    Effects of feeding diluted diets on growth performance and morpho-metric body parameters of exotic and improved local chicks
    (Nigerian Journal of Animal Science, 2020) Sola-Ojo, F.E.; Ayorinde, K.L.; Ifedayo-Ojo, B.O.; Adeniji, R.O.; Ibiwoye, D.I.; Abubakar, I.A.
    Two hundred chicks consisting of one hundred exotic layers and one hundred improved local chicks of local and exotic (LXE) genotypes were investigated to determine the effect of diet dilution on performance and growth traits of chicks for a period of twenty eight days. Standard chick’s diet was diluted with 20 percent wheat offal, palm kernel cake, baobab seed meal, respectively and fed to each chick’s type ad libitum throughout the trial period in a 2x4 factorial experimental design. Data collected included feed intake (FI), weight gain (WG), feed conversion ratio (FCR), body weight (BW) and morphometric body parameters such as body girth (BG), body length (BL), shank length (SL), shank diameter (SD), thigh length (TL), keel length (KL), wing length (WL) and drumstick (DL) and analyzed using one way analysis of variance of SAS statistical package. FI, WG, FCR, BW and all the morphometric body parameters were significantly (p<0.05) affected by genotype and diet dilution. Significant interaction existed between chicken genotypes and diets type for all the morphometric body parameters measured. Dilution of recommended diets should not be encouraged as the chicks fed diluted diets had poorer performance compared to those fed non-diluted standard diet during the experimental period. Therefore, small scale farmers are advised against such practice.

    Effects of Heterosis and Direction of Crossing on Production performance of F1 Offspring of Dominant Black Strain and Fulani Ecotype Chickens.
    (AGROSEARCH (A Journal of Agriculture Food and Development), Faculty of Agriculture University of Ilorin., 2012) Sola-Ojo, F.E.; Ayorinde, K.L.; Fayeye, T.R.; Toye, A.A.
    The objectives of this study were to determine the mode of gene action of determinants of performance (i.e. positive or negative heterosis) in F chickens produced by mating Fulani Ecotype (FE) and Dominant Black strain (DB) chickens, and whether the direction of crossing (DBxFE or FExDB) influenced the mode of gene action. Analysis of all F data irrespective of cross direction (combined) showed that the effect of 1 percentage heterosis was positive but weak for Weight Gain (WG) = 0.04, Feed Intake (FI) = 3.83, Body Weight at First egg (BWF) = 0.76, Egg Weight (EW) = 11.28, and 0 for Egg Number (EN) and Mortality (M) during the laying period. The combined heterotic effects were negative for Hen Day Production (HDP), Feed efficiency (FEf), Age at Sexual Maturity (ASM), and mortality from day old to 21 weeks of age (-0.16, -4.33, -9.15 and -67.74% respectively). Positive but low heterosis was obtained for BWF (0.76), and EW (11.28) and WG, FEf, EN, ASM, HDP and M showed negative heterosis (-100.00 to - 0.28) in the DBXFE cross bred. The mean performance of the FEXDB showed positive heterosis ranging from 1.08 to 100% in WG, FI, BWF, EW, EN, HDP and M during the laying period, while negative heterosis; -67.74, -4.54 and -8.22 was observed for M (0- 21days), FEf and ASM. The reciprocal effects showed F FEXDB were superior in ASM, 1 BWF and EW, while F DBxFE were superior in EN, HDP and M. 1

