Nongda #3 grain-saving small-size laying hen brooding stage feeding method

Abstract

The invention discloses a Nongda #3 grain-saving small-size laying hen brooding stage feeding method. The method comprises the following steps: before chicken enter a brooding coop, the brooding coop is cleaned and sterilized; heat supply is provided for preheating, such that the temperature in the brooding coop reaches 35-36 DEG C; an environment relative humidity is regulated to 62-67%; when the chicken enter the brooding coop, a density is 50-100 chicken / m<2>; a chicken feeding density is gradually reduced to 25-30 chicken / m<2>; after the chicken are hatched, the chicken should drink water for a first time within 24h; feeding is started after 24h since hatching; a Nongda #3 special-purposed brooding feed is used for feeding, wherein small amounts of feed are supplied frequently, such that the chicken can forage freely; clean drinking water is ensured, and water supply should be ensured day-and-night; corresponding illumination time and intensity, chicken coop temperature and temperature-humidity are adjusted according to growth progress, and ventilation is carried out regularly; when the chicken reach the age of 7-10 days, beak cutting is carried out; disinfection is carried out regularly, and the sanitation inside and outside the brooding coop is maintained; at the end of the 9th week, chicken weight reaches 0.55-0.58kg, and the chicken can enter growing stage management. The feeding method provided by the invention has the advantages of standard management and high survival rate. With the method, the growing chicken are robust. The method is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of poultry animal feeding, in particular to a method for raising Nongda No. 3 grain-saving small-sized laying hens during the brooding period. Background technique [0002] Laying hen farming is an important industry for my country's rural areas to become rich and farmers to increase their income. In recent years, the price of feed has been rising steadily, while the price of eggs has stagnated. As a result, the profits of laying hen farming have become increasingly meager, and some farmers have even lost money. In response to this phenomenon, the School of Animal Science and Technology of China Agricultural University has developed the Nongda No. 3 grain-saving small-scale laying hen. This kind of laying hen is small in size, but it can save feed. Its feed conversion rate is 15% higher than that of ordinary laying hens. -20%, it only needs 1 kg of feed to convert 0.5 kg of eggs, and the feed-to-egg ratio i...

AI Technical Summary

Problems solved by technology

However, due to the small feed intake of Nongda No. 3 laying hens, it is more difficult to raise than ordinary laying hens during the brooding period. Without certain methods and skills, it is easy to die in large areas. To improve economic benefits, we must first ensure the survival rate of laying hens. Therefore, it is very necessary for the majority of farmers to provide a feeding method with a high survival rate for the Nongda No. 3 laying hens during the brooding period
