Winter brings unique challenges for livestock, particularly for bulls, which play a crucial role in breeding. Karla Wilke, a cow-calf/stocker specialist with Nebraska Extension, stresses the importance of including bulls in winter management plans. As bulls constitute a major investment in the herd, with natural service being the primary breeding method, their year-round maintenance is essential.
Bulls, often housed in smaller groups, are more exposed to winter elements compared to cows. Protection from harsh weather is critical to prevent issues like frostbite on testicles, which can lead to decreased semen production and quality. Wilke suggests using windbreaks and bedding such as lower quality feed bales or corn stalk residue to provide necessary shelter and protection.
Injuries during winter, for example from slipping on ice, can also be detrimental if a bull doesn't recover in time for the breeding season. This could result in significant losses, requiring the bull to be sold or culled. Maintaining a good body condition score, ideally between five and six, is crucial for semen quality. Young bulls, particularly vulnerable to weight loss and nutritional deficiencies, require close monitoring.
The age of the bulls also affects breeding strategies. Young bulls can manage 10-15 cows, while mature ones can handle 25-30. Mixing different ages can lead to dominance issues, potentially causing injuries. Regular breeding soundness exams are crucial for all bulls to ensure continued breeding efficiency.
This is especially important for dominant bulls, as their inability to breed effectively can impact the entire herd's breeding cycle.
Proper winter management and health care of bulls are not just about maintaining the current stock but ensuring the future generation's success in the herd. This underscores the need for careful, year-round attention to these valuable animals in the livestock industry.
