“…This study found that palygorskite inclusion can reduce yellowness and redness of meat, and this effect became more pronounced with the increasing dosage of palygorskite (from 10 to 20 g/kg). The results obtained in the current study were consistent with findings of Chalvatzi et al [11] in which laying hens given diets supplemented with 1.0 % palygorskite for 24 weeks produced eggs with significantly lighter eggshell and yolk color. Most of the variation in meat color of normal meat quality can be explained by the pigment content, myoglobin forms, and internal reflectance [6], which in turn suggested that the reduced meat color (yellowness and redness) observed in this study may be due to the affinity between palygorskite and pigments [13,41].…”

“…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.…”

“…The color of egg yolks mainly originates from yellow (e.g., lutein, zeaxanthin, apo-ester) and red (e.g., canthaxanthin, citraxanthin, astaxanthin) carotenoids or xanthophylls in the diets [8]. However, clay supplementation including palygorskite to the laying hen diet can induce the reduced yolk color [9][10][11], and it is most likely due to their affinity for pigments [12,13], suggesting that clay supplementation would decrease the accumulation of pigments in yolk. Most of the variation (86-90 %) in lightness, redness, and yellowness, chroma (saturation) and hue angle of pork of normal meat quality could be explained by the pigment content, myoglobin forms, and internal reflectance [6].…”

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.

“…Control group (CON) was fed diets in mash form, according on the bird age (Table 1) which contained no anticoccidal or antimicrobial growth promoters; the diet of the second group (ATT) was further supplemented with at- Tzora et al: Oregano, Attapulgite, Benzoic (Chalvatzi et al, 2014). The main constituents of the examined oregano essential oil are presented in Table 2 (the chemical composition was provided by the supplier).…”

The aim of the present study was to investigate the effects of oregano, attapulgite, benzoic acid and their combination on broiler performance, microflora composition of jejunum and cecum, intestinal architecture and breast and thigh meat composition. A total of 400 one-day-old broiler chicks were used in a 42-day trial. They were randomly distributed into five treatments with four replicates of twenty chickens per pen: Control group; Attapulgite group; Oregano essential oil group; Benzoic acid group; Mixed group. At the end of the trial, total counts of bacteria, Enterobacteriaceae, Lactobacilli, and Clostridium perfringens were enumerated by real time PCR at both jejunum and cecum. Intestinal morphology was carried out in duodenum, jejunum and ileum, for villus height and crypt depth. Cell proliferation was also evaluated in the small intestine and the cecum. The results showed that oregano and benzoic acid improved some growth performance parameters. The combined use of the examined substances increased enterobacteria counts in the jejunum, and cell proliferation in the duodenum and the jejunum. Benzoic acid improved intestinal wall morphology in the ileum. In conclusion, the combined dietary supplementation with oregano, attapulgite and benzoic acid can be a novel tool to beneficially modulate broiler chickens performance.

The present study investigated the effects of attapulgite supplementation in sow diets during gestation and lactation on sow performance. The study comprised two reproductive phases (cycles) in two commercial farrow to finish farms: Farm A (capacity: 550 sows) and Farm B (capacity: 220 sows). The treatment groups were: a) control group (CN): the sows were fed a common gestation or lactation diet; b) attapulgite group (AT): the sows were fed the CN diet supplemented with attapulgite at 0,7% level; c) attapulgite plus group (AT+): the sows were fed the CN diet supplemented with attapulgite (0.7%) and a mix of enzymes, live yeast and amino acids (0.1%), at a total of 0.8% level. Within each cycle the sows included per treatment were: 24 for Farm A; 12 for Farm B. Initially data were analyzed per cycle and per each farm. Data from sows that completed both cycles within each farm, were analyzed by repeated measures analysis. Regarding sow parameters, sow body weight loss during lactation tended to be greater in AT sows compared to CN sows during cycle 1 in Farm B and was greater in AT and AT+ than CN sows in Farm A that completed both cycles (P=0.063 and P=0.023, respectively). A greater litter size 24h postpartum was observed in favour of AT compared to CN group during cycle 1 in Farm A and in sows that completed both cycles in Farm A (P=0.001 and P= 0.011, respectively). Litter size at weaning was greater in sows from the AT group than CN during cycle 1 and 2 in Farm A, in cycle 1 in Farm B and in sows that completed both cycles in Farm A (P=0.004, P=0.037, P=0.037, and P=0.022, respectively). Piglet weight at weaning and average daily gain during lactation were greater in AT group than CN and AT+ in sows that completed both cycles in Farm A (P=0.049 and P=0.040 respectively). Notable similar effects, although not statistically significant, were also observed in Farm B. This field study suggests that attapulgite supplementation in sow diets can improve performance indexes. Further research should investigate the underlying mechanisms involved.
