چکیده

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 were processed in a computer installed with an image processing software. cervix central positioning, movements, mucosal secretions, and clarity in the captured images were scored visually, each on a 5-point basis. cervical regions were significantly more discrete, more mucosal, more central, and more stable on standing oestrus days than on non-oestrus days. during standing oestrus, the cervix was lucidly visible and rigidly positioned in the central end of vagina, whereas non-oestrus cervices were unstable and hardly separable from surrounding tissues. findings demonstrate the on-farm feasibility of the novel inexpensive cervixscope as a farm management tool for quantifying cervix morphology.

A novel biofarm technology to monitor and quantify oestrus cervix morphology in dairy cows

Increased cow productivity in the last few decades has depressed fertility and reproductive efficiency. Optimum uterus health and accurate true estrus detection have thus been greatly elusive on farm. The objective was to quantify cow cervix morphology during proestrus (PE), standing estrus (SE), diestrus (DE) and metestrus (ME) phases of the oestrus cycle using a novel biofarm technology. The ...

Brain monoamine levels in the cow during oestrus and metoestrus.

Norepinephrine, dopamine, and serotonin concentrations in the hypothalamus and stalk-median eminence were estimated in nine Hereford heifers at the onset of oestrus or 48 hr later. Significant differences in levels of monoamines at these stages of the oestrous cycle were not evident. Norepinephrine levels were similar in the hypothalamus and the stalk-median eminence, but dopamine and serotonin...

Oestrus 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...

Comparison of a camera - software system and typical farm management for detecting oestrus in dairy cattle at pasture.

AIM To compare the sensitivity, specificity, predictive values and accuracy of detection of oestrus using a novel oestrus detection strip (ODS) and a camera-software device (CSD) with typical farm management practices of visual observation and use of tail paint in dairy cattle at pasture. METHODS Dairy cows (n = 480) in a seasonal-calving herd managed at pasture under typical commercial condi...
