Raise pigs for several months.

For example, the weight of binary pig reaches 70 kg, the inner ternary is 80 ~ 85 kg, the outer ternary is 95 kg, and the British PIC pig 105 kg is the timely weight for slaughter. In addition, when the pig market price is high, the heavier the weight, the better; When the price is low, it's best to be light, so as to reduce feed consumption and cost.

Current management

1, suckling piglets?

(1) Thermal insulation and pressure protection. Suitable temperature for suckling piglets: 65438+32℃ ~ 28℃ for 0 ~ 7 days and 28℃ ~ 24℃ for 8 ~ 35 days. The temperature in the shed should be controlled at 18℃ ~ 22℃ and the relative humidity should be 50% ~ 70% to keep the air fresh. Piglets should be equipped with an incubator or incubator, and a 250-watt infrared light bulb should be hung at the bottom of the incubator or 30 ~ 40 cm away from the bottom of the incubator. At the same time, do a good job in piglet care and install a baby protection fence in the delivery fence.

② Eat bovine colostrum and fix nipples. Piglets should be artificially ingested with enough colostrum 1 hour after birth. Nipples should be fixed within 2 ~ 3 days after birth. Fixed nipple is mainly optional, supplemented by individual adjustment. Piglets with small birth weight are fixed on the front nipple, and piglets with large birth weight are fixed on the back nipple.

(3) Iron supplementation and litter. Within 2 ~ 3 days after birth, piglets were injected with iron preparation intramuscularly, and the dose of iron per pig was 100 ~ 150 mg. Lactating sows are fed 10 ~ 12 piglets each. For piglets with litter size greater than 12 or less than 7, overfeeded piglets are fed to sows with smaller litter size and the difference is not more than 3 days. Piglets must eat enough colostrum before overfeeding.

For sows with too few farrowing, according to the farrowing principle, two litters of piglets can be merged into 1 litter, and one litter will be very healthy. Sows with sufficient milk are fed. Piglets must eat enough colostrum before nesting.

(4) Open food and feed. Piglets should be trained to drink water at the age of 5 days, eat at the age of 7 days and eat at the age of 20 days. After a piglet begins to eat, it is supplemented with complete ingredients and fed with wet feed (feed-water ratio 1: 0.5) 5-6 times a day.

⑤ Castration and weaning. Piglets are castrated at 25 days old and weaned at 35 days old.

⑥ Hygienic disinfection. Clean the shed twice a day to remove feces, and disinfect the passages in the shed with 2% caustic soda water solution or other disinfectants 1 time every week.

⑦ Prevention and control of epidemic diseases. Piglets are vaccinated with swine fever vaccine at the age of 20 days after birth.

2. Weaned piglets

① Prepare before entering the pig. Before the piglet breeding house is transferred to piglet 1 week, it is necessary to inspect and maintain the equipment in the shed, clean the shed, and then disinfect it with 2% caustic soda water solution or other disinfectants.

② Feeding. After the piglets enter the house, they are still fed with the original feed within 2 weeks, and the intake is controlled within 1 week, and they are heated 5 ~ 6 times a day to drink freely. After 2 weeks, it gradually transited to the stage of pre-fertilization, adopting wet feed type (feed-water ratio 1:0.5), feeding 4-5 times a day, and drinking freely.

③ management. After weaning, transfer the original nest to the piglet breeding house. The indoor temperature is controlled at 25℃ ~ 20℃ and the relative humidity is 50% ~ 70% to keep the air fresh. Clean the fence twice a day, and disinfect the passage with 2% caustic soda water solution or other disinfectants every week 1 time.

Piglets were inoculated with swine fever, erysipelas, pneumonia and piglet paratyphoid vaccine at the age of 55-60 days after birth. Piglets will be repelled by parasites inside and outside the body before being transferred to another group. Piglets were raised in the piglet house for 5 weeks and then transferred to the growing and finishing pig house.

3. grow and fatten pigs?

① Prepare before entering the pig. During the first 1 week of transfer to weaned piglets, the barn should be inspected and maintained, cleaned, and then disinfected with 2% caustic soda water solution or other disinfectants.

② Feeding. After the weaned piglets enter the house, they are fed with dry powder or wet feed (feed-water ratio 1: 0.5). At the beginning of fertilization, feed it 3 ~ 4 times a day, unlimited times, and drink freely. In the later stage of fattening, feed 2 ~ 3 times a day, feed infinitely and drink freely.

③ management. The weaned piglets were transferred to the growing pig fattening house and divided into groups according to the principle of similar pig breeds, weight and physical strength, with each group 10 ~ 20 pigs. After weaned piglets are transferred to growing pigs, they should be trained in time and gradually develop the habit of defecating, sleeping, eating and drinking in a fixed position. The indoor temperature is controlled at 2 1℃ ~ 16℃ and the relative humidity is 50% ~ 70% to keep the air fresh.

Clean the shed and remove feces twice a day, and disinfect the passages in the shed with 2% caustic soda solution or other disinfectants 1 time every week. Usually observe the situation of feeding pigs. Excrement and mental state, isolation and treatment in time when diseases are found. When the pig's weight reaches 90 ~ 100 kg, it will be slaughtered.
