Nutritional assessment of banana (Musa paradisiaca) leaves and pseudostems for ruminants

Abstract : Banana entire plant is, in practice, one of the most important feed resources available for sustainable animal feeding systems in tropics. However, few data are available about the potential use that ruminants can make from its byproducts. This experiment was conducted in order to determine average chemical composition and to assess the nutritive value of banana leaves and pseudostems for ruminant nutrition. Fresh material was daily obtained and transported from a local banana plantation (nearly allocated to the experimental farm), manually chopped (3-4 cm piece size) and individually distributed into two equilibrated meals: 0800 and 1630. The trial lasted 21 d (14 d adaptation, 7 d data collection). Six adult castrated Pelibuey wethers (BW=33±1.9 kg) were used, randomly housed in individual metabolism crates and the INRA French system of ad libitum (10% of refusal from previous day) feed supply and total feces collection was implemented. The DM (20.0 and 6.5%) and CP (142 and 25 g/ kg DM) contents were considered acceptable and low for leaves and stems, respectively. The CF was relatively high (> 21%) in both plant fractions. It was noteworthy the high (2.5 mcal/ kg DM) ME of pseudostems; however, its low DM, CP and PDIMN affected voluntary intake, hence indicating that high DM (i.e. rice straw) and CP (i.e. forage legumes) feedstuffs are recommended as accompanying components in the diet. Future research opportunities exist for the optimum use of these highly available feed resources, focusing on basic strategic concepts like level of incorporation, productive purpose (milk?, meat?), physiological stage, among others.
