BIOLOGICAL FUNCTIONS OF CAROTENOIDS AT CATTLE REPRODUCTION

abstract 1291705080 issue 129 pp. 1113 – 1125 31.05.2017 ru 138
Carotenoid preparations are quite widely used in a health care, but in the veterinary and animal husbandry, their use is limited. In terms of livestock farms of the Krasnodar region and the Rostov region at the biochemical monitoring studies of the cattle blood the lack of carotene in the serum is revealed from 45 to 100 % of the samples. To study the biological function of carotenoid we used preparations, which are the oily solutions for injections: β-carotene (manufactured by FS 42-3867, which is produced from the biomass culture of the fungus Blakeslea trispora) and lycopene, emitted from plants. The cows in the test groups during the dry period and within two weeks after birth got carotenoid preparation subcutaneously at a dose of 10 ml per animal with an interval of 7 days. As a result, it was found out that the application of carotenoids has the most favorable conditions for the flow of labor and the postnatal period, which are manifested in the decrease in obstetric and gynecological diseases in cows and reduce the period of infertility. In the experimental groups the levels of vitamin A and carotene1,3 times higher (1,26 ± 0,14 μmol/L vs. 0,97 ± 0,09 μmol/L ) 1,8 times (0,34 ± 0 03 mg /% vs. 0.61 ± 0.11 mg /%) respectively in comparison with the parameters of the intact animals at a high level of confidence (P < 0,05). Phagocytic number and percentage of digestion of neutrophils increased by 8,5 %, the difference in the number of B-cells reached 9,1%, T-cells – 6,7%. In a humoral immunity found a significant increase in Ig A. After comparison of the level of lysozyme activity of blood serum was observed its reduction in all animals immediately after birth, but in the experimental groups this process was less pronounced. The use of carotene preparations helps to reduce the concentration of lipid peroxidation products in the body of cows (diene conjugates - by 16,6 %, ketodienes - by 35,7 %, malondialdehyde – by 11,3 %), which creates favorable conditions for the flow of the metabolic processes associated with ensuring the normal childbirth and post-partum involution of the genitals. In the group of cows, receiving the carotenoid lycopene, the dyspepsia morbidity of the newborn calves compared to a control decreased by 26,7 %, bronchopneumonia - by 13,3 %

abstract 0931309078 issue 93 pp. 1146 – 1164 30.11.2013 ru 570
In the work, we have presented the information of elaboration of a manufacturing process of Mycocel feed additive with the cellulolytic activity for poul-try industry. Manufacturing process includes follow-ing steps: stock culture maintenance and storage of Trichoderma lignorum 81-17, growing fluid culture of microscopic fungus in sucrose yeast extract me-dium, feed additive with cellulolytic properties out-put and quality control, packaging, storage and disposal of waste. We have shown that the Mycocel is non-toxic feed additive for protozoa and warm-blooded animals (laboratory mice and quails). This study demonstrated total population livability in the experimental group with feed additive. Quail body-weight of experimental group was higher by 6% as compared to the control and feed consumption per 1 kg of live weight of bird was 3,58 kg, 7,5% lower than the control

DEVELOPING LOW TEMPERATURE SOURCE LOCAL HEATING FOR PIGLETS

abstract 1081504056 issue 108 pp. 761 – 778 30.04.2015 ru 416
During the research, we have developed a low-temperature zonal heating panels with an infrared emitter to create a local microclimate for piglets in the suckling period. This heater is lightweight and durable frame in the form of an inverted box size 400 mm x 1800 mm, attached to the wall of the building swivel. Top frame mounted thermostat is connected to a temperature sensor mounted directly on a metal plate with a thickness of 1 mm, painted in black color. In the upper part of the inner carcass layer is a light insulating material, which is located directly under the low-temperature heat source is electric. Study of the optimal size of the heating panel revealed that in view of the limitations associated with the area of the machine and biological characteristics of the optimum size of the sow for 11 piglets are: width – 400 mm; length – 1500 mm (at ventral position) and 1800 mm (lateral position). Comparison of different heating sources for piglets revealed that the use of infrared lamps enables newborn piglets seating area by 55.6%, while in 28 days – by 88.9%. Infrared lamps can not completely meet the recommended specifications as to ensure a more intense heat lamp to be lowered towards the floor surface, which leads to a reduction in the useful area heated. Using as a source of local heating mats and low-temperature panels satisfies pigs in the area of the den in the early suckling period at 138.9 and 200.0%, to weaning, respectively – by 48.5 and 65.5%. Thus, we have developed a low-temperature heating panels contributed to a more uniform distribution of heat in a recreation area of suckling piglets and to provide a comfortable environment at temperatures of 2-3 C lower in comparison with other methods of heating

