Analysis on the management technical points and precautions of fish goose polyculture
Today, Huinong.com has compiled a study on the technology of fish and goose polyculture. There are two problems in the implementation of the fish goose polyculture model. One is the problem of living water and the other is feed feeding. Let's get to know it together.
First, technical points
The three-dimensional culture of fish and geese effectively utilizes the water space. In the pond, algae, water plants and other aquatic organisms can be used for goose feeding. Goose has a lot of nutrients in the feces, is a bait for omnivorous fish, and is a good fertilizer for pond plankton. If the geese are scattered into the pond, the microbes are decomposed for fish to eat, which not only saves the feed, but also reduces the cost of breeding. It is estimated that one geese can produce 5 kilograms of fish. When fish and goose are mixed, the farmers do not need to worry about the lack of oxygen caused by the weather changes, because the general breeding domesticated geese have physiological conditioning for low pressure. Once they encounter climate change, they will rush into the water and bathe in the pool. Play and play, causing the water to tumbling, and the oxygenation effect on the fish pond is particularly good. The use of geese to play water to increase oxygen does not have to worry about the interruption of oxygenation caused by power outages, and there is no need to worry about major losses such as accidents caused by electric leakage.
(1) Tangkou selection
Tangkou should be of appropriate size, too small water quality regulation function, affecting the growth of fish; too large for fish feed, geese stocking and water disinfection and water change are not good. Generally, the depth of the pond is more than 1.5 meters.
(2) Goose species selection
Generally, meat goose, egg goose, and egg-and-meal type goose species can be selected as the cultured species.
(3) Fish selection
It is mainly composed of scorpion, scorpion, scorpion, scorpion and other miscellaneous, filter-feeding fish, and adopts grass, green and squid.
(4) Stocking density and specifications
1. Stocking of geese: 50~120 geese per mu of water, choose good varieties or optimize hybrid combinations. Spring and summer are mainly beef geese and autumn geese.
2. Fish stocking: The main fish stocking specification is 50~70g/tail, and the total stocking amount per mu is 50~75kg. Winter is required, and summer flowers are properly raised in the medium term. Under normal circumstances, carp and carp account for 45%, carp and carp account for 50%, and grass and carp can account for 5%, depending on Tangkou conditions and management conditions. Fish species should be immersed in 2.5%~4% saline solution and disinfected.
(5) Feeding management
Goose feeding management
(1) Brooding management: The brooding period of the goose refers to the period from the shelling to the age of 4 weeks.
Drinking water early: It is also called boiling water. It is usually carried out 24 to 36 hours after shelling. The water temperature in winter is kept at around 25 °C. Multivitamins are added to the drinking water of goslings in 3 days. Water can not be cut off in the geese after boiling water.
Eat at the right time: The first time the gosling eats food, it is usually fed after boiling water. Use half-cooked rice or soaked broken rice.
Feeding times and methods: The brooding stage should be based on the principle of feeding less meals. 6 times a day for 3 days, 8 times for 4 to 10 days, 6 times for 11 to 20 days, and 4 times for 20 days. Within 10 days of age, the ratio of concentrate to green material is 1:2. After feeding the concentrate, feed the green material; after 10 days of age, the proportion of green material is gradually increased. Feed the concentrate after feeding the green material.
Grazing management: Spring brooding can begin to graze from the 5th day of age; in the winter, it will be grazing when it is 21 days old. Grazing should choose sunny and windless weather, while ensuring that the material and water are clean.
Insulation and moisture protection: Temperature is an important part of gosling management. When just coming out of the incubator, the temperature of the brooding room should reach 27~28 °C. With the increase of age, it can be lowered by 2 °C every 5 days, and the room temperature can be kept 15~18 °C after 3 weeks of age. At the same time, pay attention to ventilation and keep the house dry and clean.
Density: Goslings grow fast, and must always pay attention to adjust the density, 30/m2 in the first week, 8~10/m2 in the second week, and 6~8/m2 in the third week.
