The potential nutritive value of tomato by-products, both fruits and vegetative parts, was assessed by chemical analyses as well as by organic matter (OM) and crude protein (CP) in sacco degradability and in vitro organic matter digestibility. Tomato fruits contained 69g dry matter (DM) per kg fresh fruit and the average composition, per kg DM, was 923g OM, 28g ether extract (EE), 170g CP and 260g ash-free neutral detergent fibre (NDFom). Whole tomato plants contained 177g DM per kg fresh plant and their average composition, per kg DM, was 819g OM, 12g EE, 74g CP and 457g NDFom. Effective ruminal degradable and in vitro digestible OM content of tomato fruits were 534 and 583g/kg DM, respectively, and those of tomato plants were 274 and 474g/kg DM. Effective degradable CP content of tomato fruits and plants was, respectively, 33 and 20g/kg DM. Daily ingestion of fresh tomato fruits more than 1.5kg (about 100g DM) caused soft faeces in goats.
