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.

The problem of livestock production that meets sanitary standards in radioactively contaminated territories remains relevant and is of great practical and scientific interest. The use of sorbents from the class of ferrocyanides promotes the production of livestock products (milk) that comply with accepted hygienic standards. The studies were conducted to evaluate the effectiveness of new formulations of feed additives based on potassium–iron (III) hexacyanoferrate (II) (azure iron milori) compared with 137Cs Bifezh sorbent to reduce the content of radiocaesium, on the productivity of dairy cows and qualitative milk indicators. The tests were carried out under production conditions on the basis of the SEC “Rabochii” of the Gordeevsky district of the Bryansk region. The farm was exposed to radioactive contamination as a result of the Chernobyl accident. Agricultural land of the farm is characterized by relatively high pollution densities at 137Сs and high variability. The use of ferrocine-containing preparations as part of new formulations of modified feed additives made it possible to reduce the concentration of 137Cs in cow’s milk by 2–4 times on day 15 and by 4–5 times on day 30 as compared to the control and did not affect the qualitative indicators of cow’s milk, except for a significant increase fat content of milk in all groups of animals by the end of the experiment.

The phosphate industry is one of the biggest polluters of the environment with uranium. Different products are derived after processing phosphoric ore, such as mineral and phosphate fertilizers and phosphate mineral supplements (dicalcium-and monocalcium phosphate) for animal feeding. Phosphate mineral additives used in animal food may contain a high activity of uranium. Research in this study should provide an answer to the extent in which phosphate mineral products (phosphate fertilizer and phosphate mineral feed additives) contribute to the contamination of soil, plants and animals.

Antioxidant Capacities

Heat stress (HS), a nonspecific response to environmental heat, can seriously affect dairy cow health. Feed additives may alleviate HS in dairy cows by improving rumen fermentation efficacy, stimulating feed consumption, enhancing vasodilation, and/or improving antioxidant capacity. The temperature–humidity index (THI) indicates that spring is a non-HS season, and summer is an HS season. HS results in the decrease in dairy cow antioxidant capacities. Our results indicated the decrease in superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT), and total antioxidation (T-AOC) levels and the increase in malondialdehyde (MDA) level during HS season. Meanwhile, antioxidant indexes (SOD, GSH-Px, and T-AOC) were positively correlated with milk yield (p < 0.01), whereas MDA exhibited a significant negative correlation with milk yield (p < 0.05). In addition, the effects of dihydropyridine (DHP) on antioxidant capacity and ruminal microbial communities in dairy cows under HS were investigated. During summer, dairy cows were randomly assigned into two groups under HS, including a standard diet (S-ND) group and standard diet with 3 g/day/cow DHP (S-D) group. DHP treatment significantly restored SOD and GSH-Px levels under HS. Denaturing gradient gel electrophoresis results indicated that the DHP altered ruminal bacterial community mainly composed Proteobacteria and Firmicutes in dairy cows under HS. Our results suggest that DHP can enhance the antioxidant abilities of dairy cows with favorable effects on ruminal microbial communities under HS, further alleviating HS on dairy cows.

Given growing concerns about the use of antibiotics in the treatment of animals, identifying organic alternatives as feed additives to improve animal health and the development of immune responses has become of interest in dairy farming. Humic acids (HA) seem to be a suitable alternative with a favorable impact on the health and production parameters of animals. This study aimed to determine the effects of an HA supplemented diet on milk parameters as well as the effects on somatic cell count (SCC) and the occurrence of mastitis in dairy cows during the peripartum period. Twenty dairy cows in the last stage of pregnancy were selected from a herd of 140 cows. The selected cows were randomly divided into two groups: control (C) and experimental (E). The two groups were fed the same feed mixture and group E was additionally supplemented with HA at a total dose of 100 g per cow per day during the last 50 days of pregnancy. The milk parameters (dry matter, lactose, fat, crude protein, casein and milk urea) and SCC of every cow, and the presence of mastitis, were checked on days 10 and 30 during the first month of lactation. The results of the study show that dietary supplementation with HA significantly reduced the milk urea (MU) content and SCC on the 10th day after calving but did not affect the other milk compositions. In addition to the decreased MU and SCC, the number of positive quarters detected by the California Mastitis Test was reduced by 20.0% and the occurrence of mastitis caused by coagulase-negative staphylococci (CNS). Based on the obtained results we can conclude that the addition of HA stabilizes the nutrient digestion, as was confirmed by a reduced MU content in the supplemented group. Their indirect beneficial effects improved the development of immune responses, resulting in decreased SCC and the occurrence of mastitis caused by CNS.

One of the most industrialized animal production branches of ruminant production successfully requires a blending of theoretical knowledge of nutritional principles with practical stockmanship, maintaining health and dealing with numbers. It is well known that high yielding, dairy cows, require balanced diet with adequate nutrients for yielding. This is not provided with only a few feedstuffs. Milk production in dairy cows is related to the improvements in genetic merit of farm animals and also developments in feed science, feed technology and animal nutrition. In particular, feeds and feed technology studies associated with sustainability, economical perspectives and product quality in the last decade have been in advance. In the present work, recent advances in feed sources and feed technology, minerals (macro and trace minerals ), vitamins and amino acids, feed additives (antibiotics alternative growth stimulants, rumen modulator, organic acids, antioxidants, enzymes, plant extracts), nutrition-products (meat-milk-progeny) quality and functional food production (milk, meat) nutrition-reproduction, nutrition-animal health, nutrition-environmental temperature, nutrition-global warming were evaluated.

The article presents the results of experience in the application of feed additives from local resources in the diets of cows. As a result of the study, the positive effect of using feed additives from local resources in the diets of cows on the digestibility and assimilation of nutrients was proved. The digestibility of cow nutrients was higher in cows of the 2nd experimental group of the formula of feed additives No. 2. Thus, the cows of the 2nd experimental group, who received the recipe of feed additives No. 2 as part of the diet, better digested “raw” protein, fat, and fiber, which served as an additional source of energy for increasing milk productivity. The improvement in the digestibility of most nutrients in the diet is explained by the fact that protein-vitamin-mineral feed additives had a stimulating effect on the state of metabolic processes and the health of animals in general.
