(1) Brooding conditions: In the feeding and management of young ostriches, we must first meet the brooding conditions, and we must mainly grasp the appropriate temperature, humidity, ventilation, and suitable breeding density.
1 Adjust the appropriate temperature, humidity: 1 week old chicks are extremely sensitive to temperature changes. When the ostrich chicks are warm on the back and cold on the abdomen, the yolks in the abdomen are poorly absorbed or not absorbed at all. This has greatly reduced the survival rate of young ostriches. In order to keep warm and protect the cold, the cages should be laid on the ground and the conditional winter can be used with electric heating plates or other insulation equipments to promote the absorption of yolk and make the flow of gastric juices and promote digestion. In the feeding and management process, it is necessary to observe the movement and status of young ostriches frequently and adjust the temperature with the normal state as the standard. For example, young ostriches are crowded together, appetite and energy are lacking, and quaking tremors are generated. This is a sign that the temperature is slightly lower. It should be warmed up. At the same time, young ostriches should be prevented from being suffocated and suffocated. If the young ostrich gasping for breath, drinking plenty of water, and spreading wings to heat, loss of appetite to refuse to eat, this is the performance of high temperature, use more water, less grass or remove insulation equipment and other measures to reduce the temperature. Suitable temperature in the brooding room: hatching young ostriches should be kept above 24Â°C within 2 weeks of age, and then gradually fall to 18Â°C; brooding chicks or brooding cages hatching hatchlings after 35 days (35Â°C) Room temperature is 25Â°C). It should reach 33-36Â°C within 1 week of age, 3Â°C every week from the second week, and drop 0.5Â°C every day after 1 month of age. Normally it will be defrosted after 2-3 months of age. From 1 to 4 weeks of age, when the weather is clear and high temperatures, young ostriches can be placed on the sports ground to enjoy the sun, and in the hot summer season, the sports ground should have shade or arbours in order to reduce the temperature in the brooding house.
In addition to adjusting the temperature required for brooding ostriches, the suitable humidity for brooding sheds, brooding and brooding cages is also very important. In particular, the change in demand for humidity during brooding and ostrich periods is greatly affected by the humidity of the embryos during the incubation period. If the humidity during the incubation period is low, dehydration may occur after the chicks have hatched and affect their survival rate. Humidity must be adjusted in time, such as measures to increase the humidity and supply nutrient solution. If the humidity during the incubation period is high, brooded ostrich edema occurs. The relative humidity in the brooding house is generally 50% to 55%. With the increase of the age of young ostriches, the ostrichâ€™s humidity requirements are not very strict and can be adapted within the range of 50% to 75%. However, the humidity during the rainy season should be properly reduced. The principle of grasping the humidity is that the humidity in the early brooding period should be lower than that in the later brooding period. The humidity in the rainy season should be lower than the humidity in the dry season.
2 Breeding density should be reasonable: to ensure that the young house has a certain space for the activity of young ostriches, in order to benefit the growth and development of young ostriches. According to the farmer's experience, the one-week-old chicks in the brooding house average an area of â€‹â€‹0.25 m2 each, and will be expanded by 10% per week thereafter. The average age of young ostriches at the age of three months is 2 m2, with the exception of the brooding houses. In addition, the area of â€‹â€‹sports grounds was gradually increased to 10m2 with an average of 5m2 each, and the size of the playing field was calculated. With the increase of the age of months, it is necessary to feed in groups to reduce the stocking density.
3 pay attention to ventilation and light: In the brooding room, when adjusting the temperature and humidity, we must pay attention to open the windows for ventilation, excrete the ammonia produced by bird urine in the house, in order to benefit the healthy growth of young ostriches. However, in the winter to avoid the wind, ventilation should be warmed up, avoid direct blow in the young ostrich body, so as not to catch a cold caused by the young ostrich cold. In addition, light has a great effect on the normal feeding, drinking, and activities of young ostriches. In particular, it can convert 7-dehydrocholesterol in the skin of young ostriches into vitamin D, thereby regulating the calcium and phosphorus metabolism of young ostriches and increasing the body's immunity. Strength and disease resistance. In order to make young ostriches see the sun in winter, the brooding house can be built into a glass greenhouse. In the summer sports field, trees or arbors should be planted to allow young ostriches to move and rest in the shade and prevent exposure to heat. Young ostriches of 1 to 2 months of age can be grouped into larger playground activities and habitats.
