The purpose of this study was the long-term evaluation of a method of surgically repairing the abnormal condition of accessory teat and gland cistern complexes in dairy cattle. A prospective evaluation of three cows that had undergone the procedure was done. These cows were evaluated from four months to one year, postoperatively. A thorough history, physical examination, contrast radiography, a...
The milking unit can be detached at a milk flow rate of 400 g/min without having a negative effect on milk yield. Machine-on time is shortened and teat condition improved, and udder health does not seem to be affected. The threshold may be set even higher for cows milked more than twice daily. It is recommended that specific setting of switch points and delay times are evaluated for each farm. ...
Abstract Purpose Near-infrared spectroscopy (NIRS) sensors measure muscle oxygen saturation (SmO 2 ) as a performance factor in endurance athletes. The objective of this study is to delimit metabolic thresholds relative maximal steady state (MMSS) using SmO cyclists. Methods Forty-eight cyclists performed graded incremental test (GTX) (100 W-warm-up followed by 30 W min) until exhaustion. was m...
In one study, milk samples from individual mammary quarters (n = 4,148) in seven spring-calving dairy herds in Ireland were collected on two occasions during lactation to measure somatic cell counts (SCCs). All quarters were scored (0 to 4) for teat-end hyperkeratosis to establish a correlation between this score and SCC. In a second study, a herd of 56 autumn-calving Holstein/Friesian dairy co...
We evaluated the effectiveness of a 1.6% phenol-based teat dip using both a teat skin assay and natural exposure field trial. A teat skin assay was conducted to ascertain the concentration of phenol + phenate to be used in the field study. One percent and 0.5% iodine, and 0.5, 1.1, and 1.6% phenol + phenate were compared using Escherichia coli and Staphylococcus aureus. Logarithmic reductions f...
The experiment was carried out on lactating Holstein Friesian cows with the objectives of evaluating the effect of stage of age, pregnancy, lactation, parity and on yield, and components (fat, protein, solid not fat and lactose) and pH of milk. Milk samples were directly collected from the teat and immediately analysed using milk. The result showed that lactation stage and pregnancy significant...
In order to study the effects of sheep teat disorders on the protection of the mammary gland, we used a Mannheimia haemolytica isolate, which did not cause clinical mastitis when deposited into intact teats. In the first experiment, this was deposited into the duct of teats with orf (Group A, n=5) or papilloma (Group B, n=3). In the second, teats were chapped and then, the organism was deposite...
The objective was to describe the physicochemical changes during the early phase of subclinical mastitis and to associate them with pathological findings. A Mannheimia haemolytica strain was deposited into one teat duct of 25 ewes and the clinical, bacteriological, cytological, physicochemical (pH, milk composition), gross-pathological and histological findings were subsequently recorded. The o...
The main objectives of the experiment were: 1) to compare bacterial populations of mastitis-causing organisms on the teats of lactating dairy cattle housed on sand and sawdust bedding and, 2) to examine the relationship between bacterial counts present in the 2 bedding types with those on teat ends. Sixteen lactating Holstein cows were housed on either sand or sawdust-bedded free stalls using a...
Abstract We investigated the relationship between students' perceived stress and investment in learning tested role of future time perspective (FTP) as a moderator. expected that FTP would serve protective factor association learning. Perceived was gauged by assessing mathematics anxiety related to class, learning, tests, measuring with respect mathematics. To measure FTP, we focused on school ...
