This book was about feed formulation, the formulation of feed using a plant protein source to replace fish meal. Green peas or "garden peas," are the small, spherical seeds that come from pods produced by the Pisum sativum plant.They have been part of the human diet for hundreds of years, animal feeds and are consumed all over the world. Growing peas can be advantageous in many locations because they are easily harvested and are a valuable rotation crop for soil fertility in areas dominated by grains. E.g Canada is the largest producer of peas. It is also the largest exporter, with 40 percent of global pea exports. Largest use in Europe and north America in foods and largest use in Asia in feed industry and its also largest use in foods. The increased demand for fish meal, coupled with a significant shortage in global FM production, has created sharp competition for its use by the animal feed industry. Due to this reason that's make the feed to be expensive. The idea was to replace partially fish meal with green peas in order to reduce the price of feed in industry and also competition.
