The study of the productive traits of chickens when fed sunflower polysaccharide extract (hereinafter referred to as SPE), which can activate protein and carbohydrate metabolism, stimulate the body's natural defense factors. Materials and Мethods. The studies were carried out in a certified laboratory using classical and modern zootechnical, biochemical and other methods. Laboratory hematological studies were carried out on automatic biochemical analyzers URIT-800Vet and URIT-3020 (China) in the complex analytical laboratory of VRIMMP (Volgograd, Russia). The obtained results were processed using the software, calculation of the mean (M), standard errors of the mean (±SEM) and determination of the Student-Fisher test for the significance of the difference. Results. In I-III experimental groups, an increase in the yield of hatching eggs was recorded, respectively, by 88, 239 and 149 pcs. relative to the control, the intensity of egg production of hens – by 0.65; 1.35 and 0.77%, feed conversion per unit of egg mass – by 0.03; 0.07 and 0.05 kg. There has been a steady trend towards an increase in the mass of eggs in the experimental groups by 0.27 (0.43%); 0.81 (1.29%) and 0.63 g (1.01%), the acid number of the yolk decreased by 8.01 relative to the control; 9.42 (P≤0.05) and 10.29% (P≤0.05), which suggests the presence of antioxidant properties of PPE. The use of the studied additive had a positive effect on the morphological composition of the blood of laying hens of the experimental groups: the content of erythrocytes increased by 15.41 (P≤0.05), 17.47 (P≤0.05) and 17.81% (P≤0, 05), hematocrit – by 5.57 (P≤0.05); 10.22 (P≤0.01) and 11.15% (P≤0.01), hemoglobin – by 6.25 (P≤0.05), 8.67 (P≤0.05) and 9.19 % (P≤0.05) against the background of the control.

To study the methods of restoration (reclamation) of disturbed pasture lands based on the comparative aspect of the yield of perennial fodder grasses when creating pastures in the arid regions of the Lower Volga region. Materials and Methods. In the course of the experiment, a comparative study of the ecological and biological properties of perennial fodder grasses was carried out (Colognes rush, Desert wheatgrass, Sandy spare, Couch grass elongated. The experiment was carried out on a prepared field (plowing, harrowing), divided into experimental plots of 50 m2 in size. It was carried out at the end of autumn (November) to a depth of 20-30 mm with a row spacing of 0.45 m. The repetition of reseeding in the experiment was two times. Results. Variation in the yield of dry eaten mass between the control variant of natural pastures and the experimental plots of the tested grasses has been experimentally proven. Among the tested herbs, the highest yield was shown by sandy sirloin (III experimental plot), which amounted to 2.43 t/ha of dry mass eaten. The excess of this indicator relative to experimental plot II (desert wheatgrass) was 7.05%, experimental plot I (rush hair) – 18.54%, experimental plot IV (elongated wheatgrass) – 28.57%, and relative to the control plot (natural forms) the increase in yield was 3.4-4.3 times, depending on the type of herbs tested. Conclusion. Pasture grasses occupy a key place in the development of productive pastures in the arid zone of the Lower Volga region. They have high water and energy efficiency regardless of low humidity conditions, providing stable grass production to support livestock. The bearing capacity of rangelands can be improved with available technologies if they are applied and adapted on a long-term basis. Low-productive rangelands that lead to imbalances in forage production must be restored through low-cost methods such as reseeding to provide more and higher quality forage for livestock and soil protection. Reseeding can provide high plant density at low cost and is a cheap means of providing adequate feed for livestock and increasing income from grazing. An increase in yield by 3.4-4.3 times relative to the control plot (natural forms) is achieved by reseeding natural pastures with the appropriate types of grasses suitable for macroclimatic subregions.","PeriodicalId":7676,"journal":{"name":"Agrarian-And-Food Innovations","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139310207","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 study of the relationship between the age of the highest productivity for lactation and the further duration of the period of economic use of cows. Materials and Methods. The work was carried out in the conditions of the dairy complex of LLC Agricultural Enterprise \"Donskoye\" in the Volgograd region. The object of the study is cows of Danish selection, uniform in date of birth, time of insemination and calving, which were culled from the herd in the period from 2016 to 2020. Statistical analysis of zootechnical and breeding records data and productive indicators of the animals participating in the experiment was carried out using the information and analytical system “SELEX – Dairy Cattle” (RC PLINOR LLC, Russia) and the Dairy Plan computer