    Effects of plumage colour, sex and correlation on bodyweight and linear body measurements in the Nigerian local turkey
    (World’s Poultry Science Association-Nigeria Branch, 2016) Sola-Ojo, F.E.; Ayorinde, K.L.; Fayeye, T.R.; Ahutu, I.A.; Obadare, A.R.
    One hundred (100) sixteen (16) weeks old Nigerian local turkeys (55 males and 45 females) consisting of 43 lavender 36 white and 21 black plumage turkeys were used to evaluate the effect of plumage colour and sex on growth traits (body weight and linear body measurements). Correlations between body weight and the linear hody measurements were also evaluated. The black male turkey numerically had highest values for the growth traits measured, except the body length which was higher in the lavender, followed by the lavender male, while the white plumage turkey had the lowest value. In the female turkey, the lavender numerically had higher values for all parameters measured except the keel length which was higher in the black plumage turkey; the white female turkey had lowest value as well. The effect of sex on body weight and linear body measurements was significant (p<0.05). The male turkey had significantly (p<0.05) higher growth traits values than the female. Linear body measurements were highly correlated (p<0.01), positive and significant with body weight in Nigerian local turkey, ranging from 0.47 obtained for keel length to 0.95 for body length in male, and 0.60 obtained for keel length to 0.92 for body length in female. However, the shank diameter had a low (0.20) correlation value with the body weight in male Nigerian local turkey. This study shows that the black male and lavender female turkey had higher value for body weight and linear body measurement. Male Nigerian local turkey had significantly higher values for growth traits, while positive and significant correlation existed between some linear body measurements and body weight in the Nigerian local turkey.

    Evaluation of Reproductive Performance, Egg Production and Egg Quality Traits in the Fulani Ecotype Chicken Raised Intensively
    (Animal Science Association of Nigeria (ASAN)., 2011) Sola-Ojo, F.E.; Toye, A.A.; Ayorinde, K.L.
    Five hundred and ten (510) indigenous Fulani Ecotype (FE) chicken eggs collected from three different Fulani Kraals in Kwara state were used to evaluate the reproductive performance of intensively raised FE. The results revealed that 98.0, 79.2 and 65.8% were settable, fertile and hatchable, respectively. At 18 weeks of age, seventy two (72) adult females FE were housed singly in battery cages and evaluated for egg production from sexual maturity to 52 weeks in lay. The results showed that age at sexual maturity, body weight at first egg, total egg number and egg weight were 26 weeks, 1437g 128 and 44.11g, respectively. Clutch size ranged from 3-9, pause length ranged from 7-10days. Percentage hen housed production (HHP) was 53.10% while the percentage hen day production (HDP) was 57.6%. Age had significant (P<0.05) effect on some of the egg quality traits measured at 15, 30, 45 and 52 weeks in lay. Haugh Unit, Yolk Index, and Shell Thickness of FE eggs were above 80, 60 and 0.50, respectively. This study indicates the reproductive potentials of FE chicken that could be useful in developing an indigenous chicken with desirable egg production traits.

    Molecular Sexing and Taxonomic classification of Nigerian Guinea Fowl using Chromo Helicase DNA Binding Gene and 12S mitochondrial rRNA gene.
    (The Korean Society of Animal Breeding and Genomics., 2021) Sola-Ojo, F.E.; Afolabi-Balogun, N.B.; Adeniyi, C.A.; Adeyemi, K.D.; Ayorinde, K.L.; Alli, O.I.; Oni, O.A.; Okeke, C.U.; Momoh, E.O.; Adewara, J.; Abdulkareem, I.
    Sexing of birds at early age is very important for efficient selection and breeding; while characterization and taxonomic identification is relevant in conservation of birds’ genetic resources. This study used the genomic DNA of ten (10) guinea fowl keets to determine their sex using agarose gel electrophoresis and sequencing with chromo helicase DNA (CHD) binding genes, they were also characterize taxonomically using 12S rRNA mitochondria genes. The results of this study shows a double band (ZW) for females and a single band (W) for males under Agarose gel electrophoresis view, the Guinea fowl keets sequenced showed some deletions and were closer to Gallus_CHD12 in the phylogenetic tree. The Taxonomic classification result shows that the sequenced guineafowl keets were most related to the Numida meleagris 12S mitochondrial ribosomal RNA. This study corroborate the fact sex of guineafowl keet can be easily identified at genomic DNA level and they can be characterized taxonomically using the 12SrRNA mitochondrial genes.

