Heritage Turkey Production Research: It's Profitable But More Difficult

 

To meet increasing consumer demand for heritage-breed turkeys to be the centerpiece of holiday and other meals, researchers in Penn State's College of Agricultural Sciences are studying methods producers can use to raise the historical birds.

 

Having more in common with wild turkeys that roam fields and forests than birds currently sold in grocery stores, heritage turkeys — in the relatively few retail outlets where they can be found — sell for about four times the cost of the broad-breasted white turkeys commonly found in store freezers. The average store-bought turkey costs about $1 per pound, while heritage turkeys run between $4 and $6 per pound.

 

These birds proportionally have much smaller breasts, darker leg meat and are generally gamier in flavor than broad-breasted whites raised on large, modern poultry farms. Heritage birds are also typically older than faster-growing, broad-breasted birds at the age of processing — 26 to 28 weeks compared to 14 to 18 weeks — which can result in a more textured or flavorful meat.

 

Heritage does not mean organic, all-natural or free-range, though a true heritage bird may be all of those things, noted Paul Patterson, professor of poultry science, whose research group is studying alternative production methods. "Heritage," he explained, refers to specific breeds of turkeys raised in the United States prior to the 1950s, when the poultry industry began the cross breeding that resulted in the broad-breasted white turkeys most people eat today.

 

The heritage breeds include the Standard Bronze, Bourbon Red, Narragansett, Jersey Buff, Slate, Black Spanish, White Holland, Royal Palm, White Midget, and Beltsville Small White.

 

Heritage birds differ from broad-breasted whites in a number of ways: They are lighter in weight, leaner, with less muscling, and dark or colored feathers. Broad-breasted turkeys have been bred to grow so big that they have trouble reproducing on their own and therefore, they must be artificially inseminated.

 

"Heritage birds, which are more athletic, can perch, fly and reproduce naturally, but are more expensive to raise," Patterson said. "However, because the market for them is growing and consumers are willing to pay so much more for them, there is considerable interest in producing more. As we have looked into this market, I am shocked at the prices people are getting for these heritage birds."

 

But the more naturally raised heritage turkeys desired by consumers are not produced the way broad-breasted whites are in commercial poultry operations, and Patterson's research group is experimenting with novel production methods to raise the birds. Findings from the first phase of the project, incorporating natural feedstuffs into heritage turkeys' diet, will be presented at the International Poultry Science Forum in Atlanta today (Jan. 29) by Arianna Ferguson, a sophomore majoring in Veterinary and Biomedical Sciences.

 

Her research focused on the performance of the "Artisan Gold," a French bird with Black Spanish heritage in a trial with 12 pens of turkeys, each holding six birds. Six pens were given commercial feed. The other six pens were fed commercial feed plus 15 percent natural feedstuffs. The feed mix was designed to encourage the birds to consume the natural feedstuffs, such as insects, mushrooms, forages, berries and nuts.

 

To determine their feed conversion, the heirloom birds were weighed weekly and their feed intake measured. Early in the study the birds consuming natural foods seemed to be eating a little more than the control group and weighed slightly more. However, by the time the turkeys were processed at the Penn State Poultry Education and Research Center in December, the birds that consumed natural feedstuffs weighed essentially the same as turkeys in the control group that ate only commercial poultry feed. Hens weighed 11.84 pounds at 16 weeks and toms weighed 19.13 pounds at 18 weeks.
