خلاصه	Animal BLUP (Best Linear Unbiased Predictor) is a statistical method for estimating the genetic merit (breeding values) of livestock based on their own performance and the performance of their relatives. Developed by Charles R. Henderson in 1949 and refined continuously since, Animal BLUP accounts for pedigree relationships, environmental effects, and non-additive genetic variance, providing accurate predictions of an animal's ability to transmit desirable traits to offspring.	Body Condition Scoring (BCS) is a semi-quantitative visual and palpation assessment method used to evaluate the nutritional status and adipose tissue reserves of livestock, particularly dairy cattle, beef cattle, and small ruminants. Developed systematically in the 1980s, BCS provides a practical, non-invasive tool for herd management, reproductive performance prediction, and feed efficiency optimization.	Polysomnography (PSG) is a comprehensive multi-channel physiological recording method that simultaneously records brain electrical activity, eye movements, muscle tone, respiratory effort, oxygen saturation, heart rate, and limb movements during sleep. First systematized by Rechtschaffen and Kales in 1968, polysomnography is the gold standard for diagnosing sleep disorders, characterizing sleep architecture, and assessing the quality and organization of sleep in humans and increasingly in veterinary species.
