Subclinical Hypocalcaemia

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.

Peak Lactation

A significant factor in improving the performance of dairy cows is their physiological ability to correct a negative energy balance (NEB). This study, using Simmental (SIM) and Holstein-Friesian (HF) cows, aimed to assess changes in NEB (non-esterified fatty acid; body condition score; and C16:0, C18:0, and C18:1) and its effect on the metabolic efficiency of the liver (β-hydroxybutyrate and urea). The effects of NEB on daily yield, production at peak lactation and its duration, and changes in selected milk components were assessed during complete lactation. Up to peak lactation, the loss of the body condition score was similar in both breeds. Subsequently, SIM cows more efficiently restored their BCS. HF cows reached peak lactation faster and with a higher milk yield, but they were less able to correct NEB. During lactation, their non-esterified fatty acid, β-hydroxybutyrate, C16:0, C18:0, C18:1, and urea levels were persistently higher, which may indicate less efficient liver function during NEB. The dynamics of NEB were linked to levels of leptin, which has anorectic effects. Its content was usually higher in HF cows and during intensive lactogenesis. An effective response to NEB may be exploited to improve the production and nutritional properties of milk. In the long term, it may extend dairy cows’ productive life and increase lifetime yield.

Metabolic Challenge

The transition from pregnancy to lactation (i.e. the transition period) is a time of significant metabolic challenge, with a several-fold increase in a cow’s requirement for energy, protein and minerals within days of calving. A successful transition involves the initiation and coordination of changes in multiple tissues that facilitate the provision of these nutrients to the cow and, more specifically, to the mammary gland, often at the considerable expense of other tissues. Failure to coordinate the necessary changes effectively results in transition period maladaptation, which can broadly be grouped into three categories: (1) negative energy balance and metabolic diseases associated with energy metabolism; (2) immune dysfunction and inflammation; and (3) metabolic diseases associated with mineral deficiency. Because reinitiation of ovarian activity, follicle recruitment, ovulation, fertilisation and, potentially, even maternal recognition of pregnancy and implantation occur against the backdrop of this metabolic and immunological disturbance in early lactation, the role of nutrition in ensuring a smooth transition between the pregnant and lactating state is important. In this paper we integrate recent research findings with previous knowledge of the interaction between transition cow metabolism and nutrition and reproductive outcomes, and offer new insights into key elements of successful cow management to avoid transition ‘maladaptation’ and improve pregnancy rates.

The aim of the present study was to evaluate the potential for diagnosis of fatty liver by means of ultrasonographic measurement of liver and perivisceral adipose tissue as an alternative to blood indicators of lipomobilization and liver biopsy in periparturient high-yielding dairy cows. Thirty cows were enrolled and divided into two groups. The evaluation of body condition score (BCS), non-esterified fatty acids (NEFA), β-hydroxybutyrate (BHB), liver and perivisceral adipose tissue ultrasonographic measurement and histological liver lipid content (GdL) was performed at 15 ± 5 d prepartum (T0), 10 ± 2 d postpartum (T1), 30 ± 2 d postpartum (T2) and 50 ± 2 d postpartum (T3). Mesenteric fat thickness (the thickness of the perivascular adipose tissue) measured on ultrasound was shown to be an independent determinant of fatty liver. The cut-off of the ultrasonographic evaluation of the liver may be useful as a first and practical approach in identifying fatty liver. In conclusion, a non-invasive and reliable diagnostic method for predicting the risk of fatty liver in high yielding dairy cows has been demonstrated.

Grazing Dairy Cows

The transition period of the dairy cow generally refers to the last three weeks of gestation and the first three weeks of lactation. During this period, the dairy cow faces numerous physiological challenges, requiring both homeostatic and homeorhetic changes to support the demands of lactation. Management strategies to achieve a successful transition have developed over many decades. Historically, these strategies focussed on achieving high energy intakes pre-calving in an attempt to improve post-calving metabolism; however, more recent research has indicated that this approach may not be appropriate. Physiological and molecular data have indicated that imposing a slight negative energy balance (EBAL) pre-calving can improve post-calving EBAL, metabolic health indices and milk production. It was hypothesised that the challenges of the transition period would be less in a grazing system than in an intensive confinement system, due to the lower milk production and the difference in population density and, therefore, pathogen exposure. However, the molecular and immunological responses to the change of state are similar in magnitude in a moderate-yielding pasture-fed cow and in a high-yielding cow fed a total mixed ration. The collective data point to a peripartum immunosuppression, which is affected by body condition score and feeding level. This review will outline the literature and provide an assessment of the most recent transition cow management for grazing dairy cows.

