I see folks may be switching feeds due to cost increases.
Remember that switching feeds can be stressful to rabbits. Some will like the new feed and some will not.
We would occasionally try another feed but when the flesh condition dropped, we would switch back.
It may not be the fault of the other feed. Any switch in feed is
stressful and can cause some loss of condition. One should probably
switch for 6 months to really test it a new feed.
When you find a feed that your rabbits do well on, stick with it. As
you breed, you are selecting for rabbits that will do well on the feed
you are giving it.
Other considerations are: I can usually buy feed at a feed store that is on my way to work, no extra trips required. If they are out of stock, there are two other dealers within easy driving distance. Purina has the easy to read date code printed on the bottom paper strip, no 10 digit date codes to decipher.
Have a good day!
