Обмен веществ и его особенности определяют состояние здоровья свиней, резистентность организма к неблагоприятным факторам внешней среды. Молодняк послеотъемного возраста особенно подвержен заболеваниям желудочно-кишечного тракта, их причиной являются патогенные бактерии. Этими заболеваниями переболевает до 100% поросят. Фактором, от которого зависит развитие патогенной микрофлоры, является рН переваренного в желудке корма. Изучено воздействие кормовой добавки БиоАцидУльтра, разработанной для снижения уровня патогенной микрофлоры в кормах и повышения продуктивности свиней. Действующие вещества БиоАцидУльтра: муравьиная кислота – 14,45–19,55%; формиат аммония – 8,5–11,5%; пропионовая кислота – 11,9–16,1%; пропионат аммония – 5,95–8,05%; молочная кислота – 1,7–2,3%; кремниевая кислота – 17–23%; вермикулит – 12,83–17,37%; диатомит – 8,84–11,96%; дистиллированная вода – до 100%. Опыт был проведён в условиях племзавода Тамбовской области на четырёх группах поросят для выращивания, подобранных по принципу аналогов (порода, возраст 21 день, живая масса), размещённых в помещениях с одинаковыми условиями содержания. Установлено, что кормовая добавка БиоАцидУльтра, добавленная в корм поросятам, позволяет эффективно контролировать диарею при отъёме их от свиноматок и дальнейшем выращивании, а также оказывает положительное влияние на среднесуточный прирост живой массы. Исследования показали, что в кишечнике животных опытных групп преимущественное положение занимают анаэробные бактерии, представители нормальной микрофлоры. Биохимический анализ крови показал, что у животных опытных групп произошло увеличение общего белка, гемоглобина, содержания кальция и фосфора, уменьшилось содержание мочевины. Установлена наиболее эффективная доза подкислителя корма БиоАцидУльтра в рационах молодняка при выращивании: группа поросят, которым скармливали кормовую добавку в дозе 3 кг/т комбикорма, показала лучшие результаты по всем перечисленным параметрам. Metabolism and its features determine the state of health of pigs, resistance of the organism to unfavourable environmental factors. Young stock of post-weaning age is especially susceptible to diseases of the gastrointestinal tract, pathogenic bacteria being their cause. Up to 100% of piglets suffer from these diseases. The factor on which the development of pathogenic microflora depends is the pH of the food digested in the stomach. The effect of the feed supplement BioAcidUltra developed to reduce the level of pathogenic microflora in feed and increase pig productivity was studied. Active ingredients of BioAcidUltra are formic acid – 14.45–19.55%; ammonium formate – 8.5–11.5%; propionic acid – 11.9–16.1%; ammonium propionate – 5.95–8.05%; lactic acid – 1.7–2.3%; silicic acid – 17–23%; vermiculite – 12.83–17.37%; diatomite – 8.84–11.96%; distilled water – up to 100%. The experiment was carried out in the conditions of a stud farm in the Tambov region on four groups of piglets for raising selected according to the principle of analogues (breed, age 21 days, live weight) placed in houses with the same management conditions. It has been established that the feed supplement BioAcidUltra added to the feed of piglets allows effective control of diarrhea when weaning them from sows and further rearing as well as has a positive effect on daily live weight gain. Researches have shown that anaerobic bacteria, representatives of normal microflora, occupy a dominant position in the intestines of animals of experimental groups. A biochemical blood test showed that in animals of experimental groups there was an increase in total protein, hemoglobin, calcium and phosphorus content and a decrease in urea content. The most effective dose of the BioAcidUltra feed acidulent was established in the diets of young animals during raising: a group of piglets fed a supplement in a dose of 3 kg / t of mixed feed showed the best results in all of the listed parameters.

Over Time

Development of calves depends on prenatal and postnatal conditions. Primiparous cows were still maturing during pregnancy, which can lead to negative intrauterine conditions and affect the calf’s metabolism. It is hypothesized that weaning calves at higher maturity has positive effects due to reduced metabolic stress. We aimed to evaluate effects of mothers’ parity and calves’ weaning age on growth performance and blood metabolites. Fifty-nine female Holstein calves (38.8 ± 5.3 kg birth weight, about 8 days old) were used in a 2 × 2 factorial experiment with factors weaning age (7 vs. 17 weeks) and parity of mother (primiparous vs. multiparous cows). Calves were randomly assigned one of these four groups. Live weight, live weight gain and morphometry increased over time and were greater in calves weaned later. Metabolic indicators except total protein were interactively affected by time and weaning age. Leptin remained low in early-weaned calves born to primiparous cows, while it increased in the other groups. The results suggest that weaning more mature calves has a positive effect on body growth, and calves born to primiparous cows particularly benefit from this weaning regimen. It also enables a smooth transition from liquid to solid feed, which might reduce the associated stress of weaning.

