Eggs in autumn catch high yield
Autumn is the season when new hens start production and the old hens moult. In order to ensure the high yield and stable production of new hens, the old hens should be moulted quickly and resume egg production as soon as possible. The following measures must be taken: 1. The feed quality of the old hens should be better in the early stage of moulting, and the diet should be relatively stable and not abrupt. change. Captive chickens should be fed with chopped, fresh, juicy green feed as long as the proportion of bran feed is properly reduced. When the chickens are moulted in large numbers, sufficient protein feed must be fed, especially feeds containing lysine and methionine such as fish meal, corn, and bean cake. In addition, appropriate amounts of raw gypsum or trace elements should also be added to the feed. Second, the mandatory moulting layer of natural moult in autumn, generally have to stop production for 4 months, and the use of artificial mandatory moulting, generally in the layer of chicken open about 10 months. The conventional practice is to stop the water for 3 days, stop for 10 to 12 days, and stop the light during the food stoppage. Third, supplementary lighting artificial supplement light should start from late September. New hens usually hatched from April to May do not need to be supplemented with light. New hens hatched from January to February when the egg production rate reaches the peak need to be supplemented with light, but artificial light and natural lighting time The sum of no more than 14 hours; re-production of hens from September to October if you still maintain stable production and high yield, you can extend the lighting time, so that the peak egg production time of light to maintain at about 14 hours. If the production of layer requires 14 hours of light time, a 40-watt incandescent lamp can be suspended every 13 to 14 m2 in the house, with a height of about 1.8 meters. Turn on the light at 6 a.m. and turn it off at dawn. Turn on the light in the evening and turn off the light at 8 p.m. IV. Adjusting the chickens After the moults of laying hens have a period of rest, chicken farmers should make full use of this period of time. According to the chicken turnover plan, those poorly-developed, weak constitutional and low-laying laying hens should be eliminated in time. At the same time, supplement the new hens cultivated in the year so that the chickens always maintain a strong and high yield, and obtain better economic benefits.
