There are currently sows that farrow many more piglets. Figure 1. Today, there are sows that farrow many more piglets and more viable than before. The need for milk is so great that different systems are being developed to provide artificial milk to piglets as an alternative. Are these systems necessary? Are modern sows really capable to produce all the milk their piglets need?
Soaring prolificacies and increasingly better management have shown —in a practical way— that a sow with 14 teats can feed 16 piglets without problems. What does "without problems" mean? Without the piglets becoming uneven, with good weaning weight, without differences with other piglets who have had "their" own teat for the duration of the lactation period. We had always known that each piglet has its own teat, the first days of life a hierarchy being established between siblings that ends up with the allocation of the best teat for each piglet based on their capabilities.
We now know that this is only half true. This is true when there are more teats than piglets. But, if there are more piglets than teats, and they are all strong and viable, teats are shared. This allows for the full use of the available milk. Teats are completely drained of milk, and this stimulates greater milk production. Once we make sure teats are shared, the next step is to consider lifting partitions in the farrowing unit , thus allowing piglets of different litters to mix and socialize.
Farrowing room with partitions removed. This is where the DCAB value and its differentiation between gestation and lactation feed comes into play. That promotes the early release of calcium in particular from the bone depots with the onset of colostrum formation and thus compensates for the supply gap due to absorption from the intestine. That ensures that the metabolism is supplied with minerals throughout the entire lactation period, which is also necessary for high daily milk production.
The box demonstrates how the DCAB can be calculated. Insoluble structural carbohydrates are used fermentatively in the large intestine of the breeding sow by the microbial population. The resulting short-chain fatty acids have a direct or indirect positive influence on the stability of the microbial population in the intestine.
In particular gram-positive bacteria such as Clostridia types are limited in their development. The physical and chemical properties of the structural carbohydrates are important for a healthy bowel function — i. In addition to their fermentability, they bind water in the intestinal lumen and thus facilitate faecal excretion. A minimum content of ADF that is less fermentable also plays a role here. Any avoidance of constipation is also important for the health of breeding sows.
That is because blockages significantly increase the risk of endotoxin flooding lipopolysaccharides — cell wall components of gram-negative bacteria. These can lead to inflammatory processes in the metabolism and are often jointly responsible for milk deficiency symptoms as part of the MMA complex.
