Cow deworming schedule and rules: Know the correct method Worm infection is one of the biggest enemies of cow health and productivity. If deworming is not given regularly, the cow becomes weak, loses weight, and milk production is also disrupted. This article contains the correct deworming schedule, method, and ways to avoid common mistakes. Symptoms of worm infection Gradual weight loss, reluctance to eat Fur coat becomes dull and rough Worms appear in loose stools or feces Swollen abdomen but dry body Pale membranes under the eyes (signs of anemia) Deworming schedule by age Calf (3 weeks to 6 months): The first deworming should be given 3 weeks after birth. Then once every 4-6 weeks, until it is 6 months old. Growing cattle (6 months to 1 year): Deworming should be done once every 2-3 months, as the immune system is not yet fully developed at this time. Adult cattle/cows: Usually 2-3 times a year (every 4 months) is sufficient. However, it is especially important to give it after the rainy season and at the beginning of winter, as worm eggs are more active during this time. Pregnant cows: It is better to avoid deworming during the last three months of pregnancy, but no medication should be used without the advice of a veterinarian. Correct method and precautions The dosage of the medicine should be determined according to the weight of the cow — it is dangerous to give it by guesswork Giving deworming on an empty stomach is most effective It is better to use different groups of medicines occasionally rather than using the same type of deworming repeatedly, as this does not build up resistance in the worms It is safe not to use the milk of that cow for sale for at least 72 hours after giving deworming (the time mentioned on the medicine label should be followed) Common mistakes Giving the same dose to all cows at the same time, not considering the difference in weight Giving deworming only when symptoms appear, not following a regular schedule Assuming that there are no worms without a stool test Not keeping the farm environment clean, which leads to repeated infections Preventive management In addition to giving deworming, keeping the farm environment clean is equally important: Cleaning dung regularly and not storing it Changing pastures periodically (rotational grazing) Keeping water sources clean, avoiding stagnant dirty water Conclusion Deworming It is not just a matter of applying medication, it is part of a regular management. Following the right schedule has a positive impact on the health of the cow, weight gain, and milk production.
