We change what we feed , but remember we always tend to have quite a few goats to kid each year.
The heavy milkers who are milking now, will start to get smaller rations in September/October to encourage them to dry off if they are going to be put in kid. They continue on smaller rations until they are about 2/3 through the pregancy (at 16 weeks pregnant we start to increase food again). If we are running any milkers through, their rations stay much the same throughout the winter, but when it is very cold we increase their ration of barley and peas to help keep them warm!
The males and youngstock (ie this year's kids who will a year old next year) get quite a basic ration. When the goats that are pregnant get picky and leave some of their food, it is recycled by feeding it to the youngstock, as long as it is not dirty.
Once we get into November and our goats are not going out, this is when we rest our field for 6-8 weeks, they get extra feeds a day. They always get extra hay at lunch time, and then an extra feed at 5-6pm. The extra feed usually rotates between soaked beetpulp, alfalfa and chopped veg (cabbage, carrots and apples mostly). So from Mid-November until they all kid (usually March- early April) they get 3 feeds of food a day, plus they get hay morning and night topped up if needed, and always fresh hay at lunchtime.
The males do not always get the extra feed, especially beetpulp which we never feed to them as it can help cause kidney stones. But they will get any leftover veg, and alflafa.
Spring it all changes when they kid, once a goat has kidded, we don't give it concentrates (mix) for at least 3 days afterwards, they get alflafa, veg, bread, barley, peas etc instead. then we gradually introduce back in the protein again. We slowly increase their rations, not giving them full rations until they have been kidded for 6 weeks. 6 weeks after kidding is when their milk production should peak, and you will have to feed according to their condition and the amount of milk they are producing.
That may be a longer answer than you bargained for Langdon!!!
