Alfalfa contains a lot of protein, which can meet the nutritional needs of rabbits. But if you feed rabbits with oats, they will get flatulence. No other hay is higher than alfalfa protein. Secondly, the crude fiber content of ladder grass is the highest. Rabbits can eat indefinitely and grind their teeth for digestion. In addition, they can pick fresh bitter vegetables and give them bean sprouts. Celery leaves are coarse fiber, but you can't pick lawn grass. Cinchona grass (that is, plants with milky liquid on their stems) and Huimin dishes eaten by pigs (I don't know the scientific name) basically died after eating for a few days. Please pay attention to the suggestion that the picked grass should be washed and dried before feeding, because there will be eggs and cat and dog excrement on the lawn, which is not very clean.
