    Dietary Oil Type and Late Feed Restriction Elicit Synergistic Effects on Growth, Caeca Bacteria, Carcass, Fat Accretion, and Muscle Lipids in Female Broilers
    (Wiley & Sons, Inc., 2023) Adeyemi, K.D.; Sola-Ojo, F.E.; El-Imam, A.M.; Atolani, O.; Alli, O.I.; Adegboyega, A.O.; Abubakar, S.O.; Obamonire, O.S.; Ologunade, F.O.
    The influence of dietary oil type (OT) and late feed restriction (FR) on growth, caeca bacteria count, carcass, separable fat depots, serum and muscle lipids, and meat quality in broilers is examined. In total, 224, 21-day-old female Arbor acres broilers are randomly allotted to either PN, Unrestricted+50 g kg−1 palm oil (PO); PR, 25%-FR+PO; SN, Unrestricted+50 g kg−1 soybean oil (SO); or SR, 25%-FR+SO for 21 d. The SN and PR birds have the heaviest and lightest body weight gain (BWG), respectively. Feed conversion ratio (FCR) is poorer in the PN birds. Feed-restricted birds have more caeca Lactobacillus and lower Salmonella, serum cholesterol, and triglycerides. Carcass yield is higher in SR birds and lower in PN birds. The FR-OT interaction is significant for muscle lipids and weight of fat depots. The PN birds deposit more abdominal, intramuscular, sartorial, mesentery and neck fats, muscle saturated fatty acids, and C18:1n-9 and lower C18:3n-3 and C20:5n-3 than other birds. Neither OT nor FR affects the pH, color, water holding capacity, and oxidative stability of breast meat. The changes elicited by 25%-FR on BWG, FCR, carcass yield, depot fats, and muscle lipids in female broilers are dependent on dietary OT. Practical Application: Fast growth rate and unrestricted access to feed can predispose broiler chickens to excessive fat accretion, which is counterproductive. Producing high-quality carcasses that meet consumers’ expectation is crucial for sustainable and efficient broiler production. The possible interaction between dietary OT and late quantitative FR in mitigating excessive fat accretion and altering production indices in female broilers is explored. Late quantitative FR reduces BWG, FCR, serum lipids, caeca pH and Salmonella spp. and fat accretion in fat depots, and enhances carcass yield and caeca Lactobacillus spp. However, the impacts are more pronounced in the PO birds than the SO birds. Late FR improves the C18:3n-3 and C18:2n-6 contents in PO meat while reducing the C14:0 and C16:0 contents in SO meat. These findings explicate that dietary OT and late quantitative FR can be synergistically used to mitigate excessive fat accretion and alter growth, caeca microflora, and muscle lipids in broilers.

    Effect of early feeding of diluted diets on haematology and serum chemistry of exotic and improved local chicks
    (Animal Science Association of Nigeria (ASAN), 2018) Sola-Ojo, F.E.; Alli, O.I.; Adeyemi, K.D.; Akinjuku, J.O.
    An experiment was conducted to evaluate the haematology and serum biochemistry of exotic and improved local chicks fed different diluted diets at early age (0 – 4 weeks). Two hundred (200) day old chicks (exotic and improved local genotype) were used for this study. The chicks were wing tagged and grouped at random based on genotypes to four dietary treatments. The diets were; commercial diets (CD) as Control, CD + 20% wheat offal (CDW), CD + 20% palm kernel cake (CDP) and CD + 20% processed baobab seed meal (CDB). At four weeks of age, blood samples were taken from the chicks for serum and haematological assay. The results indicated that packed cell volume, white blood cell, red blood cell, lymphocyte, neutrophil, monocyte, eosinophil and basophil were similar (p < 0.05) irrespective of the chicks’ genotype and across the dietary treatments. Significant (p < 0.05) variations existed in haemoglobin value between the strains and across the dietary treatment (2.45 to 8.80 x 106g/dl-1). Alanine aminotransferase and uric acid were not significantly influenced (p> 0.05) by genotypes and diets, but glucose, protein, albumin, cholesterol, alkaline phosphatase, aspartate aminotransferase, creatinine, high density lipoprotein, low density lipoprotein and triglycerol significantly (p < 0.05) varied. Dilution of chicks’ diets should be discouraged because it had a significant negative effect on haemoglobin and caused significant variations in chicks serum chemistry.

    HERITABILITY ESTIMATES FOR BODY WEIGHT IN PUREAND CROSSBRED NIGERIAN GOATS
    (National Animal Production Research Institute, Ahmadu Bello University., 2015) Yusuff, A.T.; Sola-Ojo, F.E.; Ojo, V.; Alli, O.I.; Fayeye, T.R.
    Forty does and eight bucks of West African Dwarf (WAD) and Red Sokoto goats were mated to produce pure and reciprocal crossbreds (WADxRSG, RSGxWAD) kids whose records were used to estimate heritability of body weight at birth, weaning and yearling stages. Heritability was estimated using variance components due to sire, dam and combine sire-dam effect. Crossbred WADxRSG was not significantly different (p>0.05) in birth weight from the purebred WAD (1.81 vs. 1.75 kg). Significantly (p<0.05) positive effect of crossbreeding was observed in the yearling weights of crossbreds. Estimates of heritability for weaning weight obtained for the purebreds (WAD and RSG) and WADxSRG cross were generally high (over 60%). Dams’ component heritability estimates were generally low (0.02 – 0.27) in RSGxWAD cross. Birth weight heritability estimates were low in pure WAD. Heritability estimates of yearling weight ranged from medium to high levels for all the methods of estimation except the dams’ components of the crossbreds. The results obtained in this study suggests that heritability estimates of body at different stages of growth is largely influenced by breeding group but sire components heritability should be given higher preference for genetic improvement of yearling weight of WAD and SRG.

    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.
