Abstract

The quality of feed is not only determined by the nutrient content and digestibility of the feed or feed ingredients, but also determined by the palatability of the feed. Palatability is one of important factor in the preparation of rations, because palatability affects the amount of feed intake. The purpose of the study was to determine the effect of feed commercial mixed with palm kernel meal (PKM) that was hydrolyzed by sheep rumen liquor enzyme to palatability of feed by measuring total feed consumption and growth responses of seed catfish (Pangasius hypopthalmus Sauvage). The feeds used in the study were commercial feed added hydrolyzed palm kernel meal (PKMe) and unhydrolized palm kernel meal (PKM). The treatments were as follows A). Commercial feed, B). 30% + 70% BKSecommercial feed30% PKMe + 70% commercial feed, C). 40% PKMe + 60% commercial feed, D). 30% PKM + 70% commercial feed, E). 40% PKM+ 60% commercial feed. Ten fishes with wight around 20 g were used in the trial and held in 80 l tanks. A completely randomized experimental design consisted of 1 variable and triplicates were selected. The result of the experiment showed that feed consumption was not significantly different among the treatment. It was showed that the test diet have a good palatability. The result of feed consumption, survival rate and growth responses observation showed that it was not significantly different among the treatments (P>0.05). Result of digestibility analysis showed that diet A and B have digestibility coefficient higher than diet C and D. Based on the evaluation in those parameters it was concluded that palm kernel meal that has been hydrolized by sheep rumen liquor enzyme have a good palatability and can be used as feed for seed catfish (Pangasius hypophthalmus Sauvage) with addition of up to 40% in the feed.

Abstract

Pada segmen pembenihan, ikan patin Pasupati II hasil hibridisasi antara ikan patin Siam betina dan ikan patin Jambal jantan menunjukkan performa terbaik dibandingkan ikan patin Pasupati l, dan patin Siam F-1.Penelitian ini bertujuan untuk menguji performa ikan patin Pasupati II pada segmen pembesaran yang dilakukan di kolam air tenang (KAT) berukuran 50 m2, dan di jaring (berukuran 5 m x 3 m x 1,5 m) yang dipasang di tambak air payau (TAP, salinitas < 10 ppt). Ikan uji yang digunakan adalah ikan patin Pasupati II, Pasupati I, dan patin Siam F-1 dengan bobot awal di KAT 11,1-16,1 g/ekor, dan di TAP 21,3-32,5 g/ekor. Sebanyak dua KAT, dan dua jaring di TAP digunakan untuk setiap kelompok ikan. Parameter yang diamati meliputi: pertambahan bobot dan panjang harian, konversi pakan, sintasan, kualitas air pemeliharaan, dan konsentrasi hormon Insuline-like Growth Factor (IGF-I) pada plasma darah. Hasil penelitian menunjukkan bahwa performa ikan patin Siam F-1 pada parameter pertambahan bobot memberikan yang terbaik (P<0,05) dibandingkan patin Pasupati I dan II yang dipelihara di KAT dan di TAP. Kemudian performa pertambahan bobot ikan patin Pasupati II lebih baik (P<0,05) daripada patin Pasupati I yang dipelihara di TAP. Hasil analisis ELISA pada beberapa ikan uji yang dipelihara di KAT menunjukkan bahwa konsentrasi hormon IGF- 1 tertinggi terdapat pada ikan patin siam F-1 (4,48 ± 0,81 ng/mL), kemudian diikuti oleh patin Pasupati II (3,96 ± 0,51 ng/mL); dan terendah pada ikan patin Pasupati I (3,93 ± 0,54 ng/mL). Jika dicermati dari data pertumbuhan dan konsentrasi hormon IGF-1 ikan uji ternyata terdapat korelasi yang positif antara pertumbuhan ikan dengan konsentrasi hormon IGF-1, semakin tinggi tingkat pertumbuhan ikan maka semakin tinggi konsentrasi hormon IGF-1 pada ikan uji.In thenursery, Pasupati II catfish hybrid of female Siamese catfish and male Jambal catfish showed the best performance compared to Pasupati I catfish and Siam catfish F-1 generation. The aim of this study was to test performance of Pasupati II on grow out segment in freshwater pond (KAT) measure 50 m2 and in net cage (measure 3 m x 5 m x 1.5 m) which settled in brackishwater pond (TAP, salinity < 10 ppt). The fish that used were Pasupati II, Pasupati I, and Siam catfish F-1 with body weight of 11.1-16.1 g/fish in KAT, and 21.3-32.5 g/fish in TAP. A total of two KAT, and two TAP were used for each group of fish. Parameters observed were included daily body weight and length, feed conversion ratio (FCR), survival rate, water quality, and concentration of insulin-like growth factor (IGF-1) hormone on plasma. The results showed that the performance of Siamese catfish F-1 growth parameters give the best weight gain (P<0.05) than catfish Pasupati I and II were maintained at KAT and TAP. Then the weight gain performance catfish Pasupati II was better (P<0.05) than that of catfish Pasupati I reared in TAP. Results of ELISA analysis on some of the fish that are reared in the KAT were showed that the concentration of the hormone IGF-1 was highest in F-1 Siamese catfish (4.48 ± 0.81 ng/mL), followed by Pasupati catfish II (3.96 ± 0.51 ng/mL) and the lowest in the Pasupati catfish I (3.93 ± 0.54 ng/mL). When the data of growth and IGF-1 hormone concentrations in the tested fish was examined there was a positive correlation, the higher the growth rate of the fish followed the higher concentration of the IGF-1 hormone in the test fish.
