Laying chicken summer high yield measures
Summer temperatures are high and last for a long time, and egg production in chickens is extremely common. To maintain a high egg production rate, the following measures should be taken. 1. Do a good job in cooling the house (1) Increase ventilation in the house. Install ceiling fans or ventilation fans in the house to increase mechanical ventilation. This not only reduces the temperature inside the house but also reduces the concentration of harmful gases in the house. (2) Avoid direct sunlight in the house. Cover the top of the henhouse with straw and plant shade on the sunny side of the shed. (3) Spray water in the house. When the temperature inside the house is too high and the humidity is not too high, water can be sprayed into the house or on the roof, and the temperature can be reduced by 3-4°C. 2. Adjust diet formula timely (1) Reduce energy feed appropriately and increase protein content. In the diet, the proportion of corn can be reduced by 5-10%, and the ratio of bran and bran can be appropriately increased. At the same time, the proportion of soybean meal should be increased by about 5%, and the protein content should be about 22%, to avoid the decrease of feed intake of laying hens. Insufficient protein. (2) Properly increase the proportion of calcium. In general, calcium can be fed alone in the afternoon, accounting for about 4% of the feed, in order to improve egg shell quality and reduce the effects of thermal stimuli. (3) Appropriate feeding of green feed. When the temperature is high, fresh Green Vegetables, melon skin and other green and juicy feed can be fed. This stimulates the appetite of the chicken, reduces the cost of feed, and can also increase the chicken production rate. (4) Add heat-resistant additives to the diet. For example, add 0.4% baking soda, 0.3% of vitamin C and so on. 3. Provide enough clean drinking water. In summer, laying hens drink about 6 times their body weight. If conditions permit, use the lotus leaf or Hokkien decoction for the chicken to drink. 4. Change the feeding method. Feeding can be done sooner or later, and only feed some green fodder in the afternoon. 5. Do a good job of epidemic prevention and control work. In addition to the addition of drug control in the feed, we must also do a good job in the disinfection of chicken houses. It is best to use chicken spray disinfection when disinfecting, that is, to achieve the purpose of disinfection, but also reduce the temperature. 6. Reduce breeding density. The reasonable breeding density is 3-4 eggs per square meter, and cage chickens should be reduced by 30%, which is beneficial to the heat dissipation of chickens and can prevent the occurrence of snoring.
