[PMID: 38322168 PMCID: PMC10845341 DOI: 10.3389/fvets.2024.1301852] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 01/08/2024] [Indexed: 02/08/2024] Open
Abstract
Objective The objective of this study was to investigate the impact of dietary deficiency and supplementation of calcium, zinc, copper, cobalt, manganese or selenium on minerals content in the longissimus dorsi (LD), biceps femoris (BF) and triceps brachii (TB) of grazing Mongolian sheep. Methods We randomly divided 98 sheep into 7 treatment groups and fed them specific diets for 60 days: a total mineral nutrition diet (LCG), a calcium deficiency diet (LCa), a zinc deficiency diet (LZn), a copper deficiency diet (LCu), a cobalt deficiency diet (LCo), a manganese deficiency diet (LMn) and a selenium deficiency diet (LSe). Then 7 sheep from each group were slaughtered and samples of LD, BF and TB were collected for mineral content analysis. The remaining sheep in each group were subsequently fed specific diets for an additional 41 days: a total mineral nutrition diet (SCG), a calcium supplementation diet (SCa), a zinc supplementation diet (SZn), a copper supplementation diet (SCu), a cobalt supplementation diet (SCo), a manganese supplementation diet (SMn) and a selenium supplementation diet (SSe). Afterward, all sheep were slaughtered, and muscle samples were collected and analyzed. Results Significant findings emerged that LCa decreased sulfur (S) content in BF and increased Ca content in LD and BF, while SCa increased S and Ca content in BF and TB, respectively (P < 0.05). LZn decreased Zn, S, and potassium (K) content in LD and BF, while SZn increased Zn and S content in LD and BF, respectively (P < 0.05). LCu decreased Cu and iron (Fe) content in LD and TB, while SCu increased Fe content in TB (P < 0.05). LCo decreased phosphorus, S, K, Ca, Mn, Fe, Cu, and Zn content in LD (P < 0.05). LMn decreased Mn content and increased K content in TB, while SMn decreased K content in BF and TB (P < 0.05). LSe and SSe decreased and increased Se content in LD, BF, and TB, respectively (P < 0.05). Conclusion Dietary mineral levels have varying effects on lamb meat minerals content. It is important to ensure an adequate intake of minerals in the diet to enhance the mineral nutrition of lamb meat.

Abstract
Kazakh sheep are vital to the production system of the Barkol prairie. The purpose of this study was to determine the effect of nano-copper oxide (Nano-Cu2O) on the antioxidant system of Cu-deficient Kazakh sheep in the Barkol prairie in Xinjiang, China. We analyzed mineral contents in soil, forage, and animal tissues. Blood parameters were also measured at the same time. The results showed that compared with healthy grassland, the Cu content in the soil and forage in Cu-deficient pastures was significantly lower than that in healthy grassland (P < 0.01). The Cu content in the blood, wool, and liver of Cu-deficient Kazakh sheep was significantly lower than that of healthy animals (P < 0.01). After Kazakh sheep were supplemented with Nano-Cu2O or CuSO4, the blood Cu concentration increased significantly (P < 0.01). From the 5th day, the Cu content of the Nano-Cu2O group was significantly higher than that of the CuSO4 group. The levels of hemoglobin (Hb), erythrocyte count (RBC), and packed cell volume (PCV) in the two experimental groups were significantly higher than those in Cu-deficient Kazakh sheep (P < 0.01). Compared with Cu-deficient Kazakh sheep, the serum ceruloplasmin (Cp) level of the two experimental groups increased significantly (P < 0.01), while the serum lactate dehydrogenase (LDH), alkaline phosphatase (AKP), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) decreased significantly (P < 0.01). Compared with Cu-deficient Kazakh sheep, the activities of serum superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT), and total antioxidant capacity (T-AOC) in Nano-Cu2O and CuSO4 groups increased significantly (P < 0.01), while the level of serum malondialdehyde (MDA) decreased significantly (P < 0.01). Therefore, Nano-Cu2O could not only significantly increase the Cu content in the blood of Cu-deficient Kazakh sheep, but also greatly improve the antioxidant capacity.

