Hy-Plains Feedyard with Paula

Written by: Patti Dollarhide

Paula Ghazarian

“Paula, do you want to go on a road trip?”

“Sure, where to?  We made great memories when we traveled to the nutrition conference in Miami on the beach a few years back.  When and where?”

“June 20, 2019 at Hy-Plains Education & Research Center, Montezuma, KS.  Be sure to wear close-toed shoes.”

And that is all it took to get my friend Paula Ghazarian, RN, leader of the Infection Control oversight team at one of the largest hospitals in Kansas for many years, to attend the “Appropriate Antimicrobial & Use & Stewardship” conference several hundred miles away.  She is a life-long learner who pursues learning no matter what the time or setting.  Paula was raised in West Virginia and has stories about raccoons, squirrels and prized coon dogs that make you laugh so hard your stomach hurts, but we soon found that cattle chat was a foreign language to her.  The cattle talk took us to other health-related topics.  I could feel some common ground as she shared her frustration with parents who choose not to vaccinate their children, resulting in outbreaks of vaccine-preventable diseases.  This easily translates to the cattle business as our customers want us to stop using antibiotics to treat food animals.

We arrived at the Hy-Plains feedlot a little early, and Tom Jones took time to give Paula a tour of the cattle processing area.  Her morning started off with amazement.  “I had no idea it would be so calm, quiet and clean.  I was expecting chaos and very bad odor.”

Paula asked a few questions that were easy to answer, as well as some that don’t really have answers.  She was disappointed that a retailer she held in high esteem due to their stand against antibiotics in chickens has created a trade-off that includes a negative effect on animal welfare.  Increasing animal mortality is not the outcome she wants.

As the day went on, speakers discussed opportunities in our business to reduce stressors that drive how we currently use medically important antibiotics   Modern beef production is a highly specialized business in which technology has allowed farmers to produce more food for a growing world and still stay in business – a cattleman’s ultimate definition of sustainability.

Two different times during the day, questions came from the agriculture audience wondering what the human medical community is doing to address appropriate use and stewardship.   We know, and they know, that there are opportunities.  Paula shared multiple examples on our return trip of how practices and procedures have changed, such as simple oversight in the ICU to remove Foley catheters after three days which had an immediate impact on infection reduction.   She also shared case studies that her specialized infectious disease team worked with that would break your heart.

One Health recognizes that the health of people is connected to the health of animals and the environment.  Research and industry collaboration are essential.  I was proud to have my friend see and hear the efforts that are going on in the agriculture community to make change so she will trust our food supply and want to continue to eat beef

My hope for future meetings is to include more human health professionals in our discussions.  Let’s hear what initiatives they are working on and address antimicrobial use together.

Thru the eye of an infection control nurse not familiar with USA Beef production:

  1. How do the animals get out of this chute?  How do you get them back to the pen?
  2. Why do you track “days on feet”?  Aren’t they always on their feet? 
  3. What are “check off dollars”?
  4. I have never heard of ionophores in human medicine.  What are they? 
  5. There is a lot to know about.
  6. How to the producers at the farmer’s market fit into this model?
  7. There are trade-offs. 
  8. I never thought about how we grind different animals together to make hamburgers.
  9. Antibiotic resistance is everyone’s problem.  We have a lot of examples of changes we have made in human medicine, as well as a lot of challenges this group might be interested in.

Using the Pregnancy Analytics Mobile App: Bull problems and BSEs

The Beef Cattle Institute’s Dr. Bob Larson brings you a series of “cases” employing the use of the Pregnancy Analytics mobile app. Each case will explore a unique herd and examine its reproductive efficiency, strengths, challenges and areas of improvement. The reports (linked below) will lead you through using the Pregnancy Analytics app to utilize the data and practice using it on an actual problem herd.

The case: Bull problems and BSEs

A herd of 209 commercial red-composite cows was palpated on October 7. The herd is split into three breeding pastures with bulls being turned out on June 10 and removed on August 15. The calves were being weaned on the ranch (i.e. left in their current pastures) and the cows were being trucked to a new pasture so the owner started dropping off cows at your clinic very early in the morning to be preg-checked, dewormed, and vaccinated before being taken to fall grazing on corn stalks. During the breeding season: 62 were in the “West Pasture” with two bulls, 81 were in the “North Pasture” with three bulls, and 66 were in the “Windmill Pasture” with two bulls. About 60% of the first-calf heifers were in the West Pasture –– with the rest split between the other two pastures.

