Pacific Dulse Protein: A Promising Source of Bioactive Peptides

Abstract Objectives Pacific dulse (Devaleraea mollis) is a protein-rich seaweed in the Pacific Northwest and increasingly being cultivated as food resource. Our previous work showed that dietary supplementation of dulse exerted beneficial metabolic effects to the high-fat fed mouse model. This study aims to evaluate the potential of the seaweed protein from dulse as a precursor for bioactive peptide (BAP) generation. Methods The potential of Pacific dulse protein as BAP precursor was assessed using in vitro and in silico approaches. Hydrolysates were prepared from the hydrated freeze-dried protein isolates which were digested using commercial proteases. These were used for the in vitro screening for antioxidant and anti-inflammatory activities as well as the inhibition of Angiotensin-converting enzyme 1 (ACE-1), Renin, and Dipeptidyl peptidase IV (DPPIV). Peptides in the hydrolysates that exhibit the highest activities were identified using de novo sequencing. Identified peptides were shortlisted based on their potential to be bioactive using Peptide Ranker and specific bioactivity scores were obtained using in silico platforms such as iDPPIV-SCM and PreAIP. To determine whether the consumption of the seaweed protein may help give rise to some bioactive peptides, annotated protein sequences of the seaweed material were obtained from UniProtKB and were subjected to in silico digestion using pepsin, chymotrypsin, and trypsin through BIOPEP. Bioactivity indices of the generated peptide fragments were recorded as predictive values. Results In silico digestion showed that dulse proteins can give rise to ACE-1, DPP-IV, and renin inhibitors, as well as antioxidant peptides. Hydrolysates exerted inhibitory effects on human ACE-1, DPPIV, and renin in vitro. ABTS radical scavenging assay and cellular antioxidant activity assay in human hepatocytes indicated the strong antioxidant potential of dulse BAP. Peptides identified through de novo sequencing had high predictive scores for DDPIV inhibition and anti-inflammatory potential. Conclusions Pacific dulse proteins is a promising precursor for the generation of BAPs that may exert beneficial health activities and support metabolic health improvement.

Effectiveness of Integrated Weed Management Practices on Dry Matter Production and Crop Nutrient Uptake in Machine Transplanted Rice

A field experiment entitled “Weed management in machine transplanted rice” was conducted during kharif season, 2019 at Agricultural Research Institute Farm, Professor Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad to evaluate the influence of different weed management practices on growth and nutrient uptake machine transplanted rice crop. The results revealed that among different weed management treatments hand weeding at 20, 40 DAT (T8) recorded significantly higher dry matter production at harvest (14.7 t ha-1) which was at par with T4 i.e. penoxsulam 1.02% W/W + cyhalofop-p-butyl 5.1% W/W @ 153 g ha-1 at 2-3 leaf stage of weeds + power weeder at 30-40 DAT (14.3 t ha-1). Hand weeding at 20, 40 DAT had significantly increased the crop nutrient uptake at harvest (147.0: 16.9: 153.6 NPK kg ha-1), statistically at par with penoxsulam 1.02% W/W + cyhalofop-p-butyl 5.1% W/W @ 153 g ha-1 at 2-3 leaf stage of weeds + power weeder at 30-40 DAT (142.6: 16.0: 145.4 NPK kg ha-1) while lowest was recorded with weedy check (91.9: 9.9: 89.2 NPK kg ha-1).

Quantifying the Nitrogen Requirement of Castor Cultivars in Post Monsoon Season on Alfisols

Aim: The experiment is aimed at quantifying the nitrogen requirement and identifying suitable hybrids and varieties of castor to be grown during post monsoon season on Alfisols in Telangana
 Study Design: Split plot design.
 Place and Duration of Study: Regional Agricultural Research Station, Professor Jayashankar Telangana State Agricultural University, Palem, Telangana state, India during post monsoon season of 2010-11 and 2011-12.
 Methodology: The study consisted of four N levels (0, 40, 80 kg and 120 kg N ha-1) in main plots and five cultivars (DCH-177, PCH-111, GCH-4, Haritha and 48-1)in sub plots. The growth parameters, yield attributes, seed yield, water use efficiency, economic returns, correlation and regression were studied.
 Results: The pooled data indicated that significantly taller plants with more no. of branchesplant-1, longer and effective spikes thus seed yield of castor were observed due to application of 80 kg Nha-1 and 120 kg Nha-1. However, application of 120 kg N ha-1 resulted in greater net returns (USD 1049 ha-1) and also returns per rupee invested (1.66). The results further showed that the castor hybrids PCH-111 (1900 kg/ha) and DCH-177 (1809 kg/ha) produced similar yield, but, both significantly outyielded over other cultivars. The performance of hybrids was superior to the varieties. A highly significant positive correlation was observed for seed yield with no. of branches/plant, total and effective spike length.
 Conclusion: The cultivation of castor hybrids either PCH-111 or DCH-177 under N supply of 120 kg N ha-1 would help to realize higher yields, water use efficiency and income from post monsoon season castor on Alfisols.