Abstract
The experiments were to study the effects of Se-yeast on immune and antioxidant in Selenium(Se)-deprived Pishan red sheep in Southern Xinjiang, China. The samples of soil, forage, and animal tissues were collected, and used for measuring mineral content, physiological parameter, and biochemical values. These findings showed that the Se contents in affected soil and forage were markedly lower than those from unaffected soil and forage (P < 0.01). Se in affected blood and wool were also extremely lower than those from healthy Pishan red sheep (P < 0.01). The hemoglobin, packed cell volume, platelet count, Glutathione peroxidase, and total antioxidant capacity in the affected Pishan red sheep were markedly lower than those from healthy ones too (P < 0.01). The levels of malondialdehyde, total nitric oxide synthase, and lipid peroxide in Pishan red sheep from affected pastures were extremely higher than those from healthy ones (P < 0.01). The levels of interleukin (IL)-1β, Interleukin-2, tumor necrosis factor-α and interleukin-6 from serum were markedly decreased in affected Pishan red sheep(P < 0.01). The Pishan red sheep in Se-deprived pasture were treated by orally with Se-yeast, the amount of Se in the blood markedly increased in treated animals. Meanwhile, the immune and antioxidant indicator was returned to the healthy values. Consequently, our findings were indicated that Se-deprived forage caused oxidative damage, and a serious threat to the immune function in animals. The Se-yeast is more effective in the Se-deficient Pishan red sheep including blood Se content, immune function and the antioxidant capacity.

Abstract
Tibetan gazelle (Procapra picticaudata) is an endangered ungulate in the Qinghai-Tibet Plateau, China. This study aimed to determine the influence of nano-Se on antioxidant system in Se-deprived P. picticaudata. We analyzed contents of mineral elements in soil, forage, and animal tissue. Blood parameters and antioxidant indexes were also determined. The results showed that Se concentrations in the soil and forage from affected pasture were significantly lower than those in healthy area (P < 0.01). Se concentrations in blood and hair from affected P. picticaudata were also significantly lower than those in healthy animals (P < 0.01). Meanwhile, the levels of Hb, RBC, and PCV in affected gazelle were significantly lower than those in healthy animal (P < 0.01). The activities of AST, ALT, LDH, CK, and UA content in affected animal were significantly lower than those in healthy gazelles (P < 0.01). The levels of SOD, GSH-Px, CAT, and T-AOC in serum were significantly lower and the MDA content was significantly higher in affected compared with healthy gazelle (P < 0.01). Affected P. picticaudata were treated orally with nano-Se, Se concentration in blood significantly increased and serum antioxidant indexes greatly returned to within the healthy range. Consequently, nano-Se could not only markedly increase the Se content in blood in Se-deprived P. picticaudata but also much improves the antioxidant capacity.

Abstract
To research responses of Chinese Merino Sheep (Junken type) to copper-deprived natural pasture, we analyzed mineral contents in soil, forage, and sheep tissues. Physiological and biochemical parameters were also determined. Results showed that copper concentrations in soil and forage from affected pastures were significantly lower than those in healthy ranges (P < 0.01). Copper contents in animal tissues (blood, liver, and wool) from affected Chinese Merino Sheep were also significantly lower than those in healthy sheep (P < 0.01). Hemoglobin levels, packed cell volume, mean corpuscular volume, and mean corpuscular hemoglobin from affected Chinese Merino Sheep were significantly lower than those in healthy animals (P < 0.01). Serum ceruloplasmin was significantly lower in affected Chinese Merino Sheep than that in healthy animals, while activities of lactate dehydrogenase, alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase in serum were significantly higher in affected compared with healthy animals (P < 0.01). The levels of superoxide dismutase, glutathione peroxidase, total antioxidant capacity, and catalase in serum were significantly lower, and the malondialdehyde content was significantly higher in affected compared with healthy sheep (P < 0.01). The levels of interleukin-2, interleukin 6, interleukin-1β, immunoglobulin A, immunoglobulin M, and immunoglobulin G in copper-deprived sheep were significantly lower than those in healthy animals (P < 0.01). Copper deprivation in forage not only influenced the mineral content in blood but also severely disrupted blood parameters (physiology, biochemistry, immunity, and antioxidant) in Chinese Merino Sheep.

