Judul: The Effect of Vitamin E and Selenium Supplementation towards the Internal Organ Characteristics of IPB-D2 Chickens during Developer-Layer Period
Abstrak: Penelitian ini bertujuan mengevaluasi pengaruh suplementasi vitamin E dan mineral Se dengan komposisi kebutuhan nutrien yang berbeda terhadap kualitas organ dalam Ayam IPB-D2. Rancangan percobaan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) Faktorial 2 x 2 (faktor A untuk jenis rasum dan faktor B untuk suplementasi vitamin E sebanyak 100 ppm dan jumLah mineral Se 1 ppm, masing-masing perlakuan diulang sebanyak lima kali. Peubah yang diamati yaitu bobot potong unggas, bobot dan persentase organ dalam ayam IPB-D2 (hati, jantung, empedu, limfa, ginjal, rampela, thimus, bursa, pankreas, dan proventikulus). Data diolah menggunakan uji ANOVA. Hasil penelitian menunjukkan tidak terdapat interaksi antara pemberian jenis ransum berbeda dan suplementasi vitamin E dan mineral Se terhadap persentase bobot organ dalam. Jenis ransum berpengaruh sangat nyata pada kenaikan persentase bobot empedu (P<0,01), namun pemberian suplementasi vitamin E dan Se tidak berpengaruh nyata pada kenaikan bobot organ tersebut. Sedangkan jenis ransum serta suplementasi vitamin E dan Se berpengaruh nyata pada persentase bobot proventikulus (P<0,05)., This study aimed to evaluate the effect of vitamin E and mineral Se supplementation with different compositions of nutrient requirements on the internal organ quality of IPB - D2 Chickens. The experimental design used in this study was a 2 x 2 factorial completely randomized design (CRD) (factor A for the type of ransum and factor B for vitamin E supplementation of 100 ppm and the amount of mineral Se 1 ppm. Each treatment was repeated as much as five times. The variables observed were slaughter weight of poultry, weight and percentage of internal organs of IPB-D2 chickens (liver, heart, bile, spleen, kidney, rampella, thymus, bursa, pancreas, and proventiculus). The data is processed using the ANOVA test. The results showed there was no interaction between giving different types of rations and vitamin E and mineral Se supplementation on the percentage of internal organ weights. Type of rations had a very significant effect on increasing bile weight (P<0.01), but vitamin E and Se supplementation did not significantly affect the increase in the percentage weight of the organ. While the type of ration and vitamin E and Se supplementation are significantly affected proventiculus percentage weight (P<0.05).

Judul: Vitamin E Supplementation in Diets on The Percentage of Carcasses and Non Carcasses, and Meat Bone Ratio in IPB-D3
Abstrak: Tujuan penelitian ini adalah untuk mengevaluasi suplementasi vitamin E dalam ransum terhadap persentase karkas, non karkas, serta rasio daging tulang ayam IPB-D3 dalam ransum yang berbeda. Penelitian ini menggunakan 160 ekor ayam IPB-D3 yang diberi ransum perlakuan dari umur 5 sampai 12 minggu. Penelitian ini menggunakan rancangan acak lengkap (RAL) pola faktorial dengan dua faktor yaitu jenis ransum (SNI dan SNI+10%) dan suplementasi vitamin E (0 ppm dan 200 ppm). Perlakuan ransum yang diberikan adalah sebanyak 4, yaitu (P1) ransum SNI, (P2) ransum SNI+10%, (P3) ransum SNI+vitamin E 200 ppm, dan (P4) ransum SNI+10%+vitamin E 200ppm. Hasil penelitian menunjukkan bahwa jenis ransum SNI+10% meningkatkan persentase bobot karkas, tetapi menurunkan panjang relatif bobot duodenum, persentase jejunum, panjang relatif jejunum, panjang relatif ileum, dan persentase sekum. Kesimpulan penelitian ini adalah jenis ransum dengan kandungan 10% lebih besar dari SNI ayam kampung mampu meningkatkan bobot karkas ayam IPB-D3., The purpose of this study was to evaluate vitamin E supplementation in the diet to the percentage of carcass, non carcass, and meat bone ratio of IPB-D3 chicken in different diets. This study used 160 IPB-D3 chickens that were given treatment diets from 5 to 12 weeks of age. This study used a factorial RAL pattern with two factors, namely the type of diet (SNI and SNI + 10%) and vitamin E supplementation (0 ppm and 200 ppm). The diets treatments given were 4, namely (P1) diet SNI, (P2) diet SNI+10%, (P3) diet SNI+vitamin E 200 ppm, and (P4) diet SNI+10%+vitamin E 200ppm. The results of the analysis showed that the type of diet SNI+10% increased the percentage of carcass weight, but decreased the relative length of the duodenum, the percentage of the jejunum, the relative length of the jejunum, the relative length of the ileum, and the percentage of the cecum. The type of SNI diet for native chickens with nutrients above 10% was able to increase the carcass weight of IPB-D3 chickens. The type of SNI diets for native chickens with nutrients above 10% was able to increase the carcass weight of IPB-D3 chickens.