program (Germany). Results. The conducted studies established that the early age of peak lactation did not have a positive effect on increasing the period of productive and economic use of Holstein cows of Danish selection. It was also noted that a decrease in milk yield during lactation prolongs the period of economic use of animals and, accordingly, longer operation increases the lifetime productivity of cows. The highest milk yield for lactation in the amount of 10633.3 kg and the average milk yield for all lactations at the level of 9742.1 kg make it possible to obtain a lifetime milk yield of 34088.3 kg with a productive duration of 3.5 lactations. The productive potential of these animals, revealed during the second lactation, is 11,000.8 kg. Conclusion. The extension of the period of productive use to 3.5 lactations, that is, four calvings, for highly productive cows of Danish selection is possible with an average milk yield per lactation of 9742.1 kg, while the lifetime milk yield per cow will be 34000.0 kg of milk.","PeriodicalId":7676,"journal":{"name":"Agrarian-And-Food Innovations","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139310705","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 study of the productive traits of chickens when fed with a prebiotic supplement that stimulates the antioxidant and immunological defenses of the body Materials and Methods. The studies were carried out in certified laboratories. The resulting digital material was processed using the statistical package Microsoft Excel, which provides verification of the reliability of the data using the Student's criterion. Results. It has been established that the introduction of the feed additive \"LactuSuper\" into the diet of laying hens of the Hisex Brown cross dramatically increases their productivity by 85 eggs in 10 weeks of the experiment, or by 1.2 eggs per positive laying hen, the egg-laying intensity – by 1.74%, feed savings – by 0.6 g per day per head, obtaining a hatching egg yield of 4% (97% compared to 93% of the control group). The balance of the feed additive \"LactuSuper\" with biologically active absorbed absorbable carotenoids in the yolk of the incubation eggs of the experimental group was 23.36% (P≤0.001), which was 16.9 µg/g in absolute values. Incubation of eggs showed a high hatch of chickens in both groups (82.44 and 85.27%), but in the experimental group, the excess in this indicator was 2.83%. High rates of production and quality of hatching eggs in the experimental group, apparently, are provided by the activation of metabolism in the body of chickens, as a result of feeding them the studied additive. Due to the antioxidant properties of the tested feed additive the activity of superoxide dismutase (SOD) increased by 11.22% (P≤0.01), glutathione peroxidase (GPO) – by 3.02% (P≤0.05), ceruloplasmin (CP) – by 16.58% (P≤0.01), total antioxidants (TOA) by 26.97% (P≤0.01), and malondialdehyde (MDA) activity decreased by 14.15% (P≤0,01). The level of T-lymphocytes responsible for cellular immunity increased by 12.61% (P≤0.01), and the content of B-lymphocytes characterizing humoral resistance increased by 6.83% (P≤0.05) relative to the control. An increase in the level of classical antibodies was recorded in the experimental group. Thus, the content of IgA and IgG increased by 17.26 (P≤0.01) and 7.62% (P≤0.05) compared with the control.

When performing the work, both conventional research methods and modern instrumental, zootechnical, biochemical, and chemical methods were used, which were carried out in certified laboratories. The resulting digital material was processed using the Microsoft Excel statistical package, the reliability of the data was checked using the Student's t-test. Results. Amaranth, as a valuable source of nutrients, has the potential to meet the nutritional requirements of poultry. According to the data obtained, feeding amaranth to laying hens, either alone or in combination with a multi-enzyme complex, can lead to the production of food eggs with a low cholesterol content without any negative impact on their quality. In parallel, the antioxidant status and the atherogenic index (LDL/HDL) of birds are improving. In addition, feeding amaranth with enzyme supplements led to an increase in the productivity of laying hens. Conclusion. In general, the results of our study show that feeding amaranth grain favorably affects the health parameters of laying hens by improving antioxidant status, as well as lowering cholesterol, LDL and triglycerides, while increasing blood HDL levels. It should be noted that the indicators of productivity and quality of eggs improve when a multi-enzyme complex is included in the diet containing amaranth grains at a dose of 250 g/t of feed. The high content of crude protein in amaranth grain and the presence in it of substances with antioxidant activity make it possible to use it as a feed agent in industrial poultry farming. It is known that egg yolk cholesterol determines the nutritional value of the product.

