| 总结: | Three experiments were conducted at the Dairy Farm,
Department of Animal Sciences, Universiti Pertanian Malaysia,
Serdang, using four cross-bred dairy bulls, Jersey O X Local
Indian Dairy O. The main objective of the study was to evaluate
the effect s of nitrogen fertilization and supplementation with
urea and leucaena on the nutritive value and utilization of
Setaria sphacelata var. splendida in cattle. The indices measured
included rumen degradability, in vivo digestibility, feed intake
and the concentration of ammonia-N in the rumen liqour. In the
balance studies, nitrogen intake and nitrogen balance were
determined.The results of Experiment I showed that the yields of dry
matter and nitrogen of the fertilized were higher than those of the unfertilized forages , but the response ( kg per kg nitrogen
applied ) in both dry matter and nitrogen was decreasing with
increasing nitrogen fertilization. |
