Management of Breeding Sow/Gilts in Piggery

HEAT DETECTION - COMMON SIGNS OF HEAT


1st Stage: Early heat signs

  • General restlessness.
  • Vulva turns red and is swollen.
  • White muscus discharge.

2nd Stage: Service period signs

  • Real Oestrus lasts for 40-60 hours.
  • Vulva becomes less red and swollen.
  • Slimy muscus discharge.
  • Tendency to mount and be mounted by others.
  • The sow or gilt will stand still when pressure is applied to her back ( can accept a men's weight sitting on her. Thus the right stage to send her to the boar).

3rd Stage: Post oestrus- period signs

  • The sow / gilt will not stand still when pressure is applied to her back.
  • The swelling of vulva disappears.


HOW TO INDUCE HEAT-RECOMMENDED PRACTICES

After farrowing, a sow may be slow to come in to 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 to 5 days.
  • Spray the sow's or gilt's pen with boar's urine every morning for 3 to 5 days.
  • Grind 1 kg of fresh dried Lotus seeds (Semen nelumbinis). Mix with 20 kg of dry feed. Feed to the sow twice a day for 5 to 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 everyday 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 Hrs. peak heat period allow the boar to serve twice, with an interval of about 12 to 14 Hrs 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 1to2 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 health prevent congested guts 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 to 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.
  • The sow should not be given any feed on the day of weaning.
  • The next day feed about 4 kg per day. This is called flushing and should be done for a maximum of 10 days or until the service takes place.
  • Put the sows in groups. (Stress stimulates heat)
  • If there are heat problems, change the type of feed for a few days.
  • Maintain a good climate; see to it that there is sufficient light in the house.
  • Sows should not be too fat or too thin when they are served. It is important to keep this in mind when determining the ration during the suckling period.

WHEN SOW IS IN GESTATION

  • After 21 days of serving she does not show any heat signs.
  • Echo scan pregnancy detection 23 to 35 days, positive results.

CULLING 

  • Sows that are difficult to get in -pig (Pregnant) which only manage to rear small litters should be sold off.
  • Boars which are infertile or moderately infertile should be culled.

BREEDING BEHAVIOR EXPRESSED DURING BREEDY PERIOD









ASSISTANCE

  • Young boars may need assistance in lining up their mate. Make sure your hands and wrists are clean and your finger nails are trimmed.
  • Pigs mate slowly. The boar may take a minute or more to reach the point of ejaculation.
  • To improve conception : Crush 1 kg of lotus seed and mix with the sow's feed. Give 2 times per day for 3 to 5 days.
  • Fat sows may have difficultly conceiving. Therefore, if a sow is too fat, reduce her feed.

REASONS FOR NOT CONCEIVING


  • The sow is too fat.
  • It is the animal's first heat cycle.
  • The boar is too young.
  • The boar is overworked (Used for more than 5 matings a week).

Any question/query is welcome.

All Type of Pig Feed Formula

प्रिय किसान भाइयो, जब आप रेडीमेड फीड बाहर से किसी डिस्ट्रीब्यूटर से लेते हैं तो कम से कम 1रु प्रति किलो का प्रॉफिट तो डिस्ट्रीब्यूटर रखता है और कम से कम 2 रु प्रति किलोग्राम का प्रॉफिट कंपनी भी रखती है और इसमें डिस्ट्रीब्यूटर तक फीड पहुचने का किराया भी कम से कम 1 रु प्रति किलोग्राम तो आता ही होगा , फिर उसके बाद आप भी कुछ किराया खर्च करते ही होंगे । अतः ..... अब किसी भी तरह की रेडीमेड पिग फीड लेने की जरुरत नहीं, आपका पैसा कीमती है, इसे बचायें। जितना एक्सट्रा पैसा फीड कम्पनियो को देते हैं , गरीबों में दान कर दें सुकून मिलेगा।  :) आजकल सबसे ज्यादा समस्या सूकर पालको को फीड की होती है , क्यूंकि सही और वैज्ञानिक आधार पर पिग फीड बनाना बहुत से किसान भाइयो को नहीं आता है और पुराने सफल पिग फार्मर अपनी फार्मूलेशन नहीं देते हैं। आज इसी समस्या को ख़त्म करने के लिए मैंने यहाँ पिग फीड बनाने के कई फॉर्मूले बताये हैं ,आप भी अब किसी रेडीमेड फीड कम्पनी को अपने हिस्से की प्रॉफिट के पैसे को देने से बच सकते हैं। ड्राई फीड  पिग फीड हमारे हिसाब से चार तरह की होती है। ब्रीडर फीड  ( ...

फीड सस्ती और ग्रोथ जबरदस्त

कैसे करें अपने पिग्स की अच्छी ग्रोथ  दोस्तों ,  आजकल देखा जा रहा है कि जितनी सफलता पिग फार्मर्स को मिलनी चाहिए उतनी सफलता किसानो को नहीं मिल पा रही है जिसके कई कारण हैं जैसे कि ... सही फीड फार्मूला का न मिल पाना।  फीड कंपनियां फीड की कीमत को लगातार बढ़ाते जा रही हैं और जो मुनाफा किसान को होना चाहिए उसका लगभग आधा या उससे अधिक मुनाफा फीड कम्पनियो की जेब में चला जाता है।  फेटनिंग के जानवरों को ब्रोकर सही कीमतों पर नहीं खरीदते , आज के समय में (जनवरी 2020) में जब फेटनिंग के जानवरो की कीमत 120 रु प्रति किलोग्राम (जीवित) है तब भी अधिकतम ब्रोकर / ट्रेडर ऐसे हैं जो ड्राई फीड बेस्ड जानवरो की कीमत 105 रु प्रति किलोग्राम से शुरू करते हैं।  जानवरों को सही तरीके से रखरखाव की व्यवस्था का न होना।    पिग फार्मर्स में एकता न होना।  परेशान किसान  स्वस्थ जानवर  अब आते हैं आज के मुद्दे पर , कि सही मुनाफा लेने के लिए किस तरह की व्यवस्था करी जाय जिससे सही समय में सही ग्रोथ हो और फीड की कीमत भी अनाप शनाप तरीके से न बढे। अच्छी बढ़वार क...
