Howdy Yall,

I’ll be presenting tomorrow at the 51st Annual Independent Cattlemen’s Association Convention over the Effects of Nutrition on Reproduction. If you’ll be in the San Marcos, TX area, stop on by!
In this presentation I’ve added some really neat information on fetal development/fetal programming.
Often times I come across breeders in different species that don’t put an emphasis on the mother’s nutrition because they’re using a recip.
Just because the mother may not be as genetically superior as the baby she’s carrying, doesn’t change the fact that what her diet consists of is influencing the development of that baby in utero.
You could be holding back those genetics severely if that mom is not receiving proper nutrition in her diet.
If this subject is something of interest, let me know what species you want more info on and I’ll get the next write up on it.

God Bless and Gig ‘Em!

That Makes Sense

Howdy!
I’ve had some recent consultations that end with, “that makes sense.” One consultation in particular revolved around this hay analysis that a good friend of mine provided, see below.

As we walked through the analysis, I was making some predictions based on what the values tell us along with some experience I’ve gained along the way as a hay farmer.
We’ll focus on horses this go round. On average an 1100 lb horse is going to need 20-35 Mcals of energy based on level of activity, 21-44 grams of lysine, and 700-1000 grams of protein per day.
Now these requirements will vary on age, level of activity, and stage of production.

If our 1,100 horse is eating 2.25% body weight (27.5 lbs) of this hay per day that gives us 24.75 Mcals of energy, 63.25 grams of lysine, and 1,804 grams of protein per day.
Horses eating this amount of hay should look good because we’re meeting and or exceeding their requirements because this is some really good hay.

If they don’t, then we investigate if something is underlying we’re not aware of such as ulcers, leaky gut, teeth quality, parasites, etc. However the often overlooked part is hay fluctuates as often as you buy it.
Keep in mind, if we’re feeding 2-2.5% body weight in hay and 0.5-1% body weight in grain, where is the majority of our nutrients coming from?
If someone tells you forage is not important, I’d ask why?

If you’re buying from the same feed store, they may have different hay vendors. As a hay farmer, I can tell you hay fluctuates cutting to cutting.
The better quality hay, the less grain you feed and vice versa.

The big caveat to all of is, not all horses will eat 2-2.25% body weight in hay. Reason could be either we’re under feeding and we don’t know it or; the hay quality is too mature.

In other words, the hay takes too long to digest and takes longer to go through the digestive tract and keeps the animal “feeling full”. For someone wanting to lose weight, this would be great, not for someone who’s wanting to put on weight.

I hope this helps you understand this subject more and that it makes sense.
If it doesn’t, let me know!

God bless and Gig ‘Em!

Howdy Yall,

I’d like to share a little tip on water intake that was sparked by a little convo my wife and I were discussing after our water holding tank started to drop faster than usual.

We have a cistern style water system where we use our irrigation well to pump water into a holding tank. We’re able to monitor how much water cattle drink on a daily basis. Here recently we noticed their water intake increase with the colder weather.

Additionally, I was noticing their manure starting to stack up slightly, which indicates a slight deficiency in daily protein intake. As I increased available digestible protein, their manure started to soften back into pancake patties.

Subsequently, as feed intake increased, water intake increased as well. Generally, water intake will trend with feed intake until temperature becomes a factor.

On the flip side, if you’re noticing your animals not drinking water during colder weather, you can offer free choice salt, and or preferably a loose vitamin mineral to help increase water intake.

Additionally, water quality also affects feed I take. Always make sure to have clean fresh water, if not you may be losing performance via decreased feed intake.

Hope this helps you understand this topic a little better.

God Bless and Gig ‘Em

Howdy Yall,

This week I’d like to share a little conversation I had recently with Jose Salas, owner of Salas Performance Horses in Seguin, TX, that covers a topic many horse trainers face, horses flooding their stalls with urine.

Horses around 1100 lbs, on average, have a protein requirement around 700 grams of protein per day. When they are fed protein in high excess, their body will excrete the excess nitrogen from their body through their urine.

Fun fact, crude protein is simply a calculation based on the amount of nitrogen something contains. If you’re really looking at building muscle, look at the amino acid profile.

Nitrogen in the body is in the form of urea and when it comes in contact with oxygen, it’s converted to ammonia.

This ammonia is what we smell in the air and if your stalls are not well ventilated, it could become a problem for some horses and or cattle by causing irritation in their lungs. If you’re feeding hay on the ground, you may hear more frequent coughing during feeding time which could affect feed intake.

