外文摘要：The primary fortitude of this study is to overview the environmental, nutritional and also some main infectious causes related to reproduction in small ruminants mainly sheep and goat, that caused milk, meat and wool production loss globally. Mostly 90% small ruminants are reared by rural household globally. The major issues of which are poverty, lack of new techniques and improper management skills. Families usually own few small ruminants, which are used for religious celebrations, serve as savings or emergency cash or provide meat or milk. Reproductive problems mainly arise due to nutritional deficiencies and some pathogens, including bacteria, viruses, parasites and also by environmental stress conditions. The primary reproductive diseases which are commonly associated with the reproductive system of small ruminants are brucellosis, leptospirosis, toxoplasmosis fever, listeriosis, campylobacteriosis along with nutritional deficiencies, socio-sexual and photoperiods also affect the reproductive system. Vaccination and nutrition are mainly advised to control these issues of reproduction. The environment control system can also compensate for this economic loss. This paper represents a limited contribution for the review of reproductive problems in small ruminants' primarily focusing on sheep and goat which was neglected in past at worldwide level.
