“…However, increased DMI accounts for only about half of the milk yield response to selection (Patton et al, 2007). Other factors explaining the increased milk yield with HMP diet could be a possible reduction in prepartum protein mobilization (Bell et al, 2000;Stockdale and Roche, 2002;Amirabadi Farahani et al, 2017) coupled with lower postpartum concentrations of BHB and FFA (Carlson et al, 2006). The increasing trend in milk protein yield over the 9-wk period with the HMP diet further supports the literature showing adequate MP supply during the prepartum period could increase the postpartum AA availability for milk protein synthesis (Bell et al, 2000;Larsen and Kristensen, 2013;Kokkonen, 2014).…”

An experiment was conducted to determine the effects of low and high metabolizable protein (MP) diets when fed for ad libitum and controlled intake during the prepartum period on postpartum lactation performance and feeding behavior of dairy cows. Thirty-six multiparous Holstein cows were blocked by parity, expected calving date, and previous lactation milk yield at −21 d relative to expected calving and were randomly assigned to 1 of 4 close-up period dietary treatments providing low MP (LMP) or high MP (HMP) diets with controlled intake (CNI) or ad libitum intake (ALI). The concentrations of MP were 65 and 90 g/kg dry matter for LMP and HMP diets, respectively, whereas intake was controlled to supply 100 and 160% of the NRC (2001) energy requirements for CNI and ALI groups, respectively. The concentration of net energy for lactation (NE L ) in the treatment diets was 1.50 Mcal/kg. All cows were fed a similar lactation diet after calving (1.50 Mcal/kg of NE L and 83.3 g/kg of MP). The HMP diet increased dry matter intake during the first 3 wk and tended to increase dry matter intake over the 9 wk of lactation. Meal size and eating rate increased in the ALI cows during the prepartum period. Meal frequency increased with the HMP diet during the postpartum period. Milk yield increased by 15.2% with the HMP diet over the 9 wk of lactation. The HMP diet increased energy-corrected milk (ECM) yield in CNI versus ALI cows, whereas the LMP diet increased ECM yield in ALI versus CNI cows over the 9 wk of lactation. The increase in ECM yield of LMP-ALI versus LMP-CNI cows was supported by greater body condition loss and serum β-hydroxybutyrate over the 9 wk of lactation.Taken together, these data indicate that prepartum controlled intake of a high protein diet can provide the benefits of both strategies.

“…The nutrient requirement of pregnant and lactating mammals is justified both from quantitative and qualitative aspects (Van Saun and Sniffen, 1996;Carlson et al, 2006). High-yielding dairy cows are especially responsive to the energy content of the diet (Agnew and Yan, 2000).…”

In a model experiment, Holstein-Friesian dairy cows were fed on a cornsilage-based diet supplemented with 11.75 MJ NE l per day of calcium soaps of palm oil fatty acids (CAS) or hydrogenated triglyceride (HTG) or without fat supplementation (control). All diets were fed to the cows over a period from 21 ± 3 days (d) prior to the expected calving to d 100 ± 5 postpartum. On d 25 (basal sample) and d 14 prepartum as well as on d 5 and 25 postpartum liver samples were collected by percutaneous biopsy. Total lipid content, fatty acid composition and glycogen of liver tissues were determined. At d 5 postpartum, both control and CAS cows had higher liver lipid (P < 0.05) and lower glycogen (P < 0.05) concentrations than cows in the HTG group. No significant (P < 0.05) differences were detected in liver fat content among the groups at d 14 prepartum or d 25 postpartum. The glycogen concentration slightly decreased in the liver of cows in each treatment group from d 14 prepartum to d 5 postpartum; however, this decrease was more intensive in both the control and CAS groups than in the HTG group. The variations in liver lipid concentrations were accompanied by significant changes in the proportion of C16:0, C16:1n-7, C18:0, C18:1n-9, C18:2n-6 and C20:4n-6 fatty acids in the liver lipids. The results show that HTG supplementation exerted more advantageous effects on liver lipid and glycogen metabolism than did CAS supplementation.
