TMR and vanda are two types of animal feed for dairy farming. TMR is a mix of different ingredients, such as forages, grains, oilseeds, minerals, vitamins, and additives. Vanda is a concentrated feed made from grains, oilseeds, minerals, and vitamins. Both TMR and vanda have pros and cons for animal nutrition and health. TMR and vanda can improve milk production and fattening by providing a balanced diet and a high-energy and high-protein supplement for cows. However, TMR and vanda can also be expensive, require special equipment, and cause acidosis or digestive problems. TMR and vanda should be used based on the needs and preferences of the animals and the farmers. TMR and vanda can also be combined to optimize the feed efficiency and performance of the cows. The best ratio and composition of TMR and vanda depend on the type, breed, age, weight, and production level of the cows.
