“…This observation agrees with other studies which compare the glucose levels of Holstein and crossbred cows. Pellizza et al [ 33 ] reported no difference in glucose levels by comparing Holstein and crossbred Holstein × Jersey cows. Glucose records ranged between 59 and 63 (mg/dl) for both genetic groups.…”

“…The majority of studies evaluating the transition period of dairy cows were performed with the Holstein breed [ 29 , 30 , 31 ]. A number of studies evaluated Holstein × Montbeliarde, Holstein × Jersey or Holstein × Simmental crossbred cows in comparison with one of the parental breeds (most often Holstein) [ 4 , 32 , 33 , 34 ]. Only a very few studies compared crossbred Holstein × Simmental cows and both parental breeds [ 12 , 35 ].…”

Crossbreeding in dairy cattle has been used to improve functional traits, milk composition, and efficiency of Holstein herds. The objective of the study was to compare indicators of the metabolic energy balance, nonesterified fatty acids (NEFA), beta-hydroxybutyrate (BHBA), glucose, body condition score (BCS) back fat thickness (BFT), as well as milk yield and milk composition of Holstein and Simmental cows, and their crosses from the prepartum period until the 100th day of lactation at the Livestock Center of the Ludwig Maximilians University (Munich, Germany). In total, 164 cows formed five genetic groups according to their theoretic proportion of Holstein and Simmental genes as follows: Holstein (100% Holstein; n = 9), R1-Hol (51–99% Holstein; n = 30), first generation (F1) crossbreds (50% Holstein, 50% Simmental; n = 17), R1-Sim (1–49% Holstein; n = 81) and Simmental (100% Simmental; n = 27). The study took place between April 2018 and August 2019. BCS, BFT blood parameters, such as BHBA, glucose, and NEFA were recorded weekly. A mixed model analysis with fixed effects breed, week (relative to calving), the interaction of breed and week, parity, calving year, calving season, milking season, and the repeated measure effect of cow was used. BCS increased with the Simmental proportion. All genetic groups lost BCS and BFT after calving. Simmental cows showed lower NEFA values. BHBA and glucose did not differ among genetic groups, but they differed depending on the week relative to calving. Simmental and R1-Sim cows showed a smaller effect than the other genetic groups regarding changes in body weight, BCS, or back fat thickness after a period of a negative energy balance after calving. There was no significant difference for milk yield among genetic groups, although Simmental cows showed a lower milk yield after the third week after calving. Generally, Simmental and R1-Simmental cows seemed to deal better with a negative energy balance after calving than purebred Holstein and the other crossbred lines. Based on a positive heterosis effect of 10.06% for energy corrected milk (ECM), the F1, however, was the most efficient crossbred line.

“…A treatment with 5-hydroxytryptophan (the immediate precursor to serotonin synthesis) could actually decrease the BHB concentration at days 6-10 postpartum, what might lead to a more stable energy homeostasis, particularly in Jersey cows (Weaver et al 2017). By comparing Holstein with crossbred Holstein x Jersey cows at two weeks before and eight weeks after calving, Pelizza et al (2019) did, however, not find any difference between the breeds for BHB. They reported a difference between transition periods with higher BHB values after calving.…”

“…Block e Litherland (2013), a dieta aniônica é uma forma de se evitar a hipocalcemia clínica e subclínica. Animais que apresentam hipocalcemia subclínica tendem a ficar mais susceptíveis a doenças, como febre, metrite, retenção de placenta, além de redução da função de células (PELIZZA et al, 2019). O fornecimento de dietas aniônicas 30 dias no pré-parto evita falhas na homeostase de cálcio e no pós-parto previne quadros de hipocalcemia (SEIFI et al, 2010).…”