The purpose of research is increase the efficiency of the use of nutrients for rations by Simmental breed bulls with various doses of Vetosporin Suspension. Bulls were fed by probiotic in the amount of 0.1; 1 and 2 ml per 10 kg of live weight. It has been established that the use of rations including the feed supplement studied, in the feeding of experimental groups, promoted an increase in feed intake. Thus, the young growth of the three experimental groups exceeded the analogues of the control group for the consumption of hay grass by 37-118 kg (1.47-4.68%), green weight – by 31-71 kg (1.74-3.98%). Concentrates, molas-ses, fodder, and salt were given to the animals in the same amount. It can be stated that feeding to the Simmental bulls of different doses of the Vetosporin drug suspension had a positive effect on the digestibil-ity of the nutrients of the diet and their assimilation by the body. It is evident that in animals of experimental groups there is a certain superiority in certain indices over analogues of the control group. In this case, the animals of group I were inferior to the experimental groups by a digestibility factor of 1.03-2.24%, raw fat by 0.43-0.77%. For the rest of the indicators, there was a similar trend. When fattening Simmental bull calves, full-fledged and, importantly, balanced feeding was organized. Taking this into account, the use of probiotic fodder supplement, Vetosporin Suspension, contributed to greater consumption of all types of feed, nutrients and energy by animal test groups. In this case, the greatest effect was observed with the use of an approved additive in a dose of 1.0 ml per 10 kg of alive weight.

The main objective of this research was to verify the effect of feed mixtures supplemented with clinoptilolite-containing ZeoFeed (at a level of 1% and 2%) on the performance traits of broiler chickens in the period of their growth. Experimental results confirmed a positive effect of clinoptilolite on the performance of chickens which was demonstrated by a highly significant increase in the average live weight (P ≤ 0.01) of broiler chickens at 40 days of age. The average live weight of broiler chickens was 2.24 kg (at a dose of 1%) and 2.28 kg (at a dose of 2%) with feed conversion of 1.84 kg (at a dose of 1%) and 1.95 kg (at a dose of 2%) while the average live weight of control broiler chickens was 2.12 kg with feed conversion of 1.83 kg. No differences between both groups were found in water consumption. Chickens in all monitored groups showed very good health and a very low rate of mortality (3.75% in control group, 1.25% at a dose of 1% and 3.75% at a dose of 2%). It follows from the experiments that the clinoptilolite-containing product may serve as a suitable feed supplement to feed mixtures for broiler chickens.

To determine whether long-term sewage treatment can take place without a pollution risk for soil and groundwater, samples from sewage irrigation fields in West Berlin which have been in use since about 1890 were analyzed for enteric viruses and microorganisms. Enteric viruses were detected in only seven samples from a total number of eighty seven taken from different soil depths. With only one exception, no viruses were found below 60 cm. No viruses were detected in groundwater samples. Long-term sewage irrigation did not result in significant changes in the colony courts of aerobic soil bacteria, but the counts of anaerobic bacteria and actinomycetes were slightly elevated and those of microscopic fungi slightly decreased. Potentially pathogenic bacteria were not detected in soil below 90 cm.

Isolation And Characterization

ABSTRACT Fire blight, caused by plant pathogenic bacterium Erwinia amylovora, is one of the most important diseases of Rosaceae plants. Due to the lack of effective control measures, fire blight infections pose a recurrent threat on agricultural production worldwide. Recently, bacterial viruses, or bacteriophages, have been proposed as environmentally friendly natural antimicrobial agents for fire blight control. Here, we isolated a novel bacteriophage Hena1 with activity against E. amylovora. Further analysis revealed that Hena1 is a narrow-host-range lytic phage belonging to Myoviridae family. Its genome consists of a linear 148,842 bp dsDNA (48.42% GC content) encoding 240 ORFs and 23 tRNA genes. Based on virion structure and genomic composition, Hena1 was classified as a new species of bacteriophage subfamily Vequintavirinae. The comprehensive analysis of Hena1 genome may provide further insights into evolution of bacteriophages infecting plant pathogenic bacteria.

SummaryCross-breeding with European beef breeds has become a standard approach for the intensification of smallholder cattle production in Indonesia. This study assessed the environmental impact of cross-breeding, in terms of Global Warming Potential (GWP) and land use. We sampled 90 local Ongole and 162 cross-bred (Simmental × Ongole) cattle farms in four study areas. Expressed per kilogram of live weight of young stock produced, GWP (26.9 kg CO2–equivalents) and land use (34.2 m2) of farms with Ongole breeding stock were not significantly different from the GWP (28.9 kg CO2–equivalents) and land use (37.4 m2) of cross-bred farms. Cross-bred young stock grew faster, but in general cross-bred cattle required more feed. In the current smallholder production system, the dominant cross-breeding practice of using Simmental semen on Ongole andF1cross-bred cows does not result in lower greenhouse gas emissions or land use per kilogram of live weight produced compared with farms with Ongole cows. The advantage from the faster growth of cross-breds is counteracted by the higher emissions from feed production for cross-breds.

