Cinnamon (Cinnamomum verum, also referred to as Cinnamomum zeylanicum (CZ) or "true cinnamon") is a common herb used by several cultures worldwide. The main active chemicals in cinnamon are: trans-cinnamaldhyde (found in the bark), eugenol (present in the leaves) and camphor (found in the root). Specific applications in relation to poultry include:

Antibacterial: Cinnamon has been shown to inhibit the growth of numerous types of bacteria, including: Avibacterium paragallinarum, Clostridium spp, Enterobacter spp, Enterococcus spp, Escherichia coli, Klebsiella pneumonia, Listeria monocytogenes, Pasteurella multocida, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella spp, Staphylococcus spp, Streptococcus spp and Yersinia spp.
Antifungal: Cinnamon has also been shown to inhibit activity against numerous fungi, including: Aspergillus spp, Candida albicans, and Microsporum spp.
Red poultry mite repellent: Cinnamon was found to be a semi-effective repellent against red poultry mites.
Gastrointestinal Tract Benefits: Cinnamon powder or its derivatives have positive impacts regarding growth curve, digestion, absorption, activity of gut microbiota, immunity, as well as improved feed utilization.

Poultry Specific Studies

Type	Plant Part	Dosage	Specific use	Results	Ref
Quail		800 mg/kg diet	immunity	can be used to improve the laying Japanese quail performance, egg quality, and immunity.	W Dosoky et al., 2021
Broilers	bark powder	2000 mg/kg diet	growth promoter	can be applied as an alternative to in-feed antibiotics for broiler starter diet.	M Qaid et al., 2021
Chickens	bark oil		immunity	increased immune response in broiler chickens. CNO lowered precaecal Escherichia coli and tended to lower Clostridium spp. counts. The villi height in the duodenum and jejunum was increased by CNO. Dietary CNO increased the superoxide dismutase activity in serum.	S Chowdhury et al., 2018
Chickens		6 g/kg diet	anticoccidial, coccidiosis	moderately reduced coccidiosis and attempted to improved bodyweight, feed conversion ratio, and production efficiency	M Qaid et al., 2020
Chickens	oil extract	0.005-0.02% diet	antifungal, aflatoxicosis	Results suggest the potential use as a feed additive to control mycotoxin contamination in poultry feed.	H Yin et al., 2015
Broilers		0.06% in drinking water	antibacterial, Salmonella	effective in killing Salmonella Enteritidis and C. jejuni in chicken drinking water and may decrease the likelihood that water will contribute to colonization of chickens by these pathogens.	A Johny et al., 2008
Chickens	powder	5 g/L in drinking water	immunity	Higher antibody titer against NDV	Sadeghi et al., 2018
Chickens	powder	4-8 g/kg diet	immunity	Higher lymphocytes proportion	Najafi and Taherpour 2018
Chickens	oil extract	100 -200 ppm diet	immunity	Lowered H/L ratio, higher white blood cells	Al-Kassie et al., 2018
Broilers	powder	1.0% of diet	immunity	As effective as oxytetracycline as a preventative growth promoter when added to the diet.	Khanzada Khan and Nazir Ahmad 2022
