1, the physiological characteristics of ducklings Ducklings have three main physiological characteristics. First, rapid growth and development, four weeks of age than the birth weight increased by 24 times, increased by 60 times at the age of seven weeks; Second, regulating body temperature is weak, it is difficult to adapt to the outside world, freshly hatched young ducks are small and delicate, villi few, insulation Poor ability, weak body temperature regulation; Third, small digestive organs, weak digestion, but fast growth, high feed conversion rate. 2. The preparation of brooding ducks should firstly prepare fresh and high-quality full-priced compound feeds and green materials; second, brooding rooms, playgrounds, feeding equipment and necessary facilities should be fully equipped to ensure that each duckling can eat feed and Drinking water. Once again, the brooding room, playground and feeding utensils should be sterilized with 20% caustic soda or 20% lime water, dried and rinsed with clean water. Finally, the brooding room should be equipped with cooling and temperature adjustment facilities. 3, ducklings must first drink water after eating ducklings, there is no hunger after hatching, no need to feed within 24 hours after hatching. After 24 hours, the young ducks have dry hair, lively and lively. They often make a buzz and start their activities. At this time, they must first feed water and eat. If the ducklings are mentally tired and their eyes are half-opened and half-closed, they are reluctant to exercise and this time has exceeded their open time. Ducklings eat too early, it is easy to damage the digestive organs, affecting the health of young ducklings; eat too late, the nutritional supply is not on, is not conducive to growth and development. Therefore, the best time for ducklings to eat is between 14 hours and 24 hours after hatching. Remember to eat before drinking. Adding a proper amount of glucose or vitamin C in drinking water can promote gastrointestinal motility, clear up the stomach, promote metabolism, accelerate the absorption of the remaining yolk, increase appetite, and enhance physical fitness. Therefore, it is necessary to drink water before eating. If you add 1/10000 potassium permanganate in drinking water, it can also play a role in gastrointestinal disinfection. 4, to feed the full-price pellet feed because the growth and development of ducklings is particularly fast, requires a lot of nutrients. After the ducklings start eating, they rely on feed intake to meet the nutrients needed for growth and development. Ducklings feed requires high protein and high energy feeds. The protein content in the diet should reach 20%-22%, supplemented with calcium, phosphorus and trace elements as well as various vitamins. If you only feed rice, due to monotonous nutrition, can not meet the growth and development of ducklings, prone to illness or death, feeding the full price feed can meet the various needs of duckling growth and development of nutrition. 5. Feeding methods for ducklings The ducklings have a short digestive tract, a small stomach muscle volume, and a poor digestive function. Therefore, when feeding ducklings, each should not be fed too much, only to feed sixty-seven percent full, if fed a full, easy to cause indigestion; ducklings gastrointestinal volume is small, and digestion speed is fast, if the number of feeding is small, Making the ducklings hungry for a long time will affect the growth and development of the ducklings. The ducklings within two weeks of age were able to reach the gastrointestinal tract within 5 minutes under free-feeding conditions, reach the duodenum in 20 minutes, defecate in 2 hours, and empty in 4 hours. Feeding time more than 4 hours, ducklings are hungry. In general, the younger the ducklings, the lower the food intake, the more frequently they are fed. In the early period of brooding (that is, within one week), it is necessary to feed less, feed more ingredients, feed 6-8 times a day, and feed a night meal 1 to 2 times to promote duckling activity. 6. How to give ducklings insulation temperature is the main technical measure for brooding ducks. Only when the temperature is appropriate, the ducklings consume less body heat, the growth and development are fast, and the survival rate is high. Umbrella nanny brooding is currently widely used brooding methods, as long as there is a power supply can be used. In addition, it is also possible to use a fire to warm the brood. The use of fire to warm the brooding must export smoke and harmful gases into the brooding room to prevent carbon monoxide poisoning of ducklings. When the young ducklings are at one day old, the actual temperature of the ducklings under the nanny should be kept at 30Â°C-32Â°C and room temperature at 22Â°C-24Â°C. After that, the ducklings increase with age and decrease by 1Â°C daily until ambient temperature. No longer cool down after agreement. To raise or lower the temperature under different climatic conditions, the behavior and performance of the duckling should prevail, and the response of the duckling to the optimal temperature requirement should be satisfied as much as possible. For example, when the temperature is too low, the ducklings are afraid of the cold and get together near the heat source, heating each other, often causing crushing or suffocating death. When the temperature is too high, the ducklings are far away from the heat source, open their mouths, and increase their drinking capacity; when the temperature is normal, The ducklings are full of spirit, lively, good appetite, moderate drinking water, light hair, stretched legs, stretched waist, quietly lying, silent, eating, drinking, and excreting normal. 7. The breeding density of ducklings and the breeding density of grouped ducklings should be appropriate. If the breeding density is too high, the duck house will be damp and the air will be polluted, which will lead to poor growth of the young ducklings. If the density is too small, the site and human resources will be wasted and the benefit will be reduced. The breeding density of the ducklings is preferably 20 ducklings per square meter for the first week of age. After that, the ducklings can gradually reduce the rearing density by no more than 10 feathers per square meter. Each group of ducks with 250 -300 is appropriate. 8, ducklings to ventilate ventilation This is because the duckling metabolism is strong. For example, environmental pollution in duck housings and brooding rooms, non-circulation of air, carbon dioxide from ducklings, and harmful gases such as ammonia gas and hydrogen sulfide generated from the decomposition of residues will harm ducklings' health. In severe cases, it will cause ammonia poisoning in ducklings. A large number of deaths. Therefore, it is necessary to maintain the air circulation in the brooding room at any time, maintain proper ventilation, maintain fresh indoor air, eliminate excess indoor moisture, keep the duck house dry and clean, and improve the living environment of the ducks, so as to promote the healthy and rapid growth of the ducks. 9, ducklings to carry out water activities to ducklings to carry out water activities, can promote the ducklings metabolism, enhance their physique and can clean the feathers on the dirt. If the duck does not discharge water for a long time, the duck hair will not be resistant to water, so the ducklings must be allowed to discharge water. The water discharge activities of ducklings are generally carried out 2 days to 3 days after hatching. The number and time of daily water discharge should be determined according to the season and the age of the duck. In the winter and spring season, water is discharged 2 times - 3 times a day for 10 minutes - 15 minutes (except in the north); in summer and autumn, ducklings in a week are discharged 4 to 6 times a day for 20 minutes to 30 minutes each time. Ducklings over 1 week old should not be allowed to discharge water at high temperatures in the mid-afternoon and can grazing in the water all day long. However, management must be strengthened.
Carrot is a kind of vegetable which is rich in nutrition and easy to process. The raw materials are bright red, the section yellow core is small, and the luster is not damaged. Processing should be selected one by one, cut off the non-edible parts, wash 2 to 3 times, according to the requirements of cutting into various shapes, such as block, sheet, stripe, dice, round pattern, stripe pattern, etc. the remaining material is generally processed into dice. The products used for export should be removed according to the requirements of merchants, and the peeling machine can be used for mass production. The processed products are blanched for 1-3 minutes in the hot water of 100 C in the basket. The blanching degree should be strictly controlled. If the blanching is excessive, the products will become soft and discolored, which will affect the quality of the products. After blanching, chill to below 10 C, drain on the vibrating drainer, freeze in the quick freezing device for 10 minutes, and pack quantitatively and refrigerate.
