This research purpose to observe the response of local duck, especially male duck that given African Leaf Flour (ALF) in the diet, toward body weight and blood cholesterol content. The treatment for this research will be given by differentiate the ALF level in five levels (0%, 0.5%, 1.0%, 1.5%, and 2.0%) with four times replication. This research used Completely Randomized Design. This treatment is obsessed to 80 male ducks which are rearing from the age of 4 until 10 weeks. The result showed that the increasing of ALF level in diets, will highly significant increase the body weight growth (BWG) of duck, as the increasing value of BWG is 23.59% (P<0,01), and its similarly with the Feed Conversion Ratio (FCR). The blood cholesterol content is decreasing to 7.41% for 1.5% the ALF level given (P<0,01), while the content of cholesterol-HDL and LDL has not significantly (P>0,05). However, the content of cholesterol-HDL in blood tend to increase along with the increasing of the ALF level given. Utilization of ALF level until 2.0% could increase the quality of local duck meat, because its produce higher meat production and improve the content of cholesterol for creating healthy animal food sources.

PENGARUH PENAMBAHAN JERINGAU (Acorus calamus) KEDALAM RANSUM TERHADAP KONSUMSI RANSUM, PERTAMBAHAN BERAT BADAN, DAN KONVERSI RANSUM AYAM BROILER Veni Valentino; P.N Jefri; Fridarti Fridarti

Meskipun penggunaan antibiotik diizinkan secara legal namun organisasi kesehatan mulai menentang penggunaannya. Untuk itu perlu dicari ransum alternative untuk mengatasi hal tersebut, salah satunya dengan menggunakan Jeringau.karena mengandung Minyak Atsiri yang bersifat antioksidan, anti-fungi, anti-virus, anti-protozoa, anti-bakteri, dan anti inflamasi. Saponin yang dikandungnya diketahui dapat meningkatkan pertumbuhan dan efisiensi ransum, serta meningkatkan kualitas daging ternak. Kandungan Flafonoid yang dimilikinya bersifat menambah nafsu makan, dan mengurangi asupan pakan. Ketiga zat kimia ini adalah zat yang tidak tercerna sehingga diharapkan dapat menggantikan penggunaan growth promotor komersil dalam ransum. Berdasarkan hasil penelitian dan pembahasan dapat disimpulkan bahwa penambahan Jeringau kedalam ransum berpengaruh nyata terhadap konsumsi ransum, Pengaruh penambahan Jeringau ke dalam ransum terhadap pertambahan berat badan dan konversi ransum berpengaruh sangat nyata. Kecendrungan lebih baik terhadap peubah yang diamati pada pemberian 1% dan Diharapkan adanya penelitian lanjutan dengan level penambahan Jeringau yang sesuai.

This replacement of natural disinfectants is expected to improve fertility, increase hatchability, increase hatching weight and reduce mortality. This study aims to determine whether the fumigation of betel leaf water can improve fertility, increase hatchability, increase hatching weight and reduce mortality in quail hatching, as well as determine the best level of administration in a mixture of betel leaf water and aquades. This study used a completely randomized design (CRD) consisting of 5 treatments, namely p1 (Control), p2 (70% Alcohol), p3 (20 ml Betel Leaf Extract + 80 ml Aquades), p4 (30 ml Betel Leaf Extract + 70 ml Aquades ), and p5 (40 ml Betel Leaf Extract + 60 ml Aquades) and 4 replicates. The data obtained were processed using variance, if the results showed significant differences, they were tested using the Duncan multiple range test (DMRT). The results showed that quail eggs fumigated using Betel Leaf Extract had an average fertility ranging from 80.00 Ã¢â‚¬â€œ 97.00%. The average hatchability ranged from 80.55Ã¢â‚¬â€œ 96.91%. The average hatching weight ranged from 8.72 to 8.74 grams. And the average mortality ranged from 3.09 to 19.45%. The results of the study on the effect of treatment on fertility, hatchability and mortality showed a very significantly different effect (P<0.01). Meanwhile, on hatching weight, the effect was not significantly different (P>0.05). Based on the results of this study, it can be concluded that the most optimal fumigation using Betel Leaf Extract is treatment 3 (20 ml Betel Leaf Extract + 80 ml Aquades) with an average fertility of 97.00%, hatchability 96.91%, hatching weight 8.72 grams, and 3.09% motility.
