Abstract


Background: For dairy cattle, high milk production relate closely with feed quality intake especially protein content. Protein usage could be seen from nitrogen retention point of view.  Furthermore N retention for each feedstuff is inflenced by its energy content. N retention in tissue is determined by energy supply and N. Research was conducted to study pollard and bran into feed digetibility, and correlation between N retention with milk production.

Method: Eight dairy cattle in 2-3 lactation period with 310-504 kg body weight were used as research material. Cross Over Design used for this reseach, 15 days as preliminary for feed adaptation and 15 days for collected data (10 days for feces collection and 5 days for urine) for each periode. Measured parameter included feed digestibility (dry matter, organic matter, and crude protein), and milk production. 

Result: Research showed that treatment have non significant (P>0,05) into dry matter and organic matter digestibility, but gave significant (P<0,05) effect into crude protein digestibility.  The usage wheat pollard gave betterdigestibility than rice bran, especially at digestible crude protein. Fourty percent in average of milk production was influenced by nitrogen retention
