“…The day to day milking order appeared to be very weakly but significantly consistent during the observation period, indicating that cows tended to follow a repeatable order when walking into the milking parlour. This consistency of milking order has also been found in other studies in dairy cattle (Grasso et al, 2007), buffalo cows (Polikarpus et al, 2014) and sheep (Villagrá et al, 2007). Polikarpus et al (2015) found that milking order in dairy cows was consistent within and across days, but seemed to be more variable within milking sessions.…”

“…Polikarpus et al (2015) found that milking order in dairy cows was consistent within and across days, but seemed to be more variable within milking sessions. The milking parlour used in this study had a right and a left side and, in addition to consistency in milking order, cows have shown a side preference, as described by Grasso et al (2007).…”

“…It is a generally held perception that cows follow a specific milking order (Dickson et al, 1967;Rathore, 1982;Grasso et al, 2007). Several factors can influence the milking order, with sickness being one influence.…”

Animal health issues are a problem on many dairy farms, and much is already known about clinical treatments and the behaviour of sick animals. Animal health issues can influence behaviour seen around the milking parlour, but less is known about the relationship between the number of previous medical treatments and the queuing to be milked, the 'milking order'. Information was collected on five afternoon milking sessions, the individual cows' age and the medical treatment history of each cow in a group of 100 cows. The question addressed was whether the age and the medical treatment history of each cow in the herd affected its milking order. In addition, milking order was tested day to day, and was found to be consistent. A significant positive correlation was found between medical treatment history and milking order rank, meaning that cows with a higher medical treatment history tended to enter the milking parlour later than cows with a lower medical treatment history. In contrast with this finding, it was found that older cows were more likely to enter the milking parlour early when compared to younger animals, a finding which is supported by previous studies. These somewhat contradictory effects of (a) age and (b) medical treatment history on milking order suggest that health disorders may have long-term measurable effects on the position of a cow in the milking order, even when the effect of age on milking order is accounted for.Keywords: treatment history, milking order, dairy, disease, age ImplicationsWe found effects of both age and medical treatment history on milking order, and these suggest that health disorders may have long-term measurable effects on the position of a cow in the milking order, even when the effect of age on milking order is accounted for. These findings could lead to a better understanding of factors influential on the milking order in dairy cows, and therefore might result in better management around the milking procedure with an understanding of the potential for medical treatments to influence behaviour around milking.

“…No relation between milk yield and entry order into milking parlour was observed in Manchega sheep (Villagra et al 2007). However, higher milk yield in animals entering the parlour early was observed in goats and cows (Margetinova Grasso et al 2007). Animals in FG had higher peak flow rate and needed shorter time to start milk flow (latency time) than LG ewes (1.04 vs 0.77 l/min and 14 vs 20 s, respectively (P < 0.01)).…”

Mačuhová L., Tančin V., Mačuhová J., Uhrinčať M., Hasoňová L., Margetínová J. (2017): Effect of ewes entry order into milking parlour on milkability and milk composition. Czech J. Anim. Sci., 62, 392-402.The aim of the present investigation was to evaluate how the order in which the ewes in a milking group enter the milking parlour affects their milkability and milk composition. Therefore, the order of entry into the milking parlour was evaluated in ewes of one flock (n = 353) during six evening milkings. In all, the sheep were milked in 15 milking groups. The sheep entering the milking parlour in the first milking group achieved 15 points and the sheep of each next milking group one point less, i.e. the sheep of the last group achieved 1 point. In the analysis, only the ewes with the highest and the lowest average number of points were included and assigned to the first (FG, n = 19) and the last group (LG, n = 29), respectively. After the last milking, the individual milk samples were collected from the jar to analyze the composition and somatic cell count. Machine milk yield in 30 s (0.15 ± 0.09 and 0.11 ± 0.05 l) and 60 s (0.26 ± 0.16 and 0.19 ± 0.10 l), peak flow rate (1.04 ± 0.39 and 0.77 ± 0.29 l/min), and latency time (14 ± 3 and 20 ± 13 s) significantly differed (P < 0.05) between FG and LG, respectively. Total milk yield (0.41 ± 0.17 and 0.35 ± 0.14 l) and machine milk yield (0.27 ± 0.15 and 0.22 ± 0.10 l) tended to be higher (P = 0.05 and P = 0.09) in FG than in LG, respectively. No significant differences were observed in milk composition between FG and LG. It seems that ewes which enter the milking parlour in early milking groups have better parameters of milkability than those milked in later groups.
