Nursing cows technical points

The nutritional requirements of cows vary depending on their age and stage of development. Understanding these needs is essential for ensuring optimal health, growth, and milk production. Here's a detailed breakdown of dietary recommendations for different groups of cattle: For calves aged 2 to 12 weeks, their diet should gradually introduce small amounts of pupae starting at 2 weeks old. By the time they reach 8 weeks, their intake increases significantly. It’s important that the feed contains more than 18% crude protein and less than 42% neutral detergent fiber (NDF) to support healthy growth. Calves between 3 and 12 months of age require a balanced diet with a moderate level of crude protein. Feeding them grasses with 16–18% crude protein and 14–46% NDF (33–38% acid detergent fiber) can be beneficial. Adding a small amount of concentrated feed helps meet their growing energy and nutrient needs effectively. Cows aged 12 to 18 months, which typically weigh between 227–454 kg, benefit from high-quality barnyardgrass diets containing 14–16% crude protein and 45–48% NDF. These diets ensure they receive all necessary nutrients for proper development and future productivity. For cows between 18 and 24 months of age, the diet can be slightly lower in quality compared to younger cattle. However, adult cows in late pregnancy should be given high-quality barnyardgrass in appropriate amounts to prevent milk fever during calving. During early lactation (the first 100 days post-calving), cows need higher levels of refined protein. A diet with 19–24% crude protein and 38–42% NDF is recommended. If using alfalfa with lower protein and higher fiber, it’s advisable to supplement with some concentrated feed to maintain milk yield and cow health. In 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 be used to meet the cow’s nutritional needs without overfeeding. Proper feeding strategies tailored to each stage of a cow's life are crucial for maintaining performance, reproductive success, and overall well-being. Always monitor the cow’s condition and adjust the diet accordingly for best results.
