Phenotypic characteristics of Exotic-broiler, Kampung, Male Exotic-layer, KUB-1 and Pelung chickens
Full text linkThe needs for chicken meat have been dominated by meat from exotic broilers (bred from imported parent). The potential of local broilers chicken in Indonesia is expected to be able to provide the meat for national needs for chicken meat. The objective of this research was to determine the day-old-chick (DOC) phenotypic characteristics of chickens in Indonesia that have the potential as broilers. The phenotypic characteristics are in the form of body morphometry, visceral organ weight and small intestinal histo-morphology. The chickens used were the DOC type of exotic Broiler, Kampung, exotic male Layer, KUB-1 and Pelung. A total of 125 chickens consisting of 25 chickens of each strain at posthatched age were observed for its body morphometry and its visceral organ weight, and small intestinal histo-morphology. The observed data were then analyzed by similarity analysis using MVSP 3.22 to create a dendogram with the Unweighted Pair Group with Aritmetic Average (UPGMA) method. Results showed that there were 2 different clusters from the level of similarity in their characteristics. Exotic broilers had 94.65% similarity to male exotic layer chicken and 92.26% to pelung chicken, while Kampung chickens had 90.16% similarity to KUB-1Chicken. In conclusion, it is indicated that the level of similarity of the phenotypic characteristics of pelung chickens were close to the type of exotic broiler and male exotic layer chicken. This level of similarity lead to the expectation that pelung chickens potential to be a candidate for meat-type of local chicken

Genotyping in the Insulin-like Growth Factor 1 (IGF1/SnaBI) gene of Pasundan cattle with PCR-RFLP method
Full text linkGen Insulin-like Growth Factor 1 (IGF1) pada mamalia berfungsi untuk mengontrol pertumbuhan tulang dan otot. Oleh karena itu gen IGF1 banyak digunakan sebagai salah satu kandidat gen untuk seleksi ternak. Penelitian ini bertujuan untuk mengidentifikasi genotip gen IGF1 (ekson 1) menggunakan metode PCR-RFLP dengan enzim restriksi SnaBI (TAC*GTA). Sebanyak 90 ekor sampel DNA sapi Pasundan dari Kabupaten Ciamis dan Pangandaran, Jawa Barat telah digunakan pada penelitian ini. Hasil penelitian ini menunjukkan bahwa seluruh sampel yang dianalisis memiliki genotip CC dengan alel C sebagai alel yang umum pada gen IGF1/SnaBI. Genotip CC yang diperoleh pada penelitan ini disebabkan karena terdapat mutasi transisi pada posisi basa ke g.218T/C (GenBank: KF202095). Mutasi ini menyebabkan perubahan asam amino dari methionine (AUG) menjadi valine (GUG). Disimpulkan bahwa gen IGF1/SnaBI pada sapi Pasundan bersifat monomorfis dan tidak dapat digunakan untuk seleksi molekuler

Full text linkBlack Soldier Fly are natural antibiotics. It is expected that the use of BSF larvae in poultry rations as an alternative source of conventional protein will contribute to improving the immune status and maintaining animal health, thereby reducing the use of antibiotic growth promoters (AGPs). This study aimed to evaluate the effect of the best type of BSF protein for determining the health status of laying hens based on the activity and capacity of macrophage phagocytosis on the non-protein A bacterium Staphyllococcus aureus. Results of this study indicated that the BSF extract (P3) has the highest phagocytic capacity value. This result proves that the BSF extract can induce macrophage cells to optimally process bacterial cells or foreign phagocyte particles. The highest average activity value, and phagocytic capacity of peritoneal macrophages was resulted from BSF extract (P3), respectively was 91.34 ± 0.38% and 22.84 macrophage-1 bacteria
Characterisation of M2e Antigenicity using anti-M2 Monoclonal Antibody and anti-M2e Polyclonal Antibodies
Full text linkMatrix 2 ectodomain (M2e) protein is a potential antigen for detection of influenza A virus infection in vaccinated poultry (DIVA test). However the M2e antigenicity and immune response it induces in either humans or animals are poorly understood. Seventeen M2e peptides and sixteen recombinant M2e (rM2e) proteins with amino acid (aa) changes introduced at position 10, 11, 12, 13 14, 16, 18 and 20 were compared by western blot (WB) and enzyme-linked immunosorbent assay (ELISA) using mouse anti-M2 monoclonal antibody (mAb) 14C2, and anti-M2e peptide chicken and rabbit polyclonal antibody (pAb). The mAb 14C had the best discriminating power and indicated that all six positions contributed to the M2e antigenicity. Position 11 was the important immunodominant and affected Mab14C binding to a greatest degree. Changes in the adjacent position 14, 16 and 18 also influenced the binding, and it detected regardless of the method (WB or ELISA), or the antigen used (M2e peptide or rM2e). For chicken pAb and rabbit pAb, the immunodominant aa was position 10 and the antibody reaction was not affected by aa change at 11. The binding of rabbit pAb was also affected by changes at 14 and 16, which confirm the contribution of these positions to the M2e antigenicity. Position 10 was the only important position for the binding of chicken pAb to M2e. Overall, the study showed that the M2e antigenic sites are located between residues 10 – 18 and that aa changes at position 10, 11, 12, 14, 16 and 18 may all affect the antibody binding within the M2e protein

