Pro Youngster

A premixture for horses.

The ultimate equine forage balancer for Youngstock. Delivering optimal key vitamins, minerals & amino acids to support the growth and development of youngstock.

Our high specification formulas are carefully balanced using optimum ratios defined by the National Research Council. Targeting only the deficient minerals in forage.

The Pro Youngster is manufactured in a UFAS (Universal Feed Assurance Scheme), BETA NOPS (Naturally Occurring Prohibited Substances), FEMAS (Feed Materials Assurance Scheme), ISO 22000 ( Food Safety Management System) certified state-of-the-art premix manufacturing facility. Pro Youngster is produced using the highest quality feed assured ingredients under strictly controlled production conditions and conforms to the requirements of EU and UK legislation governing the manufacture of animal feeding stuffs.

This superior powdered equine balancer has been specifically formulated to contain the commonly deficient minerals, vitamins and amino acids at the optimum levels required to support the increased nutritional demands of the growing equine.  These key ingredients are critically important for building strong bones, tendons, ligaments, muscles, teeth, and vital organs.

Also includes Vistacell to support gastrointestinal health and integrity.

We recommend additional micronised linseed meal throughout the winter months or if a horse is fed predominantly hay/haylage , this is for the essential fatty acids that a horse may be short of when grass is restricted. Essential Fatty Acids cannot be manufactured within the body & must be present in the diet.

  • The support of the increased nutritional demands of the growing youngster
  • Development & growth of young bones and joints
  • Healthy robust hooves

Please note our guidance on the use of Salt: We do not add salt directly to our formulations.

Chloride in salt is naturally quite abrasive. So adding salt can lead to rapid degradation of vitamins used in our mixes if exposed to light, moisture and heat etc.

Addition of salt could considerably reduce the shelf life of our products. Our products are packed and sealed in carefully controlled packing facilities at our mixing house. We cannot guarantee how products are stored once opened by our customers.

We have a fast turnover of products and all our mixes benefit from long shelf lives. Customers can feel confident that their products will remain fresh and free from degradation.

Our Balancers and Premixes are formulated with the specialist guidance of World leading nutritionists at the Professional Mixing House Company we use.

We recommend all horses should have free access to salt. However, a salt lick alone cannot be relied upon to cover maintenance & sweat requirements. Many horses do not choose to use the lick enough.
The amount of salt needed is variable depending on how much the horse sweats.

For example a 500 kg Horse needs 10g of sodium per day (25g of salt) for maintenance needs, this is without exercise or sweating on hot days.
1 – 2 tablespoons of salt per day, added to the horses feed is a reasonable amount to cover maintenance requirements. 

Working horses will require additional electrolytes. Dissolving the salt in water & spraying on to hay, can be an alternative option for picky eaters.

Suggested intake:

3 x 50 ml size scoops (= approximately 140g) for a 500 Kg horse per day.

1.5 x 50 ml size scoops (= approximately 70g) for a 250 Kg horse per day.

As a guide a 1 x level 50 ml scoop of Pro Youngster provides approximately 46.6g of product. Therefore three x 50 ml scoops is about 140g.

How long will one 4.2 Kg pack of Pro Youngster last?

It will last about 30 days fed at the recommended rate for a 500 Kg horse.

It will last about 60 days fed at the recommended rate for a 250 Kg horse.

Pro Youngster is a powdered supplement which we recommend is mixed with a damp base feed, such as alfalfa, beet pulp, wheat bran and/or copra meal etc.

When feeding for the first time, it is recommended to introduce gradually over a period of 5-7 days.

    I’ve been using the Pro Youngster for a couple of months now for my new 3½ year. He hadn’t previously been given a hard feed, but took to the Pro Youngster without any problems.

    PE was originally recommended to me by an equine podiatrist. I had been using the Pro Hoof Platinum for several years for my previous horse and more recently he was also on the Pro Joint Supreme. Both of those products were fantastic.

    I’d highly recommend PE. Great products that work, with quality ingredients, nothing hidden.

    We have been Using Pro-Youngster for our mare for the last several months of her pregnancy, and she has remained in very healthy condition. Her filly foal was born on 25/5/22. The foaling was trouble-free and the foal was up and feeding within half an hour. We plan to continue with Pro Youngster during lactation and for the foal as she grows.

    My Eriskay filly is now rising three and has been on Pro Youngster since birth (or before as I fed it to the mare, as advised by Progressive Earth). They find it very palatable, and have excellent feet and lovely coats, and the youngster is developing into a really nice pony.

    My two year old was apprehensive at first but now he loves it. It is about a month worth in the pack and it does smell lovely. My boy is so much more relaxed and happy.

    Love your products but have to stop using them as I live in ireland and there is extra VAT and import tax slapped on over here so it makes it too expensive

      Hi Maria
      Thank you for your feedback. Brexit has badly affected so many of us. It is so sad for us to lose our valued customers from the EU but we completely understand your dilemma.
      We hope that in time the government sorts this mess out!

    I started using this product for my mare who has a foal at foot as I loved the results it gives with my babies , I thought I’d try it.
    She’s always had bad feet… 6 months on this an she’s not only got much better feet/skin/coat she’s also gone down a shoe size. My farrier is very impressed.
    I wouldn’t feed my newly weaned foals/young stock/mares in foal anything else after using this product for 9 months and owning horses for 31 years.
    All my horses love it and so do I.
    Thank you progressive earth for a fantastic service you provide me.

    I was happy with the advice from Progressive Earth about this mineral balancer. My mare has done well on it. What I really appreciate about these products is I can add them to soaked basic grass nuts as a feed without having to give a bagged feed which most often contain products that horses should not be fed. Thanks for giving us another option PE!

    Palatable balancer, my youngster is a fussy eater but has no problem eating this. She is growing very steadily with no growth spurts and has never looked poor or ‘bum high’. I would recommend this company and product.

    After using Progressive Earth for our mare Keeva I was confident to get this young stock supplement for my new Two year Welsh section D filly Nia, she had rubbed her mane out on a hay feeder before I bought her last July and she has a beautiful thick long mane again and her growth and development has been excellent!
