In mid-May, after the ewes have finished lambing, it's an ideal time to administer a new type of anthelmintic called Afordin (also known as Worm Buster). This treatment effectively eliminates internal nematodes, external parasites, larvae (such as those causing epilepsy), grasshoppers, and fly infestations. The recommended dosage is one sachet (5g) per 50kg of body weight, which can be mixed into the feed. Repeat the treatment every 7 to 10 days, and avoid using medicated baths once the parasites are controlled. Lambs born in spring should be dewormed in the fall, and if necessary, always strictly control the dosage. In areas where schistosomiasis is common, drugs like nitroprusside can be used during spring and autumn to prevent insect infestations.
During summer, proper grazing management is crucial. Sheep tend to gather in hot weather and may not eat enough. To manage this, graze early in the morning and late in the afternoon, with a rest period at noon. Morning grazing times should be adjusted based on dew levels—more dew means delaying grazing. Dewy grass can carry parasites, increasing the risk of disease, and also causes bloating in sheep. It’s best to graze when the dew has dried. Around 10:00 am, before the day gets too hot, start grazing. Move to pastures around 2:30 pm and return by 7:00 pm, taking a break from 11:00 pm to 2:30 pm. In the morning, use poor-quality grass on sunny slopes, and better quality pastures in the afternoon. On hot, sunny days, choose dry, well-ventilated areas or shaded spots to avoid overcrowding and stress. On rainy days, graze on flat ground and ensure sheep eat 4–5 full meals daily. Early and late evenings are best for grazing in tender, grassy areas using a "star" grazing method, encouraging multiple feeding sessions. Always provide salt and clean water daily—1–6 times a day. Use running water or well water, avoiding stagnant or dirty water to reduce parasite risk. Prevent sheep from lying in damp areas to avoid rheumatism, and avoid grazing in the wind during rain to protect their faces from getting wet. After the summer solstice, continue grazing in light rain but avoid heavy downpours. After rain, move sheep to hillside pastures and use the "star" grazing method to help dry their wool quickly and prevent illness. Avoid steep slopes during thunderstorms to prevent panic and accidents.
Drying sheep during the summer heat is an essential part of management. This involves moving sheep to shaded areas outside the enclosure to cool them down and maintain their health. Rushing them back into the pen immediately after grazing can cause overheating and digestive issues. Avoid bringing the flock into the enclosure right after returning home at noon; instead, let them rest in the shade. At night, after grazing, bring the sheep to the yard and wait until midnight to move them into the pen, allowing them to stay overnight in the open. Before morning grazing, drive the sheep out of the enclosure for 1–2 hours to dry them off. Starting in early summer, set up sheep pens with wooden planks for lambing areas and fill the inside with dry soil to keep it clean and ventilated. Many farmers now use two-story barns that are cooler in summer, allowing sheep to be moved directly into the shelter after grazing. If a sheep shows signs of weakness, lack of appetite, or other symptoms, it may be suffering from heat stress. In such cases, allow the sheep to rest and dry overnight, and treat any sick animals promptly.
