What kind of pigs are suitable for keeping together? How to group pigs scientifically?
For pig farms, one of the unavoidable tasks in adjusting the relationship between pigs is grouping. Reasonable grouping can make the relationship between pigs more harmonious, thereby minimizing the fighting between pigs and ensuring their own growth and development speed.
Unreasonable grouping will intensify the struggle among pigs, making the strong stronger and the weak weaker. At the same time, too much fighting among pigs will inevitably lead to trauma (such as hoof cracking, lameness, etc.), which may even cause casualties in serious cases.
So, how to group pigs scientifically? There are some principles and indicators that must be paid attention to:
1. Breeding density
Reasonable grouping of pigs is also to a certain extent to maximize the use of the breeding facilities of the pig farm, thereby increasing the output value per unit area and increasing the breeding efficiency of the pig farm. But you can't increase the density unprincipled, otherwise it will be counterproductive.
Generally speaking, we recommend that there be about ten fattening pigs in a pig house, and no more than fifteen pigs at most (depending on the area of the pig house), which is conducive to the formation of a joint order among the pigs.
On the premise of limiting the number of single houses, we should also pay attention to the unit area that each pig can occupy. In the piglet stage, a pig house area of at least 0.7 square meters must be ensured, and when it grows to medium pigs or above , a pig house area of no less than 1.2 square meters shall be guaranteed for each pig. Only in this way can a safe distance be kept between pigs and pigs, so as not to make pigs too nervous and aggravate unnecessary fights.
2. Pig weight
In the case of ensuring the living area of the pigs, the next thing to do is to group them. There are also some reasonable data support for the basic principles of grouping.
Take piglets as an example, when grouping pigs, the weight difference between pigs should not exceed six catties (at most ten catties); In the juvenile stage of the pig, if the food intake is large and the weight gain is fast), the weight difference between the pig and the pig is generally more than 10 catties (up to 16 catties). In this way, the big pigs will not bully the small pigs, and it can also ensure the normal feeding of the weak, so that the growth of the pigs can be maintained at the same level.
In addition to this basic grouping principle, other grouping principles that can be referred to include the talent, personality and physical health of different pigs. Although these principles are not as important as body weight indicators, they should be properly considered. For example, some irritable and aggressive pigs would rather be eliminated than let them be the black sheep in the herd.
