I looked on my bag of TOP pellets, and the ingredients are not exactly the same, but very close. I am looking at an older bag of TOP pellets because I buy the 25 lb bags and then repackage them into the smaller bags I have from earlier years, freeze them, and take out only smaller quantities at a time. I can look at a newer bag of TOP pellets soon - if I remember to.
Perhaps the ingredients are slightly different on purpose even if they are manufactured by the same company. I think sometimes businesses do that. They might package under their own label and then also as Kroger or some store brand, and they might change up the ingredients slightly, or they might be exactly the same.
At any rate, your list of ingredients and the processing technique look good to me. I would say they are very similar to TOP pellets, if not exactly the same.
TOP pellets are my number one preferred pellets for any birds I can get to eat them. (My rosey bourkes just doesn't seem to be able to break them up to eat them, but all my other birds do.) My daughter's parrotlet eats TOP pellets just fine. Even though he weighs less than the bourkes, his beak is stronger. He loves them.
I feed everyone except Stanley (bourkes) mostly TOP pellets, with Harrison's rotatoed often. I would estimate, as far as pellet consumption, that they eat about 60% TOP pellets, 30% Harrison's pellets, and 9% Zupreem naturals. (I will throw in an occasional day of the Zupreem fruity pellets for some of them, as a treat, because they love them, but I liken it to feeding them Fruit Loops for the day. It won't kill them as an occasional treat, but it sure hypes them up. I WON'T handle the grey or the senegal on the days when they get their fruity treats, because they WILL bite me if I do. Shira, the green cheek, is also more nippy if she has had them, but she doesn't really like them, anyway, and her nips are not so bad that I won't take a chance on holding her.) My children's birds, the maximilian pionus, rosey bourkes, and linnie, seem to be able to handle the fruity pellets on occasion without becoming nippy. I have no idea how that will play out with the newer birds - the parrotlet, quaker, and princess of wales. They all weaned in the bird store onto the fruity Zupreem, but all preferred the natural Zupreem to the fruity stuff, anyway.
OK - so that stuff you probably didn't need to read. Back to your question about these pellets. They look like a repackaged type of TOP pellets to me, given the ingredients list they sent you and the fact that someone on here said that is what they are. Their ingredients are only slightly different from the ingredients listed on the bag of TOP pellets I have here. My parrotlet loves TOP pellets and is VERY sweet. I wouldn't see any reason not to try these pellets if you want to.
One thing that needs to be done when you feed TOP pellets is to ensure that your bird has some exposure to natural sunlight whenever possible. Taking the bird outside for a few minutes daily in a carrier that allows exposure to sunlight is an easy way to do that. You can also try full spectrum lighting. It is ok, and even preferred, to put the bird in shade if it is too hot in the direct sunlight.
In the winter, when I can't expose my birds to sunlight, I do feed a higher percentage of Harrison's pellets than I do during the times of year when I can take the birds outside some.
I am curious now as to whether or not these are exactly the same formulation as TOPs or not, and whether or not they are manufactured by the same people.
