Fatty liver is a specialty of snail duck how to feed snail duck to obtain fatty liver

Fat liver is a specialty of mule duck. Mule duck can get high quality fat liver in a short time by feeding it correctly. The feeding technique of mule duck is introduced as follows:

snail duck

Selection of mule duck: the snail duck producing fat liver must be a large mule duck. There are three specific criteria: (1) the weight is more than 3 kg, preferably 3.5 kg;(2) the age is more than 70 days;(3) the body is strong, preferably the neck is thick and short, the chest is wide and the length is long, and the chest and abdomen are large.

Feed preparation: pouring corn into a pot, injecting clear water, immersing corn in water surface for 6-10cm, boiling, boiling for 5 minutes, stopping fire, taking out and draining water, adding 1-2% oil and 1% salt while hot, mixing well, and then feeding.

Feeding method: two people in a group, coordinated operation. First pour the prepared feed into the hopper of the feeding machine, then drive the snail duck to a corner of the feeding room, circle it with a fence, hold the snail duck to the front side of the feeding machine and sit down, put the snail duck on the bird fixing device under the stuffing tube, press the wings of the snail duck tightly with both thumbs, and hold the duck body with the other four fingers to prevent it from breaking free, and force the duck legs to extend backward. The feeder sits in front of the feeding machine. When filling, the stuffing tube is first smeared with edible oil to lubricate it. Then, the right hand grasps the duck head, and the thumb and index finger gently press the two sides of the duck beak base to force the duck to open its mouth. Then, the left index finger extends into the duck mouth, presses the tongue base, pulls outward, pulls out the duck tongue and fixes it. Then, the stuffing tube is inserted into the duck beak and slowly moves upward until it enters the enlarged part of the duck esophagus. At this time, the feeder fixed the duck head with his left hand, stepped on the switch with his left foot, and the feed in the feeding tube entered the duck esophagus. The right hand stroked the lower part of the duck neck, so that the feed entered and filled the enlarged part of the esophagus.

Pre-feeding period: Pre-feeding period is the transition period from young duck to cramming duck, which varies in length. If the ducklings are raised in grazing, the pre-feeding period should be slightly longer so that the ducks can gradually adapt to the feeding environment; if the ducklings are raised in captivity, the pre-feeding period can be slightly shorter. The pre-feeding period is usually 3-7 days.

During the pre-feeding period, three things should be done: stop grazing and adopt captivity; feed all concentrates, mainly corn; a few days after the pre-feeding period, start adaptive feeding: generally fill 1-2 times a day, fill less, and make adaptive transition for formal filling.

Feeding period: the production of mule duck fat liver, feeding period is generally 2 weeks, up to 20 days, if extended, also can not fill up, indicating that the feeding process is improper, feeding failure.

Feeding frequency: 3 times per day and night as the basis, but not from beginning to end is 3 times to fill the bottom. Generally, the feeding period is divided into three stages: the first to fourth days are the initial feeding period, which is usually fed twice a day (once at 8:00 and once at 6:00), and the maximum is 3 times; the fifth to tenth days are the middle feeding period, which is fed 3 times a day (once at 8:00, once at 15:00 and once at 22:00), and the situation can be increased to 4 times in the next one or two days; and the 11th to 15th days are the late feeding period, which is fed 4 times a day (once at 7:00, once at 12:00, once at 17:00 and once at 22:00).

Feed amount: feed less at the beginning, and increase feed amount with feeding times after snail duck adapts. In general, at the beginning of feeding, about 400 grams of corn (measured by dry corn) per feather per day, increased to 700-800 grams in the middle stage, and increased to 900-1000 grams in the later stage. During the whole feeding period, each duck consumed about 14-17 kg of feed.
