First, the duck production must use orthogonal mode
Orthogonal refers to the use of the Muscovy duck as a parent, and the local high-yield duck as a maternity model. The condition of being a male parent is that if it has the characteristics of large size, fast growth, and good meat quality, it can be selected. Muscovy ducks have the condition of being a male parent; local breeder duck eggs produce much more than female Muscovy ducks, no doubt Is the ideal mother. In addition, the hybrid duck produced using the orthogonal model not only has the characteristics of rapid growth and large body size, but also has no difference in male and female duck body types, and grows as fast, which overcomes the shortcomings of large backyard male ducks and small female ducks.
Second, choose the right parent combination
The current production of ducks has three types of large, medium and small types.
1. The parent group of large ducks. First, the French cremo white plumage duck (CR) ♂ Beijing duck quail; Second, China's white feathers Muscovy duck Cherry Valley duck SM ♀. Although the ducks of the two combined productions can achieve the goal of large size and fast growth, the disadvantages are that the female body type is too large, the material consumption is large, and the production of eggs is low, so the production cost is high.
2. Mid-sized duck family. There are three types: (1) Chinese White Feather Muscovy Duck Beijing Pelican; (2) French Cremo White Feather Muscovy Duck (CR) Uo Jianchang Duck or Gaoyou Duck Meal; (3) Chinese White Feather Muscovy Ducks Beijin, Beisha , Beijiao three generations of hybrid duck soup. The maternal egg production performance of the first two groups is poor, so the cost of seed production is relatively high. The current production uses more of the latter combination.
3. The parent group of small ducks. There are three kinds: (1) Chinese white feathers, ducks, ducks, and ducks; (2) China's white feathers, ducks and ducks, Shaoxing Ducklings; (3) Chinese white feathers, Muscovy ducks, Putian ducks and ducks. In addition to the female parent of the above three combinations, the female ducks of other local breeds in China can also be used instead, but due to the lower egg production, the production cost is slightly higher.
In order to increase fecundity and gain competitive advantage, Beijing duck male ducks may be selected as the first male parent, then Jinding female duck (Beijin), or Shaoxing female duck (North Shao), or Putian female duck (beijing) ) Hybridization. The two-hybrid female ducks were crossed with white muscovy ducks. This not only overcomes the shortcomings of the mother's low egg production, but also obtains medium-sized ducks with stronger heterosis, so it is welcomed and is currently the most commonly used and most effective method in production.
Third, the father should use large white feather duck species
Muscovy ducks are divided into feathers, white feathers, black feathers, and flower feathers. If they are divided by body size, they are large and medium-sized. The father of the production of ducks and ducks is preferably a white feather large breed. For example, the French Cree Muscovy Duck R51 or the white feathered Muscovy Duck selected by the Fujian Agricultural University are all ideal choices, because large breeds are used as paternal ducks. The body size and growth rate have a great influence. In addition, due to the high economic value of white down feathers, there is no residual black hair root on the carcasses after slaughtering of ducks, and the carcass is bright and clean, which is generally welcomed by consumers at home and abroad.
Here we must pay special attention to the producers of farms: Do not use the small, degraded local Muscovy ducks as male parents.
Fourth, the use of artificial insemination technology is the key
Because the two parents of the emu duck are far from each other, natural mating is difficult, and the fertility rate is very low, so that the production utilization rate is very low. The use of artificial insemination technology can greatly increase the utilization rate and fertilization rate of male ducks, and greatly reduce the cost of seed production. Under normal circumstances, the use of natural mating, Muscovy duck male to female ratio is 1: 4 to 5, while the use of artificial insemination technology, male and female ratio up to 1:20 or more, the utilization of duck increased by more than 4 times . When natural mating, the fertilization rate is generally only about 30%, while the use of artificial insemination technology, the fertility rate of up to 75%. If the duck is well-fed, the skilled inseminator is experienced and skilled in operation, and the fertilization rate can be as high as 85%.
Fifth, when feeding, according to local conditions
Muscovy ducks and most local duck breeds can be used to produce ducks and ducks. When farmers select their parents, they must select high-yield local varieties suitable for local environment production so that they can adapt to the local environment.
1. Decomposition: biodegradable excess body fat, flat meat, all kinds of stone decomposition, promote the decomposition of food digestion and absorption.
2. Blood purification: Arrange internal environment, purify the blood and improve physical fitness - decomposition, eliminate waste, the blood becomes acid.
3. activation: the pituitary gland to stimulate cell regeneration, a recession is not easy to remember, can not afford to skin wrinkles, youthful beauty delay human aging.
4. Anti-inflammatory antibacterial effect: enzymes can strengthen the fight against white blood cells and remove invading bacteria and purulent matter, the cells speed recovery and enhance wound healing
5. hangover, hangover prevention.
6. For picky eaters, do not like to eat fruits and vegetables children the best nutritional supplements and energy sources.
It contains nutrients more easily absorbed by the body, containing amino acids, polysaccharides, protein components, vitamins B, C, E, and trace elements needed by the body. Long-term use, long-term preservation.
Help prevent hardening of the arteries, lower cholesterol, fat decomposition and excretion of non-ferrous metals and radioactive elements and balance the body's composition, help prevent cancer and other diseases, promote blood circulation and metabolism, recuperate, enhance physical fitness, health protection.
Companies registered capital of 35 million yuan, the end of 2014 the total assets of 48.69 million yuan, including fixed assets of 37.52 million yuan. The company's existing cooperation Orange cultivation base 7043.5 acres, the company production base is located in Jiangxi County Tech Industrial Park Chu Tan industrial area, covers an area of 120 acres, it has built a standard plant 9,000 square meters, Nissan 6000 kg Orange enzymes and other liquid enzyme products. Enzyme, known as enzyme, refers to a polymer substance having biocatalytic functionality. In the catalytic reaction system an enzyme, the reactant molecules are known as substrates, enzyme substrates by catalytic conversion to another molecule. Almost all cellular activity of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts, enzymes chemical reactions by lowering the activation energy to accelerate the rate of the reaction, most of the enzyme catalyzed reaction rate can be increased a million times; in fact, the enzyme is to provide an activation energy needs than another low way, so that more particles to have less than the activation energy of the reaction kinetic energy, thus speeding up the reaction rate. Enzyme as a catalyst, in itself is not consumed during the reaction, it does not affect the chemical equilibrium reactions. Positive enzyme catalysis, but also a negative catalytic effect, not only to accelerate the reaction rate, but also to reduce the reaction rate. And other non-living catalysts is different, having a high degree of specificity of enzyme, only a catalytic reaction or produce a particular specific configuration.
