Feeding Management and Health Care of breeding Pigs

Feeding management and health care of bred pigs (1) physiological characteristics of bred piglets refers to the piglets raised in the breeding house after weaning, that is, from leaving the delivery room to moving out of the breeding house, generally between 35 and 70 days old, about 35 days in the breeding house. The physiological characteristics of bred piglets are as follows: 1. Poor cold resistance: once bred piglets leave the warm room and the arms of sows, they must have an adaptive process, especially sensitive to temperature. If they live in an environment below 18 ℃ for a long time, it will not only affect their growth and development, but also induce a variety of diseases. Carbon dioxide meter / carbon dioxide monitor, temperature illuminance recorder / temperature illuminance recorder, recorder / self-recording temperature and hygrometer. 2. Rapid growth and development: during this period, piglets have a particularly strong appetite, often showing the phenomenon of rush to eat and gluttony, which is called the prosperous eating period of piglets. If the piglets are fed and managed properly, the piglets will grow rapidly and their body weight can be doubled between 40 and 60 days of age. Otherwise, it is prone to diarrhea, edema, paratyphoid and other diseases. 3. High susceptibility to diseases: the protection of maternal antibodies has been lost due to weaning, and their own active immunity has not been established or not perfect, and they are very susceptible to diseases such as transmissible gastroenteritis and atrophic rhinitis. Some vertical infectious diseases such as classical swine fever and swine pseudorabies may also break out in this period. Main points of work: take various methods to reduce the transition stress of piglets, and improve the production performance and economic benefits of pigs from the aspects of excessive feed, pig herd management, environmental control and vaccination. (2) preparation work before breeding pigs: after the last batch of piglets in this unit are transferred out Clean this unit thoroughly in time (remove all unnecessary and "dangerous" items that may cause harm to pigs), wash (including material boxes, net beds, windowsills, fans, ceilings, floors and all kinds of appliances), disinfect (in line with the principles of one cleaning, two flushing, three elimination, four repairs, five fumigation, six emptiness, seven re-elimination, eight pick up pigs, thoroughly purify and disinfect) After a week of empty house purification, adjust the environment (temperature, humidity, etc.) and be ready to cut off the suckling pig. (3): the work of piglets after being transferred to the breeding house 1. Reasonable grouping: in order to improve the uniformity of piglets and ensure the smooth operation of the technological process of "all in and all out", from the beginning of piglet transfer, reasonable grouping should be carried out according to their breed, male and female, physique, etc., and pay attention to observation, so as to reduce the occurrence of piglet struggle, as long as individual sick and weak pigs are raised separately and given special care. 2. Hygienic positioning: the hygienic positioning work should be strengthened from the date of piglet transfer (this work is usually completed within 1-3 days, the earlier the better), so that each column forms the positioning of three areas: drinking area, rest area and defecation area. so as to create conditions for maintaining the environment in the house and pig herd management. 3. Environmental control: pay attention to ventilation and heat preservation. The room temperature of the breeding house is generally controlled at 22-28oC and the humidity is controlled at 60-65%. Due to the large number of pigs in the nursery and high density, a large number of harmful gases (ammonia, carbon dioxide, etc.) are often produced in the cold season, so it is necessary to do a good job of ventilation and remove harmful gases at the same time, so as to provide a more comfortable growth and living environment for pigs. 4. Excessive feed: 4.1 in order to reduce the stress of piglets caused by excessive feed, the following programs are recommended: piglets are fed with suckling feed 1-7 days after transfer (8199); 8-9 days fed with pellet feed: piglet feed = 21gluten feed for 10-11 days: piglet feed = 1Ru 1maiting for 12-14 days: all piglets are fed with piglet feed after 14 days. In the production, it can be flexibly controlled according to the overall situation of the pig herd, and the time of feeding suckling pig feed or excessive feed can be appropriately prolonged for sick and weak pigs, and vice versa for piglets with larger body weight and strong body weight. In this way, the production cost can be regulated to increase production efficiency. 