“…Thus, omitting 1 or 2 milkings per week markedly increases fat and protein contents in the milk collected on the days after the milking omission in ewes (Casu and Labussière, 1972;Labussière et al, 1974a;Hervás et al, 2006), which dramatically modifies bulk milk composition. Similar results were reported previously in cows (Labussière and Coindet, 1968;Ayadi et al, 2003). Milk composition returns to normal values 2 or 3 d after the milking omission (Casu and Labussière, 1972;Labussière et al, 1974a;Ayadi et al, 2003).…”

“…Reported milk yield losses after omitting 1 milking per week vary according to sheep breed and study, ranging from nonsignificant values in Manchega (Huidobro, 1988), Poll Dorset (Knight and Gosling, 1995), and Assaf (Hervás et al, 2006) to 13% in Sarda (Casu and Labussière, 1972), 17% in Manchega (Gallego et al, 1984), and 26% in Préalpes du Sud (Labussière et al, 1974a). Sheep milk losses are greater than those reported after omitting 1 milking per week in dairy cows and dairy goats, which ranged from 3 to 8% (Labussière and Coindet, 1968;Le Mens, 1978;Ayadi et al, 2003). Omission of 1 milking per week increases milk fat (Labussière et al, 1974a;Huidobro, 1988) and milk protein contents throughout the lactation in sheep (Labussière et al, 1974a;Knight and Gosling, 1995).…”

The long- and the short-term effects of omitting 2 milkings weekly in early (wk 8 to 14) and mid lactation (wk 15 to 22) were investigated in an experiment conducted with a total of 58 dairy ewes (40 Manchega and 18 Lacaune). Ewes submitted to 2 milking omissions were milked twice daily from Monday to Friday (0800 and 1800 h), and once daily on Saturday and Sunday (1600 and 1400 h, respectively). Individual data were collected for milk yield (weekly), milk composition (biweekly), and somatic cell count (SCC; monthly). Omitting 2 milkings per week in early lactation tended to decrease milk yield in Manchega ewes (-15%), whereas no effects were observed in Lacaune ewes. Averaged milk composition was not modified by milking omissions in either breed. Milking omissions in late lactation did not affect milk yield and milk composition in either breed. The SCC were unaffected by milking omissions in both breeds and in both stages of lactation. A sample of 22 Manchega and 11 Lacaune ewes were used to evaluate the short-term (daily) effects of the 2 milking omissions per week on milk yield and composition, udder health, and tight junction permeability, both in early lactation (wk 12) and in mid lactation (wk 20). Milking omission decreased milk yield, milk fat, and milk lactose contents on the first omission day in both breeds, with losses being more noticeable in early lactation than in mid lactation. Milk protein content and SCC did not vary by effect of the weekend milking omissions. After restoring the twice-daily milking routine on Monday, milk yield showed a compensatory increase that was greater in the large-cisterned than in the small-cisterned ewes, which allowed milk yield to return to Friday values in both breeds. Milk fat content increased during Sunday and Monday, reestablishing Friday values thereafter in both breeds. Weekend milking omissions in early lactation caused tight junction leakiness in both breeds, but mammary epithelia adapted to extended milking intervals when applied successively, recovering their tight state after milking. In mid lactation, the mammary tight junction showed leakiness only in Manchega ewes. In conclusion, 2 milkings per week could be omitted with no negative effects on milk yield, milk composition, and milk SCC values in large-cisterned dairy ewes, as observed in Lacaune and large-cisterned Manchega ewes. Losses in milk yield could be reduced if milking omissions were done from mid lactation in small-cisterned ewes.

“…The practice of omitting 1 milking per week, generally applied during weekends, was developed and studied in France during the 1960s (Labussière and Coindet, 1968). Interest in this method was revived in France in 1996 so that dairy producers could manage a family farm without additional labor.…”

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

“…En France, dès les années 1960, des chercheurs ont envisagé de ne traire les vaches que 13 fois par semaine en supprimant la traite du dimanche soir (Labussière et Coindet 1968). Mais cette pratique n'a pas suscité l'intérêt des éleveurs, à une époque où ces derniers cherchaient à produire plus de lait plutôt qu'à disposer de temps libre.…”

Conséquences zootechniques de simplifications de pratiques : exemples de la distribution des aliments et de la traite des vaches

Les simplifications des pratiques telles que les modifications des modes et rythmes de distribution de l’alimentation et de la traite, influencent les performances zootechniques des ruminants. La distribution de l’alimentation hivernale par remorque mélangeuse qui broie partiellement les brins longs conduit à des niveaux d’ingestion d’autant plus élevés que les fourrages utilisés sont grossiers. La distribution séparée d’aliment concentrés de différentes natures à des agneaux à l’engrais ne modifie que peu les quantités et proportions moyennes ingérées d’un mélange et n’affecte pas la croissance. Mais la distribution d’ensilage une fois tous les deux jours ou trois fois par semaine, et l’alternance de la distribution des composants de la ration sur la semaine, sont des pratiques qui conduisent à une moindre utilisation nutritive des aliments de la ration. L’utilisation de ces techniques est possible mais limitée à des animaux modérément productifs. La monotraite des vaches réduit la production laitière de 10 à 30% avec un effet rémanent qui est d’autant plus important qu’elle est appliquée tôt dans la lactation et de façon prolongée. C’est une pratique qui entraîne parallèlement une diminution des quantités de fourrages ingérées. Ainsi l’animal peut mobiliser la plasticité du comportement d’ingestion et des processus digestifs et métaboliques pour s’adapter à des rythmes de distribution d’alimentation très variés sans modifier les lois de réponses aux apports alimentaires. Cette capacité d’adaptation est une caractéristique forte des ruminants sur lequel l’éleveur peut s’appuyer pour aménager son travail selon ses contraintes personnelles. En revanche, la plasticité de la lactation est moindre puisqu’une modification des conditions d’extraction du lait se traduit par des conséquences sur la lactation en cours, mais sans effet à l’échelle de la carrière de la vache. La modification des pratiques se raisonne donc toujours au regard des capacités d’adaptation des animaux qui nécessitent d'être mieux quantifiées par les travaux de recherches à venir.
