Abstract

The purpose of this study was to obtain the expected values and variation ranges of dry matter (DM), starch (Starch), neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents in whole corn silage based on Meta-analysis, and to explore the effects of ensiling period, regions and harvest time on the nutrient contents of whole corn silage. By searching CNKI, Web of Science and other literature databases, 38 literatures were included according to the inclusion and exclusion criteria, and a total of 273 groups of whole corn silage data were included. The contents of DM, Starch, NDF and ADF in whole corn silage were predicted by reciprocal of variance Meta-analysis, and their influencing factors were explored. The results showed that the content of DM in whole corn silage was 31.33%[95%CI(30.93% to 31.74%)], the content of Starch was 25.51%[95%CI(24.70% to 26.32%)], the content of NDF was 44.18%[95%CI (43.53% to 44.83%)] and the content of ADF was 25.15%[95%CI (24.78% to 25.52%)]; ensiling period had no significant effect on the nutrient content of corn (P>0.05); the contents of DM and Starch in whole corn silage in China were significantly lower than those in the United States (P<0.05) and the European Union (P<0.05), and the contents of NDF and ADF were significantly higher than those in the European Union (P<0.05); the harvest time could significantly affect the nutrient contents of whole corn (P<0.05), with the delay of harvest time, the contents of DM and Starch in whole corn silage gradually increased, and the contents of NDF and ADF decreased. When the harvest time was greater than 3/4 milk line period, the content of NDF in whole corn silage was higher than 2/3 milk line period (P>0.05), while the content of ADF was significantly higher than that in 2/3 milk line stage (P<0.05). In summary, we have obtained the expected value and variation of nutrition composition in whole corn silage, which indicate that the silage quality of whole corn in China is lower than that in the United States and the European Union, and harvest the whole corn at 2/3 milk line stage might be an efficient way to improve the nutritional value of whole plant corn silage in China.
