Abstract
Higher inclusion levels of plant-based feedstuffs in diets for rainbow trout necessitate identification of methods to mitigate the negative effects on fish growth and health. Thus, an increasing number of novel and re-purposed dietary supplements are becoming commercially available to counteract the anti-nutritional effects of plant-based ingredients. Specifically, probiotic bacteria, which have previously been primarily investigated for their anti-pathogenic effects in fish, are now promoted to aid in the utilization of plant-based diets and digestive tract health. Additionally, dietary supplementation of commercially produced anti-inflammatory antibodies used to reduce gastrointestinal tract inflammation in terrestrial animals may also have potential to improve digestive tract health and performance of aquatic animals fed plant-based diets. The present paper describes two studies conducted at the Hagerman Fish Culture Experiment Station that investigated the ability of dietary probiotics and anti-phospholipase A2 antibody to improve performance of rainbow trout fed soybean meal-based diets.
