    A Binary Logit Estimation of Factors Influencing Awareness about Grasscutter Farming among Rural and Sub-urban Households in Kwara State, Nigeria
    (World Journal of Agricultural Research, 2017) Salau, S. A.; Yusuf, O. J.; Apata, D. F.; Adesina, O. M.
    Hunting of grass cutter for food in Nigeria is unsustainable due to serious challenges posed to the ecosystems, adequate bush meat supply and human health. To enhance sustainable exploitation, grass cutter farming is desirable but large percentage of the population still lack awareness about grass cutter rearing. This study was aimed at investigating factors influencing awareness about grass cutter farming in Kwara state. A two–stage sampling technique was used to select 540 participants from rural and sub-urban households for the study. Descriptive statistics and binary logistic regression model were used to analyze the data. The results showed that the respondents had an average age of 46 years with an average family size of 7 persons. Majority (77%) of the respondents were males. The Nagelkerke R2, explained 80.9% of the total variation in awareness of households. The coefficient of age, gender, household size, education, and access to credit with the t-values of -2.333, 1.959, 2.000, 2.235 and 13.832 respectively were all found to be critical in explaining awareness among the sampled households. Based on the findings of this study, it was recommended that any intervention strategy on grass cutter farming by government and international development agencies should have a capacity-building component center on educating households about the management practices and livelihood merits of farm grass cutters. Increase awareness through media should be promoted and policies like loan schemes that would substantially improve households’ access to use and acquisition of credits should be encouraged

    Growth performance and survival of two broiler strains treated with Morinda lucida leaf extract at finisher phase.
    (Ladoke Akintola University of Technology, Nigeria., 2020) Adesina, O. M.
    Antibiotic growth promoters (AGP) use in livestock production is indicted in residual antibiotics and antimicrobial resistance in animal and human populations necessitating search for safer alternatives. Morinda lucida (Brimstone tree), a Phytobiotic with antimicrobial activities, less toxicity and residue free product is a potential alternative growth promoter in broilers. Information is however scanty on its use in tropical broiler production as growth promoter. This study investigated growth performance and survival of broilers over 42-day period when drinking water is supplemented with Morinda lucida leaf extract (MLE). A total of 150 broiler day old chicks comprising of 75 each of Arbor acre and Ross were brooded for 3 weeks and randomly allocated to 5 treatment groups consisting of 3 replicates of 5 birds per replicate. A 2 x 5 factorial arrangement in completely randomized experimental design was used to test the effect of two strains of broiler and five dosage levels of MLE. The MLE experimental groups include 0g/l MLE (control); 1g/l Oxytetracycline; 0.5g/l MLE; 1g/l MLE and 1.5g/l MLE. Data on survival and growth were analysed using Kaplan-Meier log rank test and two-way analysis of variance (ANOVA) respectively. The final body weight, daily weight gains and feed conversion ratio (FCR) of broilers were significantly (p < 0.05) increased by 30%, 34% and 25% respectively relative to the control when MLE was applied at 1.5g/l of water. MLE administered as 1.5g/l through drinking water is therefore recommended as alternative growth promoter to AGP in broiler production

    OPTIMISATION OF N-ETHYL-N-NITROSOUREA (ENU) DOSE FOR MUTAGENESIS IN THE NIGERIAN YORUBA ECOTYPE CHICKEN
    (Proceedings of 42nd annual Conference of Nigerian Society for Animal Production: In Emerging Challenges facing Animal Agriculture in Nigeria and the way forward. (Eds. A. A. Adeloye, E. O. oyawoye, A. A. Toye, B. T. Adesina)., 2017) Adesina, O. M.; Ikeobi, C. O. N.; Oduntan, R. O.; Hanotte, O.; Toye, A. A.
    The otimal dose and regime of ENU for mutagenesis in the chicken was determined through dose titration (0mg/kg body weight, control group; 100mg; 200mg; 300mg and 400mg/kg body weight) and regime variation (single shot, half dose in each of two cosecutive weeks, and 1/3 dose in each of 3 consecutive weeks) studies in one hundred and twenty (120) 25 week-old improved Nigerian local chicken cocks. The study was laid out as a 5 x 3 factorial layout of treatments within a completely randomised experimetal design. Eight individually tagged cocks were assigned to each treatment. Mortality was recorded over 48 hours from the point of each ENU administration. From week 5 – 14 following completion of the assigned ENU dose/regime, semen was collected from each ENU mutagenized cock twice weekly and used to inseminate two Issa brown commercial layers hen i.e. 1 : 2 mating ratio and a total of 240 hens used. Eggs were collected over a period of 5 days in each week and set in an egg incubator to test fertility (candling at day 12). The data showed that ENU dose and regime independently and significantly (p < 0.05) control fertility. The 400mg dose produced significantly lower fertility than the control group throughout the examined period, indicating an absence of recovery of fertility to levels comparable to the Control group. There was transient loss of fertility in the 300mg dose group relative to the control group in weeks 6, 8, 10, 11 and 13 and at week 14, fertility was not significantly (p > 0.05) different from the control group. The 200mg dose showed no significant loss of fertility throughout the experimental period, and this was mirrored in the 100mg group except at week 10. ENU regime significantly (p < 0.05) detrmined fertility at weeks 7 and 9 – 11 only. Administration of 1/3 dose in each of 3 consecutive weeks resulted in the longest period of consistent loss of fertility (weeks 9 – 11) relative to the group given the assigned dose in a single shot regime. Cummulative mortality within 48 hours after ENU administration was significantly determined by dose (0mg, 100mg, 200mg < 300mg < 400mg) and regime (1 dose > 2 doses, 3 doses). The 300 mg dose administered in 3 equal fractions over 3 weeks resulted in transient sterility and recovery and is therefore recommended for ENU mutagenesis in Nigerian Local chicken.
