White goose body treasure scientific aquaculture benefits
China is the country with the largest number of meat geese in the world. Meat geese are mainly herbivorous, and they are characterized by low investment, low cost, short growing period, strong disease resistance, and easy feeding. They are favored by farmers. Due to the low natural breeding capacity of meat geese, many farmers have been worried about not having enough scale and not spending money. The market share of meat and geese at home and abroad has also been continuously increasing. Last year, the demand for meat geese in China was more than 1 billion, while the population of livestock was only 400 million. Therefore, the development of the meat goose breeding industry has a very promising market. Because of the low reproductive ability of meat gooses, which results in farmers not receiving enough returns, how can meat geese increase their reproductive ability? Scientific selection should pay attention to The selection of species should be based on local conditions. The geese required in different consumption areas are not the same. For example, Jiangsu and Zhejiang prefer white goose breeds, but Guangdong, Guangxi and Hong Kong prefer grey breeds and different goose species consumption. The price difference is very large, so it should be adapted to local conditions and choose the goose species according to the consumption characteristics of the market. The second is the hybrid method. If you like grey feather goose, you can collect the hybrid combination of gray feather goose for breeding; if you like white feather goose, you can use white feather goose for cross breeding. Goose geese must improve their aquaculture efficiency by selecting certain standards when selecting goslings, reserve geese and adult geese. This will help improve the production performance of geese. It is best to choose the 2-4 age geese to lay eggs to breed goslings, requiring strong physique, heavy head, lively action, eyes with flexibility, long and wide body, soft and elastic abdomen, long and dense hair. Get out of the shell prematurely or too late, the weight is too light, the big navel, the eyes are not god, gosling gosling do not choose. In addition, the geese were required to be immunized with a gosling vaccine. Reserve gooses reserved for species use, male geese require large size, strong physique, moderate fatness, moderate head, two eyes, thick armor, thick and slightly long neck, loud vocal, deep and wide chest, The abdomen is wide, the toes are thick, and the width is wide; the goose requires a long, round shape, well developed, moderate head, flexible eyes, slender neck, shallow forequarters, deep hindquarters, wide hips, and strong feet. , wide spacing. What time is good As the saying goes: "It is eaten by it, pulled by it, for sixty days, just to kill." It is the meat and geese slaughter time. In general, the growth and development of meat goose is divided into three stages. The body weight from hatching to 20 days is 10 times of the birth weight, but the ability to adapt to environmental changes and disease resistance is poor. This time is mainly to strengthen the feeding and management, improve the survival rate, and improve the quality of goslings. 20-40 days old are called middle-aged chicks, some also called young goose or young goose. Although the body weight is large, the pectoralis muscle is not thick, the slaughter rate is low, and the edible part is small. At 40-60 days of age, geese are known as people. They limit their physical development through means of husbandry and promote the accumulation of large amounts of fat in the body to increase body weight. At this time, goose quail meat is tender, delicious, slaughter rate is high, the edible part is more important. After 70 days of age, the geese start the first small moulting, greatly reducing the degree of weight loss, and lowering the slaughter rate. . Practice has proved that no matter what breed of geese, 20-60 days of age, the growth and development is relatively fast, the absolute increase in weight is high, and then decline with the increase of feeding age, thus the consumption of materials and costs will increase, it can be seen that the meat geese raised The 60-day sale has the highest economic benefits. Feed is a key factor influencing the weight gain of goose and the duration of the feeding period. In order to increase economic efficiency, during the period of 21-40 days when weight gain is relatively fast, physical cultivation of meat goose should be well grasped, and proper supplementation of concentrated feed can not be ignored. Every day must have a certain time to go out to grazing, release water, stretch the skeleton, enhance physical fitness. Big-framed geese have a good fattening effect and contain more meat. During the 41-60 days of age, the main focus is on fattening. The feed is mainly corn and potato, and it is best to boil the feed to