Efektivitas Ransum Penggunaan Minyak Ikan Lemuru dan Mineral Zn, Fe, Cr terhadap Karkas Non-Karkas Ayam IPB-D1

Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh penggunaan minyak ikan lemuru dan mineral esensial (Zn, Fe, Cr) dalam ransum terhadap kualitas karkas dan non-karkas ayam IPB-D1. Sebanyak 154 ekor ayam IPB-D1 dipelihara selama 12 minggu dengan 4 perlakuan pakan: P0 (2,5% minyak sawit/kontrol), P1 (2,5% minyak ikan lemuru), P2 (2,5% minyak ikan lemuru + 60 ppm Zn + 20 ppm Fe + 0,4 ppm Cr), dan P3 (2,5% minyak ikan lemuru + 120 ppm Zn + 40 ppm Fe + 0,8 ppm Cr). Hasil menunjukkan P3 menghasilkan bobot potong tertinggi dan konsumsi pakan tertinggi. P3 juga menghasilkan pengaruh yang sangat nyata (P<0,01) terhadap persentase karkas. Persentase potongan karkas dan persentase non-karkas tidak berbeda nyata antar perlakuan. Kesimpulan penelitian ini adalah penggunaan minyak ikan lemuru sebesar 2,5% dalam pakan yang dikombinasikan dengan mineral 120 ppm Zn, 40 ppm Fe, 0,8 ppm Cr dalam ransum ayam IPB D1 memberikan pengaruh positif terhadap peningkatan bobot potong dan persentase karkas ayam IPB D1.

This study aimed to evaluate the effect of using lemuru fish oil and essential minerals (Zn, Fe, Cr) in the ration on carcass and non-carcass quality of IPB-D1 chickens. A total of 154 IPB-D1 chickens were reared for 12 weeks with 4 feed treatments: P0 (2.5% palm oil/control), P1 (2.5% lemuru fish oil), P2 (2.5% lemuru fish oil + 60 ppm Zn + 20 ppm Fe + 0.4 ppm Cr), and P3 (2.5% lemuru fish oil + 120 ppm Zn + 40 ppm Fe + 0.8 ppm Cr). Results showed P3 produced the highest slaughter weight and highest feed consumption. P3 also produced a very significant effect (P<0.01) on carcass percentage. Carcass percentage and non-carcass percentage were not significantly different between treatments. The conclusion of this study is that the use of 2.5% lemuru fish oil in feed combined with 120 ppm Zn, 40 ppm Fe, and 0.8 ppm Cr minerals in the IPB D1 chicken ration has a positive effect on increasing the slaughter weight and carcass percentage of IPB D1 chickens.
