Conditions

From a symptom
to the science.

Practical, educational notes on the dairy health challenges our products are built around. Not a substitute for veterinary advice.

Anoestrus & Silent Heat in Dairy Cattle

When cows fail to show clear signs of heat, or do not cycle at all after calving, rebreeding is delayed, calving intervals lengthen and lifetime productivity falls.

Fatty Liver, Ketosis & Negative Energy Balance in Dairy Cattle

Around calving, cows often eat less while their energy needs rise. This negative energy balance can lead the body to mobilise fat, which may contribute to fatty liver and ketosis.

Heat Stress in Dairy Cattle

When temperature and humidity rise, cows struggle to lose body heat. Heat stress reduces feed intake, milk yield and fertility, and affects cow comfort and health.

Internal Parasites & Worms in Cattle

Gastrointestinal worms and liver fluke are common internal parasites that can quietly reduce growth, milk yield and body condition, often before obvious signs appear.

Lameness & Hoof Health in Dairy Cattle

Lameness, difficulty or reluctance to walk, often from hoof or leg disorders, is a major welfare and productivity issue, reducing feed intake, fertility and milk yield.

Lumpy Skin Disease in Cattle

Lumpy skin disease (LSD) is a viral disease of cattle and buffalo, spread mainly by biting insects. It causes fever, firm nodules across the skin and swollen lymph nodes, and often a sharp fall in milk yield.

Mastitis in Dairy Cattle

Mastitis is inflammation of the udder, usually caused by infection. It is one of the most common and costly conditions in dairy herds, affecting milk quality, yield and cow comfort.

Milk Fever in Dairy Cattle

Milk fever (hypocalcaemia) is a metabolic condition seen around calving, when a cow’s demand for calcium rises sharply for milk production and blood calcium can fall faster than the body replaces it.

Poor Milk Let-Down During Stress

Milk let-down is a reflex that can be disrupted by stress, discomfort or poor health, leading to incomplete milking and reduced yield even when the cow is producing milk.

Post-Calving Weakness & Downer Cow Syndrome

A ‘downer cow’ is one that remains unable to rise despite initial treatment. Around calving this can follow metabolic upset, nerve or muscle injury, or prolonged recumbency.

Recovery Support After Disease & Stress in Cattle

After illness such as FMD, LSD or PPR, or after calving, heat or vaccination stress, animals often need a recovery phase to regain appetite, strength and productivity.
