A cross sectional study was conducted in the dairy cattle of Al-Rodwan dairy project in Omdurman town during the three different seasons of the year. The results of the faecal examinations (n-290) showed that the prevalence of the internal parasites was 16, 8.42, and 7.36% for dry cool, dry hot, and wet hot season, respectively. The prevalence of coccidiosis was found to be 13, 4.21, and 2.10% for dry cool, dry hot, and wet hot season, respectively, while the prevalence of Fasciolosis was 1, 4.21, and 4.21% for dry cool, dry hot, and wet hot season, respectively. Statistically, no association between season and the prevalence of internal parasites (P> 0.05). A positive association (P< 0.01) between the milk yield and the occurrence of internal parasites was observed (infection with internal parasite reduce milk yield of the animal). Similarly, an association was recorded for the breed and age of the animal with infection of internal parasites (P< 0.05). Application of odds ratio (OR) indicated that breed was considered to be a protective factor (OR = 0.294), while age of the animal was considered to be a risk factor (OR = 3.638) for presence of internal parasites.
