The current restrictions on the use of feeding methods are: First, to reduce the amount of feed; Second, control feed nutrient levels, reduce the nutrient concentration of the diet. The feed restriction period starts from 100 to 120 days and ends at 50 to 60 days before the start of production. The feed restriction phase is divided into two phases. In the first 30 days, the feed nutrient level should be gradually reduced during this period, from feeding 3 times a day to 2 times; increasing grazing time as much as possible, and gradually reducing the amount of feed each time. The average daily feed intake of female geese during the restricted-feeding period is generally reduced by 50% to 60% compared with the growth stage, and more feed coarse material is added to the feed for the purpose of exercising digestive capacity and expanding esophageal capacity. The crude protein level can be reduced to about 80% of the original level, and the feed can be used with 50% to 60% of the available grain feed, 20% to 30% of the bran feed, and 10% to 20% of the stuffing material. After the first 30 days of feeding, the weight of the reserve goose decreased by approximately 15% from the limit before feeding, and the feather luster gradually decreased. However, the appearance of the reserve goose should not change significantly, and the feed intake during grazing increased significantly. At this time, if the geese are in good health, they can be transferred to the post-feeding stage. Reserve geese through the feeding period of the pre-feeding phase of training exercise, the ability to eat grass increased, in a good grassland, animal husbandry, can not feed or less feed concentrate. In the control of the feeding stage, in the event of summer, in order to enable the geese to rest quietly at noon, the geese can be fed one lean meal at noon. In the case of poor grazing conditions, feeding should be performed twice, and the feeding time should be around noon and 21:00. Gooses prefer eating grass with dew, and should use as much time as possible to grazing in the morning and early evening. The end of the feed restriction period is 30 to 40 days. The feed formulation for this period is 40% to 50% for cereals, 20% to 30% for bran, and 20% to 30% for filling materials. The weight of reserve mother gooses allowed to control is reduced by 20% to 25%, the feathers are dull and their physique is slightly weak, but they have no pathological state, and their appetite and digestive ability are normal. No matter how many feeds are fed during the feed restriction period, the feeding time should be 2 hours before grazing to prevent geese from eating food before grazing without eating green grass; or feeding after 2 hours of harvesting, so as to avoid rearing after harvesting That is to say, there is a bad habit of eating raw material, eager to return to the nest and uncomfortable eating grass. Control points for the management of the rearing stage: Pay attention to the dynamics of the geese. For weak geese that can't tolerate restrictions, we must promptly discover and strengthen feeding and nursing. Grazing should be early and late, to avoid the heat of noon. The rest site should have a water source for drinking gooses and games. Prevent accidents. In high summer temperatures, thunderstorms should be prevented when grazing, and geese can be thrown into the water to avoid the threat of heat. In the evening, the geese can spend the night on the sports ground and open the doors of the geese and sports grounds. This not only facilitates ventilation and cooling, but also allows the geese to freely enter and exit. Lights should be lighted on the playground to prevent animal damage. In short, adopting scientific methods to restrict the rearing gooses is very beneficial to the development of geese production and to raising the economic benefits of geese.
