“…It is obvious that improvements in efficiency in layer hens fed with the probiotic supplements derive from higher egg mass yield, along with lower feed consumption, compared to the control treatment. In agreement with our findings, a great deal of studies conducted with laying hens has shown that the benefits of probiotic microbials on the feed conversion ratio were substantially different in experimental protocols (Krueger et al, 1977;Hargis and Creger, 1987;Nahashon et al, 1994b;Tortuero andFernandez, 1995, Abdulrahim et al, 1996;Grimes et al, 1997). Interestingly, similar levels of improvement in the feed conversion ratio were obtained when the same probiotic preparation used here (Protexin) was added to layer hens' diets (Balevi et al, 2001;Yörük et al, 2004) It appears that the aforementioned positive correlation between probiotics and nutrient retention in layer hens might play an important role in feed conversion efficiency (Nahashon et al, 1994b,c;Grimes et al, 1997).…”

The performance-enhancing mechanism of microbial cultures may operate on the metabolic process of digestion by increasing enzymatic activity (Jin et al, 2000) and the passage rate of digesta (Dellipiani et al, 1968), as well as by deconjugating bile salts and acids (Brown, 1977;Sung et al, 1990).…”

Aspergillus oryzae mediated increase in metabolizabilities of gross energy and dry matter (Han et al 1999), lipid and protein digestibilities (Grimes et al, 1997) in previous works confirm the improved performance of laying hens treated with Prob-3. Similarly, positive effect of Aspergillus oryzae on the performance of laying hens fed diets with different levels of methionine was also reported (Harms and Miles, 1988).…”

The effect of three probiotic dietary supplements on the laying and reproductive performance of layer hens and broiler breeder hens was investigated. A total of four hundred and eighty, 22-week-old layer hens were given diets containing one of three probiotics (1 g/kg diet for each probiotics) from weeks 22 to 49. Seven hundred and twenty female and sixtyfour male broiler breeders were also subjected to the same additive feeding procedure between 21 and 50 weeks of age. The layer hen and breeder trials were initiated simultaneously and performed in pens located in the same area. Either egg production rate or egg weight was affected by the microbial cultures administered. Body weight and mortality were not affected. Egg production rate, egg weight and egg mass benefited from some of the probiotics, while, overall, the probiotics led to significant improvements in the feed conversion rate of layer hens. All of the probiotic preparations decreased the cracked-to-broken egg ratio, compared to the untreated control group. One of the three probiotic supplements significantly improved the egg production rate and increased the settable egg and chick yield per hen in broiler breeders, whereas, overall, probiotics tended to decrease settable egg weight. Probiotics enhanced hatchability, but no beneficial effects were observed on fertility. Based on these findings, it can be said that the microbial cultures in the probiotic preparations exhibited host-specific and strain-specific differences in their activities as performanceenhancer feed additives, with improvements in some selected performance parameters.

“…Also, synbiotic substantially increased blood glucose but reduced cholesterol while Serum total protein and uric acid also decreased in the all dietary levels of synbiotic compared to control group of the ostrich chicks. Synbiotic has the ability to reduction the concentration of cholesteryl esters CE in LDL-cholesterol [114]. Prebiotic that present in the synbiotic mixture has hypocholesterolemic effects thereby decreasing the absorption of lipids in the intestine through binding bile acids, increasing cholesterol elimination and hepatic synthesis of new bile acid [115].…”

According to the increasing of human population in the world, it reached about seven billion people and it continuously increased. In this background, the food source in both animal and plant origin must be increased accordingly. For these we must use and add some feed additives such as antibiotic, probiotic, prebiotic, postbiotic and synbiotic for the animal feed to increase production (meat, egg, milk and fish) and improve health. In early cases, probiotic as mono or mixed beneficial live microorganism was used as feed additive that plays a significant role in several health conditions and performances. In another way, the scientists use some ingredients indigestible with carbohydrates origin, especially oligosaccharides as a source of energy for beneficial microorganisms in the body which were called prebiotic, and it is indigestible fermented food substrates that stimulate the growth, composition and activity of microorganisms in gastrointestinal and improve host. Most of the scientists urged to use all the above in such way that have more benefits in animal health and performance which were therefore called synbiotic, that was a combination between probiotic and prebiotic which beneficially had significant effects on the host by improving the survival and implantation of live microbial dietary supplements in the gastrointestinal tract, and thus improving animal health and performance. So, it was proposed that the synbiotic in this research increased beneficial microorganisms in the gastrointestinal tract and improved intestinal architect, and then promoted intestine environment. Consequently, it can improve blood indices, and especially decrease bad cholesterol (Low-density lipoprotein), decrease harmful microorganisms and toxins. However, it can also improve ingredient product, increase mineral absorption and nutrient. In conclusion, it can improve animal health and performance.

An experiment was conducted to investigate the dietary effects of a transgenic Aspergillus oryzae(AO) culture on the performance, egg quality and intestinal microflora of layers. A total of 840 Hy-line Brown layers of 39wks old were assigned to one of the following 7 dietary treatments: control(C), C + 0.2% AO culture, C + 0.5% AO culture, C + 0.2% transgenic AO culture, C + 0.5% transgenic AO culture, C + 0.2% transgenic mutant AO culture, and C + 0.5% transgenic mutant AO culture. The transgenic AO was made by inserting Salmonella gallinarum gene to AO. And the transgenic mutant AO was made by inserting Salmonella gallinarum gene to mutant AO which was mutated by UV irradiation. Each treatment was replicated six times with 20 birds housed in 2 bird cage. Twenty birds units were arranged according to completely randomized block design. Feeding trial lasted for 8wks under 16 hour lighting regimen.Laying performance and egg quality were significantly(P < 0.05) affected by the treatments. Transgenic AO culture supplementation at the level of 0.2% significantly increased egg production, while its egg weight was significantly decreased compared to that of the control. Feed intake and feed conversion ratio(FCR) were not significantly different among the AO treatments and the control. The eggshell strength of the AO treatments was significantly higher than that of the control. Transgenic mutant AO culture supplemented at the level of 0.5% significantly increased egg yolk color. Intestinal microflora were significantly(P<0.05) affected by the treatments. The cfu of Lactobacilli spp. significantly increased and those of Salmonella species and E. coli decreased in the AO treatments. The transgenic AO and transgenic mutant AO culture were more effective than the AO culture in reducing the cfu of Salmonella species and E. coli.It is concluded that supplementation of the transgenic AO culture at the level of 0.2% could be recommended for the improvement of egg production. Supplementation of transgenic AO or transgenic mutant AO culture at 0.2% level effectively controlled intestinal Salmonella species population.
