A surveillance of gastrointestinal nematode and lungworm infections in 188 Holstein heifers was conducted in the public pasture on Toyokoro Town in Hokkaido using two fecal examinations before and after ivermectin pour-on was administered. In the initial fecal examination, 93.1% of cattle had gastrointestinal nematode eggs. In the second fecal examination which was conducted on one and half month after the initial examination, cattle positive for gastrointestinal nematode eggs decreased to 71.8% and the average EPG also decreased significantly (p<0.05) . Coccidial infections were observed in 187 of 188 cattle in the initial examination and this did not decrease in the second examination. The results of this survey indicated that some measure need to be taken against parasite infections in pasture cattle including coccidial infection.

The relationship between the concentration of serum insulin-like growth factor-I (IGF-I) and changes in body weight was studied in a total of 169 Holstein cows from 30 days before to 40 days after parturition. The concentration of serum IGF-I decreased after parturition and then increased again gradually. Lactating cows with low concentrations of serum IGF-I had decreased body weights and daily milk productions during a month. However, these cows had normal ranges of total protein, GOT, GPT, triglyceride, total cholesterol, non esterif ied fatty acids, BUN, and ketone bodies. These results suggested that the concentration of serum IGF-I in lactating cows might be related to changes in body weight and daily milk production. Serum concentrations of IGF-I might be useful and sensitive parameter for evaluating the condition of the liver and milk-production performance.

Recent rapid development of information technology has made Geographic Information System (GIS), that is capable of integrating, processing and analyzing geographic information, a useful and practical tool for scientists and policy makers in their scientific analyses and decision making tasks. This paper briefly summarizes the basic concept and history of GIS as well as its characteristics. The two most important functions of GIS, i.e. spatial search and spatial analysis, are also described with an example. Some examples on potential applications in veterinary sciences are included for better understanding of GIS for veterinary Scientists.
