    ABSTRACT Mathematicalmodels provide valuable information for livestock improvement programmes. In this study, we evaluated the ability of five mathematical models (3P and 4P Gompertz, 3P and 4P logistic and neural network) to predict the growth of six tropically adapted dual purpose (TADP) chicken breeds (Fulani, FUNAAB Alpha, Kuroiler, Noiler, Sasso and Shika-Brown) under on-station and on-farm in Nigeria. Data for body weight were collected every 14 days from 1939 birds reared on-station, and every 28 days from 58,639 birds reared on-farm. Parameters used to evaluate the growth models were the adjusted coefficient of determination (AdjR2), Akaike’s information criterion (AIC), Bayesian information criterion (BIC) and root mean square error (RMSE). The AdjR2 for Gompertz 3P was higher than or equal to the AdjR2 for logistics 3P, Gompertz 4P and logistics 4P but was equal to or lower than the AdjR2 for the neural network (NN) for all TADP chickens raised on-station. Based on the goodness-of-fit criteria, Gompertz 3P had the best predictive values (AdjR2 = 0.989–0.998) for TADP chickens raised on-station, while logistic 3P was the best-fit model for TADP chickens raised on-farm. In conclusion, non-linear models and NN models yielded a good fit with the age-weight data of TADP chickens on-station and on-farm.

    Impact assessment of improved chicken genetics on livelihoods and food security of smallholder poultry farmers in Nigeria

    This study aimed at assessing the impact of the African Chicken Genetic Gains project on the livelihoods, and food security of smallholder poultry farmers in Nigeria. A total of 2,100 households were selected from 60 villages located in five states representing different agro-ecological zones: Kebbi (Sudan Savanna), Kwara (Southern Guinea Savanna), Nasarawa (Derived Savanna), Imo (Humid Forest) and Rivers (Forest Lowlands and Mangrove Swamp). Each household was randomly allocated an average of 30 birds from any one of the six improved chicken breeds (Fulani, FUNAAB Alpha, Kuroiler, Noiler, Sasso and ShikaBrown) tested on-farm. Baseline survey was conducted to provide a benchmark for both the on-farm test and post-on farm survey. For each of the surveys, structured questionnaires were developed, tested and administered using the Open Data Kit data collection tool pre-installed on Lenovo tablets (Model: Lenovo TAB 2 A7-30H). Data were subjected to inferential statistics (Chi-square test and Analysis of Variance). During the on-farm study, supplementary feed and vaccination services were provided for the birds, while the households received trainings on poultry management practices. Average household size was 7. Overall, the number of households consuming eggs increased by 50% (54% - 84%) while there was a 60% (47.7% - 76.5%) increase in the number of households eating chicken meat. The number of chickens consumed/household/month increased from 1 to 2, while the number of eggs consumed/household/week increased from 1 to 3. The results showed that average household monthly income from egg sales increased by 231% from N 3,020 ($ 14) to N 7,750 ($ 36) and when cocks were sold, N 8,400 ($ 39) was added to household income. Conclusively, daily monthly household income increased from N 475 ($ 2.2) to N 750 ($ 3.5) while egg and meat consumption increased by 200% and 100%, respectively. The impact on food security, and livelihoods was a result of the performance, and productivity of the improved, high producing chicken breeds introduced by African Chicken Genetic Gains in Nigeria.

    Production performance and survivability of six dual-purpose breeds of chicken under smallholder farmers’ management practices in Nigeria
    (Department of Animal Science, Nasarawa State University, Keffi., 2020-09-23) Yakubu, Abdulmojeed; Ajayi, Folasade Olubukola; Bamidele, Oladeji; Hassan, Waheed Akinola; Ogundu, Uduak; Alabi, Olayinka Olubunmi; Akinsola, Oludayo Michael; Sonaiya, Emmanuel Babafunso; Adebambo, Oluwafunmilayo Ayoka
    Abstract. Chickens kept under free-range, backyard or semi-intensive systems in the developing countries have more diverse use and benefits to rural households. Their use varies from region to region and from community to community within a region. The study investigated growth, laying performance and survivability of six improved dual-purpose breeds in five agroecologies of Nigeria represented by the following states: Kebbi (Sudan savanna/ northern Guinea savanna); Kwara (northern Guinea savanna/southern Guinea savanna); Nasarawa (southern Guinea savanna/derived savanna); Imo (lowland rainforest/swamp); and Rivers (freshwater swamp/mangrove swamp). On-farm data were obtained from 2100 smallholder poultry farmers that received an average of 30 birds (mixed sexes) of any one of the following dual-purpose breeds (Fulani, FUNAAB Alpha, Kuroiler, Noiler, Sasso and Shika-Brown) randomly allocated to them. The farmers used the backyard, scavenging system of management. Body weight and mortality records for cocks were taken for 18 weeks, while body weight, mortality, egg production and egg weight data were collected for hens up to 72 weeks. Compared with the local cocks (680 g), Kuroiler (1391 g), Sasso (1398 g) and Noiler (1461 g) had over 200% body weight at 18 weeks. Hen day egg production (HDEP) was higher in Shika-Brown (45.9%), FUNAAB Alpha (45.8%) and Kuroiler (45.7%) compared with the other breeds. Fulani, FUNAAB Alpha and Shika-Brown had higher survivabilities (p < 0:05) than Noiler, Sasso and Kuroiler. Ranking of the breeds for growth, laying performance and survivability was as follows: Shika-Brown/Sasso>FUNAAB Alpha/Noiler>Kuroiler>Fulani. The performance of the breeds was significantly (p < 0:05) influenced by the agroecologies. The cock body weights for Fulani (1121.1 g), FUNAAB Alpha (1502.4 g) and Noiler (1459.2 g) were highest in Kebbi, while for Kuroiler (1561.0 g), Sasso (1695.9 g) and Shika-Brown (1131.6 g) cock body weights were highest in Imo. Across the states, Imo had the highest HDEP (62.8%). Overall, the lowland rainforest/ freshwater swamp agroecologies supported the highest production performance of the breeds.
