Securing high-quality pet food is now a growing concern for both pet owners and manufacturers alike. Between 2013 and 2018, nearly 7 million domestic animals were registered in Brazil, according to data from IBGE and Instituto Pet Brasil. This report also highlighted a clear preference for dogs, with over 54 million canines spread across the country. However, the most significant increase during this period was seen in the cat population, which reached more than 23 million by 2018.
These impressive figures reflect the expanding domestic animal population in Brazil and fuel the growth of the pet products industry, which contributed more than $9 billion USD to the economy in 2018 alone. Of this, over $4 billion was spent exclusively on pet food!
This presents a substantial opportunity for pet food manufacturers to tap into this lucrative market. However, simply offering products isn’t enough; it's equally important to ensure these products meet the nutritional needs of our furry companions. Consumers are increasingly willing to invest more in premium pet food that supports their pets' health and well-being.
To create effective pet food that contributes to the health and happiness of dogs and cats, meticulous care is essential. Manufacturers must understand the unique nutritional requirements of each species and select the best ingredients to ensure a balanced diet. Options range from various proteins like beef, chicken, and fish, to grains, vegetables, and essential vitamins and minerals.
Let’s delve deeper into the specific nutritional needs of dogs and cats and how these considerations shape the formulation of pet food.
### Dogs’ Nutritional Requirements
Like all domestic animals, dogs require a balanced diet to thrive. Here’s a breakdown of the key components:
#### Proteins:
Proteins play a critical role in building muscle tissue, aiding in substance transport, facilitating organ communication, and bolstering the immune system. These can be sourced from either plant or animal origins, with animal-based proteins being particularly valuable due to their high biological value.
Puppies, needing to grow, require a diet rich in proteins. Conversely, older dogs often experience muscle loss, necessitating additional protein intake. For instance, puppies weighing up to 5 kg require approximately 56g of protein daily, whereas adult dogs of around 15 kg need about 25g. Senior dogs may require even more protein, around 75g per 1000 kcal, according to the National Research Council (NRC).
#### Fats:
Fats are vital for maintaining healthy skin and coat, supporting brain and vision development, and ensuring proper cellular structure. Puppies deprived of sufficient fats may suffer from dry, coarse fur and heightened vulnerability to infections. The NRC recommends that dogs up to 15 kg consume about 14g of fats daily.
Senior dogs, whose metabolisms are less efficient, benefit from reduced fat and calorie intake to prevent obesity—a common issue in this age group. Animal-based oils, such as poultry or pig fat derived from fresh raw materials, are excellent lipid sources. They are highly digestible and palatable, providing essential fatty acids crucial for pet development.
#### Carbohydrates:
Carbohydrates serve as the primary energy source in dog food. Active adult dogs weighing around 20 kg require approximately 1353 kcal daily, while senior dogs of the same weight need about 1093 kcal.
#### Fibers:
Fiber ensures proper intestinal function, particularly beneficial for dogs prone to constipation. Adult dogs can typically consume up to 50% of their diet in carbohydrates, including 2.5 to 4.5% fiber, with a minimum of 5.5% fats and 10% proteins.
#### Vitamins:
Vitamins play a pivotal role in health, sight, skin condition, and antioxidant activity. Essential vitamins include A (379 µg), D (3.4 µg), E (8 mg), and thiamine (0.56 mg). Deficiencies in these can lead to various health issues, from skeletal muscle ruptures to neurological abnormalities.
#### Minerals:
Minerals are integral to metabolic reactions, nerve impulses, muscle contractions, and bone and tooth health. Calcium (1.0 g) and phosphorus (0.75 g) are crucial for strong bones and teeth, while other minerals like magnesium, potassium, and sodium are vital for nerve transmission and muscle function.
### Cats’ Nutritional Needs
Cats, being obligate carnivores, rely heavily on animal-based nutrients. Their ideal diet should include:
#### Proteins:
Proteins supply essential amino acids for antibody synthesis, enzyme regulation, hormone production, and tissue maintenance. Animal proteins like poultry, beef, and fish are more digestible and complete, providing all necessary amino acids.
Taurine, an essential amino acid for cats, helps prevent eye and heart diseases. Kittens need about 10g of protein daily, while adult cats require 12.5g.
#### Fats:
Fats contribute to cell integrity and metabolic regulation, enhancing the appeal of food. Essential fatty acids, particularly omega-3, are vital for feline health.
#### Carbohydrates:
Cats do not require dietary carbohydrates, obtaining energy from proteins and fats.
#### Minerals and Vitamins:
Cats need specific minerals and vitamins for optimal physiological functions.
### Enhancing Pet Food with Animal Meals
Given the reliance on animal-based nutrients, selecting high-quality raw materials is paramount. Ingredients such as poultry meal, pork crackling meal, and feather meal offer excellent nutritional benefits. Poultry meal, for example, provides high digestibility and essential amino acids, while pork crackling meal offers a rich protein source with excellent palatability. Feather meal, despite its high protein content, must be carefully sourced to avoid anti-nutritional factors.
In conclusion, prioritizing the health and welfare of pets is non-negotiable. By understanding the nuances of these ingredients and sourcing them responsibly, manufacturers can deliver nutritious, palatable pet food that fosters a long, healthy life for beloved companions.
