Introduction

After China, India is the second largest producer of peas (4 million tonnes/annum) in the world, contributing 22.9% to the world production (FAO, 2015). Pea pods are processed in the food processing industries, where pea pods are cut in a depodder and peas and empty pea pods (EPPs) are separated through rotating sieves. The EPPs constitute 50-55% of intact peas i.e. the recovery of green peas for human consumption is only 45-50%.

Feeding fresh empty pea pods

Fresh EPPs (Photo 1) contain 12-15% dry matter (DM), 18.5-20% crude protein (CP), 48-57% neutral detergent fiber (NDF), 43-52% neutral detergent solubles, 24-26% cellulose and 3.9-4.0% acid detergent lignin (ADL) on DM basis and are highly nutritious (Wadhwa et al., 2006; Bakshi and Wadhwa, 2013; Wadhwa and Bakshi, 2013; Bakshi et al., 2016).

The digestion kinetic parameters of DM assessed by the in sacco technique revealed that the EPPs had 82.3% degradable fractions and both effective and true degradabilities were 68?69%.

The EPPs or conventional green oat (Avena sativa) fodder supplemented with a mineral mixture and common salt were fed ad libitum to goat bucks (body weight 62.6 ± 1.1 kg) as a total mixed ration (TMR). The DM intake, digestibility of NDF and ADF, nitrogen-retention and metabolizable energy (ME) in the EPPs fed group were higher (P