a half-cooked state. According to the individual size, strong and weak geese were reared separately and fed 4-6 times a day, including 1 feeding at night. To feed carbohydrates rich in rice, bran, corn and other concentrates, after the geese finish the concentrate, they can feed a little green feed to help digestion. At the same time provide enough water to help digestion and metabolism. Keep geese in a quiet and dark environment and limit their activities to promote the deposition of body fat. Once the geese are found to be sagging in the abdomen, plump in the chest, plumage in the shape of a light body, rectangular shape, thickened subcutaneous fat, and a chestnut-sized, firm, elastic cellulite, the fattening can be stopped and sold for sale. After 60 days of fast fattening, the large geese can weigh up to 5.5-6 kg, the medium and small geese can reach 3-4 kg, and the edible part accounts for more than 60% of the carcass weight. Meat geese fast fattening support three strokes It is not feasible for meat geese to feed a single green grass. The efficiency of a single grass grazing geese is very low. The geese have a very slow speed. It is necessary to make the growth and development of meat geese better. How long the meat is, on the one hand, grazing is used to eat grass, on the other hand Must be supplemented with concentrated feed to meet the nutritional needs of the goose when it grows and develops. Filling geese is generally used to produce goose liver. In some European countries, especially in France, consumption of goose liver is a kind of food culture. It is about five to six hundred years old. The production of fatty liver generally allows animals to eat large amounts of concentrate, especially high-energy corn. Because of the high sugar content of corn, domestically produced goose livers are generally filled with corn. The medium goose or meat goose that is not used for breeding, after being short-term fattened for 15-20 days before going on the market, the fat is tender, the breast muscle is full, the taste is delicious, the slaughtering rate is high, and the benefit is significant. According to different regions and different farming conditions, the following methods can be used to rapidly fatten meat geese. Grazing fattening. In general, it is carried out in conjunction with agricultural time, that is, 50 to 60 days before the harvest of rice and wheat begins to raise young geese. When it grows to 50-60 days old, it coincides with the time of harvest and the grain and wheat grains left over from the harvested free space. Grass seed is the best goose. In order to improve the effect of grazing and fattening, the amount of meat geese should be reduced as much as possible. You can take a temporary goose shed, where the geese grazing, and where you stay overnight. This will not only reduce the time to run back and forth, increase the time for feeding, but also reduce energy. Consumption, promote fattening. Grazing and fattening must be done in order to ensure that there are not only abundant food sources but also rivers with clean water along the grazing land. After about 10-15 days of grazing, you can fatten the slaughter. This kind of fattening method has the lowest cost. Upper shed fattening. A bamboo scaffolding made of bamboo or wood is used. The bottom is about 60-70 cm above the ground. Bamboo is attached to the perimeter of the scaffold. The troughs and sinks are hung outside the fence. The meat goose feeds its head between the two bamboo strips. And drinking water. In order to limit the activities of meat geese, scaffolds can be divided into several small columns, each column is suitable for 10 square meters, 4 per square meter. During the period of fattening, high-energy feed such as rice, minced rice, sweet potato, corn and rice bran is mainly used. Feed 3-4 times a day and a small amount of green material can be given after each feeding. Captive fattening. Use bamboo or straw to form a small bar with 5-6 per bar. The size of the bar should not exceed 2 times the area occupied by all geese. The height should be 60 cm. The meat goose can stand in the bar, but it can't be shouted. Frequent tweets are not conducive to fattening. Feeding tanks and drinking fountains are placed outside the bar. Goslings can extend their heads to eat and drink. They feed three times during the day and one at a time. Feeds are mainly corn, bran, bean cake and rice. In order to increase the appetite of geese, a proper water bath and sunbathing should be provided during the fattening period. The geese should be bathed in the pond once a day for another 10-20 minutes each time. Forced fattening. Forced fattening is commonly referred to as feeding and fattening. Feeds such as corn, wheat bran, ground rice, sorghum, and bean cake are used, mixed with water, and filled with about 5 cm in length. Manually fill in goose esophagus and force it to swallow. Begin filling 3 times a