Effects of Multi Strain Probiotics on Egg Production and Quality in Laying Hens Fed Diets Containing Food Waste Product

The objective of the present study was to evaluate the effects of multistrain probiotics (MP) supplementation to diets containing 40% food waste product (FWP) on egg production and quality. Forty wk-old Lohmann Brown were allocated to 4 dietary treatments with 5 replicates and 2 birds/cage in completely randomized design. A basal diet formulated to contain corn, soybean meal and FWP and 3 additional diets were prepared by adding 0.1, 0.2, or 0.4% of MP. During the 3-wk feeding period, the addition of 0.4% MP showed the least egg production (75.4%) compared with 0 (85.5%) or 0.2% (81.4%) MP addition (p<0.05), but the egg production was not different between 0.1 and 0.4% MP addition. The BW changes as well as feed intake were not different among the dietary treatments. The BD supplemented with 0.4% MP showed greatest Haugh units (60.4, p<0.05) compared with other treatments. There was no significant difference in yolk color among the treatments with the exception of dietary group with 0.4% added probiotics in which the least Roche color index (8.4, p<0.05) was observed. In conclusion, the present study indicated that the addition of probiotics to diets containing 40% FWP improved the egg protein quality but did not affect productivity of laying hens.
