The choice of nursery pig feeder

The material cost accounts for more than 70% of the cost of raising pigs in the nursery and fattening stages, so the choice of feeders is very important. How to get the required feed for each pig, and to minimize waste, is a matter to consider when designing and selecting feeders.

The first question for a pig producer or farmer to consider is what type of feeder I want. How many pigs can this feeder use?

Here I would like to introduce the concept of an eating position where a feed bit is the space occupied by a pig's feed.

The question then becomes how to assess the quality of the feeding position, and each feeding position can be used by several pigs.


Feed position quality

 1. Feeding width Width of pig shoulder width +10%, recommended width = 6.7 (cm) * weight (kg) ^ 0.333

 30kg corresponds to 20.8cm, 60kg corresponds to 26.2cm, and 120kg corresponds to 33cm

 2, feeding depth

 Nursery Pig 10-20cm Finishing Pigs 25-30cm Conservation Fattening One 25-30cm

 3, edge height

 Nursery Pig 5-10cm Finishing Pig 10-15cm Conservation Fattening One 10-12cm

 4, there is no block between the feeding position


If 1.1 times the shoulder width can be achieved, there will be almost no fighting situation in the block to the pig's shoulder, blocking to the head about 7% of the fighting rate, and if there is no blocking, there will be an average of about 19% fighting rate. . The experimental data also showed that the feed to the pig's head or shoulder was the least wasted. This is why some experts do not recommend the use of tube feeders.

In addition, many experiments of wet and dry feeders have shown that they are beneficial to the production performance. One thing to note when using dry and wet feeders is that the water pressure of the wet and dry feeders is lower than that of the drinking fountains. The general 70 Kpa waterer is 140 Kpa.


Each feed position can feed several pigs

 Traditionally, it is recommended to supply 5 pigs per feed location, and there is also a single monomer feeder that can manage 40 pigs.

The maximum number of pigs that can be fed is actually 24 hours a day. This will affect the pig’s daily gain and feed ratio. Experiments have also shown that the dry and wet feeder feeds 10 pigs per feed position. The pig's feed ratio is lower.

There is also a phenomenon that needs our attention. Actually, the pig's intake time decreases with age and weight. The data we obtained from the equipment used in the Austrian feed assay also reflected this trend.


This brings two issues to consider:

 Feed wastage rates may be higher in pigs, and is the feeder setting more of a factor of piglet consideration?

 Pigs take longer to eat, and sometimes there is insufficient food intake when they are younger.


In general, the following recommendations are made for several pigs per feed location:

 1, dry feeder can feed 8-10 pigs per level;

 2, dry and wet feeders can feed 12 pigs each;

 3, tube feeder (more commonly used in the country) PIC manual gives advice is 11 pigs per side, according to the length of the trough is every 51mm per pig, which is actually more than we now each trough 30 - The standard for 35 pigs is much lower.


I asked Dr. Harold Gonyou about trough selection. His opinions are mainly for your reference.

 1, the best use of dry and wet powder feeder to increase feed intake, if the particles do not have much impact

 2. The tube feeder will increase the fight, but his experimental results seem to be good

 3, the material size should pay attention to, to meet the needs of the pig's largest situation (specific indicators see above)

 4. How many pigs per feed place should be considered according to the pig's feed intake


Personal advice follow-up is best to use stainless steel trough, there is an effective block to the head between each level, each level for several pigs index can be slightly lower, for daily gain and feed ratio Help, after all, is that the one-time cost of the feeder compared to the long-term feed costs is very limited.
