Perbandingan Suplementasi Tepung Kunyit dan Campuran Tepung Kunyit plus Ekstrak Daun Katuk Fermentasi terhadap Performa, Mutu Karkas dan Komposisi Gizi Daging pada Broiler

Abstract

This study aims to compare two feed additive formulas on the performance and quality of broiler meat. Forty broiler chickens were distributed into 2 groups. Each treatment group consisted of 4 replications, and each replication consisted of 5 broiler chickens. The 2 treatments were as follows: 1) broiler chickens fed diet contained with 4.5 g Fermented Sauropus androgynus leaf extract (FSALE) plus 4.5 g turmeric powder (TP)/kg diet (P1) and; 2) broiler chickens fed diet contained with 9 g TP/kg diet (P2). The results showed that two feed additive formulas had no significant effect on body weight, feed intake, feed conversion ratio, carcass weight, meat bone ratio, cooking loss, meat color, odor, taste and texture, protein, fat, cholesterol, carotene, isoleucine, leucine, lauric acid, miristic acid, palmitic acid, stearic acid, linoleic acid, linolenic acid and eicosapentaenoic acid of meats, but significant affected carcass color, and drip loss and iron content (P <0.05), aspartic acid, glutamic acid, serine, glycine, histidine, arginine, threonine, alanine, proline, tyrosine, valine, methionine, cystine, phenylalanine and lysine (P <0.01), oleic acid and docosahexaenoic acid of meats (P <0.05). It can be concluded that formula 1 (mixed FSALE + TP) produced meat with lower drip loss, better iron content, better amino acid composition and lower levels of saturated fatty acids.
