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.

Importance of feed efficiency for sustainable intensification of chicken meat production: implications and role for amino acids, feed enzymes and organic trace minerals

“…Indeed, De Marco et al (2017) demonstrated that similar growth performance and lower mineral excretion can be achieved by using organic TM at 50% of the recommended dosage for inorganic ones, whereas the complete substitution (100%) of inorganic minerals with organic sources led to comparable or higher excretion. Similarly, Carvalho et al (2018) observed a quadratic response on mineral excretion in relation to the dosage of organic minerals, with lowest values detected in birds fed diets with 50% and 75% of organic TM compared to those receiving diets with 100% organic or inorganic minerals. Together, these results indicate that there is a need for a better understanding of mineral nutrition in broiler chickens, with particular regard to the accurate determination of the TM requirements of modern broiler hybrids and the bioavailability of organic sources.…”

“…improved FE and body weight gain, and lower mortality) associated with the dietary use of organic TM have also been observed in broilers challenged with coccidiosis plus Clostridium perfringens (Bortoluzzi et al 2019). Finally, the lack of significant improvements in performance traits or FE (as observed in some studies reported in Table 1) should not necessarily be viewed negatively as, in some cases, it has been demonstrated that similar growth performance and efficiency can be achieved by supplementing organic minerals at lower concentrations compared to inorganic sources (Echeverry et al 2016;Kwiecień et al 2016;De Marco et al 2017;Carvalho et al 2018;Olukosi, van Kuijk, and Han 2019), with potential economic and environmental benefits.…”

“…Furthermore, some papers provided evidence that feeding broilers diets enriched with organic TM can diminish mineral excretion (De Marco et al 2017;Carvalho et al 2018;M'Sadeq et al 2018), which is fundamental for limiting the environmental impact of broiler production as previously discussed. On the other hand, Vieira et al (2020) reported no significant effect of the TM source on mineral excretion (with the only exception of Mn at 48 d of broilers age), although they found that lower concentrations of TM in feed reduced Zn, Cu and Mn concentrations in the litter.…”

“…Total replacement of inorganic TM with organic ones led to similar or higher excretion levels. Carvalho et al (2018) Cu, Fe, Mn, Zn Proteinates No significant changes in production traits. Excretion levels of trace minerals varied quadratically in relation to the dietary inclusion levels of organic minerals (diets with 50% and 75% of organic minerals reduced the excretion levels of all trace elements).…”

“…On the other hand, Vieira et al (2020) reported no significant effect of the TM source on mineral excretion (with the only exception of Mn at 48 d of broilers age), although they found that lower concentrations of TM in feed reduced Zn, Cu and Mn concentrations in the litter. Finally, an interesting aspect emerged in some studies (De Marco et al 2017;Carvalho et al 2018): mineral excretion was not significantly affected by the mineral source when organic TM were used at 100% of the recommended concentration for inorganic minerals. Indeed, De Marco et al (2017) demonstrated that similar growth performance and lower mineral excretion can be achieved by using organic TM at 50% of the recommended dosage for inorganic ones, whereas the complete substitution (100%) of inorganic minerals with organic sources led to comparable or higher excretion.…”
