Sugar graze and maize what best for silage making for dairy cows?

Maize is generally considered the best option for silage making for dairy cows. Maize silage has a higher energy content and is more digestible for cows compared to sugar graze silage. Additionally, maize silage has a higher dry matter content, which can result in better fermentation and preservation of nutrients. However, sugar graze can also be a good option for silage making, especially if it is harvested at the right stage of maturity and properly ensiled. Ultimately, the best choice will depend on factors such as availability, cost, and nutritional requirements of the dairy cows.
