When we got home from our trip to Oregon to see the eclipse (WOW amazing sight and a great family vacation), I noticed that one of our mama goats, Polly, had become skeletally thin. She has always been a slender goat. Some
goats are naturally thin, some are naturally plump, just like
people. However, Polly's condition was in no way normal - her bones were sharp and visible from a distance.
There are many factors that contribute to weight loss on goats. One of the main ones - insufficient feed- is not an issue at my place because I have three acres of fenced pasture for three does to feed in, more than enough. Probably the most important factor after availabalility of feed is parasite load.
Goats are particularly prone to parasites. They are a problem in every area of the country. There are a plethora of parasites - stomach worms, lung worms, coccidia. For the most part, parasites will not kill an otherwise healthy goat, but they will seriously depress her ability to produce healthy kids, abundant milk, and keep her own health intact. https://www.famu.edu/cesta/main/assets/File/coop_extension/herds/Practical_Management_Internal_Parasites_in_Goats1_7-23-2007.pdf
I use ivermectin to control parasites, but over the years I think my herd has built up some resistance, because this year ivermectin is not showing much effectiveness. In particular, my best doe, Polly, has lost a tremendous amount of weight while raising her twins.
The caloric cost of nursing twins is, of course, very high, but a healthy doe with unlimited forage ought to be able to do it without losing condition. Polly has been losing weight, and when we got back from our five day trip to see the eclipse (AWESOME!!) she had suddenly become emaciated.
I worked her again, with Ivermectin as usual and also with Quess, a different wormer which has a different mode of action. Hopefully that will have an effect, but in the meantime I needed to get those kids off of her. They have been sucking her dry.
We have three kids left - Polly's twins and a single doe from Christmas. They are all of an age to have been weaned a month ago, at least, but I am softhearted and didn't want to separate them from their mamas. Well, Polly's condition forced my hand. Two nights ago, I put all the babies into the sacrifice area. Such wailing! Such gnashing of teeth! Anyone would think they were being peeled alive. But no- they are just being weaned.
All three babies are seriously overweight. Obese even. They have "milk glitters" on their throats- signs that they are being over fed. And meanwhile their poor mamas are staggering around at the end of their endurance. I should have separated them a month ago.
