Fodder Production

The ecological conditions of fodder production and agricultural technology for the cultivation of fodder resources have a great influence on the characteristics in the chemical composition and nutritional value of local fodders, determines their yield and the economic aspect of production. The Amur Region belongs to a biogeochemical region with a sharp deficiency in the biosphere of a number of normalized macro-and microelements vital for animals. In this regard, mineral supplements and premixes for animals and poultry imported from other regions can be not only useless, but even harmful. In order to determine the need for feeding with minerals, you need to know which chemical elements are contained in feed and in the diet in insufficient quantities, and which in excess. Along with this, the normalized microelements introduced into the composition of feed and rations in the form of mineral salts are poorly digested by all types of animals. It is most effective to feed them in combination with organic nutrients. In this regard, the purpose of the experimental research was to study the possibility of using feed additives made from local non-traditional feed resources in feeding cattle. As a result of scientific, economic and physiological (balance) experiments, the effectiveness of using feed additives made from local fodder resources in feeding cattle for growth, metabolism and milk productivity was determined.

AbstractThe rearing of piglets is the most difficult period in the pigs’ production because of their poorly developed digestive system and the low activity of digestive enzymes. Problems in nutrition and stress cause some disorders in the functioning of the digestive system leading to diarrhea and the mortality of piglets. Starting in 2006 in the EU, a total ban on antibiotics in their use as growth promoters was introduced. Since then, new and safe feed additives have been sought in order to replace antibiotics. Organic and inorganic acids as well as their salts were recognized as effective and safe additives. Due to their properties, they can improve feed palatability and digestibility, reduce the buffer capacity of feed, impact the development and functioning of the pig’s digestive system and improve the health and growth parameters. However, the effectiveness of acids is related to their qualitative and quantitative share in the feed additive. In this review, some strategies for using organic acids, their mixtures and also some new multi-component products will be discussed.

Mineral Feed Additives

Animals imported to Yakutia from other regions fall into feeding and housing conditions that differ from their usual agro-climatic conditions, which causes the problem of their adaptation. Yakutia is one of the areas where the feed of its own production has a lack of basic minerals, which affects the health and productivity of animals, which has an additional negative influence on the adaptation process of imported cattle. In order to replenish macro- and microelements in the body, it is necessary to introduce various local mineral feed additives, premixes, and use mineral salts into the ration. Under the conditions of Central Yakutia the influence of local mineral feed additives (zeolite of the Khonguruu Deposit in the Suntar district and sapropels of local lakes) containing macro- and microelements that increase the meat productivity of steers has been studied. As a result of the research the influence of local mineral feed additives on meat productivity and physiological condition of Hereford steers has been established. Influence of zeolite and sapropel in a complex with mineral salts on digestibility of nutrients of the ration and use of nitrogen, calcium and phosphorus by experimental animals has been defined. The influence of feed additives on the quality of meat products has been studied. The results have shown that the use of local mineral feed additives in the composition of ration of steers during the fattening period at a dose of 0,7 g zeolite per 1 kg of live weight of the animal and 200 g of sapropel in combination with 10 g of mineral salts contributed to the gain in live weight, carcass weight, carcass yield, yield of edible parts, and economic efficiency of fattening. For the entire period of the experiment the gain in live weight in groups was: in control group 2222,9 kg, in the 1st experimental group 2396,2 kg, in the 2nd experimental group 2471,1 kg. The total economic effect for the 1st experimental group for the period of experiment amounted to 44,3 thousand Rubles, for the 2nd experimental group 78,0 thousand Rubles or per 1 head/day 14,06 and 24,76 Rubles, respectively.

