    Performance of starter broilers fed anaerobically fermented and lyle treated Delonix regia seed meal
    (Pakistan Journal of Nutrition, Asian Network for Scientific Information, 2008) Egena, S.S.A.; Usman, Abdulkadir; Shiawoya, E.L.; Yahaya, S.K.; Ogunlowo, H.O.
    One hundred and twenty day-old Hubbard broiler birds were used to study the effects of anaerobic fermentation and lyle treatment of Delonix seed meal on the performance of starter broilers. The experimental period spanned 5 weeks. The birds were divided into four treatment groups of three replicates each using complete randomized design. The anaerobically fermented and lyle treated Delonix seed meal (AFLTDSM) was used to replace groundnut cake (GNC) at 0%, 5% and 7.5% level. Untreated raw Delonix seed meal (URDSM) was also used at 5% level in order to evaluate its effects on starter broiler performance. The four treatments were designated as T1, T2, T3 and T4 respectively. Parameters evaluated were mean body weight, daily body weight gain, mean feed intake, mean feed conversion ratio as well as apparent nutrient digestibility. The results showed that mean body weight, daily body weight gain, mean feed intake and mean feed conversion ratio were not significantly affected (p>0.05) by the substitution of GNC with AFLTDSM in the diets. However, apparent nutrient digestibility of dry matter (DM), crude protein (CP), ash, ether extract (EE) and Nitrogen free extract (NFE) were significantly affected (p<0.05) by the treatment diets. Crude fibre (CF) digestibility was however not affected (p>0.05) by the inclusion of Delonix seed meal in the diets. It was concluded that AFLTDSM could be used as a substitute for GNC in starter broilers diet without any significant effect on the performance of the birds.

    Haematological Values of Broilers Managed on Titanium Dioxide Treated Litter
    (International Invention Journal of Medicine and Medical Sciences, 2015-10) Adamy, Y. A.; Usman, Abdulkadir; Mera, U. M.; Abubakar, M. B.; Bello, A.; Umaru, M. A.
    An experiment was conducted to study the effect of TiO2 applied in Og/m", 30g/m, 60g/m and 120g/m concentration, as a litter treatment agent on litter bacteriology, haematology, ammonla emisslon and ammonia lesions on broilers fed standard commercial diet and water ad lib on wood shavings based deep litter system at a depth of 6cm and 16birds/m. Litter samples were collected weekly for ammonia while tissue samples were collected at the seventh week for histology and blood samples were als0 collected via cardiac venipuncture for haematology and blood chemistry. The result showed that RBC and wc were significantly (P<0.05) elevated in Og/mTio, treatment (3.86x10, 2.93x10, 3.01x102 2.34x10 and 27.16x10", 26.41x10', 21.47x10", 21.84x10") respectively. MCH and MCV were significantly (P<0.05) elevated (28.60pg, 34.26pg, 30.96pg, 44.71pg and 87.42f, 103.41fl, 93.62f1, 134.52f1) in the 120g/m Tiolitter treatments. There was a significant (P<0.05) elevation in serum sodium (132.27mEq/, 135.07mEql, 135.33mEql, 138.67mEq/); potassium (4.12mEq/, 4.18mEq/l, 4.03mEq/, 4.47mEq/); globulin (1.23g/dl, 1.85g/dl. 1.35g/dl, 2.47g/dl) and conjugated bilirubin (5.11mgldl, 5.52mg/dl, 5.56mgidi, 6.07mg/di) in 120g/mTio, litter treatment. There was no significant difference (P>0.05) in ammonia even though 60g/m°Tio, litter treatment retained more ammonia (29.77, 29.25, 33.16, 30.01). It was concluded that Tio, is beneficial as a litter treatment agent especially at 60g/m rate.

    Mathematical Modeling of an Intelligent Poultry Feed Dispensing System
    (Journal of Digital Innovations & Contemp Res. In Sc., Eng & Tech, Creative Research Publishers for the International Center for IT and Developments, 2017-06-13) Ameh, C.A.,; Olaniyi, O.M; Dogo, E.M.,; Usman, Abdulkadir; Aliyu, S.,; Alkali, B
    Abstract Abstract The mathematical modeling of control systems and other industrial applications has helped to shape the design and performance of different systems. One of the problems faced by existing designs of poultry feed dispensing system in the tropics is feed wastage often resulting in high cost of production. Several measures that can be used to evaluate the performance of poultry flock especially broilers are growth rate, days to market, mortality, and feed efficiency. Feed is typically the most costly expense in broiler production. As a result, feed efficiency is typically the primary tool by which a flock is evaluated. This research mathematically model an intelligent poultry feed dispensing system that will dispense both solid and liquid feed which will reduce the unusual level of human involvement, feed wastage, contamination and high cost of production. The mathematical model encompasses the speed control of a DC motor which will regulate the to and fro motion of the conveyor brushes and control the flow of the solid feed. The control of the digital valves regulates the flow rate of the liquid feed in and out of the dispensing system. The mathematical model was simulated in MATLAB r2015b environment. The simulated results showed that the system under state-space is controllable and observable when the Kalman matrix test was carried out. At the end, a dynamic model for optimized balance among better yield, returns on investment and cost of operation in dispensing poultry feed was developed.

