Abstract

The present study was conducted to evaluate the optimum level of dietary inclusion and the form of feeding sapu-sapu fish (SSF) as a single protein source for feed components of small holder Mojosari duck farming. A total of 180 twenty four wk-old laying ducks were fed with two forms (sun-dried and ground-fresh) and three levels of SSF (10, 20 and 30%) from 24 to 32 wk of age. Experimental diets were formulated containing 105.1; 141.5 and 177.9 g/kg crude protein and 3078; 3065 and 3052 kcal metabolizable energy (ME) /kg diet. Production performance and egg quality were measured. The form of SSF had a significant effect (P<0.0001) on feed intake, egg production, feed conversion, egg mass and egg number except final body weight. No significant effects (P>0.05) were found on all of the performance parameters measured due to feeding levels of SSF except feed intake and final body weight. The interaction of form and feeding level was significant (P<0.05) on egg and body weights. Low performance and egg quality were observed in the birds fed a diet containing the dried SSF. It can be suggested that local ducks required 20% SSF as a single protein source for maximum egg production (41.2%) and total egg number per wk (3.1 eggs/bird/wk) during 8 wk of rearing period. Egg quality can be improved by feeding the fresh SSF. However, due to be sufficiently better processing technique, the dried SSF would be potential to replace the common fish for laying ducks.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh media tumbuh yang berasal dari berbagai kotoran ternak yang ditambahkan ampas tahu terhadap pertumbuhan dan produksi larva. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan 3 ulangan dan masing-masing ulangan terdiri dari 3 unit, pada setiap unit ditumbuhkan larva sebanyak 3 g (umur 3 hari). Adapun perlakuan yang diterapkan adalah sebagai berikut: perlakuan A= kotoran ayam 160g + ampas tahu 160g; perlakuan B= kotoran sapi 160g + ampas tahu 160 g; perlakuan C= kotoran kambing 160g + ampas tahu 160g. Waktu pengamatan dan pemeliharaan larva selama 18 hari. Parameter yang diamati pertumbuhan bobot badan (PBB), panjang badan, produksi, Efisiensi of Conversion Digested-Feed (ECD) dan Waste Reduction Index (WRI). Hasil penelitian menunjukkan bahwa perlakuan A menghasilkan PBB, panjang badan dan produksi larva signifikan (P&lt;0.05) lebih tinggi dibandingkan perlakuan B dan C. Perlakuan C yaitu penggunaan kotoran kambing + ampas tahu menghasilkan ECD signifikan (P&lt;0.05) lebih efisien dalam memanfaatkan pakan untuk panjang badan. Indeks pengurangan limbah (Waste Reduction Index/WRI) signifikan pada perlakuan A dan B, yang berarti perlakuan A dan B lebih efisiensi dalam mereduksi substrat yang diberikan dalam waktu tertentu. Kesimpulan dari penelitian ini bahwa penggunaan media kotoran ayam + ampas tahu menghasilkan pertumbuhan dan produksi larva yang lebih efisien.
