Amtra presented its new line of PRO feeds during the Zoomark 2019: now we obtained them and we’re ready to do a proper analysis. Let’s see what we found out.

Where’s speaking of flake feeds produced thanks to AMTRA‘s thirty-year old experience. They experimented new methodologies as natural as possible, trying to keep the processes with low temperatures.
The three feeds we’re about to present are: Pro Natural, that more than others uses less alterations as possible, Pro Color, which is added with Garlic and Astaxantina in order to improve the coloration and the immune defenses of the fish, and Pro Vegetal which is mainly vegetable.
The composition of the feeds AMTRA Pro Natural, Color and Vegetal F
The three feeds, ratherly different in their basic composition, have the follow macroingredients:
| Pro Natural F | Pro Color F | Pro Vegetal F |
| Worm flour (Tenbrio molitor, Chironomus sp, Lumbricus terrestris, Bombyx mori) | Wheat | Wheat |
| Wheat | Krill flour | Hydrolyzed fish protein |
| Herrings flour | Hydrolyzed fish protein | Brewer’s yeast |
| Hydrolyzed fish protein | Corn | Spirulin |
| Corn starch | Hydrolyzed shrimp protein | Corn starch |
| Potato | Seaweed flour | Herrings flour |
| Salmon oil | Brewer’s yeast | Salmon oil |
| Carob flour | Kelp seaweed | Chlorella seaweed |
| Alga Kelp | Salmon oil | |
| Betaglucan from brewer’s yeast | Garlic | |
| Paprika |
And their interesting nutritional analysis
| Pro Natural F | Pro Color F | Pro Vegetal F | |
| Raw proteins | 42,7% | 44,7% | 46% |
| Raw fats | 5,8% | 8,7% | 5,3% |
| Raw fiber | 1,3% | 0,5% | 0,7% |
| Raw ashes | 7,9% | 8,1% | 2,8% |
| Moist | 6,7% | 7,9% | 6,3% |
| Other | 35,6% | 30,1% | 38,9% |
As you can see from the chart, the feeds are mainly made by proteins (almost the half of the whole), 5% of fats which are 9 in the Color. Being a rather caloric feed it’s better for fish that usually eat smaller fishes or crustaceans; the Natural, with more fats, it’s good also for cold water fish. In Natural and Color the proteins are close to other similar feeds (49,8%), while the fats are the half for Color and in the average for Natural (9,8%), while the fibers are much lower than usual, 0,5 or 1,3 against 1,7. On the other hand Vegetal has an higher number of proteins for a vegetable feed, 46% against the average of 34,5%, the other values are normal, except for the fibers that are poor anyway. The other elements, moist, ashes and others, are very low in the Pro Vegetal and higher in Pro Color and Pro Natural.
The vitamins
Let’s see now the composition of vitamins, trace elements and additives:
| Pro Natural F | Pro Color F | Pro Vegetal F | |
| Vitamin A | 25.000 IU/kg | 24.700 IU/kg | 25.000 IU/kg |
| Vitamin D3 | 1.500 IU/kg | 11.465 IU/kg | 1.500 IU/kg |
| Vitamin E | 100 mg/kg | 120 mg/kg | 100 mg/kg |
| Vitamin C | 450 mg/kg | 79,1 mg/kg | 450 mg/kg |
| L-lysine | 480 mg/kg | ||
| DL-Methionine | 480 mg/kg | ||
| Betaine | 1,9 g/kg | ||
In all the three feeds the Vitamin A is predominant. Vitamin A promotes a an healthly growth, strengthens the view, defends the skin and acts positively on fertility. Notice also the quantity of amino acids in Amtra Pro Vegetal F.
The Amtra Pro feeds at a close view
In order to confront these feeds with the other we analyzed, let’s watch how they present in detail, with our macro 1:1, even if once in water they get wet and assume a different consistency. The attractiveness anyway is good, at least for Amtra Pro Color F that I used in my aquarium, because it’s the most suitable for marine fish.
The cost
The feeds are sold in jars of 50 grams or 250 ml, at 4,20 euro (about 8,4 cents per gram) for the Pro Natural F, 5,20 euro (about 10,4 cents per gram) for the Pro Color F, 4,5 euro for the Pro Vegetal F (about 9 cents per gram).
