“…The severity of FPD was lower in birds fed a high Zn diet and reared on dry litter, but not on wet litter. These results are supported by the findings of Hess et al. (2001) who noted that FPD lesions were reduced significantly in female broilers fed diets containing Zn‐amino acid complexes.…”

“…Biotin had no effect in turkeys with a litter moisture content of approximately 45% (Mayne et al., 2007b). Moreover, organic Zn did not reduce FPD lesions in male broilers under cold climatic conditions (Hess et al., 2001) which in turn may affect the litter quality. In this study, biotin or Zn significantly reduced the development of foot pad lesions when the litter moisture was approximately 25%.…”

Foot pad dermatitis (FPD) is very common in turkeys and it is an animal health and welfare issue affecting not only performance and walking ability but also the carcass quality. Thus, there is a great need to find out the preventive measures against this problem. The potential roles of extra dietary biotin, Zn and mannan-oligosaccharides (MOS) in preventing the development of FPD were assessed in this study which was conducted on 2-week-old female turkeys over a period of 4 weeks. The birds were allotted to four groups, with 29 each, and housed on dry wood shavings in floor pens. The turkeys were fed a control (300 μg biotin and 50 mg Zn/kg), high biotin (2000 μg/kg), high Zn (150 mg/kg) or MOS (1%) diet. Half of the turkeys in each group were additionally exposed to wet litter (27% DM) for 8 h daily in adjacent separate boxes. Foot pads of the birds were examined on days 0, 7, 14, 21 and 28 and assessed macroscopically and histopathologically for foot pad lesions. High dietary levels of biotin or Zn significantly reduced the severity of FPD on dry litter (score 1 vs. 2 in control) but not on wet litter. However, MOS did not affect the severity of foot pad lesions either on dry or wet litter. In addition, the severity was overall substantially higher on wet (approximately three times) than on dry litter. The present results suggest that adding high levels of biotin or Zn to the diet could reduce the development and severity of FPD on dry litter but without having any preventive effects on wet litter. Finally, the high litter moisture appears to be the major factor resulting in FPD. Therefore, the litter should be maintained dry to minimize the prevalence and severity of FPD in turkeys.

“…Generally, it is accepted that bioavailability of trace mineral supplements from organic sources is higher than that of the inorganic sources owing to the ability of organic compounds, such as amino acids, to bind strongly to divalent minerals under physiological pH conditions (Cheng et al, 2005;Yan and Waldroup, 2006;Ao et al, 2009). Conflicting data have been reported regarding the relative efficacy of different organic compared with inorganic Zn sources in enhancing broiler performance (Hess et al, 2001;Swiatkiewicz et al, 2001). Zn requirements have been estimated to be 37 mg/kg from organic sources (Ao et al, 2007) and 84 mg/kg from inorganic sources (Huang et al, 2007).…”

A total of 400 one-day-old, straight-run, commercial (Ross 308) broiler chicks were used to evaluate the effects of two dietary levels of zinc (Zn) sources on broiler chick performance, carcass traits and blood parameters. Corn-soybean diets were formulated for three rearing phases (starter, grower and finisher). The two dietary treatments applied consisted of the addition per kg of diet of 80mg of inorganic Zn (ZnO) (T1), or 80mg of ZnO plus 42mg of an organic Zn-amino acid complex (Availa-Zn120; Zinpro Corporation, Eden Prairie, MN, USA), totaling 122mg of the combined organic and inorganic Zn sources (T2). Birds were distributed according to a completely randomized design in the two treatments with eight replicates (pens) of 25 birds each. Feed and water were provided ad libitum. On day 42, blood samples were taken from four birds closest to the group average weight per replicate (32 per treatment) and then slaughtered for carcass evaluation. The results of this study did not find any significant effect of either of the evaluated Zn sources on broiler growth performance. Mortality rate was significantly lower (p<0.05) by the higher Zn concentration and the Zn sources group (T2). Carcass yields were not significantly influenced by the treatments. Breast quality showed significant improvement (p<0.05) in shear force (T2), indicating juicier meat. Higher concentrations (p<0.05) of Zn, Phosphorus (P), and total protein in blood were noted in (T2). Birds fed a mixture of organic and inorganic Zn source (T2) presented overall better results.

“…Zinc sources are the most studied mineral among these compounds. Some researchers have reported improved growth rate and/or feed conversion with organic zinc sources in broiler (Cao et al, 2000;Hess et al, 2001;Leeson, 2005;Ao et al, 2006;Novak and Troche, 2007;Bao et al, 2007;Rossi et al, 2007).…”

This study was conducted to investigate the effects of prebiotic and organic zinc alone and in combination in broiler diets on the live weight gain (LWG), feed consumption (FC), feed consumption ratio (FCR), carcass yield, some relative organ weights and blood parameters. A total of 160 Ross 308 one-day old male chicks were assigned to 4 treatment groups with 4 replicates of 10 birds each. Treatment for each group consisted of: first group (control group) received basal diet without supplementation; second group received 1 g/kg Mannanoligosaccharide (MOS); third group received 80 mg/kg organic zinc (OZn); and fourth group received 80 mg/kg organic zinc + 1 g/kg Mannanoligosaccharide (MOS+OZn). The study lasted 42 days. The supplementation of MOS and OZn had no effect on the LWG, FC, FCR, carcass yield, serum aspartate aminotranferase, (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and triglyceride levels during the experiment (P>0.05). Relative organ weights (liver, spleen, pancreas) were significantly higher in OZn group than those in the other groups (P<0.001). There was a significant difference in serum total cholesterol and glucose levels between treatment groups and control group (P<0.001). Serum Zn and Fe levels were significantly lower in control group than those in OZn and MOS+OZn groups (P<0.001). The highest and the lowest Cu levels were in the MOS+OZn and control groups, respectively (P<0.001). These data suggest that OZn with MOS combination may have a beneficial effect on serum mineral level in broilers.
