Leg Problem Controlling


Leg problems are caused by multiple factors (multifactorial), sometimes also referred to as diseases associated with management (management related diseases) is one one that needs attention, because it causes an increase in depletion (culling) the amount quite significant.

Leg incident handling and prevention of problems must be done in parallel between the improvement management and medication regimen. Management improvements will minimize the factors Leg predisposition that causes problems. Medication regimen will minimize contamination levels in cages and suppress the infection in the body of chicken. If all run simultaneously, it is expected to make the performance better, because all potential chicken will appear. Factors genetic flaws that cause frequent occurrence of Leg problems can be minimized by the conditions inside the enclosure sufficient comfort.
Control / Control Leg problems done in the following way:

1. With management control:
     To prevent the occurrence of leg problems, it is necessary to note a few important things could affect  the infection in the field, is as follows:
     - The sterility of the vaccine at the time of application:
        i. Control at the time of sterile tools vaccine, whether it is appropriate IK.

        ii. Controls when installing a hose into the infusion bottle and at the turn of the bottle, whether done in sterile and carried on where clean.

        iii. Controls whether the replacement was appropriate needle and the needle did not work instructions
            dirty, not hand-held.

        iv. Controls whether the needle used to puncture the bottle (so that the air  into the bottle) the existing 

        v. Controls whether alcohol was carrying equipment for hand sanitation and equipment.

        vi.Controls whether the syringes and needles are used to dissolve the vaccine is always
            in a closed condition and clean.

    - Inspection of the condition and the equipment inside the enclosure:

       i. Control inside the cage, if there sharp objects (nails, wire)
          used on walls, floors, slat, ladder, nest boxes, automatic feeder, etc.. Has it been fitted top grill on grill 
          automatic feeder.

      ii. Humidity control litter is too wet, causing manure or litter attached to the leg.

      iii. Is the level too high ammoniak caused by impurities wet suit that is too big a place to drink or drinking 
          place the leak. Ammoniak high can cause burning ammoniak which causes the foot to be broken.

      iv. Density control in a cage or pen, if the density is too high, whether the feed and drinking places is   
           enough. Density height is a factor predisposing to Leg problems.

          Coccidiosis Control status:
i. At control conditions inside the enclosure using adequate lighting
   (Battery), so they can see more detail.

ii. Is the condition of healthy birds, feathers do not stand up and dull, good mobility.

iii. Is not there a dilute impurities such as orange-colored pasta, red or black.

iv. If there are symptoms of cocci, it is necessary to further observation by doing a post mortem examination   to determine whether infestations occur cocci.

v. If there is clinical and subclinical cocci, then immediately do medication. Conditions of weak chicken and injury to the bowel makes the factor predisposes to leg problems.

2. Prevention / control with antibiotics through feed (medicated feed): Antibiotics are meant to reduce the number of pathogenic bacteria in the body chickens, so there is no exposure to excessive bacteria in the cage. Medicated feed given to the farm at present there are clinical symptoms of leg problems or on farm based on the history of frequent cases of leg problems in the previous period. Medicated feed to control Leg problems were coded as "Med A" by using antibiotic Amoxycillin with a dose of 100 ppm. Amoxycillin can serve as a control Staphylococcus sp., Necrotic enteritis and Salmonella sp.

The way of feeding "medicated" as follows:
- Each package for the treatment of leg problems include: provision of Amoxycillin Powder
   for 5 days through drinking water at a dose of 40 mg / kg, followed by feeding "Med A" for 14 days.
- Control of leg problems using feed "medicated", given from 8 weeks, the next administration with an interval of 4 weeks from the last day administration and given up to the age of initial production (control Leg problems
given at the age of 8, 15 and 22 weeks).

- Leg Treatment problem: if there is a farm that already contained Leg problems,
then to be given treatment for leg problems as much as 2 packages, with interval of 4 weeks.
- If there is a farm that has leg problems and Mycoplasmosis in simultaneously then the control program is given control program Mycoplasma, because mycoplasma control program can also be used as a program
Leg control problems.

3. Monitor events Leg Problems:

Farm should be monitored early to determine the prevention measures in order
no delay in handling, so not to cause chicken
culling in large numbers. For it is necessary for monitoring the incidence Leg problems
as follows:

- Monitor the inspection:

i. Take control when chickens began eating in the morning. If there
   limping chicken, then immediately remove it from the cage.
ii. In the event of a fairly significant increase in the number, then immediately
   do shipping samples of serum and chicken to the Laboratory.

iii. Verify whether the occurrence of infections caused by viruses, MS or
    Staphylococcus sp. To ensure viral arthritis can be done with
    how post-mortem examination and histopathology. For MS examination can be done
    with serology test.
