The study found that: properly designed lighting can raise cows milk production
from the source to feed the cow comfort, there are many factors affect the produce the milk of cows.
a few days ago, according to foreign media reports, the study found that lighting if designed properly, the milk yield can be increased by 6% 10%.
if dairy barn lighting time extension, then produce the milk of cows and feed intake will increase. Studies show that when the illumination time is 16 to 18 hours a day, the light intensity of at least 160 - The highest 200 lux, milk production.
the Westpoint Veterinary Group ( West veterinary group) Director Phil Elkins, said a long time of light is thought to increase the release of prolactin, and prolactin is the hormone responsible for milk production.
'the research shows that during the period of lactation, especially in early stage, compared with only 13 hours a day light herds, 16 hours of light cycle and 8 hours of dark lighting will production increase 2 liters per day. '
it is interesting to note that during the dry period, the opposite is true. 'At this stage, the illumination time is short, the best advice 8 hours of light and dark 16 hours lighting'.
in order to achieve this goal, need high quality, consistent lighting. 'Time for high illumination, farmers should be the level of illumination in the dairy barn evenly, 180 - The level of 200 lux. Dark period in lighting, lighting is likely to fall to 50 lux or lower. '
