“…In our study, the increase in the content of serum albumin in milk was much less marked and systematic (table III) [5,31,32,33]. The lack of difference in the effect of omission of one milking-d-I between primiparous and multiparous cows confirms our preceding observations [22]. Nevertheless, Claesson et al…”

-The effect of temporary once-daily milking, starting right after calving, on milk production and nutritional status of 50 Holstein cows (15 primiparous) was studied. Primiparous cows were divided into two groups: a control group (Pc) continuously milked twice daily and an experimental group (P3) milked once a day for the first three weeks of lactation and then twice daily. Multiparous cows were divided into three groups: a control group (Mc) continuously milked twice daily, an experimental group milked once a day for the first three weeks of lactation and then twice daily (group M3), and another experimental group milked once a day for the first six weeks after calving and then twice daily (group M6). The trial ended when the cows were turned out to pasture. Cows milked once daily did not seem to suffer from discomfort. Once-daily milking decreased the milk yield by 2.7 kg.d-I (P < 0.10) in week I of lactation, by 8.4 kg.d-I (P < 0.01 ) in week 3 and by 14.5 kg.d-I (P < 0.01 ) in week 6. The effect of once-daily milking was not different between primiparous and multiparous cows. During the first week of twice-daily milking, the milk yield of experimental groups increased by 6.8 8 kg.d!' (a non significant difference between P3, M3 and M6 groups). From week 7 onwards, the milk yield of the P3 and M3 groups was lower than the milk yield of the Pc and Mc groups by 2.4 kg.d-I (P < 0.10), and the milk yield of the M6 group was lower than the milk yield of the Me group by 5.4 kg-d-I (P < 0.01 The protein content of milk was higher in experimental groups than in control groups by 2.4 g.kg-' during both experimental and post-experimental periods. Somatic cell counts in milk were not significantly different between the groups. Cows milked once a day lost less body condition and live weight in early lactation than control cows, and their energy balance was less negative or more positive (the difference was significant for the M6 group). (lot M6). L'essai s'est terminé à la fin de la période hivernale. La traite une fois par jour n'a pas semblé provoquer d'inconfort chez les vaches. Elle a diminué la production laitière de 2,7 kg-j-1 en 1 re semaine de lactation, de 8,4 kg-j-1 en 3' semaine, et de 14,5 kg!jw en 6 e semaine. Son effet n'a pas été différent entre les vaches primipares et multipares (p > 10 %). Dès la première semaine de traite deux fois-j-1 , la production laitière des vaches expérimentales a augmenté de

“…Greater intervals between milkings will reduce synthesis and secretion of milk and, thus, reduce milk yield. Nevertheless, a reevaluation in cows shows that this rhythm does not necessarily imply 3 strict intervals of 16 h between milkings, but may include varying intervals of 14, 18, and 16 h, for example (Rémond and Boit, 1997). By employing these 3 different intervals between milkings with an equivalent impact on milk production, milking outside of normal working hours can be avoided and could open a new future for this milking management system.…”

This paper aims to compare different adaptive responses of the mammary gland of cows, ewes, and goats submitted to extended milking intervals in different systems of management. Depending on the species, these extended milking intervals can be characterized by the following milk removal approaches; 3 milkings every 2 d, elimination of 1 milking per week (i.e., 13 vs. 14 milkings per week), and oncedaily milking with additional suckling (i.e., dual purpose system of suckling and milking) or without suckling (exclusive once-daily milking). All the high-yielding animals and breeds adapted without problems to being submitted to intervals between milking less than 20 to 21 h. Under these conditions, all ruminant species demonstrated only low and transitory variations in milk production and quality. Thus, management systems using such an interval are good tools for the dairy producer who wants to save time without important adverse economic impact. When animals have good mammary gland health, these management systems can be applied without preliminary adaptation. However, goats and some breeds of dairy ewes seem to adapt

“…With regards to milk composition, intervals longer than 16 hours may lead to variations in fat content in dairy cows ( [80], see review [104]). On the contrary, in mid-and late-lactation dairy ewes, a 16 hour milking interval has no effect on milk composition as compared to ewes milked every 12 hours [66].…”

-This review describes the effects of milking (routine and management) on milk yield and milk quality on dairy ruminants and examines the physiological effects of milking on the synthesis and secretion of milk. During milking, differences in the composition of milk as a result of milk ejection reflex are observed: the cisternal milk, immediately available, contains little fat, then milk ejection provokes active transport of high-fat content alveolar milk, into the cisternal compartment. Milking frequency has the capacity to affect milk production too. So, an increase in milking frequency augments milk yield whereas a decrease in milking frequency decreases milk production, with effects on milk composition. The milk ejection reflex is mediated by oxytocin, which induces myoepithelial cell contraction. Nevertheless, other actions of oxytocin may exist, such as a direct effect on proliferation and differentiation of myoepithelial cells and on secretory processes in the mammary epithelial cells. milking / milk ejection / oxytocin / physiological effects / milk quantity and quality Résumé -Ocytocine et vidange mammaire : deux facteurs de variation essentiels de la quantité et la qualité du lait pendant la traite et entre les traites. Cette revue bibliographique pré-sente les effets de la traite (technique et conduite) sur la production quantitative et qualitative de lait, puis précise les mécanismes d'action des effets physiologiques de la traite sur la synthèse et la sécrétion des composants du lait. Au cours d'une traite, la composition du lait évolue, grâce au réflexe d'éjection du lait qui provoque le transfert du lait alvéolaire, riche en matières grasses, vers la citerne. Ainsi, le lait de début de traite est pauvre en matière grasse, tandis que le lait de fin de traite est riche en matière grasse. Les rythmes de traite ont aussi un impact sur la production laitière. Ainsi, l'accroissement de la fréquence de traite augmente la production laitière alors que la réduction du nombre de traite la diminue, avec des répercussions en terme de qualité du lait. L'hormone responsable de l'éjection du lait, l'ocytocine, exerce son rôle de vidange mammaire par déclenchement de la Reprod. Nutr. Dev. 42 (2002) 173-186 173