Abstract
To study responses of Procapra przewalskii to zinc (Zn) nutrition in physical habitat, we analyzed the content of mineral elements in soil, forage, and animal tissues. Physiological and biochemical indexes were also determined. The results showed that Zn contents in the soil and forage from affected pasture were significantly lower (P < 0.01) than those in unaffected areas. Zn concentrations in the blood, liver, and hair from affected P. przewalskii were also significantly lower (P < 0.01) than those in healthy animals. The levels of hemoglobin, erythrocyte count, and packed cell volume from affected P. przewalskii were significantly lower (P < 0.01) than those in healthy animals. Serum aspartate aminotransferase and alanine transaminase activities were significantly lower (P < 0.01) in affected P. przewalskii than in healthy animals, while serum lactate dehydrogenase and alkaline phosphatase levels were significantly higher (P < 0.01) in affected compared with healthy animals. The activities of superoxide dismutase, glutathione peroxidase, and catalase in serum were significantly lower and the malondialdehyde content was significantly higher (all P < 0.01) in affected compared with healthy animals. Affected P. przewalskii were treated orally with ZnSO4. The Zn content in the blood increased gradually and serum antioxidant indexes gradually returned to within the healthy range. Zn deprivation in forage thus not only influenced the blood mineral content but also severely disrupted blood parameters and antioxidant function in P. przewalskii.

Abstract
Przewalski's gazelle (Procapra przewalskii) is an endangered ungulate in the Qinghai-Tibet Plateau of China. This study aimed to determine the influence of selenium (Se) deprivation in the natural habitat on the immune index and antioxidant capacity of P. przewalskii. Samples of soil and forage were collected from affected and healthy areas, and animal tissues were collected from affected and healthy P. przewalskii. The samples were used for measuring mineral content and for hematological and biochemical analyses. The results showed that Se concentrations were significantly lower in the soil and mixed forage samples from the affected area than in those from the healthy area. The Se concentrations were significantly lower in blood and hair samples from affected P. przewalskii than in those from healthy P. przewalskii. Meanwhile, hemoglobin, packed cell volume, and platelet count of affected P. przewalskii were significantly lower than those of healthy P. przewalskii. The serum level of glutathione peroxidase and total antioxidant capacity were significantly lower and the serum levels of malondialdehyde, total nitric oxide synthase, and lipid peroxide were significantly higher in affected P. przewalskii. The serum levels of interleukin (IL)-1β, IL-2, tumor necrosis factor-alpha, immunoglobulin A (IgA), and IgG significantly decreased and the serum levels of IL-6 and IgM significantly reduced in affected P. przewalskii compared with healthy P. przewalskii. Therefore, the findings indicated that Se deprivation in soil and forage caused oxidative stress damage and posed a serious threat to the immune function of P. przewalskii.

