A total of 444 health piglets were randomly divided into 6 groups, including five medication groups （72 piglets in group A, 74 pig- lets in group B, 72 piglets in group C, 76 piglets in group D, 76 piglets in group E） and one control group （74 piglets）. The piglets in experimental groups were treated drugs once a day for successive 5 days at 30, 60, 90, 120 and 150 of age. The piglets in control group were free of medication. At 70 and 140 days of age, 15 piglets of each group were randomly selected to collect their blood sermn. The Mycoplasma hyopneumoniae （M-Hyo） antibodies in serum were measured by en- zyme-linked immunosorbent assay （ELISA）. During the experiment, the incidence rates of respiratory disease, lung lesion, feed conversion rate, average daily gain （ADG）, and mortality rate of pigs were also observed and recorded. The results showed that the five drugs had significant difference in preventative effects. Group C （Zhiyuanjing group） received the best preventive effect and the highest economic benefits. Compared with control group, the ADG and feed conversion rate in group C were increased by 7.53% and 9.09%, respectively; the incidence rate of respiratory disease was reduced by 13.44% and lung lesion was alleviated by 81.43% ; and the earnings of each pig could rise by 132.70 yuan. The preventative effect and economic benefit of the drugs was sequenced by Chansu Kechuanling and Bingchan Kechuanwang. Wante Feilin and amoxicillin had weaker preventive effects against MPS but greatly influenced growth performance of pigs, so they should be used alternatively with other drugs.展开更多
