How do you minimize stress by weaning piglets? Recently, the whole country has cooled down and the weather has suddenly cooled. Many farmers have asked about this stress problem about pigs. Today, Huinong.com has come together to discuss with you.
First, do a good pig transfer plan in advance
Before the pig is transferred, the delivery room staff must inform the nursery staff in advance of the time, number of heads, weight and health of the weaned pig. In order for the nursery staff to prepare the bar in advance, preheat the pig house, prepare a special care bar for the weak piglets, and prepare enough feed to provide a clean, dry and warm barn environment for the weaned piglets.
Second, reduce the stress when switching groups
1, the right pig
For pigs with smaller weights, the correct method of catching pigs is to grab the waist of the piglets with one hand and lift them up, and immediately hold the piglets' chest with the other hand; the piglets with larger weights should follow the pigs. The abdomen grabs the pig's thigh and holds the chest with the other hand; the larger piglets can grasp the skin folds in the pig's groin, which can better exert force and avoid the pig's struggle. It is strictly forbidden to directly catch the pig's ears or fore legs to increase the pain and joint damage of the piglets.
2, use the pig board
In order to avoid damaging the pigs when driving the pigs into the nursery, you must use the pig plate to drive away to prevent the piglets from turning around or running around.
3. Control the number of heads transferred
In order to avoid pigs fighting after the nursery, it is best to put the same litter together, one or two litter each time, and distinguish them on the back of the pig with different colored marks. If it is a large group transfer, do not exceed 100 heads per transfer, which is convenient for grouping in the nursery.
4, carefully drive and load
When you turn pigs, you must carefully drive the piglets to avoid stress or damage. When using a pig car to transfer pigs, avoid wearing too many heads at a time, so that each piglet has enough space to stand.
5, to avoid piglets falling
Piglets can weigh up to 7kg when weaned. When transferring pigs, avoid the piglets' heads falling into the columns or aisles. Otherwise, they will be seriously injured. They should be placed slowly on the pig car or on the ground.
Third, reasonable grouping
Weaned piglets should be reasonably grouped according to gender, size and age after arriving at the nursery. Usually weaned pigs will have 15% of individuals, 35% of individuals, 35% of individuals and 15% of individuals, so we should consider the differences in individual size of piglets. In grouping, it is important to take care of the weak and early weaned piglets, which need special care to recover as soon as possible. These weak piglets should be marked before weaning and transferred to the nursery and placed directly in the special care column. Sick or injured piglets should also be found in the care section of the sick pig in time.
1. Preparation of piglets before arrival
Before the piglet arrives at the nursery, the staff of the delivery room must communicate with the nursery staff in advance to determine the time of the pig, the size of the pig, and the age of the pig. The nursery staff must prepare the nursery in advance and prepare for the pig. The specific contents include:
Check that all equipment in the nursery is properly and safely used;
The bar insulation equipment is opened in advance, and the temperature of the bar is preheated in advance (the suitable temperature for weaned piglets is 28 °C);
Set up a special care bar, open the heat lamp and insulation pad;
Set up the pig channel according to the unloading program and set up the pig unloading area (only for the off-site nursery).
2, transfer piglets
After the piglets arrive at the nursery, they can arrange the bar according to the way of one or two litters of piglets to reduce the stress of the group. They can also get all the piglets out of the car and then transfer to the nursery. Piglets that have not been weighed in the delivery room may also be weighed before the piglets are transferred to the nursery.
3. Reasonable grouping
After the weaned piglets are rushed to the empty section, they are reasonably grouped according to the size, sex and age of the piglets. At the same time, the weak piglets and the early weaned pigs are classified into the special care column, and the sick, injured or poorly growing piglets are marked and placed in the sick pig pen.
4, health check
After all weaned piglets were grouped into the nursery, the pigs were thoroughly examined for health, and the sick, injured or poorly growing piglets that were not previously found were marked and placed in the care column. According to the actual situation, treatment is carried out.
5, count the pigs
At the same time as the health check, the number of pigs was counted, and the breeds of the pigs, weak pigs, and sick pigs were counted separately.
6, detailed records
Record information on the transfer of the piglets, including the number of columns, date, weight, total number of piglets and number of weak piglets, and place nursery records, immune tracking cards, temperature monitoring tables and water consumption records in the nursery.
Regarding the question of how to minimize the stress of transferring weaned piglets into the nursery school, we will talk about this for the time being. Later, Hui Nongwang Xiaobian will update more details about how the pigs are properly grouped. Welcome everyone. Continue to pay attention.
