Abstract

The research was conducted to investigate the effect of ration containing protected pufa fatty acids and fermented waste market on chemical composition of dairy milk. The research employed 15 female PFH dairy cows of 2.5-4.5 years old with body weight 300-400 kg. The research was assigned in randomized complete block design. The treatment consisted of P0= control ration, P1=P0 +50% fermented market waste, P2=P1+ 1000 ppm l-carnitine, P3=P2+ 5% protected tuna fish oil , and P4=P2+ 5% protected lemuru fish oil The results showed that the effects of rations significantly (P<0.01) decreased feed consumption, cholesterol, low density lipoprotein, and saturated fatty acids. Meanwhile it increased milk production, High Density Lipoprotein, omega-3, omega-6 and unsaturated fatty acids in the dairy cow milk. It is concluded that the inclusion of 4% protected fish oil in the rations can produce healthy milk by decreasing milk cholesterol and increasing omega-3, omega-6 fatty acids content.
