Effects of Concentrate Levels in Prepartum Diet on Milk Performance, Energy Balance and Rumen Fermentation of Transition Montbéliarde–Holstein Crossbred Cows

SIMPLE SUMMARY: The transition period (3 wks before to 3 wks after calving) is an important period in the lactation cycle of dairy cows. During this period, dairy cows undergo a series of physiological and metabolic changes due to the demands of pregnancy, parturition and postpartum lactation, which...

description SIMPLE SUMMARY: The transition period (3 wks before to 3 wks after calving) is an important period in the lactation cycle of dairy cows. During this period, dairy cows undergo a series of physiological and metabolic changes due to the demands of pregnancy, parturition and postpartum lactation, which can easily lead to a negative energy balance (NEB). Therefore, the energy balance and nutritional regulation mechanism of dairy cows during the transition period are the focus of dairy cow nutrition and physiology research. However, crossbred cows have received less attention to date. Our study showed that feeding a prenatal concentrate mix at a rate of 0.6% of the body weight of Montbéliarde–Holstein crossbred cows has no negative effect on the performance and rumen fermentation of postpartum dairy cows and can satisfy the energy needs of dairy cows in the prepartum period. Furthermore, our data provide a theoretical basis for further revisions to the feeding standard and to alleviate the NEB of Montbéliarde–Holstein crossbred cows in China. ABSTRACT: This study was conducted to investigate the effect of three rates of prepartum dietary concentrate feeding on the milk performance, energy balance, and rumen fermentation of Montbéliarde–Holstein crossbred cows. Eighteen transition Montbéliarde–Holstein crossbred cows with similar days of gestation (258 ± 12 day) and body weights (622 ± 44 kg) were selected and randomly divided into three groups. In the prepartum period, the addition of concentrates accounted for 0.3% (low concentrate, LC), 0.6% (medium concentrate, MC), and 0.9% (high concentrate, HC) of the cow’s body weight. The forage was corn stover, which was fed to the cows ad libitum with free access to water. Postpartum, all of the cows were fed a common lactation total mixed ration. The experimental period lasted from 21 days prepartum to 28 days postpartum. The energy balance (EB), net energy intake (NEI), and dry matter intake (DMI) of the HC group were greater than those of the other groups (p < 0.05). Likewise, the non-esterified fatty acids (NEFA), β-hydroxybutyric acid (BHBA), and total bilirubin (TBIL) in the blood of the LC group had significantly higher concentrations than they did in the other groups (p < 0.05). Moreover, the increase in the level of dietary concentrate had no significant effect on the rumen fermentation parameters (p > 0.05), and the total intestinal digestibility of dry matter (DM), crude protein (CP), and ether extract (EE) in the HC group was significantly higher (p < 0.05) than it was in the other groups during the prepartum period. In conclusion, the administration of the MC diet in the prepartum period had no negative effect on the performance and rumen fermentation of postpartum dairy cows and can satisfy the energy needs of prepartum dairy cows. Therefore, under our experimental conditions, the 0.6% prenatal concentrate feeding amount was the most appropriate for Montbéliarde–Holstein crossbred cows.
