    EFFECT OF DIETARY LEVELS OF TOASTED WATERMELON (CITRULLUS LANATUS, THUMB) SEED MEAL FOR SOYABEAN ON CARCASS AND INTERNAL ORGAN CHARACTERISTICS OF BROILER CHICKENS
    (Department Of Science And Laboratory Technology, Nasarawa State University Keffi., 2016-04-09) Lakurbe, O. A.; Doma, U. D.
    A seven-week feeding trial was conducted with two hundred unsexed day-old Anak broilers was carried out to evaluate the effect of graded levels of toasted watermelon seed (WMSF) on carcass and internal organ characteristics of broilers. The proximate composition showed that toasted watermelon seed is rich in crude protein (34.78%) and ether extract (24.90%). Five experimental diets were formulated in which toasted WMSF replaced soyabean at 0, 10, 20, 30 and 40% tagged as diets 1, 2, 3, 4 and 5 respectively for both starter and finisher rations. The day-old chicks were randomly allotted to the dietary treatments with four replications each and 10 birds per replicate in a completely randomized design (CRD). At the end of the experiment two birds per replicate were randomly selected for carcass yield and organ characteristics. Most of carcass parameters measured were not affected except for eviscerated weight (1.18-1.56kg; P<0.05), heart weight, large intestine length and pancreas weight (P<0.01) as well as the weights of lungs, liver, kidney, large intestine and gizzard (P<0.01), though no definite pattern was observed. It can be concluded that inclusion of toasted WMSF in broiler diets at 30% has no adverse effects on the carcass yield and organ characteristics.

    EFFECT OF DIFFERENT PROCESSING TREATMENTS ON NUTRIENTS AND ANTINUTRIENTCOMPONENTS OF SENNA OCCIDENTALIS SEED MEAL
    (Department Of Science And Laboratory Technology, Nasarawa State University Keffi., 2016-04-09) Doma, U. D.; Nyako, H. D; Igwebuike, J. U; Augustine, C.; Dazala, I. U; Shuaibu, S.; Linus, S.
    A laboratory analysis was conducted to evaluate the effects of different processing treatments (boiling, soaking, sprouting and fermention) on the chemical composition of Senna occidentalis seed meals (SOSM). The entire representative processed samples were properly dried and milled. Each sample was analysed in triplicate for proximate composition, amino acid profile and levels of anti-nutritional factors using standard methods of analysis. Data obtained were subjected to analysis of variance of the completely randomized design and the treatment means were separated using Duncan multiple range test. The result revealed that the processing treatment significantly (P<0.05) affected the proximate composition of the seed meals. The proximate composition were observed to decrease in the differently processed seeds except for fermentation and sprouting where increase in the crude protein and ash contents of the seeds where observed. Similarly, the amino-acid profile showed significant (P<0.05) reduction except for the fermented seed meal which showed an increase in some of the amino acids content. The processing methods were observed to significantly (P<0.05) reduced the levels of the anti-nutritional factors withfermentation producingthe highest reduction effect. It can be concluded that fermentation was more effective in reducing the level of anti-nutritional factors and also in improving the nutrient content of Senna occidentalis seed meal. Based on the findings of this study, fermentation is therefore recommended for processing of Senna occidentalis seed meal. Further studies on processing the seed meal using integrated processing treatments such as soaking and boiling and two-stage cooking are required. Furthermore, fermented Senna occidentalis seeds should be used in a feeding trial with a view to ascertain the best inclusion level for domestic animals especially monogastric animals.
