Penambahan Calphyto (Calcium phytobiotics) sebagai Feed Additive Secara In Vivo terhadap Bobot Relatif Organ Dalam Anas javanica Fase Layer

Abstract

Abstract Research on the addition of calphyto (calcium phytobiotics) as feed additives was carried out in vivo on 120 mojosari laying ducks when entering the age of 24 weeks (layer phase). Ducks are divided into 24 flocks, each flock consists of 5 ducks. Statistical data analysis in this study used Variation Analysis (ANOVA) then continued Duncan's Multiple Distance Test (UJBD) if the research data showed significant differences between treatments. Through the Complete Randomized Design (RAL) pattern, there are 6 treatments and 4 tests where there are differences in treatment in each feed given, consisting of P0 = basal feed, P1 = basal feed + 0.25% zinc bacitracin, P2 = basal feed + 0.25% calphyto, P3 = basal feed + 0.50% calphyto, P4 = basal feed + 0.75% calphyto, and P5 = basal feed + 1% calphyto. The variables measured are the relative weight percentage of organs in mojosari laying ducks including the percentage of gizzard, heart, liver, lymph, and pancreatic weights. The final results of the study found that the addition of calphyto as a feed additive showed influence on the variable percentage of the relative weight of the gizzard (P>0.05) of the laying ducks of the mojosari layer phase by P0 = 2.04±0.17a; P1 = 2.67±0.43b; P2 = 2.03±0.16 b, P3 = 2.38±0.49 b; P4 = 2.38±0.14 b; P5 = 2.12±0.10 b. However, the variable percentage of heart, liver, lymph, and pancreas weights did not show any noticeable influence (P<0.05).Keywords: calcium, phytobiotics, mojosari laying ducks, relative weight of internal organsAbstrak Penelitian mengenai penambahan calphyto (calcium phytobiotics) sebagai feed additive dilakukan secara in vivo pada 120 ekor itik petelur mojosari saat memasuki umur 24 minggu (fase layer). Itik terbagi kedalam 24 flock, masing-masing flock terdiri dari 5 ekor itik. Analisis data secara statistik pada penelitian ini menggunakan Analisis Variasi (ANOVA) kemudian dilanjutkan Uji Jarak Berganda Duncan’s (UJBD) apabila data hasil penenilitian menunjukkan perbedaan secara signifikan antar perlakuan. Melalui pola Rancangan Acak Lengkap (RAL) terdapat 6 perlakuan dan 4 ulangan dimana terdapat perbedaan perlakuan pada setiap pakan yang diberikan, terdiri dari P0 = pakan basal, P1 = pakan basal + 0,25% zinc bacitracin, P2 = pakan basal + 0,25% calphyto, P3 = pakan basal + 0,50% calphyto, P4 = pakan basal + 0,75% calphyto, dan P5 = pakan basal + 1% calphyto. Variabel yang diukur ialah presentase bobot relative organ dalam itik petelur mojosari meliputi presentase bobot gizzard, jantung, hati, limpa, dan pankreas. Hasil akhir penelitian didapatkan bahwa penambahan calphyto sebagai feed additive menunjukkan ada pengaruh nyata pada variabel presentase bobot relatif gizzard (P>0,05) itik petelur mojosari fase layer sebesar P0 = 2,04±0,17a; P1 = 2,67±0,43b; P2 = 2,03±0,16 b, P3 = 2,38±0,49 b; P4 = 2,38±0,14 b; P5 = 2,12±0,10 b. Namun pada variabel presentase bobot  jantung, hati, limpa, dan pancreas tidak menunjukkan adanya pengaruh nyata (P<0,05).Kata kunci: kalsium, fitobiotik, itik petelur mojosari, bobot relative organ dalam