Integration of Virtual Programming into Beef Cattle Producer and Extension Agent Education

Field days and workshops are fundamental to fostering communication and demonstrating management techniques. However, when faced with the COVID-19 pandemic, Extension agents turned to alternative platforms for providing educational opportunities. In April 2020, Louisiana State University Agricultural Center (LSU AgCenter) agents hosted a live webinar entitled “Sustainability during Turbulent Markets” to bring beef cattle producers information on management strategies during a time of instability. This initial webinar included 41 live participants and an additional 40 views within one week of posting the recording. Event responses prompted creation of the Beef Brunch Educational Series, an online series designed to maintain engagement and allow agents to present timely management recommendations and industry news to producers. Live webinars occur at 10:30 a.m. on the second Tuesday of each month. Webinars are also recorded for online distribution through the LSU AgCenter website, LSU AgCenter-Livestock YouTube channel, and podcast platforms. Bi-weekly news updates are released on the same platforms. News updates feature weather and pasture conditions, market outlooks, management tips, events, and current industry topics. Webinar engagement on all platforms averages 233 viewers with a growth range of 81 to 859 since April. News updates average 87 views with a growth range of 29 to 270 participants. When asked, 85% of viewers strongly agreed or agreed that information learned in webinars would be applied to their operations. Extension agents utilize this program for professional development, with 75% strongly agreeing or agreeing that webinars increased confidence to apply presented knowledge and 70% stating they have or plan to incorporate news update content in their programming. Thus, increased views, positive feedback, and requests for more information illustrate relevance in continuing the Beef Brunch Educational Series beyond the COVID-19 pandemic and optimistically developing it into a leading informational source for beef cattle producers in Louisiana.

Mixture interactions of quizalofop and reduced rates of halosulfuron

AbstractA field study was conducted in 2017 and 2018 at the Louisiana State University Agricultural Center H. Rouse Caffey Rice Research Station near Crowley, LA, to evaluate the impact of reduced rates of halosulfuron on quizalofop activity in Louisiana rice production. Halosulfuron and a prepackaged mixture of halosulfuron plus thifensulfuron were evaluated at 0, 17, 35, or 53 g ai ha−1 and 34 or 53 g ai ha−1, respectively, in a mixture with quizalofop at 120 g ai ha−1. Control of barnyardgrass, red rice, and two non-acetyl-CoA carboxylase resistant rice lines, CL-111 and CLXL-745, were recorded at 14 and 28 d after treatment (DAT). The red rice, CL-111, and CLXL-745 represented a weedy rice population. Across all species evaluated at 14 DAT, all mixtures containing halosulfuron and halosulfuron plus thifensulfuron resulted in antagonism with an observed control of 79% to 90%, compared with an expected control of 96% to 99%. At 28 DAT, all mixtures containing halosulfuron resulted in neutral interactions for barnyardgrass control. Quizalofop mixed with halosulfuron plus thifensulfuron at the lower rate of 34 g ha−1 was able to overcome the antagonism compared with the higher rate of 53 g ha−1 for barnyardgrass control at 28 DAT. Both the high and the low rate of halosulfuron plus thifensulfuron resulted in antagonistic interaction for red rice, CL-111, and CLXL-745 control at 28 DAT. This research suggests that mixing quizalofop with halosulfuron plus thifensulfuron should be avoided, especially at the higher rate of 53 g ha−1.

