FreshFoss – best in test: Improves the aerobic stability of the feed Heat spoilage in TMR is a common problem. Heat observed in the TMR should be considered an important feeding problem, and it is strongly recommended to regularly check leftovers for heating. The Danish Agricultural Advisory Service (SEGES) has examined different additive solutions for stabilising aerobic stability of TMR. According to the test results, the Vilofoss product FreshFoss TMR was found to be significantly superior in terms of improving the aerobic stability of TMR, compared to propionic acid, sodium benzoate and Salvana TMR. Three tests were done on three different days to demonstrate the difference between control (potassium sorbat) and FreshFoss. Results shown in figure demonstrate an average of 6 percent higher efficiency to prevent heat spoilage in a total mixed ration. Another way to represent aerobic stability is to measure the time to a given temperature rise in the complete feed, e.g. 5 degrees Celsius. The higher the number of hours - the more efficient the product. This is summarized in the table. TREATMENT DAY Potassium sorbate, 0.4 kg/t FreshFoss 0.4 kg/t TEST 1 100 113 TEST 2 100 98 TEST 3 AVERAGE 100 100 110 106 Table 1. The aerobic stability of potassium sorbate and FreshFoss compared at the same supplementation rate. Potassium sorbate is 100% and the effectiveness of FreshFoss is relative to this. On average, the aerobic stability of FreshFoss was 6% better than potassium sorbate. 115 110 CONCLUSION 105 The difference in the efficiency of the products 100 in relation to the reduction of heat generation in complete feed can be demonstrated by a simp- 95 le comparison of temperature development measured with temperature logs. The compari- 90 son showed that FreshFoss is more effective at reducing heat generation in complete feed than pure potassium sorbate.
