In winter, the egg-laying performance of hens tends to decline due to lower temperatures and reduced daylight hours. At the same time, their overall nutrient requirements decrease because of a slower metabolic rate. Therefore, it's important to adjust the feed to meet these changing needs while focusing on maintaining and promoting feather growth, which is crucial for insulation and overall health.
To achieve this, the feeding strategy should be refined and more balanced. This means reducing the proportion of high-energy concentrates such as corn, sorghum, fish meal, and soybean meal, and instead increasing the amount of roughage like cereal husks. Additionally, incorporating green and juicy feeds—such as cabbage, celery, and carrots—can help improve digestion and provide essential vitamins and minerals.
A recommended feed ratio could be 15% fine feed (concentrates), 75% roughage, and 10% green feed. This combination helps maintain energy levels without overfeeding, while also supporting feather development and gut health.
It's also essential to ensure that the diet is nutritionally complete. Layer hens require a wide range of nutrients, including minerals, vitamins, trace elements, and amino acids, all of which play a vital role in feather formation and overall physiological functions. Especially for hens kept in cages, extra attention should be given to their mineral intake.
To support feather growth, each hen should receive approximately 2 grams of sulfur, 3 grams of gypsum, and 1 gram of feather meal daily. These supplements can help enhance feather quality and promote faster regrowth, especially after molting or during periods of stress.
By making these adjustments, you not only support the hens' health but also improve their resilience to cold weather and maintain better productivity throughout the winter season.
