Technical points for raising the survival rate of goslings

1. Preparation of brooding house. Two weeks before hatching, the brooding room should be rinsed, the ground and walls should be disinfected with 10% fresh lime water, and the utensils should be washed with 2% caustic soda, and the troughs, drinking fountains, lighting, insulation, exhaust, etc. should be prepared. .

2, select the goose seedlings. The quality of goslings has a direct impact on the survival rate and growth of goslings. Goose seedlings should be selected from the offspring of goslings injected with a small goose plague vaccine. The method of selecting goslings can be summarized as "seeing two touches". A look is to see the gosling's mental state, fluff color. The second touch is to hold the goose's neck and chest in one hand, touch the tail from back to back in the other hand, check whether the abdomen is enlarged, and observe the reaction when grasping touch. When selecting seedlings, the following nesting standards can be used to identify: 1 ​​The body weight meets the requirements of the variety, the group is neat; 2 The navel is covered by the abdominal villi, tight and dry; 3 The abdomen is broad and flat, the egg yolk absorbs well; 4 The feather is clean and shiny; 5 Full of vitality, good spirit, and responsiveness; 6 grip in the hand is flexible, struggling and powerful.

3, transport goslings to prevent the cold wind and hot high temperature. In early spring, due to the cold weather, goslings should be transported with enclosed vehicles. However, goslings should not be overloaded in the hatching box. When the temperature is high, the windows can be opened, but the wind cannot be blown directly to the goslings. In the hot summer, it is advisable to use open box cars or transport in the evening. After long-distance transportation or when there is high temperature and insufficient drinking water, goslings are prone to dehydration. Determine the dehydration method of goslings: You can first use a few goslings to do drinking test, such as drinking water after 10-15 minutes after the neck back, fall to the back, legs twitching phenomenon, indicating that dehydration. At this time, emergency measures should be taken to increase the room temperature to 30-32°C. Use 0.9% salt water to incinerate the leaves, and then put the dehydrated goslings on the plastic film sprinkled with the leaves. Follow the food and treat all the young people. After the goose is full, feed it in the trough and eat it before drinking.

4, timely drinking and eating. 24 hours after hatching, when most of the goslings have started to peck or pose, they should supply water and feed them, and then feed them after drinking. Drink 0.02% potassium permanganate solution for the first time, first dip the mouth of the gosling into water and allow it to drink for 3-5 minutes to meet its water needs, stimulate appetite, and promote meconium discharge. Later development is beneficial. It is best to supply warm boiled water within a few days. Goslings within 3 days of age should be fed with boiled water or cooked to eight ripe millet, broken rice, or cornmeal, and add egg yolk to their diet, plus one egg yolk for every 10 goslings. Food requirements are not sticky and stay loose. Feed 6-8 times a day (twice at night). Gradually transition from feeding cooked food to feeding raw food. Do not change it suddenly. From the 4th day of age, some green feeds can be fed. To prevent goslings from picking green food, they can feed the concentrate and then feed the green material. The goslings aged from 11 to 20 days are mainly fed with green and blue feed. The concentrate accounts for 20-30% of the diet. With the increase of the age and the increase of the body's capacity, goslings can be grazing. When feeding in large groups, individuals with weak constitutions and slow development should be fed in groups in a timely manner, give some fine material, good materials, and carefully nurse them. After the growth has been caught, they can be fed in groups.

5, pay attention to reasonable feeding. Goslings have small digestive tract volumes, poor digestion, and require fresh feed and easy digestion. If there is no full-priced feed, the concentrate can be replaced with rice, broken rice, or cornmeal. Green feed can feed lettuce leaves, cabbage leaves, and ryegrass. Before the broken rice is fed, soak it in water for 2-3 hours and drain it to feed. Before the green feed, leaves and rotten leaves should be removed and washed and cut into filaments. When feeding, pay attention to the amount of feed. Generally every 100 goslings have a daily feeding amount of 0.7 kg for green feed and 0.4 kg for fine material at 1-2 days of age; 2 kg for green feed and 0.7 kg for concentrate at 3-6 days of age. Feeding 3.5 kg of green feed and 2 kg of concentrate at 7-9 days of age; 7 kg of green feed and 3.5 kg of concentrate at the age of 10-15 days, gradually increasing thereafter. Do not feed dry material to prevent the geese from bloating after drinking enough water because of thirst.

6, pay attention to heat and moisture. Goslings have a weak ability to regulate body temperature, and they should strictly control the temperature and humidity during feeding. The duration of the incubation period varies depending on the species, temperature, age, and the gosling's strength, and generally requires two to three weeks of incubation. Suitable brooding temperatures are 28-27°C for 1-5 days, 26-25°C for 6-10 days, 24-22°C for 11-15 days, 22-20°C for 16-20 days, 20 After age 18 °C. Whether the temperature is appropriate or not can be observed by observing the performance of goslings. Goslings crowded into piles and did not eat, indicating that they were cold and the temperature was low. At this time, in addition to warming, they also used hands to disperse goslings to make them active. Prevent being squeezed to death. Such as young goose mouth breathing, cry loud and short, increase the amount of drinking water, indicating that the heat, the temperature is high, should increase drinking water, timely and appropriate cooling. Such as the young goose stretching legs, three or five in groups, quietly lying or drinking water regularly, excretion of feces, interval 10-15 minutes to exercise once, is a concrete manifestation of appropriate temperature. The humidity of the goose house is also important for the health and growth of the goslings, and generally requires a relative humidity of 60-65%. Humidity is too high, temperature is low, goslings are susceptible to respiratory diseases and diarrhea; humidity is too high, temperature is too high, goslings are susceptible to “sweat”, appetite is reduced, and disease resistance is reduced. Therefore, when the goslings drink water (because the goose is a waterfowl, there are playing habits), so that the goslings do not enter the sink, the water does not change body, do not sprinkle water on the ground, keep the goose house dry. The grass or sawdust inside the goslings should be replaced once every 2-3 days.

