What is allicin?
Allicin is a sulphur-containing compound derived from garlic. It has attracted attention as a livestock feed ingredient because of its antioxidant properties, and it is widely studied for its antimicrobial properties. In research, allicin is described as bacteriostatic: it slows down bacterial growth rather than killing bacteria, while beneficial lactobacilli are left virtually untouched.
AHS boluses deliver allicin in a stabilised, highly concentrated form, so it remains active in the cow for a longer time.
How allicin supports your herd
- Gut health – contributes to a balanced gut flora and good digestion.
- Antioxidant – helps cattle cope with oxidative stress, for example during heat stress, transport or high milk production.
- Natural resistance – supports the natural resistance of cattle, and of calves early in life.
- Udder health and milk quality – used by dairy farmers to support udder health and a low somatic cell count (SCC).
Feeding advice
- Elevated cell count after milk recording: give 1 AHS-10.
- Older cows with a persistently high cell count: give 1 AHS-28.
- Cows that start to show flakes in the milk: give 1 AHS-10 straight away.
- Cows with a hard, swollen quarter: give 100 ml Liquid Booster plus 1 AHS-10 (older cows: 1 AHS-28), and consult your vet.
Experience from practice
Dairy farmers who give an AHS-10 at the first signs of udder problems report that their cows keep eating well and return to their previous milk yield. More flakes may come out at first; strip the quarter thoroughly at every milking.
Always keep an eye on three points:
- the cow is eating well;
- milk production is rising again;
- the cow has no fever.
If one of these points is not met, contact your vet.
Complementary feed: we therefore make no health or efficacy claims. The experiences mentioned come from livestock farmers in practice. This information is general and does not replace a veterinary diagnosis or advice.
All our AHS products are complementary feeds with no withdrawal period for milk and meat.
