Dietary replacement of inorganic trace minerals with lower levels of organic trace minerals leads to enhanced antioxidant capacity, nutrient digestibility, and reduced fecal mineral excretion in growing-finishing pigs

Abstract

IntroductionMore effective and environment-friendly organic trace minerals have great potential to replace the inorganic elements in the diets of livestock. This study aimed to investigate the effects of dietary replacement of 100% inorganic trace minerals (ITMs) with 30–60% organic trace minerals (OTMs) on the performance, meat quality, antioxidant capacity, nutrient digestibility, and fecal mineral excretion and to assess whether low-dose OTMs could replace whole ITMs in growing-finishing pigs' diets.MethodsA total of 72 growing-finishing pigs (Duroc × Landrace × Yorkshire) with an initial average body weight of 74.25 ± 0.41 kg were selected and divided into four groups with six replicates per group and three pigs per replicate. The pigs were fed either a corn-soybean meal basal diet containing commercial levels of 100% ITMs or a basal diet with 30, 45, or 60% amino acid-chelated trace minerals instead of 100% ITMs, respectively. The trial ended when the pigs' weight reached ~110 kg.ResultsThe results showed that replacing 100% ITMs with 30–60% OTMs had no adverse effect on average daily gain, average daily feed intake, feed/gain, carcass traits, or meat quality (P > 0.05) but significantly increased serum transferrin and calcium contents (P < 0.05). Meanwhile, replacing 100% ITMs with OTMs tended to increase serum T-SOD activity (0.05 ≤ P < 0.1), and 30% OTMs significantly increased muscle Mn-SOD activity (P < 0.05). Moreover, replacing 100% ITMs with OTMs tended to increase the apparent digestibility of energy, dry matter, and crude protein (0.05 ≤ P < 0.1) while significantly reducing the contents of copper, zinc, and manganese in feces (P < 0.05).DiscussionIn conclusion, dietary supplementation with 30–60% OTMs has the potential to replace 100% ITMs for improving antioxidant capacity and nutrient digestibility and for reducing fecal mineral excretion without compromising the performance of growing-finishing pigs.

“…Заміна в раціоні неорганічних мікроелементів меншими рівнями органічних мікроелементів призводить до посилення антиоксидантної здатності, засвоюваності поживних речовин і зменшення виділення мінеральних речовин з фекаліями (Xiong et al, 2023).…”

“…In the conducted studies on examining the effect of additional administration of a copper chelate complex, hybrid young animals of Velyka Bila×Landras were used. Copper is used in pig feeding as an additive to stimulate animal productivity.Various sources of copper can alter the composition of the gut microbiota and improve gut health (Xiong et al, 2023). The use of unconventional natural mineral additives in diets for fattening young pigs led to more efficient use of minerals in diets, which contributed to more intensive growth of animals and reduced feed costs per unit of production (Bomko & Baranyuk, 2017;Verbelchuk et al, 2021).…”

Поряд із забезпеченням енергією, протеїном та біологічно активними речовинами особливу роль відіграють мінеральні речовини, незважаючи на те, що вони необхідні тільки в невеликих кількостях, їхні функції в організмі не можуть бути компенсовані іншими компонентами (Voloshchuk et al, 2014;Ibatullin et al, 2014;Kozenko et al, 2022;Xiong et al, 2023).…”
