Abstract The study was conducted to evaluate the effects of replacing inorganic trace minerals (ITMs) with respective low-dose complexed glycinate minerals (CGMs) on their bioavailability and retention during peak laying period of broiler breeders. In this experiment, 648 ZhenNing broiler breeders (23 weeks old) were randomly allocated to four treatments with six replicates (27 birds/replicate) and fed for 14 weeks including 2 weeks adaptation period. The treatments were T1—ITM, commercially recommended levels of ITMs (Cu, Zn, Fe, and Mn sulphates); T2—MIX, half of the minerals were supplemented with ITMs and half with CGMs; T3—L-CGMs, minerals were supplemented with CGMs (50% level of T1); and T4—M-CGMs, minerals were supplemented with CGMs (70% level of T1). The results showed that birds fed on ITM had lower bioavailability of Fe, Mn, and Zn (P < 0.05) than those fed on L-CGMs, but the highest (P < 0.01) bioavailability of Cu was found in those fed on MIX. Mineral retention (in serum, muscle, bone, and tissues) was not affected by reducing supplementation levels of trace minerals up to 50% of ITMs, but Zn (in serum, liver, kidney, heart, and albumen) and Fe (in serum and the yolk) retention was negatively affected (P < 0.05). In conclusion, replacing dietary ITMs with low-dose complexed glycinate minerals increases the apparent bioavailability of Fe, Mn, and Zn without compromising the mineral retention rates in most of the tissues tested.

Introduction Trace minerals play a vital role in the metabolic processes [1] by acting as catalysts in many hormonal and enzymatic pathways which affect growth, feathering, structure, and overall production performance of birds [2]. Iron (Fe) is a significant component of myoglobin and haemoglobin for oxygen transport and cellular use [3] and participates in energy supplying, immunization, and the process of antioxidation [4].