Agro-economic Feasibility and Indices of Castor+Groundnut Intercropping System Under Irrigated Conditions During Rabi Season in Telangana

An experiment was carried out for three consecutive years from 2014-15 to 2016-17 at Regional Agricultural Research Station (RARS), Palem, Professor Jayashankar Telangana State Agricultural University, Telangana, India to study and understand the agro-economic feasibility and various indices of castor+groundnut intercropping system under irrigated conditions during rabi season. There were six treatments viz., sole castor, sole groundnut, castor+groundnut (1:5) with RDF (recommended dose of fertilizer) to both the crops, castor+groundnut (1:7) with RDF to both the crops, castor+groundnut (1:5) with RDF to castor alone and castor+groundnut (1:7) with RDF to castor alone. The results indicated that sole groundnut with significantly higher castor equivalent yield (3960 kg ha-1) gave a higher yield advantage by 12.5 to 25.8% over castor+groundnut intercropping and 102.5% over sole castor. Further, sole groundnut recorded higher water use efficiency (10.25 kg ha-1 mm-1) and net returns mm-1 water used (Rs. 243.65 mm-1). The economics also indicated that sole groundnut was profitable in terms of gross (Rs. 1,50,465 ha-1) and net returns (Rs. 94,150 ha-1). However, higher benefit:cost ratio was observed with sole castor (2.76) followed by sole groundnut (2.67) and castor+groundnut intercropping (1:5) with RDF applied to both crops (2.57). Among various indices, the highest land equivalent ratio (1.13), area time equivalency ratio (1.00) and monetary advantage index (15072) were recorded with castor+groundnut (1:5) where RDF was applied to both the crops.

Barley is cultivated mainly for feed purposes in the Tyumen region. At the same time, there is a need to obtain brewing barley grain. This research is aimed at establishing the influence of elements of cultivation technology on the productivity of barley varieties and identifying the compliance of grain quality indicators with the established requirements. The studies were performed in three field experiments on the experimental field of the of the Northern Trans-Ural State Agricultural University in the northern forest-steppe of the Tyumen region in 2014 - 2016. In terms of the complex indicator – the collection of protein from a unit area – the Lamador Pro + Rostok variant stood out: for the Acha variety, this indicator was 612 kg/ha, for the Abalak variety - 646 kg/ha. The best indicators were obtained in the variant with the use of Hydromix complex for treating the seeds: for the Acha variety, the yield was 4.55 t/ha, for the Abalak variety - 4.62 t/ha, the protein content in the grain was 13.1 and 13.3%, respectively. In terms of yield, Omsky 85, Payjazz and Beatrice varieties surpassed the standard. The obtained research results are recommended for implementation at the enterprises of the agro-industrial complex of the Tyumen region.

BIOTECHNOLOGY OF PRODUCTION OF YEAST-FREE BREAD USING THE LOCAL STREPTOCOCCUS THERMOPHILUS STRAIN BREEDED BY GORSK GAU AND WILD HOP IN RNO-ALANIA

The modern food industry offers the consumer bread baked with sourdough using various biologically active components of plant origin. In the production of yeast-free bread, it is advisable to use a sourdough from biologically active strains of Streptococcus thermophilus selected by the Gorsk State Agricultural University. The authors have compiled a starter culture from local strains of lactic acid microorganisms selected by the Research Institute of Biotechnology of the Gorsky State Agrarian University. Research was carried out at the Department of Biological and Chemical Technology of the Gorsky State Agrarian University. We also used cones of wild-growing hops from the botanical garden of the Gorsky State Agrarian University in order that the bitter acids present in the hops suppress the putrefactive microflora, do not have a detrimental effect on local strains of lactic acid microorganisms and allow increasing the productivity of the hop starter culture. Yeast-free bread is easily absorbed by the body, does not harm the intestinal microflora, retains useful properties during storage. The flour used in the experiment met the requirements of GOST 26574–85. When using wild-growing hops in the production of bread, useful substances included in its composition were determined that could increase the quality and safety of bread. The content of alpha acids was 6.0%, and that of essential oils was 0.7%, which corresponds to GOST 32912–2014. We used two strains of a lactic acid microorganism of local selection – Streptococcus thermophilus. Hops were extracted for 30 min at a temperature of 96 °C. Laboratory baking of bread was carried out in accordance with GOST 27669–88. Studies have shown that bread prepared using a local strain of Streptococcus thermophilus selected by the Gorsky State Agricultural University and wild-growing hops is of high quality.

