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 کاملUdder Morphological Traits and Milk Yield of Chilota and Suffolk down Sheep Breeds
Morphological traits of the whole udder (circumference, width, height, and length), teats (angle, length and width), udder cistern (teat opening and cistern height), and milk yield were measured over one lactation in a total of 18 ewes (nine Chilota and nine Suffolk Down sheep) belonging to the same experimental flock (Centro Experimental INIA Butalcura, Chiloé, Chile). Analysis of variance sho...
متن کاملThe comparison between ultrasonography and 99mTc-DMSA renal scan in estimation of kidney size
Introduction: Renal length measurement is an important diagnostic clue in several urinary tract abnormalities. Although ultra sonography is the most frequent used modality for renal size estimation, renal diameter assessment by 99mTc-DMSA scintigraphy is of great value. By now, pointing to the renal size in the 99mTc-DMSA scintigraphy report has not been recommended by gui...
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 کاملGenetics of udder health in dairy ruminants
Udder health troubles in dairy ruminants mainly include intra mammary infections, or mastitis, caused by a pathogen that enter the gland through the teat canal and develop in the gland cistern. Mastitis is a multifactorial disease; it’s origin, severity and outcome are highly variable and depend on environment, a wide variety of pathogens (mostly bacteria) and host. In dairy cattle, mastitis is...
