Harvested crops

BASF offers solutions for optimizing nutrient value and quality of harvested feed as well as improving hygiene of byproducts and farm-based mixed feeds. Those are propionic acid Luprosil®, formic acid containing Amasil® NA and Lupro-Grain®, Luprosil® NC, Lupro-Cid® NA and Lupro-Mix® NA.

Sample calculation
1. The measurement of the grain moisture content shows 18%. The desired storage period is 12 months. In the dosing table for Luprosil® the value of 0.65% is read off for 18% moisture content and 12 months storage duration. This corresponds to 6.5 litre per tonne grain.
2. The screw conveyor conveys 1,500 kg barley in 5 minutes. This results in a conveyor rate of 18 tonnes per hour.
3. The dosing unit now has to convey 6.5 litres of Luprosil® x 18 tonne grain = 117 litres in one hour. A conveyor rate of 120 litres/hour (117 litres rounded up) is set at the dosing unit. In order to make sure that no untreated grain reaches the store, it is important to switch on the dosing pump first, and then the screw conveyor.
Dosing allowances and further tips for grain preservation
Conveying preserved grain by blower: If grain preserved with acid is to be conveyed further by a grain blower directly after acid treatment, intermediate storage of one hour is necessary. If direct connection of the blower after the dosing equipment cannot be avoided, the product application rate recommended in the table must be increased by at least 10%.
Brewer’s grains
Especially during the summer months brewer’s grains spoil within a few days because they offer ideal conditions for yeasts and fungi. With Luprosil® brewer’s grains can be protected against spoiling. For surface treatment (approx. 30 cm layer thickness) 1 litre Luprosil® and 4 litre water per square metre must be mixed and then poured onto the surface. Then seal off the brewer’s grains (air-tight) with plastic sheeting at once. Additional mechanical working in is advisable. Do not store for more than three weeks after commencement of unloading. The same effect can also be achieved with 1 litre of Lupro-Mix® NA mixed with 4 litres of water. Application is the same as for Luprosil®.
Recommended dose of Lupro-Mix® NA (or Luprosil®) for surface treatment
The mixing ratio for pour-on solutions is 1: 4 (1 litre Lupro-Mix® NA or Luprosil® is mixed with 4 litres water). The following quantities of this pour-on solution are used to treat a 50 cm thick layer of silage depending on the dry matter content.
Treatment in the case of post-warming
Subsequent post-fermentation and post-heating of the silage leads to nutrient losses and reduces feed intake. This phenomenon occurs frequently in the Total-Mix-Ration (TMR). Please note the special dosing tips in chapter 6.5 for this. To combat post-heating of silage which has already heated up during or after being unloaded from the feed stock, we recommend Luprosil®. Heated grain must be unloaded from the silo and spread out approx. 20 cm high. 0.5 litre Luprosil®, diluted with 2 litres water, is then poured over each square metre feed and mixed well. The silage cools down quickly and can be fed immediately after cooling without any waiting period.

The cut faces in the silo stock can also be treated with Luprosil®. 0.5 litre Luprosil®, diluted with 2 litres water, is then poured over each square metre of the cut face. After this the feed stock must be covered carefully again. During pauses in silage making Luprosil® treatment with the same application rate can be carried out to prevent heating and mold formation in the top layer of green material.
