Abstract
Fusarium species were recovered from 23 out of 100 samples (23%) of equine
feeds collected from different farms and clubs in Cairo. The highest total Fusarium
count/g was obtained from the soya samples, however, the Fusarium colony counts
constituted the highest percentage of total fungal count in barley, while the lowest
Fusarium count was observed in corn. The incidence of Fusarium was the highest
in samples of yellow corn (58.33%), followed by soya, (35.7%) ; in barley ( 14.58
%) and hay (10%). Samples of pelleted feeds were all negative for Fusarium. A
total of 44 isolates of Fusarium were recovered from equine feeds. The isolates
were identified into 9 Fusarium species. The most common Fusarium species was
F. verticillioides (21 isolates), followed by F anthophilum. (9isolates), F
proliferatum and F’solani (4 each), and one isolate of each of Enygamai, F.
oxysporum, F’poae, F. dim erum and F sporotrichioides. Only one isolate was
recovered from hay, which was identified as F verticillioides. All the 21 tested
Fusarium isolates were fumonisin B 1 producers in amounts varying from 0.42 to
more than 21 ppm, in addition, all the corresponding feed samples were
contaminated with FB 1 in amounts varying from 1.4 ppm. to 40 ppm.
