    EFFECTS OF 4BAC-EXTRA PROBIOTIC SUPPLEMENTATION LEVELS ON PERFORMANCE, EGG QUALITY, NUTRIENT DIGESTIBILITYAND BLOOD PARAMETERS OF SASSO LAYING HENS
    (Department of Animal Science, Nasarawa State University, Keffi, 2018-09-01) Haruna, Hadiza Salihu
    This study was conducted to evaluate the effect of 4Bac-Extra Probiotic supplementation levels on performance, egg quality, nutrient digestibility and biochemical profile of Sasso laying hens using One Hundred and Sixty (160) Sasso layers that were randomly assigned into four treatments with four replicates each representing T1- 0, T2- 5, T3- 10 and T4- 15% supplementation of basal feed with 4Bac-Extra probiotics. During the sixty two days (62 d) experimental period, the birds were managed on deep litter and provided with the experimental feeds and water ad libitum. The parameters measured were body weight, feed intake, body weight gain, feed conversion efficiency, survival percentage, nutrient digestibility, biochemical, hematological parameters and egg quality characteristics. The results obtained indicated no significant (p>0.05) effects on body weight, body weight gain, survival %, and performance index. However, Feed Intake and Feed Conversion Ratio significantly (P<0.05) differ and better in diet T2 (5%) and diet T3 (10%). Nutrient digestibility indicates a significant (P<0.05) difference between treatments with better and higher values in diet T4 for most nutrients measured. Hematological and serum biochemical showed no significant (P>0.05) difference between treatments, similarly the result obtained result obtained from internal and external egg quality indicates no significant (P<0.05) difference. The results obtained from this experiment indicate that the effects of 4-Bac Extra probiotics were only slight. However, inclusion of 5 – 10% was found to have satisfactory effects on birds.

    MULTIVARIATE ANALYSIS OF PHENOTYPIC DIFFERENTIATION IN BUNAJI AND SOKOTO GUDALI CATTLE
    (Department of Animal Science, Nasarawa State University, Keffi., 2010-12-04) Yakubu, Abdulmojeed; Idahor, K.O; Haruna, Hadiza Salihu; Wheto, Mathew; Amusan, Samuel
    The study aimed at examining morphometric differentiation in two Nigerian breeds of cattle using multifactorial discriminant analyses. Ten morphological traits (withers height, rump height,chest circumference, body length, face length, tail length, rump length, head width, rump width and shoulder width) of 224 Bunaji and 87 Sokoto Gudali cattle were measured. The animals, which were aged 2.5−3.6 years, were subjected to extensive management system. The linear type traits of Sokoto Gudali cattle were significantly (P < 0.05) higher than those of their Bunaji counterparts, with the exception of body length and face length respectively. The stepwise discriminant analysis gave a better resolution as only three variables, rump width, withers height and face length were more discriminating in separating the two cattle breeds. The Mahalanobis distance (7.19) between the two cattle populations was high and significant, which is an indication that they belong to genetically different groups. This was complemented by the result of the Nearest Neighbour Discriminant Analysis, where 85.48% of Bunaji cattle were classified into their source population while 96.55% of their Sokoto Gudali counterparts were correctly assigned into their source genetic group. The present phenotypic information will be the basis for the establishment of further characterization, conservation and selection strategies for the two Nigerian breeds of cattle.

    Village guinea fowl (Numidia meleagris) production systems in Nasarawa State, north central Nigeria: flock characteristics, husbandry and productivity
    (Department of Animal Science, Nasarawa State University, Keffi., 2014-04-26) Yakubu, Abdulmojeed; Musa Azara, I.S; Haruna, Hadiza Salihu
    Within the livestock sector, village poultry are often the most commonly owned type of livestock and they are more frequently owned than larger livestock species by resource-poor households. The present study was conducted to investigate the flock characteristics, husbandry and productivity of village guinea fowl (Numidia Meleagris) in Nasarawa State, Nigeria. Data were gathered using a semi-structured questionnaire survey of 117 households cutting across the three agricultural zones of the state. The mean number of guinea fowl owned per household between the study zones was higher in Nasarawa West and Nasarawa Central compared to the Southern Agricultural zone (9.94, 7.36 and 6.29, respectively). The overall cock:hen ratio of the village guinea fowl flocks was 1:2.5, depicting excess breeding males. Majority of the households purchased their foundation stock from the market. While approximately 78% of the respondents provided partial enclosure for their birds, 79% of the households claimed to offer partial feed supplements done in both wet and dry seasons. Women and children were the predominant providers of care for guinea fowls. The mean number of eggs per hen per year was 78.7, of which 56.1 eggs were hatched. Newcastle disease (ND) was the most prevalent disease while ethno veterinary services were used as substitute for conventional veterinary support by 28.2% of the households. About 72% of the village birds were sold at the adult stage and the priority purpose of keeping guinea fowls was mainly for cash (44.4%) and home consumption (26.5%). Losses incurred were due to factors such as poor health care, poor housing, poor feeding and incidence of predation and theft. The effective population size (Ne) and inbreeding rate (ΔF) of 493 and 0.00101 (0.1%) obtained across the three agricultural zones indicated that the guinea fowl populations are not at the risk of extinction. Therefore, better management strategies geared towards increasing the profitability of the village guinea fowl enterprise should be employed.
