    Effects of Moringa Oleifera Linn Seed Administration on Sperm Production Rate and Gonadal Sperm Reserve in Rabbits
    (Department of Animal science,Nasarawa State University Keffi, 2014-03-15) Ari, Maikano Mohammed; Musa-Azara, Ibrahim Suleiman; Jibrin, M.; Hassan, D.I.; Ogah, D.M.
    Aim of Study: To investigate the effects of oral administration of moringa seed on sperm production rate and gonadal sperm reserve in rabbits. Study Design: 7 Month old mixed breed male rabbits were randomly assigned into two treatment groups. Group 1(n=30) was the control group whereas the rabbits in group 2 (n=30) were administered Moringa oleifera seed powder in drinking water (250mg/L). After 4 weeks, the gonadal sperm reserve, daily sperm production, sperm production per gram testes and testicular dimensions (weight, volume and density) was compared between the two groups. Place and Duration of Study: Livestock farm, College of Agriculture, Lafia, Nasarawa state, Nigeria, from May to June 2013. Methodology: Gonadal sperm reserve was estimated using a haemocytometer. Testicular weight and volume were determined using laboratory scale and water displacement method respectively. Parenchyma (1g) of each testis was sectioned and homogenized in 10ml of normal saline. The homogenate was filtered through 2 layers of loosely netted bandage. Spermatozoa number was determined using an improved Neubauer chamber. Daily sperm production (DSP) was estimated by dividing the gonadal sperm reserve by a time divisor of 3.66 corresponding to the time in days of the duration of the seminiferous epithelium cycle. Daily sperm production per gram testes (DSPG) was determined by dividing the DSP by the weight of testicular parenchyma.Results: The results indicate significantly higher gonadal sperm reserve and daily sperm production for the control group compared to the treatment,(4.37±.18 to 3.27±.32 and 1.20±.06 to 0.77±.09) Mean values of daily sperm production per gram testes were however similar for all groups(0.53±.03 and 0.47±.20). Testicular weight (2.20±.06 to 1.43±.12) and volume (2.20±.15 to 1.73±.07) were significantly higher for the control group compared to treatment (P=0.05). Tissue density was similar for both groups (1.01±.05 to 0.82±.07).

    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.

    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.
