Muscovy ducks are known for their fast growth, rough feeding, easy fattening, high lean meat percentage, and delicious taste. At the same time, they have the advantages of good manure performance and less material consumption. They are considered to be the most promising productive fatty liver. One of the poultry species. According to some data, the largest fat liver after fattening can weigh up to 450 grams.
1 Determine the day of fattening and weight. Filling the age and weight of the fat is closely related to the liver-to-material ratio after fattening and the quality of fatty liver. According to the comparison of relevant experimental data, it was found that the newborn Muscovy ducklings were raised to 90 days of age, and the body weight of about 2.5 kg (male Muscovy duck 2.0 kg) began to be fattened. The best effect was to produce fatty liver. If Muscovy duck weight is too small, it will result in an increase in the number of disabled ducks, a small amount of fatty liver, and quality times; if it is too heavy, it will consume more material and cost more.
2 feed feed Muscovy feed to feed on starch-rich cereals and other energy-based feed, especially corn is the best, but corn contains less choline, it should be appropriate to feed some wheat feed. Yellow corn is better than white corn in corn, because the fatty liver produced by yellow corn is pure yellow; while the fatty liver produced by white corn is pink. The preparation method of the feed is: before filling, first soak the corn kernels with water and put them into boiling water for boiling for 5 to 10 minutes until the corn kernels are cooked and then remove them. Then add 1% to 5% vegetable oil or animal oil while still hot. (Lard oil may also be used), and 0.3% to 0.5% of salt, 0.1% of multivitamins, and appropriate amount of fine sand may be added in each feeding amount, and the mixture may be fully fed and then fed. When filling, it is required that the feed is neither cold nor hot and is not hot.
3 Filling method and feeding amount In the case of the same feed and filling age, the filling technology and the amount of filling material have a great influence on the weight and quality of the liver. Filling methods can be divided into two types: machine filling method and artificial feeding method. The artificial stuffing is generally used to hold the Muscovy duck on both knees with its head facing upwards to expose the neck. The left hand will open the duck bill, and the right hand will catch the food in the mouth to forcibly swallow it, repeatedly. The machine is fed with a cannula and inserted directly into the duck sac, which is then filled by a pipe machine. Feeding time is usually 2 to 3 weeks. Every day, the ducks are fed 2 to 3 times a day, and the 2 to 3 weeks are fed 2 times a day. The average amount of feed per duck increased from 150 to 250 grams each time; the number of females increased from 100 grams to 250 grams each time. The average weight gain during the 3 weeks of feeding is 50% to 70%. Muscovy ducks can reach an average of 350 grams.
4 Correct management during the feeding period The breeding density during filling is preferably 3 to 6 per square meter, 30 per small group. It is best to combine the net and captives to limit their free activities and prevent them from splashing. Feeding should be done gently. With prolonged feeding, increased fat deposition, hepatic hypertrophy, prone to indigestion, can be fed 1 piece of lactase biofilm. In addition, we must maintain adequate drinking water and provide good sanitation.
(5) Extraction and processing of fatty liver The liver is crisp and tender and easy to crack. Removal and processing must be taken seriously. It is best to slaughter and processing on the spot, even if it is transported outside, we must lightly catch it in order to avoid damaging the liver and affecting the passing rate of fatty liver. The duck carotid artery should be accurately cut during slaughter. The bleeding must be thoroughly performed. Afterwards, scalding with warm boiled water at 65°C to 75°C, the net carcass should be stored at 10°C for 18 to 20 hours after the net hair is pulled out, and then the liver is opened for harvesting. Care must be taken when removing the gallbladder so as not to injure the fatty liver. The integrity of the fatty liver should be maintained as much as possible. The gallbladder should not be scratched so as not to affect the quality of the fatty liver. After the liver is removed, the liver can be washed with dilute saline, then wrapped with sterile gauze, placed according to weight, and not stacked. Can not be immediately dealt with can be frozen in -40 °C environment, and then stored in a cold storage at -20 °C.
