“…A possible explanation for the decline in milk yield is that it might be a result of early involution events that are related with an increase in apoptosis and a decrease in proliferation of secretory cells. These results are in agreement with previous studies that reported a decrease of milk yield after 24-h of re-milking and return to the pre-treatment milk levels within a period ranged from 30 h to a week after 40 h, 2, 4 and 7 d milk stasis in dairy cows (Farr et al 1998;Dalley & Davis, 2006;Stelwagen et al 2008;Singh et al 2015). In goats, a decrease of milk yield was reported after 36 h of non-milking (Stelwagen et al 1994b;Ben Chedly et al 2009).…”

The majority of the work today regarding the effects of extended milking intervals has focused on dairy cattle and only to a limited extent on dairy goats and sheep. The aim of this study was to investigate the effect of different non-milking intervals on milk yield and composition, mammary physiology and welfare indices in dairy ewes. Thirty-six multiparous ewes in late lactation were allocated to one of four groups of nine and subjected to 24, 48 or 72 h of non-milking or normal milking interval (12 h) (group A, B, C and D, respectively). Data showed that there were no significant differences in milk yield among the experimental groups during the third day after re-milking. Furthermore, no significant differences in milk lactose, protein and fat concentration among the experimental groups were observed after 7, 14 and 21 d of re-milking, respectively. Non-milking for 72 h resulted in a temporary increase of sodium concentration, Na + /K + ratio and enzymatic activities of plasmin (PL), plasminogen (PG) and plasminogen activator (PA) in milk. However, these parameters had similar values among the experimental groups on day 5 after re-milking. The concentration of lactose in blood was also significantly increased as a result of the 72 h non-milking interval and returned to its initial levels the second day after re-milking. These data, taken together, suggest that early involution events that occurred as an effect of non-milking were fully reversible within a short period of time. Finally, no significant signs of welfare impairment were observed in ewes due to extended milking intervals. In conclusion, non-milking up to 72 h had no negative effects on milk yield and composition, mammary physiology and welfare parameters in dairy ewes.

“…L'intervalle de traite joue également un rôle sur la production journalière. Différentes sources indiquent que la production de lait par vache ne peut présenter une diminution que si la limite physiologique d'un intervalle acceptable de 16 à 18 heures est atteinte (De Bie et al, 2000 ;Stelwagen et al, 2008). Dans le cas d'une traite journalière, la diminution de la production est due à l'augmentation de la pression mammaire en raison des intervalles de traites prolongées entrainant la perte de la fonction de sécrétion des cellules épithéliales mammaires (Delamaire et Guinard-Flament, 2006).…”

RESUME L'amélioration de la productivité laitière par le métissage a eu des résultats limités dans les pays à faible rendement car les métisses résistent peu aux dures conditions climatiques. Des alternatives ont été envisagées sur la vache Zébu la mieux adaptée aux conditions du Sahel. L'objectif de cette étude était de tester l'effet de la fréquence de traite sur la productivité de la vache Zébu Peulh. Vingt-quatre (24) vaches Zébu Peulh, primipares et multipares situées entre le premier et le quatrième mois de lactation ont été réparties dans un dispositif expérimental en Carré Latin afin de tester l'effet de la fréquence de traite sur la production du lait. Les vaches étaient réparties en trois lots de huit (8) La spectroscopie a été utilisée pour déterminer la composition du lait (Farm Milk Analyzer, Miris AB, Suède). Les données ont été analysées au moyen du logiciel R et le test de Student a été utilisé pour faire les comparaisons au seuil de probabilité P < 0,05. Les résultats montrent que quand on comparait la production d'une traite à celle de deux traites, on obtenait une augmentation significative de la production de 60,6% par jour soit +0,71 litre. Il en était de même en comparant la production de lait d'une traite à celle de trois traites. En plus, quand on comparait la production de lait de deux traites à celle de trois traites, l'augmentation était de 84,9% par jour soit +1,47 litres. L'augmentation de la fréquence de traite à deux et trois traites journalière améliore quantitativement la productivité de la vache sans variations notables de la composition du lait. © 2016 International Formulae Group.

