Ensilage of Jack bean and cowpea grains sole or mixed with sorghum to improve their nutritional value as feedstuff for growing-finishing pigs

Universität Rostock, 2015

Abstract: Under tropical conditions, Jack bean (JBN), cowpea (CWP) and sorghum (SOR) are alternatives for expensive feedstuffs for pig feeding. However, legume grains are difficult to ensile and their contents of anti-nutritional factors (ANF) hamper their use. Ensilage of JBN+SOR and CWP+SOR grain mixtures reduced the main ANF. Pre-ensiling methods (soaking and germination) and additives (lactic acid bacteria and molasses) furthermore improved ensilability. Compared to not ensiled grains, silages showed improved digestibility of essential amino acids and selected proximate nutrients in pigs.
