TO SUPPORT NORMAL FERTILITY IN MARES
WHICH HORSES BENEFIT FROM OESTROVUM SUPPLEMENTATION?
OESTROVUM is a feed supplement to support fertility in horses and to balance the estrogen metabolism in mares. OESTROVUM is ideal to prepare mares for pregnancy, mares with fertility issues, older mares (12+), stroppy mares with "marish" behaviour.

WHY SHOULD I GIVE OESTROVUM TO MY HORSE OR PONY?
Diseases of the endometrium are a frequent cause of infertility in mares.
64% of clinically healthy mares has a certain degree of fibrosis (endometrosis) in the uterus that aggravates with age (1).
EXCESSIVE LOCAL ACTION OF THE HORMONE ESTROGEN HAS A NEGATIVE IMPACT ON THE HEALTH AND DEFENCE OF THE ENDOMETRIUM (2).
Estrogens are produced and excreted every day. They are broken down in the liver in two phases.
This detoxification can be disturbed when the liver also has to break down many other toxic substances, such as pesticides, medicines and other hormone-disrupting substances in the environment and drinking water.
When detoxification is disturbed, phase II (methylation) is slower than phase I, causing the accumulation of harmful intermediates that have a strong local estrogen effect and negative impact on the health and defence of the endometrium (2).
stimulate the breakdown of estrogens via the liver (METHYLATION)
Broccoli powder helps to reduce the formation ofharmful estrogen intermediates during breakdownin the liver in phase I and stimulates the breakdown enzymes in phase II (3,4).
Folic acid, vitamin B12, choline and betaine areimportant nutrients for the proper functioning ofmethylation (phase II) (5,6).
Cysteine is a building block of the very powerful antioxidant glutathione. When methylation is disturbed, glutathione production will also be disturbed, leading to cell damage and reduced fertility (7).
Natural vitamin E is also a very good antioxidant that helps to prevent cell damage (8).
modulation of the production of estrogens
Linseed reduces the production of estrogens by inhibiting the aromatase enzyme, responsible for the formation of estrogen from testosterone (9).
optimization of genetic potential (EPIGENETICS)
An optimal development of the embryo in the uterus through the supplementation of folic acid, vitamin B12, choline and betaine is of great importance to optimise the genetic potential of the foal in his adult life (10).
