Absztrakt (kivonat)
The aim of the study was to determine the nutrient content, fermentation quality and microbial status of wet tomato pulp silage after applying different treatments in two consecutive years. In the first year, dried whole seed wheat (20% based FM) was applied in order to reduce the hazard of effluent production and undesirable fermentation processes and to increase energy content of tomato pulp. Ensiling was carried out in metal barrels/treatment with a capacity of 150-180 kg/barrel. In the second year, dried ground corn (20%) was applied for the same reasons as before and to increase nutritive value of the by-product. In the first year, the applied dried whole seed wheat (used at 20%) increased the net energy content for maintenance of tomato pulp, which has an important role in game feeding during the winter (roe deer and red deer, wild boar). The calculated lactation net energy content was similar to a maize silage harvested with approx. 25-30% starch content. Mixing of 20% dried whole seed wheat reduced significantly the acetic acid (P≤0.05), the volatile fatty acid (P≤0.05) concentration, while increased the lactic: acetic acid ratio in the core of the silages as compared to T2 (T2: 1.72±0.07 vs T3: 3.25±0.09). A lower fermentation intensity was found in combination with a better organic acid profile, presumably due to a higher DM content in 20% wheat treatment as compared to tomato pulp. However, it is not recommended to add whole seed to the wet by-product due to the negative effect on the top 1-20 cm layer. In the second year, low fermentation intensity was found in the control tomato pulp (20% corn) baled silage, as well as an undesirable fermentation process was found in the case of 0,5% salt treatment in the mixed tomato pulp baled silage. Therefore, application of salt is not recommended. Inoculation effectively inhibited the production of butyric acid and reduced the protein loss by 6 % as compared to the control, therefore it is highly recommended to apply as silage inoculant during the ensilage of the wet by-product. In summary, it was confirmed that the new baling system was able to form well-shaped and stable bales. High density, quick wrapping (within 120 sec after bale-forming), had a beneficial effect on fermentation quality. The study showed that wet tomato pulp had a limited fermentation capacity, but under anaerobic conditions it was possible to store for long term (100 days) with a good microbial status. It is recommended to use dried ground cereal as an additive (20%) to increase dry matter and energy content, moreover to improve volatile fatty acid composition of the wet tomato pulp silage.
