Pigs have been kept as livestock for more than 10.000 years whereby the husbandry has intensified greatly over the past few decades. Around 1/3 of global meat production today originates from swine. Despite large regional differences, the combination of breeding, improved husbandry methods and need-based nutrition has made high performance in fattening and piglet production possible. This in turn places ever increasing demands on feeding and the quality of feedstuffs. 

Ideal protein instead of crude protein

In swine husbandry in particular the topic of nitrogen balance and groundwater nitrate contamination is a major issue. Modern swine husbandry must make a contribution to increased sustainability. When running a feeding strategy with reduced crude protein (XP) it is particularly important to pay attention to an adequate supply of essential amino acids and the correct ratio between them. In addition to DL-methionine Kaesler as Partner of Ajinomoto Eurolysine S.A.S offers the amino acids L-lysine, L-threonine, L-tryptophan and L-valine. Supplementation with L-valine enhances the possibilities for feed optimization as the more the crude protein content is reduced, the higher the corresponding amount of supplemented highly digestible amino acids must be. Not only the quantity must be higher, but also the spectrum. Contact our experts if you would like to find out more about suitable compositions to meet your specific needs.


The key to successful rearing is achieving high feed intake directly after separating the piglet from the sow. The aim is to prevent any shortages in energy, protein or vitamin supply which may pose a risk to health or limit performance. This challenge can be counteracted by increasing the attractivity of the feed. Kaesler has decade of experience in composing the right flavors for this purpose. 

A further significant approach is the optimized convertibility of the feed. Particularly the insoluble and soluble non-starch-polysaccharides (NSP) in cereals can have a negative impact on nutrient resorption and conversion through the so-called “cage effect” and increased digesta viscosity. A modified Chymus Passage, morphological and histological changes as well as effects on the microbial communities in the various sections of the intestine are involved in this process. Using suitable NSP-degrading enzymes provides effective help here. An adequate supply with vitamins is also essential during this phase.

Lactation period

32 and more weaned piglets per sow and annum are not uncommon nowadays. The number alone however, is no cause for celebration if the sow suffers as a result. It has to mobilize all its reserves to supply the litter adequately. In the worst case this can lead to a dangerous emaciation as a result of protein / muscle mass degradation. During lactation it is therefore important to make it possible for the animal to burn own fat reserves as effectively as possible. Energy generation can be optimized through supplementation with L-carnitine which is absolutely necessary for cellular metabolism in order to transport the long-chained fatty acids through the membrane of the mitochondria.
