Commercial products for finishers: Luprocid and Natuphos

Abstract
Two products for finishers in the weight interval 28-102 kg have been tested in one herd, and the products were compared to a control mix.

The test was carried out in cooperation with BASF who delivered the products. There were 24 blocks (replicates) of 3 pigs per pen, totalling 72 pigs per group in the test. The test comprised the following treatments:

The analyses of the feed conformed well with the calculated and analysed content of nutrients with the exception of Ca and P. The analysed content of both Ca and P was in all groups above the calculated levels (Ca: 1.0-1.3 kg above, P: 0.4 kg above), which means that the pigs in groups 3 and 4 were not – as planned – under-supplied with Ca and only to a minor extent under-supplied with P.

The analysis of phytase activity (Natuphos) showed a high natural content of phytase in groups 1, 2 and 4 compared to results from previous tests. In group 3 (with phytase added) the content was as expected the highest, but the difference in phytase activity between groups 1 and 3 was smaller than expected. The analyses were carried out by BASF.

The content of organic acids conformed fairly well with the calculated content of the added product (Luprocid).

There was no difference between the groups in treatments for diseases.

The production value of the individual feed mixes was calculated on the basis of the production results, and is stated as gross margin per pen place per year using the same price per FUp for the feed mixes. Overall, the test showed no difference between the control group and the products tested from BASF. An addition of Luprocid to finishers thus had no effect on the production results. It is not possible to unambiguously establish the effect of adding phytase to finisher feed in this test as the content of calcium and phosphorous in all the mixes was higher than planned.
