    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.

    Nutrigenetic Effect of Moringa oleifera Seed Meal on the Biological Growth Programme of Young Broiler Chickens.
    (AGROSEARCH (A journal of Agriculture Food and Development), Faculty of Agriculture University of Ilorin., 2013) Toye, A.A.; Sola-Ojo, F.E.; Olaniyan, O. M.; Ojo, V.
    A Nutrigenetic study of the effects of graded levels (0%, 5% and 10%) of undecorticated undefatted Moringa oleifera Seed Meal (UUMOSM) on the biological growth programme of 48 young broilers of two genotypes (Marshall and Arbor Acres) was conducted. Rates of change (%) of Body Weight (WTR), Length (BLR) and Girth (BGR), and Lengths of Shank (SLR), Thigh (TLR), Wing (WLR) and Keel (KLR) between 1 and 4 weeks age were measured. The effect of Genotype and Diet on growth rate was defined by fitting a univariate General Linear Model, while the strength of relationship between traits was examined by use of Pearson's bivariate correlation method. Only BLR was significantly (P<0.05) affected by genotype, while diet significantly (P<0.05) determined WTR, BGR, TLR, WLR, and KLR. Significant (P<0.05) effects of Genotype x Diet interaction on WTR, BLR, BGR, WLR and KLR were observed. The level of correlation between trait rates varied with increasing levels of UUMOSM in both genotypes; exhibiting a direct, inverse, parabola or inverted parabola shaped relationship curve. These results showed that subtle variations in dietary levels of UUMOSM significantly influence the biological growth programme of young broilers, with implications for size and interrelationship of body parts, including shape/conformation. They further showed that substructures within populations such as clusters with non-overlapping nutritional habits (voluntary or forced) influence overall population estimates of inter-trait relationships. The transcriptomic (gene expression) and metabonomic correlates of the phenomenon reported here will be examined in further studies and should yield evidence of underlying mechanisms.
