Reserve geese are young geese that have not yet started laying eggs or entered the breeding period, typically between 70 days of age and the onset of egg production. During this time, they are still in a critical growth phase and should not be overfed to avoid premature maturation.
Around 80 days of age, young geese begin their first moult, which usually lasts for about 30 to 40 days. Since they are still developing, it's important to gradually reduce feed quality and nutrition based on pasture conditions, allowing them to grow naturally without being forced into early maturity.
After completing the second moult, reserve geese should be provided with adequate feed to prepare for egg-laying, ideally around 50 to 60 days after moulting. At this stage, their physical development is still incomplete, and there may be inconsistencies in growth and egg-laying timing among individuals. To ensure uniformity, controlled breeding practices should be implemented, helping to regulate when each goose begins laying eggs. Male geese typically start showing sexual behavior after the second moult, so from 120 days of age, it’s recommended to keep males and females in separate groups to allow full maturation.
During the control period, feed levels should be gradually reduced, and feeding frequency can be decreased from three times a day to two. Extending grazing time while reducing feed portions helps improve digestive function and esophageal capacity. In general, female geese should consume 50% to 60% less feed during this period compared to the growth phase. Adding more bulk feed, such as grass or roughage, can help strengthen their digestive system. Geese grazing on good pastures may require less concentrate feed, while weaker or injured geese should be isolated and given special care.
Three to four weeks before the start of egg production, reserve geese should enter a recovery and feeding phase. During this time, feed amounts should be gradually increased to restore energy and support reproductive organ development. The timing of feed supplementation is flexible, but full-nutrient feeds should be provided to ensure proper preparation.
Before the production period begins, geese should receive deworming treatments and vaccinations. Following the recommended vaccination schedule, goslings should be vaccinated against diseases such as gosling plague, avian influenza, goose parvovirus, and goose lice. This ensures better health and higher productivity during the laying season.
