Abstract

Matrix (M) and Non Structural (NS) proteins are smallest segments of influenza virus genome. The noncoding sequences at each end include the sequences of 11 – 13 nucleotides at the 5’ ends and 9 – 11 nucleotides at the 3’ end which are highly conserved between seven or eight different RNA segments and very similar for A, B and C influenza viruses. Protein of M1 is an essential structural component of the virion and participates in other steps during the replication of influenza virus. During early viral infection, dissociation of M1 from RNP is required for entry of viral RNP into the cytoplasm of the host cell. On the other hand, NS1 is a multifunctions protein that performs a plethora of activities, which may additionally contribute toward efficient virus replication and virulence during infection. The role of NS1 are temporal regulation of viral RNA synthesis, control of viral mRNA splicing, enhancement of viral mRNA translation, regulation of virus particle morphogenesis, suppression of host immune/apoptotic responses, activation of phosphoinositide 3–kinase (PI3K); and involvement in strain-dependent pathogenesis. This paper reviews the structure and role of two proteins i.e. Matrix and Nonstructural to understand the character of influenza virus especially in virulence and pathogenesis ability of virus other than hemagglutinin (HA) and neuraminidase (NA) protein as known. Key words: Influenza virus, matrix protein, non structural protein

Abstract

Important green house gases (GHG) attributed to animal agriculture are methane (CH4) and nitrous oxide (N2O), though carbon dioxide (CO2) contributes almost half of total greenhouse effect. Rumen CH4 production in an enteric fermentation can be accounted as the biggest anthropogenic source. Some of prebiotics and probiotics have been innovated to mitigate rumen CH4 emission. The possible use of agricultural biomass consisted of non-edible parts of crop plants such as cellulose and hemi cellulose and animal wastes was proposed as a renewable energy and nitrogen sources. The ammonia stripping from digested slurry of animal manure in biogas plant applied three options of nitrogen recycling to mitigate nitrous oxide emission. In the first option of the ammonia stripping, the effect of ammonolysis on feed value of cellulose biomass was evaluated on digestibility, energy metabolism and protein utilization. Saccharification of the NH3 treated cellulose biomass was confirmed in strictly anaerobic incubation with rumen cellulolytic bacteria, Ruminoccous flavefaciens, to produce bio-ethanol as the second option of ammonia stripping. In an attempt of NH3 fuel cell, the reformed hydrogen from the NH3 stripped from 20 liter of digested slurry in thermophilic biogas plant could generate 0.12 W electricity with proton exchange membrane fuel cell (PEM) as the third option. Key words: GHG, rumen, methane, probiotics, ammonia stripping, biomass

Abstract

Cassava and sweet potato leaves are agricultural byproducts which are potential to be utilized as feed for small ruminants. In year 2009, it is assumed that dry matter productions of cassava and sweet potato leaves are 2,590,929 and 348,008 tons, respectively. Cassava and sweet potato leaves, both contain high level of protein (> 20%) so that they are good protein sources for goats. Cassava leaves, however, contain cyanide acid (HCN) that varied depended on the age and require wilting process before fed to goat. Several experiments on utilization of cassava or sweet potato leaves for small ruminants showed positive responses on animal performance and could replace 50% of concentrate feed. Besides, cassava leaves can reduce worm eggs while sweet potato leaves contain high lutein. At present, the development of cassava and sweet potato is expected to provide feed as byproduct for ruminant. Key words: Cassava, sweet potato, feed resource, ruminant

Abstract

Shortage of beef supply to meet national needs is also found locally in North Sumatera Province. The trend  for beef in this area was triggered by the increasing of population, economic improvement and  desire for better nutrient comsumption. Level of beef consumption is increased 17% from year 2004 to 2008, so in the same period the number of cattle entered into the North Sumatera Province also increased. Some efforts had been conducted to develop beef cattle program in North Sumatera Self Sufficiency Program in Beef through technical and policy approaches. Several programs have been developed to accelerate the development of productivity and the population in North Sumatra, among others, 1) Agribusiness Development Program, 2) Food Security Improvement Program, 3) Farmers Welfare Program; which are financed by both central and local budgets. Institutional aspects that have been developed to support the PSDS-2014 is the Regional Artificial Insemination Center to serve the needs of semen for districts and municipalities in the Province of North Sumatera. In the year 2008, it has been distributed as many as 44 000 doses of semen for frozen semen to meet the demands of 11 Districts. The amount of land resources for development indicated the availability of pastural land area of 1,311,159 ha from oil palm and rubber plantation, area of 1,192,172 ha for crops and livestock integration system. It is estimated that biomass production of rice straw, bean straw and sugarcane straw reaches 7,062,227; 68 145 and 14 664 tons per year, respectively. Also available as many as 689,478 tons of rice bran and palm oil industry waste as much as 4,159,203 tons per year. Some challenges in the North Sumatera PSDS programs in accordance with a predetermined time include: 1) Not all of the stakeholders get a complete information about the program, 2) the difficulties to prevent productive cows being slaughtered, 3) limited capital in an effort to pick up and redistribute productive cows before slaughtered, 4) small scale ownership of cattle thus slowing the adoption of technological innovations.

Abstract

Listeria monocytogenes often contaminates food derived from animal and serves as pathogenic bacteria for animals and human. The outbreaks were related with the consumption of food derived from animals such as  meat, milk, egg, seafood and its product that poorly cooked. Human listeriosis could be transmitted by direct contact with infected animal. The disease often is asymtomatic and widely distributes in the world. The mortality rate reaches to 30%. The bacteria is important because of the widespread in the environment, tolerant to acid, hot or salt environments, forms a biofilm layer and produces virulent factor (listeriolisin O/LLO). The bacteria can grow at 4°C or in the frozen food. Appropriate handlings of animals and their products are important to prevent from L. monocytogenes contamination. Key words: Foodborne disease, L. monocytogenes, food derived from animal, listeriolisin O
