    (Department of Agronomy, Nasarawa State University, Keffi., 2020-08-23) Adua, M.M.; Amana, Sani Mathew; Luka, E.G.; Nghargbu, K'Tso
    This study was carried out to quantitatively assess the heavy metal pollution level of soils collected from different landfill and solid waste dumpsite in keffi metropolis of Nasarawa State, Nigeria. Soil samples were collected from different landfill and dumpsites in Keffi metropolis at the depth of 0-30 cm. A total of 5 random samples per location and composited to obtain a laboratory sample. The collected soil sample were allowed to dry under normal temperature within soil sample preparation room of Department of Agronomy Nasarawa State University Shabu Lafia Campus. The analysis for heavy metal was conducted using Atomic Absorption Spectrometer (AAS). The levels of concentration these metals varied across soil among sampling point. The mean order of heavy metal concentration in Keffi is Zn>Fe>Mn>Pb>Al>Cu>Se>Ni>As>Hg respectively. The pollution indices such as Contamination factor (CF), Pollution load index (PLI), Contamination degree (Cd), Potential contamination index (Cp) and potential ecological risk index (RI) were used for the metal enrichment and contamination status was also calculated. The CF, Cd, Cp, PLI and RI values of the studied metals indicated that the study area does not posed risk to local environments. The concentration of heavy metal indicated that the study area does not posed high risk to local community but the odour from the land fill and dumping site pollute the air which causes respiratory problems. Hence, this open landfill should be closed from use in future and or properly managed by recycling in order to minimize future pollution problems. The mean order of heavy metal concentration in plant samples is Fe>Zn>Mn>AL>Pb>Cu>Cr>Ni >As>Hg respectively. The heavy metal (Fe and Zn) contents in the plants were higher compared to other metals analysed. The concentration of some metal was relatively high in the maize plant, but there were all below the WHO permissible limit except for Zn metal. The transfer factor (Tf) revealed that plants grown on dumpsite and landfill soils absorbed and accumulates heavy metals. The highest transfer factor value was obtained in Fe, followed by Cu, Pb, Zn, Al, Mn, Ni and As respectively.

    Effect of Ronoxyme hiphos® supplementation on nutrient digestibility and blood parameters of grower rabbits fed sunflower seed meal-based diets
    (Department of Agricultural Education, Nasarawa State University Keffi, 2020-01-19) Onazi, B.O.; Samuel, Emmanuel Alu; Ogah, D.M.; Adua, M.M.; Muhammad, Kabir Baba
    sunflower seed meal (SFSM) supplemented with enzyme on nutrient digestibility and blood parameters using 72 growing rabbits. Nine diets namely T1 to T9 were compounded to be isocaloric (2500 kcal/kg, ME) and isonitrogenous (15%) with treatments T1, T2 and T3 having 0% inclusion rate of SFS meal and 0PPM, 150PPM and 250PPM of the enzyme supplementation. Treatments T4 to T6 and T7 to T9 had 10 and 20% levels of SFS meal inclusion rate respectively but maintaining same levels of enzyme supplementation as in T1 to T3. This arrangement translated to T1, T4 and T7 serving as the control diets for T2 and T3, T5 and T6 and T8 to T9, respectively. The rabbits were allotted to the three levels of SFS meal (0,10 and 20%) and three levels of enzyme supplementation (0,150, and 250PPM) in a 3x3 factorial arrangement of a completely randomized design (CRD) to produce nine treatment diets. The treatments were replicated four times. Crude fibre, neutral detergent fibre, acid detergent fibre and cellulose were significantly (P<0.05) higher in rabbit fed 20% (84.58%, 72.24%, 67.16% and 64.27%) SFS diet than 0% (64.20%, 66.68%, 59.40% and 57.81%) and 10% (76.88%, 70.63%, 64.04% and 61.90%) respectively. Enzyme supplementation significantly (P<0.05) improved RBC, the values increased from 5.23 x1012/l for non-enzyme supplementation to 5.38 -5.73 x1012/l. Red blood cell and was significantly (P<0.05) lower in rabbits fed T4 diet than the other groups. Similarly, haemoglobin (11.42 vs. 11.37 and 12.01 g/dl), cholesterol (3.83 vs. 4.33 and 4.31mmol/l) and triglyceride (0.95 vs. 1.16 and 1.03mmol/l) were improved (P<0.05) as the level of enzyme supplementation increased in the diets. In view of the significant improvement in nutrient digestibility and some of the blood parameters recorded, rabbit farmers can use the 150 PPM of the enzyme in SFS meal based diets without affecting the nutrient digestibility and health of the rabbits

