Metabolic profiles in five high-producing Swedish dairy herds with a history of abomasal displacement and ketosis

Abstract

Background: Body condition score and blood profiles have been used to monitor management and herd health in dairy cows. The aim of this study was to examine BCS and extended metabolic profiles, reflecting both energy metabolism and liver status around calving in high-producing herds with a high incidence of abomasal displacement and ketosis and to evaluate if such profiles can be used at herd level to pinpoint specific herd problems.

The comparison of propylene glycol and glycerol as feed additives in early lactation of high producing dairy cows

“…Energy deficiency in cows is apparent from a decreased concentration of glucose that is under the reference limit of 3.0 mmol · l -1 (Hofírek et al, 2009) and increased concentration of total ketone bodies above 1.0 mmol · l -1 (Hofírek et al, 2009) in both groups during whole experimental period. The extent of mobilization of body lipids is seen from the increased concentration of NEFA in blood serum above the values recommended for fresh cows, 0.7 mmol · l -1 (Stengarde et al, 2008). The concentration of NEFA was increased by similar extents in both groups during the entire three weeks of the experiment.…”

“…Selected indicators of ruminal fermentation 3 weeks after parturition in group receiving 500 ml of glycerol (G1, n = 9) or 300 ml of propylene glycol (P1, n = 9) and in group receiving 1000 ml of glycerol (G2, n = 9) or 300 ml of propylene glycol (P2, n = 9) Table 2. Selected indicators of metabolism during 3 weeks after parturition in group receiving 500 ml of glycerol (G1, n = 9) or 300 ml of propylene glycol (P1, n = 9) .45 ** P < 0.01 * P < 0.05 -between groups G1 and P1 esterified fatty acids, which were increased in relation to the values recommended for fresh cows, 0.7 mmol · l -1 (Stengarde et al, 2008) in both groups in the first two weeks after parturition. The concentrations of glucose in both groups were within the reference limits during the whole experiment.…”

NMR-based metabolomic evaluation in dairy cows with displaced abomasum

“…In general, NEFA is a better predictor of negative downstream outcomes; however, BHB is easy and inexpensive to measure accurately, cow-side, if the appropriate test is chosen (18). NEFA was the parameter that most closely reflected body condition losses, while these losses were not seen in glucose and fructosamine levels (19). In the present study the biochemical parameters, in accordance with the above-mentioned references and our previous work (20,21), reflected a negative energy balance.…”

Acute Phase Proteins, Clinical, Hematological and Biochemical Parameters in Dairy Cows Naturally Infected with Anaplasma Marginale

“…The manufacturer of this assay reported a limit of detection in bovine serum of 0.25 mg/L. Cutpoints for serum haptoglobin of >150 mg/L or >500 mg/L have been recommended to identify an acute phase response in postparturient dairy cows, and >670 mg/L was recommended to identify cattle with traumatic reticuloperitonitis 16,23,24 . Estimated values for sensitivity and specificity (versus clinical examination as the gold standard) for a cutpoint of serum [haptoglobin] of >150 mg/L are 0.83 and 0.58, respectively 25 .…”
