Carbohydrates are a vital source of energy for animals, providing glucose to fuel bodily cells. While they are not an essential macronutrient, they offer immediate energy, reducing the need for the body to convert protein to glucose, which requires more energy. Carbohydrates are metabolized and utilized by the body, supporting digestive function and overall health. They are especially important for specific tissues, such as the brain, and certain cell types, like red blood cells, which rely on glucose for energy. In addition, carbohydrates are crucial for the manufacturing of commercial pet food, and their inclusion can enhance the overall nutritional value of the product.

What You'll Learn
Carbohydrates provide energy for bodily functions
Carbohydrates are one of the main nutrients that are utilised in the animal body. They are needed to provide energy for bodily functions. Carbohydrates can be metabolised, and simple carbohydrates are converted and used as energy. This energy is needed for bodily functions such as heart work, protein synthesis, and fat synthesis.
Monosaccharides, the simplest structure of carbohydrates, have a molecule of sugar and break down easily. They are a quick-releasing energy source. Glucose, a simple carbohydrate, is converted and used as energy in the animal body. When this is the case, other macronutrients are used for other jobs such as the growth and repair of tissues.
In the case of a deficiency of carbohydrates, the body can convert protein to glucose. However, this process requires more energy than simply using carbohydrates as an energy source. The body must break down amino acids, the building blocks of protein, into smaller protein chains, and then into glucose. This process takes energy away from other vital bodily functions.
In cows, most ingested carbohydrates go straight to the small intestine before being broken down. Monosaccharides and disaccharides are connected by rumen microorganisms and used as an energy supply. In dairy cows, the type of carbohydrate fed affects milk fat and milk yield. The primary nutrients that ruminal degradation provides to cattle are volatile fatty acids (VFAs) and microbial protein. VFAs can provide up to 70% of the energy required by cattle.
In dogs and cats, carbohydrates provide a valuable source of glucose in pet foods. While dogs and cats do not have a dietary requirement for carbohydrates, they can digest and benefit from them. Dogs, in particular, have evolved to be able to digest carbohydrates during their time with humans.

Carbohydrates are not essential, but they are beneficial
Carbohydrates are indeed not essential for animals, but they are beneficial. While animals can survive without carbohydrates, they provide a valuable source of energy. Carbohydrates are one of the main nutrients utilised in an animal's body, and they can be quickly metabolised.
Simple carbohydrates, such as glucose, are converted into energy. This energy is used for bodily functions and to fuel bodily cells. Glucose is especially important for specific tissues, such as the brain, and certain cell types, like red blood cells, which rely on it for energy. Carbohydrates also support digestive function and overall health.
In addition, carbohydrates can be beneficial for gut health. Fibre, a type of carbohydrate, contains enzymes that mammals cannot digest. However, these enzymes are used by bacteria in the gastrointestinal tract, which is necessary for a healthy gut.
For pets, carbohydrates are especially important for energy and overall health. Dogs, for example, have evolved to digest carbohydrates efficiently during their domestication alongside humans. Cats, despite being carnivores, can also digest carbohydrates for energy. Obesity in pets is often blamed on carbohydrates, but this is a misconception. Weight gain in pets is usually the result of consuming too many calories and not burning enough, regardless of the nutrient source.
Therefore, while carbohydrates are not essential for animals, they are beneficial for energy, digestive health, and overall bodily functions.

Carbohydrates are important for digestive health
Simple carbohydrates, such as glucose, are quickly converted and used as energy. This allows other macronutrients to be used for growth and repair of tissues. For example, when there is a lack of carbohydrates, the body can convert protein to glucose, but this is a complex process that requires more energy. Carbohydrates, therefore, support digestive health by providing immediate energy and reducing the need for complex processes.
The body breaks down carbohydrates into glucose through various processes. In animals with a rumen, such as cows, ingested carbohydrates are broken down by microorganisms in the rumen and then used as an energy supply. In other animals, such as chickens, starch is digested in the small intestine with the help of pancreatic alpha-amylase. In all animals, the small intestine and pancreas produce enzymes that enable the digestion of starches and sugars into glucose.
The type of carbohydrates in an animal's diet is important for digestive health. Simple carbohydrates are quickly fermented and provide energy, while complex carbohydrates take longer to digest. A high-fiber diet, for example, can affect the type of fatty acids produced, with a high-fiber diet favoring acetate and a high-concentrate diet favoring propionic acid. The type of carbohydrate fed to dairy cows, in particular, can highly impact their milk fat and milk yield.
Overall, carbohydrates are important for digestive health as they provide a valuable source of energy, support bodily functions, and can be easily converted into glucose. The type of carbohydrates and the way they are blended with other nutrients are key factors in an animal's diet.

Carbohydrates are used to make commercial pet food
Carbohydrates are a necessary component of pet food. Cereal grains are often used because of their low cost, high nutritional value, and wide availability. Carbohydrates are functional ingredients for pet food processing. They are one of the main nutrients that are utilised in an animal's body. They can be metabolised and provide energy.
Starch is an important dietary source of glucose, which is a simple carbohydrate. Glucose is used for energy in the animal's body. When macronutrients are converted to protein, they are used for other jobs, such as the growth and repair of tissues. Carbohydrates also play a vital role in manufacturing commercial pet food. The gelatinisation of starch granules benefits both the extrusion process for dry and semi-moist products and the retort process for wet products.
While carbohydrates are not considered essential, starches supply energy over an extended period, helping to give animals the energy needed to support basic functions between meals. By utilising fats and carbohydrates for energy, protein is spared to support other bodily functions, such as building, maintaining, and repairing cells and body tissues, as well as maintaining a healthy coat.
Dogs and cats can digest and benefit from carbohydrates. While cats are carnivores, they can efficiently digest and metabolise properly processed starches and complex carbohydrates. Cats can digest starches at approximately 93% efficiency when they are properly extruded. Dogs, on the other hand, evolved during their domestication to become adept at digesting carbohydrates.
However, it is important to note that weight gain in pets is often blamed on carbohydrates in the food. While this is a misconception, it is crucial for pet owners to provide their pets with sufficient exercise and closely monitor their calorie intake, weight, and body condition.

Carbohydrates are one of the main nutrients utilised by animals
Carbohydrates are composed of simple sugars, known as mono-, di-, and oligosaccharides. These sugars are quickly fermented, yielding microbial cells, organic acids, gas, and microbial glycogen. In cows, most ingested carbohydrates go directly to the small intestine before being broken down, and in lions, carbohydrates are broken down by pancreatic alpha-amylase in the small intestine. This process also occurs in other animals, including chickens and humans, where salivary amylase breaks down starch into maltose.
Monosaccharides, the simplest form of carbohydrates, include galactose, glucose, and fructose. They have a basic chemical structure of C6H12O6, with 3 to 7 carbon atoms, and a white, crystalline appearance. These simple carbohydrates are easily metabolised and converted into energy, providing quick-releasing energy for animals.
Glucose, derived from carbohydrates, is vital for energy production in animals. It fuels bodily cells and supports essential functions, including heart function, protein synthesis, and fat synthesis. The oxidation of glucose allows animals to recover the chemical bond energy of glucose in a usable form.
Additionally, non-digestible carbohydrates, such as fibre, play a crucial role in maintaining gut health. While animals like dogs and cats do not have specific carbohydrate requirements, they benefit from the energy and digestive support that carbohydrates offer. Carbohydrates are a valuable source of glucose in pet foods, and their inclusion can enhance overall health and energy levels.