Abstract
Determination of wool mineral content to assess the animal' mineral status has been extensively used, but the results are controversial. One of the possible contributing factors is that the sampling material in previous studies was collected from a long staple, a fact that could mask the response to recent differences in mineral intake. Therefore, the aim of the present study was to test the sensitiveness of newly grown wool to different dietary mineral intake. Twenty Tsigai ewes were allocated into five dietary treatments with similar hay and concentrate intake but different premix inclusion rates in the concentrate (3, 4, 5, 6, and 7%). Wool was sampled on the left side from a 5 × 5 cm area using bent scissors at the beginning of the trial and from the very same area 28 days later. Samples after cleaning and mineralization were analyzed with ICP-OES (Perkin-Elmer, Optima 3300 DV) for calcium, phosphorus, magnesium, sodium, selenium, zinc, copper, and sulfur content. Long fleeces had significantly lower Ca and Se content compared to the newly grown wool samples of the group at the premix manufacturer's suggested level of supplementation (5%). Macrominerals in fresh wool did not respond to increased dietary supplementation. Se and Zn content of wool had a strong relationship with the daily intake (R2 = 0.95 and R2 = 0.97, respectively.) In conclusion, the mineral content of long fleeces can be different compared to recently developed wool fiber. This indicates that, in some cases, analyzing long staples for mineral status can be misleading. Our results showed that wool could be a sensitive indicator of low selenium and high zinc intake. Mineral interactions can significantly affect the actual availability of trace minerals; therefore, a more careful design of premixes is needed. The described method seems to be applicable in livestock farming, but the mineral interactions that may alter the results need to be further explored.

Abstract
Wumeng semi-fine wool sheep are affected by a disease, characterized by emaciation, stiffness and trembling of the limbs, weakness and inability to stand, and sudden death. The objective of the study was to determine possible relationships between the disease and mineral deficiencies. Samples of wool, blood, and liver were collected from affected and healthy sheep. Samples of soil and forage were collected from affected and unaffected areas. The samples were used for hematological and biochemical analyses and mineral nutrient measurements. Results showed that selenium concentrations in forage and soil samples from affected areas were significantly lower than those from unaffected areas (P < 0.01). Meanwhile, selenium concentrations of wool, blood, and liver from the affected sheep were also significantly lower than those from the healthy sheep (P < 0.01). The mean concentration of hemoglobin (Hb), packed cell volume (PCV), and mean corpuscular hemoglobin (MCH) from the affected sheep were significantly lower than those from the healthy sheep (P < 0.01). Serum glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), and catalase (CAT) activity in the affected sheep were significantly lower than those in the healthy sheep (P < 0.01). Serum creatine phosphokinase (CPK), lactate dehydrogenase (LDH), glutamate pyruvate transaminase (GPT), glutamic oxaloacetic transaminase (GOT), alkaline phosphatase (ALP), and malondialdehyde (MDA) values in the affected sheep were significantly higher than those in the healthy sheep (P < 0.01). Serum concentrations of free triiodothyronine (FT3) and triiodothyronine (TT3) in the affected sheep were significantly lower than those in the healthy sheep; serum concentrations of free tetraiodothyronine (FT4) and tetraiodothyronine (TT4) in the affected sheep were significantly higher than those in the healthy sheep (P < 0.01). But the administration of selenium and vitamin E by hypodermic injection prevented and cured the disease. The injection contains 0.1% and 5% of sodium selenite and vitamin E, respectively. A single dose is 6, 6, and 2 mL for mature ewe, mature ram, and lamb, respectively, repeated only once 15 days later. This study demonstrated that the disorder of Wumeng semi-fine wool sheep was mainly caused by the selenium deficiency in soil and forage.

