It is a part of the livestock diet that can maximize the production and genetic capacity of the livestock. It is provided to the livestock in a ready and complete form. These feeds should have high energy and protein and low fiber. 2- What are the ingredients of quality concentrate? Concentrate ingredients include types of flour (cotton seed, rapeseed, sunflower, soy...) and grains (barley, corn, wheat, etc.) and minerals (calcium carbonate, zeolite, dicalcium phosphate, etc.) and oil and supplements. These materials have digestible protein and high percentage of metabolizable energy that provide the animal's need for minerals and vitamins at the same time.
3- How to distinguish high-quality concentrate from low-quality concentrate? The best and most reliable way of diagnosis is the analysis of the concentrate through the laboratories that have the approval of the Veterinary Organization and the Ministry of Jihad Agriculture. In the next stage, the animal itself is also considered an important laboratory if all the nutritional standards are met and the environmental conditions are the same.
4- Should we increase the amount of concentrate consumed daily or change the type of concentrate in order to increase livestock production? In order to increase the production, it is necessary to change the type of concentrate and adapt it to the conditions of the animal. In dairy and fattening animals, the amount of protein and energy required in the diet is different in different periods, for example, in dairy animals, in the period before calving, after calving and peak production. Livestock needs a concentrate with high protein and energy content, which, if the need is met, in addition to solving the problems of hard birth and preventing shiroctosis fever, etc., we will face an increase in milk production during the lactation period.
