| Popis: | This experiment was conducted to investigate and compare the effects of dietary probiotic and prebiotic with sesame meal processed by bio-fermentation technique (SMP) on production performance, blood metabolites, and gut microbiota population in laying hens. A total of 200 Hy-Line W-36 laying hens, 43-wk-old, were randomly allocated to four experimental treatments with five replicates and ten hens per replicate. Experimental treatments were as follows: 1) corn-soybean meal diet (as control diet; [CON]), 2) control diet + 0.1% probiotic (PRO), 3) control diet + 0.1% prebiotic (PRE), and 4) a diet without additives, in which SMP replaced part of the soybean meal in the control diet (SMP). The bio-fermentation process decreased the pH, phytic acid, and crude fiber and increased the crude protein content and the number of lactic acid bacteria (LAB) in sesame meal (P < 0.05). The feeding trial results showed that hens fed diets containing SMP and PRO had better egg production, egg mass, and feed conversion ratio compared to other treatments (P < 0.05). Lactic acid bacteria population and pH in the crop of birds that received PRO and SMP were higher and lower than in other birds, respectively (P < 0.05). Hens fed diets containing SMP, PRO, and PRE had greater LAB populations and lower coliform count in the ileum and cecal than those fed the CON diet (P < 0.05). Feeding diets containing tested feed additives and SMP decreased serum concentrations of cholesterol and triglycerides (P < 0.05). In summary, the results indicated that using SMP in laying hens' diet improved laying production, gut microbiota balance, and serum lipid profile. Therefore, it can be concluded that bio-fermentation, in addition to providing the possibility of replacing dietary sesame meal for soybean meal in laying hen diets, can be applied as a strategic tool for promoting gastrointestinal hygiene and health in birds. |
