Four coordinated, multisite production systems, each consisting of 1 MF farm that includes both gilts and pigs to produce replacement female stock, 1 GDU farm to raise replacement female gilts from 3 to ~26 weeks of age, and 4 BTW farms to raise pigs for meat, were selected to monitor the dynamics of IAV transmission in swine breeding herds.
On the GDU farms, 30 animals at <<26 weeks of age were sampled before movement to a BTW.
Bapco's Projects Engineering Department is currently executing the project - the total cost of which is estimated at $74 million - to instal seven new Khuff Gas Dehydration Units, as well connecting one Khuff gas well, to the Central
GDU at the onshore Bahrain Field as part of the 2007-2011 Khuff Gas Development Programme.
A Battery Computer Unit (BCU) is located at the Fire Direction Centre, while each gun under its control is equipped with a Gun Display Unit (GDU).
The GDU presents the calculated firing parameters to the artillery crews.
Growing degree units (GDU, [degrees] C) to 50% silk emergence were recorded on two replications at Ames in 1992, 1993, and 1994.
Cycle 0 through Cycle 10; FR, reciprocal full-sib: FS, full-sib: GDU, growing degree units, [degrees] C: HI, half-sib with inbred tester: [h.sup.2], heritability; MER, modified ear-to-row.
