Justin A Ramirez, M.S. - Livestock Nutritionist Howdy! I am a livestock nutritionist with experience and graduate education in various species. Thank you for visiting my page!

I’m a livestock nutritionist and work as a nutrition consultant for various species. I earned my Masters of Science in Ruminant Nutrition from Texas A&M University in 2014 and my Bachelor of Science in Animal Science from Texas A&M University-Kingsville in 2010. In addition, while working on my masters, I taught the Feeds and Feeding lab for 2 years. I still have educational material used in lab and research based articles that I use for support. My thesis was over identifying feed efficient cattle through RFI, residual feed intake, on Santa Gertrudis cattle from the King Ranch. I grew up on a beef cattle and horse ranch in south Texas and my family has run Charolais and black Brangus cattle for 50+ years. My certifications include: Artificial Insemination for beef cattle and Certified Veterinary Assistant. If you have any questions, comments, or concerns, please feel free to contact me with all of your livestock nutrition needs.

I had a great time recently working with Prairie View A&M Extension and Texas A&M AgriLife Extension at a producer workshop hosted by the East Foundation in Hebbronville, TX.

We spent time discussing how to better manage feeding programs during drought, along with some hands-on work palpating bred females at different stages of pregnancy demonstrated by Garrett Stribling of the East Foundation.

One of the biggest takeaways—knowing pregnancy status earlier gives you more control. It helps you make smarter decisions when it comes to culling, feeding, and managing your herd through tough conditions.

I’m grateful for opportunities like this to work with producers and be part of improving real-world operations.
Thank you Romeo Ozuna for the opportunity to support extension and the whole crew at the East Foundation for hosting this great workshop.

If you’ve got questions about your current feeding program or herd performance, feel free to reach out.

Howdy!
I’m excited to be part of this great workshop in south Texas for beef producers focusing on practical information you can plug right away in your program.
Space is very limited so please reach out to Romeo Ozuna to get your space reserved.

I’ll be focusing on managing your cattle appropriately for their nutritional needs based on pasture conditions, hay quality, and their age/stage of production.
When you understand your cattle’s needs, you can provide them a diet that avoids issues down the road.
I’m excited to get back down to south Texas! Holler if you have any questions.

Part 1: Unpopular opinion feeding grass hay vs. alfalfa hay and why this is a hot topic with equine owners. This same logic applies to cattle producers as well. Sorry I got cut off at the end. Stay tuned for part 2 tomorrow.

Research suggests developing females to 60-70% of their mature weight by breeding season.
Subtract your target weight by your current weight and divide by the number of days it’ll take to get to breeding time.
Testing your hay lets you know how much more you have to feed to achieve targeted rate of gain.
My personal recommendation is 1.6-1.8 lbs ADG to avoid over conditioning which can result in lower milking capabilities.
Knowing your numbers helps keep your program efficient and avoid problems down the road like lighter weaning weights and dystocia.
Holler if you need some fine tuning in your program.

Howdy Yall,

If you’re a beef cow-calf producer in the Seguin and surrounding areas, stop on by tomorrow evening learn more on building winter programs around forage results.

Take the guess work out your feed program and feed with intended purpose.

I’ll be speaking with real world forage results and target gain for bred females fixing to spring calve.

Know if your forage is meeting, exceeding, or even lacking in energy and protein.

Hope to see yall there!

Something to consider when talking about calf vigor….

Calf vigor is something cow-calf producers look for when watching newborn calves stand to nurse and get around.

As I like to say, weak cows produce weak calves.

When looking at gestational development, the calf’s organs are produced in the first trimester of pregnancy. So, it’s no surprise that calves born to females that have experienced drought are more susceptible to respiratory problems.

Here are some key points to consider in your cow-calf program:

- Selenium is important for muscle strength and suckle reflex.

- Copper and zinc support immune function and epithelial tissue.

- Iodine supports thyroid function and temperature regulation.

- Vitamin E is a big antioxidant that supports muscle strength and immune function.

- Vitamin A supports mucosal immunity.

If you’re experiencing calves that aren’t standing within 30 minutes of calving and nursing, you may have some deficiencies in your program.


Merry Christmas from my family to yours. May your day be blessed and filled with the Lords grace and peace.

Some things to think about, if you feel like your program has plateaued and you know it has more potential. Take a hard look at the operation and keep it simple. DM me if you’re feeling stuck.

Horses produce stomach acid 24/7. That’s why constant forage is key to preventing ulcers. 🐴🍃

If you give this a try, share your experience in the comments!
