This study was designed to investigate whether inclusions of humate and probiotic into diets of hens during the late laying period increases egg production and improves egg quality. Hisex Brown layers (n = 300), 54 wk of age, were fed a control diet, 0.1% humate, 0.2% humate, 0.1% probiotic, or 0.2% probiotic for 75 d. Active ingredients of humate and probiotic were polymeric polyhydroxy acids (humic, fulvic, ulmic, and humatomelanic acids) and bacterial cultures (Lactobacillus, Bifidobacterium, Streptococcus, and Enterococcus spp.), respectively. Egg production and feed intake were measured daily, and egg weight was measured biweekly. Also, a sample of 12 eggs from each group was collected randomly to determine egg quality every 25 d. The data were analyzed as repeated measures with time as subplot. There were no effects of dietary treatments on feed intake and egg weight. Egg production for hens supplemented with humate and probiotic was not different but was greater than for control hens. Egg production increased linearly and mortality and feed conversion efficiency (weight of feed/weight of eggs) decreased linearly with increasing levels of supplemental humate and probiotic. There were no effects of treatments on egg quality. In conclusion, supplementation of humate and probiotic during the late laying period increased egg production, reduced mortality, and improved feed conversion efficiency but did not improve egg quality. |