(2) Breeding house and activity field: The geese house should be built according to 6/m2 in the field at the north side of Tangkou. The goose house is watertight and moisture-proof. There is a drainage ditch in the house. There is a drinking fountain on the house. The activity building is built according to 3~4 square meters for the goose activity and feeding. The ground of the activity field is flat, slightly inclined to the water surface, and a suitable area of ​​the awning is built. The egg laying box should be arranged in the farmed egg geese, placed in the light around the wall, keeping the material in the box soft to reduce the ground laying.
(3) Daily management: scientific management of different living habits and growth patterns of meat goose, egg goose and dual-use goose. First, keep the geese house well ventilated, clean and monotonous, change the bedding, and graze the goose group activities and swimming in a timely manner; second, rationally mix the geese feed (to use the full price), and maintain the feed diet relatively consolidated, do not just Change, so as not to affect the digestion, absorption and growth of the flock. Daily feeding should be regular, quantitative, qualitative, and maintain drinking water; Third, the implementation of strict anti-epidemic measures, timely injection of various vaccines, found that sick goose timely isolation and elimination, feeding control drugs; Fourth, pay attention to weather, animal and pesticides Fertilizer poisoning.
2. Feeding management of fish
Water quality in Tangkou: Water is the living environment of fish. The quality of water directly affects the growth of fish, the occurrence of fish disease and the level of fish production. Therefore, water quality management is of vital importance. Requirements: The dissolved oxygen in the pool water is not less than 5 mg / liter, the carbon dioxide content is less than 30 mg / liter, the ammonia is controlled below 0.05 mg / liter, the oxygen consumption of organic matter is maintained at 25 - 35 mg / liter, and the pH is 7.0 ~ 8.5. The transparency of the pool water is 20~40 cm, and the plankton biomass is controlled at 70-150 mg/L. Fish goose polyculture pond water is easy to deteriorate, usually should be added water, change the water, the high temperature season from June to September should increase the number of water additions, preferably once a day, each time not less than 20 ~ 30 cm, and prevent hypoxia The occurrence of fish floating head and pan-tang phenomenon. In the summer, combined with fish disease prevention and control, 20 mg per cubic meter of lime is used for water quality adjustment to ensure that the pond water is “fat, live, tender and coolâ€.
Feed feeding: Generally, it is not necessary to feed the bait. In the main growing season and the pre-marketing period, the feed can be properly fed.
Fish disease prevention: 1PPM (parts per million) bleach solution is sprayed every half month from June to September to prevent disease. In mid-July, parasites were killed with 0.5 PPM crystal trichlorfon.
Second, the application prospects
(1) Input
Taking 3000 geese in the year as an example, 3 batches can be raised in one year, and each batch is 1000. The water surface area needs to be about 10 mu, and about 500 kg of fry can be placed.
1. Seedling input: geese seedling 3000 × 7 yuan / only = 21,000 yuan; fry 500 kg × 12 yuan / kg = 0.6 million.

2. The fish market has a total weight of 15,000 kg, the price is 5 yuan / kg, and the income is 75,000 yuan.
(3) Income
Except for input, the annual income of fish goose polyculture can be 156,500 yuan.
Third, promotion case
In 2013, Jiangsu Agriculture and Animal Husbandry Science and Technology Vocational College cooperated with Binhai County Haohan White Goose Professional Cooperative to carry out the fish goose polyculture model in Zhenghong Town, Binhai County. Practice has proved that the development of fish goose polyculture is more effective than single goose. Increased by more than 30%. At present, the total annual breeding of cooperatives is 1.356 million, and the annual hatching geese are 1 million. The annual output value is more than 20 million yuan and the net profit is more than 4 million yuan.
Regarding the technical points of the fish goose polyculture mode, today, Hui Nong.com has brought so many people to you. Interested friends can refer to the reference!
Plant extracts refer to substances extracted or processed from plants (all or a part of plants) using appropriate solvents or methods, and can be used in the pharmaceutical industry, food industry, daily chemical industry and other industries.
There is a conceptual overlap between plant extracts and herbal extracts. The raw materials of plant extracts in my country are mainly derived from Chinese herbal medicines, so domestic plant extracts can also be called Chinese medicine extracts to some extent.
