Persentase Non Karkas dan Organ Imunitas Ayam IPB-D1 Jantan dan Betina pada Pemeliharaan Sistem Free-Range

Abstract

Ada dua produk yang dihasilkan pada saat pemotongan, yaitu karkas sebagai hasil utama dan non-karkas sebagai hasil samping. Organ limfoid merupakan organ yang berperan dalam sistem kekebalan tubuh unggas. Penelitian ini bertujuan untuk menganalisis persentase bobot organ non-karkas dan organ imunitas, serta menganalisis hasil pengukuran usus pada ayam IPB-D1 jantan dan betina yang dipelihara secara free-range. Penelitian ini menggunakan ayam IPB-D1 jantan dan betina masing-masing 15 ekor. Data dianalisis dengan menggunakan uji T-independent. Hasil penelitian ini menunjukkan bahwa persentase limpa dan tembolok sangat berbeda nyata; persentase duodenum berbeda nyata; dan tidak berbeda nyata pada persentase darah, bulu, kepala, leher, cakar, jantung, hati, timus, bursa fabricius, jejenum, ileum, sekum, dan kolon. Jenis kelamin pada ayam IPB-D1 tidak berpengaruh pada persentase non-karkas dan organ imunitas ayam. Sistem free-range memiliki dampak yang positif yaitu sesuai dengan animal welfare, dan hal negatif yaitu lebih rentan terhadap penyakit.

There are two products produced during slaughter, namely carcass as the main product and non-carcass as a side product. Lymphoid organs are organs that play a role in the immune system of poultry. This study aims to analyze the weight percentage of non-carcass organs and immune organs, as well as to analyze the results of gut measurements in male and female IPB-D1 chickens reared in a free-range system. This study used 15 male and female IPB-D1 chickens each. Data were analyzed using the independent T-test. The results of this study indicated that the percentages of spleen and cache were significantly different; duodenal percentage significantly different; and not significantly different in the percentage of blood, feathers, head, neck, claws, heart, liver, thymus, bursa of Fabricius, jejunum, ileum, cecum, and colon. The sex of the IPB-D1 chickens had no effect on the percentage of non-carcasses and immune organs of the chickens. The free-range system has a positive impact, which is in accordance with animal welfare, and the negative impact is more susceptible to disease.