Findings

Seventy-six cows were open (64% were pregnant) and only 8% of the cows were classified as being “thin” (BCS <5).

The first analysis of the preg-check data was to look at the percent of the herd that became pregnant each 21-day period of the breeding season and we find that 44.5% of the herd became pregnant in the first 21-days (pregnancies would have been 98 to 119 days), 13.9% in the second 21-day period (77-97 days), and 5.3% in the third 21-day period (56-76 days). The goal for this herd (and most herds) is to have at least 60% of the cows becoming pregnant in the first 21 days of breeding.

Another way to evaluate preg-check data is to determine the percent of the available (non-pregnant) cattle that become pregnant each 21-day period. Recognize that as the breeding season goes along, once cattle become pregnant, they are no longer available to get pregnant again, so the percent of the herd that becomes pregnant each 21 days is not the same as the percent of available cattle that become pregnant each 21 days. To display this measure of reproductive success using the Pregnancy Analytics App – select “% Preg Success”. Based on expected pregnancy success when both cow and bull fertility is optimum, the “% Preg Success” goal should be between 60%-70% for every 21-day period of the breeding season.

Looking at the percentage of open cows that became pregnant each 21-day period, we find that either cow or bull fertility (or both) was lower than desired at the start of the breeding season (44.5% settling in first 21 days) and pregnancy success did not improve and in fact got worse as the breeding season progressed (25% in the second 21 days and 12.6% in the third 21 days).

In this herd, the poor over-all percentage pregnant clearly indicates a problem and the percent pregnant by 21-day interval provides information that the poor reproductive performance continued for the entire breeding season. To begin to evaluate the herd further, the Pregnancy Analytics App provides a way to easily divide the herd into pertinent sub-groups – and when the pregnancy success by 21-days is evaluated by age group, we find that both the first-calf heifers and the mature cows had too many open cows. (1st-calf heifers are defined as those cows suckling their first calf and being bred for their second pregnancy).

More information can be found by displaying the % Preg Success and while neither the 1st-calf heifers nor the cows reached the expected reproductive performance of 60-70% of open cows becoming pregnant in a 21-day period –– the 1st calf heifers tended to perform better than cows and the performance declined over the breeding season.

The preg-check data can also be evaluated by comparing the breed-up differences between body condition score categories. We know that only 8% of the herd was classified as “thin” at the time of preg-check, so we may be justified to ignore any assessment of the association between BCS and pregnancy distribution in this herd; but to be complete, I looked at BCS and found that cows classified as being in moderate body condition performed as poorly as cows classified as being thin.

So far, the information I have looked at raises the possibility of either Trichomoniasis or bull problems being the most likely rule-outs – with cow infertility due to nutritional or late-calving being less likely because the magnitude of open cows is more compatible with bull problems or Trich and the fact that fertility does not improve as the cows have more time post-partum to resume fertile cycles as the breeding season progresses.

The most revealing information about this herd is obtained by looking at the effect of breeding pasture on reproductive performance (both the pregnancy distribution and % Preg Success).

I interpret this information as evidence that the primary problem for this herd is in the Windmill pasture. The other two pastures (West and North) perform very well early in the breeding season – indicating that the cows must have had time post-partum and adequate nutrition pre- and post-partum to resume fertile cycles by the 21st day of the breeding season. Nearly all the open cows were in the Windmill pasture and fertility was very poor throughout the breeding season. The magnitude of the infertility is worse than I would expect for Trichomoniasis and definitely worse than I would expect with a cow problem (in addition, excellent cow performance in the other pastures pretty much rules out a cow problem). The poor reproductive performance in the Windmill pasture must be due to a bull problem.

Conclusion

The primary problem in this herd is in the Windmill pasture and almost has to be due to a bull problem even though the rancher reports that all the bulls were between three and five years of age and had been successful breeders in previous years. I would recommend a BSE on both bulls from this pasture, but if one or both bulls pass the BSE, my diagnosis would not change (finding a musculoskeletal or semen problem in one or both bulls would confirm the diagnosis).

To prevent this problem in the future, I would strongly recommend a BSE for all bulls before the start of breeding and frequent assessment of bull musculoskeletal health and amount of estrus activity throughout the breeding season.