7, the food tank specifications and feeding density should be appropriate. The troughs of different ages have different trough sizes. Generally, the trough lengths and widths of 1-7 days old goose are 90 cm, 7 cm, and 5 cm, respectively; the troughs of 7-30 days old goose are 90 cm in height, width and height. , 10 cm, 7 cm. The stocking density is determined according to the feeding conditions and methods. Generally, the number of goslings raised per square metre for goslings is 20-35 for 1-2 weeks, 15 for 3 weeks and 10-12 for 4 weeks. Decrease as the age increases, with 100 in each group.

8, timely grazing and launching. Grazing can increase the ability of goslings to adapt to the external environment, promote digestion and metabolism, promote physical fitness, increase health, reduce disease, increase survival rate, and at the same time save a lot of feed. Grazing should be based on the weather, the heat and the age of the goose. When it is warm, it can be grazing 5-6 days old, and when it is cold it must be grazing 15-20 days later. You can return to the brooding room 20-30 minutes before the first grazing, twice a day. When grazing should pay attention to the time from short to long, the distance from near to far, slowly drive away; feed before grazing from feeding to feed, so that they are accustomed to eating grass; late release early in the day when cool; goslings chest and abdomen When moulting, grazing should be done after the dew has dried to prevent diarrhea. The goslings are reared until the 4-week-old feathers grow. They should be allowed to swim in the water on sunny days, and gradually adapt to the water.

9, strengthen management, pay attention to disease prevention. Always keep the gossip clean and hygienic. Clean the site and replace the bedding. The feeding trough and drinking fountain should be cleaned every day. The utensils and geese must be regularly sterilized. There must be special guards at night, pay attention to whether the temperature is suitable and prevent the rats from harming. Gooses that had not been injected with gosling geese vaccine were given subcutaneous injections of 0.3-0.5 ml of anti-goose larvae at 1-3 days of age. At the age of 2 days, drugs such as sulphonamides or furans or oxytetracycline should be administered through drinking water and mixed materials. According to the instructions for use, the drug should be used for 3 days, twice daily, 10 days after discontinuation of treatment, and then for 3 days in order to prevent salmonella in goslings. Colibacillosis and fowl cholera.

For the treatment of diseases of the Digestive System:

Many symptoms can signal problems with the GI tract, including: abdominal pain, blood in the stool, bloating, constipation, diarrhea, heartburn, incontinence, nausea and vomiting and difficulty swallowing, according to the NIH.

Among the most widely known diseases of the digestive system is colon cancer. According to the Centers for Disease Control (CDC), 51,783 Americans died from colon cancer in 2011 (the most recent year for available data). Excluding skin cancers, colon and rectal cancer, or colorectal cancer, is the third most common cancer diagnosed in both men and women in the United States, according to the American Cancer Society.

Polyp growth and irregular cells, which may or may not be cancerous, are the most common development paths for colorectal cancers (also referred to as CRC), and can be detected during a routine colonoscopy, according to Dr. John Marks, a gastroenterologist affiliated with the Main Line Health health care system.

[The best news is that, if caught early enough, they can also be removed during the colonoscopy - eliminating the possibility that they grow further and become cancer," Marks said.

For those patients whose cancer has already spread, there are various minimally invasive surgical options that have extremely good prognoses. It is recommended that asymptomatic patients without a family history begin getting tested regularly between the ages 45 and 50, according to Marks. [Symptoms which may suggest that you need a colonoscopy at an earlier age include rectal bleeding and stool/bowel habit changes which last for more than a few days."

While CRC gets a great deal of attention, many diseases and conditions of the digestive system - including irritable bowel syndrome, diverticulitis, GERD (acid reflux) and Crohn`s disease - can be chronic and are difficult to diagnose and treat, according to Dr. Larry Good, a gastroenterologist affiliated with South Nassau Communities Hospital. [With many of these diseases, blood work and colonoscopies all looks normal, so there is an absence of red flags."

Many of the diseases of the digestive system are tied to the foods we eat, and a number of sufferers can reduce their symptoms by restricting their diets, Good said. [Of course no one wants to hear that they can`t eat certain foods, but many times, eliminating acidic things from the diet, such as tomatoes, onions, and red wine, can have an impact," Good said.

There are a number of tests to detect digestive tract ailments. A colonoscopy is the examination of the inside of the colon using a long, flexible, fiber-optic viewing instrument called a colonoscope, according the American Gastroenterological Association. Other testing procedures include upper GI endoscopy, capsule endoscopy, endoscopic retrograde cholangiopancreatography and endoscopic ultrasound.
