<![CDATA[This study aimed to evaluate the relationship between Crude Protein (CP), Total Digestible Nutrient (TDN), and Calcium (Ca) intake in dry-stall dairy cows on birth weight and body size of Holstein Friesian calves. The study used an observational method with purposive sampling of dry-stall Holstein Friesian dairy cows in the early 8th month of gestation with parity 2–7. The parameters observed included CP, TDN, and Ca intake of the dams during the dry-stall period as well as birth weight, chest circumference, height, and body length of the calves. Data were analyzed using multiple regression to determine the relationship between variables. The results showed that the average intake of TDN, CP, and Ca was 8.03 kg/head/day, 1.52 kg/head/day, and 63 g/head/day, respectively. The average birth weight of calves was 38.89 kg with body measurements of 81.64 cm chest circumference, 78.92 cm height, and 70.82 cm length. Intake of TDN and CP together was significantly related to birth weight and chest circumference of calves, but not significantly related to height and length. Ca intake did not show a significant relationship to birth weight or body size of calves. Based on the results of the study, it can be concluded that the intake of CP and TDN of dairy cow in the dry phase of the pen is positively related to the initial performance of calves as reflected in birth weight and chest circumference, while the intake of Ca of the mother in that phase is not directly related to calf performance at birth.]]>
