Research of production methylselenocysteine feed additives by navel orange residues
The objective of this study was to add an appropriate amount of wheat flour and bacterial activation on the substrate of Navel orange residues,and explore the effect of complex bacteria fermentation on the conversion of sodium selenite into organic selenium(Methylselenocysteine).The study was divided into 6 groups of 6 replicates each.The control group was added with mixture of wheat flour and 1.0%sodium selenite;In the five experimental groups,wheat flour was replaced wheat flour with 57%Navel orange residues at the rate of 0.2%,0.6%,0.8%,1.0%and 1.2%sodium selenite respectively.After mixing 1%of complex bacteria with Navel orange residues,wheat flour etc,each group was fermented at 37℃for 96 hours,then the conversion rate of organic selenium(methylselenocysteine)was tested.Results:Under this experimental conditions,Organic selenium(methylselenocysteine)conversion rate of the experimental groups was significantly higher than the control group(P＜0.05),Organic selenium conversion rate exceeded 99%,Methylselenocysteine conversion rate exceeded 72%,of which the conversion rate of methylselenocysteine in the 5th treatment group was as high as 93.4%.Conclusion:This study provides ideas for the development of organic selenium feed additive based on Methylselenocysteine,to fully realize the resource utilization of agricultural by-products,and provide a high-quality selenium source to meet the physiological needs of animals and produce selenium-rich health food.
