ABSTRACT
The increasing human exposure to dichlorvos (DDVP) and its toxicity is a growing public health concern. This work was aimed at studying the therapeutic effect of Vernonia amygdalina, Ocimum gratissimum, Talinum triangulare extracts against DDVP induced hepatotoxicity in rats. Total of 50 male adult rats of average weight 272g were placed in ten groups (n=5) and orally administered normal saline (normal control), 8.0mg/kg body weight DDVP (positive control), 8.0mg/kg body weight DDVP + 200mg/kg and 400mg/kg body weight of the plant extracts and 20 mg/kg body weight and 40 mg/kg bodyweight of vitamin C for 28 days. DDVP significantly (P<0.05) increased Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Alkaline phosphatase (ALP) and Gamma glutamyl transferase (GGT) when compared with normal control. Treatment with aqueous leaf extracts of Vernonia amygdalina, Ocimum gratissimum, Talinum triangulare significantly reversed the distortions in the values of biochemical parameters when compared with positive control. Photomicrographs obtained from histological examination of liver tissues corroborate these findings. Aqueous leaf extracts of Vernonia amygdalina, Ocimum gratissimum, Talinum triangulare may have therapeutic potentials to DDVP induced hepatotoxicity in rats.

ABSTRACT
A feeding trial was conducted to determine the effects of black pepper, tumeric, corriander and their blend as supplementary phytoadditives in dosage 1 kg per ton of feed on the growth performance and meat sensory assessment of broiler chickens. A total of three hundred (300) day-old broiler chicks were used for the study. At the starter phase, the chicks were weighed at day old and randomly assigned to five dietary treatments in a completely randomized design (CRD). Feed and water was provided ad libitum during the trial period. The birds were weighed at the beginning of the trial and weekly thereafter. Weight gain, feed intake, left over feeds were measured and recorded, feed conversion ratio and feed cost per kilogramme weight gain were calculated and mortality rate recorded as they occurred. Medication and vaccine administration was carried out as required. Performance parameters calculated include feed intake, weight gain, feed to gain ratio, feed cost per kilogram gain and mortality. For the finisher phase, one hundred and five four weeks old chicks were allotted to five dietary treatments in a completely randomized design (CRD). The treatments were replicated three times with fifteen chicks per replicate. Performance parameters measured were the same as for the starter phase. The experimental study lasted seven weeks. Data obtained were subjected to analysis of variance using SAS (2008), while the significant differences between treatment means were separated by Duncan Multiple Range Test at a 5% level of significance. There were significant (p<0.05) differences in final weight, weight gain, feed consumption, feed conversion ratio, feed cost per gain and mortality. Birds fed corriander supplemented diet (T4) had significantly (p<0.05) higher final weight, weight gain and least cost of production which were at par with birds fed black pepper supplemented diet (T2). The least performance was observed for birds fed black pepper, tumeric and corriander ..........
