| 173 skulls of Swiss Brown dairy cows (horned=65, disbudded=165) were osteometrically sized. The greatest post-orbital width and the longitudinal height of the foreheads were recorded. The shape of the frontal bone was scaled into three categories: waveform, pointed, and straight. There was no significant influence of age on skull narrowness. More narrow skulls could be observed in dehorned cows than in horned cows. Dehorned cows had more pointed skull shapes, less waveform shapes, and less straight skulls. Whether these anatomic variances affect the wellbeing of cattle and how this alteration is exactly proceeding during growth should be examined in further studies. |

| Dental abnormalities in cows have seldomly been examined in research and veterinary check-up. This study estimated the prevalence of dental problems in cows. The skulls of 151 adult (> 4 years) dairy cows (Brown Swiss cattle n=81, Swiss Fleckvieh n=70) were categorized into three age groups (AK1: 4-6 / AK2: 7-9 / AK3: 10-16 years old) and examined for the existence of 11 dental cheek teeth abnormalities, based on well-known dental pathologies in horses. The four most prevalent dental abnormalities found were presence of abnormal spaces between 2 adjacent cheek teeth (Diastema), parodontosis, wavemouth, and food packing between cheek teeth. In 85% of all recorded skulls, 1 or more abnormalities were recorded. There were no differences in the occurrence... |
