Goat production is one of the key elements contributing to the economy of farmers living in the arid and semi-arid regions, including most areas of Iran. In general goat meat production as whole does not meet the consumption demands in many developing countries. Goat meat is generally highly nutritious and has taste that is well-established in many cultures. Rapid growth during the early period can minimize the cost of rearing and thus provide more profit to the farmer. The birth weight and early growth rate of animals are determined not only by genetic potential but also by maternal and environmental factors (Mandal et al., 2006). The objective of this study is therefore to find the factors affecting birth weight in Iranian indigenous breed.
