The availability of sal seed meal (SSM), a byproduct of the sal seed fat industry in India, is of the order of 5 million tons per annum. Based on results of numerous feeding trials, recommendations have been made since 1967 for its extensive utilization as an ingredient of concentrate feeds for cattle, pigs and poultry. The DM of sal seeds contains 10-16% fat, 6-9% crude protein and 7-12% tannins. Fat extraction lowers the ether extract content of SSM to 4-8%.
