    ASSOCIATION BETWEEN PARITY AND CANCER AMONG WOMEN IN NORTH-CENTRAL NIGERIA:AN EXPLORATORY CASE-CONTROL ANALYIS
    (Department of Animal science,Nasarawa State University Keffi, 2014-11-01) Ari, Maikano Mohammed; Ogah, D.M.; Yusuf, N.D.
    Background: Many studies conducted over the years have recognized the substantial epidemiological evidence on the contribution of reproductive factors for the occurrence of breast carcinoma, including parity. However, most studies evaluated relatively homogeneous populations, with a small number of women with high fertility, and the association of very high parity with breast cancer remains poorly understood. Therefore, we addressed this topic in an African population characterized by high fertility rates. Methods: We conducted a case-control analysis among women that were attending the Taimako breast and cervical cancer-screening centre, which is located in Nasarawa state of North-Central Nigeria.results: Among cases, 34.5% of the women were 39 years or less. About a quarter had ever used oral contraceptives, nearly half had attained menopause, and nearly two thirds had parity higher than 4 (parity 5-6, 32.1%; parity 7-8, 25.0%, parity ≥9, 7.1%). Compared to women with parity 1-4 the risk of breast cancer tended to be higher among nulliparous women (OR=3.44, 95%CI: 0.68-17.54), though it was lower among those aged ≤45 years (OR=1.43, 95%CI: 0.11-18.22) and higher in participants aged >45 years (OR=12.07, 95%CI: 0.62-233.00). For women with higher parity, the OR estimates were similar for those with parity 5-6 (OR=2.54, 95%CI: 0.80-8.01) and 7-8 (OR=2.65, 95%CI: 0.74-9.48). conclusion: Our results suggest that future increase in incident breast cancer cases in this setting may result from an improvement of screening and diagnostic services, rather than from a dramatic but unlikely reduction in parity.

    PATH COEFFICIENT MODEL FOR ASSESSMENT OF WEIGHT USING LINEAR TRAITS AT BIRTH AND AT WEANING IN NIGERIAN INDIGENOUS PIG
    (Department of Animal science,Nasarawa State University Keffi, 2014-01-01) Ari, Maikano Mohammed; Ogah, D.M.; Yusuf, N.D.
    Direct and indirect effects of some explanatory variables ((body length (BL), rump height (RH), rump length (RL) , rump width (RW) , shoulder width (SW), wither height (WH), heart girth (HG) and flank length (FL)) influence on live weight at birth and at weaning in Nigerian indigenous pigs, managed under semi intensive system were investigated using path analysis. Results of the analysis indicated that the correlation coefficient between body weight and body length at birth was highest (0.59) while at weaning, rump width had the highest correlation coefficient with body weight (0.60). The relationships were from low to high. The direct effect of linear traits to body weight at birth were highest with wither height and flank length similarly heart girth and rump length had better direct effect on body weight at weaning than other linear traits. The findings show that there is variability in relationship between body weight and linear traits with age, similarly both tissues and bone development play significant role in weight determination in the indigenous pigs. Thus selection for weight increase at adult phase can better be achieved at weaning, providing direction for selection towards increase weight in indigenous pigs.

    Studies on haematology, biochemistry and some physiological parameters of weaned rabbits fed graded level of garlic (Allium sativum L.) as additives
    (Department of Animal Science, Nasarawa State University Keffi, 2021-04-21) Hassan, D.I.; Musa, S.I.; Yusuf, N.D.; Faith, E.A.; Muhammad, Kabir Baba; Mohammed, M.M.; Abimiku, H.K.
    The study examines the effects of garlic (Allium sativum L.) as a supplementary phytogenic feed additive using 246-week old hybrid (Chinchilla x New Zealand White) weaner rabbits of both sexes with initial average weight of 0.52 kg which were divided into five groups of six rabbits each. The groups were randomly assigned to the four treatment diets containing 0g (control), 0.20g, 0.40g, 0.60g and 0.80g powdered garlic respectively. There were significant (P<0.05) differences in most haematological parameters (RBC, Hb, PCV, MCV, MCH and MCHC) measured. A significant (P<0.05) improvement of RBC was observed when 0.20g garlic was supplemented, but however decreased with increasing level. WBC, total protein, globulin, albumin, glucose, cholesterol and urea showed significant (P<0.05) difference with higher increased of total protein at 0.40g in garlic supplementation. The values of pulse rate show a significant (P <0.05) difference with higher increase at 0.40g garlic supplementation while the rectal temperature and respiratory rate where not affected by garlic supplementation (P<0.05). The supplementation of powdered garlic as feed additive could be used for treatment of rabbit’s diseases and used as antibiotics.