Taylorella Equigenitalis

In six healthy mares and 24 mares showing reproductive disorders swab samples were taken from the fossa clitoridis to isolate Taylorella equigenitalis, and from the uterus to isolate mycoplasmas, ureaplasmas and other aerobic bacteria. Swab samples were also taken from the uterus for Chlamydiaantigen ELISA and ChlamydiaPCR studies. The uterus of 27 mares was examined cytologically, and biopsy samples were taken from the endometrium for histological examinations and for immunohistochemical examinations aimed at the detection of chlamydiae. T. equigenitalis, mycoplasmas, ureaplasmas and chlamydiae could not be detected from any of the mares examined. Aerobic facultative pathogenic bacteria were isolated from mares with endometritis in four cases. In 18 out of 22 mares with endometritis (82%) no infective agents could be demonstrated. Further studies are needed to elucidate the relative importance of non-infectious causes of endometritis and of anaerobic bacteria often detectable in the uterus in the aetiology of the reproductive disorders observed.

Abstract The aim of this study was to develop a new strategy for processing of functional cooked sausages with reduced nitrites addition manufactured using pork obtained from pigs fed with a supplement of 3.5 and 7.5 mg dihydroquercetin (DHQ) (samples D1 and D2, respectively) or 0.255 and 0.545 g dry distilled rose petals (Rosa damascene) (DDRP) (samples R1 and R2, respectively)/kg live weight/d. The sensory properties, colour characteristics (L*, a*, b*), TBARS and shelf life of the sausages were studied. Lower concentration of used phytonutrients approve sensory acceptance of sausages with half added nitrites. Higher doses of DHQ and DDRP supplements increased the sausage pH by 3% (p < 0.05). The use of 0.545 g DDRP/kg live weight/d as a feed supplement with subsequent sausage production decreased the L* value and increased the redness (a*) in sausages while the higher doses of DHQ show an opposite effect. Feed enrichment with DHQ or DDRP is appropriate for manufacturing functional sausages with half added nitrites due to the stabilizing effect on colour (L*, a*, b*) characteristics in dynamics, the decreasing of TBARS and the increasing of the sausages shelf life.

В условиях научно-производственного опыта исследована эффективность введения кормовой добавки «Абиотоник» в рацион высокопродуктивных голштинизированных симментальских коров (в транзитный период и на раздое). «Абиотоник» представляет собой усовершенствованный аналог известного импортного препарата «Чиктоник», отличаясь от иностранного аналога многократно увеличенной концентрацией пептона и наличием высокодефицитных микроэлементов (селена и элементоорганического соединения йода). Наши исследования показали, что скармливание препарата «Абиотоник» в дозе 150 мл/гол. способствовало росту продуктивности коров на 5,84%, улучшило физико-химические свойства молока и повысило его пищевую ценность. Применение кормовой добавки способствовало также профилактике желудочно-кишечных заболеваний у коров, повышению их резистентности, о чём свидетельствовали показатели крови и бактериологического исследования кала. Заболеваемость коров в опытной группе не наблюдалась. Использование препарата «Абиотоник» коровам в заключительной стадии сухостойного периода и в начале лактации привело к сокращению времени отделения плаценты у коров после отёла на 6,54%, или на 0,4 часа, повышению живой массы новорождённого молодняка на 1,6% и сокращению сервис-периода у опытных коров на 8 дней по сравнению с контрольными. Использование кормовой добавки «Абиотоник» способствовало получению дополнительного дохода от реализации молока в размере 1152 руб./гол. Полученные экспериментальные данные позволяют рекомендовать использование отечественной импортозамещающей кормовой добавки «Абиотоник» в рационах коров транзитного периода и на раздое в дозе 150 мл/гол. ежедневно в последней фазе сухостоя и через день в течение 40 суток после отёла. Under the conditions of scientific and farm scale trial the efficiency of introduction of the feed additive "Abiotonic" into the diet of highly productive Holsteinized Simmental cows (during the transition period and for days in milk) was studied. "Abiotonic" is an improved analogue of the known imported preparation "Chiktonik" differing from the foreign analogue by its manifoldly increased peptone concentration and the presence of highly deficient microelements (selenium and organo-element compounds of iodine). Our researches have shown that feeding the preparation "Abiotonic" at a dose of 150 ml / head contributed to an increase in cow productivity by 5.84%, improved the physicochemical properties of milk and increased its nutritional value. The use of a feed additive also contributed to the prevention of gastrointestinal diseases in cows, an increase in their resistance as evidenced by haematological parameters and bacteriological feces analysis. The incidence of cows in the experimental group was not observed. The use of the preparation "Abiotonic" for cows in the final stage of the dry period and at the beginning of lactation reduced the time for separation of the placenta in cows after calving by 6.54% or 0.4 hours, increased the live weight of newborn young stock by 1.6% and reduced the service period of experienced cows by 8 days compared with the control ones. The use of the "Abiotonic" feed additive contributed to the receipt of additional income from the sale of milk in the amount of 1152 rubles / head. The obtained experimental data allow us to recommend the use of domestic import-substituting feed additive "Abiotonic" in the diets of cows in the transition period and for days in milk at a dose of 150 ml / head daily in the last phase of dry period and every other day for 40 days after calving.
