Chemical Quality of Longissimus Muscles of Kacang Goat After Supplemented With A Combination of Palm Kernel Meal and Powdered Katuk Leaf

Abstract

The purpose of this study was to analyze the effect of supplementation of palm kernel meal (BIS), Katuk leaf powder (KAT), and their combination on the chemical quality of Longissimus dorsi muscle in Kacang goats. Twenty male Kacang goats aged +1.5 years old with the average live body weight of 15.42±1.28 kg were used in this research. A complete randomized design was used in this research; with 4 treatments and 5 replications. All goats were acclimatized for 2 weeks. Group P0 as control was given distilled water. Group P1 was given BIS at a dose of 100 gr/day/head. Group P2 was administered with BIS 100 gr/day/head and Katuk leaf powder 15 gr/day/head, and group P3 was given KAT 15 gr/day/head. The treatments were given twice per day for 35 consecutive days and goats were fed with leaves and grasses, and had access to water ad libitum. At the day 25 and 50 after treatment, goats were slaughtered according to standard commercial halal procedures. L. dorsi muscles were taken and subjected to measurement of moisture content, crude protein, fat, ash content, and cholesterol. The results showed that KAT statistically (P≤0,05) reduces cholesterol and fat contents of L. dorsi muscles. In conclusion, the administration of KAT may reduce cholesterol and fat.
