Abstract

Tujuan penelitian ini adalah untuk membandingkan kualitas ransum buatan dengan ransum komersial terhadap berat pemotongan, berat karkas dan berat lemak abdominal ayam broiler. Penelitian ini menggunakan metode eksperimen dengan melakukan pengujian terhadap perbandingan pada perlakuan ransum buatan dan ransum komersial. Variabel yang diukur pada penelitian ini terdiri dari Berat potong (g/ekor); Berat karkas (g/ekor) dan Berat lemak abdominal (g/ekor). Hasil penelitian menunjukkan bahwa berat potong tertinggi ditunjukkan pada perlakuan Ransum komersial 1772,94 g/ekor lebih tinggi dibandingkan ransum buatan 1761,06 g/ekor atau selisih 11,88 g/ekor, Pada berat karkas tertinggi yaitu pada perlakuan ransum komersial 1584,03 gr/ekor lebih tinggi dibandingkan ransum buatan 1573,37 g/ekor atau selisih 10,66 g/ekor, pada berat lemak abdominal tertinggi pada perlakuan ransum komersial 27,37 g/ekor dibandingkan ransum buatan 9,94 g/ekor atau selisih 17,44 g/ekor. Hasil uji t menunjukkan bahwa pada variabel berat potong dan berat karkas menunjukkan tidak berbeda nyata (p>0,05) antara ransum buatan terhadap ransum komersial atau dengan kata lain kedua perlakuan memiliki kualitas yang sama sedangkan pada variabel lemak abdominal menunjukkan perbedaan nyata (p<0,01) hal ini menunjukkan bahwa ransum buatan menghasilkan lemak lebih sedikit dibanding ransum komersial. Dapat dikatakan bahwa kualitas ransum buatan sama baiknya dengan ransum komersial namun lebih baik pada lemak abdominal.©2016 dipublikasikan oleh JAS.

Abstract

The purpose of this study was to evaluate the effect of using cosmos caudatus Kunth flour (stem + leaves) on the internal quality of laying eggs. This research has been conducted in Bacem Village, Sutojayan District, Kab. Blitar. This study uses an experimental method with a completely randomized design (CRD) consisting of 4 treatments and 6 replications. Treatment P0 = Basal feed + 0% flour (stem + leaves) cosmos caudatus Kunth, P1 = Basal feed + 0.25% flour (stem + leaves) cosmos caudatus Kunth, P2 = Basal feed + 0.50% flour (stem + leaves) cosmos caudatus Kunth, P3 = Basal feed + 0.75% flour (stem + leaves) cosmos caudatus Kunth. The parameters observed were the weight of the egg white, the proportion of egg white, the weight of the egg yolk, the proportion of the yolk and the score of the yolk color. The results showed that the administration of flour (stem + leaves) cosmos caudatus Kunth plant as a feed additive can provide a very significant effect (P <0.01) on the weight of egg white, and no significant effect (P> 0.05) on the proportion of egg white, weight egg yolk, proportion of egg yolk and egg yolk color score. The results of this study it can be concluded that the administration of flour (stem + leaves) cosmos caudatus Kunth as a feed additive can affect the quality of internal eggs.

Abstract

This study aims to determine the extent to which parts of the kenikir plant have the inhibitory power of salmonella sp, escherichia coli bacteria and evaluate the active compounds of flavonoids, polyphenols and saponins that have the potential as feed additives. This research was carried out at the Laboratory of Plant Pests and Diseases, Faculty of Agriculture, Universitas Brawijaya and the Laboratory of Metria Medica Batu Malang on October 22, 2018. This study used an experimental method with a completely randomized design (CRD) consisting of 4 treatments and 6 replications. Treatments P0 (bacterial isolate + Aquades 30 %), P1 (bacterial isolate + 30% kenikir leaf powder concentration solution), P2 (bacterial isolate + 30% kenikir stem flour concentration solution), P3 (bacterial isolate + Leaf and stem flour concentration solution cringe 30%). The parameters observed were the inhibition of kenikir flour plant parts against Salmonella sp., Escherichia coli bacteria and evaluation of the active compounds of flavonoids, polyphenols and saponins from kenikir plant flour. The results showed that the effect of differences in flour from the part of the kenikir plant on the inhibition of bacteria was very significant (P<0.01) on Salmonella sp and Escherichia coli bacteria.
