Horticultural byproducts may provide nutrients for poultry if probiotics can increase digestion of complex carbohydrates. White Leghorns (64 layers at 65- to 74-wk-old) were fed (1) a corn/soy Control, (2) Control + 20% sunflower seed meal (SFM), (3) Control + Probiotics (Lactobacillus plantarum, rhamnosus, and paracasei - each at > 23.3 Mil CFU/g for approximately 70,000,000 Mil CFU/g in chlorinated drinking water), and (4) Control + 20% SFM + Probiotics for four weeks. Significance (P < 0.05, < 0.10) for 4 diets x 4 replications x 4 layers per replication was determined for measurements. Diet did not affect production; fluctuations caused trends for FCR (Probiotics*Week) and feed intake (SFM*Probiotics*Week). SFM increased egg weight, decreased specific gravity, and caused a downward trend for shell thickness. SFM*Week caused temporal changes in specific gravity. Probiotics increased egg and shell weight while decreasing shell thickness; Week produced fluctuations for specific gravity. SFM, SFM*Week, Week, and SFM*Probiotics*Week increased yolk color. Temporal changes occurred by Week and SFM*Week for internal measurements and the Haugh unit, respectively. Future research should assess use of fiber types, digestibility of SFM/Probiotic diets, and colonization of the gut after probiotics in water or feed are fed to various types and ages of layers.
