Correspondence to Michael Hofreiter or Xingbo Zhao. The trend was for developing herds that produced higher numbers of offspring and pigs that were leaner resulting in better feed efficiency.
Husbandry methods emphasized control of diseases caused by huge factory pig-raising techniques, introducing the use of prophylactic antibiotics. Pork had become "the Other White Meat", and although production was more efficient and cost-effective, the taste was steadily being bred away. Now the trend is toward a return to the older, fattier, tastier heritage breeds such as the Berkshire, the Red Wattle, the Tamworth, the Large Black, the Mule Foot, the Old Spot, and the Ossabaw a direct descendent of the original Iberico black-footed hogs imported by the Spaniards to Savannah, Ga.
Their meat has superior taste and texture, with marbling that retains the moisture of the meat. There is also a greatly increased demand for small farm, pasture-raised, organically grown pigs, and rejection of methods such as water-injection for finished pork. A happier pig is a tastier pig!

The pig dates back 40 million years to fossils which indicate that wild porcine animals roamed forests and swamps in Europe and Asia. Remains of the earliest known North American peccary, Perchoerus , are from late Eocene sediments dating from 37 million years ago in North America. But it's the domesticated pig that holds our interest. The Romans improved pig breeding and spread pork production throughout their empire.
Two main types were developed: one breed was large, with floppy ears, and produced copious amounts of lard, while the other was of a smaller frame, with erect ears, used primarily for meat.

Females travel in groups, called sounders, usually of 2 to 20 but up to 50 individuals, including one or more sows, their piglets and maybe a few adoptees. Since the only thing besides food they cannot do without is water, they make their homes in bottomlands near rivers, creeks, lakes or ponds.
They prefer areas of dense vegetation where they can hide and find shade. Porter stops to let his own two dogs out of their pens in the bed of the pickup and they, too, are off in a flash.
When the truck reaches the area where the pigs had been, Porter, his partner Andy Garcia and I hear frantic barking and a low-pitched sighing sound. Running into the brush, we find the dogs have surrounded a red and black wild hog in a clearing.
Two dogs have clamped onto its ears. The dogs back off and quiet down as he grabs its rear legs and drags it back to his truck. Stewart and his hunting and wildlife manager, Craig Oakes, began noticing wild hogs on the land in the s, and the animals have become more of a problem every year.
Many hunters prefer working with dogs. Two types of dogs are used in the hunt. Bay dogs—usually curs such as the Rhodesian Ridgeback, black-mouth cur or Catahoula or scent hounds such as the foxhound or Plott Hound—sniff out and pursue the animals. A hog will attempt to flee, but if cornered or wounded will likely attack, battering the bay dogs with its snout or goring them with its tusks. Some hunters outfit their dogs in Kevlar vests.
Catch dogs grab the bayed pig, usually at the base of the ear, and wrestle it to the ground, holding it until the hunter arrives to finish it off. Dogs show off their wild-hog skills at bayings, also known as bay trials, which are held most weekends in rural towns across Texas. A wild hog is released in a large pen and one or two dogs attempt to bay it, while spectators cheer. Occasionally bayings serve as fund-raisers for community members in need. Ervin Callaway holds a baying on the third weekend of every month.
His pen is down a rutted dirt road off U. His son Mike is one of the judges. We count off any distractions, a tenth of a point for each. When it tries to move away, a young man uses a plywood shield to funnel it toward the dogs. They stop less than a foot away from the hog and make eye contact, barking until the animal shoots between them toward the other side of the pen. As the dogs close back in, the hog swerves hard into a fence, then bounces off.
The smaller dog grabs its tail but is spun around until it lets go. The pig runs into a wallow and sits there. The yellow dog bays and barks, but from maybe three feet away, too far to be effective, and then it loses concentration and backs off. The pig exits through the chute. Neither dog scores well.
Several states, including Alabama, Mississippi, South Carolina and North Carolina, have outlawed bayings in response to protests from animal rights groups. That five-day event began in and draws about 10, people annually.
The event was canceled because of disputes among the organizers. But bayings continue to take place on a smaller scale elsewhere, as do bloodier hog-catch trials in which dogs attack penned-in wild hogs and wrestle them to the ground. The legality of both events is in dispute, but local authorities tend not to prosecute. A local prosecutor would have to argue these things, and so far nobody has.
Quaca, 38, began rifle hunting when he was 4 years old but switched to bowhunting at age He likes the silence after the shot. As a teen, he eagerly helped neighbors clear out unwanted hogs.
