In the pig farming industry, sow rearing is a crucial task that directly relates to the production efficiency and economic efficiency of pig farms. In addition to scientifically sound methods of operation, she and he need to have an in-depth understanding of the state of their health, their onset cycle and their environment. Now, let's look at how we're going to do this。
Preparatory work before seeding
1. Nutrition and health check-ups for pigs
Before seeding, it is first necessary to ensure that the mother is well nourished and that the feed is balanced to meet the special needs of her reproductive period. An initial assessment of the nutrition of the pigs can be made by observing their state, mental state and appetite. At the same time, comprehensive health checks, including tests of physiological indicators such as body temperature, breathing, heart rate, as well as vaccination and deworming, are required to ensure that the mother is healthy and free from disease。
Preparation and decontamination of tools
Tools such as vasectomy, disinfection, glass syringes, etc., needed for planting should be prepared well in advance and subjected to rigorous disinfection. In particular, vasectomies should be made to ensure that their surfaces are smooth and undamaged so as not to cause unnecessary harm to the mother pig during the planting process. The choice of disinfectant fluid is also important, as it is generally used as a disinfectant without irritation, and as a broad spectrum, such as potassium permanganate solution。
3. Selection and preparation of pigs
The selection of adult pigs of good quality, healthy and disease-free breeding is key to improving fertility and the quality of future generations. The quality of pigs has a direct impact on the success rate of plant formulation and on the productive performance of future generations. In selecting pigs, attention is paid to their genetic and productive properties, in addition to their physical characteristics, such as size and hair colour. At the same time, it is important to ensure that the pigs are well rested and energetic before planting, in order to improve the quality of their breeding。
Options for timing
The suitable breeding age for pigs is around 6-8 months and weighs about 90-100 kg. In the event of an ovulation of a pig during an ovulation period, two or three hours before the ovulation of the pig is generally chosen, which is the optimal rearing period. The ovulation cycle for pigs is typically 5-7 days, with an ovulation period of 2-3 days. The behaviour of pigs, such as reduced appetite, anxiety and climbing over other pigs, is carefully observed during periods of onset, and these are typical manifestations of sow onset. This should be done in a timely manner in order to increase the number of births。
Iii. Application methodology
1. Natural species
Natural formulation is the most traditional form of distribution and applies in the case of large pig farms with their own pigs. In the case of seeding, the pig shall first be driven to the mating point and then to the designated male. When the male climbs over the mother, the latter's tail bara can be turned to the side so that the penis can be successfully inserted into the vagina. In order to prevent the penetration of the penis into the anus, it is determined whether the pig ejaculates according to muscle fluctuations near the anus. Care should be taken to maintain environmental health and the quiet state of the mother pig during planting and to avoid the effects of stress on the effects of the formulation。
2. Artificial insemination
Artificial insemination, which is widely used in the modern pig farming industry, can increase the utilization of good pigs, reduce the number of heads raised by pigs, overcome the difficulties of doing business when male pigs are of very different sizes, avoid the spread of disease and solve the problem of semen needed for multiple plantings. In the case of artificial insemination, the mother shall first be kept quiet. They then wash their hands and disinfect the fertilizers and the vagina of the mother pig. The vasectomy is inserted into the cervix of the mother pig and is injected with semen with care to avoid damage to her uterus and urine. After the vasectomy is completed, the vasectomy is to be removed and the vagina of the mother pig is to be sterilized with disinfection. In order to increase the fertility rate, two integrations or multiple appliances can be used。
Iv. Care and observation after planting
The condition of the mother and the pregnancy of the mother are closely monitored for a period of time after the planting. A successful pig would not be incendiary if it were to fail. Care should also be taken to keep the pigs quiet so as to avoid the effects of stress on their fertility and health status. The proper feeding of the pig during a period of time after planting ensures a balanced diet to meet its reproductive needs. In addition, sterilization sites are regularly cleared to reduce opportunities for bacterial infection。
V. Notes
1. Avoid next-of-kin species: the next-of-kin species may lead to genetic defects or reduced reproductive performance in future generations, thus ensuring that the selected male and female pig is not related to blood to avoid procreation。
2. Be aware of the type of environment in which the mating grounds should be chosen to be far, quiet and flat from the corks to reduce outside interference. Indoor mating in the summer when the weather is bad, and in the morning and in the cold at night to avoid the effect of high temperatures on the effects of the blending。
3. Reasonable feed: during the graft period, the diet is adjusted to the mother's condition and age in order to avoid adverse effects on the graft effects of overweight or thinness。
4. Knowledge of the ovulation cycle: accurate control of the ovulation cycle of the mother is key to successful ovulation. In general, ovulation at its peak occurs two to three days after the onset of the sow's onset, and is effective in increasing the fertility rate。
Vi. Scientific soundments
1. Precision surveillance
Electronic induction monitoring systems, such as smart earmarks or wearable equipment, allow real-time monitoring of changes in physiological indicators such as the temperature, activity, etc. Of the mother pig, with accurate prediction of her onset and ovulation time. This technology not only increases the efficiency of distribution, but also reduces the subjectivity and error of artificial judgement。
Quality assessment of semen
Modern laboratory techniques allow detailed quality assessment of collected hog semen, including parameters such as sperm activity, density, morphology, etc., so that quality semen can be screened for artificial insemination. This has greatly improved the efficiency of the use of semen and the success of seeding。
3. Genetic optimization
A combination of genomics and molecular marker assistive selection techniques allows for genetic assessment of male and female pigs and the selection of individuals with excellent genetic characteristics for grafting. This has contributed to the rapid development of new varieties that respond to market demand, rapid growth and good meat quality。
Vii. Looking ahead
As technology continues to develop, sow horticulture will increasingly become intelligent, accurate and efficient. In the future, we are expected to see more applications of innovative technologies, such as robotic auxiliary seeding, remote surveillance and diagnostic systems, which will revolutionize the pig industry. At the same time, it is incumbent upon every practitioner to strengthen technical exchanges and cooperation within the industry in order to promote a greener, healthier and sustainable development of the pig industry。
In sum, the success of the sow-planting as an important part of the pig farming industry is directly related to the productivity and economic efficiency of the pig farms. Through the management of science, fine operation and technical assistance, we can continuously increase the success rate of sow-planting and contribute to the sustainable health development of the pig industry。
