“…The reference values of BHBA levels are between 0,2 -0,8 mmol/L. 15 But in this study, BHBA values had statistically significant differences between breeds. However, breeds are important to evaluate the value of BHB, which is the gold standard for determining the negative energy balance.…”

The objective of this study was to determine the differences between the healthy Holsteın-Friesian, Jersey, Simmental, and Aberdeen Angus breeds Beta-hydroxybutyrate (BHBA) levels at the first three weeks after calving. The blood samples were collected for analysis between 10-20 days postpartum. In this study, 80 animals were used in different regions in total. BHBA was analyzed by Ketosite®( Ketosite®, Stanbio Labrotory Inc., Boerne, TX USA). Milk fat and protein levels were immediately measured by an electronic milk analyser (Milkoscan FT1 FOSS industries, Denmark). Statistical analyses of the study were performed using Sigma Plot 12 ( Systat Software Inc., San Lose, CA). The means of BHBA levels were compared by One Way Anova. As in Holstein cows, blood BHBA levels increased in the early lactation period and also in other breeds. The results of this study presented that serum BHBA levels were significantly higher in Holsteın-Friestein cows than in Simmental and Aberdeen Angus cows.

“…Blood parameters, including NEFA, BHB, and cholesterol, have been shown to reflect the energy balance of dairy cattle and are often included in routine tests for transition cows (Kida 2003, Stengärde et al 2008. BHB is one of the major ketones, and NEFA concentration reflects the mobilization of lipid reserves (Oetzel 2007, Ospina et al 2010. High levels of both are associated with a higher incidence of periparturient metabolic diseases such as ketosis or fatty liver (Bobe et al 2004).…”

During the transition period, the cow's body activates adaptive mechanisms aimed at adjusting to the changing demand for energy and nutrients, which are necessary for the growing fetus and the subsequent start of milk production. This time is also associated with an increased risk of metabolic diseases and reproductive disorders.Our study aimed to identify prepartum and postpartum biochemical markers and weight loss patterns that could differentiate cows that would exhibit ultrasonographic signs of liver fatty infiltration during the latter half of the transition period.The study was performed in a single herd of Holstein-Friesian cows and the animals were divided into two groups: CON (n=13) -cows without ultrasonographic signs of fatty liver, and FL (n=16) -cows with ultrasonographic signs of fatty liver. Backfat thickness and specific biochemical parameters were measured weekly from one week before parturition to 9 weeks postpartum.Our study highlights the importance of using a combination of monitoring methods to assess the metabolic status of transition dairy cattle. The results showed that ultrasound measurements of backfat thickness, blood NEFA levels, glucose concentration, and AST activity were all different (p<0.05) between the control and FL groups, indicating the usefulness of these parameters in monitoring the health status of transition cows. Additionally, the results suggest that high prepartum glucose levels (4.99 mmol/l) could serve as a potential marker for future FL, while the elevated NEFA levels (0.51 mmol/l) and decreased AST activity (80.56 u/l) in FL animals indicate their potential as indicators of lipid mobilization and liver structural damage, respectively.

This study aimed to evaluate non-esterified fatty acids (NEFA), beta hydroxybutyric acid (BHBA), magnesium (Mg2+), calcium (Ca2+) and lactate as biological tests for the detection of some metabolic diseases during transition period in selected dairy farms located in Aydın province. Cow-side analysis with body condition score evalutation were performed weekly in at least 12 dairy cattle from each farm from prepartum week 2 to postpartum week 2. According to the prepartum NEFA ≥0.4 mmol/L, postpartum BHBA ≥1.4 mmol/L and Ca2+ ≤ 2.0 mmol/L at parturition (day 0) in herd-based evaluation, it was observed that all farms were positively evaluated for negative energy balance and also at risk for subclinical hypocalcaemia. Regarding the threshold value of Mg2+ <0.61 mmol/L, subclinical hypomagnesaemia was observed at the Ist and IInd farms. It was concluded that prepartum NEFA threshold (0.68 mmol/L), obtained from the receiver operating characteristics statistical analysis could be used for observing some postpartum clinical diseases. It was suggested that it allowed planning and strategic interventions to prevent herd-based diseases in Turkey and will be a precedent for future studies and herd management.
