split litters

This is still not the case. Just a little repro lesson, not to be mean or to make anyone mad. Only one ovary ovulates at a time and in litter bearing species (hog,dog, ect) the ovary has many more follicles which release eggs than in a one or two offspring animal. This process of multiple follicles releasing eggs is mimiced when a high producing cow is flushed. In the process, hormones are given to superovulate the cow that would maybe normally only drop a couple eggs now forms many follicles and drops maybe in the vicinity of 20. These eggs are fertilized and then flushed out seven days later. This same process of split flushes can be done, but in the end is more trouble because the embryos or calves out of this kind of flush would then have to be DNA tested to make sure which mating it truely is. Doesnt hurt to learn a little every now an then now does it.
