“…The plasma BHBA concentration reached was 1.7 ± 0.1 mmol/L, which was clearly above the considered concentration of 1.2 to 1.4 mmol/L referring to subclinical ketosis (Duffield et al, 2009;Ospina et al, 2010). The expected reduction of DMI in HyperB cows, as shown in cows with spontaneously elevated ketone body concentrations (Bareille et al, 2003;González et al, 2008), was not observed in our study. Subcutaneous injection of BHBA (10 mmol/kg of BW) in rats (Moor et al, 1976;Langhans et al, 1983), intraperitoneal BHBA infusion (15 mmol/kg 0.75 ) in pigmy goats (Rossi et al, 2000), and intracerebroventricular BHBA infusion (18mM/d) in dairy cows (Kuhla et al, 2011) decreased feed intake.…”

Elevation of ketone bodies in dairy cows frequently occurs in early lactation, usually concomitantly with a lack of energy and glucose. The objective of this study was to induce an elevated plasma β-hydroxybutyrate (BHBA) concentration over 48 h in mid-lactating dairy cows (i.e., during a period of positive energy balance and normal glucose plasma concentrations). Effects of BHBA infusion on feed intake, metabolism, and performance were investigated. Thirteen cows were randomly assigned to 1 of 2 infusion groups, including an intravenous infusion with Na-dl-β-OH-butyrate (1.7 mol/L) to achieve a plasma concentration of 1.5 to 2.0 mmol/L of BHBA (HyperB; n = 5), or an infusion of 0.9% saline solution (control; n = 8). Blood was sampled before and hourly during the 48 h of infusion. In the liver, mRNA transcripts related to gluconeogenesis (pyruvate carboxylase, glucose 6-phosphatase, mitochondrial phosphoenolpyruvate carboxykinase), phosphofructokinase, pyruvate dehydrogenase complex, and fatty acid synthesis (acetyl-coenzyme A carboxylase, fatty acid synthase) were measured by real-time PCR. Glyceraldehyde-3-phosphate dehydrogenase and ubiquitin were used as housekeeping genes. Changes (difference between before and after 48-h infusion) during the infusion period were evaluated by ANOVA with treatment as fixed effect, and area under the curve of variables was calculated on the second day of experiment. The plasma BHBA concentration in HyperB cows was 1.74 ± 0.02 mmol/L (mean ± SE) compared with 0.59 ± 0.02 mmol/L for control cows. The change in feed intake, milk yield, and energy corrected milk did not differ between the 2 experimental groups. Infusion of BHBA reduced the plasma glucose concentration (3.47 ± 0.11 mmol/L) in HyperB compared with control cows (4.11 ± 0.08 mmol/L). Plasma glucagon concentration in HyperB was lower than the control group. All other variables measured in plasma were not affected by treatment. In the liver, changes in mRNA abundance for the selected genes were similar between 2 groups. Results demonstrate that intravenous infusion of BHBA decreased plasma glucose concentration in dairy cows, but this decrease could not be explained by alterations in insulin concentrations or key enzymes related to gluconeogenesis. Declined glucose concentration is likely functionally related to decreased plasma glucagon concentration.

“…Costs associated with mastitis include lower production, discarded milk because of antibiotic therapy, labour, veterinary costs and treatments, and culling or death (Bartlett et al 1991). Several studies have found that clinical mastitis has a detrimental effect on milk yield (Bareille et al 2003;Bartlett et al 1991;Firat 1993;Gröhn et al 2004;Houben et al 1993;Rajala et al 1999;Shim et al 2004).…”

Kocak O.: Influence of Mastitis on Milk Yield in Holstein Cows. Acta Vet. Brno 2006, 75: 507-513.The objectives of the current study were to investigate the incidence of mastitis in a private dairy herd and the effect of the disease on the lactation milk yield (LMY), and on the daily average of the weekly milk yield (DMY). Only cows with no disease and cows with mastitis were included in the analyses. Mixed model procedures were used to analyse the DMY. Incidence of mastitis in the herd was 26.22%. The incidences of first, second and third parity groups were 19.94%, 33.74% and 40.74%, respectively. Daily milk losses because of mastitis varied between 0.76 kg/d and 4.56 kg/d. The total milk loss was 600.87 kg for cows that became mastitic in the first six weeks of lactation and was 503.86 kg for cows that became mastitic after the sixth week of lactation. The milk losses of cows that contracted mastitis after the sixth week of lactation, began three weeks before the diagnosis. The mastitic cows failed to reach their healthy levels of milk yield during the rest of the lactation. The results indicate that weekly lactation records are useful in early detection of mastitis.

“…As well, it is common for studies looking at milk production losses after a difficult calving to restrain their datasets to animals with full lactations or that have survived until a certain lactation stage. During the lactating period, dry matter intake was shown to decrease in cows that had experienced dystocia in the months postpartum (Bareille et al, 2003) compared to cows that calved normally, but this was not seen in the first two days postpartum ). This could relate to lower milk production observed in dystocial animals but also to the greater losses in weight and body condition score found in dystocial cows during their subsequent lactation (Berry et al, 2007).…”

Reproductive efficiency is a critical component of a successful dairy operation and acts as an important component of a profitable dairy farm, whereas reproductive inefficiency is one of the most costly problems facing the dairy industry today. Reproductive problems occur frequently in lactating dairy cows and can dramatically affect reproductive efficiency in a dairy herd. Some of the most common problems include twinning, dystocia, abortion, stillbirth, retained placenta and metritis. These are diverse disorders that are similar in that they all can result in impaired reproductive function. Deciding whether to breed, treat, or cull dairy cows exhibiting one or more of these reproductive problems is a challenge for both veterinarians and dairy producers. In addition, there is considerable controversy among dairy scientists and bovine practitioners regarding the economic impact of these problems in a dairy operation and the most effective management or therapeutic intervention for treating them. Because of this controversy, dairy managers should focus on prevention and control of risk factors associated with each problem rather than on prescriptive therapeutic interventions. Dairy producers should work closely with their herd veterinarian to develop such management strategies and discuss appropriate interventions when necessary (Fricke, 2001).Low fertility reduces the profit by decreasing the average milk production and the number of calves per cow per year. Poor reproductive performance is a major cause of involuntary culling and therefore reduces the AbstractThis review focuses on the potential effects of twinning, dystocia, stillbirth, abortion, retained placenta and metritis on the productive and reproductive performances in dairy cattle. These are diverse disorders that are similar in that they all can result in impaired performance of dairy cows. Reproductive problems occur frequently in lactating dairy cows and can dramatically affect reproductive efficiency in a dairy herd. Poor reproductive performance is a major cause of involuntary culling and therefore reduces the opportunity for voluntary culling and has a negative influence on the subsequent productivity of a dairy herd. Reproductive performance is influenced by the interactive effect of environment, management, health, and genetic factors. In addition, diseases mainly affect dairy cow productivity by decreasing reproductive efficiency, shortening the expected length of productive life and by lowering milk production. Deciding whether to breed, treat, or cull dairy cows showing one or more of these problems is a challenge for both veterinarians and dairy producers. In addition, there is considerable debate among dairy scientists and bovine practitioners regarding the economic impact of these problems in a dairy operation and the most effective management or therapeutic intervention for treating them. Because of this controversy, dairy managers should focus on prevention and control of risk factors associated with each problem rather than on prescr...
