Feeding Management and Health Care of Growing Pigs
I. Feeding Management of Growing Pigs
(1) Physiological Characteristics of Growing Piglets
Growing piglets refer to piglets raised in the growing house after weaning, that is, from leaving the farrowing house until being moved out of the growing house, generally between 35 and 70 days of age, spending about 35 days in the growing house.
The physiological characteristics of growing piglets are:
1. Poor cold resistance: once growing piglets leave the warm farrowing house and the embrace of the sow, they need a period of adaptation, and are especially sensitive to temperature. If they live in an environment below 18 degrees C for a long time, it will not only affect their growth and development but also induce a variety of diseases. Carbon dioxide measuring instrument/carbon dioxide monitor, temperature and illuminance recorder/temperature and illuminance recorder, recorder/self-recording thermo-hygrometer.
2. Fast growth and development: during this period, piglets have a particularly strong appetite, often showing food-grabbing and overeating behavior, known as the piglet's peak feeding period. If feeding management is proper, piglets grow rapidly, and their body weight can double between 40 and 60 days of age; otherwise, diarrhea, edema disease, paratyphoid and many other diseases are likely to occur.
3. High susceptibility to diseases: due to weaning, they lose the protection of maternal antibodies, while their own active immunity has not yet been established or is not fully developed, making them highly susceptible to diseases such as transmissible gastroenteritis and atrophic rhinitis. Certain vertically transmitted infectious diseases such as swine fever and porcine pseudorabies may also break out during this period.
Key work points: adopt various methods to reduce the stress of piglet transfer, and start from feed transition, herd management, environmental control and vaccination to improve the production performance and economic benefits of the pigs at this stage.
(2): Preparatory work before pigs enter the growing house:
After the previous batch of piglets in this unit is moved out, promptly carry out a thorough cleanup of the unit (removing all "dangerous" items that are unnecessary and may cause harm to the pigs), washing (including feed boxes, slatted floors, windowsills, fans, ceilings, floors and various tools, washed until the original color is visible), and disinfection (following the principles of first cleaning, second washing, third disinfecting, fourth repairing, fifth fumigating, sixth leaving empty, seventh re-disinfecting, and eighth receiving pigs, thoroughly purifying and disinfecting), and after one week of empty-house purification, adjust the house environment (temperature, humidity, etc.) and prepare for receiving weaned pigs.
(3): Work after piglets are transferred into the growing house
1. Reasonable grouping: in order to improve the uniformity and consistency of piglets and ensure the smooth operation of the "all-in, all-out" process, starting from the transfer of piglets, reasonably group them according to breed, sex, physique, etc., and pay attention to observation to reduce the occurrence of fighting among piglets. For individual sick and weak pigs, raise them separately with special care.
2. Sanitation positioning: from the day piglets are transferred in, sanitation positioning work should be strengthened (this work is generally completed within 1-3 days after transfer, the earlier the better), so that each pen forms three designated areas: a feeding and drinking area, a resting area and a defecation area, thereby creating conditions for maintaining the house environment and herd management.
3. Environmental control: pay attention to ventilation and insulation. The room temperature of the growing house is generally controlled at 22-28 degrees C, and the humidity is controlled at 60-65%. Because there are many pigs and high density in the nursery house, a large amount of harmful gases (ammonia, carbon dioxide, etc.) can often be produced in cold seasons. Therefore, while keeping warm, ventilation should be done well to remove harmful gases and provide the pigs with a more comfortable growth and living environment.
4. Feed transition:
4.1 In order to reduce piglet stress caused by feed transition, it is recommended to use the following scheme for feed transition: feed creep feed (8199) from day 1 to day 7 after transfer; feed pelleted feed : piglet feed = 2:1 on days 8-9; feed pelleted feed : piglet feed = 1:1 on days 10-11; feed pelleted feed : piglet feed = 1:2 on days 12-14; after day 14, feed all piglet feed. In production, this can be flexibly adjusted according to the overall condition of the herd. For sick and weak pigs, the feeding of creep feed or the feed transition period can be appropriately extended, while for heavier and stronger piglets after transfer, the opposite can be done. This can regulate production costs and increase production benefits.
