How to induce heat-Recommended practices
*After farrowing, a sow may be slow to come into heat. Here are a few methods. used by farmers to induce heat
*Gently stroke the sow's vagina with a freshly cut papaya stalk every morning for 3-5 days.
*Spray the sow's (or gilt's) pen with boar urine every morning for 3-5 days.
*Grind 1 kg of fresh or dried lotus (Semen nelumbinis) seeds. Mix with 20 kg of dry feed. Feed to the sow twice a day for 5-7 days.
*Bring the sow to the boar, or place the sow in a pen next to the boar.
*Put the sow with the boar for a short period every day when the heat is expected.
*Always take the sow to the boar. This is less upsetting for him.
*Put the sow and boar together just before feeding.
*During her 24-hour pick heat period allow the boar to serve twice, with an interval of about 12-14 hour intervals between services. Do not mate animals during the hot time of day.
*If the sow doesn't conceive, she will return on heat again in about 3-week's time.
*10 days before service, give the sow/gilt 1-2 kg of feed extra per day. Continue this for one week after service.
*During the last month of pregnancy, give 0.5 kg extra feed per day but decrease this gradually one week before farrowing. Provide plenty of water to help prevent congested gut during farrowing.
*Each boar should be kept in its own pen to avoid fighting. For mating, the sow is taken to the boar.
Stimulating regular heat
*Remove the sow from the piglets early (at 4-6 weeks of age) and all at once.
*Take the sow to a house with dry sows.
*Put the sow close to a boar, in a way that makes direct contact (hear, see, smell) possible.
Conclusion on Selection of Breeding Gilt:It is extremely important to select a good boar since it contributes half the quality of the herd. Areas to be consider while selecting breeding Gilt:
*Gilts to be selected from sows, which wean 9-10 or more piglets per litter and are known to be good mothers and first farrowing at one year of age and farrowing interval of seven month.

Synchronization of Oestrus in Swine
Synchronization of oestrus is a reproductive management tool used to control the estrous cycle in sows, ensuring that they come into heat at the same time. This practice is particularly useful for improving breeding efficiency, enhancing herd productivity, and streamlining farm operations. By synchronizing estrus, farmers can optimize the timing of insemination, increase farrowing rates, and reduce the need for multiple boars.
1. Importance of Oestrus Synchronization
- Improved Breeding Efficiency: Synchronizing oestrus ensures that a group of sows comes into heat at the same time, allowing for more efficient use of boars or artificial insemination (AI) techniques.
- Optimal Timing for Insemination: With synchronized estrus, insemination can be scheduled more precisely, improving the chances of successful conception and reducing wasted semen.
- Labor Efficiency: Managing a group of sows coming into heat simultaneously reduces labor time spent on heat detection, making it easier to monitor the sow’s reproductive cycle.
- Increased Farrowing Rates: Synchronized estrus increases the likelihood of higher farrowing rates, as all sows are bred at the optimal time for fertilization.
- Better Herd Management: Oestrus synchronization helps manage the timing of farrowing, so piglets are born in clusters, making feeding and weaning more efficient.
2. Methods of Oestrus Synchronization
There are several methods of synchronizing oestrus in sows. These methods generally involve the use of hormonal treatments, which regulate the sow's reproductive cycle. Below are the most common methods:
2.1 Hormonal Treatments
Hormonal synchronization involves administering hormones to manipulate the estrous cycle. The most commonly used hormones for synchronization in pigs are:
- Progestagens: Progestagen-based products (e.g., Matrix®) are widely used to synchronize oestrus. Progestagens suppress estrus and can be used to bring sows into heat after withdrawal of the hormone. Typically, sows are fed progestagens for 18-20 days before the hormone is withdrawn, and estrus will occur within 4-7 days.
- PG600® (Pregnant Mare Serum Gonadotropin and Human Chorionic Gonadotropin): This combination of hormones stimulates the ovaries to induce estrus in pre-pubertal or anestrous sows. It is typically administered 1-2 days after weaning to induce estrus and optimize the chances of successful breeding.
- GnRH (Gonadotropin-releasing Hormone): GnRH can be used to stimulate ovulation and synchronize estrus. This hormone stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), triggering ovulation.
- Prostaglandins (PGF2α): Prostaglandins are used to synchronize estrus by causing luteolysis (breaking down of the corpus luteum), which induces estrus in sows that are in the luteal phase of their cycle. This method is often used in combination with other synchronization methods.
2.2 Weaning-Induced Estrus Synchronization
Weaning can induce estrus in sows, as the abrupt removal of piglets from the sow stimulates hormonal changes that cause estrus to begin within a few days. This is a natural method of synchronization, but it is less predictable than hormonal treatments. Typically, sows come into heat within 3-7 days after weaning, which makes the timing of breeding critical.
2.3 Combination Approaches
Some farms use a combination of hormonal treatments and weaning-induced synchronization. For example, PG600® may be used in combination with weaning to improve synchronization and increase the likelihood of successful conception.
3. Factors Influencing the Success of Oestrus Synchronization
- Sow Health: Healthy sows with good body condition are more likely to respond positively to synchronization treatments. Sows that are stressed or in poor health may not respond as effectively.
- Age and Parity: Younger sows (gilts) and older sows may have different responses to synchronization treatments. Gilts are often more responsive, while older sows may require a more tailored approach.
- Management Practices: Effective heat detection and optimal management of the farm are crucial for the success of synchronization programs. Timely insemination and proper handling of sows are key to maximizing pregnancy rates.
- Diet and Nutrition: Nutritional status can affect the reproductive system of sows. A balanced diet with adequate energy, protein, vitamins, and minerals is essential for maintaining reproductive health.
4. Challenges of Oestrus Synchronization in Swine
- Cost of Hormonal Treatments: While synchronization can improve farm productivity, the cost of purchasing hormones and related products can be high. Small-scale farms may find it difficult to afford the required treatments.
- Response Variability: Not all sows respond predictably to synchronization treatments, which can lead to inconsistent results. Genetic factors, health, and age can all influence the success rate.
- Increased Management Demands: Synchronization requires close monitoring of sows, including accurate timing for insemination and follow-up care. This can increase labor costs and demands on farm staff.
- Potential Health Risks: Overuse or improper use of synchronization treatments can lead to health risks such as hormonal imbalances, ovarian cysts, or infertility in sows.
Conclusion
Oestrus synchronization in swine offers significant advantages in terms of breeding efficiency, labor management, and herd productivity. Through the use of hormonal treatments and natural methods, farmers can effectively control the timing of estrus, leading to improved conception rates and higher farrowing productivity. While there are challenges associated with synchronization, such as cost and response variability, the practice remains a valuable tool for modern pig farming operations seeking to maximize efficiency and profitability.