(2) Feeding and management methods: The yolk in the belly of newly hatched young ostriches can provide nutrients to maintain 2 to 3 days of life without feed. After 2 to 3 days, when the yolk nutrients are basically absorbed, the young ostriches can eat. Eating too early or too late affects growth and development. The young ostriches can feed the wet mixed concentrate after 1 to 2 hours after the first drink. After the start of eating, the mixed fine material can be mixed without wet mixing to prevent the long-term feeding of wet material and cause the indigestion of the young ostrich. Granules can be fed but not allowed to cause constipation or diarrhea.
The green-green feedstuffs that young chicks feed include quail, clover leaves, cabbage leaves, lettuce leaves, and carrots. However, the feed should be washed, dried, chopped and then fed. The chopped green and green stalks and the green feed containing residual pesticides should be banned. Feed 4 to 5 times daily. With the increase of the age of birds, the amount of feed for green feed should also be gradually increased. The amount of roughage for young ostriches up to 3 months can account for 40%, and the ostrich concentrate can still contain about 50% of grass powder, but it is necessary to prevent fine feed. Too much feeding causes the ostrich to gain too much weight and causes bones and joints to deform and develop leg problems. Since the feedstuffs eaten by ostriches can be grated in the muscles and stomachs, each ostrich bird is replenished with 4 to 5 insoluble grits washed and dried every 2 weeks after hatching. Young ostriches have a habit of eating anything. Therefore, in the feed, it is necessary to check for the incomprehensible substances such as broken glass, branches, iron nails, iron wire, and plastic sheet to prevent ingestion and digestion of the stomach before the ostrich swallows. Or a hard-to-treat disease such as stabbing inflammation. In the evening, because the young ostriches do not live and feed, they can not feed at night. In order to facilitate feeding and management, group rearing needs to be rearranged according to body size.
According to the fact that the yolk of the young ostrich has a relatively high water content (about 2/3) in the yolk of the abdomen 2 to 3 days after hatching, and as the young ostrichâ€™s breathing and urine excrement are consumed in the body, more water is needed. After 2 to 3 days of shell opening, drink water before eating, which can promote intestinal peristalsis, absorb residual yolk, eliminate meconium and increase appetite. Water requirements for the clean and warm water (water temperature is generally around 24 Â°C), conditional drinking water by adding glucose, B vitamins and vitamin H, electrolytes and other dubbed nutrient solution is better. The drinking water supply of young ostriches should be quantified regularly to prevent excessive drinking and wetting of the young ostriches and cause illness. According to the aquaculture experience data, the daily water supply is 1.8 to 2 times of the total feed intake.
The disease resistance of young ostriches is poor, and intensive feeding is more likely to infect and spread diseases. Mainly to do a good job of sanitation and disinfection. Every day should be cleaned of feces; debris, to maintain odor-free broiler house, and regular or irregular disinfection, wash and dry food, drinking utensils, litter, insulation equipment, insulation rooms use the right amount of potassium permanganate 15 ml / Meter 3 Formalin fumigation, sports venues can be used 2% to 3% caustic soda wet, after disinfection with fresh water showering the ground. Straw mats can be sterilized with sunlight exposure. In the breeding area, a disinfection pool or a disinfection basin was set up on the import and export, and 4% caustic soda was contained. At the same time, it is necessary to increase the management of young ostriches in accordance with the fixed-rate responsibilities to people. It is required to constantly observe and check the ostrichâ€™s spirit, appetite, excrement, behavior, etc., and find abnormal phenomena to isolate the treatment in time. The dead corpse of the epidemic disease was buried deep after soaking with disinfectant. At the end of the daily feeding and management work, a brooding record form should be filled out, and the status of the young ostriches found on the day of inspection and the main feeding and management work according to the growth stage, as well as the data, should be clearly recorded. From this, the healthy growth status of young ostriches can be known and summarized. Experience and evaluation The important basis for the careful and careful work of the husbandry and management personnel.
