Foot-and-mouth disease (FMD) is an infectious and sometimes fatal viral disease that affects cloven-hoofed animals, including domestic and wild bovids. The virus causes a high fever lasting two to six days, followed by blisters inside the mouth and near the hoof that may rupture and cause lameness.
FMD has very severe implications for animal farming, since it is highly infectious and can be spread by infected animals comparatively easily through contact with contaminated farming equipment, vehicles, clothing, and feed, and by domestic and wild predators.Its containment demands considerable efforts in vaccination, strict monitoring, trade restrictions, quarantines, and the culling of both infected and healthy (uninfected) animals.
The preliquisite for high economic returns is raising a healthy pig herd.
Unfortunately, today’s pig farmer does it as a by the way; keeps the pig under very unhygienic environment, a fertile ground for diseases .
Economic losses due to diseases arise as mortality and reduced growth rate.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. Aim
COWS aims to provide the best available, evidence-based information
and advice to the cattle industry in relation to the sustainable control
of parasites in cattle.
We are an independent industry led group
www.cattleparasites.org.uk
Twitter: @COWSworms
4. Why?
Currently, anthelmintic resistance is common in sheep, less so in cattle
However, suspect resistance has been reported in the liver fluke (to
triclabendazole) and the intestinal worm, Cooperia (to macrocyclic
lactones).
COWS is following the lead of SCOPS in the provision of up-to-date,
evidence-based advice on parasite control and the management of
resistance to the cattle industry
6. Gut worms – Parasitic gastroenteritis (PGE)
• Known as Nematodes or roundworms
• Two main species of gut worms
• Ostertagia ostertagi (Abomasum)
• Cooperia oncophora (Small intestine)
• Greatest threat to young stock (1st season grazing
calves)
• Scour, weight loss, failure to thrive
• BUT adult productivity can be affected
• Reduced food intake, growth rates, milk yield
7. Epidemiology – gut worms
• All these species have direct life cycles
• Eggs shed on pasture in dung
• Develop to L1----L2----L3 within dung pat
• Development is dependent on temperature (it proceeds faster
when it is warmes).
• L3 is infective stage, which migrates from the dung to the pasture
• L3 can survive over winter on pasture
• Control based on preventing build up of L3 on pasture
• Ingestion of large numbers of L3 can cause disease
• Disease typically seen from July onwards

Turnout April; Housing November; No treatment or moves
Over-wintered larvae
11. Lungworm
• One species (Dictyocaulus viviparus)
• Highly pathogenic
• Very unpredictable epidemiology
• L1----L2----L3 develop in the dung
• Temperature dependent development
• L3 infective stage, spread by Pilobolus fungus, can reach
fields where no cattle have previously grazed
• Cattle develop strong immunity, but can be short lasting
(≤6 months) in the absence of exposure
• A vaccine is available to protect cattle
13. Liver and Rumen fluke
• Highly pathogenic in sheep, the same parasite infects
cattle
• Major cause of production losses in cattle
• Indirect life cycle – transmitted through a mud snail
• Life cycle dependent on temperature AND rainfall
• Cattle most at risk from infection in the Autumn
• Rumen fluke is relatively new and becoming quite
common
• The juvenile fluke can cause clinical disease, but the adults do
little damage.
• Transmitted by the same mud snail vector as liver fluke
17. External parasites
• Lice
• Long winter coats, close contact, warmth and dark conditions
means lice are mainly a winter problem
• Mites
• Most common type is Chorioptic mange, hair loss and irritation
around base of the tail and the heels
• Flies
• A summer problem
• Biting flies (horse flies and stable flies)
• Nuisance flies (head and horn flies)
• Can transmit infections and bother cattle, reducing feeding time
• Ticks
• Transmit disease such as Red Water Fever
• Damage hides

20. Control measures – Identify risk
• What parasites are on the farm?
• Assess pasture & cattle risk
• Key time points - turnout, mid-summer,
housing
Parasite Time to acquire immunity
Ostertagia 2 grazing seasons
Cooperia 1 grazing season (3-6 months)
Lungworm 1-2 months, but repeat exposure is required to
maintain immunity
Liver fluke None

22. Control measures – Treat/manage appropriately
• Strategic or therapeutic policy?
• If wait and see is choice then monitor regularly
• Determine which products work well on your farm
COWS strongly advises that farmers discuss product choice with their
vet or suitably qualified person (SQP) as part of their herd health plan
23. Control measures – minimize the risk of
resistance
• Dose properly
• Weigh animals
• Calibrate dosing equipment regularly
• Aim for good parasite control at housing
• Implement an appropriate quarantine programme
24. The 5 R’s for the effective use of wormers
The right product for the right type of worm
The right animal
The right time
The right dose rate
Administered in the right way
25. Incorrect parasiticide administration
• Under-dosing
• Poor efficacy when treating clinical cases
• Reduced persistency & duration of protection
• Increased risk of resistance
• Over-dosing
• Risk of toxicity
• Withdrawal periods for meat and milk are
determined using the recommended dosage;
higher dosages mean that withdrawal periods
should be increased
27. Current resistance / Poor efficacy status
Parasite: parasiticide Solution
Cooperia spp to macrocyclic lactones
(Intestinal worms)
In FGS calves, treat with LEV or BZD
or administer concurrently with ML
F. hepatica to triclabendazole (TCBZ)
(Liver fluke)
Use an alternative flukicide
P. ovis to macrocyclic lactones
(Psoroptic mange)
Isolate infested animals and repeat
treatment until cured
28. Key messages
• Know the critical danger time - peak exposure to infective stages
• Think about life cycles and intervention points
• Block transmission
• Avoid high risk pasture at key times of year
• Know what is in veterinary medicines
• Talk to your vet or SQP
• Use drugs correctly
• Combine management strategies with drug control
• Think about quarantine measures
