This research was aimed to evaluate the use of high crude fibre feed on the characteristic of the native chicken digestive tracts. The research was conducted in Tembuku District, Bangli Regency in April-August 2020. There were four treatments starter diets included P0 (control), P1 (70% control feed+30% rice bran), P2 (70% control feed+30%+ Bio B 2cc/l drinking water), P3 (60% control feed+10% Indigofera meal+30% rice bran), while four treatment grower diet included P0 (25% control feed+35% rice bran+40% corn), P1 (15% control feed+35% rice bran+10% Indigofera meal+40% corn), P2 (15% control feed+35% rice bran+10% Indigofera meal+40% corn+2cc/l Bio-B), and P3 (22% control feed+31.5% rice bran+10% Indigofera meal+36.5% corn). The variables observed included final body weight, digestive tract weight, and digestive tract length. A factorial randomized block design was used in this study with univariate analysis and further Duncan test. This study showed that high crude fibre feed affected the digestive tract, such as the weight of the duodenum, jejunum, ileum, cecum, liver, pancreas, proventriculus. This also occurred in the parameters of the length of the duodenum, jejunum, ileum, cecum, and colon.

Native chicken is one of the livestock that is widely maintained in rural areas in Bali, to fulfil meat and eggs as a food consumption and also for religious ceremonies. However, the population of native chicken continues to decline until 4.15% in average every year due to high price of feed and nature behaviour of the chicken that picks food either by mouth or legs causes a lot of food to be wasted. To minimize the amount of wasted food, given the wet form of feed given in accordance with the needs for production. The study was carried out in Tembuku Subdistrict, Bangli Regency, using 90 laying hens which were divided into 3 group of treatments each with 30 chickens and differentiated between wet feed and dry (ordinary) feed. Where P0 is control, P1 is given Bio L Probiotics 3 cc.liter-1 of drinking water and P2: P1 + Herbs 4 cc.liter-1 of drinking water. The results showed that P0B: 56.71% P0K: 57.54%; P1B: 58.9; P1K 59.73% and P2B: 61.08; P2K: 60.15. The highest productivity were found at P2B and P2K. While the FCR achieved by each treatment were P0B: 3.35; P0K; 3.56; P1B: 3.07; P1K: 3.24 and P2B: 2.98; P2K: 3.13. These results indicate that the providing of wet feed produces a lower FCR than dry feed. The providing of Bio L probiotics could increase productivity

ABSTRAKPembangunan peternakan merupakan bagian dari pembangunan sektor pertanian yang memiliki nilai strategis dalam memenuhi kebutuhan pangan terutama protein hewani yang semakin meningkat. Pembangunan pertanian saat ini telah berubah dari dominan penyediaan karbohidrat menjadi berimbang ke arah penyediaan protein hewani. Hal ini juga terkait dengan meningkatnya pendapatan perkapita masyarakat di Indonesia. Ternak sapi adalah salah satu penyedia protein hewani terbesar dan merupakan ternak ruminansia yang mengkonsumsi hijauan berupa rumput, leguminosa dan juga daun-daunan dari pohon. Hijauan pakan yang tersedia di lapangan juga sangat tergantung dengan musim. Kajian ini dilakukan di desa Belanga Kecamatan Susut Bangli, menggunakan 13 jenis hijauan pakan ternak yang ada di lokasi. Penyusunan ransum didasarkan pada kombinasi ketersediaan sumber pakan yang didasarkan pada kebutuhan nutrisi ternak agar produktivitas tetap terjaga. Kombinasi komposisi hijauan pakan ternak lokal pada bulan Nopember sampai April kandungan TDN dan proteinnya mencapai 57,03% dan 12,68%, sedangkan pada bulan Mei sampai Oktober TDN dan proteinnya mencapai 57,03% dan 12,67%.

Swine cattle have high economic advantages and social values ​​ in Balinese society. This study aimed to determine the effectiveness of Enterotoxigenic Escherichia coli (ETEC) vaccine in gestating sows. We used 26 gestating sows aged 1.5 years old at their last trimester assigning 13 sows in the control group and 13 sows in treatment group to receive multivalent ETEC vaccine twice: on the 70-75 days of gestation and a booster on 100-105 days of gestation. Sows with the vaccine treatment divided into 3 group that groups A was treated antifimbrial K41, groups B was antifimbrial 987P, while in group C was Antiimbrial K88. The changes in temperature were observed from one day before to 4 days after vaccination in a randomized block design. To determine the antibody formed, blood samples were taken one and two weeks after the first vaccine and five weeks after the booster. The blood sample was analyzed by the Enzyme Linked Immunosorbent Assay (ELISA) technique. The rates of diarrhea and postnatal mortality were also observed. The results showed that the antibody titer level increased significantly in the fifth week in groups A with titer 1,94 ±0,22 and B with titer 1,98 ± 0,30 , while the number of diarrhea incidents was 0.9% compared to control 34% with a mortality rate of 0%. In conclusion, this multivalent ETEC vaccine is safe to use and has been shown to be effective for ETEC cases in swine.
