“…This may be firstly associated with the nutrition dilution aroused by palygorskite supplementation. Also, palygorskite that possesses the binding potential for nutrients including pigments and trace mineral elements was postulated to account for this phenomenon [11,23]. The results regarding growth performance in this study were partially in agreement with the results of Pappas et al [4] who reported that dietary 1.0 % (10 g/kg) palygorskite supplementation used as a pellet binder did not alter the growth performance of broilers during a 6-week study.…”

“…In the present study, palygorskite supplementation that exceeded 5 g/kg also significantly decreased muscular Cu and Pb accumulation, indicating that palygorskite could be also used to decrease Cu and Pb retention in vivo and this effect was associated with its dosage. However, Zhang et al [23] have recently found that the inclusion of 2 % palygorskite decreased the retention of Cd rather than Pb or Cu in the muscle of blunt snout bream (M. amblycephala). This discrepancy is likely to result from animal species and different contents of mineral elements in the diet.…”

“…In vitro studies have demonstrated palygorskite used as an adsorbent exhibited a prominent capacity for the removal of Pb or Cd in aqueous solution, and heavy metal contained water or soil [20][21][22]. Recently, Zhang et al [23] have shown that dietary 2 % palygorskite supplementation significantly decreased Cd accumulation in the muscle of blunt snout bream (Megalobrama amblycephala).…”

The present study was conducted to investigate different levels of palygorskite supplementation on the growth performance, meat quality, muscular oxidative status, and mineral element accumulation of broilers. One hundred ninety-two 1-day-old Arbor Acres broiler chicks were allocated to four dietary treatments with six replicates of eight chicks per replicate. Birds in the four treatments were given a basal diet supplemented with 0, 5, 10 and 20 g/kg palygorskite for 42 days, respectively. Compared with the control group, neither 5 g/kg nor 10 g/kg palygorskite inclusion affected growth performance of broilers during the 42-day study (P > 0.05). However, the highest level of palygorskite supplementation at 20 g/kg increased feed/gain ratio (F/G) of broilers (P < 0.001). Yellowness (P < 0.001) and redness (P = 0.003) of breast muscle and yellowness of leg muscle (P = 0.001) were decreased by palygorskite supplementation at the levels of 10 g/kg and especially 20 g/kg. In addition, redness of leg muscle was also reduced by the inclusion of 20 g/kg palygorskite (P = 0.009). In contrast, malonaldehyde (MDA) accumulation in the breast muscle was significantly increased by 20 g/kg palygorskite supplementation (P < 0.001). Supplementation of palygorskite at either 10 or 20 g/kg significantly decreased lead (Pb) accumulation in the breast (P = 0.001) or thigh (P = 0.045) and copper (Cu) accumulation in the breast (P = 0.022). In conclusion, growth performance, meat color, and antioxidant capacity of meat would reduce with the increasing level of palygorskite supplementation, whereas a higher level of palygorskite (10 or 20 g/kg) can alter mineral element accumulations in muscles as evidenced by reduced muscular Cu and Pb contents.

“…Similar results were also observed by Cheng et al (2016) who reported that dietary Pal inclusion, at either 10 or 20 g/kg, significantly decreased Pb accumulation in the breast or thigh muscle. Additionally, Zhang et al (2015) reported that 2% Pal supplementation reduced muscular Cd accumulation in blunt snout bream. Inclusion of diets with excess minerals could lead to antagonism.…”

“…Due to their potential neurotoxic, teratogenic and lethal effect, the accumulations of heavy metals including lead (Pb), chromium (Cr) and cadmium (Cd) would pose a threat to all forms of life including human, animal, plant and aquatic life through the food chain (Carpenter, 1987;Goyer, 1996;Ruff et al, 1996;Zhuang et al, 2009). Previous studies have shown that Pal, as an effective solution, could be used for the removal of heavy metals both in vitro (Alvarez-Ayuso and GarciaSanchez, 2003;Potgieter et al, 2006;Fan et al, 2009) and in vivo (Zhang et al, 2015;Cheng et al, 2016).…”

The present study was conducted to investigate the effects of zinc (Zn) bearing palygorskite (ZnPal) inclusion on the carcass traits, chemical composition of muscle, and muscular lead (Pb) and chromium (Cr) contents of broilers. A total of 240 1-day-old Arbor Acres broiler chicks were randomly divided into 5 dietary treatments with 6 replicates of 8 chicks each. Broilers in the 5 treatments were fed a basal diet supplemented with 0 (Control group), 20, 40, 60, and 80 mg/kg Zn in the form of ZnPal for 42 days, respectively. There were no differences in the carcass yield, abdominal fat yield, subcutaneous fat thickness, and intramuscular fat width among treatments (P＞0.05). Compared with the control group, the eviscerated yield (P＝0.010) and thigh muscle yield (P＝0.046) were quadratically increased by the supplementation of ZnPal (P＜0.05). Similarly, the breast muscle yield was linearly (P＝0.024) and quadratically (P ＝0.011) increased by ZnPal inclusion. The addition of ZnPal to diets of broilers also linearly (P＝0.002) increased fat content in the thigh. Moreover, the supplementation of ZnPal linearly and quadratically reduced the content of muscular Pb and the content of Cr in the thigh muscle (P＜0.05). It was concluded that ZnPal inclusion could improve carcass traits, increase fat content in the thigh, and reduce the accumulations of Pb and Cr in the muscles, and this effect was more pronounced when extra Zn dosage in the form of ZnPal was 40 mg/kg.

The objective of this study was to evaluate influence of dietary palygorskite (Pal) supplementation on growth performance, mineral accumulations in the tissues (livers, kidneys, and muscles), antioxidant capacities, and meat quality of broilers fed lead (Pb)-contaminated diet. One-hundred forty-four male broiler chicks were randomly divided into three treatment groups, receiving a corn-soybean meal basal diet (the control group), the basal diet contaminated with 10 mg/kg Pb (the Pb group), and the basal diet with 10-g/kg Pal supplementation and 10-mg/kg Pb contamination (the Pal/Pb group) from 1 to 42 days of age, respectively. Treatments did not affect growth performance of broilers in the 42-day study (P > 0.05). Compared with the control group, Pb contamination increased Pb accumulation in the livers, kidneys, and muscles (P < 0.05); elevated malondialdehyde accumulation in the livers, kidneys, and breast muscles; glutathione peroxidase activity in the livers and superoxide dismutase activity in the kidneys (P < 0.05); exacerbated drip loss in the pectoralis muscles (P < 0.05); and reduced glutathione peroxidase activity in the pectoralis muscles (P < 0.05) of broilers at 42 days of age. The values of these parameters were reversed in the Pal/Pb group to levels comparable with those in the control group (P < 0.05). Additionally, Pal supplementation reduced redness value in the pectoralis muscles (P < 0.05), and decreased Cu concentration in the pectoralis muscles and livers at 42 days of age as well as its accumulation in the kidneys at both 21 and 42 days of age compared with the other two groups (P < 0.05). The results suggested that dietary Pal supplementation would decrease Pb residue in the tissues, alleviate oxidative stress, and affect meat quality of broilers exposed to Pb.
