Editor's note: Autumn is the most suitable season for livestock and poultry breeding. For the livestock industry, the season of the year is "autumn." In order to help farmers to better breed livestock and poultry, we invited some experts from the Provincial Animal Husbandry and Veterinary Bureau to open up some of the autumn management of livestock and poultry.
chicken
Provincial Animal Husbandry and Veterinary Bureau senior animal clerk Jin Liang: The autumn climate is very suitable for raising chickens, especially for breeders and laying hens, and management should be strengthened for fattening and high yield.
Improved nutrient composition Chickens are already fatigued after long-term egg production and hot summers, and should increase protein content in the feed after fall. Because the chicken's nerves are very sensitive at this time, when increasing the more nutritious feed, it is necessary to pay attention to a slow increase, so as not to reduce the stimulation of the chicken's nerves. To feed more easily digestible high-quality feeds and vitamins, especially B vitamins should be sufficient.
Supplemental artificial lighting For laying hens, the light during the laying period should be gradually extended, the light intensity should be gradually increased, not suddenly increase, so as not to produce stress on the chicken. The natural light in the autumn is gradually shortened, and the farmers should adjust the turn-on time in time, pay attention to keep the light time and light intensity constant, in order to avoid the chicken moulting, affecting the production of eggs. Generally, a 40-watt incandescent lamp is installed in a 20-square-metre chicken house with a lampshade. The lamp is 1.5-2 meters away from the ground. Each morning and evening light is turned on for a certain period of time, plus daylight hours. The daily illumination time is up to 16.5 hours is appropriate.
The suitable temperature for regulating the growth of laying environment is 13-24°C, and the relative humidity is 50-75%. Too high and too low will reduce the chicken's egg production rate. When the autumn weather is hot, chicken respiratory tract and intestinal infectious diseases are easily caused. Therefore, ventilation and ventilation must be strengthened. Open doors and windows during the day to increase ventilation; appropriate ventilation at night to reduce the temperature and humidity.
duck
Provincial Animal Husbandry and Veterinary Bureau senior animal clerk Jin Liang: In the autumn, the temperature gradually drops, the temperature difference between day and night is large, and the sunshine time becomes shorter. The fall duck that hatched in the previous year, after half a year of laying, suffered physical fatigue, and had a slight carelessness in management, it would stop production and hair replacement; ducks hatched in early spring started to lay eggs from late September to mid-October. At this time, the weather gradually became cooler and the temperature difference between day and night was too great. Especially for ducks that were raised in the wild, they could not find enough food because of late autumn. They often had insufficient nutrients, which affected the production of eggs and caused the ducks to fall. Therefore, management should be strengthened in the autumn, pay attention to nutritional regulation, and maintain the stability of the environment in order to improve the production level of ducks.
To ensure certain illumination time, the natural lighting time in autumn is gradually shortened, which is not conducive to the maintenance of vigorous reproductive function of ducks and ducks. It is necessary to supplement the artificial lighting so that the daily illumination time is not less than 16 hours and the light intensity is stabilized. In general, a 40-watt incandescent lamp is installed in a 20-square-meter duck house, and a lampshade is installed. The lamp is 2 meters away from the ground. Turn on the lights in the morning, turn off the lights at sunrise, turn on the lights at night, and make up for the light for 16 hours.
Improve the level of protein in feed The animals in autumn have the property of accumulating energy and ensuring safe winterization. In this period, it is necessary to control the length of ducklings to prevent excessive fat. Appropriately reduce the feed energy or allow the duck to exercise properly, and control the fall duck weight to 1.5-2 kg. At the same time, if the protein level of the diet is properly increased, the crude protein content of the captive ducks should be increased to more than 18%. The free-range ducks should be properly supplemented with protein feeds so that it can consume enough protein to meet the egg production needs. In this way, it can be guaranteed that the fall duck will produce more eggs during the “summer heat†period until the “winter solsticeâ€. In addition, to properly supplement the inorganic salt feed, it is best to set mineral feed bowls (1 bone meal + 3 shell powders) in the duck house, allowing any duck to eat freely.
Doing a good job of preventing cold will cause a drop in temperature once the wind blows once in autumn. A sudden drop in temperature will result in a significant drop in the egg laying rate. Therefore, the change in the microclimate of the duck house should be reduced as much as possible. First of all, we must do a good job of protecting the cold in late autumn. It is best to keep the duck house at 13-20°C. Second, keep the duck shed dry. Autumn is a rainy season. The playground is prone to water. The grass in the duck house is prone to dampness and mildew. Measures must be taken to reduce the humidity in the house and prevent the grass from becoming muddy.
pig
Provincial Animal Husbandry and Veterinary Bureau senior animal clerk Lu Jianding: Autumn is also the golden season for raising pigs. At this time, the green feed is sufficient, and the quality of the pig is also good. The health pigs are just in time for the New Year's Day and the Spring Festival to be listed, which is expected to achieve better economic benefits.
1. In early autumn, the temperature is relatively high, and the pens should be kept well ventilated. Wash the pens and pigs thoroughly, and do a good job of cooling the sun. Due to the higher temperature, the feed intake of pigs will be reduced. At this time, the nutrient concentration of the feed should be increased to meet the nutritional needs of the pigs.
2. The temperature in late autumn is low, and cold air is often invaded. It is necessary to do a good job in preventing pigs from cold and keep the barns dry and clean. At the same time, to increase the amount of feed, if necessary, increase the number of feeding.
3, the temperature difference in the autumn is larger, the pig disease is also more, it is necessary to do a good job of anti-epidemic work in a timely manner, and strictly restrict personnel from entering and leaving the pig house. Do a good job in the daily cleaning of pig houses, keep them clean, and do a good job of pig immunization.
rabbit
Ren Li, senior livestock clerk of the Provincial Animal Husbandry and Veterinary Bureau: Autumn is the season of rabbit hair replacement and breeding, and management must be strengthened.
Grasping breeding is the best season for rabbits to breed in the fall. Female rabbits have high conception rates, many litter sizes, and pups are healthy and have a high survival rate. Therefore, breeding should be promoted. The females are estrus once every 8-15 days for 3-4 days. During estrus, the female acted unnervingly and her appetite subsided. The genital area was reddish in early estrus, reddened in the medium term, and reddened and swollen. Later, it became dark purple and the swelling gradually subsided. The maternal rabbits were estrus in mid-season and had the highest fertilization rate and reproductive rate. Breeding is best to take compounding. Because of the hot weather in summer, the male rabbits die dead. When the animals are bred in the fall, they should be bred twice in order to ensure quality.
Scientific feeding in autumn is the rabbit's hair replacement season. Rabbits consume more nutrients and have poor health. They should be fed more concentrates and green feeds with high protein content.
Strengthen the management of the early autumn and evening temperature difference, the rabbit is prone to illness, it is necessary to maintain the rabbit stable temperature. Close doors and windows at night and do cold work.
Do a good job of prevention of adult rabbits in the autumn should be injected to prevent rabbits, Pasteurellosis, Clostridium perfringens vaccine.
Doing a good job in storage Winter is relatively cold and there is a serious shortage of green feed. Therefore, preparations should be made early in the fall to make a good reserve of green feed.
