Accuracy of oestrus detection in cows and its economic impact on Shiraz dairy farms
No report has been published on the economical losses associated with errors in oestrus detection in cows under Iranian intensive dairy management. The following study was carried out to determine the accuracy of oestrus detection by farmers using artificial insemination in Shiraz dairy farms. Milk samples were collected from 179 Holstein milking cows at the time of artificial insemination. Mil...
متن کاملA novel farm technology to quantify dairy cow cervix morphology: oestrus versus non-oestrus models
The objective was to quantify and compare cow cervical morphology on oestrus vs. non-oestrus daysusing a new farm technology. The cervical tissues were videotaped using a cervixscope involving newcamera equipment in four Holstein cows on multiple oestrus and non-oestrus days to score tissue morphology as altered by oestrus. The non-oestrous days were in diestrus phases. The videotaped records w...

متن کاملOestrus Detection in Dairy Cows Using Likelihood Ratio Tests
This paper addresses detection of oestrus in dairy cows using methods from statistical change detection. The activity of the cows was measured by a necklace attached sensor. Statistical properties of the activity measure were investigated. Using data sets from 17 cows, diurnal activity variations were identified for the ensemble and for the individual cows. A diurnal filter was adapted to remov...
متن کاملThe Rate of Growth of the Dairy Cow
Data are presented on the effect of age on milk secretion in the dairy cow. From the age when milk secretion usually begins (2 years) to the age when maximum body weight is reached (about 8 years) increase of milk secretion and increase of body weight with age follow the same exponential course, which is the course of a monomolecular reaction of chemistry. After this age, unlike body weight whi...
