Preliminary Observations on Milk Flow and Udder Morphology Traits of East Friesian Crossbred Dairy Ewes
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 ...
متن کاملPreliminary Results: Effects of Udder Morphology on Commercial Milk Production of East Friesian Crossbred Ewes
Udder and teat morphology measurements were taken at approximately 7.5 hr after the a.m. milking for 131 East Friesian (EF) crossbred ewes at an average of 71 d in lactation. Additionally, milking time was recorded for each ewe during two evening and morning milkings. Average daily milk production, milking time, percentage of milk fat, percentage of milk protein, and somatic cell count were 2 L...
متن کاملEffects of udder traits on the milk yield of sheep
In order to determine the possible effects of udder traits on milk yield and milk composition a serial of experiments were carried out on five different sheep farms, between 1998-2000. Ten breeds and genotypes were included in these experiments: Merino, (Merino x Pleven Blackhead) F1, Pleven F1 x Black East Friesian, Lacaune, (Merino x Lacaune) F1, British Milksheep, (Merino x British Milksheep...
متن کاملRelationship between Peak Milk Yield and Udder Parameters of Dehong Crossbred Dairy Buffaloes
To determine the relationship between udder traits and peak milk yield, udder parameters of 203 Dehong crossbred dairy buffaloes were measured. The average peak milk yield (kg/day) of buffaloes was 9.60 ± 2.73, with average udder dimensions of 16.51 ± 10.05, 8.07 ± 3.26, 8.68 ± 3.92, 50.74 ± 8.82, 11.38 ± 3.08, 7.18 ± 2.18 and 7.73 ± 2.15 cm for udder depth, rear udder width, rear udder height,...
متن کاملUdder Size in Relation to Milk Secretion
The results herein presented furnish exact critical evidence for the conclusion that the most of the milk is present as such in the udder of dairy cattle at the time of milking. The amount of milk which may be secreted during milking cannot, on the basis of these results, be over 20 per cent of the milk yield of the cow. The results show clearly that the size of the udder measures closely the a...
