How to make your next preg check your best one yet

There are so many factors that affect how efficiently you can get cows pregnant. Cow comfort. Cow cooling. Nutrition. Herd health. Genetics. Dry cow, transition and fresh cow management. And the list goes on.

The whole picture can be overwhelming. So to help break it down, we turn to the simple lactation cycle of an Alta 4-EVENT COW. You can make your next preg check the best one yet by focusing on the management practices around the BRED and PREG events of a cow’s lactation.

Here, we share three things you can do today to improve the current reproductive efficiency in your herd – and create more of those profitable Alta 4-EVENT COWS.

1. USE HIGH FERTILITY CONCEPT PLUS SIRES

With countless sire options available, it’s often hard to choose the right bulls for your herd. If part of your goal is to make your next preg check your best one yet, one of the fastest, simplest ways to do that in this moment, is to emphasize sire fertility within your customized genetic plan.

When you use a high fertility sire, you’re upping your odds of creating a pregnancy on the very inseminations where you use that sire. That means more cows that require just one time BRED before they’re confirmed PREGnant.

The trio of high fertility Alta CONCEPT PLUS semen options will improve the fertility in your herd, regardless of which semen type you use.

  • CONCEPT PLUS DxD – High fertility sires will give you a 2%-5% greater chance at creating a pregnancy with conventional semen.
  • 511 CONCEPT PLUS – High fertility SexedULTRA sires offer a 4%-9% conception rate advantage over the average sexed bull.
  • CONCEPT PLUS BxD – High fertility beef x dairy sires give you a 2%-5% greater chance at creating a conventional pregnancy with the beef semen you use in your dairy herd.

2. PRACTICE STRICT COMPLIANCE AND ACCURACY

Regardless of your repro strategy, your cows will not get pregnant if you don’t comply with the timed AI protocols and/or maintain an exceptional level of accuracy with heat detection.

When you use timed AI…

With synchronization programs, we can never emphasize enough that compliance is king. To put that in simple, relatable terms, that means combining four things:

  • The right injection
  • The right dose
  • The right cow
  • The right time

If you miss just one of these four critical factors, any chance at creating a pregnancy based off a synchronization schedule is severely diminished, or even gone.

When you heat detect…

The fastest diagnosis that you have on your farm for an open diagnosis is timely, accurate heat detection. What we mean by this, is that if you wait until your actual preg check day to determine the pregnancy status of every cow bred 28-35 days prior, you’ll be checking some cows that may already have showed heat since they were bred.

Regardless if you use an activity monitor system or tail painting, if you’re able to detect heats with accuracy, you’ll give yourself a chance to catch those cows that come into heat. That means fewer open cows on preg check day.

3. MAINTAIN ACCURATE RECORDS

Using a software program to maintain your records gives you the best chance of sticking to point number two above. When using a timed AI program, you can set up your synchronization schedule in your her management software program so you can follow it to a T.

When it comes to heat detection, having accurate data on freshenings, last service date, and more, will ensure you present the right cows on preg check day and keep your repro program on track.

Of course, other management factors will affect how many cows are confirmed pregnant on your next herd check. But if you do your own, personal check on the three points above, you may find that your next preg check is your best one yet.

A genetic approach to improved fertility

Alta 4-EVENT COWS don’t happen by accident. It takes a clear focus on the best day-to-day management, and a long-term plan toward breeding and developing a healthy, fertile, and productive herd.

Here, we focus in on how the decisions you make on breeding and genetics can help you create more 4-EVENT COWS in your herd. We share two ways – plus some proof – that genetics are a key piece of the puzzle in main­taining a trouble-free, profitable herd – now and down the road.

1. CREATE MORE PREGNANCIES NOW

If you’re looking for a fertility advantage on inseminations today, sire fertility rankings are where you’ll want to focus. The Alta CONCEPT PLUS sire fertility evaluation ranks each sire on his ability to get cows pregnant. In fact, regardless which semen type you use in your breeding strategy, you’ll find high fertility CONCEPT PLUS options to fit.

Why should you trust Alta’s CONCEPT PLUS ratings? They are based on real pregnancy check results from progressive dairy herds throughout North America. The evaluation also maintains accuracy by accounting for factors like number of times bred, month/season, technician and breeding code effects.

