Piglets are piglets from the primary to the weaning stage and are the most basic and critical link in the pig industry. However, due to the unique growth and developmental characteristics and physiological characteristics of suckling pigs, environmental stress, nutritional stress, and immune organ development often occur. Mature and other multiple stresses cause it to be sick and the mortality rate is as high as 10% to 20%. Therefore, it is very important to raise suckling pigs. According to the practice of raising pigs for many years, the feeding and management of suckling pigs is reflected in the need to make a good "three levels", that is, the first birth, the supplementary feed, and the weaning pass.
l put a good birth
L.1 Wipe, cut umbilicus, cut teeth, break tail
After the piglet is born, the breeder should first export the nasal mucus so that the suckling pig can breathe frequently, and wipe the mucus of the body with a rag. Then cut off the umbilical cord, and first squeeze the coffee in the umbilical cord to the abdominal cavity of the suckling pig, and cut off the umbilical cord at 4 cm from the abdomen. If the bleeding is heavy, perform ligation and sterilize the iodine in the broken state. Then we must cut the teeth, that is to say, the hounds of the hounds of the sucking pigs should be cut off, and the cutting forceps must be disinfected with iodine beforehand. Broken tail is an effective way to prevent pigs from biting the tail. The suckling pig should be tailed within 3 days after birth and should be 3 to 4 cm away from the tail. The above measures must be standardized and strictly sterilized. This is an effective measure to reduce tetanus, streptococcal infections, and omphalitis causing umbilical hernias.
1.2 fixed nipple, eat enough colostrum
Colostrum is light yellow milk secreted by the pig 3 days after delivery. The importance of colostrum is that it contains a high amount of immunoglobulin which can be completely absorbed. The suckling pigs can produce immunity after sucking colostrum, thereby increasing the survival rate. After all of the suckling pigs are born, the sow's nipples should be thoroughly cleaned, and all the suckling pigs should be given enough colostrum. The suckling pigs have a habit of fixing the teats. By helping to fix the nipples manually, the piglets can be improved in shoe homogeneity and reduce death. Generally, the weak suckling pig is fixed in the front nipple, and the strong suckling pig is fixed in the back nipple.
1.3 iron supplement selenium
Insufficient storage of iron in suckling pigs can easily cause anemia, diarrhea, stagnation, and death in suckling pigs. Suckling pigs need 5 to 10 mg of iron per day, and only get iron lmg from breast milk every day. Therefore, 150 to 200 mg of iron should be added during breast-feeding to prevent anemia. Usually born within 3 days of age iron supplement, intramuscular l ~ 2ml blood or other iron agent preparations. The individual lean suckling pigs were injected again at 10 days of age. For selenium-deficient piglets, selenium should be supplemented within 3 days of age, intramuscular injection of 0.1% sodium selenite 1ml, and supplemented once at 15 days of age.
L.4 cold insulation
The suckling pig has the physiological characteristics of poor body temperature regulation and cold, and should pay attention to cold insulation. The delivery room temperature is best kept between 18 and 22°C, and the humidity is between 65% and 75% so that the sows will be farrowed in the delivery room. The newly born suckling pigs are allowed to rest in the incubator. Infrared lamps or electric heating plates can be used for insulation. . The optimum growth temperature was 35°C in the first week, 3l°C in the second week, 27°C in the third week, 25°C in the fourth week, and 21°C in the fifth week. Gradually adjust the indoor temperature to ensure healthy growth of piglets and reduce deaths. Good insulation can reduce the stress and diarrhoea of ​​suckling pigs and increase the survival rate and body weight of suckling pigs at weaning.
1.5 Other aspects
The production should be kept clean and regularly disinfected. In order to prevent the sow from pressing on the suckling pig, a sow limiter can be set up to castrate the boars around the age of 20 days and timely inoculate the swine fever and piglet paratyphoid. Sometimes according to the actual situation, the newborn pigs are weighed and weighed together, and the weak ones are sorted into sow litters with good lactation performance. Before the nests, sufficient colostrum must be eaten.
2 Scientific Feed Off
2.1 Feeding Objectives and Benefits
The feed supplements the sow's lactating small foot, increases the weaning weight, increases the production efficiency, stimulates the secretion of digestive enzymes, strengthens the adaptability of the suckling pig to the solid feed before weaning, exercises the digestive organs and functions of the suckling pig, and promotes the stomach. Intestinal development prevents diarrhea and reduces stress.
2.2 how to feed better
2.2.l feed start time and feed selection
Generally, 3 days after birth, supplies of clean drinking water are started. After 7 days of age, feeding programs for suckling pigs can be implemented. The feed should be selected as a pig feed material with good palatability, easy digestion and absorption, strong milk flavor and strong disease resistance. Especially the 7-15 day age is the most critical, and can gradually reduce the point of feed requirements.
2.2.2 Choosing the Right Feeding Method
The most important thing is to write an article around the word “lurking.†The principle of eating a small amount of food during the lure is not suitable for use as lure or overnight material. Generally used to induce lure method, refers to the training of suckling pig food, the piglet material should be soaked or add a little sugar, and then select the active sucking pigs, wipe the mouth, once learned to eat food, you can drive other suckling pigs. If 20-day-old piglets are still unwilling to eat food, they can reduce their lactating sows by 1 to 2 tons, so that the amount of milk in the sows will be reduced, and the feed for suckling pigs will be promoted.
3 early weaning off,
3.l purpose and significance of early weaning
Early weaning can increase the utilization rate and breeding rate of breeding pigs, ensure the uniformity of piglets, reduce the disease of piglets and increase the profit of pig raising.
3.2 Be scientific in early weaning
3.2.1 Pre-weaning time requirements and precautions
Piglets are already accustomed to feed and do not need to be weaned when they are breastfeeding. During the weaning period, depending on the piglet development, sow health status, feeding management level, and season, professional rearing is usually around the age of 25 days. It is recommended that rural pig farmers be suitable around the age of 30 days. One week before weaning, the sow’s drinking water and feed volume should gradually decrease, resulting in a reduction of anaplasia. Weaning is best done in the morning, while keeping the piglets in the original environment for 1 week to reduce stress. Weaning pigs should be provided with high-quality, full-price feeds after weaning to ensure adequate clean drinking water and reduce disease transmission opportunities.
3.2.2 Choosing the right weaning method
One-time weaning method, after the adoption of dietary training for well-developed piglets, weaning can be performed once-through, batch weaning method, according to the development and use of suckling pigs, successive batches of weaning in batches; gradually Weaning method, on the first day of weaning, suckling pigs were sucked 4 to 5 times, on the 2nd day it was 3 to 4 times, and then decreased day by day, after 4 to 5 days from the sow. During weaning, a single sow with good milking performance can continue breast-feeding for individual thin and thin piglets. After rejuvenation, weaning can reduce piglet death. When pigs are raised, they can be flexibly used according to actual conditions and needs.
The period of suckling pigs is about 1 month, and the time is very short. However, it is critical to the survival of piglets and must be given sufficient attention. Only by making the suckling pigs “close†can the pigs be successful.
