Fatty Acid Composition and Sensory Evaluation of The Meat of Broilers Fed Silkworm (Bombyx mori L) Pupa Dietary Supplementation
Get PDFAbstract.  The effects of silkworm pupa diets rich in n-3 fatty acids on fatty acid composition and quality of broiler meat were investigated. Diets containing varying amounts of dried or fresh pupa were prepared (1) basal contained 10 % fishmeal (control), (2) basal plus 10% of silkworm pupa-dried (SP), (3) basal plus 20% of silkworm pupa-dried (SP), (4) basal plus 5% of silkworm pupa-dried (SP) + 5% of silkworm pupa-fresh (SF), (5) basal plus 10% of silkworm pupa-dried (SP) + 10% of silkworm pupa-fresh (SF). One hundred and ninety five CPC 707 breed chickens of 21-days old were fed with the experimental diets. The prominent fatty acids in thigh meat tissue were oleic acid, palmitic acid, linoleic acid, stearic acid, and α-linolenic acid. Both the total amounts of n-3 fatty acids and polyunsaturated fatty acids increased, while the total amount of n-6 fatty acids decreased with increasing levels of silkworm meal in the feed, resulting in an increase in the n-3/n-6 ratio. There were no significant differences in the effects of the treatments on the sensory quality of cooked breast meat, with the exception of taste improvement, which significantly lower in the group that was fed a basal diet containing 5% each of dried and fresh pupa. In conclusion, application of silkworm pupa as fat source in feed could improve the taste and quality of broiler meat. Keywords: Silkworm pupa, omega-3, broiler, meat quality, fatty acid composition  Abstrak: Silkworm (Bombyx mori L.) pupa adalah by-product dari hasil industri ulat sutra yang mengandung omega-3 asam alpha linolenat (18:3-n3) tinggi, sekitar 40% dari total asam lemak. Penelitian ini bertujuan untuk menginvestigasi pengaruh pemberian silkworm pupa pada diet ayam broiler dalam komposisi asam lemak dan kualitas daging ayam. Lima jenis diet yang digunakan adalah (1) basal yang mengandung 10% tepung ikan (control), (2) basal yang mengandung 10% pupa kering (SP), (3) basal mengandung 20% pupa kering (SP), (4) basal mengandung 5% pupa kering (SP) dan 5% pupa basah (SF), dan (5) basal mengandung 10% pupa kering (SP) dan 10% pupa basah (SF). Penelitian ini menggunakan 195 ayam broiler jantan strain CPC 707 berumur 21 hari, pemberian diet dilaksanakan selama 21 hari. Hasil penelitian menunjukkan bahwa asam oleat, palmitat, linoleat, stearat dan alpha linolenat merupakan asam-asam lemak yang dominan ditemukan pada daging paha ayam. Jumlah total omega-3 maupun asam lemak tak jenuh (PUFA) meningkat, sementara jumlah omega-6 menurun dengan penambahan silkworm pupa pada diet, menyebabkan perbandingan atau ratio n-3/n-6 menjadi tinggi. Dalam hal kualitas daging dada ayam, tidak ada perbedaan yang nyata terlihat diantara kelima perlakuan diet, dengan pengecualian pada rasa daging ayam menunjukkan nilai sensory yang rendah pada perlakuan yang mengandung 5% pupa kering dan 5% pupa basah. Kesimpulan penelitian adalah silkworm pupa dapat dijadikan sebagai sumber omega-3 pada diet untuk meningkatkan kualitas dan rasa pada daging. Kata kunci: silkworm pupa, omega-3, broiler, kualitas daging, komposisi asam lemak.F Mentang et al./Animal Production 15(1):24-30, January 201

Quantifying Feeding Regimes on Weaned Sows Under Tropical Papua Pig Keeping Systems
Get PDFBody weight measurement of weaned sow using several feeding regimes was done under traditional pig keeping systems in West Papua, Indonesia. Feeding quantification using local and non-conventional feeds applied by pig farmers were rationed. Feeds used were 1, 2 and 3 kg in fresh basis. Energy contents of each ration were 34.73, 32.63 and 36.39 MJ kg DM, respectively and protein rations were of 0.62, 0.34 and 0.99 kg CP DM. Initial sow’s body weight was in the average of 87 kg. The second feeding regimes with 2 kg day-1 on offer, obtained ransom with quality of balance, energy rich and protein rich, i.e. 22.69, 21.99 and 24.92 MJ kg DM, respectively and protein in ransom of 0.35, 0.26 and 0.72 kg CP DM. Feeding regimes with 1 kg day-1 on offer, we obtain ration with quality of balance, energy rich and protein rich, i.e. 12.04, 11.34 and 12.46 MJ kg DM, respectively and protein in ransom with 0.27, 0.18 and 0.36 kg CP DM. Initial weaned body weight was 87 kg.  A simulation using one factorial of feeding regimes was established, which was drawn and simulated using Simile version 4.7 and no environmental factors were incorporated in this model simulation. The results of this study showed the increasing body weight of sows was detected by using 3 kg of feed daily in 14 days after weaning. While 2 kg feed day-1 only met the maintenance requirement. Therefore,  there were no meat or fat deposition. Feed of 1 kg per day could induce negative impact in starvation and  body weight lost. Insufficient feed intake can induce negative impact on physiological mechanism of the sows. This is at risk while weaned sow would enter mating season and gestation period. Feeding regimes with more that 3 kg and energy ration of 34.73 MJ kg DM and digestibility of 0.82 resulted in a positive effect on sow body weight gain. Animal Production 15(2):106-118, May 201
