- About Alta
Genomic proofs have provided the confidence to use exciting sires earlier in their careers. This offers you the gift of faster genetic gains leading to greater profitability.
Within the new list of daughter-proven graduates you’ll find the #2 udder bull and #1 PL sire among all daughter-proven sires in the industry!
The newest additions to Alta’s daughter-proven line-up are also graduates of the FutureStar program. This means that many people reading this may have used these globally popular sires because of their elite genomic levels, paired with early daughter information proving low calving ease and high sire fertility.
With December proofs, we’ll be unveiling the brand new Alta Jersey program.> Read more
Assessing appropriate iron levels in drinking water for cows
When given access to drinking water, lactating dairy cows can handle iron (Fe) concentrations of up to 4 parts per million (ppm) without decreasing the amount of water they consume, according to results of a recent study entitled, “Preference and drinking behavior of lactating dairy cows offered water with different concentrations, valences and sources of iron.”
Breeding & Genetics
There are several ways to get heifers bred quickly after they move into the breeding pen.
Ultrasound use has been a popular diagnostic tool for detecting early pregnancies, but the true benefit to reproduction comes from identifying open cows even sooner. A skilled ultrasonographer can identify a fetus and a heartbeat within 26 days of gestation.
Suboptimal reproductive performance leads to extended days open, increased culling due to reproductive failure, and decreased milk yield.
What are some of the risk factors for postpartum cows to be anovular (non-cycling) for a prolonged length of time? Researchers at the University of Guelph set out to find some answers using data from 2,178 Holstein cows in six commercial herds.
?The recent hot and dry spell is putting pressure on dairy cows and
grass growth as many herds are starting to see yields affected.

Feed & Nutrition
Over the last few decades, ration balancing tools and product development technologies have improved exponentially. We also have a greater understanding of the cow's biology and dietary needs.
This understanding has led to simple, yet highly effective, nutritional products that enhance animal performance – rumen buffers, protected fats and yeast derivatives – merely being added on top of the existing diet.
These products are known as "feed additives." But what about more complex product technologies such as rumen-protected amino acids?
A New York state dairy noticed that its heifers were falling short of the herd's growth goals. The farm owner called in the herd's nutritionist to see how they could get things back on track to ensure heifers entered the lactating herd in a timely fashion.
Why is this an issue? Every month that calving is delayed beyond the 22-month target costs the dairy about $100 per animal because of lost production and fewer days of productive life.
New research shows that when calves on a higher plane of nutrition were fed three times a day instead of two, they had a much better chance of entering lactation than calves fed twice a day.
Management & Economics
WHILE farmgate milk prices increased by an average 5 per cent during the 2010/11 milk year, the commodity markets indicator, AMPE, showed a 31 per cent rise.
