[QUOTE="milkmaid, post: 465985, member: 852"] Couple thoughts on the article, Larry... 1) he says, "When you see a calf with pneumonia, the problem developed two weeks ago." IMO, in some cases, yes... however, I've seen a few too many develop pneumonia at 1-2 days old to believe that one started two weeks ago. 2) he says, "My current calf program uses Immunoboost on Day One and Day Eight in lieu of the MLV vaccine. Interferon is produced with in two hours following an injection of Immunoboost and the interferon lasts for seven days at a much higher level than is obtained with the MLV vaccine." So he finds that using a immune system stimulant at the beginning works better than using a vaccine that initally supresses the immune system. Big surprise. 3) he says, "Do I vaccinate sick calves? I certainly do. I have tried waiting until the calves looked good to vaccinate, and I never seem to find that time period." That's just a time management problem. Or else a management problem that he can't get them to ever look good. 4) he says, "It is important to realize the vaccine causes an immune response in the calf and it will run a fever after injection. A calf with a fever may not want to eat well. So the day after vaccinating with an MLV, the calf will look worse. The second day post vaccination the calf looks about like it did the day of vaccination. By the third day the calf is usually up and running." IMO one has to take into consideration the condition of the calf. It is perfectly possible that the immune system may mount a valiant response to being severely stressed, but you may well take the calf down so far you kill him before his immune system achieves an adequate defense. quotes from [url=http://www.calfdoctor.com/NSL/NSL05/Jan05NSL.html]http://www.calfdoctor.com/NSL/NSL05/Jan05NSL.html[/url] Some of what he says in there is good, but I'm not sure I agree with everything he says.
