Analysis: The Positive Impact Of Blushield Devices On A Dairy Herd
25th Apr 2024
Upon arrival at the dairy processing plant, milk undergoes automatic testing to measure the level of somatic cells present. Somatic cells, which include white blood cells, naturally occur in all milk. Their concentration serves as a crucial indicator of milk quality and the overall health of the dairy cows. Typically, an elevated somatic cell count signifies that cows have been subjected to stressors such as illness or injury, triggering an immune response.
In a controlled study spanning several months, the effect of Blushield devices on the somatic cell count in a dairy herd was systematically evaluated. The herd was monitored under two conditions: with the Blushield device activated within the dairy barn and with the device removed. The findings revealed consistent outcomes; without the Blushield, the highest somatic cell count observed was 420, with an average of 360. Conversely, with the Blushield operational, the cell counts significantly decreased, achieving a low of 120 and an average of 140.
It's important to note that changes in somatic cell counts in cows are not influenced by psychosomatic factors; they are a direct response to physical health conditions.
Additional context regarding the environmental stressors faced by these cows includes their proximity to a TV mast installed in the 1970s in New Zealand. Prior to the installation of this mast, the local dairy cows displayed typical levels of health and behavior. However, following the mast's setup, noticeable increases in biological stress were observed. This stress was evidenced by a greater consumption of mineral-rich salt blocks and a rise in mastitis cases among the herd, along with an overall increase in somatic cell counts.
The introduction of Blushield devices around the year 2000 marked a turning point. Within approximately 10 days of activation, there was a notable reduction in somatic cell counts. Additionally, other stress indicators previously observed in the herd began to dissipate.
This data underscores the effectiveness of Blushield technology in mitigating environmental stressors affecting dairy cows, enhancing milk quality, and promoting animal welfare by stabilizing somatic cell counts. This promising technology offers a substantial benefit to dairy farm management, emphasizing its potential for improving dairy herd health and milk production efficiency.
