Effect of prepartum diets on energy balance (Mcal/day) during last 4 weeks of gestation and second week postpartum. Thirty-one cows (n = 10 or 11 per treatment) were fed experimental diets during the last five weeks of gestation. Prepartum diets did not influence the energy balance during last 4 weeks of gestation (a). The average of energy balance during last 4 weeks of gestation was 9.92 ± 1.05, 8.44 ± 1.08 and 7.11 ± 1.22 Mcal/day in canola, control and sunflower, respectively. Regardless of treatment effect, energy balance during last week of gestation was significantly reduced compared to wk–4, –3, and –2. Prepartum diets significantly affected postpartum energy balance during the second week (b). Cows fed control diet had a more pronounced negative energy balance than those fed diets supplemented with canola or sunflower. Energy balance was significantly higher on Day 14 than on Days 11, 10, 9 and 8
