Toxicological safety assessment of ZeolFat energy feed additive

Abstract

Development of inexpensive and environmentally friendly feed additives based on waste from the food industry and expired products as energy sources for animals is of current relevance and high demand. The study aimed to test the toxicological safety of ZeolFat energy feed additive (EFA) on laboratory animals. The tests on white rats showed that ZeolFat EFA is a low-toxic feed product with no cumulative properties revealed. The animals exhibited satisfactory physical state and a good appetite during experimental feeding. They were active, and their response to external stimuli remained similar to that before EFA introduction. ZeolFat EFA had a stimulating effect on carbohydrate and lipid, and mineral metabolism in rats, thereby ensuring a high increase in their live weight.

“…Feed additives are nonnutritive products added to the basic feed mix to enhance productive function and growth, preserve feeds, increase the efficiency of feed utilization, or benefit metabolism and animal health [ 1 , 2 ]. Numerous studies and individual experiences gained by livestock owners have shown that the comprehensive feeding of animals, especially for high-yielding cattle, is impossible without highly effective feed additives such as antibiotics [ 3 , 4 ]. The beneficial effect of antibiotics as a growth stimulant was discovered in the 1940s [ 1 , 2 ].…”
