Over the last decades, the poultry industry has experienced steady growth. Although the industry is gradually expanding in Indonesia, poultry feed production has always been expensive. There is a need to study alternative ingredients to obtain affordable feed from natural resources. Chaetomorpha linum (CL) is an abundant macroalgae available throughout the year in Indonesia. This study aimed to determine the effect of CL on the histological structure of the small intestine, pectoralis muscle, growth performance, and meat quality of broilers.
This study used 300-day-old chick (DOC) male broilers that were reared until they were 21 days old. This study used a completely randomized design with four treatment groups and five replications, and each replication group contained 15 DOC individuals. The treatment groups consisted of Control (CON), CON basal feed (BF), CL1 (0.75%/kg BF), CL2 (1.5%/kg BF), and CL3 (3%/kg BF) groups. The histological structure of the small intestine, pectoralis muscle, growth performance, and meat quality of the broiler was examined.
Small intestine and pectoral muscle histomorphology, growth performance, and meat quality were significantly improved in the CL2 (1.5%) and CL3 (3%) groups compared with the CL1 (0.75%) and CON groups.
Dietary CL supplementation ameliorates small intestine and pectoral muscle histomorphology, growth performance, and meat quality of broilers.
在过去几十年中，家禽业经历了稳步增长。尽管该行业在印度尼西亚正逐渐扩张，但家禽饲料生产一直成本高昂。有必要研究替代成分，以便从自然资源中获取价格合理的饲料。扁浒苔是印度尼西亚全年都可获得的一种丰富的大型藻类。本研究旨在确定扁浒苔对肉鸡小肠、胸肌的组织结构、生长性能及肉质的影响。
本研究使用了300只1日龄雄性肉鸡，饲养至21日龄。本研究采用完全随机设计，分为四个处理组，每组重复五次，每个重复组包含15只1日龄个体。处理组包括对照组（CON）、对照组基础饲料（BF）、CL1（0.75%/千克BF）、CL2（1.5%/千克BF）和CL3（3%/千克BF）组。检测了肉鸡的小肠、胸肌的组织结构、生长性能及肉质。
与CL1（0.75%）组和对照组相比，CL2（1.5%）组和CL3（3%）组的小肠和胸肌组织形态学、生长性能及肉质均有显著改善。
日粮中添加扁浒苔可改善肉鸡的小肠和胸肌组织形态学、生长性能及肉质。
