![]() Further, we briefly discuss the relationships between BCS and ram performance and animal welfare. The role of BCS in milk production and lamb growth is also reviewed. We then discuss and compare studies that have investigated the relationships between BCS and reproductive success, and examine the impact of BCS on every step of the reproduction process in ewes. ![]() In this review, we first describe the methods used to assess BCS and how this assessment relates to live weight (LW) and direct fat deposition measurements. The BCS technique has the potential to be a useful management tool for producers to lift animal performance. However, the subcutaneous and muscle reserves along the backbone can be assessed using the body condition scoring (BCS) technique, which is described below, and forms the basis for this review. Reserves located in the abdominal cavity, such as glycogen in the liver and intra-abdominal fat, cannot be assessed easily on live animals without specific equipment. An animal's total body nutrient reserves are difficult to measure or assess. It is apparent that when nutrient supply is limiting, or when feed demand is high, animals, including sheep, will utilise their body reserves in an attempt to meet their requirements. ![]() Although all nutrients are ultimately derived from food intake, the pool of disposable nutrients in an animal includes those that are stored in body tissues, such as adipose tissue and intramuscular fat, that can be mobilised if required (Rauw Citation2008). ![]()
