摘要

Feed efficiency is a measure of how well cows convert the nutrients they eat into products: milk, muscle, fat, and calves. On the most basic level, it gives an idea of how closely a ration meets an animal's nutrient requirements, and of the relative demands of maintenance and production. In the larger picture, feed efficiency speaks to ration, management and environmental factors that affect feed digestibility and animal maintenance requirements. By and large, for lactating cows, if feed doesn't makemilk, it makes manure. Evaluation of how well a herd converts feed dry matter and protein into salable product can be another useful tool for deciding whether it may be possible to get a better return on your feed investment, and if you can decrease the amount of manure nutrients you will have to manage.