ECONOMIC-BIOLOGICAL FEATURES AND EXTERIOR MAINTENANCE OF YOUNG CATTLE IN THE KRASNODAR REGION

abstract 1051501064 issue 105 pp. 1046 – 1074 30.01.2015 ru 316
In the Krasnodar region there is a unique gene pool of animals both for dairy and meat. To assess the heifers the authors formed five experimental groups of animals, the most common species in the region. The authors studied the main economic, biological and exterior features: live weight, measurements, assessment of the exterior. The studies found that among intensive species with the largest body weight throughout the growing period, in 8-month old Charolais heifers superior Simmental ones at 17.4 kg. In one year old Simmental heifers were 9.2 kg (R˂0,05) ahead of Charolais and in 15 months – 10 kg (R˂0,05). Over the entire period of growth the highest rates of relative growth rates of heifers were obtained by red steppe breed type named Kuban, which had an advantage over the Aberdeen-Angus – 19.1%, Charolais – 5.6%, Hereford – 6.2%, and the difference between them and Simmental weren’t fixed. When growing, the animals become less tall, more stretched, wide and massive. We have noted that during the period of cultivation we had increased indices: stretch (9% – Red Steppe, 13.8% – Charolais, 16.1% – Hereford); chest (5.4% Aberdeen Angus). This reduces the index of long legs of red steppe – 5.6%, 10.9% for Charolais. The study of linear growth of animals confirms that the animal meat breeds of live weight increase was due to the extension of the body and increase the width of the pelvis and chest. Some different facts were observed in heifers of Red Steppe breed. For them, the most characteristic increase in the width of the chest was 1.44 times, as well as increasing the depth of the chest and chest girth behind the shoulders

abstract 1241610069 issue 124 pp. 1065 – 1084 30.12.2016 ru 164
In this study we show the results of the use of natural mineral compounds in metabolic disorders in cattle-breeding complexes of industrial type. According to official data for 2013-2015, based on the biochemical analysis of blood of cattle, that was held in some farms of Samara region, significant metabolic disorders were determined due to decrease in total protein level on 31,5% in average, decrease in alkali reserve – on 26,9% of samples, decrease in calcium concentration – on 40,7%, decrease of the phosphorus – on 8,1%, decrease in carotene – on 81,7% and glucose – on 84,3% of studies. Clinical examination of herd revealed a high level of animals with obvious signs of mineral metabolism disorders (osteodystrophy and rickets of alimentary origin) and comorbidity (nutritional anemia, gastroenteritis, pneumonia, disturbance of protein, carbohydrate and vitamin metabolism, and others). The use of complex natural compounds improves the efficiency of the traditional complex of treatment and prophylaxis, causing an increase in the total concentration of calcium in the blood serum on 10-55%, increase in calcium-phosphorus ratio till 1,27-2,3, increase in annual growth rate of young animals’ body weight on 8,2-44,8%, increase in milk production on 5,9-16,3%. Preparations have an antianemic action, normalize indicators of micronutrient metabolism of proteins and carbohydrates, enhance non-specific resistance factors and prevent the development of non-contagious internal pathology

FUNCTION FEED ADDITIVE OF CAROTE-NOID VEGETABLE RAW MATERIALS FOR POULTRY

abstract 0931309079 issue 93 pp. 1165 – 1184 30.11.2013 ru 556
The article is concerned with the use of functional feed additives from pumpkin fruits and alfalfa juice for the poultry industry. In the study of laying hen it has been found that the use of a feed additive in-creased pumpkin paste content in serum and egg yolk carotenoids is more than two times, and the concentration of vitamin A in these tissues increased slightly, not exceeding 20%. Livability and productivity of poultry increased and average expendable fodder per head per day decreased. Economic calculation showed that the use of pumpkin paste reduces the cost of production of eggs. The use of alfalfa juice coagulates in diets for broiler chickens resulted in an increase in the concentration of carotene in the liver by 22,7-46,8% relative to control. The juice addition also increased the content of vitamin A in the liver by 27.9%, increase the safety and efficiency of the bird. The authors draw certain conclusions from experiment results that the use of functional additives in poultry from the fruit of pumpkin and alfalfa juice is an alternative to synthetic vitamin preparations and produce a more environmentally friendly products
