Many Russian and foreign researchers outline the ethnological effect of BLV (Bovine leukemia virus) in cattle leucosis. The article highlights the stages of diseases, possible periods of concrete stages and features of antibodies’ resistance to BLV. The researchers’ view of temporary structure of Infection BLV is general and contradictory. The author carried out long-term chronohematological research (3 years) and found out wave-like arrhythmic dynamics of hematological indicators of the animals which suffer from leucosis. Each cycle includes remission stage and exacerbation of different degree. When leucosis results in tumor stage, the dynamics of hematological indicators was more intensed and oscillatory amplitude was higher. Leucosis tumor progression was observed together with development of clinic indicators like lymphadenopathy, exophtalm and rapid losing weight. We define the features of clinical implications and impermanence of this condition as clinical ones. The paper finds out that duration of more often registered cycles was 3,9,12,15,21,27,42,69,81, 108 and 144 days. The cycles are characterized by flexible, deep and long remissions changed by critical periods.

The paper explores detoxicative ability of buds and birch leaves on the modeling solutions. The authors explore the impact caused by buds and birch leaves ethanolic extract on blood biochemical characteristics of laboratory animals. The article reveals that application of raw materials extracts as detoxicants is efficient for biochemical status of animals.

Heavy use of laying hens at the poultry farms affects poultry physiological body systems. Poultry genetics assume its intensive metabolism, but monitoring of laying hens’ physiological condition is important problem. The research explored chicken groups of 15 and showed intensive blood-forming with high number of erythrocytes, leucocytes and hemoglobuline on the 35th day. The authors observe leukocytopenia in the period of lower productivity due to lymphopoiesis depression and activation of micro and macrophagal links of immunity system. Low concentration of hemoglobuline is observed in the periods of intensive productive burden of poultry and shows poultry depletion of inner resources.

Viruses play important role in animal diseases. There are many antivirus drugs in human medicine, whereas veterinary medicine uses just some antivirus drugs that makes difficult disease treatment. Generally, this treatment implies prevention of complications, i.e. application of antimicrobial and bracing drugs. The paper is devoted to new antiviral drug Coergine. The article finds out its significant virucidal action against the viruses of different taxonomic groups (herpesvirus, pestivirus, paramyxovirus) in the cell culture.

The paper explores biological effect of selenium in meat, liver and egg of poultry. The research investigated meat and liver of broilers and eggs that are commercially produced. The authors applied spectrometric methods of analyzing organic substances on concentration of macro and microelements. The authors analyzed the samples of production on Se element. Following methodological quidelines (МG 2.3.1.1915-04), the researchers made comparative analysis of nutritional value according to the recommended daily rates of consumption. The research on concentration of Se in the production found out high concentration of Se in meat- 0,36 mkg/g, liver of broilers- 0,88 mkg/g and in eggs- 0,38 mkg/g. High concentration of Se was not the result of application feeding additives that contain Se. The scientists see general Se concentration in poultry meat as 0,2 mkg/g and in eggs - 0,1-0,25 mkg/. Poultry products (eggs, poultry meat and broilers’ liver) produced according to the technology of functional ecoproducts can be used as products that complement human body with losses of Se.

The paper shows the results on feeding sows with probiotic MCD. The authors found out that feeding in the end of the second stage of pregnancy and during lactation influenced positively sows’ metabolism and physiological condition of newly-born piglets.

The paper describes 4 stages of calves’ newbornness. The first stage implies physiological changes in their organism when they don’t have their own antibodies until feeding with colostral milk. The 2nd stage lasts from 24 to 36 hr when calves start making high number of antibodies in case of efficient colostral milk feeding. The 3d stage finishes colostral milk feeding; the 4th stage assumes the end of colostral milk producing when milk is produced and own immune system of the calves.

The article explores the results of cross-breeding of fine-wooled hair sheep with Siberian sheep of Soviet meat and hair breed. Their use is efficient for cross-breeding of sheep in the forest steppe of Novosibirsk region.

The paper shows research results on ethological features of young cattle and Aberdeen Angus cows and Hereford cows. The experiment was carried out at Zaprudinskoe farm (Krasnozerskiy district of Novosibirsk region) in 2015-2016. The authors kept young cattle together with cows in the same conditions; the animals were fed and kept according to the system endorsed in meat cattle breeding. The research arranged meat calves in groups of 50. The researchers didn’t observe certain characteristics on investigated parameters (ethological and biological) either in the young cattle and in the meat cows. The authors make conclusion that both these breed can adjust to the conditions of western Siberia and can be used for herd expansion and beef production.

The paper studies publishing activity in the area of agriculture in western Siberia in the beginning of XX century. The author shows typology and topics of publications. The material demonstrates the research data in statistic figures and tables.
