Effects of lead pollution against juvenile Achatina achatina fed on contaminated artificial diet.

We investigated juvenile Achatina achatina snails by feeding graded levels of inorganic lead metal contaminated artificial diet in plastic snaileries in the laboratory. Snails were tolerant of all levels of lead contamination with no mortalities. Results indicated significant (p < 0.

Effects of lead pollution at industrial contaminated sites on sentinel juvenile Achatina achatina.

We investigated juvenile Achatina achatina snails exposed as sentinels in plastic cages for 12 weeks to compare lead pollution at dump sites of abandoned battery factory (Niger Delta, Nigeria). Results indicated 0.56, 20.

Effects of lead pollution from vehicular exhaust fumes against sentinel juvenile Achatina achatina.

We investigated lead metal pollution induced by traffic fumes along roads with differing traffic intensity near abandoned battery factory (Niger Delta, Nigeria). Juvenile Achatina achatina were positioned as sentinels in plastic snaileries 2 m on road sides. Lead contamination in snail tissue by atomic absorption spectrophotometer increased with increasing vehicular traffic intensity.

Performance and histological responses of internal organs of broiler chickens fed raw, dehulled, and aqueous and dry-heated kidney bean meals.

The objective of the present study was to investigate the effect of raw and differently processed [aqueous heating, dehulled, and dry heating (toasted)] kidney bean meals on the performance, weights, and histology of internal organs of broiler chicken. The feeding trial lasted for 56 d. Two hundred twenty-five 1-d-old broiler chicks (Anak strain) were used for the study.

Histological alterations in the internal organs of growing chicks from feeding raw jackbean or limabean seeds.

The effect of raw jackbean (Canavalia ensiformis) or limabean (Phaseolus lunatus) seeds at 0, 250 or 500 g/kg in broiler chick diets for 28 d on performance and cytopathological changes in internal organs was evaluated. Relative pancreas weight increased significantly (P < 0.05) and the lungs had severe atelectasis, thickening of the alveolar septa and bronchiolar epithelial hyperplasia.