Perception of the Farmers regarding Constraints Faced during Farmers’ Fair

Famers’ fair an important tool in transferring latest technologies to farmers is gaining momentum over the years. The main purpose of organizing such farmers’ fair is to create awareness among visitors about new technologies developed by researchers primarily from the government sector, agricultural and allied research centres and State Agricultural Universities (SAUs). Considering its importance, an exploratory study was carried out to identify the constraints perceived by the visiting farmers and remedies suggested by them for improvement of farmers’ fair. The present study was conducted at Chaudhary Charan Singh Haryana Agricultural University (CCS HAU), Hisar main campus during 2019-20. Empirical data were collected through personal interview technique with the help of well-structured and pre-tested interview schedule and analyzed using standard methodology. Findings revealed that infrastructural constraints were perceived highest with composite index value (CIV) of 38.28, followed by physical (34.37), institutional (30.00), miscellaneous (19.27) and social (07.81) constraints. With regards to suggestions, most of the farmers suggested time duration of farmers’ fair should be increased followed by adequate transport facilities, seeds should be made available at low price, etc. Hence, the paper recommends that although the farmers’ fairs are playing an effective role in information dissemination but must be updated each year to catch more attention of the farmers.

Complex evaluation of calendula officinalis flowers by main biologically active substances content

Relevance. The demand for medicinal raw materials of Calendula officinalis L. is determined by the high content of pharmacologically significant compounds. Comparison of the most common ornamental cultivars of Calendula officinalis L.) in terms of yield and content of biologically active substances in the raw material helps to identify the most promising cultivars in terms of a set of indicators.Materials and methods.The decorative cultivars Apricot, Art Shads, Fiesta Gitana, Kabluna golden-yellow, Orange King, Orange Balls, Yellow Gitana and Golden Balls, characterized by large inflorescences and terry, were used as prototypes. The cultivar Kalta, widely used for the production of medicinal raw materials, was chosen as a control. The experiments were laid on the experimental plots of the Fruit Growing Laboratory of the Russian State Agricultural University – Moscow Timiryazev Agricultural Academy. Productivity was determined as the total weight of inflorescences harvested during the entire season per unit area. The amount of flavonoids was determined by spectrophotometry. The amount of polysaccharides was determined according to the modified Draywood method. The lutein content was determined by HPLC.Results.To obtain inflorescences we can recommend to use the variety Orange King, which, with a satisfactory yield (0.363 kg/m2), was characterized by a high content of flavonoids (1.2%) and satisfactory (35.9%) extractives and corresponds to the quality of raw materials required by GF XIV. In addition, this variety was characterized by an increased content of polysaccharides (20.3%). The Varieties Apricot and Yellow Gitana were characterized by high productivity (562±49 and 507±41 g/m2, respectively). Their raw materials can be used by production of herbal teas, where the content of flavonoids is not regulated. As sources of lutein, one should pay attention to the ligulate flowers of the varieties Apricot, Fiesta Gitana, Golden balls. In the variety Kabluna, with the maximum lutein content, the proportion of reed flowers in the inflorescence was only 38%. In varieties with large inflorescences, the content of lutein in reed flowers was higher (R=0.685). Large non-double inflorescences will be most productive in this indicator.

Genetic Variability for Yield and Its Related Traits in Green gram [Vigna radiata (L.) Wilczek

Background: Green gram [Vigna radiata (L.) Wilczek] is an ancient and well known pulse crop of Asian countries. Specific traits should be considered for high yield in green gram as selection criteria in future breeding program.Methods: The investigation material comprised of 128 F6 RIL (Recombinant Inbred LINE) population sown at college farm, Professor Jayashankar Telangana State Agricultural University during Rabi-2019-20. The yield and yield attributes were recorded to conduct genetic variability, heritability broad sense (h2), genetic advance (GA) and genetic advance as % of mean (GAM).Result: Analysis of variance revealed significant differences among the RILs, indicating the presence of genetic variability for almost all the traits studied. High PCV and GCV estimates was noticed for number of pods per plant, seed yield per plant, number of cluster per plant and number of pods per cluster. High heritability along with high genetic advance as per cent of mean was observed for number of pods per plant, seed yield per plant, number of cluster per plant, number of pods per cluster, number of branches per plant, number of seeds per pod and plant height indicating the role of additive genes in governing the inheritance of these traits and could be improved through selection. The traits viz. seed yield per plant, number of pods per plant, number of clusters per plant and number of pods per cluster had recorded high PCV, GCV, high heritability along with high genetic advance as per cent of mean indicated these traits were less influenced by environment and possess high genetic variability. Hence these RILs would be suitable for green gram breeding programmes to develop improved varieties. The present findings of the RIL population will be useful for development of high seed yielding variety in green gram.

