THE INDICES OF REPRODUCTION IN THE HERD OF MILK CATTLE IN “KUBAN” AGRICULTURAL HOLDING

abstract 1221608078 issue 122 pp. 1125 – 1162 31.10.2016 ru 452
The article contains complex research results dedicated of reproduction the cattle of the animal breeding industry in the agricultural holding called “Kuban”. Key indicators characterizing reproductive function at cows were set; they were estimated in terms of the plans of the economy in the milk cattle breeding industry. The reduced values of the birth-rate of calves were revealed on 100 cows and in the term of the production use of cows, their main reasons were set. The performed calculations prove the possibility of increasing the profitability of milk production

abstract 1041410108 issue 104 pp. 1542 – 1566 30.12.2014 ru 1475
The work on the development of technology for production of feed additives from soybean seeds and fruits of pumpkin has shown that the use of sodium bisulfate and lactic acid bacteria provide a high content of carotene in pumpkin paste (948 mg / kg and 819 mg / kg, respectively), and grinding soy before drying protein and vitamin supplements raises safety of carotene without destroying the urease

SUBSTANTIATION OF THE SIZE OF A COMBINED DEVICE FOR TILLAGE AND SOWING

abstract 1592005008 issue 159 pp. 122 – 132 29.05.2020 ru 162
The article presents a methodological approach to the rational selection of the optimal working width by the example of a combined tillage unit using original software. To select the optimal working width of a combined soil cultivating unit, the initial data are: make (type) of the tractor (power tool), unit cost of the machine and tractor unit in comparable prices, production time of the machine and tractor unit to perform the technological operation at a given operating speed with a clear compliance with agrotechnical requirements, both to the technological operation itself, and, directly, to the agricultural machine. As an example, we consider a combined semi-mounted modular tillage and sowing unit for grain crops and the MTZ-82.1 tractor. In this unit, the main working bodies are S-shaped spring teeth and rollers. Based on the performed analytical studies of the pre-sowing (surface) tillage process and the application of theoretical modeling methods, mathematical dependencies have been developed to determine and further analyze the energy-technological parameters of combined tillage units with dynamic working bodies. The performed calculations according to the developed method allow us to choose the optimal working width of the combined soil cultivating unit

RESULTS OF CALVING AND THE COMPOSITION OF THE BLOOD OF HEIFERS OF SIMMENTAL BREED, MOVED TO THE TAMAN PENINSULA FROM THE ASTRAKHAN REGION

abstract 1341710107 issue 134 pp. 1350 – 1367 29.12.2017 ru 355
The article contains data on results of calving and blood tests of heifers moved from the Astrakhan region in the Temryuk district of the Krasnodar region in the condition of early pregnancy. According to the accompanying documents, cell blood count, hemoglobin and biochemical parameters were consistent with species and age normal. Calving took place without complications and did not require delivery; received 36 of 36 calves from cows. The quality of the calves found to be satisfactory. On the 45th day of service period, clinical signs of impaired health status were present in 2 animals, however biochemical markers of liver disease, inflammation, and anemia was identified in 7 heifers. In the context of work on creation of livestock combined milk and meat productivity of inseminated heifers and heifers of the Simmental breed the Simmental semen (25 cows) and Aberdeen Angus (34 cows) breeds. Fruitfully inseminated 55 out of 60 animals; indicator of severity of calving was 8 % for Simmental cows. Calves of Simmental breed and Simmental-Aberdeen Angus cross-breeds meet the requirements for live weight at birth and the exterior. Farming on the formation of herds of milk and meat direction of productivity are found to be effective

PRODUCTION TECHNOLOGY PECULIARITIES OF LUCERNE JUICE COAGULATES

abstract 0951401005 issue 95 pp. 82 – 102 30.01.2014 ru 1096
During the study of different methods of fractiona-tion of alfalfa juice it was established that the most effective preservative of Lucerne juice is a composi-tion containing 2% of stock culture of lactic acid bacteria, 2% of molasses and 0.3% of benzoic acid, which preserves the functional properties of protein-vitamin feed additive

