Introduction: Most farmers in the past will raise a few pigs, to the New Year’s time to kill to eat, but some farmers will specialize in raising more pigs to sell meat to make money, if you want to earn more, raise a good sow is very necessary. So how can you raise a good sow? I’ll tell you about it below.
The technical points of raising good sows:
1、choose sows
Introduction of the best selection of 50-70 kg pigs, in addition to the breed, the selection of sows require a healthy body, long body size, large physique, wide front chest, wide back hip, wide legs, high body length to be flat or slightly wide, nipple alignment neat, prominent and obvious, effective nipples in more than 7 pairs, the reproductive system has no defects in the pigs.
2、Rearing management of reserve pigs
Once as a reserve pig, feeding should be reasonable, the fat should not be too fat or too thin, and the nutrition should be moderate. From 70 kilograms after the beginning of feeding restrictions, daily control in 5 pounds of material. Most of the reserve pigs in 160 pounds or so start the first heat, after the heat breeding to follow the old with early, less with late, not old, not less with the principle of the middle. Feeding to follow the “three high, three low” nutritional principles, namely, after heat, breeding 4 ~ 70 days after delivery, let the pig eat better; 0 ~ 4 days after breeding, breeding 70 ~ 90 days after delivery, 90 ~ 114 days before feeding less.
3、Provide quiet and comfortable living environment for sows
Disinfect the sow enclosure before farrowing, take heat preservation measures in winter, relieve heat and cool down in summer, it is best to keep the sow enclosure at 18~20 degrees.
4、Timely weaning
Weaning of piglets should not be late but early, around 30 days old is the most suitable. Too long breastfeeding time will affect sow’s body recovery and production times; too short breastfeeding time, piglets have poor body quality, high morbidity and mortality rate. Weaning time should be combined with the condition of piglets, generally weaned piglets at about 6 kilograms.
5、Do a good job in preventing sows from disease
At present, the infectious diseases that affect the performance of sows are especially many, and the development of a reasonable immunization program can effectively reduce the morbidity rate and avoid the occurrence of low farrowing rate, stillbirth and other diseases. Reasonable immunization program not only reduces the morbidity rate, reduces the cost, but also indirectly prolongs the service life of sows. Immunization program should be based on the situation of pig farms and local epidemic diseases, not a rigid set.
6、Prevent feed mold
Mycotoxins mainly attack the reproductive system, which can lead to false heat or even no heat, abortion and stillbirth, etc. It is recommended to add quick-acting mold removal king.
