The photoperiod is the period of daily illumination received by an organism. When manipulating photoperiods, there are two common divisions of time. The first is long-day photoperiod, with 16 hours of light and 8 hours of darkness. The second is short-day photoperiod with 8 hours of light and 16 hours of darkness.
According to the research published in the National Library of Medicine in 2021, it is known that the regulation of circadian rhythm through photoperiod and light intensity has a significant impact on the behavior and physiology of dairy cows. This article will discuss the benefits of applying different photoperiods for different stages of the cow's life cycle, and the benefits of agricultural lighting for cows and farmers.
Different Lighting for Different Stages of Cow
Lighting affects many aspects of a cow's production and life at different stages. The following are the benefits of applying different photoperiods for three stages of cows.
l Lactating Cows
Compared with cows exposed to natural light, applying long-day photoperiods for lactating cows can increase milk production by 10%-15%. On the other hand, lighting can also affect the dry matter intake of cows. Lactating cows under long-day photoperiods will consume 6% more dry matter than those under natural photoperiods. The increased dry matter intake can convert into milk, resulting in increased milk production of lactating cows.
l Prepubertal Heifers
The industry has always aimed to get heifers into the milking herd as soon as possible. Studies have shown that long-day photoperiods can advance heifers' puberty, allowing them to develop their height and mammary glands rapidly. Thus, heifers exposed to long-day photoperiods will have increased milk production during the first lactation. Additionally, stimulating heifers with proper lighting can reduce stress, increase feed intake, and lead to stronger, more productive cows.
l Dry Cows
The photoperiod is reversed in dry cows compared to lactating cows and heifers. Using short-day photoperiods during the dry period can increase cows' dry matter intake by 2.9 pounds per day. Dry cows will undergo extensive mammary gland remodeling during farrowing. Combined with eating a lot of dry matter, the dry cows that experience short-day photoperiods can increase milk production up to 6.8 pounds per day during lactation.
The Benefits of Agricultural Lighting for Cows and Farmers
Light, as an environmental factor closely related to organisms in nature, also affects the physiological functions of cows. According to the U.S. Department of Energy’s 2016 Animal Responses to Light Meeting report, providing adjustable agricultural lighting can enhance the growth and development of dairy cows at different stages. Moreover, agricultural lighting has also been shown to reduce stress and improve disease resistance in dairy cows, improving their productivity and well-being.
Lighting not only benefits the cows but also benefits the farmer. Agricultural lighting lasts longer and can withstand the harsh conditions in cowsheds, helping farmers reduce maintenance costs and workload. Furthermore, compared with traditional lighting, agricultural lighting can imitate the natural environment of life. For farmers, this means agricultural lighting can help them reduce eye strain, make them easier to concentrate and create a safer and more secure work environment.
