Production and management of laying hens

Principles for rearing laying hens during the breeding period: All basic immunization work for laying hens should be done before opening, and at the same time, the insects should be dewormed to maintain a good body condition, high antibody levels and body resistance for entering the laying period. , to improve the feed conversion rate to make full preparations; do a good job of feed nutrition adjustment and lighting management to meet the production needs of laying hens.

1. The feed nutrition should be transferred from the rearing material to the egg production material, but it is necessary to adhere to the principle of gradual and orderly progress and to make a scientific transition from the rearing period to the laying period. The method is: 2/3 of the bred diet +1/3 of the egg-laying diet is fed for two days, 1/2 of the bred diet +1/2 of the egg-laying diet is fed for another two days, 1/3 of the bred The diet + 2/3 of the egg-laying diet was fed for another two days. Later, the diet was changed to the egg-laying diet. The entire transition period was completed in about one week. In the future, the increase in feed nutrition will increase gradually as the egg production rate increases, and it should not increase too much. Excessive increase in protein may increase the chance of dystocia and prolapse of the intestine due to too large a body of the egg, and if it is not detected in time, it will result in death from severe anal fistula. Shell or stone powder is added too fiercely, excessively, the layer cannot absorb, can only maintain the balance by increasing drinking water, strengthening body circulation and excreting excess minerals, not only increasing the burden of liver and kidney function, but also often leading to the occurrence of diarrhea. It is advisable to increase the amount of soybean meal and shells by 1% to 2% each time.

2. Add 2% shell or stone powder to the feed two weeks before the start of production to promote calcium and phosphorus reserves.

3. The attention should be paid to the balanced supply of feed rations. Special consideration should be given to energy-protein ratios, calcium-to-phosphorus ratios, and the synergy between calcium and sodium, as well as coordination and balance between various essential amino acids. It is usually appropriate to have a 17:1 ratio of energy to protein in the broiler.

4. Open production at a proper time. The important basis for the judgement of whether laying hens can start production is: weight and length (high), low weight, or short pod length (high) is not enough to start production, which tends to result in small egg body, short peak duration, and total egg production. Low, serious causes unnecessary loss due to dystocia. Therefore, the timing of opening the production must be based on the requirements of its varieties, and the weight and length (high) standards should be met to ensure that the chickens can be put into production when they are mature and mature.

5. Fill light and refueling must be synchronized. The egg weight of the hens to be raised and the length (length) of the hens can be transferred to the egg-laying period. The first week will be filled with light for 0.5 hour to 1 hour, and then the week will be increased by 0.5 hour to 1 hour until the sunshine duration. Stays constant for 16 hours.
