The growth of the world population has caused an increase in the demand for food of animal origin, where cattle have become one of the most important species economically speaking, due to the high costs of concentrates, interest has been generated in the search for feeding alternatives. The objective of this work was to determine the behavior of some zoo technical parameters in calves supplemented with different of FES potato-carrot inclusions. Four groups were established with a basic diet of milk and forage, two groups were supplemented with 6 and 9 g/kg/PV of FES-carrot feed, one group with 6 g of balanced concentrate and the control group. The variables evaluated were weight gain, height at the withers and food consumption. The animals of T2 and T3 reached a statistically higher final weight (p <0,05) in relation to the animals of the control group; the highest height at the withers was achieved with the T2, reporting a height of 85 cm. Supplementation with 6 g of FES feed turns out to be a feeding alternative, obtaining better results in zoo technical parameters and being more economical. [ABSTRACT FROM AUTHOR]
