EFFECT OF ADSORBENT AND PREPARATION LECITHIN ON RUMEN METABOLISM AND LIVER CHEMISTRY OF FATTENING BULLS WHEN VIOLATING THE ECOLOGY OF THEIR NUTRITION
As preparations for heavy metal detox, adsorbents, which have a synergistic effect with a large list of biologically active compounds are used. At the same time, phospholipids affect the rumen metabolism and liver function of ruminants. The aim of the study was to determine the effect of adsorbent Toxisorb and preparation Lecithin on the rumen metabolism and liver chemistry of fattening bulls with excessive content of heavy metals in diets. The research objects were Swiss young, which at the age of 6 months by the analogue scale was divided into 4 groups of 10 heads each. According to the research results, it was found that when feeding adsorbent Toxisorb at a dose of 1,25 kg/t and phospholipid Lecithin at a dose of 10 g/100 kg live weight as part of diets with increased heavy metal level, the in fattening bulls of the third experimental group, the processes of rumen metabolism were optimized. Young of the third experimental group had in the content of their proventriculus the highest level of molar content of volatile fatty acid, which in this indicator were significantly (P>0,95) in advance of their control counterparts by 3,20 mmol /100 ml, first due to the higher level of propionic acid - by 4,20%. Due to the synergistic effect of joint supplements in diets with high levels of heavy metal salts, the most effective detoxification of these ecotoxicants was observed. Therefore, versus the control counterparts in fattening bulls of the third experimental group, the average liver samples contained less cadmium by 2,69 times (P>0,95), zinc - by 2,07 times (P>0,95) and lead - by 2,75 times (P>0,95). The concentration of these elements in the liver of young cattle of the third experimental group in no case exceeded the MPC.
