Judul: Effect of Corticosteroid on Limfoid Organ of Broiler.
Abstrak: Kortikosteroid merupakan senyawa anti-inflamasi yang digunakan secara luas khususnya dalam dunia peternakan. Tujuan dari penelitian ini adalah mempelajari efek kortikosteroid yaitu Prednisone pada organ limfoid ayam broiler. Sebanyak 30 ekor DOC dibagi menjadi 2 kelompok. Kelompok pertama adalah kontrol dan kelompok kedua adalah perlakuan (diberikan Prednisone 3 mg/kg BB per oral). Masing-masing kelompok dibagi menjadi 5 kelompok sesuai umur perlakuan, mulai dari umur 2 minggu sampai 6 minggu. Perlakuan ini berlangsung selama 6 minggu setelah itu ayam dinekropsi. Organ limfoid yang disampling adalah bursa Fabricius, timus, dan limpa yang selanjutnya dibuat preparat histopatologi menggunakan pewarnaan Haematoxylin Eosin dan diamati. Parameter yang diamati antara lain, jumlah limfosit, jumlah folikel limfoid, tinggi dan lebar plika bursa Fabricius, jumlah limfosit dan luas organ timus, serta jumlah limfosit dan folikel limfoid pada limpa. Data dianalisis secara kuantitatif dengan uji lanjut Tstudent. Hasil dari penelitian ini adalah kortikosteroid memberikan efek imunosupresi yang ditunjukkan menurunnya jumlah limfosit dan jumlah folikel limfoid organ limpa. Jumlah limfosit Bursa Fabricius, timus, dan limpa menunjukkan hasil yang berbeda nyata (P<0.05). Jumlah folikel limfoid besar dan kecil, tinggi dan lebar plika bursa Fabricius, luas medulla timus, dan jumlah folikel limfoid limpa menunjukkan hasil berbeda nyata (P<0.05). Kortikosteroid memberikan efek yang signifikan terhadap organ limfoid ayam broiler.

Judul: Pengaruh Pemberian Ketumbar (Coriandrum sativum L) terhadap Organ Dalam Ayam Broiler
Abstrak: Herb is plant used as a medicine, seasoning, or flavoring. When consumed by livestock in a normal dosage, it can reduce stress without any negative effects. In this study, coriander, a type of herb, was given to the broilers which were reared intensively. Coriander contains flavonoid, which is antibacterial in nature, and it also has an antioxidant that can enhance the work of immune system. The objective of this experiment was to study the effect of coriander seed in the diet on the internal organs of broilers. The research was conducted in the Laboratory of Poultry Production (Cage B), Faculty of Animal Science, Bogor Agricultural University. This study used by a completely randomized design (CRD). The study involved 120 DOC with 4 dietary treatments and 3 replication (10 broilers / cage). The dietary treatments consisted of P0 (control, without corianders seeds), P1 (1% coriander seeds), P2 (2% coriander seeds) and P3 (3% coriander seeds). The data obtained were analyzed using analysis of variance, ANOVA. The treatment that indicated a significant effect on the observed variables would be further tested by using Duncan. The research results show that the treatment of giving coriander seeds were not significant different (P> 0.05) compared to the control on gizzard, duodenum, jejenum, illeum, pancreas, seka, liver, heart and spleen. The coriander seeds treatment was significantly different (P <0.05) compared to the control on the bursa fabrisius and highly significantly different (P <0.01) on thymus weight. Coriander seeds treatment up to the level of 3% had no effects on the gizzard, duodenum, jejenum, illeum, pancreas, seka, liver, heart, kidneys, and spleen of broilers aged 5 weeks. The coriander seeds treatment up to the level of 2% increased the weight of bursa fabrisius and coriander seeds treatment up to the level of 3% increased the weight thymus.

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.
