Bream farming has ways to increase egg production

Editor's note: wolfberry has a high food value, is a typical high-protein, low-fat, low-cholesterol food for middle-aged and elderly people, high blood pressure, obesity patients; quail eggs is also a good tonic, in nutrition There is something unique about it, which is called "Original Quality". In this issue, we will introduce a group of artificial breeding techniques and hope to provide assistance for farmers to grow rich.

Egg preservation

When the egg temperature is at a suitable temperature, the embryo development stops temporarily. Then, the embryo develops again under certain external environment. When the ambient temperature is high, but not the suitable temperature for embryonic development, the embryonic development is incomplete and unstable. It is easy to cause early embryonic death when the ambient temperature is low for long periods (0°C). Although the embryonic development is at rest, the vitality of the embryo is severely reduced and even died. Normal egg preservation temperature is 13 °C ~ 18 °C, save a long time, using the lower temperature limit, save time is short, the upper temperature limit.

There are approximately 7,500 pores with a diameter of 1.5 to 15 microns on the shell of the relative humidity eggshell. During the preservation of the eggs, the moisture in the eggs continuously evaporates through these pores, which is inversely proportional to the stored humidity. The relative humidity is usually kept at 75% to 80%. In addition, do not allow direct sunlight and direct draft through the draft.

Preservation time Even if eggs are kept in a suitable environment, the hatching rate will decrease with time. With the extension of storage time, the bactericidal properties of the protein decreased. The evaporation of water in the egg increases, changing the pH in the egg, causing the yolk and yolk membrane to become brittle. Due to the activity of various enzymes in the egg, it causes embryonic degeneration and degeneration of nutrients, reduces embryonic viability, and reproduces residual bacteria. Embryos are endangered, leading to a drop in hatching rate. It is generally considered that the preservation time of eggs is 5-7 days, and it should not exceed 2 weeks.

Preparing for brooding

Sanitizing and repairing the brooding room, the best conditions for the best vacancies for 15 days, so that insulation, heat insulation, ventilation, full cleaning inside and outside, all around the walls, floors, food troughs, drinking fountains and cradle with 3% hot caustic soda solution Spray disinfection, completely kill all kinds of pathogenic microorganisms. After 2 hours, rinse off with clean water, install insulation equipment, seal, and sanitize with 28 liters of formalin and 14 grams of potassium permanganate per square meter for 24 hours. The temperature during fumigation is preferably controlled at more than 20°C and the humidity is 75%. Open the doors and windows to vent the odor, and then close the vacant for 5 to 7 days. The birdhouse was cleaned every day for 1 week and cleaned and disinfected once a day. After 7 days of age, the birdhouse was used 3 to 4 times a week. During the brooding period, it is necessary to insist on disinfecting the birds every day Ultraviolet lamps or disinfection tanks are set at the entrance of the brooding room. It is better for the breeder to not leave the brooding room during the brooding period, and the entrance and exit must be strictly disinfected.

Choosing a healthy youngster first chooses a variety of plants that have a good reputation, a strict epidemic prevention system, and a high hatching rate. The healthy seedlings are sturdy and strong. They have strong, elastic and lively spirits. They have bright eyes and no secretions. The hairs are plump and clean with bright colors and the body weight is in line with the standards. The umbilicus mouth is closed and clean without blood marks, and the cloaca around the feathers is clean without feces.

The correct pick-up shall be carried out for the complete disinfection and inspection of transport vehicles. The transport tools shall be windproof, breathable, and not heat-insulated. The density of the chicks should be determined according to the seasonal climate. The darker the light in the truck, the better. Keep the chicks quiet, avoid physical exhaustion, and indulge in feces and other contaminants. It is best not to stay in transit, especially in the early spring season to prevent heavy insulation and light ventilation and cause suffocation and death. The transportation time is preferably within 36 hours from the hatch, and the long distance should not exceed 48 hours.

Disease prevention and control measures

During the period of disease prevention and brooding, segregation work shall be done well, closed management, special personnel feeding, keeping the environment clean and regularly disinfected to ensure the hygiene of feed water. In order to prevent white lice 3 days before hatching, use Pulsatilla saponariae, niacin and nifedipine and other spices and drinking water, and pay attention to the prevention of coccidiosis 10 days later. There are sulfachloropyrazine sodium soluble powder or sulfaquinoxime sodium. Different anticoccidial drugs should be selected according to different regions, different coccidia species, different periods or seasons. In order to reduce the stress caused by vaccination, a certain amount of vitamin C and electrolytic cubes can be added to drinking water.

Addition of nutritive additives can be multi-dimensional, electrolytes, amino acids and glucose made of composite preparations. This type of product is mainly supplemented with energy, electrolytes, and amino acids for chicks, so as to alleviate the adverse effects such as long-distance transportation and high-temperature stress and prevent dehydration of chicks.

