  Background and Objectives: Monodora myristica and Ocimum gratissimum are herbs widely consumed for nutritional and medicinal purposes in developing countries including Nigeria. This study was therefore designed to assess the effects of M. myristica and O. gratissimum on sperm parameters, testicular and epididymal weight of albino rats. Materials and Methods: Forty-nine male Albino rats (170-200 g) were divided randomly into 7 groups (A-G) of 7 animals each. Rats in group A served as the control; groups B and C were given 300 and 500 mg kg–1 b.wt., of M. myristica, respectively; groups D and E received 300 and 500 mg kg–1 b.wt., of O. gratissimum, respectively; while groups F and G received 300 and 500 mg kg–1 b.wt., of M. myristica+ O. gratissimum, respectively. After 8 weeks of treatment, the animals were sacrificed and sperm samples collected for analysis. Results: Sperm analysis revealed that extract of M. myristica increased epididymal sperm motility, viability and count significantly (p<0.05) and dose dependently; whereas extract of O. gratissimum and the combined plant extract reduced sperm motility, viability and count significantly. Extract of O. gratissimuma lone increased sperm head abnormalities significantly. Conclusion: Findings of this study therefore, suggest that M. myristica promotes male fertility, whereas O. gratissimum and the combination of both herbs could have anti-fertility effects.

  Background and Objectives: Eggs are consumed globally and constitute an important part of man’s diet. High nutrient content, low caloric value and easy digestion make them valuable in many therapeutic diets. This study was designed to analyze the proximate, mineral and toxicant compositions of eggs of quail and chicken given aflatoxin contaminated feeds. Materials and Methods: Sixteen mature birds were randomly divided into 4 groups (1-4) of 4 birds each. Group 1 consisted of 2 broilers and 2 layers given uncontaminated feed. Group 2 consisted of 2 male and 2 female quails given uncontaminated feed. Group 3 consisted of 2 broilers and 2 layers given aflatoxin contaminated feed. Group 4 consisted of 2 male and 2 female quails given aflatoxin contaminated feed. Birds were fed for 12 weeks and 30 eggs from each group were weighed and analyzed. Results: It was observed that tannin, hydrogen cyanide, oxalate, phytate, fat and cholesterol levels were higher in chicken egg; while in quail egg iron, sodium, phosphorus, zinc and protein levels were higher. Eggs of quail given aflatoxin contaminated feed recorded elevated fat and cholesterol levels. Aflatoxin also reduced egg weight significantly (p<0.05). Conclusion: Findings of this study suggest that quail eggs are more nutritious than chicken eggs and aflatoxin is capable of reducing the quality of both egg types. Therefore, birds should be given aflatoxin-free feed.

  Background and Objective: Indigenous chickens as a source of meat and egg have made significant contributions to household food security throughout the developing world. The present study was aimed at evaluating the antibody titre of Nigerian chicken genotypes vaccinated with Salmonella and Newcastle vaccines. Materials and Methods: A total of 96 chickens were used for the study (24 normal feather, 24 frizzle feather, 24 naked neck, 24 exotic). Initial blood samples of the chicken were obtained from the wing vein and evaluated for Salmonella and Newcastle antibody titre using widal and haemagglutination inhibition test, respectively before vaccination. The birds were divided into two broad groups of 48 chickens each and treated with Salmonella and Newcastle vaccines, respectively. Blood samples were collected and analyzed at 3 and 5 days post vaccination. Results: Antibody titre was measured in the genotypes 3 days post vaccination with Salmonella vaccine as; 2.27 (frizzle feather), 2.14 (normal feather), 2.12 (naked neck) and 1.93 (exotic). The 3 days post vaccination titre with Newcastle vaccine were; 0.62 (Normal feather), 0.56 (frizzle feather), 0.51 (naked neck) and 0.09 (exotic). Responses to vaccination were significant (p<0.05) for antibody titre of the chicken vaccinated with Salmonella and Newcastle vaccines. The chickens showed significant responses to Salmonella vaccination and also, highest antibody titre was recorded in the birds 3 days post vaccination. Conclusion: It was concluded that frizzle and normal feather chicken genotypes showed more resistance to salmonella and Newcastle vaccines.
