Na one of di most controversial practices for agriculture be dis: to dey give small small antibiotics to animals so dem go grow quick quick. But wetin if di drugs sef no dey work well? E get some good evidence say dem no dey work well, at least for pigs. Dem dey use to make di pigs grow fast before, but e be like say di effect don disappear or reduce well well for recent years. Di reason for dis dey interesting and even paradoxical. Researchers believe say di antibiotics use to work by suppressing low-grade infections. But for recent years, pork producers don find other ways to achieve di same thing through better hygiene. As e be so, di drugs don almost no dey useful again -- but many farmers still dey use am.

To understand how dis whole thing take happen, you gats waka back for time, Steve Dritz, wey be specialist for pig nutrition for Kansas State University talk. Sixty years ago, when antibiotics dey new, "people start dey treat animals, and dey give dem [the antibiotics], and dem dey see say di animals dey grow fast and dey use feed well," he talk. For example, nursery-age pigs, dem dey grow 12 to 15 percent faster with antibiotics. Di animals sef no dey need plenty feed to reach full weight. Other studies show similar results for chickens and cattle. For di 1980s, new studies come see similar effects. So di growth-promoting effects of antibiotics come become standard practice among meat producers.

Fast forward reach di 1990s. Dritz dey start im career as scientist for Kansas State University, and pork production dey change well well.

Before before, pigs dey born and dey raise for one barn or for several barns wey dey close to each other. Dis one mean say infections fit easily pass from one generation to di next, just like how pikin dey share germs between dia friends for playground and dia parents for house. Under di new system, when piglets dey weaned, dem go move go different place. Dis new place go dey carefully clean and free from disease.

Craig Rowles, wey dey run big swine operation for Carroll, Iowa, show me one room like dat. No piglet dey sight. "Dis room just dey wash and dey disinfect, and e go dey here dey dry small small," he talk.

A whole group of pigs go enter dis place together, and later dem go move go another place. "Dis group of pigs go dey together until dem go market," Rowles talk.

Dem dey keep di groups strictly separate from each other. If workers wan move between di groups, dem go first change dia boots.

When farmers begin use multisite production, e reduce disease well well -- and di pigs sef dey grow faster.
