Testing Tells Alfalfa's Worth

"Cows and horses think alfalfa looks like candy, smells like candy and tastes like candy," says University of Missouri Extension livestock specialist Andrew McCorkill.
 
However, alfalfa's proof is in the pudding. Not all hay that looks good is good hay. Not all good hay looks good. The only way to know is by testing samples to determine the nutritional value.
 
McCorkill spoke at a recent MU Extension alfalfa tour. MU Extension in Greene County and Mid-Missouri Bank sponsored the tour at the Rick and Justin Williams farm in Ash Grove.
 
Testing gives nutrient information needed to make supplement decisions. Hay testing is one of the cheapest and best investments a livestock producer can make, McCorkill says.
 
"Sometimes our forages are better than we think, but a lot of times they aren't," he says. Hay's value cannot be measured simply by eye appeal. It is a case of "Pretty is as pretty does."
 
Protein, energy and fiber content determine how our livestock perform, McCorkill says. Hay with high nutritional value helps dairy cows make more milk. Dairy producers can feed less grain to cows when hay has high nutritional value. Horse owners may choose alfalfa for its soft, leafy green stems favored by horses.
 
Alfalfa works as a good supplement for beef cows on mostly poor-quality fescue hay. Some producers use it as a creep feed for calves as well. "Alfalfa has an intrinsic value that is not explained by numbers alone. Livestock just perform on it if it's fed properly," he says.
 
"Less mature cuttings tend to be more digestible," McCorkill says. Livestock favor the early tender cuttings over later-season stems that are more brittle, tougher and contain more indigestible fiber.

Video: Season 5, Episode 11: New Split Suckling Research Reveals Surprises

A recent research collaboration between a university and a commercial farm studied 1,500 sows and 22,000 piglets and discovered unexpected findings about the common practice of split suckling. Their research found that this long-standing practice might not be benefiting piglets on day one as much as producers previously thought.

Discussing the research are Mikayla Spinler, a graduate research assistant at Kansas State University, and Ashley Hartman, a research coordinator at Pillen Family Farms and DNA Genetics. The two discuss how the research was chosen, conducted and next steps on today’s episode.
