Does it contain solid bone like sculls, backbones, ribs, teeth?
It might be nutritionally better but that doesn't mean it's better for the snake, not very mentally stimulating which i think is an important part of keeping reptiles so i wouldn't say happy.
If all people are worried about is nutritional health for there reptiles why not just tube feed them, they get everything they need for it nutritionally.
You have to fined a balance.
I have over 40 snakes feeding on rodents and i've never had to supplement their food.
How do you know you have a complete blend in each sausage? Is there the equivilant amount of fur compared to a similar sized rodent?
I still can't see how they are better, except in price which should not be an issue when it comes to keeping reptiles.
Reptiles are not domestic animals, which means they need to be kept in conditions similar to the wild.
I think they would be a better lizard food than snake, but not as the entire diet.
