Technonews:Use of pronutrients with an immunostimulant activity in aviculture

2017-04-20

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

Day	Vaccine	Administration route	Doses	Comments
1	IBD	Injection	1 dose	Hatchery
1	ND+IB	Aerosol	1 dose	Hatchery
1	ND+H9	Injection	0.15 mL	Hatchery
9	ND+IB	Eye dropping	1 dose
20	ND	Drinking water	2 doses

RESULTS

PRODUCTIVE PARAMETERS

Batches	Final weight (kg)	FCR	Survival rate	Efficiency index
Batch 1	2.95	1.57	97.5%	446.8
Batch 2	2.86	1.59	96.3%	422.5
Difference	+0.09	-0.02	+1.2%	+16.3

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

ANTIBODY TITERS

Disease	Days	Batch	Mean
H9	25	Pronutrients	2.2
	25	Control	2.0
	33	Pronutrients	2.9
	33	Control	2.4
ND	25	Pronutrients	2.8
	25	Control	2.6
	33	Pronutrients	4.6
	33	Control	3.8

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.

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