The composition of the intestinal microflora of rats with experimental antibiotic-associated dysbiosis and after its correction with a biological product based on lactic acid and propionic acid microorganisms was studied. The results obtained indicate the normalization of the number of microorganisms when using the suspension form of the drug and make it possible to recommend its use in clinical practice for the correction of intestinal microflora disorders in animals.

В статье приводятся результаты разработки технологии получения биоконцентрата на основе многоштаммового консорциума молочнокислых и пропионовокислых бактерий, который может использоваться для силосования зеленых кормов. Установлены параметры ферментации, стадии концентрирования, дана качественная характеристика готового продукта. The article presents the results of the development of the technology of producing bioconcentrate on the basis of multistrain consortium of lactic acid and propionic acid bacteria which can be used for ensilaging green forages. The fermentation parameters, concentration stages, and qualitative characteristics of the finished product are established.

Проведена сравнительная оценка эффективности влияния различных биологических препаратов при консервировании провяленной зеленой массы люцерны, отечественного так и зарубежного производства в лабораторных условиях. По результатам лабораторных исследований было установлено положительное влияние биологических препаратов ФербакСил и Бонсилаж Форте, которые стимулировали в фитомассе молочнокислое брожение, что в свою очередь положительно отразилось на сохранности обменной энергии (8,9 МДж) и сырого протеина (21,1 ), показатели которых были выше контроля на 3,45 и 0,9 . Максимальное кислотообразование в консервируемой массе выявлено при применении импортного препарата Бонсилаж Форте, где показатель суммы органических кислот был наивысшим и составил 3,66 абс. , или выше контрольного показателя на 0,33 абс. , соответственно. При изучении физиологических групп микробиоты готовых сенажей, в консервировании которых использовали биологические препараты, выявлено повышенное содержание молочнокислых и пропионовокислых бактерий. Максимальное содержание первых было установлено при применении препарата ФербакСил 58,8106 КОЕ/г, последних при применении Бонсилаж Форте 7,2106 КОЕ/г, концентрация которых была выше контроля на 3,3 и 2,4 раза. Расчет экономической эффективности показал, что использование препарата Бонсилаж Форте максимально увеличивает себестоимость готового сенажа по сравнению с контролем на 13,0 (1185 руб./т). Применение отечественного препарата ФербакСил способствовал минимальному увеличению себестоимости готового корма 1063 руб/т, стоимость которого была ниже контроля на 1,2 .The efficacy of two biological preparations was evaluated for haylage preparation from dried alfalpha green mass under laboratory conditions. It was shown that biopreparations FerbacSil and Bonehaylage Forte, stimulating lactic acid fermentation in green mass, improved quality of the haylage by preserving exchange energy (8,9 MJ), raw protein (21,1 ), which were higher than those in control by 3,45 and 0,9 , respectively. Maximal acid production in haylage mass was detected after application of Bonehaylage Forte reaching 3,66 absolute , so 0,33 abs. higher than in the control. Microbial associations developed in green mass were represented by lactic acid bacteria and propionic acid bacteria. Application of FerbacSil resulted in increase of by lactic acid bacteria population which reached 58,8106 CFU per gram of green mass. Propionic acid bacteria were proliferating to 7,2106 CFU per gram when Bonehaylage Forte was used as a silaging starter. These value were 3,3 and 2,4 higher, respectively, than in control variant. Calculation of profitability showed that Bonehaylage Forte application increase selfcost by 13 when compared with control and is as high as 1185 roubles per ton of haylage. Using Russian domestic biopreparation FerbacSil resulted in moderate 1,2 of increase of selfcost giving final 1063 roubles per ton, which is 1,2 lower than in control.

The significance of fermentation in the large gut of the dog has been investigated. According to the quantities of volatile acids and their relation to body weight, the lower fatty acids do not appear to contribute more than a small portion of the energy requirements of the animal. Evidence is presented to show that the individual acids produced in the large intestine consist largely of acetic and propionic acids and that the amount of butyric present is small. This is the same mixture of acids found where fermentation occurs in the alimentary tract of ruminants, horses, pigs, rabbits and rats. The higher proportion of propionic acid is interesting and suggests that the propionic acid bacteria are normal inhabitants of the large intestine of the dog and possibly of a wide variety of animals.

Growth and survival of four strains of Listeria monocytogenes under acidic conditions were investigated. Tryptic soy broth with yeast extract (TSBYE) was acidified with acetic, citric, hydrochloric, lactic, or propionic acid to pH 4.0–6.0, inoculated with L. monocytogenes and incubated at 30 or 4°C. The minimum test pH at which L. monocytogenes did not grow (inhibitory pH) was determined for each acid. In the pH range tested, this inhibitory pH was 5.0 for propionic acid, 4.5 for acetic and lactic acids, and 4.0 for citric and hydrochloric acids. All four strains gave similar results. Subsequent studies were conducted at 10 and 30°C to determine changes in cell populations in TSBYE adjusted to each inhibitory pH. Initial populations of viable cells (104 CFU/ml) were reduced to <10 CFU/ml within 1–3 weeks at 30°C, whereas at 10°C, L. monocytogenes survived for 11–12 weeks in acetic, citric, or propionic acid-adjusted media and for 6 weeks in media adjusted with hydrochloric or lactic acid. The concentration of undissociated lactic acid was 0.002 M at pH 4.5.
