    (Departments of Aquaculture and Fisheries Management, Nasarawa State University, Keffi, 2017-01) Lawee, A.Y.; Danwali, M.I.; Kigbu, A.A.; Samuel, Emmanuel Alu
    The study evaluated the effect of including graded levels of melon shell in diets of Heterobranchus bidorsalis juveniles (13.30±1.20). This study was conducted for 8 weeks. The diet constitute 42% crude protein content with melon shell at different inclusion levels of 0%, 25%, 50%, 75% and 100% respectively. Fish in each tank was fed 3% body weight of diet twice daily. Weights of fish were taken weekly. Data collected were analyzed using One way Analysis of Variance (ANOVA). The result showed that the ash content ranged from 2.80 in fish fed diet one to 4.03 in fish fed diet four. Crude fibre content ranged from 8.52 of fish fed diet one to 12.99 in fish fed diet five. Also, Ether extract ranged from 7.90 in fish fed diet one to 17.45 in fish fed diet five while the crude protein content values ranged from 39.66 in fish fed diet one to 40.05 in fish fed in diet five. The proximate values of the experimental diets showed a significant differences (P<0.05) among treatments.

    NUTRITIONAL QUALITY OF SHEA BUTTER SEED (VITELLARIA PARADOXA) MEAL COOKED AT DIFFERENT DURATIONS
    (Department of Animal Science, Nasarawa State Univerisity Keffi, 2018-09-11) Samuel, Emmanuel Alu; Randa, E.A.; Lawee, A.Y.; Muhammad, Kabir Baba
    A test-tube experiment was carried out to investigate the effect of cooking duration on nutrients and anti-nutrient composition of shea butter seed meal (SBSM). Five grams of unprocessed SBSM sample labeled T1 (UP) was milled to a size of 0.5 mm. Another portion of about 500g of the wet unprocessed SBM was cooked at boiling point and samples were taken at 30, 60, 90 and 120 minutes and labeled T2, T3, T4 and T5, respectively. At the end of the processing, each treatment was replicated twice and samples were taken for analysis. There was no significant variation (P>0.05) in the proximate composition as well as the metabolizable energy value. However, cooking of SBSM for 60 minutes gave better crude protein value of 15.48% while 30 minutes cooking produced the lowest (2530.00 kcal/kg) metabolizable energy. There was significant variation (P<0.05) on the magnesium composition of shea butter cooked at varying times. Anti-nutritional factors namely tannin (0.00%), saponin (0.13 – 0.18%), phytate (0.01%), oxalate (0.01%), flavonoids (0.01%) and trypsin inhibitor activity (3.98 – 5.50 mg/g), of SBSM showed that there was no significant variation (P>0.05) due to the treatment. The fat and water soluble vitamins and amino acid composition were also not affected (P<0.05) by the treatment. Monogastric animal farmers can therefore, cook shear butter seed meal for at least 60 minutes and conveniently feed their animals as a replacement for conventional energy source without affecting the well-being of the animals.

    SHORT-TERM EFFECTS OF BASAGRAN HERBICIDE ON BEHAVIOR AND SOME HAEMATOLOGICAL CHARACTERISTICS OF C. gariepinus.
    (Department of Aquaculture and Fisheries Management, Nasarawa State University, Keffi, 2017-01-11) Lawee, A.Y.; Kigbu, A.A.; Danwali, M.I.
    The influences of basagran, a widely used herbicide on the behavioural actions,( Opercular and tail fin beats) per minutes and the haematological characteristics of blood on juveniles of C. gariepinus were investigated under laboratory conditions. The orders of behavior of the fish were restlessness, loss of balance, air gulping and period of quiescence and finally death. Also, blood and mucus around the gills of the fish certified death were observed. However, the intensity of their actions and mucus accumulation were more pronounced in tanks containing the higher levels of the toxicant. The opercula ventilation and tail fin beats ware significantly (P<0.05) higher than in the control fish at the exposure period of 12, 24 and 48hrs. By 72- 96-hrs both the opercula and tail fin beats of the exposed fish showed marked reduction compared to the control tanks. The results of the opercula and tail fin beats were seen to be dose-dependent. Haematological results showed a significant (P<0.05) reduction in the values of haematocrit and total erythrocytes count with increase in concentration and time of exposure where as the values of total leucocytes count increase with increase in concentration.