Abstract
A diagnosis of heavy metal poisoning in sheep living on pastures in the vicinity of a smelting facility in the Wumeng mountain area of China was based on laboratory tests and clinical symptoms. Furthermore, heavy metal contamination in the food chain was found to have a deleterious effect on the health of local residents. The levels of copper(Cu), zinc(Zn), cadmium (Cd), and lead (Pb) in irrigation water, soil, forages, and animal tissues were measured in samples taken from the vicinity of a smelting facility and control samples. Heavy metal contents in food (corn, rice, and wheat), as well as in human tissues (blood and hair) obtained from local residents were also determined. Hematological values were also determined in human and animal samples. The content of Cu, Zn, Cd, and Pb in irrigation water, soils, and forages were markedly higher in affected areas than in samples from healthy pastures. Concentrations of Cd and Pb were 177.82 and 16.61 times greater in forages than controls, respectively, and 68.71 and 15.66 times greater in soils than controls, respectively. The heavy metal content in food (corn, rice, and wheat) from affected areas was markedly higher than in the control samples. Cd and Pb content in the tissues of affected sheep were markedly higher than in control animals (P < 0.01), while concentrations of Cd and Pb in blood and hair samples from local residents were markedly higher than in control samples (P < 0.01). The occurrence of anemia in affected humans and animals followed a hypochromic and microcytic pattern. The intake of Cd and Pb was estimated according to herbage ingestion rates. It was found that the levels of Cd and Pb which accumulated in sheep through the ingestion of vegetation growing in the sites closest to the smelter were approximately 3.36 and 38.47 mg/kg body wt./day, respectively. Such levels surpassed the fatal dosages for sheep of 1.13 mg Cd/kg body wt/day and 4.42 mg Pb/kg body wt./day. The serum total antioxidant capacity in affected humans and animals was significantly lower than in the controls (P < 0.01). Serum protein parameters in affected humans and animals were significantly reduced (P < 0.01); therefore, it was concluded that heavy metal contamination caused harm to sheep, and also posed a significant risk to humans living in the vicinity of the zinc smelting facility.

Comparison of Element Concentrations (Ba, Mn, Pb, Sr, Zn) in the Bones and Teeth of Wild Ruminants from the West Carpathians and the Tian-Shan Mountains as Indicators of Air Pollution. ATMOSPHERE 2019. [DOI: 10.3390/atmos10020064] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/16/2022]
Abstract
Through analyzing the concentrations of selected heavy metals (Ba, Mn, Pb, Sr, Zn) in the bones and teeth of wild living and ecologically equivalent ruminants from the Tian-Shan (Capra sibirica and Ovis ammon polii) and the West Carpathians (Rupicapra rupicapra tatrica) we compared the environmental pollution levels of these two mountain ranges. The samples were analyzed by X-ray fluorescence. Significantly higher contents of Zn and Mn as well as a higher frequency of measurable occurrences of Mn, Ba, and Pb in samples from the West Carpathians confirmed the results of our previous study, that the West Carpathians are relatively more polluted by heavy metals than the Tian-Shan Mountains. The most probably contamination sources are mining and smelting as well as traffic emissions, which can reach remote mountain ranges through long distance atmospheric transport.

[PMID: 30744368 PMCID: PMC6498070 DOI: 10.5713/ajas.18.0622] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Accepted: 12/04/2018] [Indexed: 12/02/2022]
Abstract
Objective Qianbei-Pockmarked goats are affected by a disorder locally referred to as ‘Ruanguzheng Disorder’, which is characterized by emaciation, lameness, muscular relaxation, stiffness of the extremities, and abnormal curvatures of the long bones. Our objective was to determine the relationship between the disorder and phosphorus deficiency. Methods Tissue samples were collected from affected and healthy animals, while soil and herbage samples were collected from affected and healthy pastures. Biochemical parameters were determined using an automatic biochemical analyzer (OLYMPUS AU 640, Olympus Optical Co., Tokyo, Japan). Mineral contents in soil, forage, and tissue were determined using a Perkin-Elmer AAS5000 atomic absorption spectrophotometer (Perkin-Elmer, Norwalk, CT, USA). Results The results showed that phosphorus contents in herbages from affected pastures were markedly lower than those from healthy areas (p<0.01), and the ratio of calcium to phosphorus in the affected herbages was 12.93:1. The phosphorus contents of wool, blood, tooth, and bone from affected animals were also markedly lower than those from healthy animals (p<0.01). Serum phosphorus values in affected animals were much lower than those in healthy animals, while serum alkaline phosphatase values from affected animals were markedly higher than those from healthy animals (p<0.01). Inorganic phosphorus values from affected animals were approximately half of that in the control group. Supplementation of disodium hydrogen phosphate prevented and cured the disorder. Conclusion This study demonstrates that Ruanguzheng disorder in Qianbei-Pockmarked goats is primarily caused by phosphorus deficiencies in herbage due to fenced pastures and natural habitat fragmentation.
