Lameness
Lameness is one of the most common issues seen in the U.K dairy herd, with clear repercussions on animal welfare and productivity. A lame cow may require regular foot trimming and medicines prescribed to treat any pain, inflammation and infection.
The total cost of lameness in a herd is not just associated with treatment. When costs are calculated, the impact is associated with reduced milk yield, reduced fertility and production losses.
Parturient paresis
Parturient paresis, commonly known as milk fever or hypocalcemia, is a metabolic disorder that affects dairy cattle, particularly around the time of calving. It occurs when there is a sudden drop in blood calcium levels as the cow transitions from late pregnancy to lactation. This drop in calcium can lead to a range of symptoms, including weakness, inability to stand, decreased appetite, and in severe cases, paralysis.
Parturient paresis is a critical concern for dairy farmers because affected cows may experience difficulty calving, have reduced milk production and be more susceptible to other health issues. Prompt recognition and treatment are essential to prevent complications and ensure the cow’s well-being.
Mastitis
Mastitis is an inflammation of the mammary gland that affects the health and welfare of ruminants. It is a common and serious condition that can cause significant losses in milk production and profitability for farmers.
It is often caused by bacterial infections and its symptoms may include swelling of the affected mammary gland, abnormal milk production (such as clots or changes in colour or consistency) and fever. It can lead to serious complications including increased risk of udder infections in the future, decreased fertility and reduced milk production. Treatment typically involves the use of anti-inflammatories, antibiotics and supportive care, such as milking the affected gland regularly to help remove any infected milk. 50% of mastitis in early lactation comes from the dry-period, highlighting the importance of a smart dry-off management to tackle this disease.
