Abstract

Marek’s disease (MD) is a neoplastic and neuropathic disease of poultry, especially chicken, caused by a highly contagious cell-associated herpesvirus. Marek’s disease is one of poultry diseases that is seriously concerned by poultry farmers. Before introduction of vaccine technology, the disease caused great economic loss in poultry industry, for example, in the United State the annual losses was estimated around $150 millions. Marek’s disease virus is relatively resistant to physical and chemical influence.  In  poultry  farms  the  virus  remains infectious  for  months  and  play  an  important  role  as  source of  infection. Pathogenesis of the disease is complex and influenced by factors. There are four phases of infection: early cytolytic infection, latent infection, second phase of cytolytic infection, and proliferative infection. Pathogenesis influenced by factors causes variety on clinical syndroms and incubation period of the disease in field condition. Successful disease control can be achieved, with vaccination as the main program, by selection of breed resistance and good management systems. The emergence of more virulent pathotypes of MD is a serious threat to the poultry industry, which requires development of more effective control strategies.   Key words.

Abstract

Banana weevil is a waste that has not been used much, however banana weevil has content lots of nutrition . So that need effort for utilise the banana weevil so that it can beneficial for society . This study used lactic acid bacteria fermentation method which aims to analyze the characteristics of modified banana weevil flour. Then thinly sliced banana weevil soaked for 2 hours inside sodium metabisulfite solution then soaked again use finished solution mixed with bacteria sour lactate with concentration 0;0,02;0,025;0,03 ml/L. After that hump dried and ground for become flour and tested characteristics . The results showed that the swelling power test level was highest at a concentration of 0.03 ml/L, which was 13.39 grams, the % solubility test was highest at a concentration of 0.03 ml/L with a value of 0.12%, the results of the viscosity test after being modified had the same value, namely of 1.4 mPa.s, for the results of reducing sugar content after being modified it decreased and a result of 4% was obtained.
