“…The increased risk of CM in parity is consistent with the results of several authors (8,(12)(13)(14)(15). Steeneveld et al (16) reported that the incidence rate of CM in the first 10 days of lactation was higher in heifers than in multiparous cows. However, after 10 days of lactation, it was higher in multiparous cows than in heifers.…”

Herd management and data recordingData were collected in a commercial dairy farm in northern Morocco. The mean annual temperature is 18.7 °C, varying from 0 °C in February to 41 °C in August. The mean annual rainfall is 600 mm, mainly occurring from November to March.Data on Holstein cows were recorded between July 2008 and December 2012. Average age at calving was 47.6 months, ranging from 23 to 82 months, and average lactation number was 2.31, ranging from 1 to 4. During the study, the mean milk production per cow was 8066 kg per 305-day lactation.All cows were housed in free-stall barns. They were observed for estrus twice daily, in the morning and afternoon. Cows with estrus were inseminated within 1 h of detection. All lactating cows were fed the same diet, which was formulated to meet the nutrient requirements

“…In agreement with our results, another report showed for both heifers and multiparous cows, season of the year was significantly associated with the incidence of clinical mastitis (Steeneveld et al 2008). Olde Riekerink (2007) also showed that season was associated with bulk milk somatic cell count, individual cow somatic cell count, and incidence rate of clinical mastitis.…”

The aim of this study was to evaluate the effect of postpartum mastitis between first calving and subsequent conception on production and reproduction performance as well as culling of Holstein cows. A data set of 9,183 first lactation cows was used. Results showed that the first cumulative 100 days' milk production and the milk yield standardized to 305 days were affected by the interval from calving to first mastitis (P<0.05). Cows with one episode of mastitis produced more milk than those with repeated episodes of mastitis (P < 0.01). Increase in the number of mastitis episodes and also decrease in interval between first calving and mastitis increased services per conception (P<0.001). Mastitis episode and the interval between calving and first mastitis had no apparent impact on the calving to conception interval (P>0.05). Calving year, calving difficulty score, and cumulative first 60 days milk production had significant impacts on mastitis risk (P<0.05). The interval from calving to the first incidence of mastitis decreased over the period studied (P<0.001). Productive life tended to be decreased due to mastitis (P00.07). Survival analysis showed a significant difference between the lengths of productive life for cows with different intervals from calving to first mastitis (P<0.01). The results demonstrated that clinical mastitis between first calving and conception reduced production and reproduction performance with an increase in chance of culling.

“…Subclinical mastitis (SCLM) in heifers is an indicator for udder health and has been associated with production losses, higher probabilities of clinical mastitis, and culling (De Vliegher et al, 2005;Whist et al, 2007;Steeneveld et al, 2008). As a result, SCLM causes economic losses for the farmer (Huijps et al, 2009).…”

Heifer mastitis is a problem and risk factors may differ between heifers and older cows. The aim of this study was to estimate the heifer subclinical mastitis (HSCLM) incidence based on elevated somatic cell count (SCC) in the first 100 d in lactation and the associated risk factors in Dutch dairy herds. In 2008, 173 farmers filled in a questionnaire regarding housing and herd management factors potentially related to udder health. In addition, monthly milk production and SCC data from all cattle were provided by the Dutch Royal Cattle Syndicate (CRV, Arnhem, the Netherlands). Heifer subclinical mastitis incidence was calculated at the herd level as the number of heifer cases divided by the number of heifers at risk in the first 100 d in milk. Linear regression models were used for the analyses. On average, 25.5% [95% confidence interval (CI): 23.9 to 27.0%] of the heifers had subclinical mastitis. Heifers with a high SCC (>150,000 cells/mL) on the first test day after calving that returned to SCC levels below the cut-off continued to have a higher SCC throughout the study period compared with heifers with a low SCC (≤150,000 cells/mL) at the first test day after calving. Housing heifers together with lactating cows close to calving was protective from HSCLM incidence compared with separate housing (−4.5%; 95% CI: −8.7 to −0.2%). In addition, herds in which the farmer removed supernumerary teats of calves had a 7.0% (95% CI: 2.8 to 11.3%) lower HSCLM incidence and day and night grazing was also protective (−5.9%; 95% CI: −10.6 to −1.3%). Herds that were milked with an automatic milking system had, on average, a 6.9% (95% CI: 2.2 to 11.5%) higher HSCLM incidence and submitting milk samples for bacteriological culturing in the previous year was also associated with a higher HSCLM incidence (4.1%; 95% CI: 1.1 to 7.1%). Heifer subclinical mastitis is prevalent in all dairy herds, with a large variation in incidence. A high SCC in heifers at the first test day after calving appears to indicate a prolonged effect on udder health. Several management factors were found to be associated with HSCLM incidence that may help in reducing HSCLM.
