Bolus

Fertility

OvuMax Bolus is a high-quality feed supplement for cattle, developed for use in the period leading up to insemination. The bolus contains a carefully selected blend of botanical ingredients that support liver function, energy metabolism, digestive function and antioxidant status.

Thanks to its slow-release formula, the ingredients are gradually released over approximately 21 days, providing consistent individual support, regardless of feed intake.

OvuMax Bolus supports the cow during the pre-breeding period and helps maintain the physiological balance associated with the natural expression of oestrus.

Challenge

Metabolic and physiological challenges can affect the normal expression of oestrus in cattle.
Factors such as a negative energy balance, liver strain, heat stress, oxidative stress and reduced feed intake may influence cycle recovery, reproductive function and the expression of oestrus.

In practice, this can contribute to:

Missed oestrus
Less pronounced signs of oestrus
A longer interval to successful insemination
A longer calving interval
Reduced reproductive performance at herd level

Solution

OvuMax Bolus provides targeted nutritional support during the period preceding insemination. Its carefully selected botanical ingredients support key physiological processes involved in normal reproductive function and natural expression of oestrus.

The formula supports:

Liver function
Energy metabolism
Digestive function and feed utilisation
Antioxidant protection
Physiological balance during the reproductive cycle

By supporting these processes, OvuMax Bolus helps create favourable nutritional and physiological conditions for the natural expression of oestrus.

Important: OvuMax Bolus is not a hormonal product and does not induce or synchronise oestrus. Instead, it provides nutritional and physiological support during the period leading up to insemination.

Release: The bolus provides a gradual release of ingredients over approximately 21 days

Uptake: Individually administered, ensuring consistent intake regardless of feed consumption

Withdrawal period: no withdrawal period for milk or meat

Ingrediënts

Milk thistle (Silybum marianum), artichoke (Cynara scolymus) and boldo (Peumus boldus)
Properties of milk thistle, artichoke and boldo

Liver function and energy metabolism:
Around calving and during early lactation, the liver is placed under considerable metabolic stress due to negative energy balance and increased fat mobilisation. Good Optimal liver function is essential for maintaining energy supply and supporting the many physiological processes involved in the resumption of the oestrous cycle and reproduction performance.
Silybum marianum, Cynara scolymus and Peumus boldus work together as a botanical complex formulated to support liver function. This combination provides targeted nutritional support for dairy cows during periods when metabolic demands are high and fertility requires additional support.

Turmeric (Curcuma longa) and Ginseng (Panax ginseng)
Properties of turmeric and ginseng

Antioxidant protection:
Oxidative stress can negatively affect fertility in dairy cows, by impairing oocyte quality, embryonic development, postpartum recovery, and overall reproductive performance.
Curcuma longa contains curcumin, a bioactive compound renowned for its antioxidant properties, which helps protect cells against oxidative damage and supports cellular health.
Panax ginseng contains ginsenosides, bioactive compounds that are associated with antioxidant, immunomodulatory and adaptogenic properties, helping animals cope stress while supporting overall health and resilience.

Fennel (Foeniculum vulgare), Fenugreek (Trigonella foenum-graecum) and Thyme (Thymus vulgaris)
Properties of fennel, fenugreek and thyme

Support for digestion and nutrient utilisation:
Efficient digestion is fundamental to maintaining energy balance, supporting the recovery of the oestrous cycle, and sustaining consistent milk production. In dairy cows, optimal nutritional status is a key factor in reproductive health and overall performance.
With carefully selected plant-based ingredients such as Foeniculum vulgare, Trigonella foenum-graecum and Thymus vulgaris, Ovumax bolus supports digestive function and promotes efficient nutrient utilisation, helping to build a strong metabolic foundation during periods of increased physiological demand.

Hop (Humulus lupulus)
Properties of hops

Support for physiological processes associated with oestrus
Humulus lupulus, commonly known as hops, naturally contains a range of bioactive plant compounds, including bitter substances, polyphenols and prenylflavonoids. Some of these compounds have been reported to exhibit phytoestrogen-like activity.
This phytoestrogen-like activity is consistent with the role of oestrogen in the normal processes associated with the cow’s reproductive cycle. For this reason, Humulus lupulus has been included in Ovumax Bolus as a complementary botanical ingredient to support cows during the period leading up to insemination.
