“…Consequently, there was a significant correlation between gastrointestinal flora and metabolites of the flora and quality of lamb meat (Du et al, 2022;Ma et al, 2023). Exercise is known to influence a variety of intestinal microbiota in animals (Rebec et al, 2022), and several studies have reported that insufficient animal exercise leads to reduced appetite and weight loss in livestock and poultry, predisposing them to diseases (Jang et al, 2017). The intestinal monolayer epithelium's tolerance to the microbiota is critical, as it provides a physical barrier against intestinal pathogens, while the intestinal crypt is an invagination of intestinal epithelial cells (IECs) (Spence et al, 2011).…”

The transition from grazing to captive rearing resulted in a significant decline in meat quality. To enhance the quality of meat from captive sheep, we examined the impact of exercise on Sunit lambs. The lambs, with similar body weight and aged 3 months underwent a 90-day period of thought-driven exercise. At the end of the exercise period, we collected colonic contents, epithelial tissues, and the longissimus dorsi muscle, and recorded slaughter performance. Exercise was found to have a significant impact on the content of short-chain fatty acids in the colon. Additionally, it generally reduced the mRNA expression of fatty acid absorption transporter genes in the colonic epithelium and lipid metabolism-related genes in the longissimus dorsi muscle. Furthermore, exercise significantly affected the content of fatty acids in the longissimus dorsi muscle of Sunit lambs, and increased its dressing percentage. Exercise influences the composition of fatty acids of the longissimus dorsi muscle and improves dressing percentage by affecting the digestion, absorption, and metabolism of lipids in Sunit lambs. This could be profitable for the livestock industry, and could alter the nutrition and flavor of lamb meat.
