Wide variety of timings and techniques has been used based on the housing, production, availability of requirements etc. This current study was done for a morphologic evaluation of the cow's digit in different trimming times. A dairy herd with 2200 milking cow, free stalls barns, average daily production of 36 liters per cow was selected. Forty cows were assigned to four groups based on hoof tr...
متن کاملEconomic evaluation of stall stocking density of lactating dairy cows.
An increase in stall stocking density (SSD), as measured by the number of lactating cows per stall in a freestall barn, reduces cow performance, such as milk yield and fertility, but may increase farm profitability. Our objectives were to calculate effects of varying SSD on profit per stall for a range of effects on cow performances and external farm factors and store results in regression meta...
متن کاملAdaptability of Dairy Cows to Robotic Milking: a Review
robotic milking systems (rMS) offer an innovative approach to improve productivity on dairy farms. rMS will influence the future growth of farms, the nature of husbandry employed and the quality of life on family farms. For farms using hired labour and located near industrial centres, RMS may contribute to the reduction of wage costs. As this technology is very expensive, and little is known re...
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...
