Abstract

Penelitian ini dilakukan untuk mengetahui taraf optimal pengaruh interval inseminasi buatan (IB) dan konsentrasi spermatozoa terhadap daya tunas serta kematian embrio ayam Sentul. Penelitian dilaksanakan menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL) faktorial pola (3x3) terdiri atas sembilan kombinasi perlakuan dan tiga ulangan. Materi penelitian yang digunakan 108 ekor ayam Sentul betina dan 24 ekor ayam Sentul jantan. Interval IB (I) sebagai faktor pertama terdiri atas i1 (setiap tiga hari), i2 (setiap enam hari), dan i3 (setiap sembilan hari). Konsentrasi spermatozoa (K) sebagai faktor kedua terdiri atas k1 (50 juta), k2 (100 juta), dan k3 (150 juta). Hasil analisis variansi menunjukkan bahwa interaksi antara interval IB dengan konsentrasi spermatozoa berpengaruh tidak nyata (P>0,05), interval IB berpengaruh sangat nyata (P<0,01), dan konsentrasi spermatozoa berpengaruh nyata (P<0,05) terhadap daya tunas ayam Sentul. Hasil uji lanjut, yaitu uji orthogonal polynomial menunjukkan titik optimal interval IB pada interval lima hari menghasilkan daya tunas 91,34% dengan persamaan kuadratik Y=62,381+11,542X–1,150X², dan titik optimal konsentrasi spermatozoa pada 109 juta menghasilkan daya tunas 90,51% dengan persamaan kuadratik Y=42,657+0,875X–0,004X². Hasil analisis variansi kematian embrio menunjukkan bahwa interval IB, konsentrasi spermatozoa, dan interaksi antara kedua faktor tersebut berpengaruh tidak nyata (P>0,05) terhadap kematian embrio ayam Sentul.

Abstract

The research materials consisted of 80 commercial laying hens maintained for 8 weeks. The hens were kept in battery cages, each containing four birds, equipped with feeders and drinkers, as well as tools for measuring egg quality. The feed used during the production period consisted of ground corn (50%), rice bran (25%), and concentrate (25%) with nutrient content of 2900 kcal/kg metabolizable energy, 17.5% crude protein, 3% calcium (Ca), and 1.6% phosphorus (P). This study employed an experimental method by measuring egg weight and yolk color with the addition of turmeric powder supplementation. The experimental design used was a Completely Randomized Design (CRD) with four treatments and five replications. The treatments were: P0 (control), P1 (1% turmeric powder), P2 (2% turmeric powder), and P3 (3% turmeric powder). The results of analysis of variance showed that the addition of turmeric powder had no significant effect (P > 0.05) on egg weight, but had a highly significant effect (P < 0.01) on yolk color. It can be concluded that supplementation of 2–3% turmeric powder improves yolk color, with the highest yolk color observed in P3 (3% turmeric powder).
