In a trial carried out in XiangYai, HeBei (China) in broiler chickens, the effects of a product composed of pronutrients with an immunostimulant activity on productive performance and the immune response were evaluated.

BATCHES (12000 broilers/batch)

• BATCH 1 (Pronutrients): Natural immunobooster (pronutrients) through drinking water at 0.25 ml/L. Administration on days 9 – 12 and 20 – 23, for 12 hours
• BATCH 2 (control): standard diet without immunoboosters

VACCINATION PROGRAM

RESULTS

PRODUCTIVE PARAMETERS

Moreover, on day 35^th the control group (batch 2) showed a reduction of feed intake and a mortality increase.

ANTIBODY TITERS

CONCLUSIONS

It has been proved that the administration of pronutrients with an immunobooster activity to broilers improves the following productive parameters:

• Final weight (+4.24%)
• Feed Conversion Rate (-1.25%)
• Efficiency index (+16.3 points)
• Mortality (-1.2%)

In addition, there is a higher immune response against vaccination, which is seen by a greater mean antibody titer.

• H9 titers: +10% (day 25); +20.8% (day 33)
• ND titers: +7.7% (day 25); +21% (day 33)

Pronutrients with an immunostimulant activity are commercialized under the name Alquernat Immuplus.
