On-farm udder health monitoring

SummaryIn this article an on-farm monitoring approach on udder health is presented. Monitoring of udder health consists of regular collection and analysis of data and of the regular evaluation of management practices. The ultimate goal is to manage critical control points in udder health management, such as hygiene, body condition, teat ends and treatments, in such a way that results (udder health parameters) are always optimal. Mastitis, however, is a multifactorial disease, and in real life it is not possible to fully prevent all mastitis problems. Therefore udder health data are also monitored with the goal to pick up deviations before they lead to (clinical) problems. By quantifying udder health data and management, a farm is approached as a business, with much attention for efficiency, thought over processes, clear agreements and goals, and including evaluation of processes and results. The whole approach starts with setting SMART (Specific, Measurable, Acceptable, Realistic, Time-bound) goals, followed by an action plan to realize these goals.

AbstractMilk losses caused by intramammary infections (IMI) have a massive impact on farm profitability and sustainability. In this study, we analyzed milk losses from 4 553 treated IMI cases at 41 AMS dairy farms. Milk losses were estimated based on the difference between the expected and the true production. To estimate the unperturbed lactation curve, we applied an iterative procedure using the Wood model and a variance-dependent threshold on the milk yield residuals. We calculated milk losses both in a fixed window around the first treatment day of each IMI case and in the perturbations corresponding to this day, at cow level as well as at quarter level. In a fixed time window of day -5 to 30 around the first treatment, the absolute median milk losses per case were 101.5 kg, highly dependent on the parity and the lactation stage with absolute milk losses highest in multiparous cows and at peak lactation. Relative milk losses expressed in percentage were highest on the treatment day, and full recovery was often not reached within 30 days from treatment onset. In 62% of the cases, we found a perturbation in milk yield at cow level at the time of treatment. On average, perturbations started 8.7 days before the first treatment and median absolute milk losses increased to 128 kg milk per perturbation. Mastitis is not expected to have equal effects on the four quarters so this study additionally investigated losses in the individual udder quarters. We used a data-based method leveraging milk yield and electrical conductivity to project the presumably infected quarter and compared losses with the average of presumably non-infected quarters. Median absolute losses in a fixed 36-day window around treatment varied between 50.2 kg for front and 59.3 kg for hind infected quarters compared to respectively 24.7 and 26.3 kg for the median losses in the non-infected quarters. Also here, these losses depended on lactation stage and parity. Expressed proportionally to expected yield, the relative median milk losses in infected quarters on the treatment day were 20% higher in infected quarters with a higher variability and slower recovery. In 86% of the treated IMI cases, at least one perturbation was found at the quarter level. This analysis confirms the high impact of IMI on milk production, and the large variation between quarter losses illustrates the potential of quarter analysis for on-farm monitoring at farms with an automated milking system.HighlightsMilk losses were estimated for treated cases of intramammary infectionsMilk losses were highly variable across cases with a median of 101 kgWe found large differences between infected and non-infected quartersQuantification of milk losses can be the basis for better udder health management

Mastitis is an economically important disease of intensive buffalo dairy farming worldwide. Detection of subclinical mastitis (SCM) is important for its management and control. The purpose of this study was to estimate the prevalence of reproductive disorders, SCM and udder health management practices in the buffalo dairy farms of Bhola District, Bangladesh. Data on animal demographics, reproduction status, daily milk yield and status of California Mastitis Test (CMT) result were recorded. A total of 402 buffaloes were observed in two farms at Bhola district and among them 70 milking buffaloes were randomly selected for CMT. The overall prevalence of SCM in buffalo was 20.0%. Young age group of buffaloes was more susceptible for SCM and it was not significant difference. Parity and stage of lactation have no any effect on SCM. However, abortion case was more susceptible to SCM than other diseases but not any significant difference. During milking the milkers never use any antiseptic solution for washing the udder and never use any feed supply during milking. Among the isolated organisms Staphylococcus spp. and E. coli were found more frequent in the study area and gentamicin and ciprofloxaclin were most sensitive to the isolated organisms. From this study it was concluded that buffalo’s udder was very resistance to SCM infection and udder management practice was very poor. Common antibiotics were resistance to isolated organisms from SCM case. Gentamicin and ciprofloxacin were found more susceptible against all four isolated organisms.

Global concerns regarding bacterial antibiotic resistance demand prudent use of antibiotics in livestock production. Dairy production in the Nordic countries has a low consumption of antibiotics, while animal health, productivity and milk quality are at high levels. Here, we describe the basis of Nordic mastitis control and treatment strategies, as a model for production of high-quality milk with prudent use of antibiotics. We hope this will be beneficial for dairy producers and advisors in other countries and regions that consider limiting antibiotic use in cattle herds. In this perspectives paper we describe the dairy sector in the Nordic countries, and present regulatory aspects of antibiotic use, diagnostics and current guidelines for treatment of clinical mastitis as well as dry cow therapy. We also show summary statistics of udder health indicators in Denmark, Finland, Norway and Sweden, to illustrate the effects of the implemented udder health management practices.

Potential Alternative

Horticultural nurseries are heterogeneous and spatially complex agricultural systems, which present formidable challenges to management of diseases and pests. Moreover, nursery plants shipped interstate and internationally can serve as important vectors for pathogens and pests that threaten both agriculture and forestry. Current regulatory strategies to prevent this movement of pathogens and pests with nursery plants are based on visual inspections of plants just before shipping, a process that is costly and inadequate. Here we propose the application of a systems approach for horticultural nurseries modeled after the Hazard Analysis of Critical Control Points (HACCP) approach widely used in the food processing industry. We evaluated aspects of the systems approach to analyze contamination hazards by Phytophthora species and then implemented management practices targeting specific critical control points. The systems approach for analyzing and correcting unsafe practices offers a potential alternative strategy for preventing plant contamination that could be broadly applied to many pests and pathogens. One of the hallmarks of this approach is its flexibility, including the ability to improve and adapt the approaches as new technologies are developed or improved and to provide the grower with management options.
