In vitro screening of two Nigerian medicinal plants (Vernonia amygdalina and Annona senegalensis) for anthelmintic activity.

Vernonia amygdalina and Annona senegalensis, two plants used by local/smallholder livestock farmers in Nigeria as anthelmintic were screened for in vitro anthelmintic activity using Haemonchus contortus eggs. The extract of V. amygdalina did not show any significant activity at concentrations up to 11.2mg/ml. The extract of A. senegalensis showed significant (P<0.001) reduction in egg hatch at a concentration of 7.1mg/ml. The in vitro fecal culture of eggs with A. senegalensis showed significant (P<0.001) reductions in larval recovery with increasing concentrations from 1 to 10% ((w/w) in fecal culture) when whole ground plant material was used. Although traditional veterinary healers and local livestock farmers claim both plants are effective as anthelmintics, our result indicate that only A. senegalensis showed promising anthelmintic activity especially with use of ground whole plant materials as used by some farmers.

Snakebites in poultry.

Eight cases of snakebite involving 5 flocks were seen in chickens, ducks and turkeys in the Avian Ambulatory Clinic of the Veterinary Teaching Hospital, Zaria, between July 1983 and August 1990. Most of the clients resided in areas with large canopies of trees and bushes. There was a large gully just behind the residential areas. Twenty-one birds were bitten; chickens constituted 85.7%, turkeys 12% and ducks 4.8% of this number. Hens incubating eggs were most vulnerable. Cocks were usually bitten when they attacked the snakes. Clinical signs were similar to those reported in other animal species. Gross lesions included congestion of visceral organs and hemorrhage in the viscera, around the bite sites and in the sc tissues. There was also im edema around bite sites. The fatality rate was 87.5%.

Challenge study on infectious bursal disease in chicks derived from vaccinated hens.

Presence and levels of maternal antibody (MA) in broiler chicks derived from hens vaccinated with a live infectious bursal disease (IBD) vaccine were investigated by a quantitative agar-gel precipitin test. At day old 100% of the chicks tested had MA; by 17 days of age it was present in only 10%. The mean MA level at day old was 337.5 UK units/ml but decreased to 6.3 UK units/ml at 17 days of age. Randomly selected chicks from the pool studied were challenged at weekly intervals from day old for 29 days with an IBD virus obtained from a natural outbreak. Subclinical and clinical disease were observed in chicks challenged at eight and 29 days of age respectively.

Campylobacter fetus subsp. jejuni in poultry reared under different management systems in Nigeria.

Cloacal swabs from 487 live birds in 36 flocks and 70 poultry carcasses were cultured for Campylobacter fetus subsp. jejuni. It was isolated from 12.3% of the birds in 19 flocks. Chickens, turkeys, and guinea fowl differed from one another in isolation rates of the organism. Management system affected its occurrence, and only 7.1% of eviscerated carcasses yielded it. It was concluded that bird species, management system, and immersing slaughtered poultry in boiling water before dressing affect recovery of C. fetus subsp. jejuni from live birds and carcasses.

Infectious bursal disease and spirochetosis in pullet chicks.

Infectious bursal disease and spirochetosis were diagnosed simultaneously in a flock of 100 six-week-old babcock pullet chicks. Larvae of the fowl tick Argas persicus were found on the bodies of the chicks. Thirty-nine of the chicks died 5 days after the onset of clinical signs.