Изучена целесообразность использования в рационах телят черно-пестрой породы комплексной минерально-витаминной кормовой добавки (КМВКД). Установлено пониженное содержание в кормах таких элементов, как кальций, фосфор, магний, сера, марганец, медь, цинк и кобальт. Соотношение питательных и минеральных веществ, степень их доступности для усвоения организмом не обеспечивают их потребность. Использование КМВКД способствовало улучшению всех гематологических показателей. Все испытываемые рецепты, имеющие в своем составе разные варианты макро-, микроэлементов и витаминов положительно влияют на обменные про- цессы в организме животных. У молодняка опытной группы, получавшей подкормку по рецепту 1, количество эритроцитов в сравнении с животными контрольной группы увеличилось на 6,6, гемоглобина на 6,93 соответственно, по рецепту 2 11,05 и 11,39 по рецепту 3 16,75 и 15,27, то есть соотношение макро- и микроэлементов, имеющихся в составе КМВКД и взаимодействие между собой меди, железа и кобальта сыграли особую роль на концентрацию форменных элементов. У молодняка, получавшего подкормку по рецепту 1 количество общего белка в сравнении с животными контрольной группы увеличилось на 1,99, кальция на 16,02, каротина на 10,92 соответственно, по рецепту 2 4,91, 25,96 и 19,12 по рецепту 3 на 3,58, 27,07 и 20,21. Значительное повышение содержания белка, кальция, фосфора и каротина по сравнению с животными контрольной группы объясняется тем, что недостаток их в рационах восполнялся за счет используемой подкормки, в результате их содержание увеличилось в сыворотке, но не выходило за пределы нормативных данных и соответствовало физиологическим нормам.Practicability of using a complex mineral and vitamin feed additive (CMVFA) in the ration of black-and-white calf breed was studied. Decreased content of such elements as calcium, phosphorus, magnesium, sulfur, manganese, copper, zinc, and cobalt was registered. The correlation of nutritive and mineral substances, and the level of their availability for digestion did not provide for their need. CMVFA use facilitated the increase of all hematologic parameters. Tested recipes which had different content of sapropel and zeolite, as well as various types of macronutrients, microelements, and vitamins, positively influenced the digestive processes in animal bodies. Young stock from the test group that was receiving food additives according to recipe No. 1 showed 6.6 increase in the quantity of red blood cells compared to control group animals, and 6.93 increase in hemoglobin quantity the ones who were fed according to recipe No. 2 demonstrated the increase by 11.05 and 11.39 recipe No. 3 showed 16.75 and 15.27 increase, which means that the ratio of macronutrients and microelements present in CMVFA and the mutual interaction of copper, iron, and cobalt played a special role in the concentration of formed elements due to the fact that they are integral elements of blood. Total protein of young stock that was receiving food additives according to recipe No. 1 was 1.99 higher than in test group animals calcium 16.02 higher carotene 10.92 as for recipe No. 2 the values were increased by 4.91, 25.96, and 19.12 recipe No. 3 3.58, 27.07, and 20.21. Substantial increase in the content of protein, calcium, phosphorus, and carotene compared to control group animals can be explained by the fact that their insufficiency in animal feed was replenished due to the use of feed additives, and as a result their content increased in the serum but did not go beyond the norm and corresponded to physiological norms.

ABSTRACTWe have been investigating modulation strategies tailored around the selective stimulation of the host's immune system as an alternative to direct targeting of microbial pathogens by antibiotics. One such approach is the use of a group of small cationic peptides (BT) produced by a Gram-positive soil bacterium,Brevibacillus texasporus. These peptides have immune modulatory properties that enhance both leukocyte functional efficiency and leukocyte proinflammatory cytokine and chemokine mRNA transcription activitiesin vitro. In addition, when provided as a feed additive for just 4 days posthatch, BT peptides significantly induce a concentration-dependent protection against cecal and extraintestinal colonization bySalmonella entericaserovar Enteritidis. In the present studies, we assessed the effects of feeding BT peptides on transcriptional changes on proinflammatory cytokines, inflammatory chemokines, and Toll-like receptors (TLR) in the ceca of broiler chickens with and withoutS. Enteritidis infection. After feeding a BT peptide-supplemented diet for the first 4 days posthatch, chickens were then challenged withS. Enteritidis, and intestinal gene expression was measured at 1 or 7 days postinfection (p.i.) (5 or 11 days of age). Intestinal expression of innate immune mRNA transcripts was analyzed by quantitative real-time PCR (qRT-PCR). Analysis of relative mRNA expression showed that a BT peptide-supplemented diet did not directly induce the transcription of proinflammatory cytokine, inflammatory chemokine, type I/II interferon (IFN), or TLR mRNA in chicken cecum. However, feeding the BT peptide-supplemented diet primed cecal tissue for increased (P≤ 0.05) transcription of TLR4, TLR15, and TLR21 upon infection withS. Enteritidis on days 1 and 7 p.i. Likewise, feeding the BT peptides primed the cecal tissue for increased transcription of proinflammatory cytokines (interleukin 1β [IL-1β], IL-6, IL-18, type I and II IFNs) and inflammatory chemokine (CxCLi2) in response toS. Enteritidis infection 1 and 7 days p.i. compared to the chickens fed the basal diet. These small cationic peptides may prove useful as alternatives to antibiotics as local immune modulators in neonatal poultry by providing prophylactic protection againstSalmonellainfections.

