  A Total of one hundred and twenty broiler chickens at five weeks old were used in an experiment to determine the responses of broiler chickens fed varying levels (0,5,10, 15%) of dietary supplement of Telfaira occidentalis leaf (pumpkin leaf) meal. The experiment was laid out in a completely randomized design having four treatment groups and each treatment group was replicated thrice with each replicate having a total of ten birds. Birds were fed and watered ad libitum and the study lasted for 28 days. Results obtained showed that daily body weight gain (g) were significantly (p<0.05) influenced by 10 and 15% experimental diets supplementation, having depressed body weight gain compare with 5% level of supplementation and the control diets that were similar in terms of body weight gain. Feed conversion ration were similar in all the experimental groups, however, mortality was highest in the control group. No significant differences (p>0.05) were observed for the groups with respect to all the internal organs measured, with the exception of the small and large intestine. The longest small intestine (which was thus significant, (p<0.05) were recorded in the 10 and 15% group when compares with the control and 5% treatment groups. Similarly, the large intestine was significantly (p<0.05) longer in all the test diet supplemented with T. occidentalis leaf meal. Haematological parameters assessed shows that significant (p<0.05) difference existed in Parked Cell Volume (PCV%), mean corpsular haemoglobin (MCH p g-1) and Mean Corpuscular Haemoglobin Concentration, (MCHC g dL-1). The lowest values were observed in the control group which was significantly (p<0.05) lower compare with those broiler chicken offered T. occidentalis leaf meal. It was concluded that 5% level of dietary supplementation with sun dried T. occidentalis leaf meal gave the best result.

  Biochemical and relative organ changes of rabbits fed with Chromolaena odorata Leaf Meal (COLM) were studied. A total of 32 rabbits consisting of 17 males and 15 females and of mixed breeds, aged 6-8 weeks and weighing 400-800 g were randomized into four diet groups of 0, 10, 20 and 30% in a completely randomized design for 56 days. Each treatment was replicated 4 times with two rabbits per replicate. Samples of blood were collected weekly from the ear vein for biochemical studies and the relative organ changes were determined using an electronic weighing scale. Results of biochemical analysis showed that the serum urea concentration was significantly (p<0.05) higher at an increasing level of COLM. Total cholesterol, triglycerides and LDL were found to significantly (p<0.05) decreased at increasing rate of COLM with the lowest level at 20 and 30% and corresponding to a value of 55.0 mg dL-1 at 20%, 25.0 mol L-1 at 30% and 22.5 mol L-1 at 20% for total cholesterol, triglycerides and LDL, respectively. As the rate of COLM increases, significant decrease was also observed in serum albumin concentration. Significant (p<0.05) increase observed in HDL was higher at 20% (60.5 mol L-1) than at 0% (42.0 mol L-1), 10% (24.0 mol L-1) and 30% (49.5 mol L-1) diet groups. Treatment with C. odorata significantly (p<0.05) prevented the elevation of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) with the lowest value at 10% for both serum transaminase. Results of relative organ changes showed higher significant (p<0.05) difference in the kidney and heart weight. However, significant decrease was observed in lungs and spleen weight at an increasing level of COLM. These results revealed that C. odorata may be safe and non-toxic only at a level that does not exceed 10% in the diet of rabbits.
