In late autumn and early winter, large animals such as cattle, horses, and donkeys are more likely to experience habitual abortion. To prevent this, proper care and management are essential. Here are some key strategies:
1. **Enhance Nutrition**
Pregnant animals require a well-balanced diet to support their health and the development of their offspring. In addition to high-quality forage, it's important to supplement their feed with protein, vitamins, and minerals. Foods like fish meal, blood meal, soybean cake, bone meal, and limestone can be added to meet these nutritional needs. Carbohydrate-rich concentrates such as corn and millet should also be provided in appropriate amounts. This helps avoid malnutrition-related abortions, stillbirths, or congenital abnormalities in newborns.
2. **Improve Feeding and Management Practices**
(1) **Feeding Habits**: Avoid feeding moldy or spoiled feed. Pregnant animals should not graze too late or return too early. They must not eat frosted or dew-covered grass, as this can lead to digestive issues. Provide clean, warm water whenever possible—avoid cold or icy water. After mating, do not allow them to drink immediately, as this may cause discomfort or complications.
(2) **Work and Movement**: During work, avoid overexertion, long distances, heavy loads, sudden turns, or using whips in the cold. Ensure that the ground is not icy or slippery to prevent injuries. Gentle handling is crucial during this period.
(3) **General Management**: Breeding animals should be kept in single-turn or single-pen systems rather than being allowed to roam freely. Prevent overcrowding when entering or exiting enclosures. It’s recommended to lead them for 20–30 minutes in the morning, evening, and at night to maintain their physical condition and reduce stress. Pay close attention to weather changes and ensure they stay warm and dry to avoid cold-related illnesses.
By following these guidelines, farmers can significantly reduce the risk of abortion and improve the overall health of their livestock during the colder months. Regular monitoring and timely adjustments in care are also vital for successful breeding outcomes.
