The effect of vitality mineral liquid complex on production performance, nutrient digestibility, blood characteristics, egg quality and excreta microflora in laying hens

Abstract Text: A total of 360 Hy-line brown laying hens (40-week-old), were used in this 5-wk experiment to evaluate the effect of vitality mineral liquid complex on production performance, nutrient digestibility, blood characteristics, egg quality, and excreta microflora in laying hens. Laying hens were randomly allocated into 5 dietary treatment groups which consisted of: 1) CON (normal water), 2) I2 (pH 2.2, Ion water), 3) P2 (pH 2.2, polymerization water), 4) I3 (pH 3.0, Ion water), and 5) P3 (pH 3.0, polymerization water). In this study, feed intake and egg broken rate was unaffected (P>0.10), but egg production was increased in I3 and P3, respectively, when compared to CON treatment (96.63, 96.45 vs. 94.55; P < 0.05) at wk 3, egg production in P3 was higher (96.85 vs. 94.74; P < 0.05) than CON treatment at wk 5. Nutrient digestibility of the Ca in P2, I3, and P3 treatment, resepectively, was higher (56.50, 57.58, 55.27 vs. 51.15 %; P < 0.05) than CON treatment. The blood profile of calcium counts was increased (26.05, 27.23, 27.70 vs. 22.45; P < 0.05) in P2, I3, and P3 treatments compared with CON treatment and phosphorus counts was improved (5.28 vs. 4.58; P < 0.05) in I3 treatments compared with CON treatment. Moreover, effect of vitality mineral liquid complex improved the eggshell thickness (40.44 vs. 39.72 mm^-2; 40.59 vs. 39.68 mm^-2; P < 0.05) with P3 treatment at 4 and 5 weeks of trial. The inclusion of I3 and P3 diets showed a lower (2.24, 2.19 vs. 2.40 log₁₀cfu/g; 6.24, 6.20 vs. 6.50 log₁₀cfu/g; P < 0.05) amount of excreta Salmonella and E.coli counts compared with CON diets. Our results indicated the vitality mineral liquid complex improve the egg production, calcium, phosphorus counts in blood, and decrease the Salmonella and E.coli counts in laying hens.
