Free access to minerals is crucial in all stages of life for your cows. However, there are periods where extra supplementation is needed to ward off disease, increase productivity, and set your animals up for a healthier future. Let’s take a more in depth look at the dry period, what your herd needs, and why.
Giving your cows a healthy dry period before calving and lactating directly impacts:
For years, agricultural scientists have supported the idea that lifelong performance can be pre-programmed into cattle before calving. This “fetal programming”, which in part involves extra mineral supplementation, is one way to not only reinforce the health of the cow, but also your herd’s next generation.
For example, in a recent study, beef specialist Reinaldo Cooke (Oregon State University) discovered that extra mineral supplementation during the dry period significantly improved calf gains:
“Just putting simple math to it, we gained up to $70 in calf value with an investment of $2 or $3 per cow”
Investing during the dry period can yield significant gains during calving and lactation.
“As much as 50% of the absorptive area in the rumen may be lost during the first 7 weeks of the dry period” (National Research Council)
It's no wonder dry cows need extra minerals!
Mineral supplementation during the dry period develops a more robust immune response and supports a healthy metabolism. Let’s look at some of the health concerns of dry cows and how minerals can help. *Note: many of these disorders can be interrelated and targeting metabolic health in general can help across the board.
Ketosis is a metabolic disorder that usually occurs within 2 weeks after calving. After giving birth, milk production and physical recovery consumes a lot of energy which can cause a negative energy balance. As body fat is metabolized, non-esterified fatty acids (NEFAs) build up in the blood and overwhelm the liver. Mineral supplementation during the dry period can correct metabolic imbalance and prepare your cows for the added strain of calving and lactating.
Retained placenta (aka retained fetal membrane or retained cleansing) happens when the placenta fails to separate from the mother within 24 hours of birth. RP not only exposes your cow to serious infections, but it can also delay their next pregnancy by several months. Dry cow management is the best way to prevent RP from occurring.
According to UC Davis Veterinary Program, one of the most obvious ways of preventing RP is:
“make sure your trace mineral and vitamin supplementation program is adequate” and points specifically to selenium, iodine, vitamin E and A.
According to University of Minnesota:
“Milk fever, or hypocalcemia, has been a problem of fresh cows for over two centuries. Effective nutritional management during the dry period and early lactation has decreased clinical cases of milk fever to rates lower than 1 percent.”
When blood calcium levels are too low, your cow’s body begins “mobilizing” calcium stored in their bones. For short periods of time, this natural mobilization is not a concern but can be detrimental over time. However, it is best to avoid heavy supplementation of calcium because your animals can become over-reliant on supplements, excess calcium is wastefully excreted, and can have harmful effects within the body. Metabolic stability can be achieved when animals have access to a balanced profile of electrolytes, other macrominerals, and trace minerals. Just look at how Redmond’s balanced mineral mixes can stabilize your cow’s liver mineral concentrations!
The mineral levels of your soil and forage vary quite a bit from year to year and acre to acre. Testing your soil and forage is the best way to know what your specific deficiencies are and what supplementation you will need. For example, most North American soils are naturally deficient in selenium and grazers will need extra supplementation.
