Penelitian “Pengaruh galur ayam lokal dan feed additive terhadap kadar total protein plasama dan fibriogen” telah dilaksanakan pada 13 Juli 2021 – 13 Oktober 2021, bertempat di Experimental farm, Fakultas Peternakan, Universitas Jenderal Soedirman, Purwokerto dan analisis darah di Laboratorium Patologi Klinik, Fakultas Kedokteran Hewan, Universitas Gajah Mada, Yogyakarta. Penelitian bertujuan untuk mengetahui pengaruh interaksi galur ayam lokal dan feed additive terhadap kadar TPP dan fibrinogen. Rancangan penelitian yang digunakan adalah RAL (Rancangan Acak Lengkap) pola faktorial terdapat 2 faktor terdiri dari faktor A (galur ayam) dan faktor B (immunomodulator feed), faktor A terdapat 3 jenis galur ayam lokal dan faktor B terdapat 4 feed yang berbeda, sehingga perlakuan yang diujicobakan 3 x 4 = 12 perlakuan dan terdapat 4 kali ulangan. Materi penelitian menggunakan 3 jenis galur ayam lokal antara lain A1 (Ayam Kampung), A2 (Ayam KUB) dan A3 (Ayam Kedu) yang sudah dipelihara sebelumnya dari DOC masing-masing sebanyak 160 ekor sehingga total 480 ekor, pakan ayam periode awal sampai dengan pertumbuhan (complete feed), pakan basal, feed additive sebagai immunomodulator, dan bahan kimia untuk analisa darah. Pakan yang digunakan adalah pakan basal dengan penambahan beberapa jenis feed additive terdiri dari B1 (pakan basal/kontrol), B2 (penambahan 1% tepung sambiloto), B3 (penambahan 1% tepung bawang putih), dan B4 (penambahan 1% tepung Kalimun®). Perlakuan yang diberikan adalah A1B1, A1B2, A1B3, A1B4, A2B1, A2B2, A2B3, A2B4, A3B1, A3B2, A3B3, A3B4. Peubah yang diukur meliputi kadar TPP dan Fibrinogen. Analisis data menggunakan analisis variansi (ANAVA). Hasil rataan kadar total protein plasma yaitu 2,4 ± 0,3 g/dL sampai dengan 2,8 ± 0,4 g/dL. Hasil rataan kadar fibrinogen sebesar 0,1 ± 0,1 - 0,3 ± 0,1 g/dL. Hasil analisis variansi (ANAVA) menunjukkan bahwa interaksi antara galur ayam lokal dan suplementasi feed additive maupun masing-masing faktor berpengaruh tidak nyata (F hitung < F tabel 0,05) terhadap kadar total protein plasma dan fibrinogen (P>0,05). Penelitian ini dapat disimpulkan bahwa galur ayam kampung, KUB, dan Kedu memiliki kadar TPP dan fibrinogen yang relatif sama. Supementasi feed additive tidak mengganggu status fisiologi ayam berdasarkan kadar fibrinogen dan TPP. Ayam Kedu dengan kombinasi perlakuan pakan basal dengan penambahan feed additive Kalimun® (1%) cenderung memiliki rataan kadar TPP dan fibrinogen lebih tinggi dibandingkan kontrol dan perlakuan lainnya.

The research "The effect of local chicken strains and feed additive on total plasma protein and fibrinogen levels" was carried out on July 13, 2021 - October 13, 2021, at the Experimental farm, Faculty of Animal Husbandry, Jenderal Soedirman University, Purwokerto and blood analysis at the Pathology Laboratory Clinical, Faculty of Veterinary Medicine, Gajah Mada University, Yogyakarta. The aim of the study was to determine the effect of the interaction of local chicken strains and feed additives on the levels of TPP and fibrinogen. The research design used was RAL (Completely Randomized Design) factorial pattern there were 2 factors consisting of factor A (chicken strain) and factor B (immunomodulator feed), factor A there were 3 types of local chickens and factor B there were 4 feeds, so that the treatment tested was 3 x 4 = 12 treatments and there were 4 replications. The research material used 3 types of local chickens, including A1 (Village Chicken), A2 (KUB Chicken) and A3 (Kedu Chicken) which had been previously reared from DOC, each of which was 160 so that a total of 480 tails, chicken feed for the early period up to growth (complete feed), basal feed, feed additive as an immunomodulator, and chemicals for blood analysis. The feed used was basal feed with the addition of several types of feeds additive consist of B1 (basal/control feed), B2 (addition of 1% Sambiloto flour), B3 (addition of 1% garlic flour), and B4 (addition of 1% Kalimun® flour). The treatments given were A1B1, A1B2, A1B3, A1B4, A2B1, A2B2, A2B3, A2B4, A3B1, A3B2, A3B3, A3B4. The variables measured included levels of TPP and Fibrinogen. Data analysis used analysis of variance (ANOVA). The average total plasma protein levels were 2.4 ± 0.3 g/dL to 2.8 ± 0.4 g/dL. The results of the average fibrinogen levels were 0.1 ± 0.1 - 0.3 ± 0.1 g/dL. The results of analysis of variance (ANOVA) showed that the interaction between local chicken strains and feed additive as well as each factor had no significant effect (F count < F tabel 0.05) on total plasma protein and fibrinogen levels (P> 0.05). It can be concluded that the free-range chicken, KUB, and Kedu strains had relatifly the same levels of TPP and fibrinogen. Supplementation of  feed additives did not interfere with the physiological status of chickens based on fibrinogen and TPP levels. Kedu chickens with a combination of basal feed treatment with the addition of Kalimun® feed additive (1%) had higher TPP and fibrinogen levels than the control and other treatments.
