Parasitological investigation of dogs disposed off in nondescript abattoirs was carried out in two communities (Basawa and Angwagodo) in Zaria. Intestines from seventy (70) adult dogs were collected, and standard procedures were followed to determine their parasite loads. A total of sixty-three dogs (90.00%) were positive for different species of helminthes. The helminthes recovered were Dipylidium caninum, Taenia spp, Ancylostoma caninum and Toxocara canis. D. caninum was present in thirty five dogs (50.00%), Taenia spp in twenty dogs (28.57%). Ancylostoma caninum in twenty five dogs (35.71%) and Toxocara canis in four dogs (5.71%). There were no statistically significant associations between the location of study and frequency of recovery of each helminthes (P>0.05). Toxocara canis was only detected at Angwagodo. The mean worm load by location was higher at Angwagodo (24.59+55.03) than Basawa (8.66+9.44). The sex of the dog had no significant effect on the recovery of each helminthes (P>0.05). However, female dogs had a higher worm load (22.14+57.41) than the male dogs (12.12+18.44). The result of this study suggests that about 90% of the dog population in Zaria may be contributing to the contamination of the environment with eggs of zoonotic helminthes.

The study was to evaluate the effects of different processing methods on the proximate and anti-nutritional contents of Mucuna pruriens leaf meal. The Mucuna pruriens leaves were collected and processed by Air-dried Mucuna Leaf Meal (AMLM), Soaked Mucuna Leaf Meal in Cold Water (CMLM), Soaked Mucuna Leaf Meal in Hot Water (HMLM) and Fermented Mucuna Leaf Meal (FMLM). Proximate analysis showed that FMLM had the highest value (25.94±0.94%), while the lowest recorded in the CMLM (23.00±0.00%). The analysis of antinutritional factors showed that hydrocyanic acid, oxalate, phytate, saponin, reduced significantly (P<0.05) after processing the Mucuna Leaf Meal.
