Abstract

The problem that often occurs in the development of beef cattle on smallholder is the low level of livestock productivity, this is because the rearing system implemented is still conventional so that feed requirements have not been met, both in quality and quantity. The study was conducted to determine the values of nutrient content, dry matter digestibility (DMD), organic matter digestibility (OMD), concentration NH3 and efficiency microbial protein synthesis (EMPS) value of beef cattle feed in Bangkalan Regency. This study used an in vitro method assigned in a randomized block design (RBD) with six treatments and three replication. The following three treatments based on feed survey in Bangkalan Regency (A1, A2, A3) and three treatment based on feed scenarios (B1, B2, B3) repectively, feed for Madura heifer, Madura cattle and Limousine crossbred. The results showed that the feed from the survey was of lower quality compared to the scenario feed, especially its protein content. Scenario feed can improved DMD and OMD value and this was closely related to improvements of rumen NH3 concentration with also contributed to EMPS value improvement.
