Growth and carcass production responses of EPMp broiler ducks to various levels of crude fiber and protein in the diet

Abstract

Purba M, Prasetyo LH. 2014. Growth and carcass production responses of EPMp broiler ducks to various levels of crude fiber and protein in the diet. JITV 19(3): 220-230. DOI: http://dx.doi.org/10.14334/jitv.v19i3.1085Inclusion of crude fiber in diet is important for duck growth, but there is a limit in its use in order for the ducks to grow normally. The purpose of this study was to evaluate growth and carcass production responses of EPMp broiler ducks under different levels of crude fiber and protein in diets. Four hundreds and twenty day old ducklings were allocated into 7 treatments with 6 replications and each replication consisted of 10 ducks. The treatments were the factorial combinations of crude fiber content of 6 or 9% and protein content of 19, 21, or 23%; and BR-1 (starter diet) as positive control. The variables observed were: feed intake, weekly body weight, and percentage of carcass production. The results showed that all variables observed were not significantly affected by CF content, but highly significantly affected by crude protein levels in diet. Protein content of 19 or 21% in diet resulted in a better performance for EPMp ducks. The inclusion of high CF in diet did not affect carcass percentage, except for reduced abdominal fat. The study implies that administration of high CF (6 or 9%) with a protein content of 19 or 21% in the diet are still acceptable to EPMp ducks at 12 weeks. Penyertaan serat kasar dalam pakan sangat penting untuk pertumbuhan itik, namun ada batas penggunaannya agar itik tumbuh dengan normal. Tujuan penelitian ini adalah untuk menguji respon pertumbuhan dan produksi karkas itik pedaging EPMp dengan pemberian serat kasar tinggi pada level protein yang berbeda dalam pakan. Empat ratus dua puluh ekor itik umur sehari dipelihara selama dua belas minggu dan dialokasikan ke dalam 7 perlakuan dengan 6 ulangan dan setiap ulangan terdiri dari 10 ekor itik. Susunan ransum perlakuan merupakan kombinasi factorial antara kadar serat kasar 6 atau 9% dan kadar protein 19, 21 atau 23%; dan BR-1 (pakan starter) sebagai kontrol positif. Peubah yang diamati mencakup: konsumsi pakan, bobot badan mingguan dan persentase produksi karkas. Hasil penelitian menunjukkan bahwa konsumsi pakan, pertambahan bobot badan, bobot badan akhir dan FCR tidak nyata dipengaruhi oleh pemberian SK tinggi dalam pakan, akan tetapi sangat nyata dipengaruhi oleh kadar protein dalam pakan. Kadar protein 19 dan 21% dalam pakan menghasilkan performa yang lebih baik pada itik EMPp umur 12 minggu. Persentase bobot karkas itik tidak nyata dipengaruhi oleh kadar SK dalam pakan akan tetapi nyata untuk bobot lemak abdominal itik. Pemberian SK tinggi tidak nyata berpengaruh terhadap performa itik, akan tetapi nyata menurunkan bobot lemak abdominal. Dari hasil dapat disimpulkan bahwa pemberian SK tinggi 6 atau 9% dengan kandungan protein 19 atau 21% dalam pakan masih dapat diterima oleh itik pedaging EPMp umur 12 minggu.Kata Kunci: Itik Pedaging EPMp, Serat Kasar, Performa, Karkas PENDAHULUANSalah satu masalah utama ...

The Effect of Soursop (Announa Muricata L.) Leaves Powder on Diameter of Muscle Fiber, Lipid Cell, Body Weight Gain and Carcass Percentage of Tegal Duck

“…It showed that as the ducks get mature, the back percentage is not significantly increased or relatively similar. The back percentage of this research was 14.27%, similar to 17.47% of 12-week Tegal duck (Purba and Prasetyo, 2014) and 14.3±05% and 14.7±0,4% of male and female Gemba duck, respectively (Matitaputty and Bansi, 2016).…”

“…However, analysis of variance showed that soursop leaves meal supplement did not significantly affect (P>0.05) wing percentage since the percentage yield was relatively similar. Averaged carcass percentage on wings in this research was 9.66% while Purba and Prasetyo (2014) reported 11.05% on 12-week Tegal duck.…”

“…However, Purba and Prasetyo (2014) reported that high crude fiber in feed did not significantly affect (P>0.05) the weight of duck leg. Similar result was obtained in ducks' proportional weight of back and wings meat.…”

Performa Tiga Genotipe Itik Pedaging (Peking, PMp dan E-PMp) dengan Pemberian Dua Jenis Ransum selama Enam Minggu

“…Secara biologis itik E-PMp memiliki (mewarisi) sifat dari tiga genotipe induknya yakni entog, itik Peking dan itik Mojosari putih. Sifat-sifat unggul yang dimiliki itik E-PMp antara lain pertumbuhannya cepat, ukuran tubuh besar dan memiliki otot atau daging yang tebal, warna bulu bervariasi (campuran warna bulu putih dan hitam), bobot karkas tinggi dan warna karkas putih bersih (Purba & Prasetyo 2014). Ketiga genotipe itik tersebut dipelihara dan diseleksi dengan intensif untuk menghasilkan turunan yang unggul.…”

Effect of Different Lysine and Energy Levels in Diets on Carcass Percentage of Three Strains of Broiler Duck

“…PMp duck was a dual purpose duck as for meat production and eggs production. The EPMp ducks has a rapid growth, large body size and thick muscle or flesh, with plumage color vary (mixed white and black), high carcass weight with clean and white skin (Purba & Prasetyo 2014). Pekin duck was imported broiler ducks, which has been long maintained in various regions in Indonesia.…”