PROBIOTIC TRILAKTOBAKT IN FEEDING OF QUAIL

abstract 0951401004 issue 95 pp. 58 – 81 30.01.2014 ru 1947
During experiments on quail it was found that use of Trilaktobaktis probiotic is characterized with the activation of major types of metabolism, including protein –by increase the total protein content (5.17%) and mineral – by increase serum calcium and phosphorus (2.71 and 19.5%, respectively); by decrease of cholesterol content (10.6%). Probiotic stimulates erythro and hematopoiesis in quail: increase of the number of erythrocytes by 2.93% and hemoglobin by 2.57% was marked. Preparation enhances nonspecific resistance by increasing lysozyme and serum bactericidal activity by 47.4% and 149.6%.Besides, use of Trilaktobaktin diets increases digestibility of organic substance (5.74%), raw protein (3.95%) and raw fiber (4.83%). Probiotics use in the diet of quail improves nitrogen digestion by 5.3%, calcium and phosphorus – by 1.4%. Under the influence of probiotics content of lactic acid bacteria and bifidobacteriain chyme of quail increases by 46.2%.Use of Trilaktobaktin quail breeding increases safety and live weight gain by 6.0% and 6.9%, reduces the cost of feeds to produce 1 kg of body weight by 7.4%, and carcass yield reaches 66.4%, providing 100% output of first category carcasses. Use of Trilaktobakt feed additive has a positive effect on the quality of meat products. Thus, carcass output was 57.1% and the amount of fat decreased by 14.4% (pectoral muscles) and 12.7% (leg muscles) relative to the control. At the same time protein content in the thoracic and leg muscles increased by 7.5% and 10.7%

PECULIARITIES OF NON-INFECTIONAL ARTHRITIS IN GROWING POULTRY IN AN INDUSTRIAL ENVIRONMENT

abstract 1051501065 issue 105 pp. 1075 – 1097 30.01.2015 ru 1199
The problem of industrial poultry farming is the emergence of a growing birds’ arthritis. Inflamed joints are usually seen in poultry and accompanied by the inability to take food and water. The most characteristic of this problem in broiler chickens, young chickens of egg cross, i.e. birds of a short period of use. This is the reason for their rejection of the herd. Culling chickens are 10%, which furthermore reduces the total amount of livestock and leads to a reduction in the cost-effectiveness of growing birds. The analysis of our data gives a reason to believe that the main reason for culling poultry is acute inflammation of the joints or arthri-tis. According to the authors to ensure optimal rearing program, which should include the prevention of premature retirement of birds not only due to infectious diseases, but also the prevention of metabolic disorders and the exclusion of factors that could cause disruption of immunological reactivity. Currently, this program needs to be improved, which is particularly important in relation to vaccine pre-vention

MODELING REGIONAL SYSTEMS OF BREEDING PIGS

abstract 1141510076 issue 114 pp. 1004 – 1020 30.12.2015 ru 1141
The article contains the experience of the development of the methodology and the computer program for calculation of regional and local systems of pigs hybridization at the example of the Rostov region (Russia). Crossing the GP lines for F1 should be organized in multiplier farm, which may be separate farms and to be part of large commercial farms. For the production of F1 in a multiplier farm, we must breed a purebred specialized paternal and a maternal line, selected on the effect of combining ability. For the successful functioning of the system of hybridization, it is necessary to build a genetic pyramid, including breeding and genetic centers (nucleus farm), multiplier farm, reproducing the baseline. The article gives a detailed calculation of sow population of levels of P, GP, GGP for maternal and paternal breeds of pigs. The program uses user-defined parameters of pigs productivity, of the simulated population, and the parameters characterizing the intensity of selection of young animals. To ensure annual production of 1,822 million pigs in the Rostov region it is necessary to provide the availability of brood stock in the amount of 89 thousand heads, 6 800 heads in the structure of grandparent flocks (GP), 730 heads in the structure of the Grand-Grand-parent stock (GGP), excluding sows second maternal and paternal breeds