Full text linkRecently the utilization of biological feed additives over chemical feed additives in animal feeds have increased. The objective of the present study was to evaluate the effect of supplementing wild guinea grass (panicum maximum) with two plant species, artocarpus heterophyllus (jack leaves; ah) and tridax procumbens (Tp) containing plant secondary metabolites tannin and saponin, respectively and the enzyme product dyadic cellulase (Ce) and yeast (Ye). For each suplement two levels of treatments were tested. In plant-based suplements 20 (Aht1, Tpt1) and 30% (Aht2 and Tpt2) substituted the base substrate. The enzyme was applied as 10 µl (Cet1) and 20 µl (Cet2) and yeast as 4 mg (Yet1) and 6 mg (Yet2). the experimental design was a randomized complete block design (rcbd) and the period of in vitro rumen fermentation incubation was 72 hrs. All treatments significantly (P 0.05) enhanced the in vitro gas production (Ivgp) compared with the control. Treatments of ah and ce significantly (P 0.05) improved the in vitro rumen dry matter degradability (ivrdmd). All treatments significantly (P0.05) suppressed the ruminal protozoa population as compared to the control. Ammonia nitrogen (Nh3-N) production was not significantly (P0.05) influenced with supplements. in conclusion, treatments enhanced the rumen fermentation in means of enhanced ivgp, ivrdmd and reduced protozoa numbers
Optimization of BS4 Enzyme production with Different Substrate Thickness and Type of Trays
Full text linkBS4 enzyme that is produced from solid substrate fermentation (SSF) on coconut cake with Eupenicillium javanicum BS4 in tray bioreactor has been applied as a feed additive. It increases the nutritional value of animal feedstuff. The BS4 production on SSF may be influenced by the better aeration through the perforated trays or by the thinner substrate. The aim of this research is to optimize the production of BS4 with different substrate thicknesses and types of trays. The trial was carried out using a factorial randomized design (2x2x3) with 6 replicates. The first factor was the type of trays: i.e., non-perforated and perforated tray. The second factor was the thickness of the substrate: i.e., 1.5 and 3.0 cm, while the third factor was the duration of fermentation: i.e. 5, and 7 days. The variables observed were moisture content, dry matter loss (DML), mannanase and saccharification activities, soluble protein content, their specific activities, and yield. Statistical analysis showed no interactions between the three factors, but there were interactions between types of trays and substrate thicknesses, as well as type of trays and incubation times on the mannanase activity and yield of mannanase. The results showed that DML was observed on day 7 were around 31.43- 36.89. The highest mannanase activity was observed on the non-perforated tray with 3 cm thickness on day 7. The saccharification activity towards palm kernel meal was better in the non-perforated tray on day 7 but not influenced by The yield value of mannanase and saccharification activities on a non-perforated tray with 3.0 cm thickness on day 7 was also the highest. Based on energy efficiency and the cost of production, it can be concluded that the optimum condition to produce the BS4 enzyme was observed in the non-perforated tray with 3 cm thickness and fermented for 7 days
