Judul: Substitusi Tepung Ikan dengan Bungkil Kedelai Dalam Ransum Yang Mengandung Ampas teh (Camelia sinensis) Terhadap Performan Domba Lokal Jantan
Abstrak: The subtitution of soybean meal with fish meal is used to maximaze and increase the utilization of 70% tea waste, because soybean meal with fish meal contain the most balanced amino acid comparing with others feed component. The Experiment conducted in Small Ruminant Laboratory, Department of Animal Production Science, Faculty on Animal Science, Bogor Agricultural University, from November 2003 until January 2004. 20 Local Lamb with average body weight 20.87±1.8 kg were observed. The experiment design used Completely Randomized Design with five treatments and four replications. The treatments that were given are R1 (10% soybean meal, 0% fish meal), R2 (7.5% soybean meal, 2.5% fish meal), R3 (5% soybean meal, 5% fish meal), R4 (2.5% soybean meal, 7.5% fish meal), R5 (0% soybean meal, 10% fish meal). Data were analysed with ANOVA and followed by doubel Duncan (Steel and Torrie, 1993). The result of this research showed that treatments was not a significantly different affected on feed consumption based on dry matter, average weight gain, feed conversion and Income Over Feed Cost. The average of feed consumption based on dry matter was 978.42±16.52; 999.84±25.00; 1013.21±10.39; 1013.07±15.84; 1010.25±18.47 gram/ekor/hari, average weight gain was 81.35±27.01; 87.30±29.67; 99.21±27.87; 117.06±11.90; 97.22±20.87 gram/ekor/hari, average of feed conversion was 12.97±3.91; 12.89±5.74; 10.85±3.15; 8.71±0.87; 10.74±2.19 gram/ekor/hari. It is concluded that all treatments shown a good substitution 2.5% of soybean meal with 7.5% fish meal is tend to the best of all treatment, because have good feed consumption, average weight gain, feed conversion and Income O ver Feed Cost.

Judul: Evaluation of Fish Meal and Soybean Meal Substitution in Ration for Local Sheep on Performance of Lactating Ewe and Pre-weaning Lamb
Abstrak: Aim of this study was to evaluate the effect of substitution with fish meal and soy bean meal on performance of lactating ewe and pre-weaning lamb. This study used complete randomized block design, with 3 treatments and 5 replications. 15 local sheep with gestation period of 133±8,29 day and average of body weight in the beginning was 25,13±2,90 kg. Treatments consisted of P1 : field grass + 100% commercial concentrate, P2 : field grass + 90% commercial concentrate + 10% fish meal, and P3 : field grass + 85% commercial concentrate + 15% soybean meal. Data were analyzed using ANOVA with parameters: feed consumption, nutrient ration intake, water consumption, decreased weight of pre-weaning sheep, weight of weaning sheep, birth weight of lamb, body weight of pre-weaning lamb, average body weight gain of pre-weaning lamb, estimated milk production, and feed efficiency. In addition this experiment was using descriptive analysis for a number of parameters such as income over feed cost and pre-weaning mortality. The results showed that the treatments did not significantly affect feed consumption, nutrient ration intake, water consumption, decreased weight of pre-weaning ewes, weight of weaning ewes, birth weight of lamb, body weight of pre-weaning lamb, average body weight gain of pre-weaning lamb, estimated milk production of ewes and feed efficiency and the performance of ewes fed ration with protein sources from soy bean meal was better than other treatments. It was of concluded that the subtitution of protein source did not affect significant toward production and performance of lactating both of lactating ewes and pre-weaning lamb. Feeding soybean meal fed to produce better performance.
