The papaya is the fruit of the tree-like plant Carica papaya, of the plant family Caricaceae. C. papaya is native to the Americas and has a long history of its use in traditional medicines, for it's nutritional, digestive, and medicinal properties. Fresh, ripe papaya is one of the richest sources of vitamin C (even more than that found in oranges). It contains several unique protein-digesting proteolytic enzymes, including papain and chymopapain, and is also rich in iron and calcium; a good source of flavonoids (beta-carotene, lutein, zeaxanthin and cryptoxanthin), and vitamins A, B and G. Specific applications relating to poultry include:
  • Deworming: Papaya latex was shown to result in a 77.7% reduction in eggs per gram of droppings from chickens against Ascaridia galli and Cappilaria spp.
  • Antibacterial: Papaya seeds have been shown to be effective against Staphylococcus aureus, Bacillus cereus, Escherichia coli, Salmonella aureus, and Pseudomonas aeuroginosa.
  • Anticoccidial: Papaya is used for control of coccidiosis by farmers in the Jinja district in eastern Uganda, and local poultry producers in the Katanga province of the Domocratic Republic of Congo. A study conducted on 25 broiler chickens with coccidiosis confirmed the addition of 0.1-0.2% Azadirachta indica and Papaya in powder form added to the chickens' feed for 6 weeks was beneficial.
  • Antifungal: Adding papaya extract may help prevent the overabundance of Candida albicans, a yeast-like fungi known for causing sour crop.
  • Antiviral: Papaya is given to chickens suffering from Newcastle disease by farmers in the Jinja district in eastern Uganda. A decoction/cold water extract is prepared using the root and seeds.

Hensdried pomace meal5% dietegg productionImproved egg production and laying by 6.15% and 17% respectively, while it significantly decreased feed conversion ratio by 7.5%. Eggshell weight, thickness and strength of PP5 were higher than the control by 0.3 g, 0.8 mm and 0.43 kg/cm2, respectively. There was a significant improvement in albumin weight (by 1.5 g/L), albumin height (2.1 mm), yolk weight (0.4 g/L), yolk height (0.4 mm), yolk colour (4.4 points) and Haugh unit (8 points) due to PP5 treatment. Inclusion of papaya pomace at a level of 7.5% of layers diet had negative effect on Egg production, feed conversion ratio and interior and exterior egg quality traits. Inclusion of papaya pomace affected significantly serum total cholesterol, serum triglyceride, serum low density lipoprotein, serum high density lipoprotein, aspartate aminotransferase, alanine aminotransferase and white blood cell count. However, all blood traits of the experimental animals were within the normal ranges reported for layers. Inclusion of papaya pomace in 5% of layers commercial diets improves egg production and quality without negative impact on health while decreasing feeding cost.B Tamiru et al., 2021
