Item Body weight and Morphometric traits characterization of Some Nigeria Homing Pigeons (Columbia livia).(Department of Biology. University of Tlemcen. Algeria., 2021) Abubakar, I.A.; Sola-Ojo, F.E.; Adeola, A.C.; Ibiwoye, D.I.Growth traits characterization of Nigeria homing pigeons was done using one hundred and thirty eight (138) birds from three locations (LCT) of different agro-ecological zones in Nigeria [Kebbi (KEB):North West; Ilorin (ILR): North Central and Osogbo (OSG): South West]. Parameters measured were body weight (BW) in gram and morphometric body parameters in cm viz. Head length (HL), beak length (BL), neck length (NL), body length (BL), body girth (BG), wing length (WL), body height (BH), thigh length (TL), drumstick length (DL) and keel length (KL). The results showed that, significant (p<0.05) differences existed between body weight and body parameters measured except BL. ILR pigeons had significantly (p<0.05) higher BW (263.51g) compared to OSG (204.15), but similar (p>0.05) to KEB (249.76g); the morphometric body parameters measured showed that HL, BG and WL values were significantly (p<0.05) higher in ILR; OSG had significantly (p<0.05) higher values for KL, while KEB pigeons had significantly (p<0.05) higher values for BL, NL, BH, TL, DL, and SL. Positive and significant correlations (p<0.01, 0.05) exists between locations, NL, SL and BH; BW was negatively correlated with locations with a significant (0.01) value of -0.58. PCA shows the clustering of growth traits from 18.94 to 25.14% under PC1 and 2, canonical discriminant functions gouped KEB and OSG with 56.60%; ILR and KEB with 43.60% while hierarchical clustering shows that KEB homing piegons are distinct from those of ILR and OSG. This results shows that locations have significant effects on growth traits in Nigeria homing pigeons.Item 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.Item 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 .
