Danisco releases new phytase to benefit pig industry

 

 

Danisco announced the release of new generation E. doli phytase that represents an exciting step forward for the pig feed industry.

 

Anne-Marie Debicki-Garnier, Senior Technical Manager for Danisco Animal Nutrition,

in her presentation "Efficacy of a new phytase in swine nutrition", outlined the results of two trials conducted by ADAS, UK.

 

The first trial was set up to determine the efficacy of a new generation E. coli phytase (Phyzyme XP, Danisco) in improving phosphorus and calcium digestibility in young pigs.

 

The second trial was designed to assess the ability of the new generation phytase to improve liveweight gain and feed efficiency of young pigs fed diets reduced in calcium and phosphorus.

 

For the first trial, 24 male pigs, with start weight of 7 kilogrammes, were split into 4 dietary groups - positive control, negative control (digestible phosphorus reduced by 0.14 percent and calcium reduced by 0.12 percent), negative control supplemented with either 500 or 1000 FTU/kg new generation phytase.

 

Phytase addition significantly improved the coefficients of digestibility of calcium and phosphorus compared to both the positive and negative control.

 

In the second trial (35 days duration), 288 male piglets (with a start weight of 7.7 kg), were allocated to 6 treatments. The treatments included a positive control and a negative control, with phosphorus and calcium reductions similar to those used in the first trial. The negative control was also supplemented with the new generation phytase at 250, 500, 1000 or 2000 FTU/kg feed.

 

Pigs fed the negative control diet showed significantly lower liveweight gain and poorer feed efficiency versus the positive control. Liveweight gain and feed efficiency improved as the level of phytase added to the feed increased, with 500

 

FTU phytase/kg feed restoring performance to the same level as pigs fed the positive control diet.
