Pay attention to doing a good job of keeping warm and ventilating
From hot summer to cool autumn, the temperature drops sharply, and the temperature difference between day and night also increases. The temperature difference in the north reaches more than 10°C. Occasionally, there will be strong winds, and even many places will feel the taste of winter in a short time. It has a great impact on the growth of pigs, especially wet and cold concrete floors, which not only greatly increase the incidence of herds, but also reduce the feed remuneration of pigs. For piglets, this climate change will also cause diarrhoea and diarrhoea, causing many diseases. Therefore, appropriate measures should be taken at this time to control the temperature in the pig house and reduce the impact of the temperature difference. It has become a task that the farm chief must consider and implement. The specific measures are as follows:
(1) Maintenance of pig houses: Intrusion of thieves into the pig house to attack pigs can cause diseases such as colds and pneumonia in pigs. Therefore, repair works such as doors, windows, glass, protective covers, etc., should be closed at night. Doors and windows to prevent all kinds of thieves; can also be used from the outside with a roller blind (single or double plastic film, plastic cloth) for insulation.
(2) Adding insulation layer to the pig house: Closed-type pig house, with a height of 1.8 to 2.0 meters above the ground from the ground, adding sawdust and rice husk to the shed, laying grass on the ground for the pig to lie down. A vent is left every two days in the ceiling to remove ammonia and moisture from the house. Conditional farms can use heating and infrared light bulbs at night. No conditions can also be used to cover plastic sheeting, hanging grass curtains and other measures to keep the pig house at a suitable temperature. The suitable temperature for 1 day to 3 days is 30°C to 32°C, the suitable temperature for 4 days to 7 days is 28°C to 30°C, and the suitable temperature for 15 days to 30 days is 22°C to 25°C. . The temperature of the nursing house should be kept above 20°C, the temperature of the nursery and the nursing house should be kept above 22°C, and the temperature of the newly weaned piglets should be maintained at about 26°C.
(3) Pay attention to ventilation and ventilation of the pig house: The pig house should be insulated, ease the temperature difference and strengthen the ventilation, prevent air pollution, and make reasonable adjustments according to the actual situation. If there is more ventilation in sunny days and less ventilation in rainy days, it is better to choose ventilation time for higher temperatures. Generally, the best time for ventilation is from 10 am to 3 pm.
(4) Adding nutritional supplements: Forwell's products, Forwell (pig), 500 tons of mixed spices, 1 ton, drinking water, 1:2000. At the same time, we can use the micro-ecological agent Vivienne (specialty for farms), add 500 g/ton of spices, regulate the intestinal health of pigs, and improve immunity.
(5) The pig house is kept dry: The higher the humidity in the pig house, the colder the pig feels and the pig's skin, respiratory, infectious and parasitic diseases. In order to prevent moisture and leaks, the pigs should be allowed to defecate urine and keep the pig's prone position clean and dry. Some detergent (powder) products can be used to spray the sheds, which can both dry and reduce bacterial growth. Give pigs a comfortable living environment.
Adjust the breeding plan and do a lot of farm management
The problem of sows not estrus and low fertility rates due to high temperatures and disease infections is coming to an end. After autumn, there will be a large number of sows to be bred, and there will be obvious estrus. If uncontrolled breeding, there will be peak calving during the Spring Festival. The emergence of. People frequently flow during the Spring Festival, and people's hearts are unstable. If you add a large amount of workload at the height of the farrowing cycle, common disease epidemics and high mortality rates may occur, and more pigs do not bring in more slaughter results. Therefore, breeding in the autumn should not be excessive and should be carried out in accordance with the normal breeding program so as to avoid undue losses. This requires that the farm be strictly implemented as planned.
Reflective tape
Jerry tape has a wide range of reflective tapes. Our reflective tape has different kinds of materials, and they are suitable for diffierent applications. Blow are the ranges we have:
1) Advertisement grade Reflective Sheeting
Our advertisement grade reflective sheeting also have different serious: 3100, 3200, 5100, 5200, 7100 and 7200.
Which is based on PVC material, more bright, service life is 1~3 years.
3). High intensity grade reflective tape
Based on first class PET/ PC/ Acrylic material, adopted reflection principle of glass beads, has better reflective effect and longer service life. Also has DOT-C2 and Solas certificate.
4). Micro prismatic grade reflective tape
This grade of reflective tape is based on the Reflection principle of diamond prism, has perfect reflection and longer service life, can meet the application of freeway, heavy-duty vehicle, etc.
