【摘要】：该试验旨在研究镰刀菌毒素对全价饲粮发酵pH、粗蛋白、钙和磷的影响。试验分为3个组,对照组为基础饲粮,试验1组和试验2组分别用25%和50%含有镰刀菌素玉米和玉米蛋白粉代替基础饲粮中的玉米和玉米蛋白粉。采用复合菌种(乳酸菌、酵母菌和枯草芽孢杆菌分别为6.33×10~6 cfu/g、1.05×10~6 cfu/g和8.94×10~6 cfu/g)对全价饲料粮进行固态发酵,发酵开始前所有处理饲粮水分调节至50%。试验结果表明:1)饲粮pH随着发酵时间呈线性下降(P0.05),而粗蛋白(CP)、Ca和P则随着发酵时间呈线性升高(P0.05),但是不同处理的线性斜率差异不显著(P0.05)。2)饲粮(0 d)的pH随着镰刀菌毒素水平的提高而显著降低(P0.05),而镰刀菌素饲粮Ca含量显著高于对照组(P0.05)。发酵末期(18 d)的pH和Ca对照组显著低于25%和50%毒素组;而对照组的CP含量显著高于50%镰刀菌素组(P0.05)。该试验条件下镰刀菌毒素能显著的影响全价饲粮发酵参数pH、粗蛋白、钙和磷的水平。
[Abstract]:The purpose of this study was to study the effects of fusarium toxin on the pH, crude protein, calcium and phosphorus of complete diet. The experiment was divided into 3 groups, the control group was the basic diet, and the experiment group and the test group 2 used 25% and 50% respectively to contain the fusarium and the corn protein powder in place of the corn and the corn protein powder in the basic diet. The whole feed was fermented by the compound strain (6.33,10-6 cfu/ g, 1.05-10-6 cfu/ g and 8.94-10-6 cfu/ g, respectively). The results showed that (1) The pH of the diet decreased linearly with the time of fermentation (P0.05), while the crude protein (CP), Ca and P increased linearly with the time of fermentation (P0.05). However, the difference of the linear slope of the different treatments was not significant (P0.05).2) The pH of the diet (0 d) decreased significantly with the increase of the level of the fusarium toxin (P0.05), while the Ca content of the fusin diet was significantly higher than that in the control group (P0.05). The pH of the end of the fermentation (18d) and the Ca control group were significantly lower than that of the control group (25% and 50%), while the CP content in the control group was significantly higher than that of the 50% Fusarium group (P0.05). The results showed that the fusarium toxin could significantly affect the pH, crude protein, calcium and phosphorus levels of the complete diet.
