Should you delay oral calcium bolus supplementation for fresh cows?

“Subclinical hypocalcemia (SCH) is an invisible threat to both the dairy cow and producer. As nearly 45 percent of multiparous cows experience SCH during the early lactation period, producers can implement dietary strategies such as feeding negative dietary cation-anion difference (DCAD) rations in the late dry period or administering prophylactic calcium treatments to fresh cows to minimize the risk of SCH.”

“The results of our study support previous reports suggesting that oral calcium supplementation benefits a subgroup of cows. Taking this into consideration, administering calcium boluses to high-producing, lame, or older cows may be financially advantageous for producers as blanket treating every cow is costly and the financial gains from improved milk production are only realized in select groups.”

Methionine and omega-3 fatty acid feeding for transition cows.

“Our study shows that feeding transition cows a diet adequate in Met and with calcium salts enriched in n3 FAs can enhance lactation performance by increasing energy-corrected milk yield over the first four weeks of lactation and improve liver function by altering liver methyl donor metabolism.”

Reduced Lignin Alfalfa can Improve Digestibility

Alfalfa is known for its high nutritional value, and that makes it a valued forage source. However, alfalfa is often hindered nutritionally because of the indigestible lignin components in the cell wall. Using technology to improve fiber digestibility in alfalfa can provide opportunities to improve feeding flexibility and enhance animal performance. Importantly, high-quality alfalfa can be used to improve cow efficiency, production, and enhance an operation’s economic value.

Alfalfa has a number of beneficial nutritional characteristics that make it a high-quality feedstuff for dairy cows. Alfalfa is sometimes overlooked or left out of the diet because of its high expense relative to other forages. This includes its high establishment and harvest costs. This situation has led to less overall alfalfa production in the United States in the last 20 years. Incomplete fiber digestion reduces animal performance by limiting intake, and that also cascades to more manure production. When that takes place, a dairy farm’s profit potential also drops.

Clean Feed is Key to Dairy Nutrition

Feed hygiene is key in minimizing or removing the anti-nutritional factors in feed that can negatively affect animal health and performance.

Key factors in reducing feed contamination include:

  • utilizing loader buckets dedicated to feed only
  • placing silage bags on surfaces to minimize soil contamination
  • properly face silage piles and bunks
  • reduce water runoff through silage piles
  • proper height of disc mowers
  • remove rodents and birds in feed storage and feed alleys
  • tarp hay
  • maintain clean feed alleys

Considerations for Breeding Dairy Cattle to Beef Breeds for Meat Production

Producing beef x dairy cross calves has the potential to increase the market value of these calves compared to straight bred dairy bull calves. However, as the supply of beef x dairy cross calves increases, it’s reasonable to assume buyers will become more discerning. Dairy producers can stack the odds in their favor with a thoughtful beef sire selection.

In Considerations for Breeding Dairy Cattle to Beef Breeds for Meat Production, we discuss the strengths and weaknesses of Holstein steers, introduce dairy producers to EPD’s (beef genetic proofs), and provide suggestions for beef sire traits to consider when applied to dairy cattle.

By choosing beef sires that improve upon the weaknesses of dairy steers, using beef on dairy can improve feed efficiency, rate of gain and reduce days on feed. Wisely incorporating beef genetics can also improve carcass characteristics over straight bred dairy by increasing ribeye size and changing the ribeye shape, increasing muscling, and moderating frame size while maintaining the marbling ability of dairy animals.

The Role of Energy and Omega 3’s in Embryo Development

As dairy cows produce higher and higher volumes of milk, the need for a higher caloric intake is necessary to help support this huge demand for energy. Dairy cow diets typically contain some form of fat, either from rumen-active sources such as cottonseed, distillers, tallow and roasted beans or from rumen-inert fats such as calcium salts or prilled fats.

  • Palmitic, stearic and oleic are fatty acids we need to support energy in the dairy cow.
  • Cows that transition well do not experience extreme inflammation, thus they will maintain or increase DMI and avoid metabolic issues or milk loss.
  • Minimizing body condition loss and corresponding NEFA levels during the transition period will no doubt help set your cows up to become pregnant faster.
  • Providing base levels of EPA/DHA omega-3s in dairy cow diets will assist in proper oocyte and embryo development and will improve embryo implantation rate and lower pregnancy losses.

These 7 Transition Cow Diseases are Costing You Money 

When you think about the animals who are costing your operation the most money, transition animals usually sort their way to the top. Generally, most production problems can be traced back to the dry or transition period, one of the critical time frames in a cow’s production cycle.

According to Michal Lunak, Extension Educator for Pennsylvania State University, the most common management diseases that occur during the cow’s transition period on U.S. dairies are lameness, mastitis, retained placenta, metritis, ketosis, hypocalcemia (milk fever), and left-displaced abomasum. Here’s a breakdown of just how much these seven diseases could be costing you.

Making the most of manure

Manure is not a liability; it’s an asset. As livestock and cash grain margins narrow for the foreseeable future, producers should start viewing manure with the rose-colored glasses it deserves.

“To best do this, producers should track exactly how much of this valuable asset is supplied to the crop to account for its tremendous value,” explains Scott Fleming, Rock River Laboratory nutrient management specialist. Fleming adds that livestock owners should pay attention to three key factors that can affect the value gleaned from their manure: application rate, analysis, and placement.

Trickle effects of high dairy feed costs

The feed costs for dry cows and heifers can affect cash flow as much as the lactating cow. And this is especially true if forage inventories are lacking.

Feed costs per non-lactating animal can be very close to what the market is reflecting. This is due, in part, to feeding both purchased forage and grain. Examining feeding strategies for all animal groups is warranted considering the continued high feed costs this year.

Evaluating wet feedstuffs for dairy cows

Wet feedstuffs derived from the food and ethanol industries are valuable additions to cattle diets, when available within a reasonable distance from the farm. They not only provide required nutrients, but their moisture content helps condition total mixed rations (TMRs), increases their palatability and reduces feed sorting by livestock. Depending on their water content and price, however, their purchase can turn into a questionable economic decision.

Where your farm is in the U.S. determines which wet feeds are readily available close enough to justify their hauling to the farm. This article addresses the wet form of beet pulp, brewers grains, distillers grains, gluten feed, and grape pomace (also known as grape marc). We will discuss their composition and what factors to consider when evaluating their incorporation into dairy cattle diets.
