Efficacy of a novel bivalent vaccine containing porcine circovirus type 2d and Mycoplasma hyopneumoniae against a dual PCV2d and Mycoplasma hyopneumoniae challenge.

ABSTRACT:

Background

Information on efficacy of a novel bivalent vaccine containing porcine circovirus type 2d (PCV2d) and Mycoplasma hyopneumoniae.

Objective

To evaluate bivalent vaccine for efficacy under experimental conditions.

Animals

Clinically healthy 35 weaned piglets at 18 days of age were used.

Methods

A 2.0 mL dose of bivalent vaccine was administered intramuscularly to pigs at 21 days of age in accordance with the manufacturer's instructions. The pigs were challenged at 42 days of age either intranasally with PCV2d, or intratracheally with M. hyopneumoniae, or with both.

Results

Vaccinated-challenged pigs improved the growth performance compared to pigs that were unvaccinated and then, challenged. Vaccinated-challenged pigs elicited a sig