Protein concentrates based on extruded lupine grain, with the use of enzymes, in feeding calves and poultry

The solution to the food security of the population of any region depends on the creation of its own production of high-protein plant feeds. Protein nutrition issues need to be addressed quickly, both in protein production and in rational use. Unbalanced diets for protein inhibits the growth and development of young animals, disrupts metabolism, increases feed consumption per unit of production, thereby increasing its cost. Under these conditions, the use of non-traditional protein feeds of local production and the creation of new recipes for energy-protein concentrates as full-fledged components of compound feeds has become one of the tasks of the Kaliningrad research Institute of agriculture-a branch of the Federal research center all-Russian Institute of feed named after V. R. Williams.The author has been working on the problem of protein deficiency since 2000. She started at the Federal state unitary enterprise “Novonikolaevskoe” in the Balakovsky district of the Saratov region with scientists from the Department of animal feeding at the Vavilov state agricultural University: doctors of agricultural Sciences Alexander Petrovich Korobov, Sergey Petrovich Moskalenko, Alexey Alekseevich Vasiliev, and continued from 2009 to the present at the Kaliningrad research Institute of agricultural research.The article presents data on feeding calves (2013-2019) and quails (2019) energy-protein concentrate based on extruded grain of narrow-leaved lupine, instead of soy, subjected to heat treatment on a press extruder as part of compound feed; determining the effect of the concentrate on changing the productivity of calves and quails. Calves were fed lupine concentrate with a shell, quails without a shell with the addition of an enzyme preparation.It was found that the feed value of the extruded concentrate based on lupine is not inferior to the extruded concentrate based on soy and allows you to get good gains in live weight of animals and poultry. Concentrate based on lupine, with the addition of enzymes in biological value is equal to full-fat soy.

Interactions of clomazone plus pendimethalin mixed with propanil in rice

AbstractA study was conducted at the Louisiana State University Agricultural Center’s H. Rouse Caffey Rice Research Station in 2017 and 2018 to evaluate the interaction between a prepackage mixture of clomazone plus pendimethalin applied at 0, 760, 1,145, or 1,540 g ai ha−1 mixed with propanil at 0, 1,120, 2,240, or 4,485 g ai ha−1. A synergistic response occurred when barnyardgrass was treated with all rates of clomazone plus pendimethalin mixed with either rate of propanil evaluated at 56 d after treatment (DAT). Unlike barnyardgrass, an antagonistic response occurred in yellow nutsedge used as a control when treated with 760 and 1,540 g ha−1 of clomazone plus pendimethalin mixed with 1,120 or 22,40 g ha−1 of propanil at 28 DAT; however, 1,145 g ha−1 of clomazone plus pendimethalin mixed with 4,485 g ha−1 of propanil resulted in a neutral interaction. At 28 DAT, rice flatsedge treated with all herbicide mixtures resulted in neutral interactions. The synergism of clomazone plus pendimethalin applied at 1,540 g ha−1 mixed with propanil applied at 2,240 or 4,485 g ha−1 to control barnyardgrass resulted in an increased rough rice yield compared with 760 or 1,145 g ha−1 of clomazone plus pendimethalin mixed with propanil applied at 1,120 or 2,240 g ha−1. These results indicate that if barnyardgrass and rice flatsedge are present in a rice field the prepackage mixture of clomazone plus pendimethalin mixed with propanil can be an option for growers. However, if yellow nutsedge infest the area other herbicides may be needed.

МОРФОЛОГИЯ МЫШЕЧНОЙ ТКАНИ ЦЫПЛЯТ-БРОЙЛЕРОВ ПРИ ЗАМЕНЕ В КОРМЕ АНТИБИОТИКОВ НА БИОЛОГИЧЕСКИ АКТИВНУЮ ДОБАВКУ

This paper discusses the outcomes of the production experiment carried out on one of the poultry farms in the Sverdlovsk Region and at the departments of the Ural State Agricultural University. The experiment was carried out on cross Ross-308 broiler chickens in the number of 80 female and 80 male chickens with an average live weight of 43 g. During the research, the chickens were housed in different cages; the experiment continued throughout the entire rearing period - 38 days. The control group formed of comparable chickens was fed with the basic diet used on the farm with the nutritional value required for this cross, and during rearing, from the 1st to 10th day, the Albac feed antibiotic (500 g per t) was administered; it was substituted with Fortrazin (600 g t) from the 11th to 30th day. From the first day of rearing to the end of fattening, the trial group received the basic diet but the antibiotic was substituted with an alternative safe growth promoter SafMannan in the amount of 0.5 kg per t of compound feed. Comparative zootechnical indices of the control and trial groups showed that the introduction of the SafMannan supplement into the compound feed did not affect the chicken survival rates, and had a promoting effect on the growth and development of broilers accompanied by live weight gains. Histological examination of the breast and thigh muscle groups of the control and trial chickens did not reveal any pathological processes neither with the addition of feed antibiotics or with the introduction of the biologically active supplement SafMannan; the muscle mass increased due to young un-differentiated muscle fibers that were in the process matu-ration, but the final differentiation of the entire muscle mass by the end of the technological cycle did not occur.

