Abstract
The anti-aflatoxigenic potentials of the leaves ofPsidium guajava,Ficus benghalensis,Gardenia radicans,Punica granatumandZiziphus jujubaMill. were investigated. Poultry feed inoculated withAspergillus flavuswas treated with plant leaves powder and stored for the period of six months at 28 °C and 16% moisture level. At the end of each month, aflatoxin (AFT) concentrations were determined by high performance liquid chromatography. The proximate and mineral analysis was performed at the end of the storage period. Plant leaves control the AFTs (AFB1 and AFB2) efficiently without compromising the feed quality.Punica granatumleaves (5%) completely inhibited the AFTs in the stored feed over the period of six months.Ziziphus jujubeMill.,P. guajava,F. benghalensis, andG. radicansalso showed promising anti-aflatoxigenic activities. Results revealed that the AFT production byA. flavusin a stored poultry feed can be inhibited using the plant leaves under investigation.
Highlights
Poultry farming has gained importance throughout the world and has become a dynamic industry in South Asian countries since protein demand is increasing day by day (Mahesar et al 2010)

Summary
Poultry farming has gained importance throughout the world and has become a dynamic industry in South Asian countries since protein demand is increasing day by day (Mahesar et al 2010). Since the feed is used throughout the year, it is stored for months Factors such as prolonged storage, variation in temperatures, feed composition and storage conditions play an important role in the fungal growth which contaminates the feed (Stack and Carlson 2003; Iqbal et al 2015b). The use of medicinal plants to control AFTs is of great importance since these are safer in comparison to chemical or physical treatments (Volcani Center 2004; Shi et al 2006; Inan et al 2007; Asif 2015a,b,c,d,e,f; Adaramola et al 2016; Hamid et al 2016; Adaramola and Onigbinde 2017). The treatment efficiency was evaluated on the basis of AFT inhibition and nutritional value of the stored feed over the period of six months of storage
