Abstract
A conceptual model of lead metabolism in the body of farm animals with a multi-chamber stomach is presented upon admission to the diet. Input parameters are determined by the daily intake of lead with a diet and factors that modify this process. The model includes three compartments: 1) transport of lead in the gastrointestinal tract (scar, mesh, book, abomasum, small and large intestines); 2) the distribution and accumulation of lead in organs and tissues (liver, kidneys, spleen, heart, lungs, blood, mammary gland, skin, muscle and bone tissue); 3) removal of lead from the body (urine, feces, wool, milk, fetus). The use of the model for estimating the parameters of the transition along the trophic chain “diet – animal – food products”, forecasting and determining the admissible level of lead intake with feed in order to ensure the production of environmentally friendly products in animal husbandry in conditions of pollution of agricultural land is discussed.
