Does it really matter what brand or food you use. Over the years I've used many different foods line bio-mare, pig pellets, sheep pellets and many types of rodent pellets with very similar breeding results.
When looking at a new food to try I look for 2 main things, protein % and salt content.
A couple of months ago I set up a colony of weaners and have been feeding them on 100% spiral pasta......32% protein, 21% carbohydrate and 2% salt.
So far they are doing well and with a couple having big bellies I'll soon have some early results.
I have thought the same thing, does it really matter? TBH, how much variation is there? Has anyone actually done any controlled studies on the results of different food types? Does a better food actually allow for the rats/mice to produce a bigger litter? If so, how? If anybody has results I would love to read them out of curiosity.
I have bred rats and mice for years and have tried quite a few different types of feeds such as YS, vella's, Gordons etc. I have found only slight variations, but this does need to be weighed up with the relative costs. Ie, Gordons is good, but very expensive, in fact it is more than double the price I pay for my current feed and I would say it is nowhere near double in quality. I also rarely give them anything else to eat, they generally just get pellets. So if you only have success with biomare by supplementing an extra food source then that is added storage and work for more than one food type. I like a food that works purely on its own merit and anything else I give the animals is a bonus.
Will be interested in seeing your results from feeding pasta. How long have the rodents been on it for so far?
