Unlocking Performance in Sow Nutrition

Phytogenics: Potent performance enhancers in sows

Biomin® P.E.P. functions in three ways, i.e. through (1) modifications of the gut microflora, along with (2) a stimulation of digestive secretions and, particularly in sows, (3) a positive impact on feed intake, all in all resulting in improved digestion. An increasing number of trials conducted under experimental and field conditions have shown that inclusion of well-selected phytogenic compounds in diets for sows increases the voluntary feed consumption in the lactation period. Moreover, there is growing evidence that phytogenics have a stabilizing effect on digestion, resulting in improved feed conversion (Kroismayr et al., 2005). Thus, on one hand more feed is ingested; and on the other nutrients and energy are better converted into performance. Consequently, the overall efficiency of production is increased, which is the major aim in view with rising prices for commodities.

Data presented in Figures 1 and 2 were obtained from trials in South and North America. In both trials, sows were fed basal feed either with or without supplemental Biomin® P.E.P. Although there was a dramatic increase in feed intake in both groups during the early lactation period, sows fed phytogenics consistently ingested more feed as compared to the control sows.

Positive effects of phytogenics in sow nutrition are usually reflected in increased litter performance. Results from different trial locations are summarized in Figure 3. In these trials, supplementation of diets for sows with Biomin® P.E.P. increased average weaning weight of the piglets by 3 to 9%.

The latest results from another field trial in Chile (Table 1) confirmed the positive observations that were made in the above mentioned studies.

Several investigations have additionally shown substantial reduction in the incidence of diarrhea in piglets. Data from studies carried out in different locations in Vietnam indicate that the mortality of piglets can be dramatically reduced through supplementation of sow diets with Biomin® P.E.P. (Figure 4), even under challenging tropical and humid conditions.

The impressive observations regarding the efficacy of Biomin® P.E.P. in all the trials are further enhanced by a substantial economic advantage. As an example, Table 2 shows the production results from two sow operations located in a high-density swine production area in Hohenlohe, Germany.

The general recommendation for application of Biomin®P.E.P. is shown in Figure 5. Inclusion of Biomin® P.E.P. 1000 (2 kg/t) from approximately 10 days prior to farrowing until 10 days after farrowing is regarded as optimal period of supplementation under aspects of performance and profitability. Depending on individual farm conditions, dietary supplementation with phytogenics can be carried on with a reduced inclusion rate ( 1 kg/t) until weaning.

A critical review of published literature reveals that a lot of research is needed to further explain the benefits and mode of action of different phytogenic agents. It seems clear that the effects of phytogenics are dose-dependant. Overdosing will most likely constrict feed palatability and result in low feed intakes and depressed growth performance, while insufficient levels of phytogenic agents will remain ineffective. Furthermore, it should be kept in mind that the group of phytogenics is highly inhomogeneous with regard to biological activities and flavoring properties of single active ingredients. Thus, certain mixtures of phytogenic compounds may be more efficient than single compounds. Biomin^® P.E.P. has proven highly efficient in sow nutrition, with main benefits regarding feed intake and piglet performance.

Conclusion

As shown in the presented studies with sows, well-selected phytogenic compounds (Biomin® P.E.P.) represent a Natural Growth Promoter (NGPTM) for pigs. Supplementation of diets for sows results in increased body weight of piglets at birth and weaning and improves profitability in sow production operations. A beneficial influence on body condition and fertility is another argument for including Biomin® P.E.P. in rations for sows.
