Pig farmers must see: piglets prenatal preparation and feeding management techniques
Farmers who want to get more benefits and reduce the mortality rate of sow pigs must be fully prepared before the sows are produced and fed after the pigs are born. Many farmers do not have the relevant knowledge or pay enough attention to the production of piglets for sows, resulting in a very low survival rate. This is a big economic loss for hog farmers. Therefore, reasonable feeding management technology is particularly important. Only when piglets grow up healthily can they improve the economic benefits of farmers.
First, adequate preparation before delivery
Large pig farms need to plan for batch delivery in batches. This method not only facilitates feeding and nesting of piglets, but also facilitates piglet grouping and is supported by multiple sows, thereby effectively improving the survival rate of piglets. Feeding managers need to disinfect the sow's nipple and surrounding skin, bed and pig incubator multiple times before delivery. Because the piglets are weak after birth, they are easily affected by pathogens. The whole pregnancy process of the sow needs to go through about 114 days. The nurses need to prepare for the labor and set the corresponding insulation measures 2 days before the sow is in labor. On the day of childbirth, the sow is given a small amount of food or stopped feeding. The main purpose of this is to prevent the sow from eating too much and adversely affecting the litter.
Second, careful delivery
The breeding manager must visit the site when the sow is in production. After the birth of the piglet, it is necessary to remove the mucus in the mouth and nose of the piglet with a towel in time, so that the piglet can breathe freely. Then apply the disinfected towel to wipe the pig's body. In the process of receiving the production, the management personnel need to pay attention to the umbilical cord should not be too early, the umbilical cord time is best after the piglet is born for 10 minutes to avoid excessive blood loss. After the piglets have broken the umbilicus, they need to be placed in a pre-prepared wooden box or a cardboard box to keep the piglets warm. If the breeding manager finds that there is a suspended animation in the piglet, you can apply alcohol or other irritants to the nose of the piglet, or use acupuncture to stimulate the piglet and treat the piglets in a state of suspended animation. The nursing work of the sows during the first few days of delivery is very important. The breeding management personnel must raise the level of attention and do a good job in moisture prevention and heat preservation of the living environment of the sows. After the sows are born, they need to do post-natal care work, strengthen the sow's intake of nutrients, so that the sow's physique can be restored as soon as possible to avoid postpartum infection.
Third, early colostrum, eat colostrum
Colostrum feeding can enhance the physique of piglets, enhance the resistance of piglets to various diseases, and improve the survival rate of piglets. Colostrum is the yellowish color of the sow within 5 to 10 days after delivery. This milk is very different from the chemical composition of ordinary milk. The protein content of colostrum is very rich, and it also contains a lot of vitamins and immunoglobulins. The intake of colostrum can promote the intestinal peristalsis of piglets, and can greatly improve the physical strength and heat production capacity of piglets. Therefore, the feeding manager needs to feed the colostrum within 0.5 hours after the piglet is born, and help the piglet find the sow's teat. Each piglet needs to consume more than 50 ml of colostrum. If the piglet's physique is weak or the piglet is rescued from the suspended state, it is necessary to adopt artificial assistance to improve the piglet's physical strength in a short time. , do a good job of water supply.
Fourth, clever foster care and nest
When the newly born piglets are raised and raised, the feeding managers must ensure the safety of foster care. Because the pig's sense of smell is very sensitive, they can correctly identify which piglet is born of their own, which piglet is not born by themselves, and will bite the foster piglet after identification. Therefore, in the process of fostering and nesting, the foster piglets must have the same odor characteristics as the piglets born to the foster sows, and the date of birth cannot differ by more than 5 days. When the first born piglets are placed in the post-born piglets for foster care, the feeding managers need to choose the smaller ones in the piglets. On the contrary, you should choose a larger size. There is also a certain requirement for sows in foster care, that is, the sow emulsion is well secreted, temperate, strong and has good antiviral ability. Foster pigs must be eaten in order to ensure a higher survival rate of foster piglets. Under the influence of special factors, the foster pigs do not have the colostrum of the raw mother, and can be replaced by the colostrum of the foster mother. In order to ensure that the foster piglets have the same odor as the piglets born to the foster mother, they can change their foster piglets and foster piglets for about 2 weeks, so that the scent of the two is close.
5. Prevent sows from attacking or crushing piglets
The primiparous sows sometimes bite the piglets or attack the piglets. The sows may also produce killing behavior when they are stressed. Therefore, there should be special personnel for feeding management, and try to avoid the stress factors such as the sows being frightened. In addition, the sows with poor motherhood or the old and cumbersome sows are easy to crush the piglets when they are lying down. Therefore, a nursing pen and a local incubator should be set up. When the sows walk or lie down, the piglets can run into the nursery. The barn avoids crushing, and when the piglets are finished, they can go to the local incubator for activity and rest.
As long as the farmers do the above five points, they can effectively improve the survival rate of piglets and greatly reduce unnecessary losses.
