PENGARUH PEMBATASAN RANSUM DAN IMPLIKASINYA TERHADAP PERFORMA PUYUH PETELUR PADA FASE PRODUKSI PERTAMA [The Effect of Restricted Feeding and Its Implication on the Performance of Coturnix-coturnix japonica at the First Production Phase]

Abstract

ABSTRAK Tujuan penelitian untuk mempelajari pengaruh pembatasan pemberian ransum terhadap performa puyuh petelur (Coturnix-coturnix japonica) pada fase produksi pertama. Rancangan percobaan yang digunakan dalam penelitian adalah rancangan acak lengkap. Materi penelitian yang digunakan adalah 150 ekor puyuh petelur berumur 5 - 6 minggu (produksi 5 %), yang dibagi menjadi 5 kelompok perlakuan secara random dan 6 ulangan. Ransum yang dipakai mengandung 2900 kkal/kg energi metabolis dan 20 % protein kasar. Metode pemberian ransum yang digunakan adalah ransum dengan konsumsi ad libitum ( R1); 95 % ad libitum (R2) ; 90% ad libitum (R3); 85% ad libitum (R4); 80 % ad libitum (R5) selama 24 minggu masa produksi. Peubah performa yang diamati adalah produksi telur, konversi ransum, berat telur, dan income over feed cost. Hasil penelitian menunjukkan bahwa : pemberian ransum sampai dengan 90% ad libitum tidak mengubah performa, sedangkan pemberian ransum lebih rendah dari 90% ad libitum menyebabkan menurunnya performa. Dilihat dari segi income over feed cost, pemberian ransum 90% ad libitum yang paling menguntungkan.

One hundred and fifty of Coturnix-coturnix japonica, 5 - 6 weeks of age with the initial production of 5 %, and were evaluated in the study. A completely randomized design with 5 treatments with 6 replications were used to arrange the treatments. The diet contained 2900 kcal/kg of metabolizable energy and 20% of crude protein. The treatments of restricted feeding were ad libitum consumption ( R1); 95% ad libitum (R2); 90% ad libitum (R3); 85% ad libitum (R4); 80% ad libitum (R5). Birds were fed throughout 24 weeks of the production period. Each group of treatment was observed on egg production, feed conversion, egg weight, and income over feed cost. The results showed that the restricted feeding up to 90 % ad libitum did not affect the performance, but below 90% ad libitum of the restricted feeding decreased the productivity performance of birds. The highest income over feed cost was achieved by the restricted feeding of 90 % ad libitum. Keywords : restricted feeding, production, Coturnix-coturnix japonica
