147
Q

adults worms are a reddish color and they are about 1cm

A

STOMACH NEMATODES

  1. ostertagia ostertagi
  2. teladorsagia circumcinta
  3. hyostrongylus rubidus
148
Q

Is type 1 or type 2 ostertagiosis worse

A

TYPE 2 – winter

149
Q

what is type 1 ostertagiosis, when does it occur

A

Calves are born in the spring and have their first grazing season in the summer and fall. Since it is warm out already, there is slow emergence of the parasite and mild clinical signs occur

what is type 2 ostertagiosis, when does it occur, and when should you treat?

A

The L4 stage arrests for the winter. In the spring, there is SYNCHRONIZED EMERGENCE and the calves are yearlings. HIGH MORTALITY

**TREAT before winter/L4 arresting so they wont all come out onto the pasture :) the Tx kills L4 Stage
