A total of one hundred and seventy-three fertilized eggs were used for morphometry, gross and histological studies. At day 4 of incubation, the mean body weight of the helmeted guinea fowl embryo was 0.6401 ± 0.0211 g. It was at day 10 of incubation that there was an increase in the whole body weight of the embryo to be 0.8650 ± 0.676 g. The whole brain weight indicated relative increased at day 4 as compared to that of the whole body weight. Graphically, there were steady increase in the body, brain and optic lobe weights. Histologically, cells and neurones that make up the optic lobe is probably as a result of the migration of immature cells from the ventricular neuroepithelium.

<p class="jbls"><span lang="EN-GB">Apparently healthy wild gray guinea savannah squirrel, totaling fourteen (14) in number were used for this study. After being captured from the wild, they were kept for two weeks before they were sacrificed. Weight and length of the whole animal, gastrointestinal tract (GIT) and stomach were taken and recorded in gram (g) and centimeter (cm). The mean weight of live animal was 380.04 ± 46.00 g with the GIT counting for 9.97 % of the total body weight. The mean weight and length of the stomach were 1.59 ± 0.36 g and 4.00 ± 0.61 cm, accounting for 0.42 % and 2.94 % respectively. Externally, the stomach was gray-whitish in fresh sample, bean-shaped, covered almost entirely by deep pink like coloured liver ventrally. The interior surface is grayish with non glandular portion around the cardiac area and longitudinally folded glandular portion. Areas of sphincters were recognized as pyloric, toward the intestinal point of attachment to the stomach and cardiac sphincter toward the point of attachment of the esophagus. More folding was noticed toward the pyloric region indicative of food storing and distension capability of the stomach.</span></p>
