    (Society of Animal Production, Department of livestock and Avian Science, Wayamba University of Sri Lanka., 2016) Badmos, A.A.; Sola-Ojo, F.E.; Yusuff, A.T.; Oke, S.A.; Amusan, T.O.; Kayode, R.M.O.; Bolarin, O.; Adefalu, L.L.; Lawal, A.O.
    This study was conducted to investigate the comparative nutritional adequacy of cassava leaves, pawpaw leaves and orange peel for snail (Archachatina marginata) feed components. A total of three hundred adult snails (weighing 270 – 300g each) were randomly allocated to five treatments that were replicated five times, and each replicate unit consisted of twenty snails. The diets were formulated to contain 22 % protein and 1 900 Kcal/Kg Metabolizable Energy. The result showed that the control diet (pawpaw leaves based) was most consumed, gave the highest weight gain and visceral weight, but the orange pulp based diet gave most efficient Feed Conversion Ratio (FCR) and dressing percentage (p<0.05). The study recommends the use of the three test ingredients as feed components for the Giant African Land Snails.

    Effect of alligator pepper (Aframommum melegueta) and honey on proximate composition, microbial and sensory properties of West African soft cheese.
    (Nigerian Society for Experimental Biology, 2020) Badmos, A.A.; Odebisi-Omokanye, I.M.; Joseph, J.K.; Yusuff, A.T.; Adeyemi, K.D.; Okoli, F.P.; Arise, A.K.; Salami, Khadijat Onozare; Lawal, A.O.
    Cheese is a highly nutritious food but the supply is highly limited by its short shelf life in the tropics. Several attempts have been made through the use of natural preservatives to increase the shelf life of cheese. In this study, the effect of honey and ether extract of Aframommum melegueta (A. melegueta) on proximate, microbial and sensory properties of cheese was investigated using three levels (0, 3, and 6%) of the two additives in a 3×3 factorial experiment. The sensory value of the cheese samples was assessed by a 30-member panel, the proximate values determined and the bacterial status monitored over a 3-day period. The results showed at 3% level each of honey and ether extract of A. melegueta (3H;3A), there was a significant improvement in the protein and fat content of the soft cheese. The control cheese without the addition of the additives and the cheese fortified with 3% A. melegueta extract were the most acceptable to the sensory panelists. Lactic acid bacteria and non-lactic isolates were isolated from the cheese. The cheese treated with 6 % honey and 6 % A. melegueta extract (6H, 6A) had the lowest bacterial count. The following blends of honey and ether extract of A. melegueta - 6H, 6A; 3H;3A; 0H;6A and 6H;0A is recommended as preservatives and additives of West African Soft Cheese.

    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.

    Investigation on Biochemically Processed Castor Seed Meal in Nutrition and Physiology of Japanese Quails
    (Islamic, Azad University, Rasht Branch, Department of Animal Science, Faculty of Agriculture, Pol-e Taleshan, Rasht, Iran., 2017) Annongu, A.A.; Atteh, J.O.; Joseph, J.K.; Belewu, M.A.; Adeyina, A.O.; Akanbi, A.S.; Yusuff, A.T.; Sola-Ojo, F.E.; Ajide, S.O.; Chimezie, V.O.; Edoh, J.H.
    Native de-oiled and treated castor seed meal was subjected to proximate analysis and quantification of anti-nutrients (phytochemicals). Seed cake was treated by biochemical technique of solid state fermentation with Aspergillus niger and addition of calcium oxide (CaO) to give treated castor seed meal (TCSM). One hundred and twenty Japanese quails (Coturnix coturnix japonica) were fed four (4) iso-nitrogemous and iso-caloric diets containing 0, 2.5, 5.0 and 7.5% TCSM corresponding to the diet 1, 2, 3 and 4, respectively. While the feeding trial lasted for 56 days, feed and water were supplied ad libitum. Data on proximate composition showed that raw seed, defatted residue (cake) and the processed castor seed meal contained valuable nutrients like dry matter, crude protein, fat, fibre, mineral matter and soluble carbohydrate (NFE). Phytochemical quantification gave high levels of the anti-nutrients such as ricin, allergens, ricinine in the raw seed. However, levels of these phytochemicals were reduced by defatting and treatments of the cake meal by solid state fermentation, A. niger and CaO. Performance traits indicated decreases in feed intake, weight gain, growth and increases in mortality rates especially on the diet with the highest (7.5%) inclusion of TCSM compared to the control diet (P<0.05). Nutrients retentions on the test feedstuff were not comparable with values on the reference diet on soluble carbohydrate values which decreased with increasing CSM (P<0.05) relative to the control diet. In haematological parameters packed cell volume (PCV) and mean corpuscular hemoglobin (MCH) values on diets with TCSM were exceptionally high relative to the control diet (P<0.05). However, biochemical indices (serum protein, albumin, globulin, albumin:globulin ratio and alkaline phosphatase (ALP) activities were not influenced by dietary CSM (P>0.05). Enzyme activity of aspartate aminotransferase (AST) showed decreasing trend with increasing level of CSM in diets (P<0.05). Profiling electrolytes in the fed quails showed significant variations in concentrations of Ca++ and HCO3- on TCSM based diets (P<0.05) comparable with the control diet values. Conclusively, despite treating CSM by solid state fermentation with A. niger and CaO addition in this trial, TCSM addition still appears to induce toxic and deleterious effects on the quails. Subsequent works to enable inclusions at acceptable and higher levels after treatments are on-going.

    Repeatability estimates of growth traits in arbor acre broiler chickens fed graded level of probiotics enhanced Moringa oleifera seed meal diets
    (Animal Science Association of Nigeria (ASAN), 2017) Sola-Ojo, F.E.; Fayeye, T.R.; Adedibu, I.I.; Yusuff, A.T.; Badmos, A.A.; Olarinoye, W.O.
    Two hundred (200) Arbor Acre broiler chickens fed four different diets containing 0 (control), 4, 6, and 8% (unconventional) probiotics enhanced Moringa Oleifera seed meal (PEMOSM) were used to estimate repeatability (R) of growth traits during the starter (0-4 weeks) and finisher phases (5-7weeks). The traits considered were body weight, body length, thigh length, drumstick length, shank length, body girth, wing length and keel length. The results showed low to moderate and high R estimates based on the diet fed to chickens and feeding phase (starter and finisher). Moderate to high R (0.47 to 0.99) estimates were obtained for most of the growth traits examined during the starter and finisher phases when the chickens were fed diets containing 0 and 4% PEMOSM, except shank length, thigh length, wing length, body girth and keel length that had low R estimates (0.32 to 0.43) during those period. When the chickens were fed higher levels of PEMOSM, low R estimates (0.30 to 0.47) were obtained for most of the traits except body weight which had 0.62 and 0.52 at 6 and 8% PEMOSM inclusion level during finishers' stage, and keel length with 0.55 at 6% PEMOSM during the starter phase. This findings indicate that nutrition play a major role as an environmental factor that have a significant effect on genetic parameters of chicken and should be taken into consideration when broiler chickens are been considered for genetic improvement.
