1.	What can heart girth measurements of cows be used to estimate?(a) Age(b) Milk production(c) Calving date(d) Body weightThis question was posed to me in an international level competition.My question is taken from Cattle Health in chapter Cattle Health of Dairy Engineering
Answer» Correct option is (d) Body weight Best explanation: Circumference of a chest (heart girth) has been found to be the measurement most CLOSELY correlated with weight. The Dairy Cattle Research Branch2 of the U.S.D.A. reported a table of heart girth weight EQUIVALENTS from which a measuring TAPE was prepared. This tape has been used EXTENSIVELY for more than 20 years in connection with D.H.I.A. work and for the ESTIMATION of body weight in dairy cattle generally.
