Key Technical Points for Feeding and Management of Foie Gras Geese During the Pre-feeding Period

Livestock Farming 0 views
Geese of around 12 weeks of age should be selected for foie gras production. At this time, the number of liver cells in geese is relatively high, and the activity of fat-synthesizing enzymes in the liver is relatively strong, which is beneficial for rapid liver weight gain. Before 2 weeks of age, goslings are mainly raised with roughage and grazing to reduce feeding costs. The pre-feeding period is the transition from grazing to housed feeding, and from roughage to concentrate feeding. The quality of feeding during the pre-feeding period directly affects the production results of foie gras. The key to feeding during the pre-feeding period is to let the geese have a gradual adaptation process, so that they adapt to a high-nutrition diet and adapt to a large amount of concentrate feed.

The key to feeding during the pre-feeding period is to let the geese have a gradual adaptation process, so that they adapt to a high-nutrition diet and adapt to a large amount of concentrate feed.

I. Change of feeding method After foie gras geese enter the pre-feeding period, the grazing time should be gradually shortened, and they should be changed to supplemental feeding of green roughage and concentrate in the barn and exercise yard. After 1 week, grazing is stopped and they are completely converted to housed feeding.

II. Feed During the pre-feeding period, the amount of green roughage fed should be gradually reduced, and the amount of concentrate feed should be gradually increased. The concentrate feed formula is: corn 60%, wheat bran 15%, soybean meal 18%, peanut meal 5%, bone meal 2%. After mixing with water to moisten, let the geese eat freely. When the daily feed intake reaches 250-300 grams and body weight increases by 10%, switch to the force-feeding period. The pre-feeding period is generally 7-10 days.

III. Do a good job of immunization One week before force-feeding, vaccinate with fowl cholera vaccine, with 1 milliliter injected intramuscularly per bird.
