Zinc, Copper, and Manganese Homeostasis and Potential Trace Metal Accumulation in Dairy Cows: Longitudinal Study from Late Lactation to Subsequent Mid-Lactation. J Nutr 2023; 153:1008-1018. [PMID: 36813237 DOI: 10.1016/j.tjnut.2023.02.022] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 01/09/2023] [Accepted: 02/09/2023] [Indexed: 02/23/2023] Open
Abstract
BACKGROUND Trace metals are supplemented in cattle to prevent nutrient deficiencies. Levels supplemented to mitigate worst-case basal supply and availability scenarios can, however, result in trace metal intakes far above the nutritional requirements of dairy cows with high feed intakes. OBJECTIVES We evaluated Zn, Mn, and Cu balance in dairy cows from late lactation through the subsequent mid-lactation, a period of 24 wk characterized by large changes in dry matter intake. METHODS Twelve Holstein dairy cows were housed in a tie-stall from 10 wk before to 16 wk after parturition and fed 1 unique lactation diet when lactating and a dry cow diet otherwise. After 2 wk of adaptation to the facility and diet, Zn, Mn, and Cu balances were determined at weekly intervals, by calculating the difference between total intakes and complete fecal, urinary, and milk outputs, with the latter 3 fluxes quantified over a 48-h period. Repeated measure mixed models were used to evaluate the effects on trace mineral balances over time. RESULTS The Mn and Cu balances of cows were not significantly different from 0 mg/d between 8 wk prepartum and calving (P ≥ 0.54), when dietary intake was the lowest of the period evaluated. However, when dietary intake was highest, between wk 6 and 16 postpartum, positive Mn and Cu balances were observed (80 and 20 mg/d, respectively, P ≤ 0.05). Cows were in positive Zn balance throughout the study except during the first 3 wk after calving during which the Zn balance was negative. CONCLUSIONS Large adaptations occur in trace metal homeostasis in transition cows in response to changes in dietary intake. High dry matter intakes, associated with high milk production of dairy cows, combined with current Zn, Mn, and Cu supplementation practices may exceed regulatory homeostatic mechanisms resulting in potential body accumulation of Zn, Mn, and Cu.

Abstract
Copper (Cu) and selenium (Se) are antioxidants and essential trace elements that have mutual interaction and are reported to have beneficial effects at supranutritional levels. The experiment was executed to evaluate the individual impact of supranutritional levels of targeted elements with the effect of their interactions in buffalo calves. Twenty male Murrah buffalo calves of about 8-9 months (bodyweight 112.1 ± 7.69 kg) were distributed into four groups of five calves in each group and fed either a control (C) diet or supplemented with supranutritional levels of Cu (T1), Se (T2), or combination of both (T3) for 120 days. Higher (P = 0.015) values of packed cell volume were observed in group T2 at day 120; otherwise, all other hematological parameters remained comparable among groups. Over the period (day 120 vs. day 0), an enhancement in the percentage of lymphocytes (P = 0.006) with a reduction in neutrophils (P = 0.028) and hemoglobin (P = 0.024) values was observed in the control group. An enhancement in the percentage of monocytes (P = 0.031), with a reduced percentage of neutrophils (P = 0.022), was reported in groups T2 and T3, respectively. Interaction of Cu and Se at supranutritional level (T3) dramatically reduced plasma Cu (P = 0.008) level against the control values, with an improvement in Se markers (i.e., plasma Se, P = 0.041 and enzyme glutathione peroxidase, P = 0.057) over the values in calves fed supplemental Se alone (T2). Additionally, Cu (T1 and T3) was forced to decline (P < 0.05) Zn level in the plasma of buffalo calves. Cu (T1, P < 0.05) and Se (T2 and T3, P ≤ 0.01) supplementation was able to improve their respective plasma levels. The interaction of two trace elements at the supranutritional level further helped in reducing the lipid peroxidation (P = 0.01) values as well. Though antioxidant vitamins and cell-mediated immunity remained unaffected, humoral immunity against antigen P. multocida was high (P = 0.005) in the group T2. The conclusion may be drawn that supranutritional Cu and Se were capable to influence certain blood parameters with an additional interaction effect due to simultaneous supplementation in buffalo calves.

