Milk yield, milk flow, and udder morphology traits were measured in 72 East Friesian crossbred multiparous ewes to estimate the variation in milk flow patterns present in this research flock, and to asses the repeatability of these measurements and their relationships with other lactation traits. A special milk flow apparatus designed for dairy ewes was used on two consecutive morning milkings ...

Both the new ASAE S518 standard (2) and the revised draft international standard DIS/ISO 5707 (3) incorporate performance standards for vacuum stability in milking systems. New NMC procedures for system evaluation include dynamic tests for vacuum stability to demonstrate the adequacy of new or existing milking systems (7) . Such dynamic (i.e. "milking-time") tests require the use of test instru...

milk samples from high and low milk producer holstein cows, were obtained during the morning and afternoon milking over a one week period. overall, 1064 samples were tested within 14 times sampling in urmia, iran. milk macro-mineral concentrations in the morning milking and in low producers were greater than in the afternoon and in high producers. the highest and lowest concentrations were obse...

Milk yield and plasma oxytocin (OT), prolactin (PRL), and cortisol (CORT) during suckling and machine milking were measured in multiparous ewes subjected to a mixed management system of 3 sucklings and two daily milkings. Peak hormones were significantly increased and were similar during suckling and milking for PRL (181 vs. 163.3 ng x mL(-1)) and CORT (12.5 vs. 11.5 ng x mL(-1)). During the pe...

The effect of milking stimulus on the plasma prolactin concentration of lactating cows and goats was investigated by a radioimmunologic procedure. Plasma prolactin level in seven cows was increased abruptly 1 to 2mins. after the start of milking. On the other hand, the level of the hormone was increased shortly before the onset of milking in two cows at early lactation stage. In the goats at mi...

Dairy horse breeding in Ukraine is not a traditional branch of animal husbandry, although its products most closely correspond to the physiology human digestion and are especially indispensable children's nutrition, since chemical composition mares' milk close that women. To obtain mare's milk, it necessary take into account technological features keeping, feeding animals obtaining specific par...

Dairy cows often have to choose which of two sides to enter in the milking parlour. Some cows are very consistent in this choice, and it is common to assume that when these cows are more disturbed are being milked in their non-preferred side. Such disturbance might involve significantly poor welfare. In order to assess this assumption, we decided to study the behaviour and milk yield of dairy c...

The objective of the study was to explore effect breed on composition and coagulation properties (rennet time (min), curd firming rate firmness (mm)) milk from cows milked once a day or twice in morning afternoon, using Formagraph. Thirty (11 Holstein-Friesian, 8 Holstein-Friesian × Jersey cross, 11 Jersey) once-a-day milking herd thirty (16 10 4 twice-a-day were sampled late lactation. analyse...

Following colostrum management training, a randomized field trial was conducted on a California dairy to determine the effect of supplementing pooled colostrum with either colostrum-derived replacer (CDR) or second-milking colostrum (transition milk) on failure of passive transfer (FPT) and preweaning morbidity risks. A total of 166 calves were randomly assigned to 4L first-milking pooled colos...