 

  • CONCEPT PLUS DxD – high fertility sires will give you a 2%-5% greater chance at creating a pregnancy with conventional semen.
  • 511 CONCEPT PLUS – high fertility SexedULTRA sires offer a 4%-9% conception rate advantage over the average sexed bull
  • CONCEPT PLUS BxD – high fertility beef x dairy sires give you a 2%-5% greater chance at creating a conventional pregnancy than the average beef bull used on dairy cows.

If you’re more familiar with sire conception rate (SCR), keep in mind that Alta’s CONCEPT PLUS evaluation is more complete, current, and consistent – and actually served as a basis for SCR. The table below compares what’s included and accounted for in each evaluation.

2. CREATE MORE FERTILE COWS FOR THE FUTURE

While sire fertility selection can get you more pregnancies, and more Alta 4-EVENT COWS now, it takes a long-term plan and genetic selection for female fertility to ensure your herd’s reproduction continues to improve.

Daughter pregnancy rate (DPR), heifer conception rate (HCR) and cow conception rate (CCR) all provide a genetic basis for creating more fertile females. Emphasizing one, or any combination, of these traits in your customized genetic plan means you are breeding a next generation of cows with a greater ability to conceive.

Daughter pregnancy rate is defined as the number of non-pregnant cows that become pregnant within each 21-day period. When a sire has a DPR of 1.0, it means that his daughters are 1% more likely than the average herdmate to become pregnant in a given 21-day window. And each added point of DPR equates to 4 fewer days open.

When referring to HCR and CCR, these traits are defined respectively as a virgin heifer or lactating cow’s ability to conceive. For each of these traits, when a sire has a value of 1.0, it means that his daughters are 1% more likely to conceive than daughters of a sire with an HCR or CCR of 0.0. While DPR is a slightly different calculation than HCR or CCR, all three are a way to measure the fertility of the female herself.

It’s clear to see that the high DPR sires, do indeed, create daughters that become pregnant more quickly than the daughters of low DPR sires.

Top 25% for highest Sire DPR1742.327%
Bottom 25% for lowest Sire DPR137-1.120%
Difference3.47%

IMPROVE FERTILITY RESULTS – NOW AND INTO THE FUTURE

If your goal is to create more Alta 4-EVENT COWS through improved fertility and reproduction, don’t miss out on the impact that genetics can make in taking you to that next level. Despite the low heritability of fertility traits like DPR, these two tips will help improve your herd’s reproductive results now and into the future:

  1. Improve conception rates now by using sires with the high fertility CONCEPT PLUS rating to boost your herd’s current conception rates.
  2. Improve fertility for the future of your herd by including DPR and/or HCR and CCR in your customized genetic plan to create a next generation of more fertile females.

Introducing the All-New Alta 511 CONCEPT PLUS

If you’ve used sexed semen on your dairy, you already know that sexed semen fertility is not the same as conventional semen fertility. It’s no secret that individual bulls may perform differently as conventional semen than they do as sexed semen.

Millions of pregnancy check records in the CONCEPT PLUS database confirm these differences in sire fertility between conventional and sexed semen.

Based on research from our product development team, you now have access to the all-new 511 CONCEPT PLUS ratings! This designation tells you which sires give you the best chance at creating pregnancies with Alta511 SexedULTRA sires.

On an individual bull page, look for the purple 511 CONCEPT PLUS logo to know which bulls offer the best chance at creating a female pregnancy.

CONCEPT PLUS sires still tell us which bulls provide the highest conception rates using conventional semen. The new development around sexed semen fertility just gives you a more precise way to know which bulls best fit your genetic plan and strategy.

We trust the data behind CONCEPT PLUS more than any other sire fertility evaluation because:

  • IT’S COMPLETE
    • CONCEPT PLUS accounts for the effect a technician or breeding code can play on a sire’s fertility within a given herd.
    • Data is collected from US and Canadian herds, and not limited to US herds on official test.
  • IT’S CURRENT
    • We collect current pregnancy check results through DairyComp from our partner herds and include only information from the past two years to designate CONCEPT PLUS sires.
  • IT’S CONSISTENT
    • Data is only gathered from progressive, large-herd environments, where management is consistent, contemporary group sizes are large, and repro programs are aggressive.
