The influence of a slow-release multi-trace element ruminal bolus on trace element status, number of ovarian follicles and pregnancy outcomes in synchronized Afshari ewes

Published data on the effects of ruminal bolus on the number of ovulatory follicles in ewes does not exist. The present study determined the effects of a ruminal bolus on trace element status, follicular dynamics and reproductive performance in ewes. Eighty Afshari cycling ewes were synchronized during breeding season using CIDR for 14 days and assigned to 4 groups (n=20); group 1 received a si...

Trace Element Chemistry Studies

This work was undertaken to measure background silver in Illinois precipitation in the absence of any known seeding operations in or near Illinois. The overall rainfall-weighted mean concentration at several stations was 73 ng/liter. This is somewhat higher than has been found in unseeded precipitation in the western United States, but probably not high enough to preclude identification of silv...

Ocean trace element cycles.

The oceans are salty. Each litre contains about 35 g of dissolved salts, resulting from the balance between inputs and outputs to the ocean over geological time. The constituents of common salt—Na and Cl—make up more than 90% of this dissolved mass, and together with Mg, S and Ca, represent 99%. Add only three more elements— K, Br and C—and you have more than 999 parts in a 1000 of the dissolve...

Trace element accumulation in lotic dragonfly nymphs: Genus matters

Constituents of coal combustion waste (CCW) expose aquatic organisms to complex mixtures of potentially toxic metals and metalloids. Multi-element trace element analyses were used to distinguish patterns of accumulation among 8 genera of dragonfly nymphs collected from two sites on a CCW contaminated coastal plain stream. Dragonfly nymphs are exceptional for comparing trace element accumulation...
