Fourteen percent used artificial insemination (AI) and 30% used both AI and natural service for breeding.
In total, 6 cases (22%) of delayed uterine clearance/endometritis were noted after the 27 AIs performed with fresh or frozen/thawed semen, either for pregnancy or for embryo collection, while 7 cases (54%) of endometritis were diagnosed after the 13 natural services performed by the stallion for the establishment of pregnancies or for embryo collection.
All mares were examined after AI or natural service (NS), for uterine pathologies.
Heifers were exposed for natural service beginning 14 d after AI for the remainder of a 60 d breeding season.
The lame herd sire, unsound for breeding, can cause substantial economic loss [ 1], especially when the bull is used for natural service.
Future studies should investigate whether semen could be a real source of CA infection by determining if the agent may be transmitted during natural service or when semen is used for artificial insemination.
A1 Natural Gas Shut-Offs Delactivistsuniny aChicagosaid Chicago said Peoples Gas had agreed to delay shut-offs of natural gas service for delinquent customers while talks continued with the Rev. Jesse Jackson and local community leaders.
The ONEOK Partners segment involves the gathering, processing, storage and transportation of natural gas in U.S. The Energy Services segment provides natural gas supply and risk-management services for natural gas and electric utilities and commercial and industrial customers.
The program, launched in September 2001, focuses on reform of electric power markets, the geopolitical consequences of newly emerging global natural gas markets, energy services for the world's poor, and managing climate change and other environmental consequences of modern energy systems.
Let's see now: Wisconsin has nearly one million natural gas customers, so it would presumably be a company that "provides consulting, engineering, design, procurement, fabrication and construction services for the natural gas and gas processing industries worldwide" and has "been the general contractor on some of the largest natural gas plants built in the U.S".
There has been a natural movement of goods and services for hundreds of years.
