“…However, in the present study, the concentrations of Cu and Mn in the control treatment were lower (1.3 and 8.7 mg/kg, respectively) than those in previous studies (Bossolani et al, 2020;Brennan et al, 2008;Min et al, 2022) in which Fe dominated due to the strong acidity of the soil (Truog, 1947). These differences are attributable to variations in soil types; for example, the study by Bossolani et al (2020) was conducted in tropical agricultural soil, whereas this study was conducted in a temperate semi-natural grassland.…”

Lime application (liming) has historically been used to ameliorate soil acidity in grasslands. Liming effectively improves soil pH, plant productivity, and soil physicochemical properties, but the long-term impact of acidity control by liming on key microbial nitrogen (N)-cycling genes in semi-natural grasslands is unknown. We investigated the effect of 65 years of liming on N-cycling processes in the limed and control plots of the Ossekampen long-term grassland experiment in the Netherlands. These plots have not received any other fertilizers for 65 years. Soil sampling and nitrous oxide (N2O) emission measurements were conducted three times in spring and four times in summer, and quantitative real-time PCR was performed to determine the abundances of N-cycling genes, including ammonia-oxidation (amoA), denitrification (nirS, nirK, nosZ), and N-fixation (nifH) genes. Long-term liming increased the abundances of nitrifiers and denitrifiers but did not increase N2O emissions. Additionally, liming had a buffering effect that stabilized the population of N-cycling microbes against seasonal variations in abundance. Our results indicate that improving soil acidity through liming facilitates microbial N-cycling processes without increasing N2O emissions.

“…In Ca supplement treatment, there were no significant differences observed in serum AST, ALT, ALB, and T-Bil when compared with Ca deficiency treatment, which may suggest that the dietary Ca supplementation for 41 days failed to alleviate liver damage or dysfunction. In the research, it was indicated that the Cu deficiency in Kazakh sheep caused a significant increase in ALT and AST activities, which resulted in hepatocyte damage ( 13 ). The same results were also found in the sheep serum in the Cu deficiency group.…”

“…The deficiency of dietary Zn often results in the loss of appetite, metabolic disorders, and the reduction of hemoglobin concentrations ( 12 ). Cu is widely found in various enzymes and cofactors, especially in the liver ( 13 , 14 ). In some research, it is revealed that copper deficiency causes reproductive disorders and alters the immune response of ruminants ( 15 ).…”

Traditional sheep grazing is the pillar industry and the main source of income for local herders in the Inner Mongolia Autonomous Region of China. However, grazing sheep often suffer from mineral deficiency. In the present study, the feeding experiment was performed on 84 grazing Wu Ranke sheep. After being divided into calcium (Ca), zinc (Zn), copper (Cu), cobalt (Co), manganese (Mn), and selenium (Se) treatment groups, they were fed with a mineral deficient diet for 60 days and then a mineral supplement diet for 41 days. Serum samples were collected three times, 10 concentrations of essential mineral elements and 15 concentrations/activity of biochemical parameters were measured to assess the effects of mineral deficiency and supplementation on the physical health of sheep. The results revealed that the sheep showed mineral Ca, Cu, Co, Mn, and Se deficiencies after feeding their respective mineral deficient diet. Deficiency in dietary Ca, Zn, Cu, Co, Mn, and Se may adversely affect the liver, myocardium and pancreas of sheep. The prompt supplementation of dietary Zn, Cu, Co, Mn, and Se may alleviate the damage caused to the liver, myocardium and pancreas, while that of dietary Ca improved energy generation. In conclusion, the adequate supplementation of dietary Ca, Zn, Cu, Co, Mn, and Se is essential for avoiding the impairment caused to the liver, myocardium and pancreas function of sheep by the deficiency in essential dietary minerals.

“…Металлотионеины могут связывать ионы меди и переводить их в редокс-неактивное состояние (Calvo J et al, 2017). Вызванное дефицитом меди снижение активности цинк-медьсодержащей супероксиддисмутазы у животных задокументировано в ряде современных исследований (Wu T et al, 2020;Ergaz Z et al, 2018;Min X et al, 2022). Церулоплазмин является металлопротеином, содержащим медь, он участвует в метаболизме железа и во многих окислительновосстановительных реакциях (Bakhautdin B et al, 2014).…”

https://orcid.org/0000-0003-3717-4533Аннотация. Баланс между свободными радикалами и антиоксидантами является основополагающим звеном для правильного физиологического функционирования организма. Однако при нарушении условий жизнедеятельности происходит срыв антиоксидантной системы защиты, что ведёт к чрезмерному увеличению продукции активных форм кислорода и процессов свободнорадикального окисления. Для нормальной работы антиоксидантной системы важно постоянство химического состава. Несмотря на небольшое содержание, микроэлементы необходимы для нормального функционирования организма благодаря их разнообразной биологической роли. Гомеостаз ряда микроэлементов лежит в основе динамического взаимодействия между окислительным стрессом и антиоксидантами во многих патофизиологических процессах. Как дефицит, так и избыток микроэлементов может влиять на окислительно-восстановительный баланс. В настоящем обзоре представлены краткие сведения о природе, типах и источниках свободных радикалов, а также роли селена, цинка, меди и железа в работе антиоксидантной системы защиты.Ключевые слова: окислительный стресс, активные формы кислорода, антиоксиданты, селен, цинк, медь, железо Благодарности: работа выполнена при поддержке Российского научного фонда, проект № 22-25-00600.
