Abstract

Cattle are an important component in a farming system in West Nusa Tenggara. Farmers' lives can hardly be separated from livestock, although the basic needs of the farm family are met from food crops. Cow dwelling system, especially in Lombok Island using cages gathering (collective cage), so the security of cattle more secure and coaching more easily implemented. The demand for cattle from West Nusa Tenggara continues to increase as the Bali cattle from West Nusa Tenggara are free from disease (Mouth, Nails, Brucellosis, and SE). Adaptability is quite good and high fertility and purity is more assured. The increasing rate of demand is expected to have exceeded the production capability, which tends to decrease the population of cattle. If the development of Bali cattle with integrated management based on collective cages applied to all areas in West Nusa Tenggara is expected to grow Bali cattle breeding centers in rural areas with superior production, uniform and continuous so as to support the provision of seed and beef cattle in West Nusa Tenggara . To find out the prospect of development of Bali Cow breeding centers on marginal land to support the supply of beef cattle in West Nusa Tenggara has been done by survey method from January to December 2012 in 10 regencies / cities as West Nusa Tenggara.

Abstract

This study aims to determine the presence of Salmonella thypimurium in spleen Balb / c mice given curcumin white turmeric (Curcuma zedoaria). The pure compound curcumin is thought to be an imonomodulator that will boost the immune system even though it has been infected using pathogenic bacteria. Oral administration for seven days is expected curcumin compounds have been entered in every body tissue, so it can optimize body function even if given the infection that will inhibit and disrupt the organ. This study used 24 mice with control treatment (aquadest), curcumin, curcumin and infection, the last infection alone. Infection was administered on day 7 by injecting a dose of 105 CFU Salmonella thypimurium on the intraperitoneal (Ip) portion. On the 10th day all mice were killed and their lept spies were aseptic for bacterial colonies observation. Observation of bacterial colonies in spleen of mice was done by plate method, cultured on selective medium of Salmonella Sigella Agar (SSA), After incubation for 24 hours (1 day) no bacterial colonies were found on SSA media. In each treatment either control, curcumin, curcumin and infections or infections alone. This is because the number of Salmonella thypimurium bacteria infecting mice is too small. By infecting mice using Salmonella thypimurium only 10% of the germs that can survive and live in the body of mice. 1 hour after intravenous or intraperitoneal infection, more than 90% of the inoculated germs are captured and destroyed by phagocytes. The remaining amount is only 10%, so generally this disease does not cause death.
