ABSTRAKPenelitian ini bertujuan untuk mengetahui keragaman gen hormon pertumbuhan (GH) dengan enzim MboII pada itik Sikumbang Janti dengan menggunakan penciri PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism). Penelitian ini menggunakan sebanyak 50 sampel darah itik Sikumbang Janti. Sampel darah itik Sikumbang Janti diambil melalui vena achilaris sebanyak ± 1 ml. DNA sampel darah diisolasi menggunakan protocol Genomik DNA Purification Kit (Promega). DNA total diamplifikasi menggunakan sepasang primer F : 5'-CTG GAG CAG GCA GGA AAA TT-3' dan R: 5'-TCC AGG GAC AGT GAC TCA AC-3' yang menghasilkan fragmen exon 1 gen GH dengan panjang 801 bp.
ABSTRACT
This study aimed at determinating the gene diversity of growth hormone (GH) by the enzyme MboII identifier at ducks of Sikumbang Janti using PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism). This study used 50 blood samples of Sikumbang Janti ducks, taken through a vein achilaris as much as ± 1 ml. DNA blood samples were isolated using the protocol Genomic DNA Purification Kit (Promega). Total DNA was amplified using primer pair F: 5'-CTG CAG GCA GGA GAG AAA TT-3 'and R: 5'-TCC AGG TCA GAC GAC AGT AC-3' which resulted in exon
Penelitian ini bertujuan untuk mengetahui pengaruh pemberian tepung kunyit dalam ransum terhadap karkas itik lokal. Penelitian ini menggunakan 80 ekor DOD itik Pitalah jantan yang ditempatkan pada 20 unit kandang boks. Metode penelitian secara eksperimen menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan dan 5 kelompok bobot badan sebagai ulangan. Perlakuan yang diberikan dalam penelitian ini adalah A (tanpa pemberian tepung kunyit/kontrol), B (pemberian tepung kunyit 0,2%), C (pemberian tepung kunyit 0,4%) dan D (pemberian tepung kunyit 0,6%). Peubah yang diamati meliputi bobot karkas, persentase bagianbagian karkas (dada dan paha) dan persentase karkas. Hasil penelitian menunjukkan pemberian tepung kunyit dalam ransum berpengaruh tidak nyata (P>0,05) terhadap bobot karkas, persentase bagianbagian karkas (dada dan paha) dan persentase karkas. Berdasarkan hasil penelitian dapat disimpulkan bahwa pemberian tepung kunyit sampai dengan level 0,6% dalam ransum tidak mempengaruhi bobot karkas, persentase bagianbagian karkas (dada dan paha) dan persentase karkas.
Bird flu infection processes within a poultry farm are formulated mathematically. A spatial effect is taken into account for the virus concentration with a diffusive term. An infection process is represented in terms of a traveling wave solutions. For a small removal rate, a singular perturbation analysis lead to existence of traveling wave solutions, that correspond to progressive infection in one direction.
This study aims to determine the performance of ducks on the effect of differences in cage temperature. This study used 54 5-week-old male ducks selected from 66 ducks. The research method used was randomized block design (RBD). The treatment used is the regulation of the temperature of the cage which is divided into three temperature levels, namely: A (cold temperature), B (room temperature), and C (hot temperature). The observed variables were duck performance in the form of feed consumption, body weight gain and feed conversion. The results of this study indicate that the difference in temperature of the cage became a very significant (P<0.01) on the consumption of rations, weight gain and conversion. The results of the study concluded that the maintenance of ducks at three different cage temperatures had a very significant (P<0.01) on feed consumption and body weight gain, but had no effect on feed conversion. The best results were found in the temperature of the cold cage with the consumption of rations of 2964.33 g/head, which resulted in body weight of 711.83 g/head of g/head, and conversion of 4.2. While the body weight of 1437 percentage of carcass was 67.64% in the study. The highest yield IOFC results (income over feed cost) cage in cold temperatures with a profit of Rp. 3,375.15/head. The maintenance of ducks at three different cage temperatures had no significant effect (P>0.05) on the weight of the spleen, thyroid and kidney and the work of the spleen, thyroid and kidney organs was still normal
