A recent Kansas State University study found that providing growing cattle with dried distillers grains (DDGS) plus salt on a self-feeding basis while the animals grazed native pastures helped boost average daily weight gain without the indirect expenses linked to daily delivery such as fuel and labor.
During the two growing seasons prior to the 2013 study, the Flint Hills area of Kansas, like much of the state, experienced drought which stressed pastures.
Looking for ways to optimize cattle performance and maintain pasture health, a team of K-State researchers conducted a study with beef heifers over a 78-day period at K-State&rsquo;s Beef Stocker Unit in the northern Flint Hills. While grazing, some of the heifers had access to DDGS mixed with salt at two different levels.
DDGS are a byproduct of ethanol production and are commonly fed to beef cattle, particularly in areas where ethanol is made. Most ethanol is derived from corn, but can also be made from other feedstocks such as sorghum or wheat.
&ldquo;We have known for several years that DDGS is a good source of protein and energy when fed as a supplement for cattle,&rdquo; said Dale Blasi, extension beef specialist with K-State Research and Extension. &ldquo;In this study we wanted to determine the consumption and resulting growth from supplemental DDGS when provided at two levels of salt addition.&rdquo;
&ldquo;Salt limits the intake of DDGS,&rdquo; said Blasi, who led the research team. &ldquo;The more salt that is included, the less DDGS is consumed.&rdquo;
The cattle were split into three grazing &ldquo;treatments,&rdquo; each consisting of four pasture paddocks. Heifers in the control paddocks (85 head total) were fed no DDGS with salt, while heifers in the &ldquo;low&rdquo; paddocks (94 head) had access to DDGS with 10 percent salt. Heifers in the &ldquo;high&rdquo; paddocks (100 head) had access to DDGS with 16 percent salt.
The cattle in the control paddocks had an average daily weight gain of 1.91 pounds over the 78-day grazing period. Those in the &ldquo;low&rdquo; paddocks that consumed DDGS with 10 percent salt had an average daily gain of 2.62 pounds and those in the &ldquo;high&rdquo; paddocks with access to DDGS with 16 percent salt gained an average 2.41 pounds.
Cattle in the &ldquo;low&rdquo; treatment paddocks consumed approximately 3 pounds per day more DDGS than their counterparts in the &ldquo;high&rdquo; group consumed.
&ldquo;This supports the idea that providing DDGS with salt in a self-fed fashion can be used to improve cattle performance without the indirect expenses associated with daily delivery, such as fuel expenses, labor, and others,&rdquo; Blasi said. &ldquo;Providing DDGS to cattle on native grass at about 0.3 percent of body weight will significantly improve performance.&rdquo;
