Insect Bites

  • Typically insect bite irritation is a condition in both ponies and horses caused by the bites of Culicoides midges.
  • The irritation develops at the sites where the insects feed, mainly the mane, tail and dorsal midline. Ventral midline Irritation may also occur around the ears and head. 
  • These irritations result in itching, which results in rubbing. The itch response is triggered by the immune reaction in the mast cells of the skin, releasing Histimine.

Allergens

  • Under normal living conditions horses are engulfed in dust, mould spores and other foreign substances all day long.
  • In pastures where horses graze there are many different airborne proteins that could mean your horse needs extra support to maintain a healthy skin.  
  • Such triggers leading to the need for support are commonly pollens (often tree), grass, foods (grains and hay)

Hives & Headshaking

  • Hives are swellings on a horse's skin and are an immune response to insect bites and stings or inhaled pollen.
  • They may or may not be itchy, appear minutes to hours to days after exposure.
  • Herdleader works in the same way as for bites, dampening down the immune reaction in the skin.
  • Headshaking can be caused by pollen affecting the nasal cavity.

Information on Feeding & Ingredients

Feed once daily by drawing up the correct amount of the product into the measuring chamber and sprinkling it over a small handful of concentrate which you then give to your horse.

Daily use/Feeding recommendations:
Feed at the rate of 5ml per 125kg bodyweight.
Typically horses (500-600kg) 20-25ml daily, and ponies (350-500kg)15-20ml daily

If you choose to add it to your horse’s whole feed ration then ensure that the liquid is taken and not wasted in the bottom of the feed bucket/bowl.

A 1000ml bottle of HerdLeader is typically 50 days supply for a horse, more for a pony, up to 66 days supply.

Herdleader Oral is a composition of pharmaceutical grade 99% pure Nicotinamide (one of the B3 vitamins) and purified water. No other ingredients. Nicotinamide is the only one of the various forms of Vitamin B3 that suppresses the immune response that releases the irritant histamine.

Nicotinamide is a water soluble natural vitamin. It is very safe. Excess vitamin is expelled through urine. It does not accumulate in the body.

The level of Nicotinamide is 270mg/ml. This means that a 500kg horse receiving 20ml per day of Herdleader Oral is fed at the intended rate of 11mg Nicotinamide per kilo of bodyweight.

The current FEI banned and controlled substances list does not include nicotinamide. Rest assured, Herdleader Oral and Lotion contain no prohibited substances.

If it’s been a mild winter, for example, midges will be active earlier than after a prolonged cold season.  Then there are environmental factors, i.e. where the horse is kept, low lying ground, proximity to water, etc.  Add in all those other measures that are available, factor in how early in the year you started the supplement & then, of course, each animal will react to the same irritant individually. 

Now, more technical information for you. Nicotinamide works in two different ways.  Firstly & most well known is the dampening down of the immune system & therefore the urge to scratch/rub itchy parts. Secondly,  it works to thicken the skin.  The first effect - relating to the immune system - builds up quite quickly, in a matter of days, while the second takes effect much slower.  The skin’s thickening is caused by increasing numbers of fat cells it contains & this process is ongoing, it can take a month or more. 


Herdleader Summer Itch Relief is completely safe to feed to pregnant mares at any stage. Indeed the B3 vitamins generally are important and useful to the developing foal.

The short answer is yes. The active ingredient in Herdleader, nicotinamide, will not affect metabolic processes associated with laminitis. Herdleader contains no carbohydrates that can affect insulin resistance and hormonal imbalances.


Herdleader Summer Itch Relief delivers a higher dosage (11mg/kg bodyweight) of Nicotinamide than other brands and yet its cost in-use is less. Typically its cost for a horse is 68p/day compared to 75p/day for the Cavalesse brand for example.

So far so good

I’ve started this during the spring to get it into my horses system. He suffers from severe allergy reactions and today, he went out naked for the first time in 2 years. I expected him to start chucking himself at the walls as usual when he’s been out where there are flies but I was surprised when he came in and just tucked in to his haynet! It is too early in the season to determine if this is making a huge difference but today it seemed to do the trick. Order arrived quickly & efficiently.

Not quite the five stars we hope for but Sarah has since placed more orders, so we hope her horse is still doing well.

Best result in years!

Have been trying for years to get a grip on an itchy horse who usually has no mane or hair on his face by this point in summer. Tried various options, supplements, injections. Have used Herdleader this year (been very strict about daily usage and do give a tiny bit more then on the bottle as he's a big lad) and what a difference. We have mane and hair! Other folk have noticed immediately upon seeing him. Noticeably less itchy overall. Deffo would recommend trying.

Itch relief

I'm giving herdleader summer itch relief to my connemara pony and I've started to see an improvement after 2 weeks of use. I'm still using a fly rug 24/7 but his skin under the mane and top of tail is showing a definite improvement and he isn't as desperate to rub himself. What a relief for both of us! Thank you.

We are delighted that you've seen such good results, especially after only two weeks of use. Thanks for the update.

Effective

Has alleviated the itching problem for 2 itchy horses. Appears to have cured one and reduced itching on a sweet itch problem horse.

So pleased to receive this news, thanks for the 5 stars! Two more comfortable horses plus one relieved owner no doubt.

Brilliant

Been using this product for a few months now and have definitely seen a difference in my Dartmoor. Previous years he’s been so irritated and when given the chance will scratch on anything, especially when he comes into the stable. He didn’t itch his face at all when stood outside his stable the other day (previously he wouldn’t stop itching). The customer service is also brilliant. I had a faulty bottle arrive and they sent out a brand new one the same day.

Hello & thank you, we appreciate your kind words. Delighted that your Dartmoor is no longer distressed by those pesky critters.

Excellent product

I have been using this for my sweetish pony. It’s working brilliantly with no symptoms this year so far. Also a great price for such a large bottle.

Many thanks for a great review Debbie. Such a good outcome for your pony makes us happy too.

It really works!

I bought this product last year to help with a loan horse who suffered with rubbed tail and mane. It made a great difference and as well as using fly sheets we are hoping it will continue into this year. Everyone remarks on how good his summer coat looks as well.
Have recommended to friends so hope they have the same success.

Another 5 star review, thank you Sue. Herdleader continues to attract new customers so the good word is spreading. We thank everyone who recommends us to their friends.
