“…SOD is an essential component of the antioxidant system, it can antagonize and block the damage of free radicals to cells by scavenging free radicals in animals, and repair the damage in time [31,32]. SOD can be classified into 4 groups based on the metal residue that binds to the active site: Mn-SOD, Cu/Zn-SOD, ironsuperoxide dismutase (Fe-SOD) and nickel-superoxide dismutase (Ni-SOD) [33,34]. Mn-SOD helps to protect the cells from the adverse effects of excess ROS in aerobic organisms.…”

The purpose of this research is to better understand the effect of different copper (Cu) levels of feed on the antioxidant capacity in the native sheep, solve the adverse effects of local seasonal Cu deficiency on sheep, and provide a reasonable reference for Cu supplementation. 10 healthy native sheep were selected as the control group (C group). 40 Cu-deficient native sheep were selected as tested group, and divided randomly into 4 groups (n = 10), supplied by CuSO 4 (0, 20, 40, 60 mg/kg for group I, group II, group III and group IV, respectively). The results showed that the level of Cu, hemoglobin (Hb), packed-cell volume (PCV), albumin (ALB), the activities of ceruloplasmin (CP), Cu/Znsuperoxide dismutase (Cu/Zn-SOD) and catalase (CAT) in group I were significantly lower than those in C group, group II, III, IV (P<0.05), but malondialdehyde (MDA) concentration was higher. The activities of these antioxidant enzymes and MDA concentration had no significant difference between C group, group II, III, IV (P>0.05), but group III had the highest antioxidant enzymes activity and the lowest MDA concentration. There was no significant difference in manganese (Mn), zinc (Zn), iron (Fe), molybdenum (Mo), selenium (Se), red blood cell count (RBC), white blood cell count (WBC), blood urea nitrogen (BUN), alanine transaminase (ALT), alkaline phosphatase (ALP), aspartate aminotransferase (GOT), total cholesterol (TC), manganese-superoxide dismutase (Mn-SOD) between all groups (P>0.05). Conclusion: The function of antioxidant system of the native sheep in Weining County have seriously reduced. Added CuSO 4 to the diet increase the activity of antioxidant enzymes and improve the health parameters, but them did not increase linearly. Added 40 mg/kg CuSO 4 , the activity of antioxidant enzymes was the highest and the content of MDA was the lowest. Therefore, it is recommended to add 40 mg/kg CuSO 4 to diet of the native sheep in Weining County.

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.

“…The Wumeng Prairie is a key pastureland for Wumeng semi-fine wool sheep. These native sheep were also vital to the production system in the Wumeng Prairie, and mainly distributed in the high altitude pasture in Weining County of the Wumeng Prairie, Southwest China [4,5]. Wumeng semi-fine wool sheep have high growth performance, mild temperament and strong adaptability to alpine pastoral ranges [6,7].…”

To assess the impact of sulfur(S) fertilization on antioxidant capacity of grazing Wumeng semifine wool sheep in copper(Cu) polluted meadow, and explore the control methods of Cu pollution in natural pasture, fertilizer treatment and grazing experiments were carried out in Weining County of the Wumeng Prairie, Guizhou Province, Southwest China. 24 ha Cu-polluted meadows were fenced, and randomly divided into four groups (3 replications/group, 2 ha/replication): 1) control group, no fertilizer; 2) the tested groups, applied ammonium sulfate [(NH4) 2 SO 4 ] (300, 400, and 500 kg/ha for group I, group II, and group III, respectively). A total of 72 healthy Wumeng semi-fine wool sheep (aged one year, 32.8±1.3 kg) were used in this study. All animals were randomly divided into 4 groups (3 replications/group, 6 sheep/replication) and assigned to the tested pastures. The grazing experiment lasted for 60 days. The results showed that the contents of N, Mn, Zn, and S in herbage in fertilized pastures were markedly higher than those in control group (P<0.01). The contents of Cu, Fe, and Se in herbage in fertilized pastures were significantly lower than those in control group (P<0.01). There were no extreme differences among the fertilized pastures (P>0.05). The contents of Mn, Zn, and S in serum and liver in the tested sheep were significantly higher than those in control animals (P<0.01). The contents of Cu, Fe, and Se in serum and liver in the tested sheep were extremely lower than those in control animals (P<0.01). The levels of Hb, RBC, and PCV in blood in the tested sheep, and the activities of serum SOD, GSH-Px, T-AOC, CAT, and Cp in the tested sheep were extremely higher than those in control sheep (P<0.01). The contents of serum MDA in the tested sheep were significantly lower than those in control animals (P<0.01). There were no great differences among the tested groups in physiological and biochemical parameters (P>0.05). The current results indicated that fertilization of
