“…This monitoring was carried out in JSC Chervlenoye and JSC Oblomovo of the Svetloyarsky area, which is the most ecologically unsuccessful southern part of a residential suburb of Volgograd. The dynamics of industrial parameters of that period are similar to the current systemic crisis caused by the global, politiсal and economic reasons, and having a tendency to develop further (López-Alonso, 2012). Along with monitoring the livestock production, the quantitative chemical and toxicological analyses were also performed: 30 exemplars of the soil -for 26 indicators; 22 exemplars of water -for 18 indicators; 98 exemplars of forage (26 species of plants) -for 17 indicators; 55 exemplars of blood -for 17 measures; 18 exemplars of wool -for 40 indicators; 34 exemplars of products of slaughter -for 12 indicators; 76 exemplars of milk -for 57 indicators.…”

“…A strict definition of heavy metals and arsenic in sterns of a winter and summer diet of lactic breeds of cattle confirmed that different types of plants possess unequal ability to absorb and accumulate these heavy metals and arsenic, and also lack of a feedforward between the level of pollution and intensity of intake of metals in plants (Zelepukhin, Levahin, 2000;López-Alonso, 2012).…”

Onistratenko N.V., Ivantsova E.A., Denysov A.A., Solodnikov D.A.: Heavy metals in suburban ecosystems of industrial centers and ways of their reducation. Ekológia (Bratislava), Vol. 35, No. 3, p. 205-212, 2016. Technogenic contamination of ecosystems is one of the main dangers of our time. In order to reduce the harmful effects of this contamination and to provide cost-effective and environmentally safe food production methods, we are forced to look for ways of reliable analysis of the environmental situation, the selection systems of animal husbandry and regulations for the degree of impact of pollutants on the elements of the agroecosystem. This article presents the results of studies aimed at assessing the plight of the environment of a large industrial centre, and its anthropogenic impacts on every element of the suburban ecosystems. It presents data on maintenance and migration of anthropogenous pollutants in the trophic chains of pasturable ecosystems of the suburb of Volgograd. The authors have listed the industrial enterprises as the key sources of pollution. The features of the distribution of xenobiotics in the tissues and organs of calves and heifers of different breeds were analysed in the study. Conclusions were drawn on the accumulation of heavy metals and arsenic in cattle, and the impact of this factor on the quality of production. A comparative assessment of the resistance of different breeds of cows to the action of toxicants in the environment of the Lower Volga region was carried out. Ways to decrease the impact of pollutants on the cattle organism have also been suggested. The article pays attention to the environmental pollution of the industrial centre, the influence of these processes on all elements of an ecosystem including humans, and offers ways to minimize the damage.

“…Problems associated with mycotoxins in silage can be minimized by preventing fungal growth before and after ensiling. Proper silage management is essential and must be the first step in preventing/reducing the mycotoxin contamination of dairy cow feeds [55,57]. However, warm and humid weather conditions make it very difficult to control contamination without the use of mold-inhibiting feed additives such as mycotoxin binders used either in the silage or in the Total Mixed Ration (TMR).…”

“…Copper has been related to an increased resistance to mastitis (one of the most relevant problems in dairy farms) [54], particularly that caused by Escherichia coli. López-Alonso [55] reviewed the importance of trace mineral nutrition in organic livestock farming and found that the use of chemical forms of minerals (such as organic minerals/chelates) that are effective in production performance and health must be considered. Trace minerals are chemically bound to a chelating agent or ligand, usually a mixture of amino acids or small peptides.…”

Organic Feed: A Bottleneck for the Development of the Livestock Sector and Its Transition to Sustainability?

There is a current need to increase global livestock production in line with consumers' preferences for more sustainable and 'natural' products. Organic farming is considered among the potential production systems and market strategies that could be employed to cope with this change. Animal nutrition is key, as it greatly influences feed efficiency, animal health, and sustainability. Under situations where animal health care is technically more challenging, due to limitations in the use of veterinary drugs (such as in organic farming), the importance of feed is even higher. However, the there is a lack of commercially available permitted feed ingredients and the range of feed additives on the market is limited. This is partially due to the fact that organic regulations are mainly followed to ensure that pure organic methods are used, instead of trying attain the core goal of complying with organic principles and contributing to the sustainability of the sector. For example, improved animal health and animal welfare through the use of non-organically certified feed additives is needed. This lack of availability, along with difficulties for the feed industry to become organic, affects the development of sustainability in the livestock sector (which should be the final objective of organic farming) in both already organic livestock/feed companies and those still producing under the conventional system. In this context, the presented work may be interesting to producers and policymakers, as it is aimed at providing a critical view of the relationship between the market and the needs of the livestock sector, the sustainability challenge, and organic farming regulations as applied to animal nutrition.

“…Hence, selenomethionine is absorbed and metabolized relative to methionine needs. If selenomethionine is broken down within the cell, Se is released and recognized by the cell as a mineral [29]. It is then processed according to the need for Se.…”

Selenium Biochemistry and Bioavailability: Implications for Animal Agriculture

Selenium (Se) is an essential trace mineral required for growth, development, immune function, and metabolism. Selenium exerts its biological effects as an integral component of selenoproteins (SePs). Deficiency or low Se status leads to marked changes in many biochemical pathways and a range of pathologies and disorders which are associated with SeP function. Animals, and presumably humans, are able to efficiently utilize nutritionally adequate levels of Se in both organic and inorganic forms. It is now clear that the bioavailability of Se varies depending on the source and chemical form of the Se supplement. There are a range of products available for dietary Se supplementation, however, organic sources have been shown to be assimilated more efficiently than inorganic compounds and are considered to be less toxic and more appropriate as a feed supplement. Yeast enriched with Selenohomoalanthionine (SeHLan) has recently become commercially available, and initial research suggests that it may be an efficacious source for the production of Se enriched animal products.
