The present study investigated the effect of a moderate substitution of inorganic mineral sources with chelated mineral sources from four weeks prior to parturition throughout lactation on sow and litter performance. In addition, the aims were to determine whether the mineral source and litter performance affect mineral status and accretion in piglets at birth and at weaning. Forty gestating sows in a commercial pig herd were selected and randomly assigned to two experimental groups, with part of the Cu, Mn, Zn and Fe content of the feed added as either an inorganic mineral source or a chelated mineral source. From each sow, one piglet was randomly selected at birth and at weaning for total body mineral analysis. Neither the performance of the sows and the piglets nor the total body mineral concentrations of the piglets at birth and at weaning were significantly different between the two diet groups (<i>P</i> > 0.05). Fe, Na and P content of piglets at birth were inversely correlated with birth weight (<i>r</i> = –0.447, <i>P</i> = 0.004 for Fe; <i>r</i> = –0.431, <i>P</i> = 0.005 for Na; <i>r</i> = –0.340, <i>P</i> = 0.032 for P). Daily accretion rate of K and Ca of piglets was positively correlated with piglet growth performance during the entire lactation period (<i>r</i> = 0.469, <i>P</i> = 0.008 for K; <i>r</i> = 0.581, <i>P</i> < 0.001 for Ca), and negatively correlated with number of liveborn piglets (<i>r</i> = –0.424, <i>P</i> = 0.014 for K, and <i>r</i> = –0.405, <i>P</i> = 0.027 for Ca). In conclusion, the study documented that partial substitution of inorganic minerals with a chelated mineral source failed to exert significant effects on performance and total body mineral concentrations. The importance of the influence of sow milk production on mineral body stores in piglets warrants further investigation.

Abstract The study objective was to evaluate absorption differences between different sources of Copper (Cu), Manganese (Mn) and Zin (Zn) in broiler diets. Cobb500 chicks (n = 130, 0-d old) were housed in colony brooders and offered basal diet and water ad libitum for eight days. Following the transition phase, 96 straight-run chicks were randomly assigned to one of 48 battery cages (2 chicks/cage; 12 cages/treatment) and offered one of three soy-corn based diets for three weeks: Negative Control (NC; Basal diet at 6 mg/kg Cu, 35 mg/kg Mn, and 36 mg/kg Zn); Positive Control (PC; NC + 15 mg/kg Cu, 100 mg/kg Mn, and 100 mg/kg Zn from Sulfate sources); Treatment 1 (T1; NC + 15 mg/kg Cu, 100 mg/kg Mn, and 100 mg/kg Zn from hydroxychloride Product 1); and Treatment 2 (T2; NC + 15 mg/kg Cu, 100 mg/kg Mn, and 100 mg/kg Zn from hydroxychloride sources Product 2). Week three birds were bled and dissected to obtain liver, breast and femur samples for mineral absorption status. Data were analyzed using RV3.6.1 procedures with non-repeated measures. Plasma and breast tissue were not (P ≥ 0.05) impacted by mineral source, however numerical increases were reported in PC, T1 and T2 over NC. Liver Cu and Zn concentrations were non-significant (P ≥ 0.05) for all treatments. However liver Mn concentrations increased (P ≤ 0.05) in Pc and T1. Copper bone concentrations were not (P ≥ 0.05) affected, but an increase (P ≤ 0.05) in Mn and Zn was reported for PC, T1 and T2 versus NC. These results indicate increased absorption occurs when mineral sources are adequately supplemented beyond basal diet levels and that source may impact absorption rate. Additional research is needed to address the absorption ability of different mineral sources to better understand the impact on bird performance.

ABSTRACT: This study aimed to evaluate the effect of using lycopene and organic minerals in diets for laying hens on the egg quality and stability of eggs stored for 30 days under different storage environments. An entirely randomized design was adopted in 2x3x3 factorial scheme (mineral sources x lycopene levels x storage periods) with six replicates of eight hens per experimental unit. The experimental diets were: feed containing inorganic minerals (IM) without added lycopene; IM with added lycopene (400mg kg-1); IM with added lycopene (800mg kg-1); organic minerals (OM) without added lycopene; OM with added lycopene (400mg kg-1); OM with added lycopene (800mg kg-1). After 112 days of feeding experimental diets, it was selected 60 eggs treatment-1, which were later labeled, stored in room and refrigerated temperature, and subjected to different storage periods (0, 15 and 30 days). Variables analyzed were: Haugh unit, yolk index, yolk color, albumen and yolk pH, and lipid oxidation (TBARS). Stability of eggs is not altered as a function of mineral sources and levels of lycopene studied. However, increasing storage time affects the quality of the eggs of laying hens at both storage conditions.
