Research Finds Pigs Tolerate Higher Levels of Sulfur

OMAHA (DTN) -- Swine producers don't need to worry as much about sulfur concentrations from distillers grains in feed rations, according to research done at the University of Illinois.

According to Hans H. Stein, professor of animal science at the University of Illinois, Urbana-Champaign, pigs are able to tolerate higher levels of sulfur than previously thought.

In the past, swine producers were cautious about feeding dried distillers grains with solubles, because of their tendency to be high in sulfur. Although there were recommendations for cattle stating that no more than 0.4% of the dry matter in the diet should be sulfur, there was no data published on tolerance of sulfur in pigs.

Further research showed that swine producers could get close to 0.4% in diets, which lead researchers to wonder if pigs were as sensitive to sulfur as cattle.

"We conducted several experiments and were concerned about two things: if pigs could tolerate sulfur and if they would eat it," Stein said. "We wondered if maybe high sulfur would reduce the palatability so the pigs would not eat as much."

Researchers conducted palatability studies and growth experiments with both weaning pigs and growing pigs. In the end, there was no difference found in the palatability and growth performance between feeding a diet containing very low sulfur and one with very high sulfur.

Researchers also wondered what happens to the sulfur the pig is consuming and whether the sulfur would show up in the animal's tissue and meat sold to consumers.

Previous studies had determined that pigs can consume diets containing up to 0.38% sulfur without affecting palatability or growth performance. So a feeding trial was formulated using two diets: one with DDGS containing 0.3% sulfur and a second diet with calcium sulfate added to simulate a high-sulfur DDGS at 0.9%. The sulfur content in the total ration for both diets was at 0.14% and 0.38%, respectively -- lower because the DDGS was mixed with other feedstuffs.

The researchers found carcass length, 10th-rib fat depth, loin area and fat-free lean were the same regardless of the diets pigs were fed. Also, the sulfur content did not have any effect on organ weights, loin quality, loin pH, drip loss, loin subjective color, marbling or firmness.

The most important discovery came was when tissue samples from the pigs fed high sulfur diets showed the animals were able to regulate sulfur in their bodies by increasing or reducing urinary excretion in response to the change in sulfur intake.

"Pigs will absorb the extra sulfur, but then they will excrete it in the urine afterwards," Stein said. "So you don't get pork chops or bacon with high sulfur concentrations, or anything like that."

Stein stressed producers need to keep in mind that pigs can get sulfur from other sources besides feed; it is sometimes found in groundwater in certain areas.

"Obviously, if you have high sulfur in the water and then you have high sulfur in the DDGS, then you can compound," he said. "But based on our research at least, I would say that within reasonable limits, pigs tolerate sulfur very well. Pigs are probably easier to work with than cattle in that regard."

Stein said there were some notable differences in levels of sulfur in DDGS from various sources and producers should be aware of the sulfur content in the DDGS they purchase.

"There are some sources of DDGS that are very low in sulfur, but there are also sources that are very high," he said. "Typical values range from 0.3% up to about 1% or a little higher in DDGS."

The research tested up to 0.38% sulfur in the final diet, but Stein pointed out that is probably about as high as producers would get in the diets when feeding DDGS with higher sulfur levels.

"Now, if you combine that with high sulfur water, we don't know what happens because we didn't test that," he said. "If you get into sulfur problems, I don't think it will be because of DDGS. It will be because of either other ingredients that are high in sulfur, or because of water that is high in sulfur."

Whether or not producers choose DDGS will still likely be determined by economics, Stein said, adding that the research demonstrated that producers do not need to be concerned about the 0.3% to 0.9% sulfur in DDGS. Those levels really have no impact on pig performance, carcass quality or product quality, he said.

The project, "Effects of dietary sulfur and distillers dried grains with solubles on carcass characteristics, loin quality and tissue concentrations of sulfur, selenium and copper in growing -- finishing pigs," was published in the Journal of Animal Science.

Other researchers on the project were: Beob Gyun Kim of Konkuk University in Seoul, South Korea; Dong Yong Kil of Chung-Ang University in Anseong, South Korea; Donald Mahan of The Ohio State University; and Gretchen Hill of Michigan State University.

The National Pork Board and the Nutritional Efficiency Consortium both provided funding for the project.

Alliance Develops Sample Food Safety Plan, Curriculum

A group of ethanol industry experts are working on a sample food safety plan and educational curriculum for ethanol plants to use to comply with regulations set in the final rule of the new Food Safety Modernization Act, which was released in September, according to an article by Ethanol Producer (http://bit.ly/…).

The U.S. Food and Drug Administration calls FSMA "the most sweeping reform of food safety laws in more than 70 years." A group of 10 industry exports has been working to understand the details of the FSMA final rule, as well as the requirements for every facility to adopt current good manufacturing practices (CGMPs) and extensive recordkeeping. According to the Ethanol Producer, the group worked to "pin down just what producers will need to do to ... (ensure) distillers grains and corn oil bound for feed are in compliance."

Since defining CGMPs and identifying hazards that need controls will be an enormous task, the ethanol working group, a subgroup of the Food Safety Preventive Controls Alliance, is writing a sample food safety plan for the ethanol industry. The safety plan will be used as an example in training sessions to show what a plant's CGMPs, hazard analysis and preventive controls might look like.

David Fairfield, vice president of the National Grain and Feed Association, said the safety plan is just an example, adding that FDA expects "each facility to develop a plan that is unique to its own operation."

Once completed, the goal of the alliance is to have the curriculum in place by May. All the materials will be available at no cost on the alliance website.

Other committees are developing hazard guidance and curriculum, including a 20-hour animal food curriculum. Courses will be scheduled once the curriculum is finished and approved by FDA.
