The key control point for swine batch production
The pig batch production model refers to the early industrialized batch production model, and gradually changes into a batch production model for pigs and other livestock in practical applications. This model utilizes a full-in, full-out production method, in which the pigs in the same batch of pigs are kept together at the production stage or at the same age, and they are transferred or slaughtered in the same batch, so that the pig's health status and production performance (gains Speed, feed compensation, and market age, etc. are kept at an optimal level. The traditional mode of production cannot achieve all-in and full-out, and the batch production mode can block the spread of disease caused by traditional continuous feeding methods. The pig production management adopts all-in and all-out feeding methods. Although all production stages are in the same farm, batch production is implemented. Different batches of pigs are not polyculture, and each pighouse or unit is fed with one. For pigs, pigs can be produced in batches of one week, two weeks, three weeks, or five weeks depending on the size of the farm, and isolation and epidemic prevention measures must be strictly enforced between individual pig houses or units. Pigs in different stages of production (eg, mating gestation, parturition and breastfeeding, piglet nursery, growth and finishing, etc.) are each in different pig houses or units, and all-in and all-out methods can block epidemics among pigs. The level of infection. The point-based breeding mode used in modern large-scale pig production can achieve batch and full-entry and full-out production, minimizing the risk of pig biosecurity. The key control points for swine batch production: 1. Sow estrus breeding control point If gilts and boring sows are improperly reared and managed, they cannot be estrus at a predetermined time; on the contrary, if estrus is out of control, the possibility of too many pregnant sows will increase, both of which will affect Realization of batch production goals. Therefore, the estrus breeding of sows is the most important key control point, which requires the production plan of breeding target in advance. With regard to the use of gilts, after the breeding work is completed this week, according to the number of breeding stocks in this batch, it can be predicted how many reserve pigs will be needed for the batch of pigs after 20 weeks to supplement them, and prepare the pigs in advance. Introduction or retention plan. Three weeks before the replacement of the spare pigs, gilts were treated with simultaneous estrus measures to meet the weekly batch breeding program. 2. Number of bifurcation beds and farrowing houses The number of tillers and farrowing houses determines the number of sow herds in each batch, and also relates to the number of herds in the breeding herd. There should be significant isolation and feeding measures for the different batches of farrowing houses. In addition, it is necessary to arrange a delivery plan for at least 12 weeks, and to arrange the turnover of the delivery room according to the actual situation, as well as the turnover of downstream care. 3. Timely adjustment of delivery rate The mating rates of different pig farms are not the same, and the results in winter and summer are also different. Therefore, the number of breedings for each batch of sows should be determined according to the mating rate of different breeding farms and different seasons, so as to meet the equipment demand for delivery (best bed for delivery). When the production performance is stable and the delivery rate is high, The number of breeding heads in this batch can be appropriately reduced, but otherwise the number of breeding heads in this batch should be increased. 4. Boar utilization The implementation of the batch production model will reduce the demand for breeding boars. Therefore, if it is a group of pig-raising companies, it may consider the construction of shared boar stations, centralized breeding of excellent boars, and artificial insemination; If it is a single medium and small-scale pig farm, it can be considered to rely on regional boar stations to carry out artificial insemination. Artificial insemination technology is an indispensable technology in the batch production of pig farms, and its technology is mature and worthy of promotion. If the condition is available, deep insemination techniques such as uterine body insemination (IUI) and uterine horn insemination (DUI) may be used in the artificial insemination, and compared with the conventional cervical insemination method (ICI). In comparison, each sow's insemination dose can be reduced from 3 billion sperm to 1 billion to 1.5 billion sperm (IUI) and 150 million to 200 million sperm (DUI), which can significantly increase boar utilization. 5. Statistics work After the implementation of batch production, in order to ensure the orderly and stable production order, it is necessary to have reliable production data as a support, otherwise it will completely disrupt the operation plan. For this reason, large-scale pig farms need to use production management software (such as Herdsman software, etc.) for data management, convenient and efficient. Many production data can be integrated after entering, and daily, weekly, monthly, quarterly, annual pig production indicators and production per head can be derived. Only by mastering the situation of each pig can we better do a batch production plan.
