Swine grouping and group stress

In the live pig feeding process, it is always a problem that it is difficult for the scale farms to group the group of piglets that have reached the age of one month. In the process of grouping and merging, mutual fighting between pigs often affects the normal growth and development of pigs and their production performance. Severe pigs may cause ear cracks, leg cramps, and even death, causing unnecessary economic losses to farmers. Han Jianguo, who specializes in raising pigs in Baibiao Township, Nan County, Hunan Province, reminded the farmers that the pigs were grouped together and paid attention to each other.

The principle of grouping is to feed pigs with similar sources, body weight, body condition, temperament, and feed intake in pig pens and group them in groups and feed them in separate troughs so as to ensure the normal growth and development of pigs. The weight difference in the same group of pigs should not be too large. Piglets do not exceed 3-5 kg ​​and shelf pigs do not exceed 5-10 kg. After grouping, it should be relatively stable. Generally, it should not be arbitrarily changed.

Suitable density. Generally, each continuous piglet accounted for 0.7 square meters in the fence area, and the finishing pigs each had 1.2 square meters. Each group is suitable for 10-15 heads. In winter, the stocking density can be appropriately increased and the stocking density can be appropriately reduced in summer.

The key to grouping methods together is to avoid biting each other in the early stages of the group. According to the biological characteristics of the pig, the following principles can be mastered, namely, leaving the weak and leaving no strength, leaving the weaker pigs in the original circle, and the stronger pig tune. Out; more demolition does not remove, less pigs stay the original circle does not move, the number of heads into the number of pigs with fewer heads; night and not together, the same group of pigs sprayed with the same drug, Such as sprinkling semen, so that the smell of each other is not easy to distinguish, in the evening gregarious; the new column with the same tune, the two groups of pigs equal heads, strengths and weaknesses, and the group when the same tune to the new pigsty; first cooked and the two groups of pigs with the off In larger stadiums, they are grouped together for 3-7 days; hunger-sweeping and plucking, pigs are split in the hungry, and they are fed immediately after the group so that the pigs can sleep well after they eat and drink, and do not invade each other.
