In high-temperature environments, particularly when the ambient temperature exceeds 25°C, laying hens tend to reduce their energy intake as a way to lower internal heat production. This behavior can lead to inadequate nutrient consumption, which in turn negatively affects egg production performance. To counteract this, it's essential to adjust the diet by increasing the concentration of nutrients. One effective strategy is to replace part of the carbohydrates with animal and vegetable fats, adding 1% to 2% of fat or oil to the feed as an energy supplement. Additionally, raising the protein level in the diet by 1% to 2% can help maintain productivity, while ensuring that amino acid balance remains intact to support overall health.
Juicy green feeds are highly beneficial due to their excellent palatability and rich vitamin content. They not only enhance feed intake but also contribute to better health and help prevent heat stress in hens. Including these feeds in the daily ration can be a practical and effective approach during hot weather.
Eggshell formation primarily occurs in the late afternoon and evening. Therefore, providing hens with a source of calcium, such as limestone powder or shell powder, during this time can significantly improve shell quality. This practice helps mitigate the negative effects of heat stress on both eggshell strength and hen well-being.
During summer, the early morning and late evening hours often have cooler temperatures, which coincide with higher feed intake levels in laying hens. Adjusting feeding schedules accordingly—such as offering feed just before turning off the lights in the morning and again at night—can maximize nutrient absorption and support optimal performance under challenging environmental conditions.
