The importance of fat in animal production:
1. Fat is an important form of energy storage for animals, and the main component of cell membranes, helping to maintain the complete form of cells;
2. Fat has a higher net energy and is an important source of energy for animals. The energy value of fat is about 2.25 times that of carbohydrates and protein;
3. Fat provides essential fatty acids for livestock and poultry production, and fat-soluble nutrients in feed such as pigments, vitamins A, D, E, K, etc. must be dissolved in fat before they can be effectively absorbed by the body.
The digestion and absorption process of fat in animals:
Factors affecting the application of fat in animal production:
1. The transportation of fat in the body and the enzymatic reaction of lipase to decompose fat are carried out in the water phase. The hydrophobicity of fat is the primary factor affecting the effect of fat application;
2. Animal's physiological structure, life and production environment;
1) Insufficient bile salt secretion in young animals;
2) The length of the digestive tract of animals of different species is quite different;
3) The animal is in a special stress state, and the concentration of its own bile acid and its salt is reduced.
3. Types of fats, such as saturated fatty acids are more difficult to be used by animals than unsaturated fatty acids;
4. The difference in energy value between different sources of the same fat and different batches;
5. The amount of fat added in feed affects the application effect of fat in animal production.
Effective ways to improve the application effect of fat in animal production
※Surfactants with hydrophilic groups (hydroxyl groups) and hydrophobic groups (hydrocarbon long bonds);
※Reduce the interfacial tension of the two phases, which is beneficial to the formation of spherical chylomicrons.
