“…These results support previous findings of the substantial cost associated with mastitis (Kossaibati and Esslemont, 1997;Seegers et al, 2003;Hagnestam-Nielsen and Østergaard, 2009) and the hampering effects mastitis has on the economic outcome of the farm (Hansson, 2007).…”

“…Mastitis is a disease with severe economic consequences for farmers because of its high incidence and the extensive costs associated with the disease: it is considered the most costly disease in dairy production (Degraves and Fetrow, 1993;Kossaibati and Esslemont, 1997;Seegers et al, 2003). Several European studies report cost estimates per case of clinical mastitis in the range of h210 to 428 (Østergaard et al, 2005;Huijps et al, 2008;Hagnestam-Nielsen and Østergaard, 2009).…”

The aim of this paper was to explore if, and in that case how, various preventive measures against mastitis influenced the whole-farm economic outcome, measured as technical efficiency, of a sample of specialised dairy farms in Sweden. In particular, the paper aimed at analysing whether a change to preventive measures applied by fully efficient farms would be a way for inefficient farms to become fully efficient. First, technical efficiency was assessed for each farm in the sample based on farm-level accounting data and the data envelopment analysis. In a second step, the effects of preventive measures against mastitis (collected through a mail questionnaire) on technical efficiency were assessed with logistic regression. Keeping cows in a loose-housing barn, stimulating udders manually during milking, and having cows standing on clean bedding during milking were found to significantly increase the probability of a farm being fully efficient. Once the farmer considers the somatic cell count (SCC) to be too high, undertaking measures such as contacting a veterinarian, checking overall hygiene routines, and culling cows with high SCC were found to significantly increase the probability of a farm being fully efficient. Thus, these measures may be plausible targets for advisory services aimed at assisting farmers to become fully efficient, especially if they are confirmed in future studies. Several common preventive measures against mastitis, that is, choice of bedding material, frequency of cleaning stalls, pre-milking, post-milking teat disinfection, applying a milking order based on the SCC of cows, and milking high-SCC cows with a separate cluster, were found to have no statistically significant effect on farm economic outcome. However, these measures may still be valuable for non-economic goals, such as increased animal welfare, and the results imply that they can be implemented without negative impact on the economic performance of the farm.

“…In most previous work on the economic consequences of CM, yield loss has been described in the same manner irrespective of when, in lactation, CM occurred: Kossaibati and Esslemont (1997) and Yalcin (2000) used a constant yield loss, whereas Østergaard et al (2005) used a spline function to illustrate the yield loss. Studies have, however, indicated that the magnitude of yield loss depends on the lactation stage in which the cow develops CM (Lucey and Rowlands, 1984;Rajala-Schultz et al, 1999;Hagnestam et al, 2007).…”

Economic impact of clinical mastitis in a dairy herd assessed by stochastic simulation using different methods to model yield losses

The main aim of the present study was to examine the economic consequences of a reduction in the incidence of clinical mastitis (CM) at herd level under current Swedish farming conditions. A second objective was to ask whether the estimated cost of CM alters depending upon whether the model reflects the fact that in different stages of lactation, CM gives rise to different yield-loss patterns or postulates just one type of yield-loss pattern irrespective of when, during lactation, CM occurs. A dynamic and stochastic simulation model, SimHerd, was used to study the effects of CM in a herd with 150 cows (9000 kg of energy-corrected milk per cow-year). Four herd types, defined by production level and reproductive performance, were modelled to investigate possible interactions between herd type and response to a reduction in the risk of CM. Technical and economic results, given the initial incidence of CM (25.6 per 100 cow-years), were studied together with the consequences of reducing the initial risk of CM by 50% and 90% throughout lactation and the consequences of reducing the initial risk by 50% and 90% before peak yield. A conventional way of modelling yield losses -i.e. one employing a single yield-loss pattern irrespective of when, during the lactation period, the cow develops CM -was compared with a new modelling strategy in which CM was assumed to affect production differently depending on its lactational timing. The effect of the choice of reference level when estimating yield losses was investigated by comparing the results obtained using the potential yield of mastitic cows, had they not developed CM, with those obtained using the yield of non-mastitic cows. The yearly maximum avoidable cost of CM at herd level was estimated at h14 504, corresponding to 6.9% of the net return given the initial incidence of CM. Expressed per cow-year, the maximum avoidable cost was h97. The cost per case of CM was estimated at h428. Herd types all responded in a similar manner to the reduced relative risk of CM. There were no major differences in the results obtained using the new and the conventional modelling strategy, with the exception of the cost per case of CM. Similarities between the results obtained using the two methods were particularly evident when the mastitic cows' own yield level, had they not developed CM, was used as the reference for production in healthy cows when yield losses were estimated. It was concluded that the conventional way of modelling yield losses is adequate and should, for the foreseeable future, be used in decision support systems.

“…Mastitis is an inflammatory disease which causes significant economic losses to the dairy industry (Geary et al, 2012;Kossaibati and Esslemont, 2000). The efficiency of the host defense system plays a major role in the ability to deal with mastitis-causing pathogens, and thus ultimately in determining the severity of infection (Burvenich et al, 2003;Rainard and Riollet, 2006).…”
