Growth Response And Production Efficiency Of Broiler Chicks Treated By Different Zeolite Spreading Frequency On Litter Base

The objective of this research was to study the growth and efficiency of broiler productivity. The research was conducted through the application of zeolite spreading treatment into the broiler housing in Non-ruminant Research Station of Animal Science Laboratory of Papua State University. Study was arranged by Randomized Sample Design with four treatments: P0 (control; without zeolite spreading); P1 (once time spreading during the research period); P3 (three times application of spreading during the research period); and P5 (five times of spreading or once a week during the research period). The application of zeolite spreading was not significantly influenced the rate growth of broiler, though there is a tendency increasing weight gain along with the increased in zeolite spreading level on the litter base. P3 (three times of zeolite spreading during research) produce the feed efficiency of 0.53. Economically, Income Over Feed Chick and Zeolite Cost (IOFCZC) per head per housing unit with the application of zeolite spreading more demand compared to housing units without spreading treatment

Kualitas Nutrisi Dendeng dan Abon Rusa dengan Penambahan Antioksidan Minyak Buah Merah (Pandanus conoideus L) dan Ekstrak Rumput Kebar (Biophytum Petersianum)

Penelitian ini bertujuan meningkatkan kualitas nutrisi dendeng dan abon daging rusa dengan memodifikasi proses pembuatannya melalui penambahan minyak buah merah (Pandanus conoideus L) dan ekstrak rumput kebar (Biophytum petersianum) sebagai sumber antioksidan alami. Hasil penelitian memperlihatkan bahwa nilai nutrisi produk olahan daging tidak saja dipengaruhi oleh adanya penambahan senyawa antioksidan, tetapi jenis produk olahan yang dihasilkan. Pemberian suplementasi bahan sumber antioksidan meningkatkan daya awet pada dendeng sayat dan abon yang diperlihatkan oleh penurunan nilai aktivitas air (Aw) dan nilai thiobarburic acid (TBA). Nilai Aw pada dendeng sayat menurun dari 0,694 menjadi 0,691, dan nilai TBA-nya menurun dari 0,128 menjadi 0,120 mg/kg. Pada abon nilai Aw menurun dari 0,756 menjadi 0,701, dan nilai TBA-nya menurun dari 0,139 menjadi 0,055 mg/kg. Peningkatan nilai nutrisi terdapat pada produk abon, terjadi pada nilai protein meningkat dari 33,20 menjadi 35,60%. Meskipun untuk kadar lemak terjadi peningkatan pada semua jenis produk olahan yang diberi penambahan senyawa antioksidan, tetapi tidak demikian pada kandungan asam-asam lemak produk. Pemakaian minyak buah merah dan ekstrak rumput kebar umumnya menurunkan kandungan asam-asam lemak produk olahan daging rusa, kecuali komponen asam lemak linolenat

Nutritive Value and the Quality of Ensiled Napier Grass (Pennisetum Purpureum Schum.) and Banana (Musa Acuminata) Peelings

This paper aimed to evaluate the nutritive value and the quality of ensiled Napier grass (Pennisetum purpureum Schum) and banana (Musa acuminate) peelings. Different levels of banana peeling and Napier grass were used in this study. The levels of Napier grass and banana peeling compared as treatments with four replications were as follows: 100% Napier Grass (NG), 75% (NG) + 25% Banana Peeling (BP), 50%NG + 50%BP, 25%NG + 75% BP and 100%BP. Napier grass and banana peeling were mixed based on the percentage combination as treatments, weighed and placed into empty jam bottle with weights ranging from 64.4 grams to 509.2 grams as a simulated laboratory silo. Samples were stored in eight weeks at the Dairy Training Research Institute. Proximate analyses were done at Animal Nutrition Laboratory Institute of Animal Science while ADF, NDF, IVDMD, and IVOMD were done at the Animal Nutrition Division Laboratory at Dairy Training and Research Institute, UP Los Baños. Physically, the color of silage were light yellow with a little greenish color for 100% napier grass, light to moderately yellow for the three combinations of napier and banana peel and yellow for 100% banana peel. Texture ranged from dry and coarse for napier grass, relatively dry for the combinations and moderately wet for the banana peel. The napier grass had a slightly acidic smell, the combinations had slightly sweet, acidic smell while the 100% banana peel had a sweeter, acidic smell. Likewise, pH before ensiling had ranged from 5.7 (25%NG + 75%BP) to 7.5 ( 100% BP) while after ensiling the pH changed from 4.575 ( 100% napier grass) to 5.75 ( 100% banana peel ). There were significant differences on DM, Moisture, CP, EE, CF, and Ash before ensiling. Similar trend was observed after ensiling except the ash content of all the treatments. ADF and NDF did not show significant variations in all treatments. IVDMD and IVOMD before ensiling varied significantly, but after ensiling only IVDMD of the treatments differed significantly. In terms of physical attributes, nutritive value and digestibility, banana peel can be used as silage material. All treatments generated comparable acceptability when fed to the animal. It is suggested that further study, specifically in vivo trial, will be conducted to validate the feeding and nutritional value of banana peel as alternative silage for ruminants
