(1) Purpose of food restriction 1 The core is to control the growth of chickens and maintain the standard weight: the main reason is that the weight of the chicken with too small fat accumulation is too limited to the small, fat and easily formed weight in the late growth period. To lay the foundation for increasing egg production. 2 Inhibitory maturation: Restricted feeding can make sexual maturity timely and synchronous. It controls the development of the ovaries, and is neat and tidy. The number of days required to reach an egg production rate of 50% is short. 3 Conserve feed: It can save about 10% compared with free food intake. 4Reducing the mortality rate during the production period: The feed restriction has the effect of nurturing and protecting the animals, which reduces the mortality rate during the production period. 5 Ensure normal body fat accumulation: Remove more than 4% of body fat to help increase egg production. 6 Improve group weight uniformity (2) Feeding conditions and methods 1 conditions: excessive weight chickens. Generally more than 10% of the standard body weight; strictly control the period of limited feeding. Generally 14W before opening. In China, the current level of energy consumption of laying hens is generally lower than the current level of foreign standards, generally do not limit the use of feed or the use of restricted feed. 2 Restricted feeding methods One is a limited method: 10% to 20% reduction in free intake; specific methods: daily intake, 1W stop 1d or 3d stop 1d, stop the water, stop feeding more, the greater the feeding limit. The second is the method of limiting the quality: that is to reduce the dietary energy and protein, amino acid levels, appropriate increase crude fiber. 3 Restrictions on Feeding: Strict implementation of feed restriction programs and restricted feed targets. Generally less than 10% to 20% of the body weight of feeding chicken; reduce stress, epidemic prevention and so on. The food trough is sufficient to ensure that each chicken has enough slots for food intake; the body weight is strictly monitored and the body weight changes are detected from time to time during the restriction period. Pick out the sick chickens. 3, adequate, clean drinking water Ensure that each bird has enough drinking water (3cm). 4, feeding gravel Helps the gravida (sandwich) to grind the feed, 2 to 3 kg per 1,000 chickens per week; grit size: 4 to 6 mm in diameter. 2004-2021 New Laser Distance Sensor
