Langde goose breeding technology
Langde Goose, native to France, is a medium-sized goose with gray-brown feathers. Its down output is up to 350-450 grams and weighing 7 kg to 8 kg. It is the goose species most suitable for the production of goose livers, 70 days. Age can be sold as a commercial goose, 90-120 days old can get a variety of products. Langde goose is resistant to rough feeding and has strong adaptability. The survival rate of goslings is as high as 90%, the feeding period is short, and the quality of fatty liver is good. It is not available in other geese. Goslings are goslings within 30 days of age. The breeding of goslings is an important part of the production of goose. Its brooding techniques are as follows. 1. Brooding and Insulation There are two ways of brooding. Brooding is brooding by raising the young geese on a littered floor or brooding in a basket. On-line brooding involves brooding on a wire netting 50-60 cm above the ground. Goslings in the form of insulation, artificially divided into two kinds of artificial warm brooding. Artificial incubators can be used for incubators, underground flue fire protection or coal stoves. Since brooding, brooding baskets, barrels, or cartons can be used as brooding utensils, and the grass is draped in grass. The heat of the goslings can be kept within a small range without loss. 2. Feeding and Feeding of Goslings Feed for goslings includes concentrates, green feed, minerals, vitamins and additives. Freshly hatched goslings have poor digestion and need to feed some feeds that are digestible and rich in crude protein. Use mixed feed or soaked, slightly cooked millet. Within 1-3 days of hatching, the goslings must be allowed to drink and eat. Before the start of eating, goslings should be allowed to boil water, and the water dish filled with clean drinking water should be placed on the corner of the column. A part of the goslings' mouths should be pressed into the water dish several times to allow them to drink water. As long as there are individual goslings drinking water from the water tray, Other goslings will follow drinking water. Then put the chopped greens on the hands and shake them, or evenly spread the cooked parboiled or chopped greens on the straw mat or plastic cloth, gently beat the mats or plastic cloths by hand to lure and train the young Goose eats. After 2-3 days, feed tanks are gradually used for feeding. When large groups are raised, chopped green vegetables can also be fed freely in feed bowls. Goslings eat less in 1-3 days and feed 4-5 times a day. Times, which feed 1 at night. Later, the number and quantity of feedings will increase with age. At the age of 4-10 days, you can feed 6-8 times a day, including 2-3 feedings at night. When feeding green fodder every day, you can add appropriate amount of rice grains. Such as feeding mixed feed, the proportion of dietary mix is ​​60%-70% for green feed and 30%-40% for feed mix. Goats from 11 to 20 days of age should be dominated by blue-green material and fed with rice to over-ground rice. For example, when feeding compound feed, the proportion of diets is 80%-90% for green feed, 10%-20% for concentrated feed, and 6 feeds per day, including 2 nights. If the weather is mild, you can start training grazing. At the age of 21-30 days, the diet can be properly added to boiled grains and gradually added to the wet cereal. When bred in the house, the proportion of rations is 90%-92% for green feed and 8%-10% for concentrates. Feed 5 times a day, 1-2 times in the evening. Goslings should pay attention to the following five items: First, feed for goslings, especially green feed, must be fresh and clean. Second, feeding should be done regularly and quantitatively. Third, we must ensure that there is sufficient clean drinking water. Fourth, feed conversion should be carried out gradually, from soft to hard, from soft to hard, from feeding to grazing to gradually transition. Fifth, 1%-2.3% bone meal, 1% shell powder, and 0.25%-0.3% salt should be given to the diet. 3. Management of goslings (1) Insulation. The optimum growth temperature for goslings is around 25°C. The temperature required for the brooding period can be adjusted according to the age and the weight status of the goslings. The 1-5 day old brooding temperature is 27-28°C, relative humidity 60%-65%, room temperature 15-18°C, 6-10 days, brooding temperature 25-26°C, relative humidity 60%-65%; 11- 15-day brooding temperature is 22-24%, relative humidity 65%-70%, room temperature 15°C; 16-20 days brooding temperature is 18-22°C, relative humidity 65%-70%, room temperature 15°C; 16- The 20-day-old brooding temperature was 18-22°C, relative humidity 65%-70%, room temperature 15°C. The incubation period of goslings is 20-30 days, and timely de-warming can enhance the geese's constitution. (2) Density. From the time of brooding, the breeding density is usually 22-25/m2 for 1-5 days, 20/m2 for 6-10 days, and 12/m2 for 16-20 days. When brooding with a stove or ground plume, 15-20 birds per square meter at 1-10 days; 10-15 birds per square meter at 11-20 H; 5-10 birds per square meter at 21-30 days; 31 - 60 days old 4-5/m2; 60 days old 2-3/m2. (3) Grazing. Goslings can gradually start grazing on the 7th day of age. The north can grazing in the sunny place after 15-20 days of age. The grazing should be selected in sunny weather. The temperature should not be lower than 15°C, and the dew should evaporate and then released after 20-30 days of age. Grazing can be done all day. 4. Gosling disease prevention and treatment 1 - 7 days old use of norfloxacin and other antibacterial drugs to prevent bacterial infection, drinking water to add a variety of vitamins, especially vitamin C and vitamin E, once every 3 days, conditions to add some diuretics. 15-18 days old intramuscular injection of gosling plague vaccine.
