  A new antibacterial ester (1), 2-O-butyl-1-O-(2-ethylhexyl) benzene-1,8-dicarboxylate and a ketone (2), 1-phenyl-1,4-pentanedione was isolated from Vitellaria paradoxa (G.Don) heper by directing the fractionation of an ethanol extract of the air dried root bark with bacterial sensitivity assay. The structures of 1 and 2 were determined from 13C-NMR, 1H-NMR, DEPT, IR and GC-MS spectral data. The two compounds were found to be active against gram positive Bacillus subtilis and Staphylococcus aureus and gram negative Escherichia coli, Salmonella typhi and Pseudomonas aeruginosa. The isolation, structural elucidation, NMR spectral assignment and bioactivities of compounds 1 and 2 are reported.

  The experiment was conducted with the aim of investigating effects of breed and age on carcass and lean quality characteristics of goats in the study area. To achieve the aim, a total of 32 intact bucks, matching condition score “3” of the Australian Standard for Live Goat Evaluation were balanced for weight across 8 replicates of 2 breeds (Sokoto Red and Sahel) and 2 age treatments (Young and Mature). Animals were bled by slashing their throats to sever the jugular, the carotid, the trachea and the oesophagus. After bleeding, the animals were partially skinned lying on their backs on the floor. Thereafter, the animals were suspended by the hind legs on a 14 cm wide gambrel for further skinning. The head was removed at the atlanto-occipital joint and the fore and hind feet removed at the carpal and tarsal joints respectively. Breed had no effect (p>0.05) on any of the traits investigated. Also, feathering, flank streaking and marbling were not affected by age (p>0.05). However, mature goats recorded significantly higher values (1.438, 1.625, 1.750, 1.812 and 1.625) for flank firmness, kidney fat score, subcutaneous fat score, lean texture and lean firmness respectively. Corresponding figures for young animals were 1.062, 1.125, 1.062, 1.000 and 1.188. It was observed that goats in the study area have poor carcass fat deposition.

  This study was conducted to investigate in vivo antimicrobial potential of garlic against Clostridium perferinges and resultant promotant effects on performance of the broiler chickens. Garlic powder was used as an alternative to GPAs (Growth Promotant Antibiotics) to prevent subclinical Necrotic Enteritis (NE) due to C. perferinges. 120 day-old broiler chicks were randomly distributed to six treatment groups of 20 chicks each (2 replicates¯10 chicks). Six isonutrient diets supplemented with garlic at graded levels of 0.0, 0.5, 1.0, 1.5, 2.0 and 2.5 g kg-1 were fed to the birds for seven weeks. Data were collected weekly on performance parameters including feed intake, weight gain and feed conversion ratio (FCR). Also, on the 21 35 and 49th days of the study, two birds per group were randomly selected, slaughtered and dissected. 1g of caecal contents per each bird were sampled into labelled sterile sample bottles. The samples were subjected to culturing, bacterial identification and colony counting. All data were subjected to analysis of variance. Results showed that garlic significantly (p>0.05) depressed feed intake (3310 g feed/bird at 1.0 g kg-1 supplementation) but improved FCR. The supplement has no significant effect on weight gain but C. perfringens colony counts in the treated groups, were numerically reduced (lowest count, 0.93x105 cfu g-1 at 1.0 gkg-1 supplementation), as compared to the control. It is therefore concluded that diets could be supplemented with garlic at dose range of 1.0 to 1.5 g kg-1 to prevent subclinical NE and achieve improved performance in birds.