The purpose of choosing antibiotics for the use of antibiotics is to purify the gut of E. coli and salmonella in the intestine, prevent the occurrence of ferrets and omphalitis, and increase the survival rate. "Little chick nurse (complex compound of norfloxacin nicotinic solubilized powder) + Chica (orally amikacin sulfate)" may be used as a fledgling bird medicine.

The use of micro-ecological preparations in the market is not a lot, is a relatively high-end fledgling opener, its advantages are higher absorption rate, more suitable for the characteristics of digestion and absorption of chicks, to improve the intestinal flora.

Brooding management

Reasonable light illumination is an indispensable condition for the growth and development of the young chicks. Reasonable light intensity and light time can stimulate appetite, promote growth and reproductive function development, and unreasonable light can disturb its development. The specific illumination time was from 0 to 3 days of 23 to 24 hours, and it decreased from the 4th day of the week by 1.5 to 2 hours per week. Natural light was used after 3 weeks. In addition, we must pay attention to the light intensity, the previous use of 40 to 60 watt bulbs, 3 watts per square meter, late with a 25-watt bulb, 1 watt per square meter. According to the bird's green and yellow habits, the use of green light and yellow light is better than white light brooding and can also reduce the occurrence of deafness and anal habits.

Ventilation and ventilation In order to eliminate indoor air pollution and replace fresh air, ventilation should be performed and the indoor temperature and humidity should be adjusted. The protozoa have high body temperature, fast breathing and strong metabolism, and produce a large amount of carbon dioxide. In addition, about 20% to 25% of the protein in the diet of the proficient chicks is not digested, is excreted in the feces and fermented under high temperature and high humidity to produce large amounts of ammonia and Hydrogen sulfide. There is also carbon monoxide produced by the fire. If these toxic gases are not discharged in time, it will seriously affect the growth and development of the chicks and induce various diseases. However, to prevent thieves and cold winds from blowing, especially in winter, place heat sources at the air inlet to preheat the cold air.

Opened food and drinking chicks can be eaten 24 hours after hatching, preferably no more than 36 hours. First drink water, add anti-stress drugs and antibiotics in the water, first drink with 0.01% potassium permanganate, then add multi-dimensional electrolytes. The long-term transport of chicks is best to drink boiled water, the formula is to add 1000 ml of cold water, sodium chloride 3.5 grams, 2.5 grams of sodium bicarbonate, 1.5 grams of potassium chloride and glucose 20 grams. Feeding can be done within 2 hours after the first drinking, because the meconium of the young bird has been drained and there is hunger. 0 to 3 days of age were fed with corn grits to reduce the prolapse of the anal worm and the 3rd day of age gradually transitioned to the feeding of the protien concentrate. During the brooding period, it is advisable to feed less frequently, generally 8 times a day for the first 2 weeks, 6 times a day for the 2nd to 3rd weeks, 6 times for the 5th week, and 4 times a day for 6 weeks.

Increase egg production rate

The rate of egg production is closely related to the quality of feeding and management. It has certain requirements for environmental conditions such as feed, temperature, humidity, and light. The quality of eggs is also a determinant of the egg production rate. The production of meat or egg pupa is different. The broiled meat and egg pupa have higher egg production than pure quail broilers. Generally, the egg production rate can be increased by 15% to 20%. It is necessary to breed hybrid quail or egg tarts.

The crickets are raised in the wild, and although they have been domesticated by humans, they still maintain their wild habits, such as being timid, frightened, and afraid of sound and noise. Therefore, in order to make oysters more eggs, in addition to the need to create a quiet and appropriate breeding and management environment for quail, the following points should be made:

First of all, we must raise the embarrassment of the year. Pay attention to individuals who are strong and have strong appetite. The lifespan of crickets is generally 2 years. The hatching female quail eggs begin to lay eggs 35 to 45 days. After the eggs are laid for 8 to 10 months, their egg production drops. Therefore, if the amount of eggs produced after breeding for more than one year is reduced, the female quail that has been producing eggs for more than one year should be eliminated as soon as possible and sold for consumption after fattening.

Second, we must supply enough quality feed. After the mother quail begins to lay eggs, her appetite is strong, and crude protein should generally account for about 28% of the feed. More than 300 eggs are produced in 1 year, and calcium and phosphorus are consumed in large quantities. Attention should be paid to supplemental supply of calcium and phosphorus in the diet. Therefore, formula feed should be fed with as little or no grain as possible. General formulated feeds consisted of corn, 48%, cakes, 33%, light fish meal, 6%, hay powder, 5%, shell powder, 5%, bone meal, 3%, and a variety of vitamin additives, 0.3%.

Egg laying mothers have certain requirements for temperature and humidity. If the ambient temperature is lower than 15°C, the egg production will obviously decrease or even stop egg production. The appropriate temperature should be maintained at 18°C～25°C. The appropriate room humidity should be controlled between 50% and 60%, and keep enough clean drinking water.
