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.
Poultry Specific Studies
|Type||Plant Part||Dosage||Specific use||Results||Ref|
|Chickens||16-30 ml/L drink, QD||Clinical Avian Medicine|
|Chickens||ground||anticoccidial||Fecal oocyst shedding decreased significantly in all of the treatment groups that were supplemented with Aloe vera as compared to the unsupplemented group. Furthermore, the Aloe vera-supplemented group showed significantly fewer intestinal lesions than the unsupplemented group following infection.||D Yim et al., 2011|
|Chickens||leaf extract||2 % in drinking water||Escherichia coli infection||The results showed improved growth, antioxidant activity, and immune response in A. vera-fed broilers.||M Kumari et al., 2023
|Chickens||extract||0.4% in drinking water||performance||When combined with licorice extract, helped reduce abdominal fat accumulation and had positive effects on broiler chicken performance. ||J Salary et al., 2014|
|Chickens||powder||5-7.5 g/kg of diet||overall health||The results suggested that dietary inclusion of 5 and 7.5 g/kg AV, similar with synbiotic supplementation, can be applied as effective alternatives to in-feed antibiotics for broiler diets. ||A Shokri et al., 2016|
