Melanin is a protein that exists in the basal layer of everyone` s skin. The exposure to ultraviolet radiation can cause changes in melanin, generating a substance that protects the skin. Then, melanin moves through the layers of cellular metabolism and reaches the epidermis of the skin, resulting in skin problems such as pigmentation and uneven skin color.
(1) The first step of whitening is to inhibit melanin production.
Melanin is the most important type of pigment that affects skin whiteness, and inhibiting the generation of melanin is the most important ultimate goal of whitening products.
(2) The second step of whitening is to block melanin transport.
After melanin is generated within melanocytes, melanosomes are transported along the dendritic processes of melanocytes to the surrounding keratinocytes, affecting skin color.
(3)The third step of whitening, stripping.
By softening the stratum corneum, these substances accelerate the shedding of dead cells in the stratum corneum and promote the metabolism of the epidermis, so that the melanosomes entering the epidermis fall off with the rapid renewal of the epidermis during metabolism process, thereby reducing its impact on skin color.

Preparation of pigeons before artificial feeding
The young pigeons, which hatch from eggs and are raised in nests for sale or breeding purposes, undergo a critical growth phase known as the "milk" period. During this time, they are fed for 25 to 30 days by their parents, who provide them with semi-digested food. These young birds, often referred to as squabs, go through a vital stage of development that requires careful attention and proper care. Ensuring their well-being during this time is essential for their future health and productivity.
1. Prevent "Feed Bias"
Feed bias occurs when one pigeon in a nest is significantly larger, stronger, or more dominant than the other. This can lead to unequal feeding and negatively affect the weaker pigeon’s growth. If you notice this issue, consider temporarily separating the stronger pigeon so the weaker one can eat more freely. Alternatively, you can swap their living areas to encourage balanced feeding.
2. Promote Digestion
Between day 9 and day 13 after hatching, the pigeons' diet transitions from a thick slurry to a soft mash and eventually to softened grains. This change can sometimes cause digestive issues such as crop stasis, indigestion, or throat inflammation. To help them adapt, you can start giving them a small dose of yeast tablets once a day starting at day 8. Additionally, offering easily digestible foods like rice, wheat, sorghum, and green beans can support their digestion during this sensitive period.
3. Side-by-Side Brooding
At around 10 days old, pigeons can be grouped together in pairs or small groups. This practice, known as side-by-side brooding, helps reduce stress and improves overall growth. If there's an imbalance between two pigeons in a pair, you can adjust by mixing them with others of similar age. This method promotes better feeding habits and increases the chances of successful breeding.
4. Early Weaning
By weaning the young pigeons at 7 days old and providing them with artificial feeding, you can shorten the breeding cycle. This early intervention allows parent pigeons to reproduce more frequently, ultimately increasing the number of offspring produced each year.
Proper care during the milk period is crucial for the long-term success of your pigeon flock. By following these practices, you can ensure healthy growth, better digestion, and higher breeding efficiency.
