Using radio frequency identification (RFID) technology for dairy cattle electronic management and traceability
The Radio Frequency Identification (RFID) technology included RFID electronic ear tags, reader, data wireless transmission, and information network.There were 10 dairy farms using Radio Frequency Identification (RFID) technology for their dairy herd electronic management. The selected RFID electronic ear tag is passive read and UHF sealed by polyurethane material and is hang up at the inner part of right ear of dairy cow. All data of cow’s ID and current date would be collected without any hand-writing. The date data would use the system of PDA, After finish collecting data at barn, data would transfer to the farm office computer automatically and all information of DHI would be download from DHI records database through network. Applications of RFID technology on the dairy farm help herdsman collecting data without time-consuming and paper reports, and using information in time with automation, accuracy.

Wireless web based system for dairy farm management
The Wireless Web based System for dairy farm was integrated by Radio-Frequency Identification (RFID), ear tag and reader, handhold data collection device, such as tablet PC and wireless internet access environment. Farm manager can use remote web programs on farm for real-time data audit through RFID reader on handhold device. Data transfer was through wireless broadband router, fast Ethernet switches, outdoor omnidirectional antennas or boosters which built the on farm WIFI wireless internet access environment. Remote MS SQL server database is in Livestock Research Institute, Hsin-Chu Branch, Council of Agriculture. Data inquiry is the major service in this phase demonstration. RFID reader reads animal identification to handhold device, and which can inquire associated data from all kind of active web page programs through WIFI network on farm. In next phase, the project will implant data edit or data insert services. The Wireless Web based System environment for dairy cattle can enhance decision information providing, dataflow and management efficient for dairy farmers.

Application of chilled water for alleviating heat stress in dairy cows
The aim of this study was to evaluate chilled water for alleviating heat stress on cows n lactation. Across-over design with an experimental period of 28 days and same feeding management was conducted with 8 cows whose milk yield averaged 21.2 kg per day. Eight cows were divided into treatment (n = 4) group and control (n = 4) group. Cows were provided with chilled water (23℃, treatment group) and ambient water (28℃, control group) through drinking and sprinkler. During trial period, the dry matter intake, milk production, milk components and somatic cell count as well as triiodothyronine (T3) and thyroxine (T4) of cows were measured. Respiration rate (at the 2 p.m.) and rectal temperature (at the 8 a.m., 2 p.m. and 8 p.m.) were measured from 4 cows per group. The results showed that the average the dry matter intake, milk production, milk components and somatic cell count of treatment group was not different from control group. Yet we found that treatment group had significant decline in respiration rate (-14.4 ± 3.2 vs.-2.8 ± 2.7 breaths/min，P < 0.05) and rectal temperature (-0.22 vs. -0.08℃, P < 0.05) than control group. In serum assay, the concentration of T3 and T4 showed no significant difference between treatment group and control group.

The mechanism of using Chinese herbal medicine to control the mastitis pathogens
The study was conducted to decrease the high somatic cell count Chinese herb medicine which possessed functions of anti-inflammation, (SCC) and bacterial count in dairy cattle by using Chinese herbs. This anti-fever and analgesia was used and ground as powder form. The dairy cows that SCC and bacterial count (E. coli) in raw milk were over 500,000/ml and 20,000/ml, respectively, were fed concentrate with Chinese herb medicine powder. Trial dairy cattle were divided into two groups. Each cow was fed Chinese herb medicine everyday in treatment group. Each experiment lasted 28 days. At start and end of the experiment, we measured the SCC, bacterial count, fat, protein, and lactose of milk in cows. In vitro, we measured the TNF-α, I L-1β, IL-8, and NO for the supernatant of leucocytes that were LPS (10μg/ml) was added either alone or with various concentrations of herbal extract. The cytokines TNF-α and IL-1β mRNA expression levels by using RT-PCR assay. The aim of our experiments is using Chinese herb medicines to decrease SCC and bacterial count in raw milk and to treat mastitis.

The relationship between milking curve and somatic cell count mastitis
According to the season, hot season and cold season is divided into two experimental period. Chose 18 cattles which in peak lactation (2~5 months), and in good health, without hoof disease, breast full of milk cows as the experimental cattle. Use of automatic milking test equipment, measuring individual cattle milk yield and the milking velocity. Collected milk samples to send DHI laboratory testing of milk somatic cell count, as the basis for the occurrence of mastitis. Followed by analysis of correlation between individual cattle milk yield, milk somatic cell count and the milking velocity. Another measured the teat shape of every cattle, including around the perimeter of the teats,the teats length, and the anatomy of the nipple with the teat wall thickness and teat canal length, then analysed the correlation between teat shape, milk somatic cell count and the milking velocity. The results showed that the correlation coefficients among milk yield, milk somatic cell count, and milking velocity are very low. (The correlation coefficient between milk yield and milking velocity is 0.155, the correlation coefficient between milking velocity and milk somatic cell counts is 0.093, the correlation coefficient between milk yield and milk somatic cell counts is -0.144. ) In terms of the correlation among teat shape, milk somatic cell counts, and milking velocity. The correlation coefficient between teat wall thickness and milking velocity is 0.299, the correlation coefficient between teat wall thickness and milk somatic cell counts is 0.348, the correlation coefficient between the perimeter of the teats around and milk somatic cell counts is 0.288. While the other correlation coefficients between traits wrew relatively low.

Assessment wireless sensor network system on dairy farm and remote management
Exhaustive record dairy cows barn inside and outside environment temperature, relative THI and wind speed and wind direction of the various seasons in dairy farm. Use the cow detection vibration sensory to detective the cows each hour vibration times every day. Accroding to the cows vibration times in before oestrus, being oestrus and after oestrus breeds to statistics the active time at the midnight to early morning period, to make a decision of the best mating times. Use the low temperature sensory to detective the milk tank temperature and control the milk quality change. If milk tank temperature rise to 5℃ above time,the low temperature sensory will through the WSN monitor to warning the farm management to make the emergency treatment.

Study and application of liquid fertilizer transformed from surplus milk by fermentation
This experiment was using surplus milk for fermentation by pump air at fixed time under room temperature. The tendency of pH, conductivity, content of nitrogen, phosphoric anhydride, potassium oxide, calcium oxide and magnesium oxide were the same between centrifuge and non- centrifuge group during storage. The pH decreased steadily, however, conductivity and content of nitrogen were increased remarkable. And variation of phosphoric anhydride, potassium oxide, calcium oxide and magnesium oxide were very small. Change of metals included copper, zinc, cadmium, nickel, chromium and lead were unobvious. Content of nitrogen and total amount of nitrogen, phosphoric anhydride, potassium oxide in non-centrifuge group were superior to those in centrifuge group until third month. The experiment needs to repeat in other seasons.
