Abstract
This study aimed to investigate environmental mastitis causing bacteria counts in the teat end, somatic cell counts (SCC) of milk samples, cleanliness scores and behavior of cows kept on concrete and rubber mat floorings. For this purpose, 19 Holstein-Friesian dairy cows were allocated into concrete and rubber mat groups. Swab samples were taken from the teat ends to determine the bacterial counts causing environmental mastitis. Milk samples were collected from a composite of all four quarters to determine the SCC. Instantaneous sampling method was utilized to observe the behavioral activities of cows. Cows were visually evaluated to determine the udder cleanliness score. Independent samples t-test was utilized in the statistical analysis of the obtained data. Coliform (P<0.05), Escherichia coli, and Klebsiella spp. (P<0.01) counts of the swab samples taken from the cows housed on concrete flooring were significantly higher than rubber mat group. However, no statistically significant differences were found between groups in terms of total bacteria, Streptococcus spp., and Enterobacteriaceae counts. The SCC on samples taken from cows kept on concrete surface were significantly higher (P<0,05) than that of animals housed on rubber mat. Furthermore, cows in the rubber mat group were determined to be significantly cleaner (P<0.05) than those in concrete group. It was also determined that the cows housed on rubber mat spent significantly longer time for lying behavior (P<0.05), which is a significant indicator of animal comfort. The time spent for standing without eating was considerably higher (P<0.01) in concrete group. In addition, the times spent for eating was significantly lower (P<0.01) in the concrete group. It was concluded that, using rubber mat instead of concrete for flooring in tie-stall barns decreases the contamination of environmental mastitis pathogens, increases milk quality and cow cleanliness score as well as animal comfort and welfare.
本研究旨在调查乳头末端引起环境乳腺炎的细菌数量、牛奶样本的体细胞数（SCC）、清洁度评分以及在混凝土和橡胶垫地面上饲养的奶牛的行为。为此，19 头荷斯坦-弗里斯兰奶牛被分为混凝土组和橡胶垫组。从乳头末端采集拭子样本，以确定引起环境性乳腺炎的细菌数量。从所有四个乳区采集牛奶样本，以测定 SCC。采用瞬时取样法观察奶牛的行为活动。对奶牛进行目测评估，以确定乳房清洁度得分。所得数据采用独立样本 t 检验进行统计分析。大肠菌群（P
期刊介绍：
The journal was created as the Croce Azzurra in 1950.
A quarterly peer-reviewed journal devoted to veterinary public health and other aspects of veterinary science and medicine, Veterinaria Italiana is published by the Istituto Zooprofilattico Sperimentale dell’Abruzzo e del Molise ‘G. Caporale’ (Istituto Zooprofilattico Sperimentale dell''Abruzzo e del Molise) in Teramo, Italy.
The goal of the journal is to provide an international platform for veterinary public health information from Italy and other countries, particularly those in Eastern Europe and Africa, Asia and South America. Veterinarians and veterinary public health specialists are encouraged to share their knowledge and experience on this platform.
