The first industrialized foods that showed up in Brazil in the 1970s were the products that are currently referred to as “combat line”. Although they’ve been around for a long tim, they conserve the same characteristics: minimal nutritional levels, low cost, low quality ingredients, variable formula (which means that in the absence of one of the ingredients, or the rise in its price, the manufacturers replace it with another of similar quality, which can cause diarrhea, in addition to the bad digestion of the food) and vegetable sources of protein and fat.

The combat line is commercialized mainly in non-specialized channels (supermarkets for example) at extremely accessible prices. However, they are foods of a low nutritional density, making the animal ingest larger quantities to feel satisfied and get the minimal needed ingredients out of the product, which presents a disadvantageous cost-benefit ratio.

In the 1980s, more elaborate products appeared, known as the Premium type, with higher nutritional levels than the combat variety, more palatable (tastier) and with a bit more rigor in quality control and raw materials. Nevertheless, it followed the same nutritional philosophy of the variable formula and was made up mostly of ingredients of vegetable origin. In addition, differentials such as colorants and artificial "culinary" flavorings were introduced besides formats that aimed to be pleasing only to the eyes of the owners of cats and dogs, without adding any nutritional value to the food.

The Super Premium foods date from the 1990s, and PremieRpet® was a pioneer in launching this line in Brazil. It presents the most recent nutritional advances and modern production technology adding high quality ingredients, in addition t nutritional supplements which offer more quality of life to the animal in the long term, and consequently more longevity. They are mainly sold through the specialized channels (veterinary clinics, pet shops and pet food stores), present high nutritional value and focus on the quality of ingredients and performance of animals in the diverse stages of life. The Super Premium foods present a better cost-benefit ratio because they provide high digestibility and energetic density allowing for high nutritional quality, besides a smaller ingestion of food. In addition to this, they reduce the risk of nutritional disease throughout the lives of dogs and cats.

Super Premium foods present the highest levels of nutrition, covering not only the minimum nutritional requirements set forth by the Conselho de Nutrição Animal do NRC (National Research Council) and the AAFCO, but also the most demanding physiological conditions, such as reproduction, training and the recovery of pathological conditions of dogs and cats. The optimal nutritional levels must be balanced between the minimum and maximum nutritional levels as presented by the AAFCO (Association of American Feed Control Officials); These levels are determined by live research, that seek optimal coat conditions, muscle development and above all, optimal performance in reproduction and the immune system.
