This study was conducted to determine the effect of egg size and strain on growth performance of cockerel chicks obtained from Dominant Black (DB) and Yaffa Brown (YB) strains of pullet. A total number of two hundred and seventy day-old cockerels hatched from three different egg sizes (i.e 45 chicks from small, medium and large egg sizes for each of DB and YB) were used for this study. Data obtained were subjected to analysis of variance in a 2 x 3 factorial experimental layout. The initial weight of the chicks was significantly (P<0.05) influenced by the egg size. Final weight and average daily weight gain were the only growth parameters affected (P<0.05) by egg size till the end of starter phase. The effect of strain on all the growth parameters measured were not significantly (P>0.05) different. At the growing phase, feed intake decreased significantly (P<0.05) with increase in egg size. It was concluded that setting of medium and large egg sizes could only be beneficial if the target was to sell chicks of the two strains at the end of chick phase.

The fruit of Lagenaria breviflora R. was obtained and subjected to methanol extraction. The chemical compound in the extract was analyzed using a Gas chromatography coupled with mass spectrophotomter (GC-MS). The screening of the fruit extract revealed important phytochemicals such as Phenols, Alkaloids Carotenoids and Flavonoids. The analysis of the GC-MS revealed that hydrocarbons as the most abundant compound in the extract and a total of 30 compounds were identified. The major components are octadecane (19.25%), hexacosane (10.9%), docosane (9.15%0, 2 methyl-E,E-3,13- octadecadienol (8.33%), heptadecane (8.18%), tricosane (4.36%), tridecane (3.71%), 1,2-Benzenedicarboxylic acid, mono (2-ethylhexyl) ester (3.63%), tetracontane, 3,5,24-trimethyl- (3.38) and 9,12-Octadecadienoic acid (Z,Z)- (2.64%). Some of the compounds obtained have been reported to have potentials for prophylactic and therapeutic treatment of diseases in both man and animals.
