0.05). In the second addition of different aluminosilicate adsorbents significantly reduced the rate and potential of gas production. Likewise, dry matter digestibility and ammonia nitrogen concentration reduced significantly (P<0.05). Significant increase in pH of the culture medium by addition of aluminosilicate adsorbents can be attributed to the fact that aluminosilicate acts as a modifier of hydrogen ion in the environment due to the replacement of cations with hydrogen ion and prevents a significant decrease in rumen pH. Probably lowering the ammonia nitrogen concentration is due to the fact that the protozoan population is affected by aluminosilicate adsorbent and decreases; consequently, the population of the ruminal bacteria increases, which results in the removal of more ammonia nitrogen by microorganisms, and ultimately the concentration ammonia nitrogen decreases in the rumen.
Conclusion: The results of this study showed that AFB1 reduced gas production rate (c), the gas production potential (b), the concentration of ammonia and digestibility, but the pH is not affected in vitro. Also, none of the adsorbents was able to neutralize or reduce the negative effects of AFB1 on the parameters of gas production, fermentation and rumen digestion, which could be due to the absorption mechanism of aluminosilicate adsorbents for AFB1 absorption. The results of this study indicate that adsorbents cannot reduce the negative effects of AFB1 on digestion and rumen fermentation, therefore only proposed strategy is to prevent the contamination animal feed with mycotoxins.]]>

0.05). Birds receiving organic selenium along with vitamin E in their diets had low feed intake compared to other treatments and their feed conversion ratio numerically decreased and intended to significant (p<0.1).The organic selenium plus vitamin E improved the height of white, HU units, yolk pH, and yolk index compared to control group. Egg quality parameters including yolk index and shell surf index in inorganic selenium group were significantly higher than control group (p<0.0.05). Egg yolk selenium was increased in organic and organic selenium (2.06, 1.31 mg/kg) compared to control (0.36), which is a better value from the nutritional viewpoint. Blood cholesterol and triglyceride levels were not affected by experimental diets. Concentration of yolk MDA was highest in control and lowest in organic selenium group during storage (P < 0.05). The result of this study showed that egg production, feed conversion ratio and total egg mass were not affected by experimental treatments. This was also observed by other researchers who evaluated the dietary inclusion of vitamin E. In another one egg quality parameters, however, egg weight was significantly raised after being fed with a diet contained 120 mg kg-1 of vitamin E and 0.4 mg kg-1 of organic selenium.Conclusion: In conclusion, our study data revealed dietary organic selenium and vitamin E, could improve the egg quality during storage and increased egg yolk selenium of Japanese quails. ]]>
