Comparison of weigh-suckle-weigh and machine milking for measuring ewe milk production.
Thirteen crossbred ewes were used to compare weigh-suckle-weigh (WSW) and machine milking (MM) methods for determining milk production of ewes that were rearing single or twin lambs. At parturition, ewes were 13 mo of age and produced six single lambs and seven pairs of twin lambs. Milk production estimates were initiated on d 6 of lactation and a 3-d rotation of the two techniques was implemen...
متن کاملPhysiology of Lactation and Machine Milking
The main purpose of this article is to describe interaction between physiology of lactation and milking machine. This is important in order to avoid bad influ ences (such as: high somatic cell count (SCC), mastitis, etc.). The paper is divided into two parts: The anatomy part describes udder characteristics needed for healthy udder and high milk yield. The milking machine part describes milkin...
متن کاملAdvances in machine milking: The influence of milking on teat condition and mastitis risk
A simple method developed and validated by Dr. Pamela Ruegg (Schreiner and Ruegg, 2003) for scoring udder hygiene has proved an invaluable tool to monitor the effect of the cow environment on udder cleanliness. Udder hygiene scores showed a significant association between poor udder hygiene and increasing individual cow linear score and the prevalence of intramammary infection with an environme...
متن کاملMilking-time Test – Methodology and Assessment of Vacuum Recordings during Machine Milking of Dairy Cows
The aim of the study was to improve the basic understanding and the methodology of routine milking-time testing by determining the required sampling frequency and number of cows and milkings needed to be measured in order to yield representative results. Milking-time tests represent the most direct method to validate the system vacuum of a milking machine, both the aptitude of vacuum production...
متن کاملComparative Study on Milking Ability of Sahiwal Cows and Murrah Buffaloes under Hand and Machine Milking
Present study was undertaken to compare the effect of two different milking methods (hand vs. machine milking) on milking ability in Murrah buffaloes and Sahiwal cows. 30 lactating Sahiwal cows and 30 lactating Murrah Buffaloes were selected and divided into four equal groups having 15 animals each. 15 animals of each species were subjected to machine milking and 15 animals of each species were...