4.2 During the first week after entering the growing house, piglets should be restricted in feeding, eating only until 70-80% full, so that piglets experience both hunger and fullness. This can not only enhance digestive capacity but also maintain a strong appetite, and can effectively prevent the occurrence of edema disease and diarrheal diseases. Growing piglets should be provided with high-quality complete feed.
4.3 Reasonable feeding: according to the actual situation of the herd, appropriately add growth promoters or antibacterial drugs to the feed. Carry out drug prevention work. In addition, during the feeding process, appropriate trough cleaning should also be carried out according to actual conditions to ensure the quality of the feed in the trough.
5. Vaccination: carry out all immunization work promptly and accurately according to the immunization program, ensuring accurate disinfection of the injection site, sufficient immunization dose, one needle per pig, injection for every pig, and standardized operation, to ensure the immunization effect.
II. Health Care Work for Growing Pigs
Under the basic premise of adhering to "epidemic prevention first" and following the principle of "prevention primarily, treatment secondarily," the following health care and prevention work is carried out for the growing pig herd:
(1) Health care objectives:
A: Reduce various stresses at weaning.
B: Strengthen physique, improve immunity, and increase survival rate.
C: Prevent post-weaning multisystemic wasting syndrome.
D: Prevent diseases such as diarrhea and edema.
(2) Comprehensive health care measures
1. Environmental aspects:
Pay attention to ventilation and insulation. The room temperature of the growing house is generally controlled at 22-28 degrees C, and the humidity is controlled at 60-65%, providing the pigs with a clean, hygienic, dry and relatively comfortable production and living environment. (If they live in an unclean environment below 18 degrees C for a long time, it will not only affect their growth and development but also induce a variety of diseases.)
2. Feed aspects:
Provide growing pigs with high-quality complete compound feed. In addition, to reduce piglet stress caused by feed transition, properly manage the feed restriction of newly transferred piglets in the first week and the feed transition of piglets in the second week. In addition, appropriately adding some broad-spectrum antibiotics to the transition feed is also a very good measure for preventing digestive system, respiratory system and nervous system diseases caused by transfer and feed transition stress in piglets.
3. Disinfection and epidemic prevention aspects:
3.1 Disinfection work: for disinfection work in the growing stage, adopt the principle of carrying it out in sync with the farm area disinfection, that is, disinfecting every other day (carry out all-round three-dimensional spray disinfection of the growing house every Monday, Wednesday and Friday), and ensure the effective concentration of the disinfectant and spray density, etc. To avoid bacteria and viruses developing resistance to the disinfectant, adopt the principle of changing the disinfectant once a week.
3.2 Immunization work: carry out all immunization work promptly and accurately according to the established immunization program on the farm, ensuring accurate disinfection of the injection site, sufficient immunization dose, one needle per pig, injection for every pig, and standardized operation, to ensure the immunization effect.
3.3 Antibody monitoring work: strengthen antibody monitoring of the herd and promptly take targeted measures:
Persist in doing quarterly blood testing work, and according to the blood test results, adjust the farm's immunization program and preventive medication procedures at any time; gradually implement antibody monitoring for each batch, and according to the antibody monitoring results, gradually adjust the farm's immunization and preventive medication procedures; at the same time, carry out drug sensitivity tests, strengthen treatment and targeted preventive medication.
4. Deworming, fly control and rodent control aspects:
A: Deworming work:
Internal deworming: preferred drug ivermectin (or avermectin premix)
Treatment course and route of administration: deworm once each in spring and autumn every year, with two treatment courses each time, each course lasting one week, and the interval between the two courses being one week.
Environmental deworming: after each treatment course ends, use trichlorfon or pyrethroid insecticides to carry out deworming in the growing house
and disinfection.
B: Fly control and rodent control:
Fly control: Jieli 33, Qiangyingbijing
Implement year-round in the growing house according to the instructions of the fly-killing drugs used; at the same time, strengthen the cleaning and tidying of environmental sanitation, adhere to the disinfection system in the production area, and ensure a clean environment, which is also conducive to fly control work.
Rodent control: persist in year-round chemical rodent control work. At the same time, the farm's feeding personnel should also strengthen observation of rats. When situations such as increased rat density occur, promptly place rat poison to carry out rodent control work.
