Effects of organic mineral dietary supplementation on production performance and egg quality of white layers

Abstract: This trial aimed at evaluating the effect of organic trace mineral supplementation of commercial layer diets on productive performance and egg quality. One-hundred-ninety-two Hy Line W36 white 69-w-old layers were distributed into a completely randomized design with three treatments, and eight replicates, with eight birds each. Treatments consisted of a basal diet supplemented with inorganic trace minerals (R1), and two others experimental diets containing 0.250 ppm (R2) and 0.500 ppm (R3) of an organic source… Show more

“…Layers fed the T2 diet produced (p<0.05) thicker eggshells than that compared with CON in week 4. However, Fernandes et al (2008) did not find any positive effect of organic trace minerals on eggshell thickness, specific gravity, or cracked egg percentage. The improvement in eggshell thickness observed in the present experiment may be due to the interaction of trace minerals with calcium crystals during eggshell formation or to the catalytic properties of minerals that stimulate some key enzymes involved in the process of membrane or eggshell synthesis.…”

“…Conversely, Sechinato et al (2006) reported that there was no effect of organic minerals on the performance and egg production compared with inorganic minerals in 48-to 60-week-old layers. Likewise, Fernandes et al (2008) noted that supplementation of organic trace minerals did not affect egg production or quality. The response to mineral supplementation depends on mineral concentration in the basal diet (Payane et al 2005).…”

“…Skrivan et al (2006) detected a signifi cantly lower difference in the group supplemented with selenized yeast compared with the control group. Fernandes et al (2008) reported a signifi cantly higher ratio of fresh and dried yolk yields with dietary inclusion of an organic mineral blend at 0.250 and 0.500 kg/ton.…”

“…According to Fernandes et al (2008), organic minerals can improve production and reduce mortality and stress, as well as reduce excretion into the environment since they are absorbed and retained in the poultry's body. However, the results of its use are conflicting.…”
