    The study aimed at describing objectively the interdependence between body weight (BWT) and morphometric traits in Khaki Campbell and Pekin ducks using multivariate path analysis technique. Measurements were taken on one hundred and ninety seven (197) randomly selected 10-week old Khaki Campbell and Pekin ducks, respectively in Plateau State, Nigeria. The birds were reared on deep litter in a semi-intensive system where they were kept in a fenced area provided with water ponds and locked up in the poultry house during the night. The body parts measured were, body length (BDL); thigh length (THL); thigh circumference (THC); breast circumference (BTC); bill length (BLL); neck length (NKL); neck circumference (NKC); shank length (SHL); shank width (SHW); total leg length (TLL) and wing length (WL). General linear model was used to study genotype and sex effects. Pekin ducks had a superior advantage (p<0.05) over their Khaki Campbell counterparts in all the body parameters estimated. Sexual dimorphism (p<0.05) was in favour of male ducks. Pairwise phenotype correlations between BWT and morphometric traits were positive and significant (p<0.01), ranging from 0.38-0.95 and 0.35-0.92 for Khaki Campbell and Pekin ducks, respectively. Path analysis revealed that BDL was the variable of utmost importance directly influencing BWT in male Khaki Campbell and Pekin ducks (path coefficient=0.535 and 0.508, respectively; p<0.01) while BTC and SHL were the most responsible parameters affecting BWT in female Khaki Campbell and Pekin ducks [path coefficient=0.594 (P<0.01) and 1.197 (p<0.05), respectively]. The optimum regression models for the prediction of BWT in Khaki Campbell ducks included BDL, SHL, BTC and NKC (male) and BDL, WNL and BTC (female); while in their Pekin counterparts, BDL, BLL and BTC (male) and BDL and SHL (female) were incorporated.

    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).

    Effects of Utilization of Crushed, Boiled and Fermented Roselle Seeds (Hibiscus sabdariffa) on the Performance of Broiler Chickens
    (Department of Animal science,Nasarawa State University Keffi, 2013-07-01) Ari, Maikano Mohammed; Ogah, Danlami Moses; Idris, Danladi Hassan; Musa-Azara, Ibrahim Suleiman; Nuhu, Dalami Hassan; Samuel, Emmanuel Alu
    of Study: The study examines the effects of utilization of crushed (CRRS), boiled(HTRS) and fermented (FRS) Roselle seeds (Hibiscus sabdariffa) on the performance of broiler chickens Study Design: A total of 135 Anak day-old broiler chicks were randomly assigned to three (3) experimental groups of three (3) replicates using completely randomized design, data collected were subjected to ANOVA using SPSS and Likert scaling technique. Place and Duration of Study: Livestock Complex, College of Agriculture, Lafia, Nasarawa state, Nigeria: February 2012 to April 2012.Methodology: The effects of inclusion of differently processed Roselle seeds on performance traits of experimental birds were evaluated through feeding trials (1- 28 d) and (29- 50 d) at starter and finisher phases. Dietary treatments were as follows: D1, D2 and D3 representing Crushing of Raw Rosselle Seeds (CRRS); Hydrothermally Processed Rosselle Seeds (HTRS) and Fermented Rosselle Seeds (FRS) base diets.Results: No significant (P=0.05) difference in the following parameters: initial weight, feed intake, FCR and survival percentage in the starter phase while the finisher phase significantly (P=0.05) differ only the performance index. Overall scoring of performance parameters showed those birds in D3 group were better than D2 and D1 in that order Conclusion: Roselle seeds inclusion in broiler diets provides effective mechanism for the improvement in performance traits of broilers and fermentation of rosselle (Hibiscus sabdarif) is best processing method.

    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.
