The milk production per hectare is higher with SOBAC forages, thanks to a better soil balance, thus allowing more calves to be fed
Crop/Production
Frédéric and Angélique Rozier, GAEC de la Grange Blanche, in Briennon (Loire), France; 216 hectares including 15 of cereals, 10 of temporary meadows and the rest in natural meadows, 150 Charolais cows and 40 heifers for replacement. Testimony collected in autumn 2016.
Product/Usage
- Bactériosol concentré (since 2014) /
- Bactériolit (since 2014) /
Results
- Improvement of soil structure
- Improvement of grassland flora
- Reduction in chemical inputs
- Better balance of fodders
- More balanced diet
- More sanitary buildings
- Better calf start-up
- Improved carcass weight
- Improved live weight
- higher profitability
1. TECHNICO-ECONOMICAL STUDY :
Following comparative analysis of forages carried out in 2015 on the same parcel of natural meadow, cut in half, with a control (untreated manure + 30 units of nitrogen) and a SOBAC (manure seeded with BACTÉRIOLIT), with an equivalent yield, it was possible to measure the autonomy in milk and meat production. Note: LSU = Livestock Unit ; MFU = Meat Fodder Unit ; DPI = Digestible Protein in Intestine.
2. FEEDING CATTLE IN AUTONOMY :
For a 650 kg cow (450 kg carcass weight), target of 1,2 kg/day, on a fattening period of 150 days. The needs are: 11.2 MFU/day/LSU and 1,120 DPI/day/LSU i.e. 1,680 MFU/LSU and 168,000 DPI/LSU for 150 days of fattening.
3. IMPROVED MARGIN IN MEAT SALES :
