不同谷物日粮对晋南牛瘤胃发酵、养分消化及血液指标的影响
Effects of different grain diet on ruminal fermentation,nutrient digestibility and blood parameters in Jin-nan cattle
摘要
Abstract
[Objective]This study was aimed to investigate the effect of different grain diets on ruminal fermentation,nutrient digestibility and serum parameters in Jinnan cattle.[Methods]The main fodder crops of northern China,including maize, wheat and sorghum,were used as food materials,and Jinnan cattle,the unique cattle breeds in Shanxi province,were served with three different diets using 3 × 3 Latin square experimental design.The effects of different diets on cattle were meas-ured at certain time interval.[Results]Apparent digestibility of NFE of beetle fed on corn or wheat grain was significantly higher than that in sorghum treatment(P<0.05),while the apparent digestibility of ADF and NDF in both corn and sor-ghum treatments were statistically greater than wheat treatment(P<0.05).Apparent digestibility of DM,OM,CP,and EE in all treatments was not significantly affected by different grain diets(P>0.05).The concentration of acetic acid in sor-ghum treatment was significantly higher than that in corn and wheat groups(P<0.05),and the concentration of propionic acid in wheat group was significantly increased compared to that in corn and sorghum groups(P<0.05).Sorghum treat-ment produced the highest acetic acid to propionic acid ratio(P<0.05).Serum total protein of cattle fed on wheat or sor-ghum were significantly higher than those fed on corn(P<0.05),but there was no dietary effect on glucose,albumin,cho-lesterol,and triglyceride in Jinnan cattle.[Conclusion]In conclusion,different grain diets produced specific nutritional char-acteristics in cattle and corn provided better dietary effect on cattle's developmental system than another two tested grains A complementary function was observed between wheat and sorghum diets in ruminal fermentation and nutrient digestibility. Therefore,combination of wheat and sorghum as fodder for Jinnan cattle could be an alternative to corn diet.关键词
