Judul: Gambaran histopatologi usus halus dan sekal tonsil pada ayam broiler yang terinfeksi marek dan pengaruh pemberian zink, bawang putih dan kunyit
Abstrak: Penelitian ini bertujuan untuk memberikan informasi dasar tentang gambaran histopatologi usus broiler setelah penambahan zink, serbuk bawang putih dan kunyit dalam ransum basal dan terjadinya infeksi virus Marek secara alami. Ayam broiler strain Ross 1 Super Jumbo 747 berumur satu hari (DOC) yang berjumlah 100 ekor dibagi dalam lima kelompok. Kelompok pertama (RO) adalah ayam yang diberi pakan basal dan dijadikan sebagai kontrol. Kelompok kedua (R1) adalah ayam yang diberi pakan basal, serbuk bawang putih 2,5% dan serbuk kunyit 1,5 %. Kelompok ketiga (R2) adalah ayam yang diberi pakan basal, serbuk bawang putih 2,5% dan ZnO 120 ppm. Kelompok keempat (R3) adalah ayam diberi pakan basal, serbuk kunyit 1,5% dan ZnO 120 ppm. Kelompok kelima (R4) adalah ayam yang diberi pakan basal, serbuk bawang putih 2,5%, serbuk kunyit 1,5% dan ZnO 120 ppm. Pada akhir penelitian ternak ayam broiler diambil satu ekor pada masing-masing unit percobaan secara acak untuk dinekropsi. Pengamatan dilakukan untuk melihat histopatologi usus halus dan sekal tonsil ayam broiler. Saat pemeliharaan ayam terinfeksi virus Marek. Secara histopatologi terjadi demielinasi pada saraf usus halus ayam, akumulasi sel tumor limfoid, proliferasi sel goblet, dan peningkatan folikel limfoid sekunder pada sekal tonsil.

Abstrak: THI WIDHYARI. The research was aimed to inform the histopathological of small intestine and cecal tonsil in Broiler that were adapted garlic powder, curcumin powder and zinc into fed basis and infection by Marek disease. This research used 100 Broilers of Ross 1 strain and start from day old chick (DOC). They were divided into 5 groups. Group R0 was treated with fed basis (as control). Group R1 was treated with fed basis, garlic powder (2,5%), and curcumin powder (1,5%). Group R2 was treated with fed basis, garlic powder (2,5%), and ZnO was 120 ppm. Group R3 was treated with fed basis, curcumin powder (1,5%), and ZnO was 120 ppm. Group R4 was treated with fed basis, garlic powder (2,5%), curcumin powder (1,5%), and ZnO was 120 ppm. At the end of the maintenance period, four chickens from each pen of five treatment groups were necroption. The observe was conducted to histopathological of small intestine and cecal tonsil of chickens. When the maintenance, chickens were naturally infected by Marek’s disease. According to histopathological, there were demyelination of small intestine nerves, accumulation of lymphoid tumor cell, proliferation of Goblet cells and increase of limfoid cells in cecal tonsil.

Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
