Thunderbrook Agnus Castus (Ground) 1kg – Natural Hormonal Support for Horses

Thunderbrook Agnus Castus (Ground) – 1kg

Agnus castus is the berry of the chaste tree, and Thunderbrook sell it ground, as a straight feed material with nothing else in the bag — no carrier, no filler, no flavouring. Their claim for it is narrow and worth quoting as they put it: it is ideal for temperamental mares, especially those that become unpredictable just before coming into season.

Thunderbrook also say it nutritionally supports temperament in mares and stallions and a healthy hormonal system, and they class it as a feed material for equines rather than as a medicine. Ground rather than whole, it disperses through a damp feed instead of being sorted out and left in the bottom of the bowl. At their rate of 15–20g a day, a 1kg bag runs to roughly seven to nine weeks for one horse.

Performance & Benefits

• Pure ground chaste tree berry — one ingredient, with no carrier, filler or added flavouring.
• Thunderbrook state it supports temperament in mares and stallions and a healthy hormonal system.
• Aimed particularly at mares that turn unpredictable in the run-up to being in season.
• Ground, so it mixes through a damp feed rather than sitting on top of it.
• A 1kg bag lasts roughly seven to nine weeks at Thunderbrook's own feeding rate.

Suitable For

• Temperamental mares, particularly just before coming into season.
• Stallions whose behaviour is thought to be hormonal.
• Owners who want a single named herb rather than a blend of several.
• Feeding into a Thunderbrook chaff or muesli as the carrier.
• Not for pregnant or nursing mares — Thunderbrook say plainly not to feed it to them.

Feeding

• Mix into a damp feed or chaff so it neither blows about nor gets left behind.
