  Background and Objective: The leaves of many tropical plants are habitually given to animals as fodder without adequate knowledge of the nutritional and pharmacological compositions that generate their desirable effects. The objective of this study was to evaluate the phytochemical characteristics of leaf meals of Garcinia kola, Gongronema latifolium and Mucuna pruriens as candidate nutraceuticals in animal production. Materials and Methods: They were collected from surrounding farmlands and bushes at Ihiagwa, Owerri west Local Government Area (LGA) of Imo state, Nigeria. The leaf meals were subjected to physicochemical characterization to determine their bulk density (BD), water holding capacity (WHC), specific gravity (SG), proximate composition, metabolizable energy, fibre fractions, minerals and secondary metabolite concentrations. Results: The G. latifolium had higher bulk density than M. pruriens and G. kola, while G. kola had higher water holding capacity (WHC) value. The G. latifolium yielded highest crude protein, crude fat, total ash and metabolizable energy values, while for crude fiber contents of M. pruriens yielded the highest. Conclusion: It is therefore, concluded that G. latifolium, G. kola and M. pruriens are endowed with essential nutrients and bioactive substances.

  Consumption of saturated and trans fats can elevate blood cholesterol levels thereby increasing the risk of heart disease. Excessive fatty deposit associated with broiler meat due to ad libidum feeding has been reported to affect the quality of the processed chicken. There has been reports that different herbs and natural products are effective in lowering serum cholesterol levels in animals thereby producing leaner and healthier broiler meat. In view of recent concerns on effects of bad lipids on human health and claims that the supplementation of broiler diets with Moringa oleifera seed meal might positively affect the carcass quality, this study was initiated. This trial evaluated the effects of feeding undecorticated Moringa oleifera seed meal on growth performance, haematological and biochemical values of broilers finisher birds. The air dried seeds were milled in a hammer mill to produce Moringa oleifera Seed Meal (MOSM). Four broiler diets were formulated to contain the MOSM at 0, 8, 12 and 16%, respectively and were used to feed 96 broiler finisher birds. The birds were divided into 4 groups and randomly assigned to the 4 treatment diet with to as control diet and T1, T2, T3 as the Moringa treatment diet in a Completely Randomized Design (CRD) with 3 replicates per treatment. Water and feed were provided ad libitum. At the end ofn the experiment, six birds per treatment were randomly selected for collection of blood samples for haematological analysis. Blood samples were collected and dispensed into tubes containing Ethylene Diamine Tetra Acetic acid (EDTA) as anticoagulant and another set into tubes without coagulant for serum analysis. At the end of the 7 week experimental period, results indicated that Average Final Body Weight (AFBW) and Average Daily Weight Gain (ADWG) decreased significantly (p<0.05) with increased inclusion of Moringa oleifera Seed Meal (MOSM), although, T2 showed least value in ADWG. The results showed that haematological indices such as packed cell volume, red blood cells, mean cell volume, mean cell haemoglobin, haemoglobin were not significantly (p>0.05) influenced by varied levels of MOSM and were within the normal range (9.06-31-0×106/g) recommended for broiler birds except for WBC, lymphocyte, neutrophiles and platelets which were higher than the average values. The results of the biochemical parameters indicated that urea was significantly (p<0.05) influenced by increasing levels of MOSM compared to the control. However, elevated values of serum cholesterol, sodium, chlorine, glucose and calcium were observed, although, not significant. All other serum indices were not significantly (p>0.05) influenced by increasing levels of MOSM. The study suggests that the dietary inclusion of MOSM significantly reduced weight gain but did not reduce the serum cholesterol levels in the broiler birds.
