Organ Dalam dan Saluran Pencernaan Ayam IPB-D1 yang DiberiI Jus Kulit Buah Naga dan Kadar Protein Pakan Berbeda | Internal Organs and Digestive Tract of IPB-D1 Chicken Given Dragon Fruit Peel Juice and Different Protein Levels in Feed

Penelitian ini bertujuan mengevaluasi efektivitas pemberian jus kulit buah naga dan kadar protein berbeda terhadap organ dalam dan saluran pencernaan ayam IPB-D1. Penelitian ini menggunakan 200 ekor ayam IPB-D1 dengan rancangan acak lengkap faktorial (2x2). Faktor (1) air minum (jus kulit buah naga, kontrol) dan (2) pakan (rendah protein, tinggi protein). Peubah yang diamati yaitu persentase bobot organ dalam, saluran pencernaan, dan panjang relatif saluran pencernaan. Data dianalisis menggunakan software IBM SPSS versi 25 dengan analisys of variance (ANOVA) menggunakan metode Steel dan Torrie (1993). Hasil penelitian menunjukkan bahwa pemberian pakan tinggi protein berpengaruh nyata (P<0,05) terhadap peningkatan persentase bobot empedu, proventrikulus dan sekum. Jus kulit buah naga tidak berpengaruh nyata (P>0,05) terhadap persentase bobot organ dalam, bobot dan panjang relatif saluran pencernaan. Kesimpulan penelitian ini adalah pemberian jus kulit buah naga dan pakan dengan kadar protein berbeda tidak memberikan efek negatif terhadap persentase organ dalam dan saluran pencernaan ayam IPB-D1

This study aimed to evaluate the effectiveness of administering dragon fruit peel juice and different protein levels on the internal organs and digestive tract of IPB-D1 chickens. This study used 200 IPB-D1 chickens with a completely randomized factorial design (2x2). Factors were (1) drinking water (dragon fruit peel juice, control) and (2) feed (low protein, high protein). The variables observed were the percentage of internal organ weight, digestive tract, and the relative length of the digestive tract. Data were analyzed using IBM SPSS software version 25 with analysis of variance (ANOVA) using the method of Steel and Torrie (1993). The results showed that the provision of high-protein feed had a significant effect (P<0.05) on the increase in the percentage of gallbladder weight, proventriculus, and cecum. Dragon fruit peel juice had no significant effect (P>0.05) on the percentage of internal organ weight, weight, and relative length of the digestive tract. The conclusion of this study is that the provision of dragon fruit peel juice and feed with different protein levels did not have a negative effect on the percentage of internal organs and digestive tract of IPB-D1 chickens
