In the production of breeding pigs, there are still some small-scale farmers, the level of feeding and management is relatively low, and the production technology is relatively backward. The author talks about the problems in the breeding and management of “lean-type†breeding pigs and piglets for the problems existing in breeding pig farmers. Some points.
I. Breeding and management of breeding pigs
1. Breeding management of breeding boars
A boar should have sufficient light, ventilation, clean and dry conditions, and have a place to exercise.
2 Boars can start breeding eight months, the number of breeding, young boar 2 times a day, 8 times a week, 25 times per month is appropriate; adult boars mix 3 times a day, 12 times a week, 40 per month The second is appropriate. After 4-5 days of continuous breeding, it is necessary to rest for 1-2 days to restore boar physical strength.
3 The boar must have enough vitamins for its daily feed, especially enough vitamin E. When the species is busy, provide enough nutrients to mix nutrients such as eggs in the feed.
2. Breeding and management of breeding sows
A sow house delivery room needs to be kept clean and dry. The sow should be kept dry and clean after delivery. The conditional delivery room should be provided with a high bed, and there should be no high bed delivery room. Clean the room frequently, avoid flushing with water, and tow when the ground is wet. Dry, and padding and other bedding.
2Feed varieties: After mating to 107 days of pregnancy, feed gestational material; 108 days of pregnancy until breastfeeding before mating.
Feeding amount: The sow was fed a suitable amount of feed by conception until 80 days of pregnancy; the feeding amount was increased from the 80th to the 107th day of pregnancy; the feeding amount was gradually decreased from the 108th day of pregnancy to the tiller, and was reduced to 0.5 kg on the 1st day of the delivery. On the day of delivery, it is best to feed about half a kilogram of bran and feed 0.5 kilograms of mixed feed. On the 4th day after delivery, gradually increase the amount of feed. Take the example of the sows that produce 10 pigs and postpartum For 8 days, the feeding amount for one day should be increased to 6 kg (2 kg for sows and 0.4 kg for each piglet), and the feed amount should be kept until the piglet is weaned. The amount of feed should be controlled so that the weight of the sow at the time of weaning is not less than 70% of the body weight of the sow when it enters the room.
For lean sows (when the body weight is less than 70% of the pre-natal weight), the amount of feed must be increased from weaning to breeding, and the energy and protein levels must be increased in the diet to restore the sows’ Constitution, so that the sows can estrus mating.
3 management of childbirth.
Production preparation: First, the delivery room should be kept clean and dry, and the ambient temperature must be controlled between 15°C and 27°C. Secondly, prepare the iodine spill, towels, and children and scales for production; .
Confidence: After the piglets have been produced, dry their nose and mouth and body mucus with a sterilized dry towel, then cut the umbilical cord and apply iodine to the cut end of the umbilical cord. After the sow has been delivered for several days, the breast is scrubbed with warm water of about 40°C.
4 Breeding: Sows are generally bred after the weaned pig is weaned one week later.
Second, feeding and management of piglets
1 Temperature: Piglets should be grown at 21°C-27°C before weaning. Insufficient temperature should be added with infrared lamp insulation.
2 The environment in which the piglets live should be kept clean and dry. There is no condition to set up a high-level nursery. Clean the dry linen on the place where the piglets rest.
3 When the sow is giving birth, she is allowed to suck colostrum immediately after each delivery and assist the newborn pig to eat enough colostrum so that the piglet can obtain maternal antibodies.
4 Broken tail, broken teeth: In the 25th hour after delivery, the piglet is the best time for breaking the tail and breaking the teeth. The tail is broken to one-third, leaving two-thirds.
5 Open food: Adopt active food-feeding measures. When the piglets are 5 days old, they will be taught into a paste, wipe some of them into the mouth of piglet until 9 days old, and gradually feed the crepe material after 7 days of age. .
6 Weaning: The piglet can weigh up to 6 kg and the piglets can be weaned between 21 days and 28 days.
7 Keeping in the nursery period: When the piglet is weaned, it is best to remove the sow and allow the piglet to be kept in the original room for one week before moving the piglet to the nursery. The piglets were fed 35 days of feeding and they were able to switch to feeding milk and 50 days to feed the piglets. Pay attention to the gradual change of feed conversion.
8 The design of nursery houses and small pig houses is best equipped with two water supply systems, one for the usual drinking water system and the other for the drug delivery system. The pig's taste is more sensitive. Therefore, it is advisable for the pig to take medicine. It is best to add drinking water so as not to mix the medicine with the feed and reduce the palatability. In addition, the nursery house and the pig house should not be designed with a foot window to prevent the thieves from making the wind. Cool.
As mentioned above, some small-scale farms often ignore management. Reasonable feeding and management, a good health environment, and comprehensive preventive measures are the key to raising a good breed of pigs and piglets.