If you are top dressing with different supplements, you may want to check your math to ensure you’re not contributing to this underlying problem.

This is largely due because most Vitamin C, B vitamins, and minerals are water soluble, meaning the body will absorb what it can and excrete the rest in urine.

Some big concerns Jose and I discussed were how this could affect his program by increasing their horse’s water requirements, decrease stamina, increase labor for cleaning stalls, and cost of shavings etc.

Now that we’ve made some adjustments to Jose’s program, we’ll give it some time before we consider altering anything else.

Working with people like Jose and his family are why I love what I do. We’re all striving to get better in what we do and if I can help someone reach their goals, I’ve done my job well.

Hope this helps you understand a little more on this topic!

Howdy yall,

2025 Cattle Con is in the books! This year’s NCBA was in my backyard in San Antonio, TX.

We got to demo our handheld NIR machine with producers who are looking at fine tuning their program, not only for cattle, but horses too. Horses play a vital role in cattle operations and producers tend to ask additional questions regarding them while I’m on ranch calls.

One interesting conversation I had was around forage quality fluctuation in their horse’s program.

It happens a lot more than most people give it credit for.
If you’ve been buying the same grain and the same hay from the same feed store, yet you’ve been noticing a decrease in body condition, chances are that forage is the likely changing in quality.

For the most part, most feeds regardless of locked formula or least cost formulation, are going to spec out what is on the guaranteed analysis. Therefore, make sure what you’re looking for on a feed tag is actually at a guaranteed level, not just in the ingredients list.

If you’re feeding grain at 0.5% BW or 7.5lbs per day to a 1,250 lb horse, and your horse is losing weight, chances are 1.5%-2% BW or 18-25lbs of your forage may be the culprit.

The feed is formulated to fill in the gaps of “your” hay/forage program.
The next time you ask someone what grain they’re feeding their horse, also ask what type of hay/hay quality is part of their program.

If I’m building a custom horse feed, I’m building it around your forage availability and quality. This helps me account for protein, amino acids, calories, trace mineral, water quality, and NSC content.

Hope this helps give a little insight on this subject.

God bless and Gig ‘Em!

Forage importance

Howdy Yall,

This past week in my consultations I had an underlying theme across species, forage importance.
Have you ever had a situation where you were so happy with your program then all of sudden your horse starts losing weight and “you haven’t changed anything”?
These conversations come up quite often and I’d like to hit on a few points to help shed some light on this.
Most feed companies are either going to have a locked formula or least cost formula.

What is the difference between the two you may ask? Well, a locked formula is a formula that doesn’t change, I.e. the ingredients don’t change, but the price will. Whereas, a least-cost formula’s price stays consistent but the ingredients in the feed may fluctuate to account for ingredient price changes.

We won’t dive in on this topic of the pros and cons for locked and least cost formulas but keep in mind they are both keeping your guaranteed analysis/calories the same.
While this is important, most people don’t focus as much on the hay.

I’ve tested hay at feed stores, hay farmers, and customers barns, and one underlying theme across them is they can only ‘assume’ what the quality is.

An 1100 lb horse requires 800-1100 grams of protein per day depending on work load.

If your hay quality fluctuates from 8-13% crude protein from batch to batch, your horse could be seeing anywhere from 799g to 1298g of protein per day, eating 2% of their body weight per day of hay.

There are just as many other nutrients that follow that same trend including digestible energy, which is what help add that “bloom” you’re looking for. If we’re dropping several hundred calories per day, this may help explain why you may be seeing inconsistent results.

You should look at all the variables in your program and adjust accordingly. Working with a nutritionist will help you understand which levels you may be deficient in.

Hope this helps you understand this topic a little better.

If you need help in your program, don’t hesitate to reach out!

God bless and Gig ‘Em!

Howdy Yall!

I’m looking at increasing my nutrition content this year and need yalls help!! ❗️ ‼️

Feel free to respond to this comment or shoot me a personal note.

Looking for information such as specie interest (cattle, horses, sheep, goats etc), written articles, short tip reels/videos, virtual consultation Q/A, audio recordings etc. How do you like to learn? Is it in the classroom, couch, or on horseback?

During my consultations we cover so much ground and producers want to record to review content.

If you know me personally, you know I love education and helping others learn more.

This year I want to help others who want to know the whys and why nots about their animal’s nutritional needs, debunk myths, know what makes a feed good or bad, know if someone is selling fluff, and more importantly how to save money.

Let me know what yall think on how I can help!

Feel free to share!!

God bless and Gog Em!
