The task is to set the functional dependence between the prepared mixtures quality and the empirical ratio of the intensity of mixing, taking into account the blades length in regard to values of the rotation frequency and the length of the blade of the batch-operated mixer, as well as the definition of rational length of the mixer blades. Improving the quality of mixture requires both the adding of all nec-essary nutrients and feed components into the volume of prepared portion of the mixture as stipulated by the recipe for mixture, and smooth distribution of components throughout the volume of ready feed. Smooth distribution of the mixture components is related to the design and operation of the mixer. Blade mixer batch- operated is one of the effective types of existing mixers, mixing the ingredients of feed with good quality. The article presents the result oriented design scheme of the blade mixer. Positive functions of the mixture quality and the empirical coefficient of mixing intensity included in their composition are assessed taking into account the length of the blades, depending on the rotation speed and frequency of the mixer. The graphic results of experimental studies taking into account the influence of the blade length and the speed of the mixer on the quality of the prepared mixture are given. The increase of blade length and rotation speed improves the quality of the mixture. Recommended blade length is 75...80 mm. With frequency of rotation increase and the length of the blades the total value of the empirical coeffi-cient of the intensity of mixing, depending on the effect of the length of the blades decreases at a slower pace. This is typical of the obtained hyperbolic dependence.","PeriodicalId":393002,"journal":{"name":"Bulletin Samara State Agricultural Academy","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126541154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various synthetic films are used to provide soft covering. Long materials are wound into a roll for convenience of transportation and storage. Appropriate equipment is needed for the operation to be performed. Main problems arising during material winding into a roll have been considered. The first problem is related to the weight increase of the roll due to its diameter change during the winding process. This augments the load on the horizontal rollers and their supports. The second challenge follows the first one: roll parameters change leads to a change of friction forces between the material wound and rollers, which in turn reduces the quality of the roll winding and affects its geometry and density. The presence of skew material during the roll winding leading to an increase in the length of the roll and its looseness is one of mentioned above disadvantage. This significantly complicates both the winding of the material into the roll, its transportation and film unwinding. The equipment for the winding of the film (material) offered is to be provided with automatic devices to compensate the roll weight able to eliminate this disadvantage. The design description for winding roll equipment is supplied. The original designs for equipment with automatically operated drives have been developed to improve the quality of winding. The roll-ers rotation speed was estimated according to the film thickness on the basis of the power analysis performed. The results of studies allow establishing the critical parameters of the hydraulic system for proving control over the work-ing process.","PeriodicalId":393002,"journal":{"name":"Bulletin Samara State Agricultural Academy","volume":"905 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123267847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The morphological composition of blood is one of the main informative systems and has long attracted the attention of researchers. Blood, as a co-single tissue, has been studied well enough. Its indicators are the main fac-tors in determining the state of an animal health, as well as pointing out the presence of pathological processes in inside the organism. To determine the effect of complex use of STEMB (embryonic stimulator) and Uteromastin on the blood parameters of cows in comparison with individual administration three groups of pregnant cows \u0000(7.0-8.0 months) were formed separately, each with 20 heads in compliance with the method of groups-analogues (experimental-1, experimental-2, experimental-3). Animals in groups to be examined were provided the same con-ditions both in feeding and keeping. Animals of the first experimental group 25-30 days before calving were admin-istered STEMB drug hypodermic in the neck at a dose of 0.075 ml per 1 kg of live weight with an interval of 7 days three times, animals of the second experimental group were administered the drug Uteromastin 8-10 hours after calving intrauterine at a dose of 150 ml once. Cows of the third experimental group were administered drugs STEMB and Uteromastin in these doses (mixed). The influence of the complex use of drugs STEMB and Utero-mastin on morphological, biochemical and immunobiological parameters of blood of cows were studied on the 15th day after calving. The use of the drugs STEMB and Pteromalid complex improves cellular composition of the blood and indices of the blood serum, which enhances immunotoxicol system of organism of cows.","PeriodicalId":393002,"journal":{"name":"Bulletin Samara State Agricultural Academy","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132623509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The studies were conducted by the fodder crop rotation laboratory staff of The Department of plant growing and agriculture of the Samara State Agricultural Academy on the base of field experience, taking into account the technical tips for field experiments with fodder crops. The article stipulates the results of studies taking into account the period between 2015-2018, with the assessment of seed quality, seed-ling emergence, plant height and overhead weight gain. The study of the herbage on the basis of the Awnless brome showed that good indicators of herbage formation parameters are achieved with bean components use. The best option Awnless brome + Smooth brome + Hungarian sainfoin, but mixture Awnless brome + Smooth brome + Alfalfa Sinegibridnaya provides herbage quality as well. Observations showed that the growth of culm in height occurs gradually from the beginning of vegetation (the grass tillering phase and branching in legumes) to the phase of fruit formation; the more components in the grass mixture, the higher its productivity. The use of rosta stim-ulants (Gumi 20M and Growth Matrix) leads to change in the parameters of herbage and the accumulation of over-head mass.

The \u0000natural and climatic conditions of the southern part of the Ryazan region are favorable for the cultivation of oilseeds and are characterized by the following indicators: the sum of the active air temperatures is 2200-2350°C, the rain-fall during the growing period is 510-560 mm. As a result of the measurements of the main morphometric parame-ters, Larissa and Samanta, were identified as the tallest hybrids. The average height of plants produced by these hybrids reached 219 and 205 cm, respectively. The BA-306 hybrid (176 cm) had the smallest parameters. Walcer hybrid plants formed the largest area of the assimilation surface and amounted to 31.6 thousand m2/ha. The area of the leaves of other Hungarian sunflower hybrids was less by 11.0-19.9%. The lowest values of this indicator were observed in the hybrid Nova. In Samanta, Walcer and Larissa hybrids, the diameter of the anthodium exceed-ed 21 cm. However, the Samanta hybrid anthodium resulted in the smallest productive area – 73.5%. The largest mass of \u00001000 seeds was obtained from hybrids BA-306 and Nova and amounted to 61.4 and 62.2 g respectively. Due to the yield, the Hungarian hybrids were arranged in the following order: Nova, Samanta, Larissa, BA-306, Walcer. This pattern was observed both taken from average values over the years of research, during each year separately. The oil content of all studied sunflower hybrids was high and amounted to 48.4-51.2%.
