Abstract

The aim of this study was to compare the ruminal degradation characteristics of dry matter (DM) and neutral detergent fiber (NDF) in maize silage feed in dairy farms around Beijing. Three healthy Holstein dairy cows with permanent rumen fistulas were used as experimental animals. Ruminal degradation rate and characteristics of DM and NDF in 72 h in maize silage feed in 9 dairy farms in Changping, Yanqing and Fangshan (3 farms per district) were determined by nylon bag method. The results showed as follows:1) the average value of DM content in maize silage feed in dairy farms in Fangshan was the highest, but those of NDF and acid detergent fiber (ADF) were the lowest; the average values of DM contents in maize silage feed in dairy farms in Changping and Yanqing was close, that of ADF content in dairy farms in Yanqing was the highest, and that of NDF content in dairy farms in Changping was the highest. 2) Dairy farm No. 2 in Changping had the highest effective degradation rate of DM in maize silage feed, which was 38.47%; dairy farm No. 3 in Fangshan had the lowest effective degradation rate of DM in maize silage feed, which was 28.91%; the difference between these two districts was significant (P<0.05). 3) Dairy farm No. 1 in Yanqing had the highest effective degradation rate of NDF in maize silage feed, which was 30.18%, and dairy farm No. 2 in Fangshan had the lowest value, which was 19.63%; the difference between these two districts was significant (P<0.05). In conclusion, the degradation characteristics of maize silage feed in different dairy farms around Beijing are different; it is required that balanced diets should be formulated based on nutrient requirement of dairy cows at different growth, development and lactation stages, combined with the actual nutrient composition.
