Summer geese refer to the last batch of goslings hatched in May and moved into the rearing area in June. During this time, wild grass is abundant, water bodies are rich with aquatic plants, and the temperature is ideal for natural brooding. By combining natural grazing with feeding on aquatic weeds, a cost-effective method is used to reduce feed expenses and improve economic efficiency. Below are the detailed methods introduced:
(1) Sheds should be constructed along lake embankments, ponds, reservoirs, and ditches. The water sources must be clean, and the pastures should be spacious. The slope of the grazing land should not exceed 30 degrees, and it's preferable to have trees nearby. The sheds should be easy to build, flexible, and quick to set up.
(2) Feeding Methods:
(1) Once the goslings enter the shed, they should be given a 0.01% potassium permanganate solution or brown sugar water to drink.
(2) Acacia grass is used as green feed. It should be washed thoroughly until the root is white, then dried on a special rack for several hours to allow surface moisture to evaporate, preventing diarrhea in the geese. The roots of the acacia should be cut off, and the remaining parts should be sliced into strips or filaments without using oil. Initially, the goslings eat less, but their intake increases over the next few meals. Feed them every 3-4 hours for three days, then allow them to rest after feeding to absorb the yolk.
(III) Grazing and Management Technology:
After 1-3 days of age, grazing can begin, allowing them to freely eat wild grass. Geese have a wide range of herbivorous food options. The grazing time should gradually increase, starting from short periods and moving to longer ones, and from close areas to farther locations. After short grazing sessions, return the geese to the shed. Early on, attention should be paid to temperature changes, especially at night, to prevent cold stress; someone should be on duty during the night.
After 1 week, the goslings' appetite increases, and grazing time extends. In particular, they should eat dew-covered grass in the morning. This stage requires continuous feeding, mainly with duck tongue grass, starting from small portions and increasing gradually until they no longer need to be cut.
At noon, collect a large amount of duckweed, drain it in two layers to avoid exposure. After a few hours, drain the first layer and feed it to the geese. Since geese have a fast stomach emptying rate, they often feel hungry quickly. If the weather is suitable, immediately let them graze to develop their foraging skills. The key management principle during this period is “full when hungry,†encouraging more exercise to enhance their immunity.
Harvest at sunset, feed the duckweed that was drained from the second layer, and leave some for the next morning’s grazing. When grazing, follow the rule of “goose put two lightly see†and try to return late. Use lights or candles for nighttime illumination.
Each day, rotate grazing areas to allow grass to regrow. Collect salamanders based on the geese’s feed intake daily. Make a plan for daily collection, avoiding storage or spoilage.
Early the next morning, due to hunger and thirst after the night, release water first before grazing, then sprinkle duckweed. During this time, geese have the strongest feeding ability. Around 10:00 AM, when the temperature rises, they are fully fed, and the grazing group should return to the shed for rest. In the afternoon, reduce grazing when the temperature drops.
At noon, collect and drain the salamander for feeding. This practice continues for 15-20 days, during which the geese grow stronger, develop better digestion of crude fiber, and can utilize plant proteins for self-assimilation. Seize this opportunity for full-day grazing while monitoring weather changes and returning to the shed promptly in case of high temperatures or heavy rain.
Geese prefer rainy and sunny days. They eat clean grass washed by rain and can drink from ditches while playing. Utilize these opportunities for grazing.
For a small number of sick geese, isolate them and provide supplementary feed like bran if needed. Return them to the group once they recover.
(D) Fattening Techniques:
After one month, the geese start to grow white feathers on their heads, tails, and wings, known as “four flowers,†weighing between 1.5 to 2.0 kg. During this period, feeding remains the main focus. Provide 4 to 6 tons of feed per day, as their appetite significantly increases.
During this stage, geese are in the phase of growing long feathers and bones. They become very active, running and chasing each other, so they must be prevented from escaping. Graze while feeding them duckweed, observing their feeding behavior. Their eating habits directly affect fattening results.
Harvest part of the early rice fields for free grazing. Allow the geese to forage small amounts of leftover grains initially to adapt their digestive systems, avoiding interference with later rice planting. Ensure they have enough water to drink. As temperatures rise, provide shade and cooling. Most geese should rest under trees or in shaded shelters. Move the sheds to the center of the grazing rice fields, where people and geese can sleep together. At night, use net enclosures to secure the geese for easier management.
After grazing in the paddy fields, the geese gain weight quickly, and two months later, they will have neat feathers, commonly called “wearing the big pheasant.†Their environmental adaptability improves, and grazing time should be extended.
(E) Disease Prevention and Treatment:
Before moving goslings into the shed, understand the local disease prevention status and administer the gosling plague vaccine on time. After one month of age, treat the geese with levamisole hydrochloride, giving 0.1g per goose per day for 3-4 days. Keep some common veterinary medicines ready to address any issues promptly.