Scientific and practical substantiation of the positive impact of the developed new feed additives on the metabolism of farm animals and poultry. Materials and Methods. The studies were carried out using traditional scientific methods of collecting information, processing primary material, generalization, and systematization. The analysis of biochemical, zootechnical, morphological, histological, organoleptic, functional and technological indicators was carried out in accordance with the generally accepted normative and technical documentation. Discussion. It has been proven that the use of natural sorbents and minerals (bentonites, diatomites, limestones, various fractions of bischofite), secondary raw materials and food production wastes (cake, meal, pomace) in the composition of feed for cattle makes it possible to reduce the technogenic load on the animal body (in 3-6 times), increase the level of conversion of feed nutrients (16-40%), improve metabolic processes, increase productivity (10-16%) and the level of profitability of the industry (7-14%). At the same time, animals of different breeds and directions of productivity differ in their ability to accumulate ecotoxicants. Inclusion in the diet of a vitamin-mineral complex containing betacarotene, vitamins E, C and selenium in a bioavailable form makes it possible to eliminate the stress factor that occurs during the parenteral administration of a commercial two-component analogue and achieve a more significant physiological effect on the body of lactating cows. The developed protein-mineral preparations containing bioavailable forms of iodine and selenium, feed additives based on lactulose in combination with honey extracts of highly valuable plant materials, biologically active complexes of lactulose and regional natural resources stimulate immune mechanisms, contribute to the formation of the functional properties of livestock products, which is especially important in the prevention of alimentary-dependent conditions in the population. Laying hens that consumed enriched feed used the nutrients of the diet more fully, as a result, more of them were excreted in egg products. So, protein with an egg was excreted more by 10.9-13.2%, fat – by 11.4-14.3%, calcium – by 2.3-2.7%, phosphorus – by 3.5-4.2%.

Combined use of ultrasonic and microwave treatment potential evaluation in the meat raw materials defrosting in terms of efficiency and impact on functional and technological properties. Materials and Methods. Defrosting and evaluation of organoleptic and functional-technological properties of meat raw materials samples were performed in conditions of the complex analytical laboratory of Volga Region Research Institute of Manufacture and Processing of Meat-And-Milk Production. Analyses of qualitative characteristics were carried out in accordance with generally accepted methods in the food industry and actual national standards. The objects of the study were frozen samples of lean pork, сhicken breast meat, pork heart, beef liver. Results. In the research, a defrosting meat raw materials method, based on successive processing with microwave fields and ultrasonic vibrations in a solution of sodium chloride was studied. To obtain relevant results, other methods of defrosting frozen meat raw materials used in the food industry were also analyzed. It was found that the combined effect of the microwave electromagnetic field and ultrasonic treatment in an aqueous medium on meat raw materials in all the studied cases has a synergistic effect, thereby increasing the rate of defrosting. In comparison with the immersion method in meat raw materials located in the ultrasound field, moisture accumulation is slower. Supposedly, this occurs due to the hydration processes inhibition on the meat raw materials surface under the effect of ultrasonic cavitation in a liquid. Conclusion. The proposed method of defrosting can be considered promising in terms of reducing weight loss of meat raw materials. At the same time, ultrasonic treatment prevents the accumulation of excess moisture. Soaking in a solution of sodium chloride makes it possible to increase heat transfer and thereby avoid local overheating of the surface, and even increase the power of the microwave electromagnetic field. At the same time, this type of processing leads to a insignificant increase in hardness and darkening of the surface, which limits the raw materials possibilities use.","PeriodicalId":7676,"journal":{"name":"Agrarian-And-Food Innovations","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89758630","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}
