Blood samples are taken from piglets on day one after birth, mixed with ammonia sulfate to precipitate immunoglobulin, put into a microcapillary tube, and spun so the precipitated immunoglobulin settles to the bottom.
Silver City and Grant County offer a little of everything: from quiet fly fishing in genuine mountain wilderness, rocking blues and music festivals in a historic downtown, off-road motor touring across hundreds of miles of scenic roads and lots more.
In 1928 the town became the northern terminus of the Fort Worth and Denver South Plains Railway from Lubbock. Silverton was subsequently incorporated, and it grew. Natural gas was introduced in 1929 by the West Texas Gas Company. By 1940 Silverton had thirty-five businesses and a population of 684. Throughout its history Silverton has suffered from prairie fires, grasshoppers, dust storms, and cyclones. Its worst disaster occurred on the night of May 15, 1957, when a tornado killed twenty-one people and did over $1 million worth of damage.
