Effectiveness of preparations based on Yarrowia lipolytica yeast and esters on the reduction of stomach ulcers in race horses.

Goal of the study

The study aimed to verify whether the administration of supplements based on Yarrowia lipolytica yeast could have a healing effect on the of race horses’ ulcers. The study was conducted at the Służewiec Horse Racing Track in Warsaw from August till November 2014.

Course of the study

The study involved 15 racing horses training on a regular basis. The horses underwent a gastroscopic examination qualifying for the program and after the supplementation. During the study, horses received one of the following supplements: Equinox, Gastro Formula or Electrolyt Balance and dried apples as a placebo.

Results

In 4 horses receiving the Equinox supplement, ulceration was reduced. Of the four horses receiving Gastro Formula supplement, two horses had a significant reduction of the erosions, one showed no change, and one showed a slight worsening of ulceration. In three horses receiving the Electrolyte Balance supplement, ulceration was reduced. In the control group, three out of four horses showed worsening of ulceration, one of them showed improvement.

Yarrowia lipolytica based supplements for horses can potentially help in the treatment of horse ulcers.

Effectiveness of Gastro Formula in reducing stomach ulcers in racehorses

Goal of the study

The research was carried out in the Służewiec Horse Racing Course in Warsaw from August till November 2014.

Course of the study

The study involved racing horses in training and racing on a regular basis. Horses were reported by trainers or owners as showing reduced exercise capacity or worse condition when compared to other horses in the stable.
The group consisted of 8 British Thoroughbreds and one purebred Arabian horse, aged from 2 to 6 years. Eight horses raced in flat races, one in fence races. Most of the horses during tests raced more than once (from 1 to 6 races).
The horses underwent a gastroscopic examination qualifying for the program and after the end of supplementation. The period of supplementation with Gastro Formula lasted 8 weeks. The horses were divided into two groups.
Experimental group – 5 horses received Gastro Formula (80% Yarrowia lipolytica yeast + 20% Omega-3/6/9 esters)
Control group – 4 horses receiving placebo (granulated dried apple)
Gastroscopy was performed using the Portascope PVS3M gastroscope. A 5-point scale was used to describe the changes.

Results

Horses from the experimental group before the start of supplementation had ulceration of II, III and IV degree. After the end of the 8-week supplementation, in 2 horses with II degree ulceration, there was no reduction of erosions, but the lesions stopped bleeding. In the horse with IV degree of cervical erosion, lesions were reduced to II degree. In the resulting two horses, lesions stopped bleeding and showed a slight reduction in the degree of ulceration.

The effect of supplementation with Yarrowia lipolytica yeast on the quantitative and morphological characteristics of the blood and horse skin appendages

Goal of the study

The research was carried out in 2012 (April – August) on a group of 34 horses (22 mares and 12 yearlings) from stud farm located in Prudnik, by the research group from the University of Life Sciences in Wrocław.

Course of the study

Supplementation with yeast lasted 4 months. Examinations of skin appendages (hair, manes, and hooves) included trichoscopic (hair, mane) and radiological (hoof) examinations. In the case of hooves, X-ray examinations were carried out with and without stress, and based on this, the characteristics of optical variation was presented. This allowed to assess the impact of supplementation on the horse’s hoof.

Results

After a four-month supplementation, at yearlings:

  • elasticity of the front wall of the hoof significantly increased while maintaining, without significant differences in shape, the coronet area;

  • the sole of the hoof became slightly more elastic;

  • improvement of the hoof front surface and the coronet;
