Analisa Kualitas Kimia dan Mikrobiologi Susu Kambing Peranakan Etawa dengan Pemberian Pakan yang Ditambahkan Tepung Kulit Manggis pada Persentase yang Berbeda

Abstract

Dairy goat breeding is an alternative effort to diversify dairy cattle. In increasing milk production, additional ingredients are needed in the feed, one of which is the addition of mangosteen peel flour (Garcinia mangostana L.). The purpose of this study was to determine the chemicals and microbial activity activity of goat milk fed with mangosteen peel flour (MPF). The study was carried out in March - July 2017 at UD Atjeh Livestock, Limpok Village, District of Darussalam, Great Aceh. An experimental study was conducted by using Randomized Block Design (RBD) consisted of 3 groups and 5 treatments, resulted in a total of 15 experimental units. The treatments in this study were consisted of treatment 1 (control, without MPF addition), treatment 2 (with 2.5% MPF addition), treatment 3 (with 5% MPF addition), treatment 4 (with 7.5% MPF addition), and treatment 5 (with 10% MPF addition). Each treatment was done in triplicate, and the obtained data were analyzed by using ANOVA (Variance Analysis). The measured variables include antioxidant activity, protein content, dry matter content, total microbial amount, pH measurement, lactic acid and antimicrobial activity of Etawa crossbreed goat milk fed with mangosteen peel flour. The result showed that mangosteen peel flour addition on Etawa Goats feed did not give significant effect on the levels of milk antioxidants, pH, dry matter, total microbial, lactic acid, and antimicrobials. However, the MPF addition affect milk protein content even though the protein content was still in accordance to the SNI standards. The addition of MPF could increase the antioxidants level up to 5% addition, and increase the milk protein and dry matter content up to 7.5% addition.
