Studying the Influence of Microbial Preparations of the Vetom Series on the Productivity and Quality of Cow-Derived Product

On the 60th day of the experiment, the median of fat content in the milk of cows in experimental groups 1, 3 and 4 was higher by 37.07, 23.03 (P<0.05) and 4.31%, respectively, while in cows of experimental group 2, it was lower by 23.28% than in the counterparts from the reference group (Table 2,...

Description
Summary:	On the 60th day of the experiment, the median of fat content in the milk of cows in experimental groups 1, 3 and 4 was higher by 37.07, 23.03 (P<0.05) and 4.31%, respectively, while in cows of experimental group 2, it was lower by 23.28% than in the counterparts from the reference group (Table 2, Figure 2). [...]fat content in the milk during the period of preparation administration increased when Vetom 1 was used at the dosage of 50 mg/kg, and Vetom 1.23 was used at the dosage of 1.0 and 0.5 pl/kg of the body weight, both during the application of the preparation and 60 days after the use of the preparation was stopped (Figure 2). Since the trend of overall decrease of the fat content in experimental groups 1-3 and 4 was less pronounced than in the reference group (-17.62; -30.30 and +7.26%, compared to -39.27%), one could speak of more positive effect of the schemes used in experimental groups 1-3 on fat content. Over the period of the study, high interquartile fluctuations of fat content in milk were observed in the 2nd experimental group on the 15th day of the experiment (2.28%) and in the 3rd experimental group on the 30th day of the experiment (2.20%). Since the trend of much stronger fluctuation, compared to the rest, was not observed in other periods, one could draw a conclusion that the research results depended on the preparation used, the dosage, and the application scheme. On the 60th day of the experiment the median of the protein content in milk from cows in experimental groups 1-4 was lower by 1.89, 0.79, 11.32, and 5.35%, respectively, than in the counterparts from the reference group. [...]protein concentration increased in milk from cows in experimental groups 1-2, and reduced in the animals in experimental groups 3-4.