    Relationship between egg weight, hatch weight and subsequent body weight in Fulani ecotype chicken
    (Department of Animal Sciences, University of Calabar., 2011) Sola-Ojo, F.E.; Toye, A. A.; Ayorinde, K.L.; Afolayan, O.F.
    Three hundred (300) Fulani Ecotype (FE) chicken eggs collected from free ranged Fulani Ecotype chicken were used to study the effect of egg weight on hatch weight and subsequent body weight. Eggs were grouped into two according to their weight (small and medium) and incubated. Body weight of the chicks was measured from the day of hatch to 12 weeks of age on weekly basis. Mean of the body weight gain from day old to 12 weeks of age in FE chicks obtained from small and medium egg size in this study were 306.73g and 311.36g, respectively. There was no significant correlations between egg weight, hatch weight and subsequent body weight in FE chicks obtained from small egg size, while a significantly (P<0.01) high and positively correlated relationship existed between hatch weight and egg weight of chicks obtained from medium egg size. Positive and significant inter-correlation (0.51 to 0.98) existed between body weight of FE chicks obtained from small and medium egg size. Linear regression equations showed a significant coefficient of determination for hatch weight, body weight at 2, 4, and 6 weeks using both small and medium egg weight values. The results of this findings indicated that both small and medium Fulani Ecotype eggs are settable. However, medium eggs produce larger chicks than the small eggs.

    Repeatability estimates of growth and egg production traits in the Fulani ecotype chicken
    (World Poultry Science Association-Nigeria Branch, 2014) Sola-Ojo, F.E.; Adedibu, Y.I.; Ayorinde, K.L.
    One hundred and eighty three Fulani Ecotype (FE) chicks hatched from FE eggs were used to estimate Repeatability (R) for growth and Egg production traits. Growth traits measured were Body weight (BW), Body length (BL), Body girth (BG), Wing length (WL), Drumstick length (DL), Keel length (KL), Thigh length (TL) Shank length (SL), Shank diameter (SD). Repeatability estimated was moderate for BW (050) from day old to 10 weeks age and high for BG (0.67) and DL (0.65). From 11 to 20 weeks age, high of 0.91 was estimated for BW, TL (0.69) and BG (0.68) while moderate repeatability estimates of 0.58 and 0.52 were obtained for shank length and shank diameter respectively. At the onset of lay, seventy two adults FE hens were randomly distributed into battery cage, and labelled per unit for egg production records. R was estimated for Egg weight (EW), Egg shell quality (ESQ), Yolk index (YI) and Haugh Unit (HU) at 30, 40, 50 and 60%. Hen Housed Production (HHP). R was moderate for HU and ESQ (0.43) at 30% HHP. At 40% HHP, ESQ had the highest R estimate (0.60), while EW and HU had 0.41. At 50% HHP, EW had R of 0.42, ESQ had 0.43, HU had 0.26. R estimate was highest for ESQ at 60 % HHP (0.48) followed by HU and EW (0.32). R estimated for YI were consistently low (0.01-0.16) throughout the HHP. R estimated in this study indicated the potential of FE chicken for genetic improvement.

    REPEATABILITY ESTIMATES OF SOME GROWTH TRAITS IN FOUR BROILER STRAINS AT DIFFERENT AGES
    (Nigerian Journal of Genetics, 2011) Sola-Ojo, F.E.; Ayorinde, K.L.
    A total of two hundred and eight (208) broiler clicks belonging in four strains (Anak 2000, Arbor Acre Ross and Shavers), were used to estimate repeatability of some growth traits of ages 2.4 and 6 weeks. The traits considered were Body weight, (BW), Body length, (BL) Body girth (BG), Drumstick Length (DL), Keel length, (KL) Shank length (SL) Shank diameter (SD) and Wing length (WL). Repeatability estimates of body weight were (0.99) for Anak 2000 and Arbor Acre at ages 2, 4, and 6 weeks. Shavers at 6 weeks and Russ at ages 4 and 6 weeks. It was (0.98) for Shavers at ages 2 and 4 weeks, and Ross at 2 weeks of age. Estimates obtained for other traits measured were highly repeatable ( > 0.60) across the strains. Medium repeatability estimate of 0.50 was obtained for shank length in Anak 2000 at 2 weeks of age while lower repediability estimates obtained were 0.45 and 0.32 for SL and SD in Arbor Aere at 4 weeks of age, 0.35 for shonk length and shank diameter and 0.43 for wing length in Shavers at 2 weeks. All the traits considered in the Ross strain were highly repeatable (> 0.83), indicating possible high expected response from selection for the traits.
