Goose geese large-scale farming technology
(I) Main technical points for breeding goslings Goslings refer to goose from the shell to the age of 4 weeks. At this stage, the gosling has fast growth and development, weak digestion, and poor ability to regulate body temperature. It must be meticulously reared and managed and necessary protective measures must be taken. 1. Choose healthy young chicks: choose a healthy physique, stand steadily, be younger, be on time, individual large (about 100 grams), long thick hair, shiny, eyefulness, no deformity, umbilical good contraction, abdominal soft, struggling Turn over the fast-turning goslings. 2. Early watering: The first time the goslings drink water "boiling water". General goslings are released 24-26 hours after hatching, or they are properly rested after being shipped back. When the fluff is dry, it can be given. Drinking water temperature to 25 °C is appropriate, water quality should be clean, drinking water can be added 0.05% potassium permanganate or 5% -10% glucose and the amount of vitamin B complex solution. When you “waterâ€, gently press the head of the gosling in the water to allow it to freely drink water. Drinking fountains are fixed, do not cut off water, and gradually transition to the release of water. 3. Open food at the right time: After boiling water, most of the goslings have already started drinking water (5-10 minutes after drinking). The starter feed is made with concentrated feed and a small amount of green feed for shredding. The method of eating can spread the feed on plastic sheets or mats to induce young geese to eat freely. The proportion of refined and green materials is generally 1:2 before 4 days of age, 1:2.5 of 4-10 days, and 1:4 after 10 days of age. Green material can use tender grass or leaves, wash and chop. In the early brooding period (the first 3 days), the concentrate is mainly rice, after which it is slowly blended with compound materials. After 1 week of age, all the compound feeds are fed. Feed feeding times were generally 6-8 times daily before 3 days of age, 8 times on 4-10 days, 6 times on 10-20 days, and 4 times after 20 days. 4. Insulation and dehumidification: Goslings insulation depends on the brooding season and climate, and generally require artificial insulation for 3-4 weeks. The number of thermometers is determined by the size of the brood chamber, and the thermometer is suspended at a height of 15-20 cm from the ground. The principle of temperature control is that the small group is slightly higher, and the large group is slightly lower; the younger ones are slightly taller and the younger ones are slightly lower; the cold days are slightly higher and the hot days are slightly lower; the nights are slightly higher and the days are slightly lower. The temperature is suitable, the goslings are evenly distributed, lively and active, quiet rest, and occasionally issued a light cry, although they like to rely on each other, but do not fight. The temperature is low, the goslings are concentrated in piles of heat, the back hairs are damp, and low and long buzzing sounds are generated. If the temperature is too high, goslings are far away from heat, gasping their mouths, drinking lots of water, losing their appetite, and disturbing their actions. They should stop heating or cooling. The general temperature requirements are: 27-29°C on Day 1-5, 25-27°C on 6-10 days, 23-25°C on 11-15 days, and 18-23°C on 16-20 days. Humidity and temperature also have a great influence on the health of goslings. The two interact. The brooding room should be kept dry and clean with a relative humidity of 60%-70%. The low temperature and high humidity make the goslings emit heat quickly and feel colder. As a result, the resistance decreases, causing piles, colds, and diarrhea, resulting in an increase in the number of dead geese, deceased geese, and deaths. High temperature and high humidity make it difficult for the body heat of goslings to be distributed, and the appetite of goslings declines, which can easily lead to the proliferation of pathogenic bacteria and increase the incidence of goslings. Therefore, we must pay attention to prevent the brooding room too wet, often change or add litter, water should not spill, strengthen ventilation, the necessary moisture can also be used lime. 5. Reasonable grouping: As the goslings grow up, they should be grouped in a timely manner. General requirements for brooding densities are: 1-5 days old 25-20 feathers per square meter; 6-10 days old 20-15 feathers per square meter; 11-15 days old 15-12 feathers per square meter; 16-20 days old 12-8 feathers per square meter; the density gradually decreases after 20 days of age. Grouping should be based on the size of the goslings, strength and weakness, each group (column) with 25-30 feathers is appropriate. In order to improve the uniformity, it is necessary to strengthen the management of weak groups and small groups. 6. Pay attention to the release of water: Goose is a waterfowl, and it is necessary to release water to improve the geese's constitution and enhance resistance. Generally about 1 week brooding, you can choose the warmer weather, sunny windless weather for the release of water, the initial release of water should be in shallow ponds, the water temperature is appropriate at about 25 °C, free to enter the water after a few minutes to catch up. However, in the cold days, it is necessary to prevent the release of water and cause freezing.
Black glutinous maize is a special type of maize, whose kernel cuticle deposits melanin to varying degrees, giving it a dark and shiny appearance. The kernels are rich in water-soluble melanin and various essential trace elements, plant protein and various amino acids, with a significantly higher nutritional content than other cereal crops.
The origin of black glutinous maize: coloured glutinous maize is generally white, yellow, red, purple and black, with white, yellow and purple maize being the basic colours. The purple gene of a purple-white cross naturally becomes purple if it "beats" the white gene, and vice versa, so if the two make a tie, we see white and purple maize. Purple can turn into red and black maize, or as we often say, "red is purple and black is purple".
