[Influence of some factors on the quality of Bulgarian sour milk].
The results obtained with three feeding experiments revealed that combined forages containing biovit-40 are effective in that the antibiotic is not excreted with cow's milk and it does not inhibit the development of lactic acid fermentation. The season of the year associated with the passage of a given type of feed on to another type was found to influence the course of the lactic acid fermentation as follows: --in feeding green mass in the summer period there is a stimulation of the development of Lactobacillus bulgaricum and Str. thermophilus in the milk; -- in feeding greater amounts of succulent forages in the winter, spring, and autumn periods there is a retardation in the development of the same organisms in the milk.
