Have your goats fecal tested and worm based on their needs. One wormer doesn't take care of all worms. Most people don't just worm on a schedule because you really aren't sure which worm you have an abundance of at any given time and you don't want to over worm as that will make the wormer less effective over time.
If you want to do a continuous worming then consider herbal wormers as a preventative.
we dont worm unless they need it..a fecal will help determine if they need wormer..other ways to tell if you can't do a fecal are:
Coat condition: coarse, fuzzy,dull, or sleek and shiny
Eyes: lower inner lids are bright pink to red or pale or white
gums: pink or pale?
Condition: loosing weight, or at healthy weight
Growth: growing well including horns, stunted growth.
sometimes we have to go by what we see if fecal cant tell us the story
good wormer for kids is valbazen..it get tape worms and liver fluke where others do not..and its oral : )
worms I do treat for; Cocci: I use Baycox at 3 weeks old..then as needed..dimethox and sulmet are good OTC choices
baycox is ordered from horseprerace.com..
Safe guard is not an effective wormer imo...if you like oral, valbazen is good for all goats except pregnant ones....valbazen and Ivomec plus are the only wormers effective against liver fluke....Liver fluke does not show up in a regular fecal..better to use a wormer that covers LF as well as most worms goats deal with...
