This experiment was conducted to investigate the effects of fungal treated oil palm fronds (FTOPF) on performance, carcass traits, meat quality, and muscle chemical composition.
Eighteen growing crossbred male goats (Thai Native×Anglo Nubian) with 18.7±2.0 kg of initial body weight (BW) were stratified and blocked by BW in a randomized complete block design. Three diets containing 30% of oil palm fronds (OPF) either untreated (UOPF) or treated with (FTOPF) with or without urea (FTOPFU) were used as roughage sources in total mixed rations (TMRs). The diets were offered and weight gain was determined. At the end of the experimental period, the harvest data and carcass characteristics of the goats were recorded, and muscular composition was determined.
No significant effect of fungal treated (FT) inclusion was observed in any of the feed intake, growth performance, and carcass characteristics. Likewise, no apparent effects on carcass composition and muscle chemical composition were detected in this study, except for hind leg and chump were affected (p<0.05) by FT inclusion.
In conclusion, feeding of fungal () treated oil palm frond in TMR diet did not affect performance and carcass characteristics in finishing goats.
本试验旨在研究真菌处理油棕叶（FTOPF）对生长性能、胴体性状、肉质和肌肉化学成分的影响。
选用18只初始体重（BW）为18.7±2.0 kg的生长杂交公山羊（泰国本地山羊×英努山羊），按体重进行分层并随机完全区组设计。三种日粮中含有30%的油棕叶（OPF），分别为未处理的油棕叶（UOPF）、经真菌处理的油棕叶（FTOPF）以及添加或不添加尿素的经真菌处理的油棕叶（FTOPFU），用作全混合日粮（TMR）中的粗饲料来源。提供日粮并测定体重增加情况。在试验期结束时，记录山羊的屠宰数据和胴体特征，并测定肌肉成分。
在任何采食量、生长性能和胴体特征方面，均未观察到添加真菌处理（FT）有显著影响。同样，本研究中未检测到对胴体组成和肌肉化学成分有明显影响，但后腿和臀部受添加真菌处理的影响（p<0.05）。
总之，在TMR日粮中饲喂经真菌处理的油棕叶对育肥山羊的生长性能和胴体特征没有影响。
