The objective of the present study was to evaluate the potential synergistic impact of the combination of fenugreek seeds (FS) and -based direct-fed microbials (DFM) on growth performance, intestinal health, and hematological parameters of broiler chickens.
A total of 160 one-day-old (Ross 308) broiler chicks were randomly assigned to a 2 × 2 factorial arrangement, with two levels of FS (0 and 5 g/kg) and two levels of -DFM (0 and 0.1 g/kg), with five replicates of 8 birds each.
The result showed that dietary supplementation of FS at 5 g/kg did not improve the growth performance of broilers but impaired the early growth performance by reducing body weight gain and increasing feed conversion ratio, which was recovered during finisher phase. Dietary supplementation of -based DFM at 0.1 g/kg did not affect the performance variables but increased the feed conversion ratio. The interaction of fenugreek seeds and -based DFM showed synergistic effects on growth performance during the later stages of production. However, antagonistic effects were observed on the blood parameters and the gut morphology.
This study demonstrated that FS and DFM had different effects on the broiler health and production depending on the phase of production. The interaction between FS and DFM revealed synergistic effects on growth performance during the finisher phase, but antagonistic effects on blood parameters and gut morphology. Further studies are needed to elucidate the underlying mechanisms and optimize the dosage and combination of FS and DFM for broiler health and production.
本研究的目的是评估胡芦巴籽（FS）与基于[具体物质]的直接投喂微生物（DFM）组合对肉鸡生长性能、肠道健康和血液学参数的潜在协同影响。
总共160只1日龄（罗斯308）肉鸡随机分配到2×2析因设计中，有两个FS水平（0和5克/千克）和两个基于[具体物质]的DFM水平（0和0.1克/千克），每个处理8只鸡，共5个重复。
结果表明，日粮中添加5克/千克FS并未改善肉鸡的生长性能，反而通过降低体重增加和提高饲料转化率损害了早期生长性能，不过在育肥期有所恢复。日粮中添加0.1克/千克基于[具体物质]的DFM对性能变量没有影响，但提高了饲料转化率。胡芦巴籽与基于[具体物质]的DFM的相互作用在生产后期对生长性能显示出协同效应。然而，在血液参数和肠道形态方面观察到拮抗作用。
本研究表明，FS和DFM对肉鸡健康和生产的影响因生产阶段而异。FS和DFM之间的相互作用在育肥期对生长性能显示出协同效应，但对血液参数和肠道形态有拮抗作用。需要进一步研究以阐明潜在机制，并优化FS和DFM的剂量及组合，以促进肉鸡健康和生产。
