In recent years, the livestock industry of Lam Dong province has gradually shifted from self-sufficiency and self-sufficiency to commodity breeding. Many families have chosen breeding career .
In the selected animals, the industrial chicken was of interest to families in Da Lat City, Bao Loc Town and densely populated areas. In the last two years, the number of industrial chicken raised in households has increased from 5,000 (1990) to about 20,000. The reason for the strong industrial chicken flock is by taking advantage of family labor, investment is not large, fast products, easy product consumption and high economic efficiency.
In order to help farmers have a more technical solution to solve some common problems in industrial chicken farming, we introduce a chicken quarry cutting method and recommendations for use in industrial chicken farming in the home. family.
First of all to solve the problem that is often seen in industrial chicken production: The phenomenon of chickens in a flock striking, eating, eating each other; laying hens can easily break eggs, anal anatomy, rectal tearing, other gut and gut eating . When this phenomenon occurs, the development is usually in the direction of increasing and causing damage in economic terms (there is a case where it is impossible to continue animal husbandry).
The phenomenon of chicken pecking, furry eating, meat eating together may be due to some reasons:
To overcome the above reasons, many chicken breeding experts and researchers such as Godfrey (1962), Misersky (1968), Romagosa (1968), Crozco (1969) Monne (1971) claim that the law Chicken mine cutting is most effective .
Secondly: cutting chicken beaks to save food for one unit of product by limiting the amount of spilled food and increasing the efficiency of food absorption.
According to the author Bushman (1978), he experimented and concluded with equipment and tools specialized for industrial chicken farming, for chickens without cutting, the amount of feed dropped about 2-3%. In many other test cases, the rate of spilled food is even greater.
In the experiments of our aforementioned and experimental authors (1981) (including 1248 chicken-like chickens, of which 624 miners) achieved the same results, only feed consumption was used for one application. The product taste in the cut chickens is lower than the control, the reliability is 95%.
In terms of rearing rate in mined chickens, the authors also informed that there was no difference between experimental and control groups. In the cut-off flock there is a more 'peaceful' life and a marked reduction in incidents.
For farmed roosters to breed, of course, do not carry out cutting .
Many experiments have carried out cutting chickens at all ages, but the most common conclusion is that the chickens should be cut after 12 days of age because at the old days, chickens were cut easily and stunned (Stress) and the mine was left so small that the implementation is difficult.
According to our experience, depending on the breed of chickens and the technical conditions of breeding to determine the age of mine cutting:
According to the experience and guidelines of chicken producers, the portion of the mine to be cut has a ratio of 1/3 to 1/2 of the upper part and corresponds to 1/4 and 1/3 of the lower mine section. .
Our experience is as follows:
Cut back the chicken beak when the chicken is too long or the upper part and the lower part has an unbalanced length, it is necessary to cut and 'fix' so that it corresponds to the previous cut.
In our experience, we do not cut chickens when it is over 30 degrees Celsius because it is easy to stimulate blood flow; Do not do it when it is cold under 15 degrees Celsius because it will cause chicken pain when drinking cold water.
This method is carried out in breeding establishments with a large number of thousands. The cutter has a blade that is heated by electricity, and has a technician who specializes in mine cutting.
Cutting mine by manual method
This method is applied in industrial chicken farming on a family scale with self-created tools and 2-person work needs. The following is the content of the method:
Chicken mine cutting tools include:
The work proceeds in the following order:
After the chickens are cut, the observation should be observed for a few hours, if any of the children bleed the cut, they will cut the cut with a red-hot knife.
Frequently refill the food and water into the chicken trough easily and do not hurt the cut.
