Abstract

Torch ginger flower which functions as antibiotic and antioxidant is potential to be used as feed additive in ration to improve local duck production.  This study was aimed at assessing the effects of the inclusion of torch ginger flower solution in rations on the percentages of carcass and meat commercial cuts of male local ducks.  The study was conducted at Poultry Laboratory of Department of Animal Husbandry, Faculty of Agriculture, Djuanda University, Bogor from June to August 2016.  Twenty-four male local ducks aged 2 weeks with mean initial body weight of 450±70.35 g were used.  Ducks were fed basal rations containing 20–22% crude protein.    Torch ginger flower solution was included in the rations.  Ducks were allocated into battery cages of 150 x 40 cm each.  A completely randomized design with 4 treatments and 3 replicates was used.  Treatments consisted of commercial ration (PK) + 0% torch ginger flower solution (LBK) (R1), PK + 2.5% LBK (R2), PK + 5% LBK (R3), and PK + 7.5% LBK (R4).  Measurements were taken on the percentage of carcass and meat commercial cuts (wing, breast, back, thigh).  Data were subjected to an analysis of variance and a Duncan test.  Results showed that treatments gave significant effects (P<0.05) on carcass percentage but not on meat commercial cuts.  It was concluded that the inclusion of torch ginger flower solution in rations of up to 7.5% increased carcass percentage and tended to increase breast and thigh percentages.  It was suggested that the inclusion of torch ginger flower solution in rations be done by 5% to result in higher and more economical duck meat commercial cuts (breast and thigh). Key words: carcass percentage, commercial cuts, male local duck, torch ginger flower solution

卡卡斯的百分比和当地鸭的商业碎片在饲料中加入了棕熊的溶液
火把姜花具有抗菌和抗氧化的作用,有潜力作为饲料添加剂在日粮中用于提高地方鸭的产量。本研究旨在评估在口粮中添加火炬姜花溶液对公野鸭胴体和商业肉块比例的影响。该研究于2016年6月至8月在茂物大安达大学农学院畜牧系家禽实验室进行。试验选用24只2周龄、平均初始体重为450±70.35 g的公地鸭。饲粮中粗蛋白质含量为20 ~ 22%。在饲料中加入火炬姜花溶液。鸭子被分配到每个150 x 40 cm的电池笼中。试验采用完全随机设计,4个处理,3个重复。处理为:商品日粮(PK) + 0%姜花溶液(LBK) (R1)、PK + 2.5% LBK (R2)、PK + 5% LBK (R3)和PK + 7.5% LBK (R4)。测量了胴体和商业切肉(翅、胸、背、大腿)的百分比。数据进行方差分析和邓肯检验。结果表明,各处理对胴体率有显著影响(P<0.05),但对商业肉块无显著影响(P<0.05)。综上所述,在饲料中添加7.5%的火炬姜花溶液可提高胴体率,并有提高胸、大腿率的趋势。建议在饲料中加入5%的火炬姜花溶液,以获得更高和更经济的鸭肉商业块(胸肉和大腿肉)。关键词:胴体率,商品肉块,公土鸭,火炬姜花液
