Feeding of Fatty Liver Goose in Pre-feeding Period
Geese about 12 weeks old should be selected to produce goose fatty liver. At this time, the goose has a large number of hepatocytes and a strong activity of fat synthase in the liver, which is beneficial to the rapid weight gain of the liver. Before the weight of 2 weeks old, geese were mainly raised by rough feeding and grazing in order to reduce the feeding cost. The pre-feeding period is the transitional period from grazing to house feeding and from rough feeding to intensive feeding. The quality of pre-feeding period directly affects the production effect of fatty liver. The key to the pre-feeding period is to let the geese have a gradual adaptation process, so that the geese can adapt to the diet with high nutrition level and to the large concentrate feed.
1. After the Feigan goose enters the pre-feeding period, the grazing time should be gradually shortened and the green roughage and concentrate should be fed in the house and in the playground. The grazing was stopped after 1 week and changed to house feeding completely.
Second, during the pre-feeding period, the feeding amount of green roughage should be gradually reduced and that of concentrate fodder should be gradually increased. The formula of concentrate feed is: corn 60%, wheat bran 15%, soybean meal 18%, peanut meal 5%, bone meal 2%. Let the goose feed freely after being wet. When the daily feed intake is 250-300 grams, the body weight increases by 10%, which changes to the filling period. The pre-feeding period is generally 7-10 days.
Third, do a good job of immunization one week before feeding, inoculate avian cholera vaccine, each intramuscular injection of 1 ml.

How to reduce the breakage rate of eggs in high temperature season
The problem of breakage of eggs has been plaguing every chicken farm, especially in the high temperature season, where the temperature is high, the preservation time of eggs is short, and damaged and contaminated eggs deteriorate within 2 days and cannot be sold. Therefore, this paper introduces several methods of how to reduce the breakage rate in high temperature season: the physiological characteristics of environment and temperature determine that the ideal temperature for laying hens is 18 ℃-23 ℃, and the production performance is the best in this range; when the temperature exceeds 30 ℃, the feed intake of laying hens decreases, the amount of drinking water increases, and feces increases.
