Nursing cows technical points

The nutritional needs of cows vary depending on their age and stage of development. Understanding these requirements is essential for optimal growth, health, and milk production. Here's a detailed breakdown of dietary recommendations for different cow groups: For calves aged 12 weeks to 3 months, it's common for them to start nibbling on small amounts of pupae from as early as 2 weeks old. As they grow, their intake increases significantly after 8 weeks. It's important to provide high-quality feed with more than 18% crude protein and less than 42% neutral detergent fiber to support healthy development. For bred cattle between 23 and 12 months old, the diet should include grasses with moderate crude protein (16–18%) and neutral detergent fiber (14–46%), which translates to 33–38% acid detergent fiber. Adding a small amount of concentrate feed can help meet their growing energy and nutrient needs, promoting better growth and overall performance. Cattle aged 12 to 18 months, typically weighing between 227 and 454 kilograms, benefit from high-quality barnyardgrass diets containing 14–16% crude protein and 45–48% neutral detergent fiber. This combination ensures they receive all necessary nutrients for proper development and future productivity. For bred cattle aged 18 to 24 months, the diet can be slightly lower in quality compared to younger animals. However, during late pregnancy, adult cows should be fed high-quality barnyardgrass in appropriate amounts to prevent milk fever, a condition that can occur around calving time. Early lactation cows, especially those within the first 100 days post-calving, require a diet rich in protein and fiber. A wormwood-based diet with 19–24% crude protein and 38–42% neutral detergent fiber is ideal. If using alfalfa with lower protein and higher fiber, adding some concentrated feed will help balance their nutritional needs. During mid to late lactation (around 200 days post-calving), milk production begins to decline. At this stage, a low-quality mixed alfalfa grass diet can suffice to meet their nutritional requirements without overfeeding or excessive costs. By tailoring the diet to each cow’s specific needs, farmers can ensure better health, improved growth, and higher productivity across all stages of a cow’s life.