The modern pace of development and perspectives of horticulture in Azerbaijan

The Republic of Azerbaijan has all the conditions, both natural and socio-economic, for the development of horticulture. Over the last decade, the gross harvest of vegetables has been growing steadily. By 2018, it was 1522 thousand tons. The yield of vegetables has also grown in the indicated period from 14.7 to 21.9 t/ha. Vegetables occupy 4800 ha of a protected ground. The production of greenhouse vegetables targets the Russian market. The bottleneck of this sector is the breeding of vegetable seeds. This market, with a capacity of almost 20 million Euro, is occupied by foreign companies. At the same time, agricultural producers get help from the state in the form of subsidies, preferential credits, and full tax exemption. The research in the sector is also developing. We can note such possible developments as the renovation and outfitting of the Research Institute for Horticulture as well as the training of horticulturists in the Azerbaijan State Agricultural University. The further development of the sector continues in the way of the intensification and biologization of production, the improvement of the range and quality of products.

ПОВЫШЕНИЕ ДОЛГОВЕЧНОСТИ ЗАЩИТНЫХ ПОКРЫТИЙ МАШИН И ОБОРУДОВАНИЯ АПК НАНО МОДИФИЦИРОВАННЫМИ ЛАКОКРАСОЧНЫМИ МАТЕРИАЛАМИ

This paper discusses the current areas of work to en-sure the performance of protective coatings for machinery and equipment in theagricultural industry complex for the conditions of Siberia. The following five main areas were identified: corrosion protection, thermoregulation, fire re-sistance, antistatics and radiation protection. It was found that the most efficient way to ensure the performance of coatings is their nanomodification. The method of fire re-sistance tests developed at the Novosibirsk State Agricul-tural University is presented. The results of preliminary tests in two areas are presented: fire resistance and corro-sion protection. One of the promising nano-additives is bismuth oxide which may improve fire resistance and phys-ical and mechanical properties. According to the research results, when the concentration of bismuth oxide reaches 5%, an extremum is observed for the values of hardness (86-94) and adhesion (3.3-3.6 MPa) of the coating. At the same time, the addition of bismuth oxide in a concentration of 7.5% made it possible to achieve a significant increase in the fire resistance of the coating. Fire resistance and ignition time increased to 240°C and 65 s, respectively. Some of the most effective additives are identified and the further direction of the study is indicated which consists in optimizing the compositions of protective coatings and providing a set of properties for operating conditions in each specific case. It is also necessary to take into account the combined effect of nanomodifiers on the properties of the protective coating.

РАЗРАБОТКА ТЕХНОЛОГИИ ВАРЕНЫХ КОЛБАСНЫХ ИЗДЕЛИЙ С ИСПОЛЬЗОВАНИЕМ БАРАНИНЫ

The article is devoted to the development of the technology of boiled sausages using lamb. Lamb occupies a special place in the diet of the population of the Southern Federal District. Sheep meat is a valuable type of meat that is a priority in ensuring the country's food security. Mutton, compared to the meat of other animals, contains less cholesterol, and mutton in its characteristics can be attributed to dietary products. Due to the fact that lamb is characterized by high food and taste qualities, the demand of the population for its processed products has recently increased. Currently, there is an increase in the use in the production of meat products of animal protein preparations isolated from collagen-containing raw materials. High functional and technological properties of such preparations, especially water-binding and gel-forming properties, make it possible to significantly improve the rheological properties of food products-consistency, as well as organoleptic characteristics and enrich meat products with food fibers. Experimental studies were carried out in the laboratory of the Department of Food Technology and Commodity Science of the Don State Agricultural University. On the basis of the conducted studies, a recipe and a technological scheme for the production of boiled sausages using lamb were developed. The feasibility of using a collagen module in a meat product is justified. The prospects and feasibility of using collagen raw materials in the production of meat products are determined by a number of positive aspects, including the expansion of the raw material base of the meat industry, enrichment of products with analogues of food fibers and economic feasibility. Dose of introduction of collagen module into product and optimal method of use is established. On the basis of organoleptic and physicochemical studies, a rational formulation of the product is proposed.
