Peel meals as feed ingredients in poultry diets: Chemical composition, dietary recommendations and prospects

Abstract

The increase demand for poultry products has had direct effect on the supply and price of feed. This has increased research interest into the potential of locally available, less competed and low cost materials as feed ingredients. Several peels from roots/tubers and fruits have been evaluated in poultry diets but recommendations have not been consistent. High fibre, low nutrient density and likely presence of antinutritional factors limit the efficient utilisation of peel meal by poultry. Plant cultivar, age, agronomic practices, method of peel processing, breed and age of poultry all affect the inclusion level of peel meal in poultry diets. The increase interest in breeding crops for low antinutrients, knowledge in processing technologies and availability of several additives such as enzyme products, amino acids and antinutrients binding agents in the feed market could improve the usefulness of peel meal in on-farm poultry rations. This study reviews the potential of selected root/tuber and fruit peels as feed ingredients for poultry with regards their composition, dietary recommendation and prospects.

Evaluation of dried papaya pomace meal in laying hen diets

“…On dry matter basis, literature reports that papaya pomace contains a fairly high crude protein concentration (179–184 g/kg) and still quite some energy (17‐MJ gross energy/kg) (Martínez et al., 2010); (Rama Rao et al., 2006). In addition, papaya peel contains functional compounds including proteolytic enzymes (papain and chymopapain) and anthelmintic, antibacterial and anticoccidial compounds (Diarra, 2018); (Pavithra et al., 2018).…”

“…Data Badan Pusat Statistik (BPS, 2018) menunjukkan produksi pisang di Provinsi Nusa Tenggara Timur (NTT) tahun 2018 mencapai 92.988 ton/tahun. Koni, Bale-Therik, & Kale, (2013) ;Diarra, (2018) menyatakan bahwa kulit pisang mempunyai berat 25-40% dari berat buah pisang. Berdasarkan data ini maka diperkirakan sebanyak 23.…”

Performance and egg qualities of laying japanese quails fed yam peel meal based diets with enzymes complex+yeast supplementation

“…The incorporation of these alternative feedstuffs in poultry rations would help to mitigate the problem of feed shortages and extortionate prices resulting from seasonal production and high demand for traditional feedstuffs such as maize and soybean due to strong rivalry between humans, livestock and industries for their use (Agbabiaka, Madubuike, Ekenyem, & Esonu, 2013;Abd El-Hack, Alagawany, Farag, & Dhama, 2015). Thus, research interest in optimizing the use of fairly inexpensive and readily accessible agro by-products, such as yam peel to formulate poultry feeds, has been intensified in an attempt to minimize feed production costs (Edache, Yisa, & Okpala, 2012;Olajide, 2014;Aguihe, Kehinde, Ilaboya, Abidoye, & Iyayi, 2015;Diarra, 2018).…”

“…The peels have been reported to be integrated into poultry diets as a cheap untraditional and alternative feedstuff as a source of energy for partial replacement of corn, when properly processed to minimize inherent anti-nutritional factors (Akinmutimi & Onen, 2008;Ezieshi & Olomu, 2011;Edache et al, 2012). Nevertheless, higher amounts of crude fiber in form of non-starch polysaccharides (NSP) have been deemed a limiting factor for the use of yam peels by poultry birds (Abdel-Hafeez et al, 2018;Diarra, 2018). Accumulative data suggests that NSP has anti-nutritional activity in most monogastric species, such as poultry, because it is not readily degraded by digestive enzymes in poultry birds that disrupt gastrointestinal tract functions (Ravindran, 2013;Amerah, 2015, Aftab & Bedford, 2018.…”
