Protein is usually the most expensive food item, which facilitates the growth and repair of body tissues. With the correct use of this special material, costs can be reduced. Protein from animal sources (milk, liver, fish scraps, meat or meat powder) is more effective in enhancing egg growth and production than protein from most vegetable sources. But the ingredients of livestock and poultry feed are not limited to meat, but plants such as wheat, barley, triticale, soybean meal are used. This nutrient is especially necessary for poultry and young livestock. The amount of consumption affects the productivity of their eggs and meat. It should also be noted that excess protein has a forcing effect that may be harmful to poultry of any age. . Protein sources in livestock and poultry feed are divided into two general categories:
o Meat and bone powder: is prepared from the waste of slaughterhouses.
o Blood powder: is prepared from the dried blood of animals.
o Fish meal: is made from fish waste.
o Milk powder: is made from cow's milk powder.
o Eggs: It is used in powder or liquid form.
Fats are an important part of animal diets due to their easy digestion. Fats have high nutritional value and not only act as energy storage but also insulate the body. Fat sources in animal and poultry feed can be from plant and animal sources. Fats are one of the basic components of nutrition, which are important as the main source of energy, transporting fat-soluble vitamins, building cells and hormones, as well as providing flexibility in food for livestock and poultry. Oilseeds are the main source of fat in agricultural feeds. Cotton seed oil, rapeseed oil, sunflower oil, linseed oil and soybean oil can be mentioned as sources of fat in animal feed. In general, the advantages of using fat in livestock and poultry feed can be mentioned as follows:
• Rich source of energy and the main method of increasing the energy of food ration
• Increased growth rates
• Increased feed efficiency
• Decreased feed intake
• Source of Saturated & Unsaturated Fatty acids (Source of Saturated & Unsaturated Fatty acids)
• Reducing feed dust
• Increasing the taste of food
• Increasing the animal's body temperature and maintaining caloric intake, which causes It reduces the stress in the animal.
• It is possible to slow down the feed transfer in the intestine and thus increase the digestibility.
• It may show the effect of "extra calories".
• It is possible be more affordable than other energy sources.
Company engormix America, some concerns that should be raised about fat consumption noted as follows: • Using higher levels of fat may counteract the effects of pelleting.< br>• Measuring metabolizable energy (ME) content can be difficult.
• Potential for rancidity
• Equipment requirements for fat additives must be adequate. (Equipment needs relative to fat additions must be adequate)
• Poor digestibility of saturated fats by the young bird.
• Use of refined fats (Use of Rendered Fats)
