This study aimed to determine how the route of antimicrobial administration affected the growth performance of weaned piglets. Additionally, we aimed to investigate potential differences between antimicrobial resistance developed by antimicrobials administered orally through drinking water, and those administered through feed, in weaned piglets. The research was undertaken on a farm housing 500 sows and involved 150 weaned piglets at 21 days of age. These piglets were evenly distributed into three groups of equal size: water, feed, and control. Antimicrobials were administered through drinking water and feed in the water and feed groups, respectively, while the control group received no antimicrobial treatment. The observation of piglets continued until they reached 70 days of age. The feed conversion ratio in the water group (1.7 ± 0.78) was significantly higher than in the control (2.4 ± 1.77) and feed (2.7 ± 1.68) groups. Additionally, the route of administration did not affect antimicrobial resistance rates. Based on these results, it can be inferred that administering antimicrobials through drinking water is advantageous for pig farming.
本研究旨在确定抗菌药物的给药途径如何影响断奶仔猪的生长性能。此外，我们旨在调查断奶仔猪通过饮水口服给药与通过饲料给药所产生的抗菌药物耐药性之间的潜在差异。该研究在一个饲养500头母猪的农场进行，涉及150头21日龄的断奶仔猪。这些仔猪被均匀地分为三组，每组大小相等：饮水组、饲料组和对照组。抗菌药物分别通过饮水和饲料给予饮水组和饲料组的仔猪，而对照组不接受抗菌药物治疗。对仔猪的观察持续到它们达到70日龄。饮水组的饲料转化率（1.7±0.78）显著高于对照组（2.4±1.77）和饲料组（2.7±1.68）。此外，给药途径不影响抗菌药物耐药率。基于这些结果，可以推断通过饮水给予抗菌药物对养猪业有利。
