The rapeseed cakes are first fed to chickens
Rapeseed cake is a good protein feed. Feeding chickens can greatly reduce feed costs. However, the glucosinolates contained in the rapeseed cake easily produce toxic substances in the chicken body, and the palatability is poor, and the utilization rate is very low. Therefore, the following methods can be used for detoxification before using the rapeseed cake to feed chickens.
The method of pit burial is to dig a rectangular pit with a width of 80 centimeters and a depth of 80 centimeters in a place with good terrain and high soil quality (bogey shade). The length of the pit can be determined according to the number of rapeseed cakes. Spread 3 cm thick wheat straw at the bottom of the pit, then crushed into the end of the rape cake and water in a ratio of 1:1 mixing wet buried pit, top layer of thin wheat grass, and then cover soil 40 cm thick, open drain around To prevent the infiltration of rainwater, the pit can be used after two months. Note that mustard cakes that have become moldy should not be used as feed.
If the cooking method is used on a small scale, the crushed rape cake can be soaked in warm water for 8 to 12 hours, then the water is poured, and then the water is added for boiling for 1 hour. The stirring is continued until the glucosinolate is fully evaporated. .
