Unsaturated Fatty Acid Content of Milk from PE Goat Fed with Palm Oil Sludge Meal and Tea Waste Combination

Abstract

This experiment was conducted to study the effect of Palm Oil Sludge Meal (POSM) and Tea waste (TW) combinations (25%) in the ration (78% TDN; 23% CP) containing field grass (30%) and tempe waste (45%) on PE goat nutrient intakes, milk production, composition and unsaturated FA concentrations. Treatments were combination ratio between POSM and TW i.e: RO= POSM 25% + TW 0% (l : O); RI = POSM I6.67% + TW 8.33% (I: 0.5); R2 = POSM 14.28% + TW 10.72% (I : 0.75), and R3 = POSM I2.25% + TW I2.25% (1 :1). Results showed that the treatments did not affect feed and nutrient intakes, and milk composition (dry matter, density, fat and solid non fat); however, the treatment effect on unsaturated FA concentrations was significant (P<0.05). Rl produced milk with the highest concentrations of oleic (37.73%) and linoleic (7.53%) acids, while R3 yielded the highest concentration oflinolenic acid (2.79%). As conclusion, feeding PE goat with I6.67% POSM and 8.33% TW (RI) produced the best combination in increasing milk unsaturated FAs concentration.
