EXCRETION LEVEL OF TRACE MINERALS IN BROILERS FED ORGANIC MINERAL

Abstract The aim of this current study was to determine the excretion level of the trace organic minerals copper, iron, manganese, and zinc added to broiler diets at different inclusion levels. The treatments consisted of a corn and soybean meal based diet supplemented with inorganic minerals or levels of organic minerals: basal diet containing 0% of microminerals of organic source (MO), 50% MO, 75% MO, and 100% MO. Excretion levels of organic trace minerals varied quadratically in relation to the inclusion levels of organic minerals. The inclusion levels of 50% and 75% of organic minerals led to animals with lower excretion levels of all trace elements evaluated. The performance variables did not suffer any influence of treatments, even when the amount of organic minerals was equivalent to 50% of the recommended levels. The diet with the addition of trace organic minerals at the level of 50% is more efficient since it provides lower levels of trace minerals excretion keeping poultry performance.

Abstract This study was conducted to investigate effects of inorganic trace mineral (ITMs) replacement with low level organic trace minerals (glycine complex minerals, GCMs; proteolytic complex minerals, PCMs) on growth, tissue mineral retention and mineral excretion in piglets. A total of 128 weaned piglets (Duroc × Landrace × Largewhite, 14.37 ± 0.32kg BW) aged 40d were randomly divided into 4 dietary treatments and fed for 28 days, with 4 replicates of 8 piglets per treatment. Dietary treatments were:(T1) basal + ITMs (Cu, Zn, Fe and Mn, sulfate) at 100% commercial level;(T2) basal + ITMs at 50% commercial level + GCMs at 50% commercial level;(T3) basal + GCMs at 50% commercial level;(T4) basal + PCMs at 50% commercial level respectively. On day 29, six piglets from each group were slaughtered to collect serum, muscle and organ samples. The results showed that ADG of T1, T2 and T3 was higher than that of T4 (P < 0.05), FCR of T1, T2 and T3 was lower than that of T4 (P < 0.01). The retention of trace minerals in tissues and serum is significantly correlated with the supplemental level and source of trace minerals. When 50% commercial level ITMs replaced with GCMs, Cu in serum, heart, liver and pancreas, Fe in liver and muscle was increased (P < 0.05), and liver Zn, Mn in heart, liver and muscle was increased (P < 0.01) respectively. Muscle Zn in T3 was higher than that from T4 (P < 0.05) with same level of organic minerals. Zn, Fe, Mn excreted from urine in pigs fed T2 diet was less than that from T1 (P < 0.05), and urine Zn in T3 treatment is lower than that from T4 (P < 0.05). This study indicated that dietary ITMs replacement with GCMs resulted in higher tissue minerals deposition, and organic trace minerals from GCMs exhibited higher bioavailability than those from PCMs.

This review critically examines the literature on the current status of trace mineral nutrition and the effect of organically complexed trace minerals, focusing on copper (Cu), iron (Fe), manganese (Mn) and zinc (Zn), on broiler chicken production. The requirements of Cu, Fe, Mn and Zn by broiler chickens need to be redefined due to today’s fast growing birds and the availability of organic trace minerals. Zn is one of the key trace minerals for chickens and although it maintains a relatively stable tissue concentration, dietary deficiency of Zn strongly depresses the feed intake, and hence the growth, of broiler chickens. Based on studies using a semiconventional diet, it is reasonable to conclude that the total Zn requirement for broiler chickens is around 60 mg/kg up until day 14 and 70 mg/kg from 14 day onwards, including the Zn content in the basal diet. However, it is difficult to determine the requirements of other organic trace minerals such as Cu, Fe and Mn because under a Zn adequate condition, it is impossible to produce deficient symptoms of these minerals on the basis of growth response. It also identifies gaps in knowledge of inorganic and organic trace mineral nutrition for the modern broiler chicken.