    Heamatological Parameters of Tick Infested Bunaji Cattle Breeds in Lafia, North Central Nigeria
    (Department of Animal Science, Nasarawa State Univerisity Keffi, 2020-06-13) Adua, M.M.; Muhammad, Kabir Baba; Ibrahim, A.O.
    A study on haematological parameters of tick infested bunaji cattle was carried out between the months of June to July in Lafia, North Central Nigeria to determine the level of tick infestation contributed by various tick species as well as their effects on haematological parameters of the animals using standard parasitological and haematological procedures. A total number of 110 bunaji cattle were sampled from three different locations. Eighty five (73.27%) of the animals were infested with various species of ticks (Ablyomma variegatum, Rhipicephalus appendiculatus, Boophilus decoloratus and Hyalomma truncatus). the result based on the type of cattle revealed that cows had the highest infestation (26.36%) but however, bulls, heifers, and bull calves had 24.55%, 2.00 and 6.36% respectively. Ablyomma variegatum accounted for a significantly (P<0.05) higher infestation rate 38.18 .whereas, 16.36, 11.82, 4.55% and 6.36 was seen on animals infested with Rhipicephalus appendiculatus, Boophilus decoloratus, Hyalomma truncatus and mixed infestations respectively. A significant difference (P<0.05) was observed between infested and non-infested animals on Packed cell volume (PCV), Monocyte and Eosinophil. In contrast, Haemoglobin, Neutrophil, Lymphocyte and Basophil were not significantly affected (P>0.05). Ablyomma variegatum, Rhipicephalus appendiculatus, Hyalomma truncatus and Boophilus decoloratus are the most economical important tick species affecting Bunaji cattle. Moreover, haematological parameters of bunaji cattle are greatly affected by tick infestation. Routine evaluation of infestation level and management practice should be carried out by livestock farmers on their farm to reduce the level of ticks as well as their breeding places

    Heavy metal Contamination and Ecological Risk Assessment of soil around open landfill and dump site in Lafia metropolis and its potential impact on environment and urban community.
    (Department of Agronomy, Nasarawa State University, Keffi., 2020-04-18) Adua, M.M.; Amana, Sani Mathew; Luka, E.G.; Nghargbu, K'Tso
    The study was aimed at determining the status of heavy metal Contamination and Ecological Risk Assessment of soil around open landfill and dump site in Lafia metropolis and its potential impact on environment and urban community. Soil samples were collected from different landfill and dumpsites in Lafia metropolis at the depth of 0 – 30 cm. The analysis for heavy metal was conducted using Atomic Absorption Spectrometer (AAS). The result of heavy metals across sampling sites in Lafia indicated the mean order of heavy metal concentration as Zn>Fe>Al>Mn>Pb>Cu>Ni>Se>As>Hg respectively. The levels of concentration of these metals varied across soil sampling points. The pollution indices such as Contamination factor (CF), Pollution load index (PLI), Contamination degree (Cd), Potential contamination index (Cp), potential ecological risk index (RI) were used for the metal enrichment and contamination status. The CF, Cd, Cp, PLI and RI value of the present work indicating that the soils of these sites are not polluted by heavy metals. The mean order of heavy metal concentration in plant samples are Fe>Zn>Mn >AL> Pb >Cu>Cr>Ni >As>Hg respectively. The result showed a wide range of values in the various elements measured. The heavy metal (Fe and Zn) contents in the plants were higher compared to other metals in all the sites. The concentration of some metal was relatively high in the maize plant, but they were all below the WHO permissible limit except for Zn metal. The transfer factor (Tf) revealed that plants grown on dumpsite and landfill soils absorbed and accumulates heavy metals. The highest transfer factor value was obtained in Fe, followed by Cu, Pb, Zn, Al, Mn, Ni and As respectively. The correlation analysis indicates significant negative correlation in soil and significantly and positively in plant of metals. The concentration of heavy metal indicated that the study area does not posed high risk to local community but the odour from the land fill and dumping site pollute the air which causes respiratory problems. Hence, this open landfill should be closed or properly managed by recycling in order to minimize future pollution problems.

    Preliminary investigation on communitybased intervention through cockerel exchange programme for sustainable improved rural chicken production in Nasarawa State, Nigeria
    (Department of Animal science,Nasarawa State University Keffi, 2014-01-01) Ari, Maikano Mohammed; Yakubu, A.; Ogbe, A.O.; Ogah, D.M.; Adua, M.M.; Idahor, K.O.; Samuel, Emmanuel Alu; Ishaq, A.S.; Salau, E.S.
    Local chickens play an important role for smallholders and contribute significantly to food security of households in rural and semi-urban communities. However, the poultry sector is beset with low productivity in Nigeria. The present study aimed at improving the performance of rural chickens in Nasarawa State through cockerel exchange programme. A total of one hundred and eighty (180), 25-week old cockerels were obtained from a reputable farm in the State. Forty eight (48) households from Danka Sarki Extension Village (University’s Extension Model Village) and ten (10) households from COAL Staff quarters were randomly selected. Each participating farmer (household) was given cockerels depending on the number given in return for his/her own cock(s). Pre- and Post-trial information was obtained on flock size, number of chicks, growers, cocks and hens including number of clutch/bird, eggs/clutch, eggs hatched per clutch, mortality and body weights of chicks and growers. There was no significant difference in the flock size of birds before intervention and after intervention. The mortality rate of chicks/clutch and growers/clutch within the first nine months of study decreased as a result of the introduction of cockerels. Similarly, body weights of chick sand growers of post-intervention birds were higher. The distribution of cockerels (improved exotic birds) to the rural livestock farmers in the study areas appeared to contribute to improved village chicken production.
