New findings on reproduction
in high producing herds
There is a strong negative relationship between the level of milk production and the duration of estrus. If a cow is producing 70 lbs. of milk per day, a four time a day heat detection program will detect about 90 percent of the cows in estrus. The same program won’t work nearly as well when cows are producing 100 lbs. per day. What should you do? Click here to learn about reasonable reproductive management practices that offer practical results to address this issue, as well as many others that were reported on at the Western Dairy Management Conference.
A new way to measure sire fertility
The A.I. industry recognizes multiple systems for measuring sire fertility. Which system should you trust? Click here to learn about the Select Sires’ Composite Fertility Index (CFI), which includes data from all available U.S. sources including Relative Breeding Efficiency, ERCR and Agri-Tech Analytics data.
Milk pregnancy test among current research
Ongoing research is key to developing new opportunities. Click here to read about AntelBio’s current research efforts on pregnancy detection, as well as their ongoing work on Johne’s disease.
A look at health and fitness traits
What does it really mean when a bull is +3.2 for Daughter Pregnancy Rate (DPR) or +6.0 Productive Life (PL)? Click here to learn more about DPR and PL, including their use as a selection trait, heritability and ultimately what the real benefit is to you.
Why did that bull’s proof change?
Improvements were made in the production and type evaluations with the May Sire Summaries. The new methods include more data and results in evaluations that are more stable and consistent with genetic evaluations in other countries. Click here to learn about the changes and how it affected various traits.
PCDART update offers ultimate “to-do” list
