MILK PEPTIDE MAPPING OF GOAT FED COMPLETE FEED WITH HIGH LINOLEIC ACID CONTENT

S. Romziah, M. Anwar, S.W. Retno

Abstract
Linoleic acid content of complete feed was increased when using corn oil in the processing of complete feed, and itís around 2.691 to 4.736 %. The declined of crude fiber in the complete feed influence by fibrolytic enzyme and or Cellulomonas sp. bacteria adds as the catalyst and or starter during fermentation of complete feed.
Feed intake more efficiently when goat consumed complete feed which containing corn oil and fermented by fibrolytic enzyme and or innoculant Cellulomonas sp. bacteria, and the milk productions and conjugated linoleic acid contents in milk were significantly increased at level about 535,06 to 570,31 ml/h/d and 3,4345 to 4.48%, respectively. Based on isolation of milk peptide, it showed that milk peptide profile of goat fed complete feed with high linoleic acid content has a molecular weight more than 42 kda.

Key words: Complete feed, linoleic acid, molecular weight, goat milk peptide
