Piglet purchase
Wu Guangwen said that first of all, the piglets must be selected for clearance. He said that, generally speaking, the piglets in the bazaar are miscellaneous and easy to carry, so it is advisable to go to the farm and strive to purchase varieties with good quality, disease-free and well-developed conditions at the lowest possible price. For piglets, it is advisable to choose dual or triple crossbred pigs of 30 kg or more as fattening objects for commercial pigs.
Immune deworming
Before pregnancy, prepare for immunization, deworming, gastric lavage, and stomach preparation. The piglets should be injected once in the field and injected once (four common swine fever vaccines should be injected once, and then seven days later, they should be injected with swine fever and one swine erysipelas. Deworming can be done with levamisole or albendazole tablets, fed at 25 mg per kilogram of pig body weight into the feed to drive off parasites. The surface of the pig was sprayed with 3%-5% trichlorfon solution to drive off the ectoparasites. With stomach, 2 tablets of rhubarb soda per 10 kilograms of body weight were mixed and fed into the feed three times.
Nutrition is appropriate
During the rearing period of the finishing pigs, we must pay attention to proper nutrition. It is best to divide the rearing period by 20-60 kg in the early stage of fattening and 60-110 kg in the later period. According to the nutritional needs of pigs, farmers can choose local feed resources and use enriched premix to feed the pigs with full-priced diets. The growth of pigs requires various nutrients, and the single feed is often not comprehensive enough to meet the requirements of pig growth and development. A variety of feed combinations can use the complementary functions of proteins and other nutrients to increase the digestibility and utilization of nutrients such as proteins.
Reduce feeding costs
Studies have shown that a single corn feed has a protein utilization rate of 51% and a single meat and bone meal of 41%. If two corns are added together with a bone meal of meat and bone, the protein utilization rate can be increased to 61%. The time and frequency of feeding the pigs each day should be fixed. This will not only make the pig's life regular, but also be conducive to the secretion of digestive juices and increase the pig's appetite and feed utilization.
When the concentrate is predominant, it can be fed 2-3 times a day. The amount of feed each day in a day can be roughly distributed at 35% in the morning, 25% at noon, and 40% in the evening; the pig farm with more green fodder is daily To increase 1-2 times. According to the appetite and growth stages of the pig, the amount of feed should be adjusted at any time. Each feed should be kept at 89%, so that the pig can maintain a strong appetite at each feeding. Feeding pigs on raw feed can save fuel, reduce expenses, and reduce feed costs. It is better to use a thicker ration for the diet, and the general feed ratio of 1:2.4 is appropriate.
Reasonable grouping
In the management of pigs, it is advisable to group well, and it is advisable to keep 10 to 20 heads in each lap, so as to ensure that each pig has a suitable field area: usually 0.6-1 square meter/head in the pre-fatation period and 1-1.5 squares in the later period. m/head, and should keep the weight of pigs in the same lap bar evenly. At the same time, it is necessary to do a good job of the “three-point positioning†of the pigs, so that the pigs can develop habits of defecation, feeding, and sleeping from the beginning.
Prevent excessive exercise
Wu Guangwen particularly reminded the pigs that during the fattening process, excessive movement should be prevented, especially fierce fighting or catch-up. Excessive exercise not only consumes energy in the body but, more seriously, it can easily cause pigs to suffer from a stress syndrome. Sudden emergence of paralysis, stiff limbs, and serious pig deaths occur.
Pay attention to seasonal stress
After entering the autumn, the decrease of temperature is the most important factor, so the temperature in the pig house should be controlled first. The most suitable temperature of the pig itself is 18°C-23°C. In this temperature range, the growth of pigs is relatively fast, but the temperature in the autumn pig house is generally lower than this range, and it is easy to cause cold stress. Therefore, the pigs should be kept warm. Conditions can use heating, infrared light bulbs, without conditions to use some measures such as covering plastic sheeting, cooking stoves, and finally keep the pig house at a suitable ambient temperature.
Pighouse insulation ventilation
While keeping the pig house warm, pay attention to strengthening ventilation and prevent air pollution. At the same time, to select ventilation when the temperature is high, generally speaking, 10:00 am to 4:00 pm is the best time for ventilation.
Master the timing of the slaughter
In order to pursue better economic benefits, farmers should also have a good grasp of the timing of slaughter, pay attention to the collection and control of information on pig raising, and determine the scale, direction, feed type, and slaughter weight of pigs based on information. When the weight of pigs grows from 110 kg to 200 kg, the daily gain gradually decreases. Therefore, slaughter is best when the pigs are raised to 110 kg body weight.
