Abstract

Microbial growth and various fertnentation processe5in th~ rumen require an adequate supply of minerals. An experiment was conducted to determine rumen fluid characteristics from 20 goats of local breed. ~ f They were randomly allocated into 4 treatments in a Randomized Block Design with 5 replication. Treatments were: A =forages (natural grasses, gIiricidia and leucaena) and concentrate (rice brand, com graL,,\ and coconut meal) ; B =ration A+Ca+P ; C =ration A+Ca+P+Mg and D = ration A+Ca+P+S. Ration between forages and concentrates is 60 : 40 with TDN 53.94% and CP 13.87%. The result showed that there were no effect of mineral
