CUCURBITAESEMENISOLEUM ENRICHED EFFECT WITH HIGHLY DISPERSION PARTICLES OF MANGANES ON THE DIGESTIBILITY OF DRY SUBSTANCE AND MICROBIOLOGICAL PROCESSES IN ANIMAL RUMEN
The study examined the effect of pumpkin seed oil together with finely divided manganese particles on digestibility and microbiological processes in the rumen when red steppe gobies are included in the main diet. The experimental part of the research was carried out at the production base of the Pokrovsky Agricultural College - a branch of the Orenburg State Agrarian University at 4 groups of fistulated bulls (n=3) - a control and three experimental ones. The difference in the feeding of experimental bulls from the control was that in the main diet they received pumpkin seed oil (Cucurbitae semenis oleum) mixed with highly dispersed particles (UDF) Mn, respectively, 310.4 mg, 307.2, and 304.0 mg per head per day. An increase in the number of VFAs and calves from the experimental groups was found to be increased by 2.56%; 5.59 and 3.75% compared to с control. Feeding various doses of pumpkin seed oil with VDF manganese to young cattle contributed to an increase in the content of microbial nitrogen in comparison with the control group, respectively, by 1.5 mmol / L or 0.77%; 6.0 mmol / L or 3.07% and 3.2 mmol / L or 1.64%. The introduction of Cucurbitae semenis oleum together with с VDF manganese at a dose of 307.2 mg / goal contributed to an increase in the content of total nitrogen in the scar fluid by 4.19%; 3.48 and 1.97%, digestibility of dry feed by 9.77%, 5.93 and 1.61% compared to the remaining groups. The number of bacteria and the cicatricial excreta taken from animals of the experimental group II was higher by 0.142 g (50.0%) and 0.025 g (16.44%) (P≤0.05); 0.065 g (22.88%) and 0.014 g (9.21%) (P≤0.05); 0.028 g (9.85%) and 0.011 g (7.23%) (P≤0.05) in comparison with analogues from the control, I and III groups.
