Many years of practice have proved that the fermentation bed not only has a significant effect on raising pigs, but also has a significant effect on animals such as chickens, ducks and geese. According to the long-term application of the technology of ducklings in the Inner Mongolia Saifei Group and the Hebei Sanyuan Duck Industry Co., Ltd., ducks in the fermentation bed not only deodorize the environment, save energy, save food, and save water, but also promote disease resistance. To improve the quality of duck meat, as long as the maintenance and management are properly carried out, the fermentation bed can run well for a long time. Need to remind the majority of farmers are: fermentation bed ducks in the maintenance and management process should pay attention to the following points:
1. Control the density of duck houses. The growth stages of ducks are different, and the size and excretion of feces and urine are not the same. Therefore, the density must be properly arranged. For example, ducklings 25 days ago, the fermentation bed can withstand a culture density of 7-8 eggs per square meter or more. After 25 days, as the excretion of ducks gradually increased beyond the load on the fermentation bed, the culture density should be reduced. It is recommended to use the “AB loop or A BC loop†system for the Jinbao Dry Fermenting Bed, that is, 25 days before the use of a small area A circle, and then 25 days later to activate B, C large pen homes, such as the original 1 duck group Divided into two, or two duck groups are divided into three, or replace the original small-area housing into a double-area large-scale house, and set a dedicated channel in the middle or both ends to reduce the breeding density, reduce the excretion, and make the fermentation bed Long-term, stable and continuous function.
2, to strengthen the ventilation of duck houses. The normal operation of the fermentation bed requires the participation of sufficient oxygen. At the same time, excessive concentration of NH3 and CO2 as an intermediate product will affect the Respiratory system of ducks and humans. Therefore, the ventilation of the fermentation bed is critical. Therefore, it is possible to combine skylights (with power and non-powered sunroof spaced and arranged in zigzag, 3 to 5 meters in length), underground windows (alternating between powered and unpowered windows, 3 to 5 meters in size), roller shutters , fans, etc. to enhance ventilation in the duck house. The first is the natural ventilation of the doors and windows; the second is the mechanical ventilation; the third, the use of sunroof, the formation of the circular air flow ventilation; Fourth, forced ventilation, the use of fans, induced draft fan ventilation. For example, during the hot summer period, all the curtains need to be opened, and the exhaust fan or chiller is used to cool or adjust the temperature regularly. In winter, depending on the temperature and humidity of the specific house, it takes 2 to 3 times a day to use a forced draft fan to open the window for ventilation. 3 to 5 minutes (or adjust ventilation time as appropriate).
3, frequently turned duck litter. If the fermentation bed does not turn over for a long period of time, the excrement cannot be easily fermented by microorganisms due to its uneven distribution, and harmful gas can also produce a phenomenon of “dead bed†in the fermentation bed. Therefore, it is necessary to strengthen the turning of litter in daily feeding work. The frequency is generally 1 or 2 times a week, and the depth of the fermentation bed is 10 to 20 cm, which facilitates full fermentation. It's best to use a machine to overturn it. When it's tipped over, it's time to increase the intensity of the exhaust.
4, pay attention to duck moisture. The jinbao dry spreader bed, afraid of wet not afraid of dry. In order to prevent the ducks from spilling water on the fermentation bed when drinking water, a floor drain can be used to cover the bottom of the sink to prevent the rest of the water from flowing to the fermentation bed. In addition, during the thunderstorm period in summer, the drainage outside the duck house should be kept clear and there should be no seepage of water.
5, timely disinfection. For empty-bed fermentation beds, disinfectants can be normally sprayed if necessary (in case of an outbreak) without affecting the continued use of the fermentation bed. However, the general fermentation bed is a “sterile bedâ€. The main task is to disinfect the peripheral walls, aisles, etc. with disinfectant liquid and lime. After the slaughter, the fermentation bed is fully cleared (so that it can be fully fermented ) If necessary, place the litter on the ground and disinfect and disinfect it, add some fresh litter, add strains as appropriate, and arrange the fermentation bed to overhaul the drinking fountains, water tanks, pipes, and ditches.
6, a reasonable arrangement "bed." The fermentation bed should be maintained scientifically and reasonably to extend the service life of the fermentation bed and increase its efficiency. Wet areas or duck beds in a bed where the fermentation bed is too wet can be arranged for a period of 7 to 10 days after the batch of ducks are slaughtered. During the rest period, the wet litter is brought together into a larger pile (60 to 120 cm). ) Turn over 1 or 2 times during the period of use, sterilize by fermentation, run the water, and finally flatten out, creating a good environment to welcome the next batch of ducks into the circle.
7, timely supplement padding. The fermentation bed runs for a period of time. Due to the start of fermentation of the litter and the ingestion and stamping of the duck, the litter will consume part of it, thus requiring the addition of a portion of the litter and appropriate strains. Under normal circumstances, one or two times a year added bacteria and litter. One principle is always adhered to: The dunnage of the ducks in the Gumba Dry Sausage Fermentation Bed can't be significantly lower than 40 cm. If it is obviously less than 40 cm, the litter should be added in time and the bacteria should be added as appropriate. Details can be consulted: Beijing Huaxia Kangyuan Technology Co., Ltd.
