The H5N1 strain of flu has been detected in flocks of chickens in at least 15 Vietnamese provinces, with possible cases in 10 others as well as in a few flocks in Japan and South Korea.
There were flashes and booms from tanks and Katyusha rocket launchers and, in the foreground, autumn wheat fields and a few flocks of longhaired black goats near the crumbling, fortresslike mud compounds of peasant farmers.
We noticed very few flocks of goats in the region being grazed along the roadsides.
We are at the early stages of this, but as the first few flocks of early employees and the founders start to move on, they are already spreading their post-Twitter wings and are in a position to exert a good deal of influence, both financially as well as in the formation of new businesses.
During the winter only ewes with lambs (and the few flocks that are in the high valleys) are stall-fed.
Here, we have investigated in detail the scrapie outbreak of one of very few flocks for which sufficient data are available for time course analysis.
A few flocks received an additional treatment in summer when necessary, and a low percentage of farms (2.72%) regularly administered two treatments.
The mortality rates reported were mainly based on studies conducted in single or a few flocks, which limits generalizability of the findings.
Different authors have observed that one or two additional case of AS have been found in only a few flocks in which all or most of the adult sheep in flock were examined for TSEs when culled due to the detection of an AS [ 16, 20, 26, 32].
Early detection is defined as the detection of an infected flock before it infects on average more than one other flock (between-flock reproduction ratio Rf < 1), hence a LPAI introduction will be detected when only one or a few other flocks are infected.
