Increasing poultry product consumption trends have attracted researchers and development practitioners to look for interventions that transform the low-input low-output-based village chicken production to a high yielding production system. However, due to the intricate nature of the production system, there is a dearth of evidence that helps design comprehensive interventions at the smallholder level. Using national-level representative data collected from 3555 village chicken producers in Ethiopia, Nigeria, and Tanzania, this study examines the technical efficiency of village chicken production and investigates the main factors that explain the level of inefficiency. We applied a stochastic frontier analysis to simultaneously quantify the level of technical efficiency and identify factors associated with heterogeneity in inefficiency. We found that the level of technical efficiency is extremely low in the three countries, suggesting enormous opportunities to enhance productivity using available resources. The heterogeneity in technical efficiency is strongly associated with producers’ experience in breed improvements and flock management, limited technical knowledge and skills, limited access to institutions and markets, smaller flock size, gender disparities, and household livelihood orientation. We argue the need to adopt an integrated approach to enhance village producers’ productivity and transform the traditional subsistence-based production system into a commercially oriented semi-intensive production system.

Mathematical models 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.

Background Availability of appropriate genetics is important for the development of smallholder poultry (SHP). The biological potential of improved dual purpose chicken germplasms was evaluated in Nigeria. Methods A total of six breeds (Fulani, FUNAAB Alpha, Kuroiler, Noiler, Sasso, and Shika-Brown) were tested on-station, in deep litter houses at two test centres (Public and private facility) for 504 days. Birds were fed ad libitum for the first 140 days after which restricted feeding was practised. Result Lowest and highest hatchability of eggs set was 55% (FUNAAB Alpha) and 89% (Sasso), respectively. At 140 days, male live weights were 200%–300 % higher than the local chickens (975 g) except Shika-Brown (152%) and Fulani (135%). Lowest (p < 0.05) age at first egg was 119 days for Shika-Brown and 120 days for FUNAAB Alpha and Kuroiler. Highest hen-housed egg production was 192 for Shika-Brown, and feed intake per dozen eggs was lowest (p < 0.05) for Shika-Brown (2.9 kg) and FUNAAB Alpha (2.9 kg). Mortality rate of the locally sourced breeds (Fulani, FUNAAB Alpha, Noiler, and Shika-Brown) was significantly lower (p < 0.05) than the foreign-sourced breeds (Kuroiler, Sasso) during brooding, growing and laying. Conclusion Results from this study identified FUNAAB Alpha and Noiler as being more suitable for dual-purpose functions (egg and meat), while Sasso and Kuroiler (meat) and Shika-Brown (egg) were observed to be better suited for single purpose functions. These findings could guide the introduction of smallholder poultry-specific hybrid germplasms for the development of the smallholder poultry production systems in Nigeria.

Achaete-scute like-2 (ASCL2) gene is a maternally expressed gene that encodes a lineage-specific transcription factor that is essential for neurectoderm and trophectoderm development and is implicated in pre-natal and post-natal development in mammals. Using comparative genomics, various in silico sequence analyses were performed to characterize the putative imprinted ASCL2 gene. Additionally, tissue expression analysis between Angus, White Fulani, and N’Dama cattle breeds was conducted, as well as a molecular cloning of the gene transcript from bovine placenta. Four site-specific motifs were identified in the basic helix-loop-helix (bHLH) domain that are highly conserved in cattle, humans and mice. Pairwise comparisons of the coding sequence of cattle, human and mice revealed a dN/dS rate ratio that was significantly less than 1 (Z test). Two synonymous single nucleotide polymorphisms (SNPs) were found within 1 kb of the cloned complementary DNA (cDNA) in cattle. Bovine ASCL2 messenger RNA (mRNA) was relatively expressed in eight adult tissues with the ASCL2 gene differentially expressed in the muscle and skin tissues of the three cattle breeds. The conservation of these site-specific motifs for phosphorylation across the three species suggests a post-translational modification of the gene function and activity of the mammalian ASCL2 gene. Keywords: Cattle, imprinting, motifs, phosphorylation

Cattle are important livestock species with huge genetic resource for food security, agriculture and livelihoods. Over 60% of its genes are homologous to all mammalian species which creates a molecular basis for conducting comparative genomic analysis. Genomic imprinting has been implicated in a variety of biological functions and so identification of new or verification of known imprinted genes in livestock species is of high agricultural and biomedical importance. Fourteen (14) putative imprinted genes on bovine chromosome 29 (Bta 29) as well as the human (Hg 11) and mouse (Mm 7) orthologs were computationally characterized with respect to the CpG islands (CGI), transcription factor binding elements and sequence motif. Phylogenetic analysis was conducted across the three species for each of the genes identified to have promoter CGI. Promoter CGI were identified in ASCL2 , TSSC4 , CDKN1C , KCNQ1 , PHLDA2 and NAP1L4 . The promoter CGI were enriched with CpG containing transcription factor binding sites. Generally, it was observed that cattle was more closely related to human than mouse and that natural selection was the force driving the evolutionary change between the three species. Protein kinase motifs involved in phosphorylation were identified in the amino-acid sequences of ASCL2 , TSSC4 , PHLDA2 and NAP1L4 . Our results suggest the post-translation regulation of imprinting and that the predicted promoter CGI can be assayed to determine molecular function, gene expression and DNA methylation status of the bovine putative imprinted genes.