Abstract
Protein production from animal origin should increase to meet the needs of a growing global population. This article presents an overview on copper (Cu) forms and their importance for animals' physiological functions. Moreover, it will focus on the current and promising nano-Cu applications in poultry, livestock, and fish production systems. Use of Cu as a feed additive directly or indirectly impacts the human food chain and may affect the safety and/or quality of food. Finally, the expected risks and hazards related to the use of nano-Cu that can affect animals, humans, and the environment are described. It is concluded that nano-Cu applications have the potential to provide an efficient solution for reducing the Cu amount in the poultry, livestock, and fish diets, which can help in reducing costs and environmental contamination and increasing animals' productivity. However, concerns over the safety of nano-Cu applications hamper their immediate implementation. Thus, rigorous risk assessments should be conducted to ensure the safety of animal-origin products in the case of supplementation animal diets with nano-copper.

Abstract
Ensuring adequate copper supplementation in ruminants is a challenging task due to the complexity of copper metabolism in these animals. The three-way interaction between copper, molybdenum and sulphur (Cu-Mo-S) in the rumen makes ruminants, particularly cattle, very susceptible to suffering from secondary copper deficiency. Paradoxically, excessive copper storage in the liver to prevent deficiency becomes a hazard when ruminants are fed copper-supplemented diets even slightly above requirements. While cattle were traditionally thought to be relatively tolerant of copper accumulation, and reports of copper poisoning were until recently somewhat rare, in recent years an increased number of episodes/outbreaks of copper toxicity in cattle, particularly in dairy cattle, have been reported worldwide. The growing number of lethal cases reported seems to indicate that copper intoxication is spreading silently in dairy herds, urging the development of strategies to monitor herd copper status and improve farmers' awareness of copper toxicity. In fact, monitoring studies carried out on numerous samples collected from culled animals in slaughterhouses and/or diagnostic laboratories have demonstrated that large numbers of animals have hepatic copper concentrations well above adequate levels in many different countries. These trends are undoubtedly due to copper supplementation aimed at preventing copper deficiency, as dietary copper intake from pasture alone is unlikely to cause such high levels of accumulation in liver tissue. The reasons behind the copper overfeeding in cattle are related both to a poor understanding of copper metabolism and the theory of "if adding a little produces a response, then adding a lot will produce a better response". Contrary to most trace elements, copper in ruminants has narrow margins of safety, which must also be formulated considering the concentrations of copper antagonists in the diet. This review paper aims to provide nutritionists/veterinary practitioners with the key points about copper metabolism in cattle to guarantee an adequate copper supply while preventing excessive hepatic copper loading, which requires à la carte copper supplementation for each herd.

Abstract
ABSTRACT: Copper is an essential micromineral in animal feed; however, when consumed in excess, it can cause liver necrosis, hemolytic crisis, hemoglobinuric nephrosis and death in cattle. Although uncommon in this species, copper poisoning occurs as a result of exacerbated supplementation, deficiency of antagonist microminerals, or previous liver lesions. An outbreak of chronic copper poisoning is reported in semi-confined cattle after supplementation with 50 mg/Kg of dry matter copper. The cattle showed clinical signs characterized by anorexia, motor incoordination, loss of balance, jaundice, brownish or black urine, diarrhea and death, or were found dead, 10 to 302 days after consumption. Of the 35 cattle that died, 20 underwent necropsy, whose frequent findings were jaundice, enlarged liver with evident lobular pattern, black kidneys, and urinary bladder with brownish to blackish content. Microscopically, the liver showed vacuolar degeneration and/or zonal hepatocellular centrilobular or paracentral coagulative necrosis, in addition to cholestasis, mild periacinal fibrosis, apoptotic bodies, and mild to moderate mononuclear inflammation. Degeneration and necrosis of the tubular epithelium and intratubular hemoglobin cylinders were observed in the kidneys. Copper levels in the liver and kidneys ranged from 5,901.24 to 28,373.14 μmol/kg and from 303.72 to 14,021 μmol/kg, respectively. In conclusion, copper poisoning due to excessive nutritional supplementation is an important cause of jaundice, hemoglobinuria, and death in semi-confined cattle.

