The Association Between Non-Esterified Fatty Acids And Beta-Hydroxybutyrate During The Transition Period In Holstein Dairy Cows And Negative Downstream Outcomes - Disease Incidence, Milk Production And Reproduction
… fatty acids (NEFA) and betahydroxybutyrate (BHBA) are measurable blood metabolites used to estimate the level of NEB. The objectives of herein were to: 1) identify critical concentrations of NEFA and BHBA above which the development of diseases were more likely; 2) describe statistical …

Effects of close-up dietary energy strategy and prepartal dietary monensin on hepatic mRNA expression of enzymes involved in glucose and lipid metabolism in transition cows
… dry matter intake and analyzed serum NEFA and BHBA concentration and liver composition of the cows both prepartum and postpartum. We also examined mRNA expression at -14 and 7 via qPCR of gluconeogenesis genes (FBP1, PC, PCK1), fatty acid oxidation and ATP synthesis genes (CPT1A, ACOX1, …

Tunnutusruokinnan vaikutus lypsylehmien rehunsyöntiin ja maidontuotantoon
… insuliini- (37,4 vs. 16,7 µIU/ml, p<0,10) ja BHBA-pitoisuudet (0,59 vs. 0,36 mmol/l, p<0,05) olivat suurempia tunnutetuilla lehmillä verrattuna tunnuttamattomiin lehmiin ja NEFA-pitoisuus oli pienempi (0,16 vs. 0,23 mmol/l, p<0,05) viikko ennen poikimista. Poikimisen jälkeen veriparametreissä …

Inflamatory status and leukocyte function during the peripartum period and subsequent effects on reproduction and lactational performance in dairy cattle
… classified as either a low, moderate, or high BHBA based on their plasma BHBA concentration at 7 days postpartum. Cows were classified as low, moderate, or high haptoglobin responders at both the 7 and 28-day postpartum sampling. Plasma haptoglobin concentrations ranged from 0.88 to 1.56 g/L, …

Growth, Rumen Development, and Metabolism of Holstein Calves Fed Distillers Grains
… grains also caused linear increase in plasma BHBA and NEFA concentrations in blood. Propionic and butyric acid concentrations in the rumen fluid were decreased by feeding distillers grains, but not significantly. It is concluded that distillers grains when included in calf starters at a …

Immune function, gene expression, blood indices and performance in transition dairy cows affected by diet and inflammation
… fatty acids (NEFA) and B-hydroxybutyrate (BHBA) concentrations (Drackley et al., 2001). Prepartal level of dietary energy can potentially affect adipose tissue deposition and, thus, the amount of NEFA released into blood and available for metabolism in liver (Drackley et al., 2005). The …

Effects of close-up dietary energy strategy and prepartal dietary monensin on production and metabolism in Holstein cows
… did not affect prepartum or postpartum NEFA and BHBA concentrations. Concentrations of total lipid, triglyceride, and glycogen in liver of mature cows were not affected by treatments. . Feeding a diet of higher dietary energy density for 21 d before calving did not benefit production or …

Effects of prepartum dietary energy and lipid supplementation on hepatic transcriptome profiles in dairy cows during the transition period
… (P < 0.05) postpartal concentrations of NEFA, BHBA, and GH in serum and liver triglyceride. Those data agreed with greater expression of ACOX1, CPT1A, ACADVL, HMGCS2, FGF21, and ANGPTL4 in OVE vs. CON at 7-14 DIM. Despite the gradual increase in serum GH after calving, at 7-14 DIM liver from …

Effects of feed restriction on milk production and metabolism in mid-lactation dairy cows
… < 0.01) with its maximum on d 3 during FR. Serum BHBA increased linearly (P = 0.04) for RC (RC x d; P = 0.16) with its peak at d 4. Catabolism of amino acids (AA) increased early during FR as indicated by plasma urea N increasing (P < 0.01) quadratically (P < 0.01), with its peak on d 2 and …

Transcriptional adaptation of adipose tissue in dairy cows in response to energy overfeeding
… and greater postpartal hepatic lipid storage and BHBA production. No difference in milking performance was found between the two groups. AT biopsy was carried out on -10, 7 and 21 d relative to parturition date for RNA extraction and gene expression analysis through quantitative PCR (qPCR). Energy …

The effect of feeding frequency and alternative proteins in milk replacer on growing Holstein calves
… all blood variables except total globulin and BHBA. Scours occurred at a higher frequency for calves fed diet CON versus those fed WBP, and was greater for 2X versus 3X. Respiratory and attitude score did not (P > 0.10) differ among treatments. However, there was a greater rectal temperature …