Strategies have been developed to increase local Zebu cattle productivity more adapted and well spread in the Sahel Zone of Africa. The aim of the study was to test effect of milking frequency on Zebu cattle production. Twenty four (24) primiparous and multiparous Zebu cattle between first and fourth month of lactation were allocated in Latin Square experimental design in order to test effect of milking frequency on milk production. All cows were assigned in group of eight corresponding to once daily milking (1X), twice daily milking (2X) and three times daily milking (3X). Milking interval was 24 hours, 11-13 hours and 05-6-13 hours for 1X, 2X and 3X respectively. Milk volume was measured and milk samples were collected each week from july to december 2015. Milk samples were run using infra-red spectroscopy (Farm Milk Analyzer, Miris AB, Sweden). All data were M. SISSAO et al. / Int. J. Biol. Chem.

“…The consequences of short (,8 h) or long (.16 h) milking intervals on milk secretion have essentially been determined in analytical experiments using specific designs: intervals tested once (Stelwagen et al, 2008), or applied several times consecutively, which modifies the daily milking frequency (Schmidt, 1960;Ayadi et al, 2004;Delamaire and Guinard-Flament, 2006); complete milk removal from the udder through oxytocin administration before the experimental interval in order to empty the mammary reservoirs (Schmidt, 1960;Wheelock et al, 1966); a standard 12 h milking interval preceding all the experimental intervals (Wheelock et al, 1966;Fernando and Spahr, 1983), and generally a short duration of experimentation (1 day to a few days), though not always (60 days for Villiers de and Smith (1976)). These experimental conditions differ from those met in practice and cannot provide reliable information on the effect of widely contrasting milking intervals on milk production in commercial TDM herds.…”

The time constraints of the classic twice-daily milking routine are less easily endured by individual dairy farmers, because of their impact on quality of life. Our aim was to evaluate milk production responses by dairy cows milked twice daily at contrasting intervals. In experiments 1 (20 cows) and 2 (28 cows), four milking regimes were compared during a 3-week period beginning after the peak of lactation. Three groups of five cows were milked twice daily (TDM) with milking intervals of 11 : 13, 7 : 17 and 3 : 21 h in experiment 1, and three groups of seven cows at 11 : 13, 5 : 19 and 2.5 : 21.5 h in experiment 2. One group (five and seven cows respectively) was milked once daily (ODM) in each experiment. In experiment 3 (three groups, 12 cows per group), one group was milked at 10 : 14 h and one at 5 : 19 h, and the third group once daily. Milking treatments began during the second week of lactation and continued for an average of 23 weeks. In experiments 1 and 2, daily milk yields were reduced by 4.1%, 11.5% and 28%, for the 5 : 19, 3 : 21 and ODM milking treatments compared with the 11 : 13 h interval. In experiment 3, the decrease in daily milk yields for 5 : 19 h and ODM was 10% and 40% compared with the 10 : 14 h time interval. In the average daily milk, fat and protein contents and somatic cell counts were not different between the TDM groups, and the ODM group had (or tended to have) a higher fat and protein content. For a given milking, milk fat content decreased from about 60 to 32 g/kg as the preceding milking interval increased from 2.5 to 3 h up to 12 h. It then levelled out and even increased, mainly after 18 to 20 h. Somatic cell count showed a similar trend, and protein content did not change steadily. Dry matter intake, body weight and body condition score were not affected by contrasting milking intervals. After resumption of TDM with conventional intervals, productions of milk, fat and protein no longer differed between the TDM groups. Milk yield of previously ODM cows remained lower by 2 kg/day ( P 5 0.15) in experiments 1 and 2, and by 7 kg/day ( P , 0.05) in experiment 3. These results suggest that TDM at contrasting intervals up to 5 : 19 h is feasible as it decreases milk yield only moderately, especially if implemented from peak of lactation.