SummaryThe aim of this study was to compare the performance and carcass quality of broilers fed diets containing either a commercial inorganic mineral premix (control) or organic trace minerals (OTM) (Sel-Plex® (Se) and Bioplex® copper (Cu), zinc (Zn), manganese (Mn) and iron (Fe)) in a commercial environment. Four identical houses with a total of 119,500 mixed-sex broiler chickens were used (two treatments × two replicates). Birds were fed identical corn/soybean based rations differing only in mineral form and levels. The inorganic treatment (control) provided Cu, Zn, Fe, Mn and Se at levels of 8, 44, 55, 66 and 0.2 ppm, respectively. The OTM contained 5.5, 22, 5.5, 22 and 0.3 ppm of Cu, Zn, Fe, Mn and Se respectively. Growth and feed conversion during the 35-day trial were not influenced (P > 0.05) by treatments. Over the entire trial period and during the first week of production, birds showed significantly lower (P < 0.05) mortality with the OTM treatment. Between 14 and 31 days, sudden death syndrome was lower (P < 0.05) with the OTM diet. OTM improved feathering at 21 days of age (P < 0.001) and lowered carcass skin tearing (P < 0.05). There was no effect of OTM on carcass yield, breast meat pH, drip loss or on meat colour (L* and b* values). However, birds fed organic minerals had redder breast meat (a*) (P < 0.05) on days three and five after slaughter. The results showed that, under commercial conditions, using lower levels of OTM (except Se) in feed relative to inorganic controls can maintain broiler performance.

Abstract The objective of this study was to investigate the effect of reduced levels of Cu, Zn, Mn in combination from organic mineral source on eggshell quality and mineral retention in hens. After feeding the basal diet (8.82 mg/kg Cu, 24.94 mg/kg Zn, and 16.38 mg/kg Mn) without Cu, Zn, and Mn addition for 4 weeks, hens (39-week-old) were assigned to 5 treatments according to the equal body weight and egg production for 12-week experimental trial. The 5 treatments included the basal diet without Cu, Zn, and Mn (NCON), and NCON added with 16-80-60 mg/kg Cu-Zn-Mn from sulfates (ITM100%), or 4-20-15, 8-40-30 or 16-80-60 mg/kg Cu-Zn-Mn from 2-hydroxy-4-(methylthio)butanoic acid (HMTBA) mineral chelates (OTM25%, OTM50% or OTM100%). Supplementation of Cu, Zn, and Mn had no significant influences on the performance of hens. After 12 weeks feeding, eggshell breaking strength (EBS) decreased in the following order: OTM25% and ITM100% > OTM50% > NCON and OTM100%. The eggshell weight and thickness in OTM25% were greater than that in NCON, while not differing from that in ITM100%. The EBS and eggshell weight linearly decreased with increasing level of OTM. After 12 weeks feeding, supplementation of Cu, Zn, and Mn increased the concentrations of liver Zn, tibia Zn and Mn, and Zn and Mn retention in eggs as compared with NCON. No significant difference was observed in the concentrations of Cu, Zn, and Mn in liver and plasma, and Zn and Mn in eggs between any OTM treatment and ITM100% groups. Addition of OTM at increasing level had quadratic effect on tibia Cu, Zn, Mn concentrations, with the greater retention of Cu, Zn, and Mn in OTM50%. In conclusion, the OTM25% from HMT BA mineral chelates can substitute for ITM100% evaluated by the eggshell quality in the diet of laying hens.

Objective: The objective of this study was to investigate the effects of low doses of organic trace minerals (iron, copper, manganese, and zinc) on productive performance, egg quality, yolk and tissue mineral retention, and fecal mineral excretion of laying hens during the late laying period.Methods: A total of 405 healthy hens (HY-Line White, 50-week-old) were randomly divided into 3 treatments, with 9 replicates per treatment and 15 birds per replicate. The dietary treatments included feeding a basal diet + inorganic trace minerals at commercial levels (CON), a basal diet + inorganic trace minerals at 1/3 commercial levels (ITM), and a basal diet + proteinated trace minerals at 1/3 commercial levels (TRT). The trial lasted for 56 days.Results: Compared to CON, ITM decreased (p<0.05) egg production, daily egg mass, albumen height, eggshell strength, yolk Fe concentration, serum alkaline phosphatase activity and total protein, and increased (p<0.05) egg loss and feed to egg ratio. Whereas with productive performance, egg quality, yolk mineral retention, and serum indices there were no differences (p>0.05) between CON and TRT. The concentrations of Fe and Mn in the tissue and tibia were changed notably in ITM relative to CON and TRT. Both ITM and TRT reduced (p<0.05) fecal mineral excretion compared to CON.Conclusion: These results indicate that dietary supplementation of low-dose organic trace minerals reduced fecal mineral excretion without negatively impacting hen performance and egg quality.
