Penelitian ini bertujuan untuk mengetahui pengaruh dari konsentrat yang berbeda dengan sumber beberapa jenis leguminosa terhadap konsentrasi NH3, dan protein total rumen secara in vitro. Materi penelitian berupa konsentrat (kandungan PK 13%, TDN 65%). Rancangan percobaan yang digunakan adalah rancangan acak lengkap dengan 7 perlakuan dan 3 ulangan. Perlakuan konsentrat adalah T1 (6% Crotalaria usaramoensi), T2 (6% Crotalaria juncea),T3 (6% Tephrosia), T4 (3% Crotalaria usaramoensi + 3% Crotalaria juncea), T5 (3% Crotalaria usaramoensi + 3% Tephrosia), T6 (3% Crotalaria juncea + 3% Tephrosia), T7 (2% Crotalaria usaramoensi + 2% Crotalaria juncea + 2% Tephrosia). Parameter yang diamati adalah produksi NH3 dan produksi protein total. Data yang diperoleh dianalisis dengan analisis ragam dan apabila terdapat pengaruh nyata (P<0,05) akibat perlakuan, dilanjutkan dengan uji wilayah ganda Duncan untuk mengetahui perbedaan antar perlakuan. Hasil penelitian menunjukkan bahwa konsentrat yang ditambah dengan berbagai jenis leguminosa mampu meningkatkan produksi amonia dan protein total. Konsentrat dengan suplemen leguminosa jenis Crotalaria mampu meningkatkan produksi NH3 dan produksi protein total. Sedangkan konsentrat dengan suplemen leguminosa jenis Tephrosia di atas 3% akan menurunkan produksi NH3 dan protein total.
ABSTRAK. Limbah daun bawang merah merupakan salah satu limbah pertanian yang sering terbuang secara percuma. Kandungan limbah daun bawang merah berupa senyawa allicin yang mampu memengaruhi profil lemak darah. Penelitian ini bertujuan untuk mengetahui pengaruh dari pemberian limbah daun bawang merah terhadap profil lemak darah domba. Penelitian dilaksanakan pada bulan Juli -September 2020 di Desa Kadirejo Kecamatan Pabelan Kabupaten Semarang. Penelitian ini menggunakan 15 ekor domba yang terbagi dalam 5 perlakuan dengan masing-masing 3 ulangan. Perlakuan yang digunakan adalah penambahan limbah daun bawang merah sebesar 0%, 10%, 20%, 30% dan 40%. Parameter profil darah yang diukur adalah HDL, LDL, trigliserida dan Kolesterol. Hasil penelitian ini menunjukkan bahwa penambahan limbah DBM 40% dalam pakan domba berpengaruh nyata (P < 0,05) terhadap peningkatan kandungan HDL dan penurunan kandungan Trigliserida, tetapi tidak berpengaruh terhadap penurunan kandungan LDL dan Kolesterol. Limbah daun bawang merah dapat digunakan sebagai hijauan alternatif pakan domba yang mampu memperbaiki profil lipid darah domba. Kata kunci: Profil darah, domba, limbah daun bawang merah, allicin ABSTRACT. Allium ascalonicum leaf is one of the agricultural wastes that is often wasted for nothing. The content of Allium ascalonicum leaves is in the form of allicin compounds which can affect the blood fat profile. This study aims to determine the effect of Allium ascalonicum leaf on the blood fat profile of sheep. This study was conducted in July -September 2020 in Kadirejo Village, Pabelan District, Semarang Regency. This study used 15 sheep divided into 5 treatments with 3 replications each. The treatment used was the addition of Allium ascalonicum leaf by 0%, 10%, 20%, 30% and 40%. Blood profile parameters measured were HDL, LDL, triglycerides and cholesterol. The results of this study indicated that the addition of 40% Allium ascalonicum leaf in sheep feed had a significant effect (P <0.05) on the increase in HDL content and decreased Triglyceride content, but did not affect the decrease in LDL and cholesterol content. Allium ascalonicum leaf can be used as an alternative forage for sheep feed which can improve the blood lipid profile of sheep.
The livestock sector is expected to make a real contribution to the development of the nation's economy. Livestock development is also directed at increasing the quality of production, increasing income, expanding employment opportunities and providing business opportunities for people in rural areas. Layer are one of the poultry commodities that have an important role as egg producers to support the availability of cheap and easy to obtain animal protein. The population of layer in Pati Regency in 2018 was 265,020 birds (BPS, 2020). Layer are increasingly in demand in the village of Tegalharjo as a profitable poultry business opportunity. Many breeders choose the business of layer as a side business or as their main income. The objectives of this study are 1). To determine the business income of layer, 2) To determine the business feasibility of layer, 3) To determine the effect of pullets, feed costs, medicines and labor on the income of layer. The research material was in the form of layer in Tegalharjo Village, Trangkil District, Pati Regency. Data collection for 3 months (March - May). The results of the research on layer in the village of Tegalharjo are feasible to work with an income of IDR 11,784,946.17 / ST / period and simultaneously there is an effect of the cost of pullets (X1), feed (X2), medicines (X3) and labor ( X4) to income.
ABSTRAK.Penelitian ini bertujuan untuk mengetahui pengaruh suplementasi daun bawang merah terhadap performan domba. Metode penelitian berupa Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 3 kali ulangan. Jumlah domba yang digunakan 15 ekor yang dibagi menjadi lima perlakuan dengan T0 (tanpa daun bawang merah); T1 (Pakan basal + 300 g daun bawang merah); T2 (Pakan basal + 600 g daun bawang merah); T3 (Pakan basal + 900 g daun bawang merah); T4 (Pakan basal + 1200 g daun bawang merah). Parameter berupa pertambahan bobot badan, konsumsi pakan, dan rasio konversi pakan. Hasil penelitian menunjukkan bahwa suplementasi daun bawang merah (Allium ascalonicum) T4 berpengaruh nyata (P<0,05) terhadap peningkatan bobot badan, konsumsi pakan, dan rasio konversi pakan. Berdasarkan penelitian ini, dapat disimpulkan bahwa suplementasi daun bawang merah sebesar 1200 g dalam ransum basal mampu meningkatkan performa domba.Kata kunci: Konsumsi pakan, konversi pakan, daun bawang merah, domba, dan pertambahan bobot badan ABSTRACT. This study aims to determine the effect of shallot leaf supplementation to lamb performance. This study method used a Completely Randomized Design (CRD) with 5 preparations and 3 replications. This study used 15 lamb's which were divided into five treatments with T0 (without shallot leaf); T1 (Basal feed + 300 g of shallot leaf as feed); T2 (Basal feed + 600 g of shallot leaf as feed); T3 (Basal feed + 900 g of shallot leaf as feed); T4 (Basal feed + 1200 g shallot leaf as feed). Parameters observed were liveweight gain, feed consumption, and feed conversion ratio ratio. The results showed that the addition of shallot leaf (Allium ascalonicum) T4 had a significant effect (P<0.05) on the increase in liveweight gain, feed consumption, and feed conversion ratio. The shallot leaf supplementation of 1200 g as feed gave better lamb performance. This study concluded that the supplementation of 1200 g of shallot leaf in the basal ration was able to provide better lamb performance.
