1.2 AG187xxx Aquafeed formulation and feeding system 3(2-3-5)

Semester: August Course Objective: Feed plays a crucial role in fish production and production cost. High feed cost and insufficient protein sources in feed increase the demand for alternative protein sources. This course provides information about alternative protein sources, their digestibility, improving usability and quality of alternative feed stuffs by biotechnologies, using functional feed additives, feed formulation using software, and feed waste reduction. Learning Outcomes: On completion of this course, students will be able to: - identify suitable alternative feed ingredients - explore the local feed ingredients, biotechnology tools, functional feed

additive for improving feed - carry out assessment of digestibility and feed formulation - apply feeding methods suitable for aquaculture systems
