 PES is a processed and rich rice straw which is produced value added product to feed livestock in smallholder context. The processing improves digestibility and nutritional quality of rice straw to a great extent. It could immensely benefit smallholder farmers as feeding PES improves milk production to a great extent. It also benefits the environment because PES is expected to have less methane emission because of reduced NDF and saves land for pasture and grain crop cultivation. The process was developed by Ellery and got commercialized by Srinagar which is basically a feed company. Production of PES is scaled by Srinagar after analyzing the demand and cost benefit in two to three seasons.
