Impacts of Egg Diets on the Culture of Clarias gariepinus Fry in Indoor Hatchery

The use of egg diets and fish meal as a starter diets for Clarias gariepinus fry after endogenous feeding was investigated for 42 days. The experiment was designed to determine the effects of egg diets on growth performance of C. gariepinus. The experimental diets were assigned into three treatments and control.

Antioxidant Enzyme Activities of the Leaves of Groundnut (Arachis hypogeae L.) Planted on Crude Oil-Contaminated Soil

ABSTRACT: Antioxidant enzyme activity of groundnut leaves planted in crude oil contaminated soil was evaluated. 1.5 kg of soil each was placed in black polythene bags. They were divided into four groups (A-D) of five bags each. Each group was treated with different concentrations of crude oil (0 ml, 5 ml, 10 ml and 15 ml per 1.5 kg soil respectively). five seeds of Arachis hypogaea were planted in each bag.

Variations by Sex and Genotype in Morphometry of the Oropharyngeal Cavity in Nigerian Indigenous Chickens

This study was conducted with the aim of studying the variations by sex and genotype in morphometry of the Oropharyngeal Cavity in Nigerian indigenous chickens. Avian mouth and pharynx do not show any definite line of demarcation, but constitute a common Oropharyngeal Cavity. Generally, anatomical structures found in the dorsal wall of the oropharynx include the palate, choanal slit, and infundibulum, while structures in the ventral wall of the Oropharynx include a concave depression between the rami of the lower beak, laryngeal mound and glottis.

Comparative Histomorphological Studies on the Thyroid Gland of Red Sokoto and Sahel Goats during Prenatal Period of Development

ABSTRACT: The present study was done to compare histological developmental features of the thyroid gland in Red Sokoto (RSG) and Sahel Goats (SG) during prenatal periods. A total of 90 fetuses and 60 postnatal heads and necks of the two breeds were used for the study.  Both periods were categorized into three age groups.
