    (Nigerian Journal of Genetics, 2021) Sola-Ojo, F.E.; Adeola, C.A.; Yusuff, O.A.; Momoh, E.O.
    The analysis of Genetic diversity within and between populations is important for development of sustainable livestock production. Muscovy duck (Carina Moschata) is important among the poultry specie raised by most peasant farmers in Baruten local government area of Kwara State, Nigeria for egg and meat production. This study evaluated the genetic diversity between Muscovy duck populations in some selected locations within the local government; [Bani (BON), Okuta (OKE), Yembeleku (BART) and Ilesha Baruba (ILE)] using the nuclear DNA Cytochrome P450 family 2 Subfamily U Polypeptide 1 (CYP2U1) genes. The results showed 722 monomorphic sites and 25 polymorphic sites. The sequences obtained were grouped into nine haplotypes with diversity of 0.771 and low nucleotide diversity per site (Pi-0.00608). A total number of 26 mutations were discovered with haplotype diversity ranging from 0.80 to 0.86 for ILE, BART and BON Muscovy duck. The Jalview results from 0 to 167 bp revealed some of the polymorphism consisting of substitutions and insertions in BON, BART and ILE at 33, 37, 47, 113 and 159 bp; while the phylogenetic tree showed a high level of monophyletic relationship between some of the Muscovy duck. Our study reveals high haplotype diversity but low nucleotide diversity within and between the Muscovy duck studied in Baruten local government of Kwara State, Nigeria. The high haplotype diversity is in accordance with the high number of haplotypes observed in each location, while the low nucleotide diversity reflects that Nigeria Muscovy duck are likely a descent of common maternal lineage. This finding serves as baseline information, thus more research evidence including wider geographic coverage of Nigeria is still required.

    Effects of genotypes on Body weight and Morphometric body parameters in some adult Nigerian Local Chickens based on Normal and Rare feather types
    (The Korean Society of Animal Breeding and Genomics., 2020) Sola-Ojo, F.E.; Ibiwoye, D.I.; Asogwa, N.T.; Abubakar, I.A.; Yusuff, O.A.; Babalola, F.A.; Babatunde, A.O.
    Haemoglobin polymorphism in some adult local chickens of the North Central region of Nigeria was determined using cellulose acetate electrophoresis. Blood samples were collected from one hundred and eleven (111) local chickens. The chickens included 94 normal feathers and 7, 6 and 4, respectively for the rare feather gene types (frizzle; FF, silky; sh and Naked neck ; Nana). Genotype frequencies were calculated using simple descriptive statistics and subjected to Chi square analysis to determine how the observed distribution of haemoglobin types in the chickens fits with the expected. From the total number of observation the results showed that, 24.32, 43.24 and 32.43% of the population were HbAA, HbAB and HbBB, respectively. Eighty six (86) females and 25 males were studied and the frequencies of haemoglobin type were 22, 38 and 26 for Hb AA, Hb AB and Hb BB, respectively for the females while 20% of the male were Hb AA 40% were obtained for HbAB and HbBB . The normal feathered chickens had 21 Hb AA, 44Hb AB and 29 HbBB, the frizzle feather chickens had 3 Hb AA and Hb BB and 1 Hb AB, Silky feathers chickens in the population studied had 1 HbAA, 2 HbAB and 3 HbBB while Naked neck had 2 HbAA, 1 HbAB and 1 HbBB. The Chi square analysis results indicated that all the populations were of different haemoglobin type and distribution of observed frequencies fits into the expected with lower Chi test values obtained for all genotypes in the factors considered. Haemoglobin genotypes detected affected body weight, body girth, and beak length, while feather types affected body height and shank diameters among the population of chickens studied. This study indicated that the population of chickens with adaptive rare feather gene is low. Also, majority of the Nigerian local chickens studied had more of heterozygotes Hb AB and homozygotes recessive Hb BB haemoglobin type, thus concerted effort to conserve Nigerian local chickens with homozygote Hb AA haemoglobin type is recommended .

    Genetic diversity and relationship of Nigerian Muscovy duck populations
    (Korean Society of Animal Breeding and Genomics., 2021) Sola-Ojo, F.E.; Adeniyi, C.A.; Lameck, A.O.; Yusuff, O.A.; Momoh, E.O.; Adekoya, A.R.; Adedibu, I.I.
    Muscovy duck (Caraina Moschata) is an economically important species due its unique meat taste and low-caloric content. It is one of the domestic poultry species in Nigeria as it ensures food security to the rural sectors. Rearing of Muscovy is concentrated in some part of the country due to its peculiar nature as water loving poultry species and peoples belief. In this study, we analyzed the genetic diversity and relationship of Muscovy duck populations collected from 15 different locations where Muscovy duck lovers resides in four states (Kaduna, Kwara, Niger and Oyo) of Nigeria based on Nuclear DNA Cytochrome P450 Family 2 Subfamily U Member 1 (CYP2U1) gene. A total of 48 polymorphic sites consisting of substitutions with 33 singletons variables was observed. The 82 sequences were assigned into 32 distinct haplotypes. Haplotype diversity was 0.7925. The Phylogenetic analysis showed close clustering across all locations with the exception of BART 495, PAT 35 and KEY 764 individuals. The maternal genetic structure likely suggests the extensive genetic intermixing within the country. In addition, the differentiation of BART 495, PAT 35 and KEY 764 may be due to a certain demographic history and/or artificial selection that shaped its haplotype profile. The current data on Nigerian Muscovy duck genetic diversity based on nuclear DNA CYP2U1 gene do not permit us to make further conclusions; therefore, more research evidence from genetics and archaeology is still required.

    Phenotypic, Physiological and Blood Profile Characterization of Muscovy Ducks (Cairina moschata) In North Central Nigeria
    (Department of Biology. University of Tlemcen. Algeria., 2020) Sola-Ojo, F.E.; Adeniyi, C.A.; Yusuff, O.A.; Abiola, J.
    Animal genetic resources (AnGR) are important to all future developments and adaptations. The concept has an international obligation to conserve certain characteristics of domestic animals for sustainable and future use. Characterization of indigenous Muscovy duck (Cairina moschata) would provide information for AnGR and also aid in conservation of ducks for future use. Two hundred (200) Muscovy ducks obtained from five (5) geographical locations in North central Nigeria were characterised using qualitative traits, physiological parameters, blood profile and quantitative traits. The results showed that 52.50, 54.00, 51.50, 50.00, 45.00 and 35.50% of the Muscovy ducks in the study area had black colour with respect to their general body plumage, shank, bill, web, eye, and bean, respectively. 50.00% were of horizontal body carriage, 90.50% had palmate web type, and 95.00% had no crest while 62.50% had caruncles. Sexual dimorphism existed between male and female with drakes having significantly (p<0.05) higher values compared to ducks in all the quantitative traits measured. Physiological parameters were not significantly (p>0.05) different according to sex and origin of the Muscovy duck studied. Comparison of the ducks by origin showed significant (p>0.05) differences in body weight, shank diameter, keel and wing length, and also in white blood cells, lymphocytes, red blood cells and mean corpuscular haemoglobin concentration, platelets and glucose. The information obtained here can serve as a guide on decisions concerning the conservation and development of selective breeding strategies for improvement of Muscovy ducks in the studied area.