Effects of Super Nutritional Hepatic Copper Accumulation on Hepatocyte Health and Oxidative Stress in Dairy Cows. Vet Med Int 2019; 2019:3642954.

Abstract
Concerns regarding excessive hepatic copper concentrations in dairy cows have increased. The objective of this study was to determine the association of hepatic copper concentrations with evidence of liver disease. Blood and liver samples were collected at the time of slaughter in cull dairy cows (n=100). Liver samples were analyzed for copper using inductively coupled plasma mass spectrometry and crude fat using liquid-liquid extraction and gravimetry. Serum samples were analyzed for glutamate dehydrogenase, γ-glutamyltransferase, sorbitol dehydrogenase, aspartate aminotransferase activities, and bile acid concentrations. Liver samples were examined histologically for inflammation, fibrosis, and rhodanine staining. Animals were stratified by hepatic copper concentration and samples in the highest and lowest quintiles (Q5 and Q1) were evaluated for oxidative stress. Systemic indices of oxidative stress included serum reactive oxygen and nitrogen species (RONS) and total antioxidant potential (AOP). Tissue-level oxidative stress was assessed by immunohistochemistry using 4-hydroxynonenal (4HNE) and 3-nitrotyrosine (3NIT) stains to score the relative abundance and distribution of oxidized lipid and protein products, respectively. Mean hepatic copper concentration was 496.83 μg/g and median 469.72 μg/g and ranged from 70.56 to 1264.27 μg/g dry tissue. No association was found between hepatic copper concentrations and clinicopathological or histological evidence of hepatic damage or dysfunction. There was a significant increase in the amount of IHC staining of 4HNE and 3NIT in Q5 compared with Q1. Moreover, the IHC staining mirrored the distribution of the copper-specific stain rhodanine. These results demonstrate that cows with elevated hepatic copper concentrations had no evidence of active liver disease but had increased hepatic oxidative stress.

Abstract
There has been some recent criticism about the reliability of the assays commonly used to measure oxidant status in cattle, because some recent publications suggested that the concentration of different trace elements influences the results of these assays. The aim of this study was to test the correlation in 502 bovine serum samples between the concentration of several trace elements (Br, Co, Cr, Cu, Fe, I, Mn, Mo, Ni, Se, Sr, V and Zn) and markers of oxidant status (reactive oxygen species (ROS) and total serum antioxidant capacity (SAC)). The Oxidative Stress index (OSi) was also calculated as ROS/SAC. Some significant correlations were found, although weak (|ρ| < 0.50). Therefore, the relationships observed might be attributed to the different pro- and antioxidant effect of the different elements rather than to the assays detecting these elements instead of the oxidised molecules or total antioxidant potential, respectively. The OSi was poorly correlated (|ρ| ≤ 0.36) with the concentration of the studied trace elements, and therefore, its use is recommended to assess shifts in the systemic redox balance.

