Two experiments were carried out at the Agricultural institute, Shumen- a scientific economic one and a physiological one for digestibility of nutrients. The first experiment was carried out with a total number of 30 pigs from the Danube white breed, divided into two groups with 15 pigs in each. The experiment has started in 39,786-39,923 kg live weight and has ended in 104.643-105.308 kg live weight. The physiological experiment was carried out with 6 fattening barrows with 63.000-63.300 kg live weight, divided into 2 groups of 3 barrows each. The aim of the present study was to establish the effect from the use of CARBOVET in the compound feed on the productivity and digestibility in fattening pigs. The addition of CARBOVET (in dose 3 kg/t and 1.5 kg/t from 39 to 58 kg and from 58 kg to 105 kg live weight respectively) in the compound feed for Danube white pigs didn’t influence on the growth intensity and the feed conversion ratio. The addition of CARBOVET in the compound feed for fattening pigs didn’t affect on the digestibility of nutrients.
