EFFECT OF ADSORBENT AND PHOSPHOLIPID ON METABOLIC PECULIARITIES IN THE DIGESTIVE TRACT OF FATTENING BULL-CALVES
Important in improving the consumer properties of local meat products when fattening bull-calves in RNO-Alania is the rational use of new domestic preparations with high sorption capabilities. In addition, these new-generation adsorbents show a synergistic effect on metabolic processes and the elimination of various toxins with a large set of feed biologically active additives (BAA). They can provide a special effect with a number of feed phospholipid complexes. The aim of the research is to identify the efficient impact of sorbent Toxisorb and phospholipid lecithin on the digestive processes of fattening bull-calves when using them in diets with heavy metal excess. Based on the experimental data, we recommend introducing adsorbent Toxisorb in the amount of 1.25 kg/t and lecithin in the amount of 10 g/100 kg into the diets with an increased level of HM salts for fattening bull-calves to improve their biological and productive characteristics. The bull-calves of the third experimental group compared to the control counterparts also had an advantage in the results of the absolute and average daily body weight gain by 11.16% (P<0.05). Due to the intensification of hydrolysis process of complex organic compounds in feeds under the impact of fed dietary supplements, , the young animals of the third experimental group compared to the control group digested crude protein by 3.32 % (P<0.05) better, nitrogen free extractives - by 3.33% (P<0.05), crude fiber - by 3.24% (P<0.05), and thanks to this, dry matter - by 3.36% (P<0.05) and organic matter - by 3.45% (P<0.05). This is confirmed by an increase in the daily nitrogen deposition in the diet of young animals of the best experimental group by 6.34 g (P<0.05).