4.2 within the first week of entering the breeding house, piglets should be fed only 70% to 80% full, which can not only enhance digestive ability, but also maintain exuberant appetite, and can effectively prevent the occurrence of edema disease and diarrhoeal diseases. High-quality full-price feed is required for adult piglets. 4.3 rational feeding: according to the actual situation of pigs, growth promoters or antibiotics should be added to the feed as appropriate. Carry out drug prevention work. In addition, the proper cleaning trough should be carried out according to the actual situation in the feeding process to ensure the quality of the feed in the trough. 5. Vaccination: according to the immune procedure, all kinds of immune work should be done timely and accurately, so that the disinfection of the injection site is accurate, and the immune dose should be sufficient, one injection per pig, head injection, and standard operation to ensure the immune effect. 2. on the basic premise of "epidemic prevention first" and in line with the principle of "prevention first and treatment as a supplement", the health care work of breeding pigs is as follows: (1) Health care goal: a: reduce all kinds of stress during weaning. B: strengthen the physique, improve the immunity and improve the survival rate. C: prevention of multiple system failure syndrome after weaning. D: prevent diarrhea, edema and other diseases. (2) Comprehensive health care measures 1, environmental aspects: pay attention to ventilation and heat preservation, the room temperature of the breeding house is generally controlled at 22-28oC, and the humidity is controlled at 60-65%, so as to provide a clean, dry and comfortable production and living environment for pigs. (if you live in an unclean environment below 18 ℃ for a long time, it will not only affect its growth and development, but also induce a variety of diseases.) 2, feed: provide high-quality full-price compound feed for growing pigs, in addition, in order to reduce piglet stress caused by excessive feed, grasp the feed restrictions of newly transferred piglets in the first week and feed overwork in the second week. In addition, the proper addition of some broad-spectrum antibiotics to excessive feed is also a good measure to prevent digestive system, respiratory system and nervous system diseases caused by conversion and excessive feed stress in piglets. 3. Disinfection and epidemic prevention: 3.1 Disinfection: the disinfection work of the breeding section shall be carried out at the same time as the disinfection of the field area, that is, the principle of disinfection once every other day (omni-directional three-dimensional spray disinfection shall be carried out on Mondays, Wednesdays and Fridays) and ensure the effective concentration and spray density of disinfectants, etc., in order to avoid drug resistance of bacteria to disinfectants, adopt the principle of replacing one kind of disinfectant every week. 3.2 immune work: according to the established immunization procedures in the field, we should timely and accurately do all kinds of immune work, so that the disinfection of the injection site is accurate, and the immune dose should be sufficient, one injection per pig, head injection, and standard operation to ensure the immune effect. 3.3 Antibody monitoring: strengthen the antibody monitoring of pigs and take timely measures: persist in doing a good job of quarterly blood tests, and adjust the immunization procedures and preventive medication procedures in the field at any time according to the blood test results; gradually implement each batch of antibody monitoring, and gradually adjust the rules of immunization and preventive drug use in the field according to the results of antibody monitoring; at the same time, carry out drug sensitivity test, strengthen treatment and targeted preventive medication. 4, deworming, fly killing, rodent killing: a: deworming work: in vivo deworming: the first choice of drug ivermectin (or avermectin premix) course of treatment and administration: once a year in spring and autumn, two courses of treatment, one week for each course, and the interval between the two courses is one week. Environmental pest control: disinfect the breeding house with trichlorfon or pyrethroid insecticides after each course of treatment. B: killing flies, killing rats: killing flies: Jieli 33, Qiangying will be carried out all the year round in the house, according to the instructions for the use of fly-killing drugs used; at the same time, strengthen the cleaning and arrangement of environmental hygiene, and adhere to the disinfection system in the production area. ensuring a clean environment is also conducive to the development of fly control. Rodent control: adhere to the perennial implementation of drug anti-rodent work, at the same time, the field breeders should also strengthen the observation of rats, when there is an increase in rat density, timely administration of rodent poison to carry out rodent control work. -- hehe, study. Thank you, landlord.
