Rebound 3 Syringe 34 gm
Big Dee's Tack and Vet Supplies
$6.75 - $6.95

Under normal circumstances the horse is an extremely efficient machine. However, like so many efficient machines, even the slightest deviation from normal can cause problems. The most likely cause of such deviation in today's horse is stress. One of the first consequences of stress is that the natural balance of flora in the animal becomes disturbed. The flora are important in the breakdown and subsequent absorption of nutrients in order to help ensure that the body's protective system or immunity system remains intact. In addition to stress, chemical additives, worming remedies, and antibiotics are factors which can seriously affect the composition of normal intestinal flora.

Rebound 3 is an oral-dose paste designed to help restore and maintain the desirable micro-organisms in the gut of the horse.

The 30 gram syringe contains 3 full doses.

Beneficial support for horse's digestive system and can help boost their performance. Probiotics improve the efficiency of digestion and improves nutrient absorption.

    Probiotics are useful in the following ways:

    • To give young digestive systems a head start. Foals acquire their intestinal flora from their environment that's one reason why they sometimes eat manure. A probiotic may help populate the young digestive system more quickly.
    • To aid recovery from illness or infection in horses who have received oral antibiotics. Medications that kill harmful bacteria sometimes do collateral damage to beneficial organisms. After the course of antibiotics is finished, a probiotic may aid in faster recovery.
    • To compensate for the effects of stress. Dietary changes, travel and/or competition can put stress on a horse's system. To give the probiotics time to colonize, it is best to start administration two to three days ahead of the stressful event and continue until it is over.
    • To reduce digestive upset in horses susceptible to chronic diarrhea and/or mild colic. Probiotics may stabilize the microflora and promote a healthier environment in the gut. They may also be a good preventive measure in horses who have experienced serious colic.
    • To help old or unthrifty horses better utilize nutrients. A probiotic may improve the efficiency of digestion and aid nutrient absorption in aged horses and others who have trouble maintaining weight.

    Product Details:

    • EquiProbiotics is veterinarian formulated to give you a combination of pre and probiotics of the highest quality and without any fillers or byproducts.
