From: Dietary citrulline supplementation enhances milk production in lactating dairy goats
Daily milk production (L/d) by goats differed among days of lactation. Data were analyzed using ANOVA for a repeated-measures model and the Student-Newman-Keuls multiple comparison test [21]. Milk yield on d 40 of lactation was greater than that on d 0 (n = 47; P < 0.0001) and d 10 (n = 47; P < 0.05) of lactation. Milk production on d 20 of lactation was greater than that on d 0 (P < 0.0001) of lactation, and milk yield on d 10 of lactation was greater than that on d 0 of lactation (P < 0.0001). Asterisks indicate that means differ from one another (*P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001). Error bars represent SEM
