Aloe vera has been used in folk and traditional medicine for over 2000 years. It contains several biologically active constituents, including mucopolysaccharides (glucomannans, polymannoses, about 10% of total solids), enzymes, anthranoids, lignin, saponins, vitamins, amino acids (almost 50% of the total amount consisting of 8 of the 10 essential amino acids) and minerals. Specific applications studied in poultry include:
  • Anticoccidial: Aloe vera has protective effects against Coccidiosis in chickens. Adding 0.1 to 0.5% aloe vera powder to the feed of broilers resulted in reduced fecal oocyst shedding compared to infected birds who did not receive supplemental aloe in their feed (Yim et al., 2011).
  • Intestinal health: Aloe vera can improve the intestinal microflora of chickens. Adding 1.5 to 2.5% in the feed of broilers lead to increased Lactobacillus count and decreased Escherichia coli count.
  • Immune enhancement: Adding 2% aloe vera gel to drinking water or feed (at 0.5 to 1%) showed a significant increase in antibody titer against Newcastle Disease Virus in a couple studies done involving broiler chickens.
  • Antibacterial: It can assist in inhibiting the growth of Staphylococcus aureus, E. coli, Pseudomonas aeruginosa, and Salmonella typhi.
  • Wound healing: Aloe vera gel is used topically to promote wound healing. Polysaccharides from aloe vera gel help to promote the proliferation of fibroblasts and production of hyaluronic acid and hydroxyproline, which are important components involved in extracellular matrix remodeling during wound healing.
