Application Of Electronic Identification In Dairy Cow Management And Disease Prevention

Electronic identification, being a burgeoning RFID (Radio Frequency Identification) technology, has been widely used in many areas of person identification, goods transportation management, anti-counterfeiting, traffic management and animal management and so on, since its own outstanding advantages, such as huge storage, quick read-write speed, high data security, convenient usage and long read-write distance.In recent years, many countries suffered from great economic loses in animal breeding industry, due to the several outbreaks of serious animal epidemics, and a succession of food safety incidents caused by pathogenic microbes, animal medicine residues, and feed additive residues. The traditional food safety control system is being challenged and the new corresponding mechanism, that is "from farm to table "system, is impelling each country to establish an effective animal and animal product traceability system, so as to manage and monitor the whole processes of animal feeding, transportation, slaughter and animal product processing and selling. Under the background, the electronic identification technology just meets the needs of those countries, which are building animal and animal product traceability system.Basing on a large scale of literature materials and considering the actual needs of animal breeding industry in Shanghai, the study tried to offer and build a relatively complete electronic identification management system in cow farm.1. Referring to the relatively matured foreign technology, and basing upon the needs of veterinary government and cow farm in Shanghai, the study offer and build a RFID-based electronic identification management system in cow farm, which was composed of cow electronic identification, automatic accurate feeding system, computer network and applied software. The main purposes of this study, on the one hand was to be used in single animal identification, improving animal epidemics control ability, strengthening animal immunity and quarantine management, on the other hand was to increase the ratio of feed to milk and bring more economic benefit for industries by automatic accurate feeding system. After building the system, we made a analysis of the automatic accurate feeding system and animal epidemics prevention management system in three large-scale cow farms in Shanghai.2. A new automatic accurate feeding management system based on the electronic identification system was implemented in two large-scale cow farms by analyzing the differences in the amount of consumed concentrated feed, the output of milk and the ratio of concentrated feed to milk between the experiment and control groups. The results demonstrated that the average consumption of concentrated feed in experiment group in each dairy had a significant decrease of 9.3% and 11.7% compared with that in respective control group. However, the average amount of produced milk increased significantly by 4.8% and 4.1% and the ratios of the amount of concentrated feed to the amount of milk in two experiment groups were 11.5% and 17.8% down incomparison with their controls.3. To evaluate the accuracy and immediacy of the recordings of epidemic diseases as well as the scientificity and reliability of immunization after the application of the animal epidemic prevention management system based on electronic identification, an experiment was conducted in a large scale cow farm. The immune antibody of FMD was detected in the farms.The results showed that the positive rate of immune antibody is 100%,and the antibody titer is higher(logm2⁹.82 ) in experiment farm. However, the positive rate of immune antibody is 86.88%,and the antibody titer is lower(log₁02!8.40 ) in those control farms.Based on the controllability and traceability of electronic identification, this study incorporated the cow feeding and animal epidemic prevention management into the electronic identification management system in order to meet the development of increasingly mature inner market as well as international market.The experiment preliminarily confirmed th...
