Turkeys were mostly infested by Stomoxys calcitrans (74.5%) during the day and by Culex pipiens (15.0%) at night. Plasmodium sp (5.8%) and Haemoproteus (0.1%) were transmitted by these species of flies. Other arthropods identified infesting turkeys included Haematobium sp (3.5%), Simulium sp (2.0%), Aedes sp (1.0%), Culicoides sp (0.2%) and the biting lice Menacanthus stramineus (2.5%). The most common fly species recorded around chickens were the non-biting fly Musca domestica (60.5%) during the day, and Culex pipiens (15.5%) at night. Infesting lice were M. stramineus (17.0%) and oniodes gigas (3.0%). Culicoides sp represented only 1.0% of infestation. Plasmodium sp (2.4%) was the only haemoparasite seen in blood samples examined from chicken. Pigeons were mainly infested by Pseudolynchia canariensis (85.8%) by day and Culex pipiens (12.5%) at night. M. domestica represented only 1.7%. Haemoparasites identified from the blood samples of pigeons were Haemoproteus sp (2.2%) and Plasmodium sp (0.8%). M. domestica (95.0%) and Drosophila melanogaster (5.0%) were the only flies caught around ducks. Both flies are not blood-sucking. No haemoparasite was identified from the blood samples examined. The blood sucking activity of these parasites resulted in irritation and the development of anaemia, leading to production losses due to morbidity and mortality.

Seven day old broiler chicks of the Nera breed were allotted to 5 dietary treatments with 3 replicates at 6 birds per replicate. Diet A was the control and contained 23.14% crude protein with fishmeal constituting 5% of the diet and no yeast additive. Diet B served as a basal diet containing 18% crude protein with no fish meal and no yeast additive. Diets C, D and E had the same formulation as diet B but with 0.08 %, 0.16% and 0.32% of yeast (Yea-sacc 1026(P) respectively. Average voluntary feed intake values (66-74gd -1 ) were similar (P>0.05) but greater than 47.7 gd -1 for birds on basal diets (P 0.05). This study reinforced the potential and efficacy of Yea-sacc 1026(P) Yeast culture as a growth promoter in low protein diets for broiler chicks. Yea-sacc 1026(P) improved feed intake and feed efficiency in a low protein diet with appreciable contribution to enhancing carcass characteristics and organ weights at an optimum level of 0.08% dietary inclusion.

The analysis of serum biochemical parameters such as alanine aminotransferase (ALT), aspartate amino -transferase (AST), alkaline phosphate (ALP) bilirubin, total protein (TP), albumin (ALB) and triglycerides (TGC) of the rats treated with Urena lobata Cleome viscosa did not show any significant increase in the parameters except the blood urea nitrogen (BUN) of the rats. The BUN and GGT of the rats administered with Hyptis suaveolens were increased significantly (P Cleome viscosa showed kidneys with generalized nephrosis of the tubular epithelial cells, lungs with severe emphysema and adrenal gland with hemosiderosis, thus the effect of Cleome viscosa may mean it is nephrotoxic. The organs of the rats treated with Hyptis suaveolens showed liver with peri-hepatic accumulation of proteineous material, kidneys with diffused area of nephrosis of tubular epithelial cells. These observations along with the increases in BUN, and GGT produced by extracts of Hyptis suaveolens may suggest that the plant is hepatotoxic and nephrotoxic in rats.

High levels of Mn (189 and 465 ppm), Cu (30.5 and 21.8 ppm), Zn (151.9 and 75.1 ppm), and NO 3 (4,600 and 7,200ppm) were found in the leaves of E. hirta and P. amarus respectively. No traces of cyanide and nitrite were found in the leaves of these two plants. Varying proportions of Fe (2,225 and 1,563ppm), Mg (5,500 and 5,800ppm), K (33,000 and 32,000ppm), Ca (21,000 and 26,500ppm), and Na (558.1 and 125 ppm) were found in the leaves of E. hirta and P. amarus respectively. The levels of chemicals are high enough to constitute a source of toxicosis to animals consuming them and their use for medicinal purpose should also be a source for concern most especially if the fresh leave decoctions are used.

The results showed that the guinea pig erythrocytes, were associated with the same HA titre (8 log 2); with HA times being 30, 50 and 35 minutes respectively and elusion times were 120, 85 and 105 minutes respectively. The data therefore established biometric and qualitative similarities between the control and these two test dilutions of erythrocytes. In HI tests on sera from commercial poultry, the guinea pig indicator was consistently associated with 2 to 5 fold higher HI titres than the other indicators in some of the flocks tested. A retrospective flock health analysis revealed that the higher titres were associated with confirmable Newcastle Disease (ND) outbreaks in the affected flocks. These findings therefore suggested that the use of standardised guinea pig erythrocytes in parallel with chicken erythrocytes as indicators, might facilitate field ND diagnosis and thus obviate the problem posed by the delay in the requirement for paired sera from acute and convalescent phases of outbreaks in vaccinated flocks, as in existing procedure. The generally recognised simplicity and economy of HI serology would continue to favour its application in preference to other laborious and complicated virologic techniques, especially in medium scale laboratories, as well as in rural developmental and epidemiologic studies.