    Blood biochemistry and haematology of weaner rabbits fed sundried, ensiled, and fermented cassava peel based diets
    (Pakistan Journal of Nutrition, Asian Network for Scientific Information, 2006) Ahamefule, F. O; Eduok, G. O.; Usman, A; Amaefule, K. U.; Obua, B. E.; Oguike, S. A.
    Twenty-four New Zealand white × Chinchilla weaner bucks, aged between 7 and 8 weeks and averaging 0.9 kg in weight, were divided into four groups of six each and used in a 12-week feeding trial to evaluate the blood biochemistry and haematology of rabbits fed sun-dried, ensiled, and fermented cassava peel-based diets. The test diets designated A, B, C and D were completely randomised. Diet A, the control, was a 16.18 per cent CP (crude protein) weaner ration formulated from maize, maize offals, soya bean meal, blood meal, oyster shell, bone meal, vitamin premix, and common salt. Diets B, C and D were also weaner rations of, respectively, 16.10, 16.20 and 16.08 per cent CP in which 10 per cent maize of the control diet was replaced, respectively, with sun-dried, ensiled and fermented cassava peels. The diets were roughly iso-caloric. The haematological components of the study included packed cell volume (PCV), white blood cells (WBC), neutrophil (N), and lymphocytes (L). The biochemical parameters were serum creatinine, urea, bilirubin (total and conjugated), serum glutamic transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT), eosinophil, and blood sugar. Liver and kidney weights were also monitored. The results showed that PCV, WBC, N and L were affected (P<0.05) by experimental diets. Also affected (P<0.05) were bilirubin, SGPT and SGOT. However, serum creatinine, urea and eosinophil were unaffected (P>0.05) by treatment diets. Liver and kidney weights also did not differ (P>0.05) among rabbits fed different dietary treatments.

    Some biological activities of Garcinia kola in growing rats
    (VETERINARSKI ARHIV , Printed in Croatia, 2001-10-23) Uko, Otor John; Usman, Abdulkadir; Ataja, Mohammed Abu
    The biological activities of water extract from Garcinia kola (G. kola) were investigated in growing Wistar rats. Three doses of G. kola extract (0, 10, 20 mg G. kola/100g body mass of rat) were administered daily by gavage to the respective groups of 15 rats for a period of 70 days. The animals were offered standard rat diet and water ad libitum. The plant extract had a depressive effect (P<0.01) on appetite and water intake with resultant poor (P<0.05) feed utilization efficiency and mass gain of rats in a dose-dependent manner. Plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities were elevated (P<0.05) but histological examinations of liver, heart and lungs of experimental rats revealed no alterations. Nevertheless, a significant (P<0.05) increase in leucocyte counts was adduced for possible mild degenerative changes in these organs. The extract enhanced sexual interest (libido) of the male rats but did not necessarily improve their fertility rate.

    Effect of sex, wattle, beard, hair type, and extra teat on growth-related traits of extensively managed goat (Capra aegagrus) population of Niger State, Nigeria.
    (Equity Journal of Science and Technology, 2016) Kolo, P. S.; Egena, S. S. A.; Tsado, D. N.; Adisa-Shehu, M
    Astudy that evaluated the effect of sex, wattle, beard, hair type and extra teat on growth traits of goats extensively managed in the three Senatorial zones ( i.e zones A, B and C) of Niger state was carried out. The growth traits evaluated include body weight, body length, height-at-withers, chest depth, chest girth, head length, head width, rump length, rump width, shin circumference, fore leg length and hind leg length.Male goats had better (p<0.05) measurement in all parameters considered in zone B of the state while the females were better (p<0.05) in all parameters measured in zones A and C except for shin circumference in which the males were better in zone A. Goats without wattle showed superiority (p<0.05) in most of the parameters measured in zone C. This was not so for goats in zones A and B as there was no clear demarcation between goats with or without wattle. Goats with beard were superior (p<0.05) in most of the parameters measured in zones B and C. Coarse hair type had significant (p<0.05) effect on body weight and all the other body measurements except for height-at-withers which was not significantly (p>0.05)affected. Soft hair had significant (p<0.05) effect on body weight, and all the body measurements except for hind leg length which showed no significant (p>0.05) difference. Extra teat had no significant (p>0.05) effect on body weight, body length height-at-withers, chest depth, chest girth, head length, rump width, shin circumference and hind leg length but significantly (p<0.05) influenced head width, rump length and fore leg length. Absence of extra teat had significant (p<0.05) effect on all the parameters measured except for head length which showed no significant (p>0.05) difference. At the end of the study, it was observed that sex and major genes had significant effect on most of the parameters measured. It is recommended based on the result emanating from the study that farmers be encouraged to rear goats with beard, those without extra teat and wattle since they were better in most of the parameters measured.

