Arya oil is for special use in poultry and is completely vegetable with a combination of vegetable and chicken oils. Soy, sunflower, and rapeseed oils, all of which contain essential fatty acids (EFAs) such as linoleic acid and oleic acid, are used at different ratios in completely vegetable oils. The digestibility and absorbability of these oils are suitable and ideal for poultry.
Another oil is a combination of vegetable oils and poultry oils. In terms of fatty acid composition, chicken fat is the best source of fat for chicken diets because its fatty acid profile is the same as that of the chicken body. Chicken fat is of high interest in the feed industry due to its high digestibility, stable quality, and good taste. It resolves the problem of Salmonella and other pathogenic microbes as it is heated at 130-140 °C.
Fats, especially fat supplements, are among the feeds that nowadays play a greater role in livestock and poultry diets. The creation of new attitudes on the role of fats in the health of human societies has nowadays led to paying special attention to the use of fats in livestock and poultry as well as their products. Thus, scientists not only do not prohibit people from consuming fat sources, but they strongly recommend the consumption of some types of fat to prevent widespread diseases such as diabetes, obesity, and cancers.
The main property of fat is that it is a very concentrated source of energy, with each gram containing about 9 kcal of energy, while carbohydrates and proteins contain 4 kcal/g of energy. Therefore, fats have about 25.2 times more energy than carbohydrates and proteins. In other words, fats occupy a smaller volume than other substances in feed with the same amount of energy. Therefore, the use of fats in the feed will provide more space to increase the protein level in the feed. Therefore, the main advantage of using fats in the diet is the availability of high-energy and high-protein diets and the ease of diet formulation.
As mentioned above, fats are the best source of EFAs. Linoleic acid is an 18-carbon fatty acid with two double bonds, which accounts for one of the key EFA for poultry. The vital role of this EFA strongly necessitates its supply through the diet.

Reasons for using fats in livestock and poultry diets
- Fats produce more energy than proteins and carbohydrates.
- They are necessary for the absorption of fat-soluble vitamins.
- They reduce dust in the diet.
- They increase the adhesion of feed particles.
- They lubricate the digestive system and cause a better use of micronutrients.
- Fats decelerate the passage of food through the digestive system, thereby providing enough time for the digestion and absorption of other nutrients by digestive enzymes and other microorganisms in the digestive system.
- They increase the synthesis of prostaglandins
- Fats prevent the fragility of cell membranes
- Fats prevent skin lesions and consequently increase the herd’s resistance to diseases
- They prevent testicular atrophy and delayed occurrence of secondary sexual characteristics
- Fats increase production
- These substances increase the fertility rate
- They increase the growth rate