    UTILIZATION OF GARLIC (ALLIUM SATIVUM L) AS ASUPPLEMENTARY PHYTOGENIC FEED ADDITIVE FOR BROILERS FED COMMERCIAL FEEDS
    (Department of Animal science,Nasarawa State University Keffi, 2012-01-26) Ari, Maikano Mohammed; Barde, R.E.; Ogah, D.M.; Agade, Y.I.; Yusuf, N.D.; Hassan, I.D.; Muhammed, M.M.
    The study examines the effects of garlic (Allium sativum L) as a supplementary phytogenic feed additive for broilers using one hundred and twenty (120) Lohman broilers that were randomly divided into four (4) experimental groups of two replicates each. Dietary treatments were as follows: T (control), T1, T2 and T3 representing 0, 10, 15 and 20% daily supplementation of garlic per Kilogram of feed at both starter and finisher diets. There were no significant (P>0.05) differences in all performance parameters of experimental birds at both starter and finisher phases except in average body weight gain (BWG) and feed conversion ratio (FCR) at starter phase which showed significant (P<0.05) differences. There were significant (P<0.05) differences in all serum indices measured as Hb %, PCV, Hb g/dl and the garlic supplementation were all negatively correlated (P<0.05) with cholesterol, while PCV, Hb g/dl and garlic supplementation were significantly (P> 0.01) positively correlated with cholesterol, indicating that with increasing in garlic supplementation there was a corresponding increase in other serum metabolites except for cholesterol which was decreased with increase in garlic supplementation. Supplementation with 15% of garlic per kilogram of feed will reduce cholesterol deposition and support performance of broilers.

    VILLAGE CHICKEN FLOCK OWNERSHIP, MANAGEMENT AND CONSTRAINTS IN KEANA, NASARAWA STATE, NIGERIA
    (Department of Animal science,Nasarawa State University Keffi, 2012-11-21) Ari, Maikano Mohammed; Hassan, D.I.; Ogah, D.M.; Yusuf, N.D.; Musa-Azara, Ibrahim Suleiman; Alaga, A.A.
    A survey on Village chicken flock ownership, management and constraints in Keana local government area of Nasarawa State, Nigeria, was carried out using structured questionnaires. One thousand, five hundred (1,500) flock owners were selected using multistage sampling techniques from six villages. Keana town has the highest chicken population (37.02%) followed by Kadarko, Giza, Aloshi, Kwara and Agaza with (24.66, 15.53, 9.06, 8.53 and 5.19% ) respectively. Majority (65.50% )of the flock owners were males while 31.50% are females. A total of 83.87 per cent of the village chicken population is under extensive management system. Breeding was generally uncontrolled. It also showed that the highest population of the village chicken (65.13%) roost on branches of tree at night as compare to 29.20 and 5.67% for those housed at one corner of the main family house and an overhang attached to the roof of the houses respectively. The result of the analysis also showed that major production constraints was diseases (52%) majorly (Newcastle disease, fowl cholera and fowl pox) which is followed by stealing, predators and parasites with 28, 12 and 8% respectively. Local method of treatment ranging from 43.53 to 66.41%, slaughter 4.69 to 28.08% and others sale, gift and no action are methods adopted for controlling diseased flocks. Adequate disease control measures through provision of health facilities and improved housing system are recommended for the communities.
