Determination of Routine Nutritional Ingredients and Amino Acid Contents of Jujuncao During Different Growth Stages
To understand the dynamic variation of nutrition and amino acid of different growth stages of Jujuncao,the contents of routine nutritional ingredients and amino acid were determined at the growth stages of 90 d,130 d,170 d and 210 d.Results:Crude protein(CP) content reached the highest(9.19％) after 90 days growth and decreased significantly (P＜0.01) with the growth stage prolonging;The content of crude fiber(CF),neutral detergent fiber(NDF) and acidic detergent fiber(ADF) increased with the growth stage prolonging;The content of NDF and ADF both in 90 days and 130 days were significantly different(P＜0.01) with 170 days and 210 days,the content between 170 days and 210 days was significantly different for NDF but not significantly different(P＞0.05) for ADF.The content of total amino acids in 90 days was 7.069％ and reduced with the growth stage prolonging,both of TAA/CP and TEAA/TAA were of high-low-high change trend.
