Fungi of the genus Aspergillus as a factor in the occurrence of lung diseases of young cattle in the Republic of Mari El

At the present stage of economic development of the Republic of Kazakhstan dairy cattle breeding should be competitive, highly productive and cost-effective, which contributes to ensuring the country’s independence from imports of dairy products. The formation of milk productivity of future cows begins with the preparation of cows for calving and the purposeful rearing of replacement young cattle, based on the achievements of scientific and technical progress, a systematic approach to the production of high-quality products. The researches have been carried out in the farm “Tauelsizdik” in the Eskeldinsky district in the Almaty region in the Republic of Kazakhstan. According to the results of the research, the average daily gain of live weight in 3 months of the post-embryonic period was 458,9±71,9 g in heifers have reared in narrow-sized pens, and 682,2±44,6 g in heifers have reared in group pens. At 3 months of age the live weight of heifers at rearing in narrow-sized pens has reached 76,5±2,5 kg in narrow-sized pens, and 98,3±1,7 kg in group pens (P < 0,001). The data of the experiment have convincingly shown the effectiveness of rearing heifers in group pens. The live weight of heifers at birth was 36,4±1,1 kg, at one month of age – 54,2±1,6 kg, at 2 months of age the live weight increased to 70,2±2,1 kg, at 3 months of age to 87,4±3,3 kg, at 4 months of age to 116,8±3,5 kg, at 5 months of age to 132,7±4,2 kg and at 6 months of age to 157,4±4,6 kg. The indices of lengthiness, chest, hip-chest and blockiness increased up with age, while the indices of high-leg and overgrown decreased down. For example, the lengthiness index has increased with age from 90 to 97 %, the chest index from 62 to 70, and the high-leg index has decreased from 59 to 54, overgrowth from 109 to 108 %.

This paper presents the results of studying the conversion of feed into nutrients in the carcass of bulls during the fattening of young Kalmyk breed in the conditions of Yakutia. The studies were carried out on the basis of the Soloosun agricultural production complex, Megino-Kangalassky region. The experiment was organized on Kalmyk bull-calves fed from 15 to 18 months of age. There were formed 2 groups of 25 bulls analogs: the control and the experimental one. The animals of the control group were fed according to the ration adopted on the farm. The diet of the animals from the experimental group included 200 g of Hongurin zeolite and 45 g of Kempendyai salt per animal. The main ration of animals by structure consisted of meadow hay 46%, haylage – 22% and compound feed 32% or 12.57 EFU per day. At the beginning of the experiment, the live weight of the animals was almost identical. At the end of fattening, the bulls of the experimental group in live weight exceeded the animals of the control group by 10.9 kg. Consequently, the experienced bulls had higher bioconversion rates, which was reflected in an increase in the meat productivity of animals. The analysis showed that the control group of bulls was inferior to the experimental group in terms of pulp by 11 kg., In the deposition of food protein by 1.3 kg. The calculation of the data on the conversion of protein into food protein showed that in the control group this indicator is 5%, and in the experimental group it was 6.2%. The yield of dietary protein in the control group was 40.4 g, in the experimental group – 52.8 g. Thus, the calculation of bioconversion showed that the animals of the experimental groups, which additionally consumed Hongurin zeolite and Kempendyai salt, had a higher ability to transfer nutrients and feed energy into meat products. The indicators of economic efficiency per 100 heads of fattening bulls of the Kalmyk breed are: profitability – 122.53%, cost price 1132 thousand rubles, profit – 1,388 thousand rubles, profit – 1.23 rubles per 1 ruble costs. The efficiency of beef production at a specialized feedlot increases by 22.53%.

Introduction/Objective. Previous studies have confirmed the effect of different meteorological parameters on patients suffering from lung diseases. The objective of the study is to investigate the impact of meteorological phases on the death rate from chronic obstructive pulmonary disease (COPD). Methods. The data on the number of deaths caused by COPD and meteorological phases during a five-year period (2011?2015) in Sumadija District (Central Serbia) were obtained from the Republic Hydrometeorological Service and the Center for Biostatistics and Informatics of the Kragujevac Institute of Public Health. Results. A statistically significant correlation was determined between certain meteorological phases and COPD death rate. The highest death rate was determined during colder months, February and March. The lowest death rate was detected during the warm months (June?September). Although men died more often from COPD than women, the death rate of women showed a considerable increase during the five-year period. Conclusion. COPD death rate is highly dependent on the season of the year and might be associated with certain meteorological phases. There is a need for further research of the impact of meteorological phases on the morbidity and mortality from COPD.

