Method for Improving the Digestibility and Assimilability of Dietary Nutrients in Fattened Bulls

The objective of this study was to determine the effect of the SorbiMix® sorbent on the growth of young cattle fed complete feeds based on locally sourced ingredients (using the Republic of North Ossetia-Alania as an example) with a tolerable level of T-2 toxin.

Materials and Methods. Swiss bulls served as subjects for the study. Twenty six-month-old bulls were divided into two groups (using the analog-pair method) of 10 animals each. The experiment and fattening period for the compared groups lasted 12 months. The feed for both groups included corn, barley, and soybean meal contaminated with T-2 toxin. To ensure the integrity of the experiment, these contaminated ingredients were mixed with other non-contaminated ingredients, ensuring that the mycotoxin content in the feed for the bulls did not exceed the tolerable level of 0.1 mg/kg. The experimental group animals were fed with 20 g of sorbent per animal. Nutrient digestibility coefficients and crude protein digestibility were calculated, and the phosphorus and calcium balance was studied.

Results. When the tested preparation was added to diets with a tolerant level of T-2 toxin, the experimental group bulls, compared to the control group, had higher dry matter digestibility coefficients by 3,11 % (P>0,95) and organic matter digestibility coefficients by 3,06 % (P>0,95). Including the sorbent in the diets during the metabolic experiment's recording period contributed to the average daily nitrogen retention of 41,26 g in the fattened experimental group young animals. In this indicator, the experimental group animals significantly (P>0,95) outperformed the control group by 5,04 g, or 13,91 %. In addition, the bulls in the experimental group also absorbed the macronutrients calcium and phosphorus better.
