Breeding techniques of piglets

In order to enable sow farmers to fully master piglet breeding technology, improve the survival rate and weaning litter weight of newborn piglets, and really get better benefits from sow feeding and piglet breeding, the demonstration households of pig farming were given serious guidance: from the feeding of sows to the nursing of newborn piglets, from the feeding and feeding of piglets to castration and epidemic prevention of piglets.

? First, do a good job in sow feeding.

The reserve sows can be raised as fat pigs, mated at the age of 8 months, and then decided to stay or be eliminated after the first birth.

1. Feeding principle: ① has high lactation and low pregnancy. During pregnancy according to the general fattening pig feeding, lactation period should be specially fed some. ② high-low-high feeding method. In the first month of pregnancy, it is necessary to feed close to and after giving birth, and feed fattening pigs in the middle of pregnancy. Pregnant sows with good fat water should be fed less 5 days before and after delivery, which can prevent lactating sows from postpartum anorexia.

2. Sow feed formula

(1) pregnant sows: Baogu 40%, broad bean (fried) 4%, soybean (fried) 3%, rice bran 25%, rapeseed cake 7%, wheat bran 22%, bone meal 2%, salt 0.4%, Kunxing brand additive 0.2%.

(2) Breastfeeding mother brazing formula: Baogu 40%, wheat 17%, broad bean (fried) 5%, rice bran or wheat bran 21%, rapeseed cake 15%, bone meal 2%, salt 0.5%, Kunxing brand additive 0.2%.

3. Concentrate, coarse, green and by-feed (lees, dregs) should be fed together. Green feed throughout the year can not only save concentrate, but also increase the conception rate and litter size. The pregnancy period is mainly green material and auxiliary feed, and the lactation period is mainly compound feed, which is mainly matched with green material, properly added with auxiliary material, and fed 2 Mel 3 times a day.

? Second, pay attention to the nursing care of newborn piglets

Prepare for delivery according to the expected delivery date (114 days) and the omens of parturition.

1. Disinfect the pigsty, add a pad to clean the hay, and wait for it. Wash and dry sow nipples and vulva before giving birth.

2. Severing the navel. After the piglet landed, wipe the mouth and nose mucus with a dry towel, and then dry the whole body. 10 minutes after delivery, the umbilical cord stopped fluctuating, the umbilical cord could be cut off, and the section was cut off from the three transverse fingers of the piglet's abdomen, and the cross section was disinfected with 5% iodine.

3. Fix the nipple. The first three pairs of nipples have the highest milk production. In order to make a litter of piglets grow evenly, the way to help fix the nipples is to force the big and strong piglets to fix the nipples behind, and let the small and weak ones fix the first three pairs of nipples. It won't change in three days.

4. Pressure prevention: piglets are most likely to be crushed to death within three days after delivery, which can not be ignored. Anti-pressure measures:

(1) there are protective tiles on the side wall of the sow bed.

(2) when sows eat and defecate and return to the pig bed to lie down, piglets are prone to be crushed to death. So there should be someone waiting within three days.

(3) the bedding grass should be short and not too thick. if it is too long and too thick, it is easy to cover piglets, trap piglets and sows lie down without seeing piglets or piglets can not run away and die.

(4) prevent sows from being frightened and trample to death.

5. Heat preservation: in the piglet incubator or supplementary feeding room, install 150Me 200W infrared light or use seasonal birth to avoid giving birth in winter (mainly to carry out planned breeding).

6. Prevent sows from biting piglets. The way to prevent it is to provide adequate drinking water before and after giving birth, and resolutely do not let sows eat placenta and dirty water. Sows who have eaten piglets once are hard to change their bad habits and are resolutely eliminated.

7. Prevent anemia and white dysentery. The piglets were injected with iron-copper mixture 3 days after birth, or fed with iron-copper mixture once on the 3rd, 5th, 7th, 9th and 11th day respectively.

Iron-copper mixture preparation method: ferrous sulfate 2.5g, copper sulfate 1g, cold boiled water 1000 ml. Each head is fed with 1ml / 2ml.

? Third, pay attention to the early feeding of piglets.

Early feeding and feeding is the central link of piglet breeding. According to the habits of piglets such as arched ground and strong imitation, a variety of food inducement methods can be adopted.

The age of inducing food was 7 ~ 8 days after birth.

Temptation food: soybeans, peas, cereal, wheat and other stir-fried, crushed, add sugar or use suckling pig formula feed to add some sugar.

Food inducement method: the premise of food attraction is the sanitary circle. Mix the above food with water, sprinkle it on the ground, let the sows arch the food, and the piglets will imitate. Do it many times a day. If the milk of the sow is too good for the piglet to teach, you can put the sweetened food into a paste and force it into your mouth with your fingers. after a few times, the piglet will arch its own food, no longer than 15 days to learn to eat on its own.

? Fourth, pay attention to the supplementary feeding of piglets

1. Feed: piglet supplementary feed can buy suckling pig feed, and farmers who have the conditions can also prepare it themselves. Reference formula: Baogu 48%, broad bean (fried yellow) 12%, soybean (fried) 8%, wheat bran 16%, rapeseed cake 4%, silkworm pupa (or fish meal) 10%, bone meal 1.5%, salt 0.3%, additive 0.3%, pig multivitamin 0.01%.

Daily feed per head: 0.1 kg at the beginning, gradually increased, up to 0.5 kg at the age of 50 days.

2. Supplementary feeding method: formula feed can be fed with dry powder and mixed tide, but not thinly fed. The green material should be tender, chopped and fed, or it can be put separately. Supplement feeding for 4 times per day for 5 times.

3. The mother and offspring should eat separately. A supplementary feeding room is set up in the sanitary circle, which is reserved for piglets to enter and leave holes for piglets to enter and eat freely, but not for sows. If there is no supplementary feeding room, it can also be replenished, but most of the nutritious suckling pig feed is eaten by sows, which is not economical; if piglets eat sow feed, the weight gain will be slower.

In addition, make sure there is clean drinking water in the sink for piglets at all times. If possible, hydrochloric acid (1000 ml of water, 8 ml of hydrochloric acid) can be added to the drinking water of 3-20-day-old piglets to replenish stomach acid and improve digestion and disease resistance.

? Fifth, do a good job of castration, vaccination, weaning and deworming of piglets.

1. Castration: 35ml 40 days old.

2. Vaccination: paratyphoid vaccine: 45 days old, classical swine fever vaccine: weaning.

3. Weaning: 50ml 60 days old, which can be decided according to the breeding situation of piglets. When weaning, it is best for piglets not to leave the pen, and the sows can be kept in another enclosure. the advantage is that they lose weight without environmental impact.

4. Deworming: 50ml, 90 days old. Deworming essence can be used to wipe ears, 10 kg body weight with 1 ml; albendazole 10 kg body weight 50 Mel 100 mg mixed feed. Zhu Jianyun
