This experiment was carried out to investigate the effect of supplementing different levels of Spondiasmombin leaf meal on the performance and blood profile of broiler chickens. Experimental parameters covered growth performance and some heamatological and blood serum analysis. One hundred and sixty, day old Arbo acre broiler chicks were randomly divided into four treatments groups with four (4) replicates, each of ten birds in a Completely Randomized Design (CRD). Group 1 was fed basal diet without Spondiasmombin leaf meal (SSM), Group 2, 3 and 4 were fed basal diets supplemented with SSM at levels of 1.0%, 2.0% and 3.0% respectively. The basal diet was formulated to meet the nutritional requirements of broilers according to NRC (1994), the experiment lasted for 49 days and the results obtained showed that there were significant ( P<0.05) differences among all treatments in the values of final live weight and feed conversion ratio. No significant difference (P>0.05) was observed for the daily feed intake of the birds. Results for heamatology showed that white blood cell counts, RBC, Hb and PCV were significantly (P<0.05) affected with the inclusion of Spondiasmombin leaf meal, SGPT, SGOT and other serum parameterswere not significantly different (P>0.05) during the experiment. No mortality was recorded throughout the experimental period. Results obtained from this study showed that Spondiasmombin leaf meal is a good source of plant vitamins and minerals and its inclusion at 3.0% level does not have any deleterious effect on the general performance and health status of broiler chicken.

An experiment was conducted to assess the influence of GGO on carcass features and sensory assessment of broiler chickens. 120 1-day-old (Arbo acre) birds were separated into five treatments, each with three replicates of 8 birds. Throughout the 8-week trial, clean feed and water were available at all times. NRC's basal diet was designed to suit avian nutritional needs (1994). A 0% GGO meal was given to the birds in treatment 1, whereas GGO levels of 0.1, 0.2, 0.3 and 0.4 percent were given to the birds in treatments 2, 3, 4, and 5. As well as studying the phytochemical content of (Zingiber officinale) and garlic (Allium sativum) oil, carcass and organ features of birds were also studied. Zingiber officinale contains phenols (8.21%), alkaloids (5.12%), flavonoids (7.49%), tannins (6.52%), saponins (3.18%), streiods (2.38%), glycosides (0.18%), oxalates (0.07%), and phytate (0.07%). (0.02 %). Sativum contains flavonoids (10.67%) alkaloids (7.02%) tannins (4.72%) steroids (3.65%) saponin (2) glycoside (0.33%) oxalates (0.26%) and phytate (0.26%). (0.05 %). Dressing %, carcass and relative organ weights differed across treatments (P0.05). The liver, kidney, spleen, and other internal organs showed no signs of inflammation. GGO altered meat sensory assessment (tenderness, juiciness, taste, and fragrance) except meat color which was not significantly (P0.05) different across treatments. GGO may be fed to broilers up to 0.4 percent without affecting their health or performance.

Medicinal plants are used to prevent, treat and promote healthy life in human and animals, their medicinal value are due to the presence of bioactive chemicals or secondary metabolites (phytochemicals) making it more suitable for animals with benefits of low cost and total safety. Phytochemicals are chemical compounds that occur naturally in plants and they perform a multiple biological activities such as: antibacterial, antioxidants, anti-inflammatory, antioxidants, antifungal, hepato-protective, hypolipidemic and antiviral properties. The efficacy of phytochemicals in plants depends on their organic composition (tannin, flavonoids, terpenoids, saponin, phenols and alkaloids), method of extraction or processing, harvesting procedure, soil type, geographical location and level of maturity. Plants are also found to be loaded with minerals, vitamins and other nutrients needed for the growth and development of animals.

This experiment was conducted to evaluate the growth performance and some hemato-biochemical parameters of broilers fed different levels of Pakia biglobosa leaf extract (BPE). Two hundred and fifty (250) one day old (Ross 308) broiler chicks were randomly assigned to five treatments with five replicate consisting of ten (10) bird each in a completely randomized design. Treatment 1 contained 0% BPE, Treatment 2, 3, 4 and 5 contained 5ml, 10ml, 15ml and 20ml per liter of water respectively. Clean feed and water were offered ad libitum throughout the experiment which lasted for 7 weeks during which data on performance, hematology and serum biochemical traits were collected. Results revealed that BPE had a significant (p<0.05) effect on final weight, feed conversion ratio and mortality rate. Birds given 20ml (T5) BPE recorded the highest weight gain (1846.1g) followed by 15ml (T4) with 1839.1g, 10ml (T3) with 1763.1, 5ml (T2) with 1757.1g and 0ml (T1) with 1679.0g respectively. BPE had no significant (p>0.05) on the feed intake of the birds. There was no significant (p>0.05) difference in PCV, Hb, RBC, MCV, MCH and MCHC values among the treatment. However, WBC and its differentials were significantly (p<0.05) influenced by BPE. Significant influences were not observed for albumin, globulin and total protein. Serum glutamic oxaloacetate transaminase (SGOT) and Serum glutamic pyruvic transaminase (SGPT) were significantly affected (P<0.05) as the level of BPE increased in the water of the animals. It was concluded BPE can be safely included in the water of birds at 15ml and 20ml without any deleterious effect on the performance and health of the animals.

This study was conducted to examine the growth performance, nutrient utilization and haematological characteristics of broiler chickens fed diets supplemented with Azolla-Moringa Oleifera mixture. One hundred and sixty (160) Arbo-acre day old chick of mixed sex was divided into four groups with four replicates, each of ten birds in a completely randomized design. Treatment 1 was fed basal diet without Azolla -Moringa mixture (MLMAZP), treatment 2, 3 and 4 were fed basal diets supplemented with MLMAZP at levels 5, 10 and 15% respectively. Proximate analysis shows that Azolla powder contained 22.51% crude protein, 3.53% ether extracts, 14.13% ash, 18.15% crude fibre and 37.88% nitrogen free extract while Moringa Oleifera leaf meal contained 27.51% crude protein, 2.23% ether extracts, 7.13% ash, 19.25% crude fibre and 43.88% nitrogen free extracts. The basal diet was formulated to meet the nutritional requirements of broilers according to NRC (1994). The results shows that there was a significant (P<0.05) difference in the final live weight, feed conversion ratio, carcass/dressing percentage and daily water intake. However, no significant influence (P>0.05) were observed for feed intake and some of the hematological parameters measured (PCV, Hb, RBC, WBC, MCV, MCH and MCHC). No mortality was recorded throughout the experimental period which lasted for 42 days. It can be concluded based on data from performance, nutrient utilization and hematological parameters that MLMAZP can be added up to 15% in the diets of broiler chickens.