    Performance and haematological profile of broiler starter birds fed graded levels of raw Allamanda cathartica (L) seed Meal diet.
    (Journal of Agriculture, 2012) Malik, A. A.; , Aremu. A; . Adelowo, A.; Kolo, P. S.; Haruna, B. G.
    The response of 120 day-old broiler starter birds to graded dietary inclusion levels of 0.0 %, 2.5 %, 5.0 %, 7.5 % and 10.0 % of raw Allamanda cathartica (L) seed meal (ACSM) to form diets 1, 2, 3, 4 and 5 respectively was investigated. The isocaloric and isonitrogenous diets were fed to the birds for 4 weeks, after which a digestibility trial was carried out. Blood samples were collected for haematological and biochemical analyses at the end of the second week. Feed intake/bird/week and weight gain/bird/week decreased progressively as the dietary inclusion level of ACSM increased (280.52g/209.34g, 160.20g/99.50g, 90.41g/53.18g, 70.10g/38.73g and 41.30g/21.51g for diets 1, 2, 3, 4 and 5 respectively); while feed conversion ratio increased progressively (p<0.05) as the dietaryACSM level increased (1.34, 1.61, 1.70, 1.81 and 1.92 for diets 1, 2, 3, 4 and 5 respectively). No mortality was recorded for the control diet (with 0 % dietary inclusion level of ACSM), while mortality increased progressively asthe dietary ACSM level increased (p<0.05), reaching up to 100 % at 10 % inclusion level. Dietary treatments had no effect on ether extract digestibility but birds on 0 % and 5 % ACSM diet significantly digested crude protein and crude fibre better than the 2.5 % ACSM diet. No significant (p>0.05) effect was observed on all the haematological and biochemical parameters investigated for the five dietary treatments. It is therefore concluded that ACSM contains potent anti-nutritional factors which are extremely toxic to broiler starter birds at whatever dietary inclusion level. So, there is the greatest need to detoxify the raw seed meal before it can be effectively incorporated into broiler starter diets.

    Phenotypic and genetic categorization of qualitative traits in extensively managed local goat (Capra aegagrus) population of Niger State, Nigeria
    (Nigerian Journal of Genetics, 2015-10-09) Kolo, P. S.; Egena, S.S.A.; Tsado, D.N.; Adisa-Shehu, M.
    A study on the distribution and frequencies of coat colour, wattle, beard, horn, and hair type using 375 extensively managed local goats wascarried out in the three administrative zones of Niger state, Nigeria. The animals were scored for coat colour pigmentation pattern, presence orabsence of wattle, beard, horn, hair type and extra teat. The study showed that light brown is the predominant colour in zones A (43.24%) and zone C (47.57%). Dark brown colour was predominant in zone B (37.82%) followed by light brown (31.09%). The observed frequencies for wattle (Waw) and extra teat (Ete) were above (p < 0.01) the expected Mendelian value of 75% for a dominant gene in all the zones (90.34, 86.55, 87.39 percent for wattle and 91.73, 96.64, 98.21, percent for extra teat in zones A, B, and C, respectively). The gene frequency for beard (Brb) were significantly lower (p < 0.01) than the expected Mendelian value of 75% for a dominant gene in zone A (66.20%) and zone B (55.46%), butwas higher in zone C (83.78%). The gene frequency for polledness (Pop) was 0.00% for all the zones. The gene frequency for soft hair.was more than (p < 0.01) the expected Mendelian value of 75% for dominant genes in zone C (87.33%) but fell short in zone A (60.69%) and zone B (43.70%), respectively. It was concluded that coat colour variation exist in local goats reared extensively in Niger state.
