Spring is the hen peak season of egg production. To achieve good breeding efficiency, the nutrients in the feed must be adjusted. There are four changes that must be made to feed adjustments for laying hens in the spring.
1. Changes in Energy Needs In the winter when the temperature of the laying hens is low, the metabolizable energy content is generally 2800 calories per kilogram. After warming temperatures in the spring, the energy feed will increase the body weight of the chicken, but it will affect the egg production rate. At this time, the metabolic energy contained in feed should be reduced to 2,700 kcal/kg, by reducing the proportion of energy feed such as corn.
2. Changes in Protein Requirements The hens consume more protein during the egg production period. Therefore, the crude protein in the feed should increase according to the increase in the egg production rate. When the egg production rate reaches 50%, the protein content is 15.5%. For every 10% increase in the egg production rate, the digestible protein in feed increases by 0.5%, but it should not exceed 18.5% at most. The method is to put more fishmeal and bean cake.
3. Changes in mineral needs The hens produce more eggs and the demand for calcium increases. Calcium in feed should be increased from 2% to 3% to 4%, and phosphorus from 0.5% to 0.6%. If indigestion and loss of appetite are found in layer chickens, salt content should be increased by 0.1%, and correspondingly added. Mineral additives.
4. Changes in vitamin needs Chickens increase egg production and increase vitamin consumption, and should be supplemented accordingly. In addition to the form of additives, the most important is to increase the proportion of various green feed in feed. The proportion of the green material in the feed was increased from 15% in winter to 32%. In the spring, chickens with an egg production rate of more than 75% should be fed with 15% pellet feed every night at 8 o'clock.
