In response to climate change, the use of digital livestock systems and probiotic mixtures as technological strategies to improve animal health and production is driving new innovations in the farm animal industry. However, there is little information available regarding the effects of digital livestock systems and probiotic mixtures (consisting of , and ) on the growth performance of the growth-finishing swine. Thus, the objective of this study was to investigate the effects of digital livestock systems and probiotic mixtures on the immune function, cecal bacteria, short-chain fatty acids, nutrient digestibility, and growth performance of growth-finishing swine. A total of 64 crossbred male swine (Duroc × Landrace × Yorkshire, average body weight: 60.17 ± 1.25 kg) were randomly assigned to four treatment groups: CON (control group with a conventional livestock system without a probiotic mixture), CON0.4 (a conventional livestock system with a 0.4% probiotic mixture), DLSC (a digital livestock system without a probiotic mixture), and DLS0.4 (a digital livestock system with a 0.4% probiotic mixture). The swine were reared under standard environmental conditions until their average body weight reached 110 kg. The results indicated that the growth performance of the swine improved with an increase in nutrient digestibility and immune function modulation of blood immune markers in the group with a digital livestock system compared to the CON group, although the growth performance of the swine was similar between the DLSC and CON0.4 groups. Moreover, the application of the digital livestock system and the probiotic mixture maintained higher levels of Lactobacillus and balanced short-chain fatty acid profiles compared to the CON group. These results suggest that a digital livestock system and a probiotic mixture can improve the growth performance of swine by enhancing their nutrient digestibility, improving their immune function, and maintaining balanced cecal bacteria and short-chain fatty acids. Therefore, this study provides insights into the application of digital livestock systems and probiotic mixtures as a climate change response strategy to improve swine production.
为应对气候变化，使用数字畜牧系统和益生菌混合物作为改善动物健康和生产的技术策略，正在推动家畜养殖业的新创新。然而，关于数字畜牧系统和益生菌混合物（由 、 和 组成）对生长育肥猪生长性能的影响，目前可用信息很少。因此，本研究的目的是调查数字畜牧系统和益生菌混合物对生长育肥猪免疫功能、盲肠细菌、短链脂肪酸、养分消化率和生长性能的影响。总共64头杂交公猪（杜洛克×长白×约克夏，平均体重：60.17±1.25千克）被随机分配到四个处理组：CON（传统畜牧系统对照组，不使用益生菌混合物）、CON0.4（使用0.4%益生菌混合物的传统畜牧系统）、DLSC（无益生菌混合物的数字畜牧系统）和DLS0.4（使用0.4%益生菌混合物的数字畜牧系统）。猪在标准环境条件下饲养，直到其平均体重达到110千克。结果表明，与CON组相比，数字畜牧系统组猪的生长性能随着养分消化率的提高和血液免疫标志物免疫功能的调节而改善，尽管DLSC组和CON0.4组猪的生长性能相似。此外，与CON组相比，数字畜牧系统和益生菌混合物的应用使乳酸杆菌水平更高，短链脂肪酸谱更平衡。这些结果表明，数字畜牧系统和益生菌混合物可以通过提高猪的养分消化率、改善其免疫功能以及维持盲肠细菌和短链脂肪酸的平衡来提高猪只的生长性能。因此，本研究为数字畜牧系统和益生菌混合物作为应对气候变化以提高生猪产量的策略的应用提供了见解。