day, each time filling 3-4, then increase to fill 5 times a day, each time filling 5-6, after 20 days weight gain can be more than 1 times. How can goose feathers sell for a good price The production of down products requires a large amount of goose feathers. How to make the goose feathers of meat goose breeders sell at a good price, so as to maximize the benefits, live goose plucking and live goose plucking are a good choice. Live geese plucking and live plucking are the same concepts and different expressions. It is based on the biological characteristics of natural moulting and feather regeneration capabilities of birds and the use of artificial techniques to extract live geese and down velvet. It meets the physiological characteristics of geese and scientific farming practices. . Live-pull down has changed the habit of pulling hair once after the slaughter, and the hot-pulled velvet has a high temperature of water, destroys some of the fluff, reduces the elasticity of the fleece, and has a higher bulkiness and containing more fluff than the cashmere. high. The use of artificially live down feather not only increases the down output, but also increases the down quality and greatly improves the production efficiency. Live plucking is a major reform in feather production. Goose feathers unwound by live geese plucking technology are dry, have few impurities and are high in content. A white goose weighing 4 kg can be plucking 6-8 times a year, about 100 grams each time, with an annual output of about 1 kilogram of hair, and a net income of 40 yuan or more. In general, flesh geese can begin to plucking after 60 days of hatching and then pull hair every 35 days and up to 40 days. Pulling wool with eggs or geese will reduce egg production. However, when the egg production period is about to elapse, egg production is significantly reduced, and gooses that are ready to be eliminated can be used for wool collection. In general, a goose can pull three consecutive years of hair, and later it will be eliminated. Magical use of foie gras Foie Gras is the liver of the geese of the family Anatidae. The liver is an important organ for storing nutrients and detoxification in animals. It is rich in nutrients and has nutritive and health functions. It is one of the most ideal blood products. Foie Gras has become unusually expensive due to French Western food. Its rich nutrition and special effects make it the best food for blood and health. Goose fat liver is hailed as "the king of food in the world" and is one of the world's most precious nutritional foods. Goose liver is rich in carbohydrates, protein, fat, cholesterol and iron, zinc, copper, potassium, phosphorus, sodium and other minerals, and has the effect of nourishing blood. Goose fatty liver is a fatty liver that is cultivated in living geese. This fatty liver has a delicate texture and delicious taste. It is respected by European and American people as the world's top three delicacies, namely goose liver, matsutake mushroom and salmon roe. Goose liver fat content of 60%, the vast majority of unsaturated fatty acids, rich in copper, triacylglycerols, lecithin, DNA and RNA, has a high medicinal value, can increase the body's enzyme activity, It regulates calcium and phosphorus metabolism, lowers blood cholesterol levels, softens blood vessels, and prevents cardiovascular diseases. Most people can eat, acute and chronic cholecystitis, cholelithiasis patients do not eat, each 20-30 grams. Foie gras is a high-cholesterol food. Disorders of cholesterol metabolism are one of the reasons for the formation of gallstones. They should eat high cholesterol foods. Excessive consumption of foie gras can increase the risk of arteriosclerosis and coronary heart disease. Some of the toxins and vitamin A levels in the liver are high. If you eat too much at a time, it can cause acute vitamin A poisoning. Liver foods are high in cholesterol, but they are good for the eyes. Goose liver with congestion, lumps, or parasites must not be eaten. Must be thoroughly soaked in water for 3-4 hours before consumption to eliminate toxins. Heat enough to not eat half-life, bloody foie gras. According to expert confirmation, the general foie gras contains only 2% to 3% fat, while the goose liver fat content can be as high as about 60%, but the goose fatty liver is mainly unsaturated fat, easy for the body to absorb and use, and after eating Will not gain weight, but also reduce the level of cholesterol in human blood, and its invisible lecithin, which is indispensable for human life, is much higher than normal foie gras. Goose liver is also rich in fat and sweet "glutamic acid", so when heated there is a particularly attractive fragrance, this kind of fragrance is indescribable, only in the body to know its wonderful where, and when heated to 35 °C The fat begins to melt, and it is also close to the temperature of the human body, so there is a feeling of entrance.
