Effect of the butyric acid producing strain Clostridium butyricum MIYAIRI588 on broiler and piglet zootechnical performance and prevention of necrotic enteritis

We are happy to share with you the latest scientific manuscript co-authored by Dr Elinor McCartney published in Animal Science Journal.
The objective of the study was to assess the effects of a probiotic strain Clostridium butyricum MIYAIRI588 (CBM588) on broiler and weaned piglet health and zootechnical performance.
Five field studies were carried out in broilers and five in weaned piglets under European feed additive guidelines. Each study followed a randomized blocked design with two treatments: Control (basal diet) and CBM588 supplemented groups. The zootechnical performance parameters selected were body weight, daily gain, feed intake and feed efficiency (feed: gain). Broilers fed diets with CBM588 gained significantly more weight (+2%, p<0.001) and exhibited significantly better feed efficiency (1.6%, p<0.001) in comparison with Controls. Similarly, analysis of pooled data of weaned piglet trials showed that CBM588 – fed piglets were significantly heavier than Controls (+2.6%, p=0.014), exhibited significantly higher mean daily gain (+4.7%; p=0.004), and significantly improved feed efficiency (4.2%, p=.001). In addition to the zootechnical efficacy studies, the preventive effect of CBM588 on necrotic enteritis (NE) was assessed in a natural challenge model in broilers where CBM588 reduced the incidence and severity of NE lesions. These data indicate the potential of CBM588 to improve broiler and weaned piglet zootechnical performance, and to make a positive contribution to animal health.
