“…As part of the range of factors influencing mastitis, stress has been identified as a risk factor for high SCC (Wegner et al, 1976). In fact, higher frequency of kicking and stepping during milking during the first 3 days after mastitis detection was associated with the presence of mastitis (Medrano-Galarza et al, 2012), which supports the interaction terms in our models of milking behavior and SCC.…”

Keywords: dairy cows behavior type of milking parlor stepping kicking milk production a b s t r a c t We studied the relationship between behavior during milking with milking parlor management, measuring the occurrence of steps and kicks, and cow-related factors. We also investigated the link between stepping and kicking during milking and udder health. A total of 2,903 direct observations of milking behavior were collected in 44 dairy herds in the north of Portugal. The results showed great variability in the occurrence of stepping and kicking among herds during milking. Mixed linear and logistic regression models for factors associated with stepping and kicking were developed. Cows in tandem milking parlors took fewer steps (P < 0.003) than in herringbone ones, although in the tandem milking system, more kicking occurred than in parallel and herringbone systems. Milking room temperatures of more than 27 C led to a higher frequency of kicks among cows (P < 0.010). The practice of overmilking also produced a significantly greater frequency of cow stepping (P < 0.001). Primiparous cows stepped a third less frequently than did greater parity cows but showed a greater tendency to kick compared with the multiparous ones. Cows with somatic cell counts for more than 200,000 cells/mL at the time of the visit also showed a trend toward higher kicking frequency. The results suggest that animal welfare measures, like kicking and stepping, are suitable for epidemiologic studies. Significant interactions were observed when animals were affected by challenging health and welfare situations.

“…As observed earlier (D'Hour et al, 1994;Coulon and Garel, 1996) (D'Hour et al, 1994) and ewes (Animut and Chandler, 1996), glucose content was raised just after walking, in all likelihood due to increased muscular requirements (Pearson and Archibald, 1989 (Wegner et al, 1976). These results are, however, disputed (Paape et al, 1973 …”

Summary — Twenty-eight multiparous cows (14 Tarentaises and 14 Montbeliardes) in mid-lactation were used in a changeover design with two periods. Throughout the trial, animals received a second cut cocksfoot hay ad libitum, complemented with a fixed amount of concentrate adapted to the milk production of each animal. The first day of each of the two 8-day periods, one of the two groups (seven cows of each breed) was subjected to a single walking of 12.8 km. During the following 24 h, walking incurred a drop in the quantities of forage ingested (-1.1 kg dry matter/day, P < 0.01) and in milk yield, which was greater (P < 0.05) in the Montb6liarde (-3.3 kg/day) than in the Tarentaise (-1.7 kg/day) cows. At the same time, fat content increased similarly in both breeds (+6 g/kg, P < 0.01). ). Protein content increased only in the Montbeliarde cows (+1.) g/kg, P < 0.1). In both breeds, milk cell counts rose significantly after walking (+600 000 cells/mL, P < 0.01), but no occurrence of clinical mastitis was observed. Walking provoked a rise in body temperature (+0.5 °C, P < 0.01 ) and in nonesterified fatty acids (+1.18 mM/L, P < 0.01) and glucose (+0.08 g/L, P < 0.01) plasma contents.

“…It was indeed in herd 3, managed under the most adverse conditions in the third period, that the SCC increase (between periods 2 and 3) was the highest. Also, as evidenced in a case of stress due to high temperature [25], other factors related to the cows' exposure to weather conditions (wide temperature ranges, rain) or dietary factors (composition of pasture grass) may also have played a role without the possibility for us to verify it as a part of this study.…”

-The infection of udder by a pathogen and milk somatic cell count (SCC) of 220 quarters from 55 Abondance and Tarentaise cows coming from three Northern Alps herds were analysed three times: in June when cows use a valley pasture before turning to highland pasture and in July and September, respectively at the beginning and the end of highland pasture grazing period. During the three periods, 31% of the experimental quarters were free or infection, 61% were infected by a minor pathogen and 8% were infected by a major pathogen. In quarters infected by a major pathogen, SCC was constantly high (> 1 600 000 cells/ml in the three periods). SCC of uninfected quarters remained below 60 000 cells/ml in the three periods whereas SCC of quarters infected by a minor pathogen averaged 89 000 cells/ml in June and 512 000 cells/ml in September. For the latter, SCC was all the higher as the infection was older. Results are discussed according to the highland grazing conditions that may have had an impact on SCC. milk / somatic cell count / udder infection / highland pastureRésumé -Évolution au cours de l'alpage de la concentration en cellules somatiques du lait de vache en relation avec l'état infectieux des mamelles. Le statut infectieux et la concentration en cellules somatiques (CCS) du lait de 220 quartiers issus de 55 vaches de race Abondance et Tarentaise ont été analysés à 3 reprises -avant la montée en alpage lorsque les animaux utilisent des pâturages de vallée (juin), en début de saison d'alpage (juillet) et en fin de saison d'alpage (septembre) -dans 3 troupeaux des Alpes du Nord. Les animaux ont été choisis sur la base de leur concentration en cellules somatiques hivernale (toujours inférieure à 100 000 et 500 000 cellules/ml pour respectivement 75 % et 25 % des animaux).