This work is based on helminthological data of amphibians, collected since 2013 until 2020, in the Republic of Moldova. The investigations on anura amphibians were conducted in the laboratory of Parazitology and Helminthology of the Institute of Zoology. One of the most common parasitic diseases in ruminants is fasciolosis, caused by the trematode Fasciola hepatica species. The results of parasitological research showed that adult cattle were infected with fascioles in 66.4% of cases, and young cattle - in 46.1% of cases. This is largely due to the grazing of animals of different species and ages in limited areas.The presence of the trematode species Haplometra cylindracea was established in 78% of cases in the amphibians in the Ranidae and Bufonidae families (Rana ridibunda, Rana lessonae, Rana temporaria, Bufo viridis). The results of laboratory helminthological investigations have shown that the relationships between the Fasciola hepatica miracidium and the Haplometra cylindracea miracidium are antagonistic. Amphibians of the Ranidae and Bufonidae families (Rana ridibunda, Rana lessonae, Rana temporaria, Bufo viridis) infested with Haplometra cylindracea tremateda may play an important role in the prophylaxis of fasciolosis.

Daily Gain

Numerous studies have shown that animals with the same genetic potential can differ in productiveness. In this regard, specialists in this industry, when predicting the milk productivity of adult animals in the process of raising young cattle, divide rearing into separate periods. In order to study the conditions for growing dairy calves, a comparative analysis of the conditions for keeping and feeding calves in two farms of the Republic of Tyva was carried out. The conditions of growing calves in the dairy period in the conditions of different farms with the same breed composition of cattle were studied. A comparative analysis of the influence of the composition and level of the diet on the growth of young animals is given. Calves of both groups by birth weight at birth did not have significant differences: they were 0.05-0.07 kg. In dairy farms MUP “KaaKhemsky” and “OOO Turanskoye” young cattle from birth to 6 months are kept in separate rooms. There are no significant differences in the calf feeding schedule. In the Municipal Unitary Enterprise “Kaa-Khemsky” feeding with haylage of young animals is introduced from two months of age; at the farm of “OOO Turanskoye” silage has been given to calves from 4 months. However, from 4 months to six months of age, they showed a significant difference in the increase in live weight. At 4 months, the difference averaged 4.27 kg, at 5 and 6 months – 6.39 and 8.59 kg, respectively. As a result of the studies, it was concluded that a decrease in the drinking of whole milk and the introduction of a substitute at its early, three-month-old age, which are compensated by a large intake of hay, feed and silage, do not provide a high average daily gain in live weight of the growing organism of young cattle.

The paper explores parasitic diseases of calves and young cattle in the Republic of Belarus and finds out that they are mainly revealed as parasitocenosis with great diversity of followers. The agents of gastrointestinal parasitocenosis and the degree of infestation by them are closely related with the age of an animal. Associative parasitosis was observed in calves aged 2 months. The authors designed the composition of complex specimen Viracoccha, which includes modern anticoccidial, anthelmintic, organic acids and tocopherol acetate. This concentration allows to treat animals from parasitic protozoa and helminthes and protect their immune system. When exploring acute and chronic toxicity of new complex specimen Viracoccha, the authors highlight that it does not cause any deviations from the physiological norm in clinical condition in mice and according to GOST 12.1.007-76 Harmful substances belong to the 4th class of hazard (low hazard substances), it does not spoil the skin of laboratory animals and does not have sensitizing (allergenic) ability, it does not cause intoxication and any deviations from the physiological norm in rabbits which receive specimen as preventive specimen and 3 times exceeding dose. The effect of Viracoccha dosed 100 mg/kg of live weight in the associative infestation (Strongyloides+ Eimeria) of calves was 100%.

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.
