Warm And Humid Weather Increases The Risk Of Parasites In Sheep And Cattle

Warm and humid weather increases the risk of parasites in sheep and cattle

The latest NADIS1 parasite forecast launched by Boehringer Ingelheim emphasizes that recent warm and humid weather increases the risk of sheep and cattle parasites.

Cattle's strategic worm control is typically applied to weaning calves born in the fall or winter, and calves born in the spring of the second grazing season. Worws should always be managed in accordance with the principles of COWS 5 R - the right product; the right animal; the right time; the right dosage; given in the right way.

The cattle that receive strategic deworming treatment during the early stages of the grazing season should stay in the same ranch throughout the grazing season, or move to a safe ranch, for example, afterwards, when they become available.

Even at low levels of helminth infection, calves and calves of alternative cows will have a 30% lower growth rate . In dairy cows, helminth infections cause a 1 kg drop in milk production per day. In severe infections, there are thrifts,  it will have the situation like loss of physical condition and diarrhea.

Ms. Timothy said: “Calves in their first grazing season are most at risk of diseaseand the heavy worm burden will lead to frugality and potential serious erosion. Not only that, we know that the gutworm's performance for the future Fertility, in particular, has a potential impact.Subclinical growth tests mean that heifers take longer to reach their target weight for first service, and may take longer to enter the calf and often require multiple inseminations.

“Despite popular misconceptions, adult cows are infected with locusts, although they carry a lower worm burden, reduce eggs and show no external signs of disease. However, the impact on productivity has been well documented; in affected animals In the middle, milk production is reduced by at least 1 litre per day, and the additional potential for reduced fertility due to increased calving rate and pregnancy rate reduces overall performance. "


After June, non-vaccinated calves, cattle without effective insecticide programmes, and naive adult cows may develop lung disease ('shell'). Adult cows that have not established immunity through natural challenges over the past few years are also prone to infect lungworm.

Early symptoms include coughing, resting initially after exercise, increased breathing frequency, and difficulty breathing. The affected cattle will soon lose weight and physical condition and should be removed from the infected ranch and disposed of as soon as possible. Adult cows may suddenly experience a sharp decline in milk production.

Cattle observed coughing or showing the signs of potential lungworm infection should be investigated by the farm’s vet and prompt treatment with a suitable, fast-acting, zero milk withhold wormer, such as EPRINEX® Pour On may be advised, depending on the diagnosis.
