Abstract: A study was undertaken to predict the correlation between egg weight and egg characteristics in quail. Data was collected on 102 eggs collected from female quails at 28 weeks. Eggs were numbered, weighed and classified into six egg weight groups: below 9.0g, 9.0-9.5g, 9.6-10.0g, 10.1-10.5g, 10.6-11.0g, and above 11g group. There were 17 eggs per egg weight group. Data was collected on egg weight, shell weight, shell ratio, albumen height, albumen weight, albumen ratio, albumen index, yolk height, yolk diameter, yolk weight, yolk ratio and Haugh Unit. Data collected were analysed using the General Linear Model (GLM) procedure of the Genstat edition 11. The correlation between the various characteristics of egg were determined. The result shows that Albumen diameter, albumen length and albumen width were influenced by size of egg (p<0.05). Albumen diameter and albumen length increases with increasing egg size. There was a positive correlation between egg length and albumen (0.448), albumen diameter (0.463), shell surface area (p<0.01). Egg width, height, shape index, shell ratio and shell surface area were significantly (p>0.05) influenced by the sizes of quail eggs. The egg sizes of above 11g had the best egg length followed by 10.6g-11.0g, 10.1g-10.5g, 9.6g-10.5g, 9.0g-9.5g and below 9.0 g had the least egg length indicating a direct relationship between egg length and egg weight. The positive correlations between the internal and external egg quality traits indicated that the traits can be improved through selection.

Abstract: This study aimed to determine the seroprevalence of Newcastle disease (ND) among some local poultry species from live bird markets (LBM) and households in Makurdi Benue State, Nigeria. A total of 543 (300 local chickens, 199 pigeons and 44 ducks) sera samples were collected between October 2018 to April 2019. Sera samples were tested using Haemagglutination inhibition HI) test. The overall seroprevalence of Newcastle disease virus (NDV) antibodies was 9.9% (54/543). The prevalence of antibodies to ND was found to be higher in ducks 20.5% (9/44), followed by local chickens 10% (30/300) and pigeons 7.5% (15/199) respectively. There was statistical significant association (P = 0.000817) between location of sampling of local poultry and seropositivity for ND. Also there was a statistical significant association (P = 0.0348) between species of local poultry and ND antibody titre. This study revealed that local chickens, ducks and pigeons in Makurdi could play significant role in the epidemiology and transmission of ND to susceptible commercial exotic birds or other local poultry species especially when reared in close proximity. The study concluded that the prevalence of ND antibodies indicated the presence of the virus among the population and ducks and pigeons could be reservoirs and carriers for NDV. Vaccination campaign should be organized for local poultry species for the control of ND in the study area.

Abstract: The study assessed the productive performance of adult indigenous chicken from four Nigerian states of the North Central Zone namely; Nasarawa, Niger, Benue, Kogi and the Federal Capital Territory (FCT). Data were collected at both Out and On-station. The result showed that flock structure was in proportion of 28, 21.4, 23.2 and 27.5% for cock, hen, growers and chicks. Chi-square showed significant difference (P<0.001) by state. Clutch size ranged from 10.84±0.23 to 11.45±0.23 in FCT and Nasarawa state. On-station clutchsize was 13.11±0.23. There was significant difference (P<0.001) by site while state has similar values. Age at first egg, clutch number and hatchability did not vary significantly. However, there was significant difference (P<0.05) in Chick mortality which ranged from 43.19 to 53.89% in Benue and the FCT. On-stationmortality was 26.78%. Correlation coefficient between egg and production traits showed that most correlation traits were significant at 1%. Only number of chicks hatched, egg wasted, egg width and length and mortality were correlated at 5%. Some common diseases showed that Newcastle is the most prevalent 63.22%. Farmers attached a high preference to keeping male chicken for sale rather than breeding purposes. The high hatchability is an indication of good reproductive performance in the chickens of the study area. Improvement in management practices and vaccination against Newcastle disease should be adopted to curtail its devastating effect on indigenous chicken production in the study area.

Abstract: The growth performance, carcass qualities, organs weight and haematology of ninety-six (96) day-old Agritech broiler birds fed Turmeric powder additive were evaluated. The birds were reared on deep litter system and were randomly allotted to four (4) treatments of graded dietary levels (0, 1.5, 3.0 and 4.5%) of Turmeric powder denoted as; T1, T2, T3 and T4 respectively. Each treatment with 24 birds was also replicated thrice with 8 birds per replicate in a Completely randomized design for 56 days. Performance indicators measured included feed intake, body weight gain, feed conversion ratio, carcass and organ weights and haematological parameters. Results showed that turmeric additive elicited significant differences (P ≤ 0.05) across treatments. Bodyweight gain (2113.00g) and feed conversion ratio (2.02) were significantly higher in broilers fed diets with 1.5% turmeric powder (T2) than those on other treatments. Turmeric additive also improved the carcass and organ weights as well as the haematological parameters in which the erythrocytic and leukocytic counts were not significantly different (P ≥ 0.05) in T2, T3 and T4 except for the control. However, the overall positive effect of turmeric powder in broiler diet was observed in T2 (1.5%) following improved feed intake, body weight gain and feed conversion ratio and this inclusion level is advocated while further research in other avian species available in warm wet regions of Nigeria is suggested.