Abstract Recent research has demonstrated that swine viruses can be transmitted via feed. Chemical feed additives have been suggested for the mitigation of these viruses in complete feed. Therefore, the objective of this study was to evaluate the efficacy of a commercially available formaldehyde-based feed additive, medium chain fatty acid blend (MCFA), and commercially available fatty acid-based products for mitigation of porcine epidemic diarrhea virus (PEDV) and porcine reproductive and respiratory syndrome virus (PRRSV) in a feed matrix. Treatments consisted of: 1) non-treated positive control, 2) 0.33% commercial formaldehyde-based product (Sal Curb; Kemin Industries, Inc.; Des Moines, IA), 3) 0.5% MCFA blend (1:1:1 ratio of C6:0, C8:0, and C10:0, Sigma Aldrich, St. Louis, MO), 4) 0.25%, 5) 0.5%, or 6) 1% of commercial dry mono and diglyceride-based product (Furst Strike; Furst-McNess Company, Freeport, IL), 7) 0.25%, 8) 0.5%, or 9) 1% of commercial dry mono and diglyceride-based product (Furst Protect; Furst-McNess Company, Freeport, IL), 10) 0.25%, 11) 0.5%, or 12) 1% dry mono and diglyceride-based experimental product (Furst-McNess Company, Freeport, IL) with 3 replications/treatment. Treatments were applied to complete swine feed before inoculation with 106 TCID50/g of feed with PEDV or PRRSV. Post inoculation feed was held at ambient temperature for 24 h before being analyzed via qRT-PCR. The analyzed values represent the cycle threshold. Formaldehyde and MCFA decreased (P < 0.05) the detectable RNA of PEDV and PRRSV compared to all other treatments. Furst Strike, Furst Protect, and the experimental product did not significantly impact detectability of PEDV or PRRSV RNA. In conclusion, MCFA and formaldehyde treatments are effective at reducing detection of RNA from PEDV and PRRSV in feed.

The effectiveness of forest resources depends on the comprehensiveness and rationality of their consumption and processing into finished products. This article discusses the problem of using solid fir wood greenery residues generated during the industrial production of essential oils. Bioconversion is considered to be the most promising use. The objective of this research was to study the chemical composition of bioconversion products of fir wood greenery-based substrates. The РР-3.2 strain of Pleurotus pulmonarius (Fr.) Quél was used as a biodestructor. In the process of bioconversion, the contents of polysaccharides and lignin substances is reduced to 38% and 28%, respectively. Up to 20% of protein accumulates in bioconversion products of fir wood greenery. The amount of nucleic acids is not more than 1.5 g per kg; the contents of heavy metals, such as mercury, cadmium, arsenic, and lead, do not exceed the maximum permissible concentration standards. The substrate weight loss reaches 15%. When fallen leaves and post-extraction poplar bud residues are added to the substrate, the substrate-destroying activity of fungi increases, and the protein content increases by 3%. The digestibility of products as a result of bioconversion increases 1.6–2.8 times depending on the substrate composition. The obtained data support the recommendation of post-fermented substrates based on fir wood greenery and balsam poplar biomass for use as a protein feed additive.

Modern domestic feed production is developing at a fairly steady pace, which is facilitated by the increase in the volume and scale of production in the livestock sector. Today, domestic agricultural pro-ducers fully provide the domestic market with pork, poultry and egg. the efficiency of the development of the livestock sector depends on the quality of feed and the fattening system by more than 60%. All this proves the relevance and prospects of studying the dynamics of the development of feed production in order to im-prove the manageability of this area of management, organizational support, identify potential risks and de-velop effective solutions to minimize them. As the basic provisions of the study, it is worth noting: key produc-tion segments of the domestic feed industry; production volumes of mixed feeds, premixes, feed additives and concentrates in Russia; market leaders in the production of mixed feeds at the time of 2019.; the reasons for the transition of large companies to self-feed; the negative factors (risks) which impact on sustainable devel-opment of the Russian market of animal feed; scenarios of development of domestic fodder production in the short term (2–3 years) taking into account the most pressing problems and uncertainties (distribution COVID-19; higher prices for imported feed additives; devaluation; grain yield; volatility of prices for raw materials and components, logistics, etc.); substantiation of the prospects for the development of the Russian food complex against the background of the strengthening of the global problem of hunger and food security.