Abstract
The aim of this study was to evaluate essential and toxic element concentration of ten commercially available veal cuts, together with diaphragm, cardiac muscle and liver tissue from 10 animals of "Galician Supreme Veal". Essential trace elements (Co, Cr, Cu, Fe, Mn, Mo, Ni, Se and Zn) and toxic elements (As, Cd, Hg and Pb) were determined by ICP-MS. Essential trace element concentrations ranged from 0.002-55.64mg/kg between muscles. Toxic element concentrations were very low, and high numbers of samples showed unquantifiable residues of Cd and Pb. Veal cuts including muscles with a high proportion of oxidative slow-twitch fibers (diaphragm and cardiac muscle) showed significantly higher essential trace element concentrations, the lower concentrations being found in veal cuts including glycolytic fast-twitch fibers (eye round). Our results suggest that essential and toxic trace element concentration could be used as a new meat quality parameter, or to add further value to certain products (i.e. livestock reared on extensive systems with high physical activity).

Abstract
The present study investigated the effects of dietary trace mineral (Cu, Fe, Mn, and Zn) supplemental strategies on liver oxidative stress, endoplasmic reticulum stress, inflammation, and apoptosis of pigs. A total of 96 Duroc × Landrace × Yorkshire (DLY) piglets were randomly divided into four groups: considered or not considered the trace mineral concentrations in basal diet, and then added to the requirements proposed by NRC (2012) (+B/NR or -B/NR); and considered or not considered the basal diet's trace mineral concentrations and then added to the level of commercial trace mineral supplement (+B/PL or -B/PL). Pigs were fed from 6.5 to 115 kg. Compared with +B/NR diets, -B/PL diets increased serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) concentrations (P < 0.05), resulted in high levels of Fe, Cu, Mn, and Zn accumulation in liver (P < 0.05), as well as led to hepatic oxidative damage with the high concentrations of thiobarbituric acid reactive substance (TBARS), protein carbonylation (PCO), and 8-hydroxyguanine (8-OHG) in liver (P < 0.05). Furthermore, pigs fed -B/PL diets increased CCAAT/enhancer-binding protein homologous protein (CHOP), eukaryotic initiation factor-2α (eIF-2a), interleukin-6(IL-6), B-cell lymphoma leukemia-2-associated X protein (Bax), and caspase-3, caspase-8, and caspase-9 gene expression (P < 0.05) in liver. -B/PL diets also up-regulated hepatic mRNA expression of phosphoenolpyruvate carboxykinase1 (PEPCK1), glucose-6-phosphatase (G6PC), acetyl-CoA carboxylase (ACC), fatty acid synthase (FAS) (P < 0.05) and down-regulated hormone-sensitive lipase (HSL) mRNA expression (P < 0.05) when compared with those of the + B/NR diet group. Taken together, the results indicated that long-term dietary mineral exposure with the commercial supplement level could cause harm to the structure and metabolic function of liver in pigs.

Abstract
We studied pathways of apoptosis regulation during experimental hepatopathy caused by treatment with antitubercular drugs and involvement of some hepatoprotectors and immunomodulators in the regulation of hepatocyte apoptosis induced by antitubercular drugs. The intensity of apoptosis and expression of apoptosis-associated molecules were evaluated. It was shown that antitubercular drugs induce apoptosis in hepatocytes by triggering external signaling pathway and p53-dependent signaling pathway and simultaneously reducing the level of anti-apoptotic Bcl-2 protein. Runihol, remaxol, and cycloferon reduced degenerative effects in the liver, though the level of apoptosis remained high. Ademetionine in tablets and reamberin improved the microstructure of the liver by inhibiting both apoptotic pathways induced by the antitubercular drugs; in other words, they have distinct hepatoprotective and apoptosis-protective effects, which is especially important at the late stages of ontogeny.

Abstract
The new approaches of the animal production systems make managing the mineral nutrition a challenge. Versus the excessive, trace mineral supply in intensively managed livestock, well above the physiological requirements, is the no trace mineral supplementation of organic systems, which become highly dependent on trace minerals in the soil. Nowadays, in addition to the animal health perspective, trace mineral nutrition must be environment friendly and allow getting mineral-enriched animal products. We are in a new scenario, where a balance between animal trace mineral needs and limits is needed. This papers focuses on different aspects that will help us to enter a critical dialogue in relation to animal-human-environment.
