Supplements could help in combating livestock pasture nutrient deficiencies

Planning ahead for livestock pasture quality decline can help combat potential nutrient deficiencies

Just as quickly as fresh green pastures appear, pasture quality can diminish, leaving both pasture and cows' nutrient deficient.

These potential nutrient deficiencies come at a critical time frame when the cow likely has a calf at side, and is either on target for re-breeding or is already re-bred and trying to grow her developing calf.

"Producers may see cows slip in body condition score throughout the summer," says Dr. Kelly Sanders, cattle nutritionist for Purina Animal Nutrition. "Forages mature as the summer goes on, losing nutrients, specifically protein, and allowing cows to lose body condition."

If forages are running under 7% protein, then you likely don't have enough protein to support the cow and her calf. The majority of producers across the United States, unless they have some high-quality forages stockpiled, are not above that level and will need to find additional nutrient sources.

Sanders recommends using protein supplements to avoid this slip in condition, especially late summer and into fall when grasses are lowest in nutrient value.

"Adding protein tubs or cubes are two ways a producer can supplement their cow herd during this time of high nutrient requirement," says Sanders. "Protein tubs can be fed from mid to late summer through mid-fall, then cubes can be fed upon the first freeze or in the later fall months."

Protein supplements should be added before cattle start losing body condition. Sanders recommends evaluating your pasture at various times throughout the summer, specifically mid- to late-summer, and adding a supplement before the pasture quality is too far diminished.

If pastures are not adequately managed, protein deficiency may become a herd health challenge with symptoms including reduced intake and forage digestibility, reduced growth rate (both fetus and calf), loss of weight, inadequate intake of other nutrients, delayed estrus, irregular estrus, poor conception rate and reduced milk production.

"It all narrows down to making sure your cows have what they need, when they need it," says Sanders. "If they're not getting the complete nutrition they need when the pasture is at its worst quality, you will likely see challenges develop. These challenges may be easily avoided by implementing a protein supplement program."