The body condition score (BCS) at calving has been postulated as the main factor in the interaction of nutrition and reproduction in beef-cow ecosystems. The objective of the present study was to analyse the effect of BCS at calving on endocrine and metabolic profiles during the transition period in primiparous Hereford cows (n = 56) grazing native grassland. Cow BCS was registered and plasma insulin, insulin-like growth factor-I (IGF-I) and metabolites (concentrations of urea, albumin, cholesterol, total protein, non-esterified fatty acids (NEFA)) were determined in plasma from –30 to +45 days postpartum (DPP). The effect of BCS at calving (low ≤3.5 and moderate ≥4; 1–8 visual scale) on BCS evolution and hormone and metabolite concentrations were analysed using a time repeated-measures analysis. Cow BCS, NEFA, urea and IGF-I profiles were affected (P < 0.05) by the BCS at calving and DPP interaction, while insulin tended (P = 0.06) to be affected only by BCS at calving. The low-BCS cows presented a smaller loss of BCS during the prepartum than did moderate-BCS cows, and a delayed BCS recovery during the postpartum. The increase in plasma NEFA was greater (P < 0.05) and started earlier during the prepartum period in the low-BCS cows. Protein concentrations increased during prepartum to +30 DPP, while albumin and urea concentrations were maintained until calving and decreased during the postpartum. Urea concentrations were greater (P < 0.05) during prepartum in low-BCS cows. Concentrations of IGF-I and insulin were greater (P < 0.05) in moderate- than low-BCS cows during prepartum, but did not differ between the groups after calving. No effects were observed in calf weight or milk production at +45 DPP. The association between BCS during prepartum and at calving with the endocrine and metabolic profiles (positive: insulin, IGF-I; negative: NEFA and urea) reflected a better nutritional status and plasticity to negative energy balance on moderate cows. This different endocrine milieu did not affect calf weight and/or milk production. In conclusion, the BCS at calving affected the metabolic and endocrine profile during the transition period of primiparous beef cows grazing native grassland.

Data were obtained from 89 Holstein cows, distributed among seven commercial herds, to evaluate the incidence of metabolic disorders during the periparturient transition period. The herds were enrolled in the Dairy Herd Improvement Program (DHIP) and were routinely visited by veterinarians, who diagnosed any metabolic disorders. The cows were observed every two weeks to evaluate body condition score (1 to 5 scale), to discern clinical disorders and to obtain blood samples for chemical analyses. Clinical metabolic diseases were not diagnosed, but 34% of the cows showed sub-clinical hypocalcaemia (blood calcium less than 7.9 mg/dl) and 14% had blood glucose levels less than 39.9 mg/dl. Although not significant (P greater than 0.05), milk production was higher at the second and third milk weighings in the normal cows than in those with sub-clinical hypocalcaemia (27.5 and 25.6 vs. 25.1 and 23.6 kg, respectively). The interval between parturition and first service was shorter in cows with normal blood calcium levels than in those that suffered sub-clinical hypocalcaemia (74 vs. 91 days, P less than 0.05). Mean body condition score of the cows without sub-clinical hypocalcaemia or sub-normal blood glucose levels was higher than that of cows with these conditions (2.5 vs. 2.3 in both criteria, P less than 0.05). It is concluded that postpartum blood calcium concentrations affect the interval from parturition to first service and that the probability of occurrence of hypocalcaemia after parturition can be estimated from prepartum blood calcium concentrations.

Abstract. The aim of this study was to compare the influence of propylene glycol and glycerin added to Total Mixed Ration (TMR) dose on lipid-carbohydrate metabolism, activity of selected liver enzymes and milk yield of Simmental cows in periparturient period. Forty two cows of Simmental breed were divided into 3 groups (n=14). Cows from the experimental groups were given 300 ml/d of either propylene glycol or glycerin from 7th day prepartum to 21st day postpartum. In week 5 of lactation in cows that were given propylene glycol and in week 12 in cows receiving glycerin Body Condition Score (BCS) was higher as compared to control cows. An application of glycerin resulted in the highest milk yield. Higher glucose content in groups that were given propylene glycol and glycerin would have contributed to the reduction of negative energy balance at the beginning of lactation. The lowest increase in aspartate transaminase (AST) and bilirubin level was observed in cows receiving glycerin. The study demonstrated that metabolic changes in Simmental breed cows in the periparturient period are dramatic, and an application of glucogenic precursors may improve metabolic efficiency.
