Crop damages by wild boar have been drastically increased in this decade in Ishikawa Prefecture. Comprehensive study against crop damage by them has been carried out for two years by three departments and one institute in Ishikawa Prefectural University. The environmental factors of crop damage were extracted by GIS analysis and MaxEnt model was used to predict where the damages break out. Microsatellite analysis revealed that most of wild boar population in Noto peninsula came from Western Toyama Prefecture. Questionnaire surveys for local farmers suggested that pasturage retarded crop damage by wild boars. Finally, using an appropriate disinfectant in the process of processing, transportation and consumption make it possible for us to utilize wild boar meat safely.

The consumption of rice has decreased and the amount of imported feed increased to produce animal products for last fifty years, which resulted in low self-sufficiency in food in Japan. The self-sufficiency dropped from more than 70% in 1960 to 40% in 2010. To improve the self-sufficiency in food, it is important to produce animal feeds in paddy fields in Japan. Whole crop rice silage is produced in more than 10,000 ha of paddy fields in Japan. The production will increase. It has the characteristics to contain higher vitamin E than the other feeds. The vitamin E content in beef produced by feeding whole crop rice silage was found to be higher than that in beef produced by feeding the other feeds such as rice straw to fattening steers. The higher vitamin E can prevent oxidation of fat in beef. It also can reduce the production of metmyoglobin by oxidation of myoglobin, which results in smaller change of color from red to brown in beef. Feeding whole crop rice silage to lactating dairy cows also increased vitamin E content in milk. These findings show the potential to produce higher quality beef and milk by feeding whole crop rice silage.
