First, choose to stay in the fine breed duck 1. The choice of ducklings should be early hatching, soft and elastic abdomen, good umbilical cord contraction, bright eyes, strong and lively, ducklings weighing about 55 grams. When choosing ducklings, it is best to be able to duck male and female Separate and enter the ducklings at a ratio of 1:4 to reduce feeding costs. 2. The reserved ducklings for reserved ducks are selected for retention at the age of 60 days. The main criteria for selection are: (1) Good health condition. Healthy duck feathers, hair growth is neat and clean; Eyes are bright and there are no secretions near eyes and anus. Pollution, neck flexibility, clean legs and feet; action flexibility, gait stability. (2) appearance and body characteristics in line with the varieties. The drake requires a thick and short head and a rectangular body. The back is flat and wide, the chest is generous, and the sole is powerful, weighing about 2.5 kilograms. The female duck body is slightly shorter and wider than the male, and the head and neck are slightly smaller, weighing about 2.2 kilograms. The ratio of male to female is 1:8. Second, feeding and management 1. Feeding and management of ducklings Before hatching, we must prepare for brooding. The ducklings are transported from the hatchery to the brooding room. The 0.1% potassium permanganate solution is first used to feed the ducklings. The water can be eaten at the same time. Open the food method: Mix the full-price compound feed with wet, add appropriate amount of milk powder and multi-dimensional pigment and sprinkle on the plastic cloth; 1 to 2 days later, feed the full-price compound feed. Feed 1 to 2 weeks every day from 8 to 10 Secondly, after 2 weeks, it gradually transitioned to feeding 4 to 5 times a day. During the entire brooding period, care should be taken to keep warm and prevent ducklings from playing “sweatâ€. 2. Feeding management of reserve ducks (1) Appropriate grazing. When the young ducks are raised to the age of 30 days, proper grazing is started. Before grazing, the artificial temperature must be stopped so that the duck population gradually adapts to the outside temperature. The grazing time should be short at the beginning and then gradually extended. To 5 to 6 hours a day. (2) Feed restriction against early maturing, ducklings 0 to 28 days of age, generally not limited to feeding; 5 to 18 weeks of age, to limit feeding, that is, according to the meat breeding duck feeding standards, species The growth and development of ducks determine the feeding amount of ducks, and gradually reduce the protein content of feeds from 20% to about 16%; after 18 weeks of age until the start of production (about 26 weeks), feeds should be added in a timely manner. The protein in the feed increases the amount of feed daily. 3. The management of egg-producing ducks requires that the ducks maintain a high peak of egg production for a long time and increase egg production. Comprehensive measures must be taken to increase the number of feeds per day and extend the intake time; improve the palatability of feeds and add a small amount of animal-based products. Feed (such as cooked snail meat, oyster meat, etc.); keep the duck house cool in winter and cool in summer, use cold water to mix in the hot season and increase the number of feeds at night, use warm water to mix in winter. In order to obtain quantity and good quality Eggs, but also to take the following measures: (1) diligent eggs. Many ducks produce eggs at 2 to 5 am every day. If eggs are not cooked in time, the eggs are easily frozen in winter, and the eggs are easily contaminated in summer. Therefore, eggs must be quailed 3 to 4 times a day. (2) Prevent stress, Reduce the misshapen eggs. The living environment of the duck must be relatively stable; other livestock and poultry must not be close to the breeding ducks; the feeding and feeding of the keeper must be lighter. (3) Increase the calcium content of the feed to reduce shell or soft shell eggs. 3. The sanitation and epidemic prevention duck house and its surrounding environment should be regularly sterilized; no outsiders are allowed to visit; the keeper who enters the duck house should put on the disinfected work clothes, shoes and caps; keep the house clean and dry, and change the litter; Moldy feed. In addition, the vaccine should be injected regularly: 14-day-old and 140-day-old were injected with duck plague vaccine; 60-day-old and 100-day-old were injected with fowl cholera vaccine.
With the improvement of living standards, snack foods have been deeply loved by the masses of the people. When you walk into the supermarket, you will see snacks such as preserved fruit, sour horns, potato chips, almonds, pistachios, fish fillets, dried meat, and spiced fried meat. Snack foods are gradually upgrading to become the daily necessities of the people. As the economy develops and the level of consumption increases, consumers' demand for the quantity and quality of snack foods continues to grow.
The content of sarcosine in beef is higher than any other food, and it is particularly effective for growing muscle and strengthening strength. In the first few seconds of training, sarcosine is the source of muscle fuel, effectively supplementing adenosine triphosphate, allowing training to last longer.
