Kinerja Produksi dan Kualitas Karkas Itik yang Diberi Ransum Mengandung Ampas Sagu

Abstract

The aim of the study was to determine the effect sago waste in the rations on performance and carcass quality of duck as meat producer. The treatments of this experiment were R0 (0% sago waste/control diet), R1 (5% sago waste), R2 (10% sago waste), and R3 (15% sago waste). The experimental died contained 16% crude protein and 2900 kcal /kg metabolizable energy. Ducks used in this experiment was 6 weeks old male of ducks Mojosari and Pekin cross breed. The research design use was a complete Randomized Design using 4 feeding treatment, 5 replications, and 3 ducks per replication pens. The parameters measured were: feed intake, weight gain, feed conversion, carcass weight, carcass percentage and abdominal fat percentage. The results showed that the used of sago waste had no significant effect on feed consumption, weight gain, feed conversion, carcass weight, carcass and abdominal fat percentage. It can be concluded that used of sago waste up to 20% has no negative effects on performance and carcass quality of ducks.

 ABSTRAK
 Penelitian ini bertujuan untuk mengkaji pengaruh penggunaan ampas sagu dalam ransum terhadap kinerja produksi dan kualitas karkas itik sebagai penghasil daging. Perlakuan pakan yang dicobakan dalam penelitian ini adalah R0 (tanpa ampas sagu), R1 (ampas sagu 5%), R2 (ampas sagu 10%), dan R3 (ampas sagu 15%). Ransum disusun mengandung protein kasar 16% dan energi metabolis 2900 kkal/kg. Itik yang digunakan adalah itik jantan persilangan Mojosari dan Pekin berumur 6 minggu. Rancangan penelitian yang digunakan adalah rancangan acak lengkap pola searah dengan 4 perlakuan pakan dengan 5 ulangan, dan 3 ekor itik untuk tiap ulangan. Parameter yang diamati adalah: konsumsi ransum, pertambahan berat badan, konversi ransum, berat karkas, persentase karkas dan persentase lemak abdominal. Hasil penelitian menunjukkan bahwa penggunaan ampas sagu tidak berpengaruh signifikan terhadap konsumsi ransum, pertambahan bobot badan, konversi ransum, berat karkas, persentase karkas dan lemak abdominal. Dengan demikian dapat disimpulkan bahwa penggunaan ampas sagu sampai taraf 20% tidak berpengaruh negatif terhadap kinerja produksi dan kualitas karkas itik.
 Kata kunci: ampas sagu, itik, kualitas karkas, lemak abdominal

Performance and Carcases Percentage of Pekin Duck Supplied With Sago Pith Silage as an Energy Source

“…The growth of Pekin ducks fed with feed containing sago pith silage was not different from the control. This result was in accordance with the results reported by Hehanussa et al (2018), which found that there was no effect of giving sago pulp on MA duck crosses, and also in accordance with what was reported by Subhan et al (2009), which stated that there was no effect of giving steamed sago combined with golden snail flour on MA male ducks.…”

“…This was in line with the difference in cumulative body weight gain of experimental Peking ducks as well as ration consumption, which did not differ for each treatment. This finding is in accordance with the conclusion by Hehanussa et al (2018) that the growth rate and final weight of MA ducks treated with sago dregs did not differ due to no difference in ration consumption.…”

“…The consumption of feed for Pekin ducks fed with feed containing sago pith silage was not different from the control. This result is in accordance with the results reported by (Hehanussa et al, 2018), which found no effect of giving sago pulp on MA (crossing Mojosari-Alabio), which also confirmed the findings of Antawidjaja et al (1997), who also concluded that the provision of unfermented or fermented sago dregs (Metroxylon sago) in duck rations had no significant effect on ration consumption. However, this result is different from that reported by (Subhan et al, 2009), which states that there is a significant effect of increasing the consumption of MA male duck rations by giving steamed sago combined with gold snail flour.…”

“…These results are in agreement with Subhan et al (2009), who also found that there was no effect of steamed sago and gold snail flour on the percentage of MA duck carcasses, which ranged from 59.70 to 61.10%. Similarly, the results of Hehanussa et al (2018) found the percentage of carcasses ranged from 60.98-63.45% and tended to decrease with the addition of sago pulp in the ration, although statistically it had no significant effect. to the percentage of carcasses.…”

“…This result is in accordance with the results of Subhan et al (2009), which stated that the use of steamed sago and gold snail flour had no significant effect on feed conversion for MA male ducks, with a conversion value of between 3.45 and 3.86. Likewise, Hehanussa et al (2018) stated that the use of sago pulp in the ration had no significant effect on feed conversion for MA ducks, ranging from 4.35 to 4.96. These results illustrate that sago pith silage can be utilized to a level of 20% in pekin duck rations without affecting feed conversion.…”
