The results of studies to determine the optimal level of input of a complex of macronutrients in protein-vitamin-mineral supplements are given, their influence on digestibility, the use of feed nutrients, hematological parameters, growth and development of young pigs are studied. Feeding in the composition of grain-cereal rations of 12.5% protein-vitamin-mineral supplements with elevated levels of Fe, Cu, Zn, Mn, Co, J, Se contributes to an increase in pigs by 5.5-8.5% of daily gains, by 8-12 days of early maturity, by 0.28-3.35% slaughter yield, by 12.1-19.5% meat ratio. Bringing microelements to the optimum level in protein-vitamin-mineral supplements composition contributes to a significant increase in the digestibility of organic matter and raw fat. Reducing the level of trace elements by 30% hinders the process of digestion of feed. The use of 12.5% protein-vitamin-mineral supplements with a high content of trace elements in grain-cereal rations of pigs has a significant effect on the degree of utilization of nitrogen, calcium, phosphorus, iron, copper, zinc, manganese. When protein-vitamin-mineral supplements are fed with an optimal level of trace elements in the composition of diets of young pigs, it contributes to an increase in the number of erythrocytes, hemoglobin, total protein and its fractions. A 30% increase in the level of trace elements in protein-vitamin-mineral supplements provides for obtaining high-energy meat with a high content of dry matter, protein and fat. The inclusion in the composition of grain-cereal rations of protein-vitamin-mineral supplements with the optimal level of trace elements helps to reduce the cost of feed by 5.2-7.8%, to obtain 3.8 kg of additional growth.

This study aimed (1) to assess serum trace elements concentrations and hematological parameters, (2) to evaluate the sex differences in the associations between serum trace elements levels and hematological parameters, and (3) to identify the associations between serum trace elements concentrations and risk of anemia among Japanese community dwellers. This is a community-based cross-sectional study that utilized the data of the 2014 Iwaki Health Promotion Project. Participants were 1176 community dwellers (>18 years) residing in the Iwaki District, Aomori Prefecture, Japan. We assessed the data of serum trace elements concentrations of cadmium (Cd), cobalt (Co), copper (Cu), selenium (Se), zinc (Zn), and iron (Fe) as well as the hematological parameters of red blood cells (RBC) counts, hemoglobin, packed cells volume (PCV), mean corpuscular volume (MCV), and mean corpuscular hemoglobin (MCH). Serum concentrations of Zn (871.5 μg/L vs. 900.1 μg/L) and Fe (946.8 μg/L vs. 1096.1 μg/L) were significantly lower in females than in males, while serum concentrations of Co (0.4 μg/L vs. 0.3 μg/L) and Cu (1062.4 μg/L vs. 965.3 μg/L) were significantly higher in females. By multivariate linear regression, serum Se concentration was significantly, positively associated with PCV (β = 1.04; 95% confidence interval (CI): 0.17, 1.92; p = 0.016) among the study participants. Serum Zn also had positive associations with hemoglobin (β = 0.42; 95% CI: 0.07, 0.77; p = 0.020), PCV (β = 1.79; 95% CI: 0.78, 2.81; p < 0.001), and RBCs count (β = 15.56; 95% CI: 7.31, 31.69; p = 0.002). On the other hand, serum Co concentration was negatively associated with the hematological parameters, particularly in females. Moreover, serum Zn concentration had a decreased risk of anemia (lowest vs. highest quartiles: odds ratio (OR) = 0.42; 95% CI: 0.23, 0.76; p = 0.005) while higher Co concentrations had an increased risk of anemia (lowest vs. highest quartiles: OR = 1.95; 95% CI: 1.04, 3.67; p = 0.037). However, no significant association was found between serum Cu level and hematological parameters. There were substantial sex differences in serum trace elements, implying that trace elements metabolism differed between males and females. Zn can play a protective role in the development of anemia. Surprisingly, increased Co concentration increased the risk of anemia among our study population, which called for further studies to confirm and to consider for speciation analysis.

Purpose. To study the effectiveness of feeding different levels of mixed-ligande complex of zinc, manganese and cobalt with Suplex Se to high-yielding cows of the Ukrainian red-spotted dairy breed in the first period of lactation and their impact on feed consumption, productivity and hematological parameters of blood. Methods. Five groups (one control and four experimental) of highly productive cows of the Ukrainian red-spotted dairy breed, 10 heads each, were selected for the research at «Terezyne» farm, Bila Tserkva district, Kyiv region, on the principle of analogues. Experimental cows were fed the same rations. For cows of the control group the optimal dose of a mixed-ligande complex of Zinc, Manganese and Cobalt was used, which was established in a previous experiment with concentration in 1 kg of dry matter (DM) of feed, mg: zinc – 60.8; manganese – 60.8 and cobalt – 0.78. In the 2nd experimental group, concentration of those trace elements was higher compared to the control by 10%, and in the 3rd, 4th and 5th experimental groups, respectively, 10, 20 and 30% lower. Results. The best results in terms of milk productivity were obtained from cows of the 4th experimental group. For 80 days of the experiment from cows of the 1st control group 3080 kg of milk of natural fat content was obtained, and of the 2nd, 3rd, 4th and 5th experimental groups – respectively 48, 112, 200 and 136 kg, or by 1.6; 3.6; 6.5 and 4.4% more. Lower doses of micronutrients meet the needs of highly productive cows in them, which has a positive effect on the reproductive functions of animals. The most effective was the dose for the cows of the 4th experimental group, where duration of the service period was 78.6 days against 91.9 days in the 1st control group, and one fertile insemination in this group took 1.8 times at 3.1 times in control. Analysis of hematological parameters of the experimental cows shows that different levels of mixed-ligande complexes of zinc, manganese and cobalt in concentrated feeds have a positive effect on the body and health of lactating cows. Conclusions. The best results of milk productivity and reproductive function were obtained from cows of the 4th experimental group, where concentration of zinc, manganese and cobalt due to their mixed-ligande complexes in 1 kg of DM feed was, mg: zinc – 42.6; manganese – 42.6; cobalt – 0.55. This dose of trace elements had a positive effect on the consumption of animal feed, their unit cost and hematological parameters of cows' blood.
