Goose rearing should be carefully prepared according to the different age of the goose, and the green material should be properly fed to meet the nutritional needs of the goose. So how long does it take for farmed commercial geese to be marketed for sale? How is feeding done? What are the technologies?
How long does it take for farmed commercial geese to be marketed for sale?
1. In meat livestock and poultry, from birth to market slaughter is a production cycle. The short production cycle of geese is inseparable from the rapid growth and development of geese in the early stage. According to studies, the time from birth weight to weight doubling for different bird species is 8-10 days for ducks, 12-15 days for chickens and turkeys, 6-8 days for geese, and geese for the shortest. 8-week-old geese can reach 80% of their annual weight, chickens are 60%, and turkeys can only reach 15%, still the goose is the fastest. The weight of small goose species in China is 2.5-3 kg at 60-70 days old; medium goose species can reach 3-4 kg at 70-80 days old; and large goose species can reach more than 5 kg in 90 days. The short production cycle shortens the time to input and output, accelerates the turnover of funds, and thus improves labor productivity and economic efficiency.
2.70-80 days old meat goose, after the end of stubble grazing, the feathers have been basically grown, at this time from the economic point of view, although it can be slaughtered and eaten or sold on the market, but after all, the goose at this time has not grown, the weight of life is small, and the fat is not enough. In order to further increase the meat yield and improve the meat quality, the fattening period can be extended for another 1-2 weeks, and the goose can be further fattened by feeding a large amount of concentrate every day, and then sold on the market.
How are commercial geese fed? What are the technologies?
1. Selected chicks:
Breeds with large size, fast growth and tolerance to rough feeding should be selected, such as white geese and gray geese. The chicks are required to be robust and responsive, the yolk contracts well, can stand firmly after the hair dry, makes a strong cry, and quickly contracts its feet when holding the neck with your hands. Weak chicks such as large abdomen and crooked heads should be eliminated.
2. Fine feeding of chicks:
The chicks just out of the shell are fed 0.05% potassium permanganate solution and add vitamin C5 ml, vitamin B16 ml, glucose 5 g, brown sugar 3 g for 5 consecutive days in every 100 min elevated potassium manganate solution. Use fresh lettuce leaves or fresh young vegetable leaves in a clean place to feed them, feed once every 2 hours; feed the rice blanks soaked in water at 2 days to 4 days old, feed them 4 to 5 times a day, 1 time at night; feed 7 to 8 times a day from 5 days old to 10 days old, 2 times at night, rice in the diet accounts for 20% to 30%, green feed accounts for 70% to 80%; 11 days old to 20 days old gradually feed compound feed, eat grass, feed 5 to 6 times a day, 2 times in the evening. The feed formula is (%): corn 50, fishmeal 8, peanut bran 10, rice bran 20, fine bran 10, auxin 1, shell powder 0.5, bone meal 0.5, plus antibiotics and multivitamins 0.5, salt 0.3.
3. Raise the goose:
When the goose grows to 4 weeks to 10 weeks old, it should leave the brood and transfer to the growing goose house. After the 30-day-old goose to eat the main green feed before the main wing feathers grow out, appropriately supplement the concentrate, so that it fully exercises and improves the vitality. Generally, it is fed 4 to 5 times a day, including 1 additional feeding in the evening. When feeding, the grass can be chopped and mixed with the concentrate and placed in the food trough, and the ratio of concentrate to pasture is 1:4, which is mixed into a semi-dry and semi-wet feeding. The concentrate can be used as a self-ingredient, and its formula (%) is: corn flour 45, rice bran 15, bran 10, soybean meal 22, fish meal 4, bone meal 1.5, shell powder 1.6, trace elements and vitamin additives 0.5, salt 0.4; or corn 20, fishmeal 4, peanut bran 4, rice bran 10, fine bran 60, auxin and antibiotics 1, shell powder 1. The amount of compound should increase day by day with the age of feeding, and the pasture can be cut into 1 cm to 2 cm long to feed the geese. If there is no water sports field, the water dispenser should be continuously cleaned and cleaned twice a day. Grow the goose house clean once a day, change the pad grass frequently, in case of sunny days, you can add grass on the sports field, add it after eating, keep the environment clean, hygienic and safe, and let the geese grow fully.
4. Rapid fattening:
After 40 to 50 days of rearing, the main feathers of the goose have grown, and when the weight reaches 1.5 kg to 2 kg, the "high energy, low protein" diet can be used for intensity fattening for 20 to 30 days, and the weight of the goose can reach 4 kg.
