Parasitic gastroenteritis (PGE), caused by gastro-intestinal roundworms, is a common and economically significant issue in both dairy herds and beef systems. But worming isn\u2019t just about blanket treatments. Effective control requires a blend of strategic anthelmintic treatments, targeted monitoring, and smart pasture management.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What is worm burden?<\/strong>&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Worm burden refers to the number of internal parasites\u2014typically gastro-intestinal roundworms\u2014in a cow\u2019s digestive tract. Parasitic gastroenteritis in cattle is caused by an accumulation of these parasites, particularly in young or susceptible animals. The severity of the burden depends on a cow\u2019s immunity, pasture conditions, farm history, and exposure to infective larvae.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Parasitic worm species<\/strong>&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Some of the most common species of worms in UK cattle include:\u00a0<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><em>Ostertagia ostertagi<\/em> \u2013 the small intestinal worm&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><em>Cooperia spp.<\/em>&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><em>Dictyocaulus viviparus<\/em> \u2013 lungworm&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><em>Fasciola hepatica<\/em> \u2013 liver fluke (requires an intermediate host, such as the mud snail)&nbsp;<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Signs of worm infections<\/strong>&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Clinical symptoms of worm infections vary between animals. Keep an eye out for:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Loss of appetite and reduced feed conversion&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Poor growth rates or weight loss&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Scouring (diarrhoea)&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Anaemia or bottle jaw&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>General signs of gastroenteritis in cattle, such as discomfort and dullness&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These signs are especially prevalent in calves or weanlings facing their first parasitic challenge.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>When to treat: Age-based risk<\/strong>&nbsp;<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>First grazing season \u2013 highest risk<\/strong>&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Calves grazing for the first time are most vulnerable, especially on dirty pastures previously grazed by infected cattle. Without immunity or milk supplementation, they rely solely on potentially contaminated forage.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Second grazing season<\/strong>&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Although partially immune, yearlings still suffer from reduced liveweight gains due to low-level parasite loads. Monitor live weight to ensure growth milestones are achieved.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Adult cattle<\/strong>&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Most adult cattle are immune to gut and lungworms after sufficient exposure. However, liver fluke remains a risk as there is no natural immunity. Cows grazing fluke-prone pastures should receive targeted treatment at least once annually.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Bulls are more susceptible and should be treated before the breeding season for optimum performance.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Practical methods of worm control<\/strong>&nbsp;<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. Strategic grazing and stocking density<\/strong>&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Reduce animal density to limit ingestion of larvae near faecal matter. Implement rotational or strip grazing to keep cattle away from infected pasture zones.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Leader-follower systems (young stock graze ahead of adults) allow susceptible animals to access cleaner, taller grass first\u2014minimising parasite exposure.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. Regular monitoring: Faecal testing &amp; growth rates<\/strong>&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Routine fecal egg counts (FEC) and fecal flotation methods are vital tools to assess the parasite load. Combine this with regular weighing to track performance and detect any drop-off in live weight that may signal internal stress.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong><em>How to take faecal samples<\/em><\/strong>&nbsp;<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fresh (&lt;1 hour old)&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Airtight, labelled container&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Kept cool (not frozen)&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Deliver to a lab within 48 hours&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>For lungworms, submit samples as soon as possible&nbsp;<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>When to use anthelmintics<\/strong>&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Anthelmintic treatments are a key tool\u2014but should be used only when necessary. Over-reliance leads to drug resistance and long-term reduction in product efficacy. Consider:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The type of parasite&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Stage of its life cycle&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Season and treatment history&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Results from fecal egg count or veterinary advice&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Using macrocyclic lactone (ML) products (e.g. ivermectin) effectively can control a range of internal and external parasites. However, misuse or repeated use can lead to resistance. Always rotate classes of wormer responsibly.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How to treat worms in cattle<\/strong>&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To maximise efficacy and reduce resistance:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Accurate live weight: Use scales or weight bands\u2014avoid guessing&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Correct calibration: Ensure dosing equipment is accurate&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Full dose always: Even when using multiple products&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Adhere to withdrawal periods before slaughter or milk collection&nbsp;<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Worming methods<\/strong>&nbsp;<\/h3>\n\n\n\n<h4 class=\"wp-block-heading\"><strong><em>Pour-ons<\/em><\/strong>&nbsp;<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Apply to clean, dry skin&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Avoid treatment before rain (unless waterproof)&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Avoid manure-covered areas&nbsp;<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><strong><em>Injectables<\/em><\/strong>&nbsp;<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Shake product if needed&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Disinfect between uses&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use clean syringes and sterile technique&nbsp;<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><strong><em>Boluses<\/em><\/strong>&nbsp;<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use proper applicator&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ensure bolus is swallowed safely&nbsp;<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><strong><em>Oral drenches<\/em><\/strong>&nbsp;<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Deliver into the rumen&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Calibrate guns with the actual product (not water)&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Avoid bypassing the digestive system&nbsp;<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Resistance to worming treatments<\/strong>&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Resistance develops when worms survive low doses or frequent, unnecessary treatments.
