The main objective of the present work was to determine the nutritional value and the strategies of using green banana meal (BM) in growing pigs. Two trials involving a total of 96 growing pigs were designed to study the effect of the harvest stage on the nutritional and energy values of BM (trial 1) and to evaluate the consequence of feeding gradual levels of BM on growth performance and feeding behavior in growing pigs (trial 2). In trial 1, the digestive utilization of three diets including 40% BM were compared with a control (C) soybean meal-corn diet in two batches of 12 pigs. BM was obtained from fruits harvested at 750 degrees-days (DD; early harvesting stage), 900 DD (normal harvesting stage) and 1150 DD (late harvesting stage). In trial 2, 72 Large White pigs were grouped in pens of nine animals and were given ad libitum access to one of the four dietary treatments (two pens/diet) differing from the rate of inclusion of 900 DD BM (0%, 20%, 40%, 60%). The estimated energy apparent digestibility coefficients of BM increased with the harvest stage (75.5%, 80.7% and 83.2% for BM at 750, 900 and 1150 DD, respectively). Digestible energy and metabolizable energy values were higher for BM at 1150 DD (13.56 and 13.05 MJ/kg DM, respectively) than at 900 DD (13.11 and 12.75 MJ/kg DM, respectively) or at 750 DD (12.00 and 11.75 MJ/kg DM, respectively). In trial 2, average daily gain and feed conversion ratio were not affected (P>0.05) by the rate of BM inclusion (822 g/day and 2.75 kg/kg on average, respectively). Feed intake and feeding behavior parameters were not significantly influenced by the dietary treatments except for the rate of feed ingestion with a lower value for the diet with 40% of BM (27.4 v. 32.2 g/min on average; P<0.01) when compared with the other diets. Results of this study indicate that the energy value of BM increases with the harvest stage and that BM can be incorporated up to 60% in growing finishing pig diets.
本研究的主要目的是确定绿色香蕉粉（BM）在生长猪中的营养价值及使用策略。设计了两项试验，共涉及96头生长猪，以研究收获阶段对BM营养和能量值的影响（试验1），并评估在生长猪日粮中逐步增加BM水平对其生长性能和采食行为的影响（试验2）。在试验1中，将含40%BM的三种日粮的消化利用率与对照（C）豆粕-玉米日粮进行比较，试验分两批进行，每批12头猪。BM取自750度日（DD，早期收获阶段）、900 DD（正常收获阶段）和1150 DD（晚期收获阶段）收获的果实。在试验2中，将72头大白猪按每栏9头分组，自由采食四种日粮处理之一（每种日粮2栏），日粮中900 DD BM的添加比例不同（0%、20%、40%、60%）。BM的能量表观消化率系数随收获阶段增加（750、900和1150 DD的BM分别为75.5%、80.7%和83.2%）。1150 DD的BM的消化能和代谢能值（分别为13.56和13.05 MJ/kg干物质）高于900 DD（分别为13.11和12.75 MJ/kg干物质）或750 DD（分别为12.00和11.75 MJ/kg干物质）。在试验2中，平均日增重和饲料转化率不受BM添加比例的影响（P>0.05）（平均分别为822 g/天和2.75 kg/kg）。除采食速度外，日粮处理对采食量和采食行为参数无显著影响，与其他日粮相比，含40%BM的日粮采食速度较低（平均为27.4对32.2 g/分钟；P<0.01）。本研究结果表明，BM的能量值随收获阶段增加，且在生长育肥猪日粮中BM添加比例可达60%。
