Abstract
For 14 days' adaptation and 10 days' collection, 20 Merinolandschaf wethers, 80-85 kg, were given cassava-barley straw diets with 19% soyabean meal, 39% round seeded peas (R08), 41% wrinkled peas (cv. Solara), 3.25% urea, or 52.4% cassava meal, 42.9% barley straw plus 5.25% urea. Wrinkled and round seeded peas contained 27% DM, 31% starch with 64.4% amylose (Solara) and 58% starch with 23.8% amylose (R08). From 30-38 kg until 38-45 kg, German Landrace X Pietrain barrows were given 1 kg of each of the pea varieties, for 9 days' adaptation and 7 days' collection. Digestibility of organic matter (DOM) was 89 and 93%, energy content was 793 and 823 st U/kg DM for round seeded and wrinkled peas, respectively. DOM was 90 and 94% in pigs; metabolizable energy was 15 and 16.5 MJ/kg DM for the round and wrinkled peas, respectively. Nitrogen balance was 32 and 28% due to low content of methionine and cystine. Based on these results, it is recommended that daily intake of the 2 varieties can be 3 and 1.5 kg for lactating cows and beef cattle, respectively. Mixed feeds for pigs up to 30% peas can be included.
