The current limited feeding methods include: first, reducing the amount of feed; second, controlling feed nutrient levels and reducing the nutrient concentration of the diet.
The feed restriction period starts from 100-120 days and ends at 50-60 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 level of crude protein can be reduced to about 80% of the original level, and feed can be used with 50%-60% of cereal feed, 20%-30% of bran feed, and 10%-20% of stuffing. 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 pre-feeding phase of the feeding training, the ability to eat grass increased, in a good grassland, animal husbandry, can not feed or less feed concentrate. In the control feeding stage, in the event of midsummer summer, the geese can rest quietly at noon and can feed the lean feed 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 feed restriction period is 30-40 days later. The feed formula for this period is 40%-50% for cereals, 20%-30% for bran, and 20%-30% for filling materials. The weight of reserve goslings allowed to control feeding was reduced by 20% to 25%, the feathers were dull, and the constitution was slightly weak, but no disease state, normal appetite and digestive ability.
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 feeding stages: Pay attention to the dynamics of geese. For weak geese that can't tolerate feeding, 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 playground and open the doors of the geese and sports grounds. This not only facilitates ventilation and cooling, but also allows the geese to enter and leave freely. Lights should be lighted on the playground to prevent animal damage.
In short, using scientific methods to restrict the feeding of grazing gooses is very beneficial to the development of geese production and to raising the economic benefits of geese.
