Performance records were collected for the before and after periods.
The following parameters were recorded per batch: weaning weight
at 25-day age, market weight, mortality in both nursery and finishing
pigs, Feed Conversion Ratio (FCR), Average Daily Weight Gain (ADWG)
and drug cost per finisher.

This study was conducted in a commercial farrow-to-finish farm
with a herd size of 1000 sows in Jiangxi province in China. This farm
had been vaccinated with a local PCV2 vaccine (a Cap protein subunit
vaccine based on baculovirus vector; two doses at 14 and 35-days of
age) and an imported Mycoplasma hyopneumoniae vaccine (two doses
at 7 and 21-days of age), with slaughter pigs sold from September
2013 to August 2014. Beginning September 2014 through August
2015, pigs were sold that were vaccinated with the combination of
Ingelvac MycoFLEX® and Ingelvac CircoFLEX®, 1 dose of 2.0 ml (1.0 mL
Ingelvac CircoFLEX® and 1.0 ml of Ingelvac MycoFLEX®, at 14-days of
age) to immprove performance, convenience and compliance.

MATERIALS AND METHODS
ADWG
PCVD (Porcine Circovirus type 2 (PCV2) diseases) and EP (enzootic
pneumonia) are two of the economically important swine diseases
in China. Single or co-infections with these pathogens are associated
with several clinical signs, such as postweaning multisystemic
wasting syndrome (PMWS), stunting, cough, diahrea, dermatitis and
nephropathy. The purpose of this study was to evaluate the efficacy
of the combination of Ingelvac CircoFLEX® and Ingelvac MycoFLEX® in
a farm.

The changes before and after use of the combination in mortality,
FCR and ADWG of different batches are showed as follows (figure 1
and 2). The mortality was reduced from an average of 11.2 % to 3.9 %,
and FCR was reduced from an average of 2.82 to 2.51. The ADWG
was improved an average of from 652.3 g/d to 705.7 g/d, and the
drug cost also reduced by an average of 13.4 yuan (2.2 USD).

CONCLUSION
In this farm, the freshly mixed combination of Ingelvac MycoFLEX®
and Ingelvac CircoFLEX® reduced the mortality rate, FCR and drug
cost, and improved ADWG by 53.4 g/d, which illustrated the superior
efficacy of the combination. Additionally, the combination made
vaccination easier for both people and pigs by reducing stress with a
single-shot injection of the two different vaccines.
