We examined the relationship between physicochemical indicators and somatic cells in the milk of dairy cows during experimentally induced mastitis and their significance as indicators for use in controlling udder health. We were concerned particularly with the effect of alveolar milk ejection on the sensitivity of these indicators. In Expt 1, Escherichia coli lipopolysaccharide (Esch. coli LPS)...

The study examined whether the performance characteristics of male university field hockey players differed when match format was 2 × 35 min halves compared to 17.5 quarters. Thirty-five (age 21.2 ± 3.0 years, height 1.81 0.07 m, body mass 75.1 8.9 kg), competing at national level in UK, were monitored over 52 matches played across 2018–2019 (2 halves) and 2019–2020 quarters) seasons using 15 H...

Much emphasis has been put on evaluating alterations in milk composition caused by clinical and subclinical mastitis. However, little is known about changes in milk composition during subclinical mastitis in individual udder quarters with a low-to-moderate increase in milk somatic cell count (SCC). This information is needed to decide whether milk from individual udder quarters with a moderate-...

A randomized controlled field trial was performed to evaluate the efficacy of a 3-d treatment regimen with i.m. penethamate hydriodide compared with no treatment in lactating cows with subclinical mastitis. To be included, a cow had to have 2 somatic cell counts (SCC) 300,000 cells/mL at the last 3 monthly controls, 1 or more quarters with SCC >250,000 cells/mL, and the same bacterial species i...

Two experiments were conducted, the first to determine whether numbers of recovered bacteria differed due to sampling method used or due to location on carcass sampled (breast or leg quarters) and the second to determine if numbers of bacteria differed between the front (ventral) and back (dorsal) side of the carcass. In both experiments, eviscerated broiler carcasses were obtained from a comme...

Two experiments were conducted; the first to determine whether numbers of recovered bacteria differed due to sampling method used or due to location on carcass sampled (breast or leg quarters), and the second to determine if numbers of bacteria differed between ventral and dorsal sides of the carcass. In both experiments eviscerated broiler carcasses were obtained from a commercial processing p...
