The genetic potential of dairy goats to produce milk and fat can be improved each generation if the does and bucks with the best genetypes in the current generation are selected as parents for the current generation.The practical difficulty in mating the best to the best,is to know which does and bucks are the best.KEEP RECORDS.The reproductive performance of goats can be exceptionally high.Birth rates of 98% over 2 estrous cycles with an average of 1.5 kids have been reported.Such fertilty is probably due to maximizing proper management.Reproductive management of dairy goats involves three periods:
1-the breeding season
2-the pregnant and dry period
3-kidding time
