| Summary: | 66% for meat and bone meal. Phosphorus availability from 88% for wheat. Digestible energy coefficients were high for absorb the nutrients in animal products more completely than at 79%. Data from this study indicate red drum can digest and availability is needed to more precisely formulate diets to availability of the following ingredients: select menhaden coefficients ranged from 59% for poultry by-product meal to conditions. The red drum is an emerging aquaculture species cottonseed meal, and wheat. Test diets consisting of a 70:30 determine apparent organic matter, protein, lipid, and gross digestible marker. Organic matter digestibility of energy coefficients for plant feedstuffs were considerably energy digestibility coefficients and apparent phosphorus fish may vary considerably, depending on a variety of factors fishmeal to 47% for wheat. Crude protein digestibility was fishmeal, regular-quality menhaden fishmeal, poultry by- for the digestibility trial, with chromic oxide as the non- for which information concerning nutrient and energy fraction increased, ranging between 94% for select menhaden free extract portion of plant products. These data provide high for most ingredients, ranging from 77% for regular including fish species, ingredient quality and processing ingredients generally decreased as the nitrogen-free extract lower, from 62% for wheat to 70% for cottonseed meal. meal to 95% for select menhaden fishmeal; however, digestible meet their requirements and to enable effective substitution menhaden fishmeal to 97% for wheat, with the exception of mixture of reference diet to test ingredient were utilized more precise information concerning nutrient and energy of available nutrients. of ingredients.
