saline-alkali and non-saline-alkali areas) on the rumen microbiota, muscle metabolites, and meat quality of Tibetan sheep. </p><p>Methods: Targeted and non-targeted metabolomics were used to comprehensively analyze both pasture and meat quality, metabolites. Additionally, 16S rDNA sequencing was employed to analyze the rumen microbial community structure of Tibetan sheep.</p><p>Results: The results showed that the natural saline-alkali forage (HG group) had higher protein content, lower fiber content, higher relative feed value, and better quality. Metabolomic analysis revealed significant accumulation of flavonoids and upregulation of amino acid metabolism in the HG group. Additionally, the natural saline-alkali forage significantly increased amino acid deposition in Tibetan sheep muscle, markedly enhanced the redness value (a*), and significantly reduced the yellowness value (b*). Furthermore, the natural saline-alkali forage altered the rumen fermentation patterns in Tibetan sheep, leading to a significant increase in the abundance of F082 and WCHB1-41, while significantly reducing the abundance of Prevotellaceae_UCG-003.

Transcriptome sequencing of sheep hypothalamus tissue reveals the regulatory role of lncRNA in the mechanism of pubertal estrus initiation

Project description:Improving the fertility of sheep is an important goal in sheep breeding as it greatly increases the productivity. Dolang sheep is a typical representative breed of lamb in Xinjiang and is the main local sheep breed and meat source in the region. To explore the genes associated with the initiation of puberty in Dolang sheep, the hypothalamic tissues of Dolang sheep prepubertal, pubertal, and postpubertal periods were collected for RNA-seq analysis on the Illumina platform.

Effects of Magnesium Potassium Sulfate on Tibetan Sheep Quality and Its Volatile and Non-Volatile Metabolic Substancesate the publication title

Project description:<p>Preliminary research conducted by the team has identified that potassium and magnesium may influence the quality of Tibetan lamb meat, although the underlying mechanisms remain unclear. This study aims to examine the impact of dietary supplementation with magnesium potassium sulfate (PMS) on the carcass quality, meat quality, nutritional composition, and flavor metabolites of Tibetan sheep, while also elucidating potential mechanisms through a metabolomics approach. The findings indicate that the inclusion of 0.3% PMS in the diet significantly enhances the carcass quality of Tibetan sheep (P<0.05), evidenced by increases in abdominal wall thickness and backfat thickness by 13.13% and 7.41%, respectively, compared to the control group. Furthermore, the addition of 0.25% PMS significantly elevates pH at 24 hours, a*, and intramuscular fat content, while significantly reducing pH at 45 minutes and b* (P<0.05). Moreover, the supplementation of 0.25% PMS results in significantly higher concentrations of linoleic acid, linolenic acid, EPA, and DHA compared to the control group (P<0.05). The findings regarding volatile compounds demonstrated that the application of PMS facilitated the production of fruity and nutty flavor compounds, including 3-methylpentanoic acid methyl ester and heptanoate methyl ester, while suppressing the accumulation of malodorous substances such as 1-hydrazino-2-propanol. Concurrently, the non-volatile compound analysis revealed that PMS primarily enhances fatty acid biosynthesis by activating the adipocyte cytokine signaling pathway. Additionally, it modulates the sphingolipid signaling pathway to synergistically regulate meat quality, thereby enhancing the flavor profile of Tibetan sheep.</p>

Proteome in Tibetan sheep testes

Project description:We obtained comprehensive protein profiles from testes of Tibetan sheep at three developmental stages (including pre-puberty, post-puberty and adulthood) using data-independent acquisition-based proteomic strategy to quantitatively identify the differentially abundant proteins (DAPs) associated with testicular development and function and to unravel the molecular basis of spermatogenesis in Tibetan sheep.
