“…Glucose levels and AST activity in our study were in accordance with normal intervals of reference values (Kaneko et al 2008) in all groups of cows. No correlations of glucose levels (De Silva et al 1981;Kappel et al 1984;Selvaraju et al 2002;Pushpakumara et al 2003) and AST (Forshell et al 1991) with fertility were found, in contrast to reported findings (Reist et al 2003). Selvaraju et al (2002) did not find differences in glucose levels between repeat breeder cows treated with insulin to increase conception rate and untreated controls.…”

“…The ability of oocytes to develop normally is related to the nutrition-dependent metabolic and endocrine status of cows (Graham et al 1995;Hazeleger et al 1995;Driancourt and Thuel 1998). Parameters of various metabolites such as glucose (Kappel et al 1984;Forshell et al 1991;Rukkwamsuk et al 2000;Westwood et al 2002), total protein (TP) (Canfield et al 1990;Shrestha et al 2005), nonesterified fatty acids (Rukkwamsuk et al 2000;Pushpakumara et al 2003), ketones Busato et al 2002;Reist et al 2003), cholesterol (Kappel et al 1984;Brantmeier et al 1987;Grummer and Carroll 1988), urea Butler et al 1996;Godden et al 2001), lipoproteins (Brantmeier et al 1987;Grummer and Carroll 1988), albumin (Forshell et al 1991;Reist et al 2003), triglycerides ((Brantmeier et al 1987) and enzyme aspartate aminotransferase (Forshell et al 1991;Zurek et al 1995;Reist et al 2002) have been studied to determine the relationships with the fertility of dairy cows. However, most of the studies have been carried out either at an early stage of lactation, before or at the first postpartum insemination, or under in vitro conditions.…”

The objectives of the study were to evaluate the morphological quality of oocytes in repeat breeder and early lactation cows and to determine the possible associations between the quality of oocytes and a range of blood metabolites. Oocyte quality and a range of metabolites were compared between 29 repeat breeder and 13 early lactation cows. The yield of oocytes from the repeat breeders was lower than that from the early lactation cows (4.4 ± 0.2 vs 5.4 ± 0.6, p < 0.05). Percentages of abnormal oocytes for the repeat breeders and the early lactation cows were 52.5% and 37.9%, respectively (p < 0.001). An excess of abnormal oocytes to normal was found in 55.2% of the studied repeat breeders (65.8% vs 34.2%, p < 0.05). Total protein, glucose and aspartate aminotransferase did not differ (p > 0.05) between the repeat breeders with an excess of abnormal oocytes (81 ± 1.0 g/l, 3.5 ± 1.0 mmol/l and 68.5 ± 3.7 U/l), those with the prevalence of normal oocytes (84 ± 1.0 g/l, 3.6 ± 0.1 mmol/l and 73.2 ± 3.5 U/l) and the early lactation cows (83 ± 2.0 g/l, 3.7 ± 0.1 mmol/l and 74.5 ± 3.6 U/I). The repeat breeders with an excess of abnormal oocytes had higher (p < 0.05) urea (5.2 ± 0.2 mmol/l) level than in those with the prevalence of normal oocytes (4.8 ± 0.2 mmol/l) and the early lactation cows (4.7 ± 0.2 mmol/l). A trend for higher total cholesterol and lactate dehydrogenase activity was found in the repeat breeders with an excess of abnormal oocytes. In conclusion, it is suggested that possible causes of repeat breeding in dairy cows may include impaired oocytes. An excess of abnormal oocytes in the repeat breeder cows was associated with elevated blood plasma levels of urea.

“…Various studies have related blood metabolites such as glucose, nonesterified fatty acids (NEFA), beta-hydroxybutyrate (BHB), albumin, urea and protein with negative energy balance and inferior animal health (Lucy et al, 1992;Spicer et al, 1990). Metabolite concentrations during the breeding season have also been found to influence ovarian function and subsequent reproductive performance (Plym Forshell et al, 1991), with positive energy balance associated with enhanced reproductive performance (Reist et al, 2003a;Snijders et al, 2001).…”

“…A negative energy balance p.p. not only contributes to increased ketogenesis (Kunz et al 1985;Ronge et al 1988;Drackley et al 1992;Bruckmaier et al 1998;Blum et al 2000), but has also a negative impact on reproductive traits, such as onset of the ovarian cycle p.p., conception at first service and time empty (Villa-Godoy et al 1988;Staples et al 1990;Butler 2000;Reist et al 2001).…”

This study aimed to assess the effect of ketone body status early postpartum on time empty in 74 multiparous dairy cows under field conditions. Animals were equally distributed across eight farms and were controlled by the same herd-fertility-monitoring programme. Cows were visited twice antepartum and six times postpartum at weekly intervals between 0530 and 0830 a.m. On these occasions, body condition scores and milk yields were measured, blood and milk samples were taken, cows were gynaecologically examined, and parameters of reproduction were recorded. Cows with a time empty of less or more than 80 days were classified as early and late conceiving cows (EC and LC, respectively). A time empty of 80 days results in calving-to-calving intervals of 1 year and classification based on this threshold value resulted in groups of equal size and equal distribution of EC and LC within farms. Ketone bodies measured were beta-hydroxybutyrate in blood and acetoacetate and acetone in blood and milk. Blood and milk ketone body concentrations, as well as the ratios of acetoacetate and acetone to beta-hydroxybutyrate, over the first 6 weeks postpartum were higher in LC than in EC, whereas plasma glucose and non-esterified fatty acids and milk fat, protein and urea concentrations did not exhibit clear differences between groups. Ketone body concentrations were as good predictors of time empty as ketone body ratios and might have practical impact in herd-fertility-monitoring programmes.
