Do any of you notice a different flavor when milking bred does? We are getting an off flavor from something, almost a vinegary smell or the goaty smell/taste of some store bought goat cheeses. I seldom store milk more than 5 days with it still good on day 5, but it is getting gross by day 2? No one else is getting milk right now, just us... but yuck!!! I won't keep milking 2x a day just to throw it out! Especially the 2nd F develops dips in production levels along w/ a change in flavor during heats so I wondered if this development could be a result of pregnancy hormones. During heats you can taste a difference; now I am able to smell the flavor right away in both warm and chilled milk. They are about 50 days bred ( not tested but no more heats) ; change started about 10 days ago. I have never milked longer than 60 days bred. The 2nd F dried up immediately upon being bred last fall. This year she made it all the way to 35-40 days and is now dropping off. The other doe has more will to milk and is hard to dry off. She is still holding steady in production but has off flavored milk as well. The other possibilities that I can think of are: -cheaper brand of alfalfa pellets, still just alfalfa 17%, smells good but a little more dusty, not as greedy for them -different cutting of grass/alfalfa hay, smells good, greedy pigs on it, started feeding a week before flavor change -flavors changed exactly with the arrival of colder weather - small dry lot right next to bucks dry lot, but they have been there for 4+ weeks right through rut/breeding w/no problem They were dewormed approx. 2 months ago. A set of 3 doses of cydectin. The first dose was Cydectin/Valbazen. Same amount of grain; clean tempered water; same salt, minerals, b. soda. Normal temperatures, no hot udders or signs of mastitis, normal berries, same milking routine, milk looks fine- no strings/lumps and makes cheese as normal except for the off flavor even if the milk is pastuerized first Are there any other factors I am overlooking? Any recommendations? Thanks!
