How many days has the pig been born? When can I get some opening material?

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. Piglets are castrated at 25 days old and weaned at 35 days old.

Piglets grow and fatten:

1, preparation before entering the pig:

Before transferring to weaned piglets 1 week, the fattening house for growing pigs should be inspected, maintained and cleaned, and then disinfected with 2% caustic soda water solution or other disinfectants.

Step 2 feed:

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

3. Management:

Transfer (1) weaned piglets to growing pig fattening house, and group them according to the principle of similar pig breed, weight and physical strength, with 10 ~ 20 piglets in each group. After the weaned piglets are transferred to the growing pig fattening house, the temperature in the house is controlled at 265,438+0 ~ 65,438+06℃, and the relative humidity is 50% ~ 70% to keep the air fresh.

(2) 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. ? [2]

Extended data:

Arch soil characteristics:

1, pigs have the genetic characteristics of arching soil, and arching soil for food is a significant feature of pig feeding behavior.

2. The pig's nose is a highly developed organ, and the sense of smell plays a decisive role in digging the soil to find food. Although in modern pigsty, pigs still show the characteristics of arch foraging. Every time they feed, they try to occupy a favorable position in the trough, and sometimes they trample on their forelimbs to feed.

3. If the trough is easy to access, some pigs even get into the trough and stand in a corner of the trough, just like a wild boar arching for food, arching along the trough with a kiss and stirring the food all over the floor.
